[0059] As shown in FIG. 5, the embroidery device 140 includes a main body 141, engagement claws 46 and 47, the connector 49, a carriage 142, and the holder 143. The main body 141 has a rectangular shape that is long in the left-right direction. The dimension of the main body 141 in the front-rear direction is longer than the dimension of the bed 10 in the front-rear direction. The dimension of the main body 141 in the left-right direction is longer than the dimension of the free arm 102 of the bed 10 in the left-right direction. A recess 148 is formed in the main body 141. The recess 148 is recessed leftward from a central portion of a right surface 149 of the main body 141 in the front-rear direction. A cylindrical engagement protrusion 138 protruding rightward is provided on a left surface 137 of the recess 148. When the embroidery device 140 is attached to the bed 10, the engagement protrusion 138 is inserted into the engagement hole 161 of the bed 10, and is detachably engaged with the first mount portion 130, more specifically, the first side plate 113. In a state where the embroidery device 140 is attached to the first mount portion 130, the free arm 102 of the bed 10 is disposed in the recess 148.

[0060] The main body 141 has a first extension surface 139 extending horizontally. The first extension surface 139 is an upper surface of the main body 141. In a state where the embroidery device 140 is attached to the first mount portion 130, the first extension surface 139 is on the same plane as the bed surface 110. The main body 141 includes an X movement mechanism 146 and an X motor 144 shown in FIG. 19. The X movement mechanism 146 moves the carriage 142 in the left-right direction, that is, in the X direction. The X motor 144 drives the X movement mechanism 146.

[0061] The engagement claws 46 and 47 protrude rightward from the right surface 149 of the main body 141 at a position rearward of the recess 148. The engagement claws 46 and 47 are arranged in the front-rear direction. When the embroidery device 140 is attached to the bed 10, the engagement claw 46 is inserted into the engagement hole 119 and is detachably engaged with the first mount portion 130, more specifically, the first side plate 111. The engagement claw 47 of the embroidery device 140 is inserted into the engagement hole 120 and is detachably engaged with the first mount portion 130, more specifically, the first side plate 111.

[0062] The connector 49 protrudes rightward from the right surface 149 at a position forward of the recess 148. When the embroidery device 140 is attached to the bed 10, the connector 49 is electrically connected to a connector provided in the connection portion 133.

[0063] The carriage 142 includes the holder 143, a Y movement mechanism 147, and a Y motor 145 shown in FIG. 19. The holder 143 is disposed on the right side surface of the carriage 142. The Y movement mechanism 147 moves the holder 143 in the front-rear direction, that is, in the Y direction. The Y motor 145 drives the Y movement mechanism 147.

[0064] Referring to FIGS. 2 and 9 to 12B, the wide table 3 will be described. As shown in FIG. 2, the wide table 3 is detachably attached to the second mount portion 132 of the bed 10. In a state where the wide table 3 is attached to the bed 10, the wide table 3 is disposed rearward of the bed 10.

[0065] As shown in FIGS. 9 to 12B, the wide table 3 includes a table plate 31, legs 41, 42 and 43, a first lever 35, a second lever 34, and a lock release member 45. The table plate 31 is a plate shape that is long in the left-right direction in a plan view. In a state where the wide table 3 is attached to the bed 10, the table plate 31 has a second extension surface 32 that extends horizontally, that is, in a direction perpendicular to the upper-lower direction. The second extension surface 32 is an upper surface of the table plate 31. In a state where the wide table 3 is attached to the bed 10, the second extension surface 32 is on the same plane as the bed surface 110 or is several millimeters (mm) below the bed surface 110. When the embroidering device 140 is attached to the bed 10, the second extension surface 32 of the present example is set to be 2 mm below the bed surface 110. Since the second extension surface 32 is located below the bed surface 110, the second extension surface 32 does not hinder a horizontal movement of the embroidery frame 150. In this case as well, the second extension surface 32 supports the embroidery frame 150 when the embroidery frame 150 is bent downward by the weight of the sewing workpiece. In a case where an auxiliary device 170 or an auxiliary device 200 described later is attached to the bed 10 for performing practical sewing, the second extension surface 32 may be on the same plane as the bed surface 110. The height of the second extension surface 32 in a case where the wide table 3 is attached to the bed 10 may be changeable according to the auxiliary device attached to the bed 10. The difference in height between the bed surface 110 and the second extension surface 32 in a case where the wide table 3 is attached to the bed 10 is within 3 mm or within 2 mm, for example. Marks 321 and 322 are arranged on the second extension surface 32. The marks 321 and 322 indicate the positions of the first lever 35 and the second lever 34 in the left-right direction, respectively. The table plate 31 includes a protrusion 311 that protrudes downward from a lower surface 310 of the table plate 31. The protrusion 311 is disposed rightward of the center of the lower surface 310.

[0066] The legs 41, 42 and 43 are coupled to the lower surface 310 of the table plate 31. Each of the legs 41, 42 and 43 is coupled to the table plate 31 so as to be pivotable about a horizontally extending pivot shaft between a use position at which the leg extends vertically and a storage position at which the leg extends horizontally. The leg 41 is supported at a front end portion of the lower surface 310 of the table plate 31 and at the center in the left-right direction so as to be pivotable about a pivot shaft 411 extending in the left-right direction. The leg 42 is supported by a rear right end portion of the lower surface 310 of the table plate 31 so as to be pivotable about a pivot shaft 421 extending in the left-right direction. The leg 43 is supported by a rear left end portion of the lower surface 310 of the table plate 31 so as to be pivotable about a pivot shaft 431 extending in the left-right direction.

[0067] The first lever 35 and the second lever 34 protrude in the insertion direction K1, that is, protrude forward from a cutout 331 formed in a front surface 33 of the table plate 31. The insertion direction K1 is one direction along the short direction D1 of the bed surface 110 that extends horizontally in the sewing machine 1. The cutout 331 is recessed upward from the lower end of the front surface 33. The first lever 35 and the second lever 34 are located farther in the first direction N1 than the center of the table plate 31 in the longitudinal direction D2. The first lever 35 and the second lever 34 have plate shapes parallel to the bed surface 110 and elongated in the front-rear direction. The second lever 34 is located leftward of the first lever 35.

[0068] The first lever 35 is provided in a bilaterally symmetrical manner with the second lever 34. The first lever 35 includes a pivot shaft 351, a first hook 37, a first inclined portion 39, a first detachment end portion 352, and a spring support portion 353. The pivot shaft 351 extends in the upper-lower direction near the center of the first lever 35 in the front-rear direction. The first lever 35 is supported by the table plate 31 so as to be pivotable about the pivot shaft 351 between a first normal position shown in FIGS. 10A and 12A and a first attachment-detachment position shown in FIGS. 10B and 12B. At the first attachment-detachment position, the first hook 37 is located farther in the second direction N2, that is, farther leftward, than the first hook 37 at the first normal position.

[0069] The first hook 37 protrudes from the front end of the first lever 35 in the first direction N1, that is, rightward. The first inclined portion 39 is located between the first hook 37 and the front end of the first lever 35, that is, an end 350 of the first lever 35 in the insertion direction K1. The first inclined portion 39 is inclined in the longitudinal direction D2, more specifically, inclined leftward toward the front. The first detachment end portion 352 is an end portion of the first lever 35 in the detachment direction K2. A left portion of the first detachment end portion 352 protrudes leftward and contacts a protrusion 456 of the lock release member 45 described later. The spring support portion 353 is a hook disposed at an end of the first lever 35 in the detachment direction K2. The spring support portion 353 supports the right end of a spring 30. The spring 30 is a coil spring. The first lever 35 is urged by the spring 30 in the clockwise direction in a bottom view about the pivot shaft 351. The first lever 35 is inserted into the opening 65 and then the first lever 35 pivots from the first attachment-detachment position to the first normal position, whereby the first hook 37 engages with the second mount portion 132.

[0070] The second lever 34 includes a pivot shaft 341, a second hook 36, a second inclined portion 38, a second detachment end portion 342, and a spring support portion 343. The pivot shaft 341 extends in the upper-lower direction near the center of the second lever 34 in the front-rear direction. The second lever 34 is supported by the table plate 31 so as to be pivotable about the pivot shaft 341 between a second normal position shown in FIGS. 10A and 12A and a second attachment-detachment position shown in FIGS. 10B and 12B. At the second attachment-detachment position, the second hook 36 is located farther in the first direction N1, that is, farther rightward, than the second hook 36 at the second normal position.

[0071] The second hook 36 protrudes from the front end of the second lever 34 in the second direction N2, that is, leftward. The second inclined portion 38 is located between the second hook 36 and an end 340 of the second lever 34 in the insertion direction K1, that is, the front end of the second lever 34. The second inclined portion 38 is inclined in the longitudinal direction D2, more specifically, inclined rightward toward the front. The second detachment end portion 342 is an end portion of the second lever 34 in the detachment direction K2. A right portion of the second detachment end portion 342 protrudes rightward and contacts the protrusion 456 of the lock release member 45 described later. The spring support portion 343 is a hook provided at an end of the second lever 34 in the detachment direction K2, that is, at the rear end. The spring support portion 343 supports the left end of the spring 30. The second lever 34 is urged by the spring 30 in the counterclockwise direction in a bottom view about the pivot shaft 341. The second lever 34 is inserted into the opening 65 of the second mount portion 132 and then pivots from the second attachment-detachment position to the second normal position, whereby the second hook 36 engages with the second mount portion 132.

[0072] The lock release member 45 is connected to the first lever 35 and the second lever 34. The lock release member 45 is supported by the lower surface 310 of the table plate 31 so as to be movable from a first position shown in FIGS. 10A and 12A to a second position shown in FIGS. 10B and 12B. The lock release member (lock release plate) 45 has a plate shape parallel to the bed surface 110 of the table plate 31. The lock release member 45 and the table plate 31 sandwiches the first lever 35 and the second lever 34 in the upper-lower direction. The lock release member 45 includes a base plate 451 and the protrusion 456. The protrusion 456 protrudes upward from the upper surface of a front portion of the base plate 451 in a cylindrical shape. The protrusion 456 contacts each of the first detachment end portion 352 of the first lever 35 and the second detachment end portion 342 of the second lever 34. A hole 455 formed through the upper-lower direction is formed at a rear portion of the base plate 451. The base plate 451 functions as a handle that is operated by a user with his or her finger inserted into the hole 455.

[0073] Elongated holes 452, 453 and 454 which are long in the front-rear direction are formed in the base plate 451. The elongated hole 452 is formed in a front right portion of the base plate 451, and the pivot shaft 351 is inserted into the elongated hole 452. The elongated hole 453 is formed in a front left portion of the base plate 451, and the pivot shaft 341 is inserted into the elongated hole 453. The elongated hole 454 is formed in a center portion of the base plate 451, and the protrusion 311 is inserted into the elongated hole 454. The elongated holes 452, 453 and 454 guide the movement of the lock release member 45 between the first position and the second position. FIG. 10A is a bottom view of the wide table 3 when the lock release member 45 is at the first position, the first lever 35 is at the first normal position, and the second lever 34 is at the second normal position. FIG. 10B is a bottom view of the wide table 3 when the lock release member 45 is at the second position, the first lever 35 is at the first attachment-detachment position, and the second lever 34 is at the second attachment-detachment position. As shown in FIG. 10A, when the lock release member 45 is at the first position, the pivot shaft 351 is located at the rear end of the elongated hole 452, the pivot shaft 341 is located at the rear end of the elongated hole 453, and the protrusion 311 is located at the rear end of the elongated hole 454. As shown in FIG. 10B, the position of the lock release member 45 with respect to the table plate 31 when the lock release member 45 is at the second position is farther rearward than the position of the lock release member 45 with respect to the table plate 31 when the lock release member 45 is at the first position. When the lock release member 45 is at the second position, the pivot shaft 351 is located at the front end of the elongated hole 452, the pivot shaft 341 is located at the front end of the elongated hole 453, and the protrusion 311 is located at the front end of the elongated hole 454.

[0074] FIG. 12A is a bottom view of the wide table 3 when the lock release member 45 is at the first position, the first lever 35 is at the first normal position, and the second lever 34 is at the second normal position, corresponding to a cross-sectional view taken along a line XII-XII in FIG. 11. FIG. 12B is a bottom view of the wide table 3 when the lock release member 45 is at the second position, the first lever 35 is at the first attachment-detachment position, and the second lever 34 is at the second attachment-detachment position, corresponding to a cross-sectional view taken along the line XII-XII in FIG. 11. As shown in FIG. 12A, the wide table 3 includes a first protrusion 462 and a second protrusion 461. The first protrusion 462 and the second protrusion 461 of the present embodiment protrude upward from the upper surface of the lock release member 45. When the first lever 35 is located at the first normal position and the wide table 3 is moved in the first direction N1 with respect to the bed 10, the first protrusion 462 contacts the first detachment end portion 352 of the first lever 35. More specifically, when the first lever 35 is located at the first normal position and the wide table 3 is moved in the first direction N1 with respect to the bed 10, a portion close to the end 350 of the first lever 35 in the insertion direction K1 contacts and is pressed by the engagement edge 66 (the edge in the first direction N1) of the second mount portion 132, and the first lever 35 pivots counterclockwise in the bottom view (FIG. 12A) about the pivot shaft 351. At this time, the first detachment end portion 352 in the detachment direction K2 of the first lever 35 moves in the first direction N1, and thus contacts the first protrusion 462. The first protrusion 462 is located farther in the first direction N1 than the first detachment end portion 352. When the second lever 34 is at the second normal position and the wide table 3 is moved in the second direction N2 with respect to the bed 10, the second protrusion 461 contacts the second detachment end portion 342 of the second lever 34. More specifically, when the second lever 34 is at the second normal position and the wide table 3 is moved in the second direction N2 with respect to the bed 10, a portion close to the end 340 of the second lever 34 in the insertion direction K1 contacts and is pressed by the engagement edge 66 (the edge in the second direction N2) of the second mount portion 132, and the second lever 34 pivots clockwise in the bottom view (FIG. 12A) about the pivot shaft 341. At this time, the second detachment end portion 342 in the detachment direction K2 of the second lever 34 moves in the second direction N2, and thus contacts the second protrusion 461. The second protrusion 461 is located farther in the second direction N2 than the second detachment end portion 342. When a force in the left-right direction is applied to the wide table 3 in a state where the wide table 3 is attached to the bed 10, the second protrusion 461 and the first protrusion 462 prevent the second lever 34 and the first lever 35 from pivoting against the urging force of the spring 30 and rattling. The second protrusion 461 and the first protrusion 462 are configured to restricting pivoting of the second lever 34 and the first lever 35, thereby preventing the wide table 3 from being unintentionally detached.

[0075] When the wide table 3 is attached to the bed 10, the user inserts the second lever 34 and the first lever 35 of the wide table 3 into the opening 65 while using the marks 321 and 322 of the second extension surface 32 as a mark in a state where the legs 41 to 43 are arranged at the use position. When the wide table 3 is attached to the bed 10, the cover 62 of the second mount portion 132 is pushed in the insertion direction K1 by the first lever 35 and the second lever 34, and thereby pivots from the closed position to the open position. The first lever 35 is inserted into the opening 65 while the first inclined portion 39 contacts the engagement edge 66, and thus the first lever 35 pivots from the normal position to the attachment-detachment position against the urging force of the spring 30. The second lever 34 is inserted into the opening 65 while the second inclined portion 38 contacts the engagement edge 66, and thus the second lever 34 pivots from the normal position to the attachment-detachment position against the urging force of the spring 30. After the first hook 37 of the first lever 35 and the second hook 36 of the second lever 34 are inserted through the opening 65 in the insertion direction K1, the first lever 35 and the second lever 34 pivot from the attachment-detachment position to the normal position by the urging force of the spring 30. This causes the first hook 37 and the second hook 36 to engage with the second mount portion 132. The lock release member 45 is pushed in the insertion direction K1 by each of the first detachment end portion 352 of the first lever 35 and the second detachment end portion 342 of the second lever 34, and moves from the second position to the first position.

[0076] As shown in FIG. 2, when the wide table 3 is attached to the bed 10, the end portion of the wide table 3 in the first direction N1 is located farther in the second direction N2 than the pillar 11 in the longitudinal direction D2. That is, the right end of the wide table 3 is located between the pillar 11 and the first side plate 111 in the longitudinal direction D2. In the longitudinal direction D2, the end portion of the wide table 3 in the second direction N2 is located farther in the second direction N2 than the first side plate 111. That is, the left end of the wide table 3 is located between the first side plate 111 and the first side plate 113 in the longitudinal direction D2. The wide table 3 is disposed rearward of the bed 10 and is not disposed forward of the bed 10. The front surface 33 of the wide table 3 contacts the second side plate 122, and the second extension surface 32 forms a flat surface continuous with the bed surface 110. In a state where the legs 41 to 43 are at the use position, the table plate 31, the first lever 35, and the second lever 34 are located above a center M1 of the wide table 3 in the upper-lower direction. Since the first lever 35 and the second lever 34 engage with the second mount portion 132 of the bed 10 above the center M1 of the wide table 3 in the upper-lower direction, a gap is less likely to be formed between the second extension surface 32 and the bed surface 110, compared with the case where the first lever 35 and the second lever 34 engage with the second mount portion 132 of the bed 10 below the center of the wide table 3 in the upper-lower direction. The wide table 3 is disposed below a rear right portion of the embroidery frame 150, and supports the rear right portion of the embroidery frame 150 when the embroidery frame 150 is bent downward by the weight of the sewing workpiece. Scissors may be placed in a space below the table plate 31, for example.

[0077] When the wide table 3 is detached from the bed 10, the user places his or her finger on the hole 455 of the lock release member 45 of the wide table 3 and moves the lock release member 45 rearward. The lock release member 45 is guided by the elongated holes 452 to 454 to move from the first position to the second position. In the process of the lock release member 45 moving from the first position to the second position, the protrusion 456 causes the first lever 35 to pivot counterclockwise in a bottom view against the urging force of the spring 30. The protrusion 456 causes the second lever 34 to pivot clockwise in a bottom view against the urging force of the spring 30. As a result, the protrusion 456 of the lock release member 45 causes the first lever 35 to pivot from the first normal position to the first attachment-detachment position and causes the second lever 34 to pivot from the second normal position to the second attachment-detachment position, thereby releasing the engagement between the first hook 37, the second hook 36 and the second mount portion 132. The user moves the wide table 3 from the bed 10 in the detachment direction K2, pulls out the first lever 35 and the second lever 34 of the wide table 3 from the opening 65, and then releases the lock release member 45. The first lever 35 and the second lever 34 pivot from the attachment-detachment position to the normal position by the urging force of the spring 30. The lock release member 45 is pushed in the insertion direction K1 by each of the first detachment end portion 352 of the first lever 35 and the second detachment end portion 342 of the second lever 34, and moves from the second position to the first position. This configuration allows the user to store the wide table 3 in a compact manner in a state where the legs 41 to 43 are arranged at the storage positions.

[0078] Referring to FIGS. 1 and 13 to 15, the wide table 7 will be described. As shown in FIG. 1, the wide table 7 is detachably attached to the second mount portion 131 of the bed 10. In a state where the wide table 7 is attached to the bed 10, the wide table 7 is disposed forward of the bed 10.

[0079] As shown in FIGS. 13 to 15, the wide table 7 includes a table plate 71, legs 81 and 82, a lever 84, a protrusion 74, a lock release member 90, and a spring 80. The table plate 71 has a rectangular shape elongated in the left-right direction in a plan view. The left rear portion of the table plate 71 is recessed forward. The table plate 71 has a second extension surface 72 that extends horizontally, that is, in a direction perpendicular to the upper-lower direction. In a state where the wide table 7 is attached to the bed 10, the second extension surface 72 is on the same plane as the bed surface 110 or is several millimeters below the bed surface 110. Protrusions 87 and 88 protruding downward are disposed on a lower surface 710 of the table plate 71. The protrusion 87 is disposed at a right rear portion of the lower surface 710. The protrusion 88 is provided at a rear portion and a central portion in the left-right direction of the lower surface 710.

[0080] As shown in FIGS. 14A to 14C, the lever 84 is integrally formed with the lock release member 90. The lever 84 includes a protruding portion 841 that protrudes rightward from a rear end portion of a base plate 843 of the lock release member 90. The lever 84 protrudes rearward from a rear surface 73 of the table plate 71 at a position farther in the first direction N1 than the center of the longitudinal direction D2 of the table plate 71. The lever 84 includes a hook 85 that protrudes from a right rear portion of the protruding portion 841 in the first direction N1 at a position rearward of the rear surface 73 of the table plate 71. In the wide table 7, the lever 84 includes an inclined portion 86 located between the hook 85 and an end 83 of the lever 84 in the insertion direction J1, that is, the rear end of the lever 84. The inclined portion 86 is inclined in the longitudinal direction D2, more specifically, inclined leftward toward the rear. An elongated hole 842 extending in an arc shape in the left-right direction is formed in a right end portion of the protruding portion 841. The protrusion 87 is inserted into the elongated hole 842. The protrusion 74 protrudes rearward from the rear surface 73 of the table plate 71 at a position farther in the second direction N2 than the lever 84.

[0081] The lock release member 90 is connected to the lever 84, and is supported by the table plate 71 so as to be movable from the first position to the second position. The lock release member 90 includes the base plate 843, a support arm 846, and a protrusion 847. The base plate 843 have a hole 845 and an elongated hole 844 that are formed through the base plate 843 in the upper-lower direction. The hole 845 has a rectangular shape in a bottom view. The elongated hole 844 is formed in an arc shape at the left rear of the hole 845, and is inclined rightward toward the rear. The protrusion 88 is inserted into the elongated hole 844. The support arm 846 extends rightward from a right front portion of the base plate 843. A boss 712 extending downward in a cylindrical shape from the lower surface 710 of the table plate 71 is inserted into the right end of the support arm 846. The support arm 846 is attached to the table plate 71 by a screw 89 so as to be pivotable about the boss 712. That is, the lever 84 and the lock release member 90 are attached to the table plate 71 so as to be pivotable about the boss 712 while being guided by the elongated holes 842 and 844. The protrusion 847 extends leftward from the left end of the base plate 843.

[0082] As shown in FIG. 15, the spring 80 is disposed between the lower surface 710 of the table plate 71 and the protruding portion 841. The spring 80 urges the lock release member 90 in a direction from the second position toward the first position. The spring 80 is a coil spring. One end of the spring 80 is fixed to a flange 711 extending downward from the lower surface 710 of the table plate 71. The other end of the spring 80 is fixed to a protrusion 848 that protrudes upward from the upper surface of the protruding portion 841.

FIG. 14B is a bottom view of the wide table 7 when the lock release member 90 is at the first position, the lever 84 is at the normal position, and the legs 81 and 82 are at the use position. FIG. 14C is a bottom view of the wide table 7 when the lock release member 90 is at the second position, the lever 84 is at the attachment-detachment position, and the legs 81 and 82 are at the use position. The leg 81 is coupled to a left portion of the lower surface 710 of the table plate 71 so as to be pivotable about a pivot shaft 811 extending horizontally between a use position at which the leg extends vertically and a storage position at which the leg extends horizontally. The leg 82 is connected to a right portion of the lower surface 710 of the table plate 71 so as to be pivotable about a pivot shaft 821 extending horizontally between a use position at which the leg extends vertically and a storage position at which the leg extends horizontally. As shown in FIG. 14A, when the leg 81 is at the storage position, the leg 81 and the protrusion 847 of the lock release member 90 contact each other, and the lock release member 90 is not movable from the first position to the second position. When the leg 82 is at the storage position, the leg 82 and the protruding portion 841 of the lever 84 contact each other, and the lock release member 90 is not movable from the first position to the second position.

[0084] When the wide table 7 is attached to the bed 10, the user inserts the lever 84 and the protrusion 74 of the wide table 7 into the opening 67 of the second mount portion 131 in a state where the legs 81 and 82 are moved from the storage position shown in FIG. 14A to the use position shown in FIG. 14B. When the wide table 7 is attached to the bed 10, the cover 69 of the second mount portion 131 is pushed in the insertion direction J1 by the lever 84, and thereby pivots from the closed position to the open position. The lever 84 is inserted into the opening 67 while the inclined portion 86 and the protrusion 74 contact the engagement edge 68, whereby the lever 84 pivots about the screw 89 from the normal position shown in FIG. 14B to the attachment-detachment position shown in FIG. 14C. After the hook 85 of the lever 84 is inserted into the opening 67 in the insertion direction J1, the lever 84 pivots from the attachment-detachment position to the normal position by the urging force of the spring 80, and the lock release member 90 pivots from the second position to the first position. This causes the hook 85 to engage with the second mount portion 131.

[0085] As shown in FIG. 1, in a state where the wide table 7 is attached to the bed 10, the end of the wide table 7 in the first direction N1 is located farther in the second direction N2 than the pillar 11 in the longitudinal direction D2. That is, the right end of the wide table 7 is located between the pillar 11 and the left end of the bed 10 in the longitudinal direction D2. In the longitudinal direction D2, the end of the wide table 7 in the second direction N2 is located farther in the second direction N2 than the first side plate 111. That is, the left end of the wide table 7 is located between the first side plate 111 and the first side plate 113 in the longitudinal direction D2. The wide table 7 is disposed forward of the bed 10, and is not disposed rearward of the bed 10. The rear surface 73 of the wide table 7 contacts the second side plate 121, and the second extension surface 72 forms a flat surface continuous with the bed surface 110. The lever 84 engages with the second mount portion 131 of the bed 10 above a center M2 of the wide table 7 in the upper-lower direction when the legs 81 and 82 are at the use position. Thus, a gap is less likely to be formed between the second extension surface 72 and the bed surface 110, compared with the case where the lever 84 engages with the second mount portion 131 of the bed 10 below the center of the wide table 7 in the upper-lower direction when the legs 81 and 82 are at the use position. The wide table 7 is disposed below a front right portion of the embroidery frame 150, and supports the front right portion of the embroidery frame 150 when the embroidery frame 150 is bent downward by the weight of the sewing workpiece.

[0086] When the wide table 7 is detached from the bed 10, the user places his or her finger on the hole 845 of the lock release member 90 of the wide table 7 and moves the lock release member 90 in the detachment direction J2, that is, forward. The lock release member 90 moves from the first position shown in FIG. 14B to the second position shown in FIG. 14C about the screw 89. The lever 84 pivots from the normal position shown in FIG. 14B to the attachment-detachment position shown in FIG. 14C, and release the engagement between the hook 85 and the second mount portion 131. The user moves the wide table 7 from the bed 10 in the detachment direction J2 and then releases the lock release member 90. The lever 84 pivots from the attachment-detachment position to the normal position by the urging force of the spring 80, and the lock releasing member 90 pivots from the second position to the first position. This configuration allows the user to store the wide table 7 in a compact manner in a state where the legs 81 and 82 are disposed at the storage position.

[0092] An electrical configuration of the sewing machine 1 will be described with reference to FIG. 19. The controller 2 of the sewing machine 1 includes a CPU 75, a ROM 76, a RAM 77, a memory (storage) 78, and an input-output (I/O) interface 70. The CPU 75 is connected to the ROM 76, the RAM 77, the memory 78, and the input-output interface 70 via a bus 79.

[0093] The CPU 75 performs main control of the sewing machine 1, and executes various types of calculation and processing relating to sewing in accordance with various types of programs stored in the ROM 76. The ROM 76 includes a plurality of storage areas including a program storage area, which are not shown. The program storage area stores various programs for operating the sewing machine 1, including a program for executing a main process that will be described later.

[0094] The RAM 77 has a storage area for storing operation results of the operation processing performed by the CPU 75, for example. The memory 78 stores various parameters for the sewing machine 1 to execute various processing, for example. The memory 78 stores sewing data for sewing various sewing patterns that are sewable by the sewing machine 1, for each of a plurality of sewing patterns. The sewing data includes coordinate data. The coordinate data is data that indicates formation positions of stitches included in a sewing pattern, that is, the positions of needle points, by the coordinates of the embroidery coordinate system. That is, the coordinate data includes data representing a plurality of coordinates for each needle point. The memory 78 stores, as frame type information, correspondence between types of embroidery frames that are attachable to the holder 143 and sewing regions. The sewing region is a sewable region that is set inside the embroidery frame that is attached to the holder 143 of the sewing machine 1. The memory 78 stores, as a large frame, an embroidery frame having a size larger than or equal to a particular size.

[0095] The input-output interface 70 is connected to drive circuits 91, 92, 93 and 94, the touch screen 26, the start-stop switch 29, a frame sensor 22, and table sensors 20 and 24. The frame sensor 22 is configured to detect that an embroidery frame has been attached to the embroidery device 140, and to output a detection result corresponding to the type of the embroidery frame. The frame sensor 22 of the present example detects the type of the embroidery frame in accordance with a combination of ON and OFF of a plurality of mechanical switches. The table sensor 20 is configured to mechanically detect whether the wide table 7 is attached to the second mount portion 131 of the bed 10 and output a detection result. The table sensor 24 is configured to mechanically detect whether the wide table 3 is attached to the second mount portion 132 of the bed 10 and output a detection result.

[0096] The sewing machine motor 25 is connected to the drive circuit 91. The drive circuit 91 drives the sewing machine motor 25 in accordance with a control signal from the CPU 75. In accordance with the driving of the sewing machine motor 25, the needle bar 6 swings in the upper-lower direction via the main drive shaft. The drive circuit 92 drives the LCD 21 in accordance with a control signal from the CPU 75, thereby displaying an image on the LCD 21. The X motor 144 is connected to the drive circuit 93. The Y motor 145 is connected to the drive circuit 94. The drive circuits 93 and 94 drive the X motor 144 and the Y motor 145, respectively, in accordance with control signals from the CPU 75. In accordance with the driving of the X motor 144 and the Y motor 145, the embroidery frame 150 attached to the embroidery device 140 moves in the X direction and the Y direction by the movement amount corresponding to the control signal.

[0097] The operation of the sewing machine 1 will be briefly described. When embroidery sewing is performed using the embroidery frame 150, the needle bar 6 is swung in the upper-lower direction in conjunction with an operation in which the embroidery frame 150 is moved in the X direction and the Y direction by the embroidery device 140. In this way, a sewing pattern is sewn on the sewing workpiece held by the embroidery frame 150 by the sewing needle 4 attached to the needle bar 6.

[0098] The main process will be described with reference to FIG. 20. In response to acquiring a selection instruction to select a sewing pattern that is the target of embroidery sewing, the CPU 75 of the sewing machine 1 reads and executes a program to perform the main process. The selection instruction may be input to the sewing machine 1 from an external device, or may be input via the touch screen 26. The program includes an instruction to cause the CPU 75 to execute the following processing. Various data obtained in the main process are stored in the RAM 77 as appropriate. Hereinafter, a step is abbreviated as S.

[0099] As shown in FIG. 20, the CPU 75 acquires sewing data of the sewing pattern included in the selection instruction (S1). The CPU 75 acquires the type of the embroidery frame 150 attached to the holder 143 based on the detection result of the frame sensor 22 (S2). The CPU 75 determines whether the embroidery frame 150 attached to the holder 143 is a large frame based on whether the type of the embroidery frame 150 acquired in S2 is stored as a large frame in the memory 78 (S3). In response to determining that the embroidery frame attached to the holder 143 is not the large frame (S3: NO), the CPU 75 determines whether a sewing instruction has been detected (S11). In response to determining that the sewing instruction has not been detected (S11: NO), the CPU 75 returns the processing to S11. In response to determining that the sewing instruction has been detected (S11: YES), the CPU 75 performs normal embroidery sewing in accordance with the sewing data acquired in S1 (S12).

[0100] In the specific examples, it is determined that the embroidery frame 150 attached to the holder 143 is a large frame (S3: YES). Thus, the CPU 75 performs a notification process (S4) based on the detection result of the frame sensor 22. The notification process is a process of, in a case where the embroidery frame 150 of a particular size is attached, notifying that the wide table 7 is to be attached to the second mount portion 131 and the wide table 3 is to be attached to the second mount portion 132. Specifically, the CPU 75 controls the LCD 21 to display a message for prompting to attach the wide table 7 to the second mount portion 131 and to attach the wide table 3 to the second mount portion 132.

[0101] The CPU 75 determines whether a sewing instruction has been detected (S5). In response to determining that the sewing instruction has not been detected (S5: NO), the CPU 75 returns the processing to S5. In response to determining that the sewing instruction has been detected (S5: YES), the CPU 75 determines whether the wide table 7 is attached to the second mount portion 131 and the wide table 3 is attached to the second mount portion 132 based on the detection results of the table sensors 20 and 24 (S6). In response to determining that the wide table 7 is attached to the second mount portion 131 and the wide table 3 is attached to the second mount portion 132 (S6: YES), the CPU 75 drives the needle bar 6 in the upper-lower direction at a second speed that is faster than a first speed, and performs embroidery sewing in accordance with the sewing data acquired in S1 (S7).

[0102] In response to determining that the wide table is not attached to at least the second mount portion 131 or the second mount portion 132 (S6: NO), the CPU 75 performs a warning process of outputting a warning (S8). Specifically, the CPU 75 controls the LCD 21 to display a message to warn that sewing will be performed in a state where the wide table is not attached to at least the second mount portion 131 or the second mount portion 132. The CPU 75 drives the needle bar 6 in the upper-lower direction at the first speed in accordance with the sewing data acquired in S1, and performs embroidery sewing in accordance with the sewing data acquired in S1 (S9). After S7, S9 or S12, the CPU 75 ends the main process.

[0103] Referring to FIGS. 21 to 23, a wide table 500 of a first modification will be described. Although not shown, the wide table 500 is detachably attached to the second mount portion 132 of the bed 10.

An elongated hole 552 extending in an arc shape in the left-right direction is formed in a right end portion of the lever 59. The protrusion 538 is inserted into the elongated hole 552. The protrusion 540 protrudes forward from the front surface 533 of the table plate 531 at a position farther in the second direction N2 than the lever 59.

[0106] The lock release member 58 is connected to the lever 59, and is supported by the table plate 531 so as to be movable from a first position to a second position. The lock release member 58 includes the base plate 553, a support arm 556, and a protrusion 558. A hole 555 and an elongated hole 554 are formed through the base plate 553 in the upper-lower direction. The hole 555 has a rectangular shape in a bottom view. The elongated hole 554 is formed in an arc shape at the left front of the hole 555 so as to be inclined rightward toward the front. The protrusion 537 is inserted into the elongated hole 554. The support arm 556 extends rightward from a right rear portion of the base plate 553. A boss 560 is inserted into the right end of the support arm 556, and the support arm 556 is fixed to the table plate 531 by a screw 539 so as to be pivotable about the boss 560. That is, the lever 59 and the lock release member 58 are fixed to the table plate 531 so as to be pivotable about the boss 560 while being guided by the elongated holes 552 and 554. The protrusion 558 extends leftward from the left end of the base plate 553.

[0107] The spring 550 is disposed between the table plate 531 and the base plate 553 in the upper-lower direction. The spring 550 urges the lock release member 58 in a direction from the second position toward the first position. The spring 550 is a coil spring. One end of the spring 550 is fixed to a flange 572 that extends downwardly from the lower surface 571 of the table plate 531. The other end of the spring 550 is fixed to a protrusion 559 which protrudes upward from the upper surface of the protrusion 558.

[0108] FIG. 22A is a bottom view of the wide table 500 when the lock release member 58 is at the first position, the lever 59 is at the normal position, and the legs 541 and 542 are at the storage position. FIG. 22B is a bottom view of the wide table 500 when the lock release member 58 is at the first position, the lever 59 is at the normal position, and the legs 541 and 542 are at the use position. FIG. 22C is a bottom view of the wide table 500 when the lock release member 58 is at the second position, the lever 59 is at the attachment-detachment position, and the legs 541 and 542 are at the use position. The leg 541 is coupled to a right portion of the lower surface 571 of the table plate 531 so as to be pivotable about a pivot shaft 543 extending horizontally between a use position at which the leg extends vertically and a storage position at which the leg extends horizontally. The leg 542 is connected to a left portion of the lower surface 571 of the table plate 531 so as to be pivotable about a pivot shaft 544 extending horizontally between a use position at which the leg extends vertically and a storage position at which the leg extends horizontally. As shown in FIG. 22A, in a state where the leg 541 is at the storage position, the leg 541 and the lever 59 contact each other, and the lock release member 58 is not movable from the first position to the second position. In a state where the leg 542 is at the storage position, the leg 542 and the protrusion 558 contact each other, and the lock release member 58 is not movable from the first position to the second position.

[0109] When the wide table 500 is attached to the bed 10, the user inserts the lever 59 and the protrusion 540 of the wide table 500 into the opening 65 in a state where the legs 541 and 542 are moved from the storage position shown in FIG. 22A to the use position shown in FIG. 22B. When the wide table 500 is attached to the bed 10, the cover 62 of the second mount portion 132 is pushed in the insertion direction K1 by the lever 59, and thereby pivots from the closed position to the open position. The lever 59 is inserted into the opening 65 while the inclined portion 536 and the protrusion 540 contact the engagement edge 66, whereby the lever 59 pivots from the normal position shown in FIG. 22B to the attachment-detachment position shown in FIG. 22C. After the hook 535 of the lever 59 is inserted into the opening 65 in the insertion direction K1, the lever 59 pivots about the boss 560 from the attachment-detachment position to the normal position by the urging force of the spring 550. This causes the hook 535 to engage with the second mount portion 132. In a state where the legs 541 and 542 are at the use position, the table plate 531 and the lever 59 are located above a center M3 of the wide table 500 in the upper-lower direction.

[0110] When the wide table 500 is detached from the bed 10, the user places a finger on the hole 555 of the lock release member 58 of the wide table 500 and moves the lock release member 58 rearward. The lock release member 58 moves from the first position shown in FIG. 22B to the second position shown in FIG. 22C about the boss 560. The lever 59 pivots from the normal position shown in FIG. 22B to the attachment-detachment position shown in FIG. 22C, and the engagement between the hook 535 and the second mount portion 132 is released. The user moves the wide table 500 from the bed 10 in the detachment direction K2 and then releases the lock release member 58. The lever 59 pivots from the attachment-detachment position to the normal position by the urging force of the spring 550. This configuration allows the user to store the wide table 500 in a compact manner in a state where the legs 541 and 542 are arranged at the storage position.

[0111] Referring to FIG. 24, a wide table 600 of a second modification will be described. As shown in FIG. 24, the wide table 600 is detachably attached to the second mount portion 131 of the bed 10. In a state where the wide table 600 is attached to the bed 10, the wide table 600 is located forward of the bed 10. The wide table 600 includes a table plate 601, legs 604 and 605, and second magnets 606 and 607.

[0112] The table plate 601 has a rectangular shape that is long in the left-right direction in a plan view. The left rear portion of the table plate 601 is recessed forward. The table plate 601 has a second extension surface 602 that extends horizontally, that is, in a direction perpendicular to the upper-lower direction. In a state where the wide table 600 is attached to the bed 10, the second extension surface 602 is on the same plane as the bed surface 110 or is several millimeters below the bed surface 110. The second magnets 606 and 607 are fixed to a rear surface 603 of the table plate 601. The second magnets 606 and 607 are arranged in the left-right direction. The second magnet 606 has the same magnetic field direction as a first magnet 631. The second magnet 607 has the same magnetic field direction as a first magnet 632. The directions of the magnetic field of the second magnet 606 and the second magnet 607 are different. The directions of the magnetic fields of the first magnet 631 and the first magnet 632 are different. For example, in a case where the rear surface of the second magnet 606 is the S pole, the first magnet 631 is disposed at the sewing machine 1 such that the front surface of the first magnet 631 is the N pole. In this case, the first magnet 632 is disposed at the sewing machine 1 such that the rear surface of the second magnet 607 is the N pole and the front surface of the first magnet 632 is the S pole. In this way, the second magnets 606 and 607 disposed adjacent to each other are disposed so as to generate magnetic fields different from each other. The first magnets 631 and 632 disposed adjacent to each other are disposed so as to generate magnetic fields different from each other. That is, the first magnet 631 and the second magnet 606 attract each other by magnetic force, and the first magnet 632 and the second magnet 607 attract each other by magnetic force. In contrast, the first magnet 631 and the second magnet 607 repel each other with a repulsive force, and the first magnet 632 and the second magnet 606 repel each other with a repulsive force. Thus, the second magnets 606 and 607 contribute to the wide table 600 being attached to an appropriate position on the bed 10.

[0113] The leg 604 is coupled to a right portion of the lower surface of the table plate 601 so as to be pivotable about a pivot shaft extending horizontally between a use position at which the leg 604 extends vertically and a storage position at which the leg 604 extends horizontally. The leg 605 is connected to a left portion of the lower surface of the table plate 601 so as to be pivotable about a pivot shaft extending horizontally between a use position at which the leg 605 extends vertically and a storage position at which the leg 605 extends horizontally.

[0114] When the wide table 600 is attached to the bed 10, the user brings the second magnets 606 and 607 of the wide table 600 into contact with the first magnets 631 and 632 provided on the second side plate 121 of the sewing machine 1 in a state where the legs 604 and 605 have been moved to the use position shown in FIG. 24. The wide table 600 is attached to the bed 10 by the magnetic force between the first magnets 631 and 632 and the second magnets 606 and 607. When the wide table 600 is detached from the bed 10, the user moves the wide table 600 from the bed 10 in the detachment direction J2 against the magnetic force between the first magnets 631 and 632 and the second magnets 606 and 607. This configuration allows the user to store the wide table 7 in a compact manner in a state where the legs 604 and 605 are disposed at the storage position.

[0116] The sewing machine 1 of the above-described embodiment includes the bed 10. The bed 10 includes the bed surface 110, the first side plates 111 and 113, the second side plate 122, the first mount portion 130, and the second mount portion 132. The bed surface 110 extends horizontally, that is, in a direction perpendicular to the upper-lower direction. The first side plates 111 and 113 extend downward from the outer periphery 19 of the bed surface 110 and cross the longitudinal direction D2 of the bed surface 110. The second side plate 122 extends downward from the outer periphery 19 of the bed surface 110 and crosses the short direction D1 of the bed surface 110. The first mount portion 130 is configured that an auxiliary device having a first extension surface extending horizontally is attachable, and is provided at the first side plates 111 and 113. The second mount portion 132 is configured that the wide table 3 having the second extension surface 32 extending horizontally and having a shape different from that of the auxiliary device is attachable. The second mount portion 132 is provided at the second side plate 122. The sewing machine 1 is configured that the auxiliary device is attachable to the first mount portion 130 and the wide table 3 is attachable to the second mount portion 132. That is, the wide table 3 is attachable in a state where the auxiliary device is attached to the bed 10, and the bed surface 110 is extended by the second extension surface 32. Thus, the second mount portion 132 of the sewing machine 1 contributes to extending the surface on which the user places a sewing workpiece when sewing the sewing workpiece that is larger than the bed surface 110 and improving the convenience when sewing the sewing workpiece that is larger than the bed surface 110. The second mount portions 131 and 630 of the sewing machine 1 also contribute to achieving a similar effect to the second mount portion 132.

[0117] The wide table 3 is detachably attached to the second mount portion 132 of the bed 10. The wide table 3 includes the table plate 31 having the second extension surface 32. In a case where a large sewing workpiece is sewn, the sewing machine 1 supports the sewing workpiece by the bed 10 and the wide table 3 by attaching the wide table 3 to the bed 10, and thus the wide table 3 contributes to improving convenience during sewing. The wide tables 7, 500, and 600 also contribute to achieving a similar effect to the wide table 3.

[0118] The second mount portion 132 includes the engagement edge 66 that defines the opening 65 formed in the second side plate 122. When one direction along the short direction D1 is defined as the insertion direction K1, the wide table 3 includes the levers 34 and 35 that protrude from the table plate 31 in the insertion direction K1 and that are supported by the table plate 31. The levers 34 and 35 are inserted into the opening 65 in the insertion direction K1, and the levers 34 and 35 engage with the second mount portion 132, whereby the wide table 3 is attached to the bed 10. Compared with a configuration in which the levers 34 and 35 are provided at the bed 10 of the sewing machine 1 and the opening 65 is provided at the wide table 3, the engagement edge 66 of the sewing machine 1 contributes to the levers 34 and 35 not protruding from the bed 10 and not hindering sewing when the wide table 3 is not attached to the sewing machine 1. The engagement edge 68 of the sewing machine 1 also contributes to achieving a similar effect to the engagement edge 66 of the sewing machine 1.

[0119] The pillar 11 extends in the upper-lower direction and is connected to the bed 10. The second mount portion 132 is located between the first mount portion 130 and the pillar 11 in the longitudinal direction D2. The sewing machine 1 contributes to attaching the wide table 3 without interfering with the auxiliary device such as the embroidery device 140. The second mount portions 131 and 630 of the sewing machine 1 also contribute to achieving a similar effect to the second mount portion 132.

[0120] The bed 10 includes the cover 62 that closes the opening 65 in a state where the wide table 3 is not attached to the bed 10. The cover 62 of the sewing machine 1 contributes to reducing dust entering the inside of the bed 10 through the opening 65, for example. The cover 69 of the second mount portion 131 also contributes to achieving a similar effect to the cover 62 of the second mount portion 132.

[0121] The cover 62 of the second mount portion 132 is supported by the bed 10 so as to be pivotable between the closed position at which the cover 62 closes the opening 65 and the open position at which the cover 62 opens the opening 65. When the wide table 3 is attached to the bed 10, the cover 62 is pushed in the insertion direction K1 by the levers 34 and 35, and thereby pivots from the closed position to the open position. The cover 62 of the sewing machine 1 contributes to preventing the cover 62 from being lost, compared with a case where the cover 62 is detachable. The cover 62 of the sewing machine 1 contributes to switching the cover 62 between the closed position and the open position by a simple operation of pivoting the cover 62 between the closed position and the open position by inserting the levers 34 and 35. The cover 69 of the second mount portion 131 also contributes to achieving a similar effect to the cover 62 of the second mount portion 132.

[0122] In the wide table 7, the lever 84 includes the hook 85 that protrudes in the first direction N1. When one direction along the longitudinal direction D2 is the first direction N1 and the opposite direction is the second direction N2, the lever 84 is supported by the table plate 71 so as to be pivotable between the normal position and the attachment-detachment position where the hook 85 is located farther in the second direction N2 than at the normal position. After the lever 84 is inserted into the opening 67 in the insertion direction J1, the lever 84 pivots from the attachment-detachment position to the normal position, whereby the hook 85 engages with the second mount portion 131. The lever 84 of the sewing machine 1 contributes to performing the operation of engaging the lever 84 with the second mount portion 131 by a relatively simple operation of pivoting the lever 84 from the attachment-detachment position to the normal position. The lever 59 including the hook 535 of the sewing machine 1 also contributes to achieving a similar effect to the lever 84 of the sewing machine 1.

[0123] In the wide table 7, the lever 84 includes the inclined portion 86 located between the hook 85 and the end 83 of the lever 84 in the insertion direction J1. The inclined portion 86 is inclined in the longitudinal direction D2. The lever 84 is inserted into the opening 67 while the inclined portion 86 contacts the engagement edge 68, whereby pivots from the normal position to the attachment-detachment position. After the hook 85 of the lever 84 is inserted into the opening 67 in the insertion direction J1, the lever 84 pivots from the attachment-detachment position to the normal position, and thereby the hook 85 engages with the second mount portion 131. The inclined portion 86 of the sewing machine 1 contributes to performing the operation of pivoting the lever 84 from the normal position to the attachment-detachment position by a relatively simple operation of inserting the inclined portion 86 into the opening 67 while the inclined portion 86 contacts the engagement edge 68. The inclined portion 536, the first inclined portion 39, and the second inclined portion 38 of the sewing machine 1 also contribute to achieving a similar effect to the inclined portion 86 of the sewing machine 1.

[0124] The wide table 7 of the sewing machine 1 includes the lock release member 90. The lock release member 90 is connected to the lever 84, and is supported by the table plate 71 so as to be movable from the first position to the second position. When the lock release member 90 is moved from the first position to the second position in a state where the wide table 7 is attached to the bed 10, the lever 84 pivots from the normal position to the attachment-detachment position, and the engagement between the hook 85 and the second mount portion 131 is released. The lock release member 90 of the wide table 7 of the sewing machine 1 contributes to performing the operation of pivoting the lever 84 from the normal position to the attachment-detachment position by a relatively simple operation of moving the lock release member 90 from the first position to the second position. The lock release members 45 and 58 of the sewing machine 1 also contribute to achieving a similar effect to the lock release member 90.

[0125] The wide table 7 of the sewing machine 1 includes the spring 80 that urges the lock release member 90 in the direction from the second position toward the first position. The spring 80 of the sewing machine 1 contributes to moving the lock release member 90 from the second position to the first position by the urging force of the spring 80 after the operation of moving the lock release member 90 from the first position to the second position. The springs 30 and 550 of the sewing machine 1 also contribute to a similar effect.

[0126] The second mount portion 132 includes the engagement edge 66 that defines the opening 65 formed in the second side plate 122. One direction along the short direction D1 is defined as the insertion direction K1. One direction along the longitudinal direction D2 is defined as the first direction N1, and the opposite direction is defined as the second direction N2. The wide table 3 of the sewing machine 1 includes the second lever 34 and the first lever 35 that protrude from the table plate 31 in the insertion direction K1. The second lever 34 includes the second hook 36 that protrudes in the second direction N2. The second lever 34 is supported by the table plate 31 so as to be pivotable between the second normal position and the second attachment-detachment position where the second hook 36 is located farther in the first direction N1 than the second normal position. After the second lever 34 is inserted into the opening 65, the second lever 34 pivots from the second attachment-detachment position to the second normal position, whereby the second hook 36 engages with the second mount portion 132. The first lever 35 includes the first hook 37 that protrudes in the first direction N1. The first lever 35 is supported by the table plate 31 so as to be pivotable between the first normal position and the first attachment-detachment position where the first hook 37 is located farther in the second direction N2 than the first normal position. After the first lever 35 is inserted into the opening 65, the first lever 35 pivots from the first attachment-detachment position to the first normal position, whereby the first hook 37 engages with the second mount portion 132. The second lever 34 and the first lever 35 of the sewing machine 1 contribute to reliably attaching the wide table 3 to the second mount portion 132 of the bed 10, compared with a case where one lever engages with the second mount portion 132.

[0127] The opposite direction along the short direction D1 of the wide table 3 is referred to as the detachment direction K2. The wide table 3 has the second protrusion 461 and the first protrusion 462. When the second lever 34 is at the second normal position and the wide table 3 is moved in the second direction N2 with respect to the bed 10, the second protrusion 461 contacts the second detachment end portion 342 of the second lever 34 in the detachment direction K2. The second protrusion 461 is located farther in the second direction N2 than the second detachment end portion 342. When the first lever 35 is located at the first normal position and the wide table 3 is moved in the first direction N1 with respect to the bed 10, the first protrusion 462 contacts the first detachment end portion 352 of the first lever 35 in the detachment direction K2. The first protrusion 462 is located farther in the first direction N1 than the first detachment end portion 352. The second protrusion 461 of the sewing machine 1 contributes to preventing the second lever 34 from pivoting from the second normal position toward the second attachment-detachment position. The first protrusion 462 contributes to preventing the first lever 35 from pivoting from the first normal position toward the first attachment-detachment position.

[0128] The wide table 7 includes the legs 81 and 82. The leg 81 is connected to the table plate 71 so as to be pivotable about the pivot shaft 811 extending horizontally between the use position at which the leg 81 extends vertically and the storage position at which the leg 81 extends horizontally. The leg 82 is connected to the table plate 71 so as to be pivotable about the pivot shaft 821 extending horizontally between the use position at which the leg 82 extends vertically and the storage position at which the leg 82 extends horizontally. In a state where the legs 81 and 82 are at the storage position, the legs 81 and 82 contact the lever 84 or the lock release member 90, and the lock release member 90 is not movable from the first position to the second position. The legs 81 and 82 of the sewing machine 1 contribute to preventing the wide table 7 from being attached to the second mount portion 131 of the bed 10 in a state where the legs 81 and 82 are at the storage position. The wide table 500 of the first modification also achieves a similar effect. The legs 541 and 542 of the wide table 500 also contribute to a similar effect to the legs 81 and 82 of the wide table 7.

[0129] The sewing machine 1 includes the table sensor 20 that detects whether the wide table 7 is attached to the second mount portion 131, the table sensor 24 that detects whether the wide table 3 is attached to the second mount portion 132, the needle bar 6, and the CPU 75. In response to determining that the wide table 7 is attached to the second mount portion 131 and the wide table 3 is attached to the second mount portion 132 based on the detection results of the table sensors 20 and 24 (S6: YES), the CPU 75 drives the needle bar 6 in the upper-lower direction at the second speed that is faster than the first speed which is used when at least one wide table is not attached to the second mount portions 131 and 132 (S7 and S9). The CPU 75 of the sewing machine 1 contributes to, when the wide tables 3 and 7 are attached, automatically switching the sewing speed considering that the sewing workpiece is stably supported, compared with a case where at least the wide table 3 or 7 is not attached.

[0130] The sewing machine 1 includes the table sensors 20 and 24, the embroidery device 140, the frame sensor 22, the needle bar 6, and the CPU 75. The table sensor 20 detects whether the wide table 7 is attached to the second mount portion 131. The table sensor 24 detects whether the wide table 3 is attached to the second mount portion 132. The embroidery device 140 is an auxiliary device that is attached to the first mount portion 130 of the bed 10. The embroidery device 140 includes the holder 143 to which the embroidery frame 150 is attachable, the holder 143 being movable horizontally. The frame sensor 22 detects the type of the embroidery frame attached to the holder 143. In a state where the wide table 3 is attached to the second mount portion 132, the second extension surfaces 32 and 72, the bed surface 110, and the first extension surface 139 are located below the embroidery frame 150. The CPU 75 acquires the detection result of the frame sensor 22 and, when the embroidery frame 150 of the particular size is attached (S3: YES), performs the notification process of notifying that the wide table 7 is to be attached the second mount portion 131 and the wide table 3 is to be attached to the second mount portion 132 (S4). When it is determined that the embroidery frame 150 of the particular size is attached based on the detection result of the frame sensor 22 and that the corresponding wide tables 7 and 3 are not attached to the second mount portions 131 and 132 based on the detection results of the table sensors 20 and 24 (S6: NO), the CPU 75 performs the warning process of outputting a warning (S8). The CPU 75 of the sewing machine 1 contributes to increasing the possibility that sewing is performed under a condition that the wide tables 3 and 7 support the embroidery frame 150 when the embroidery frame 150 is bent by the weight of the sewing workpiece in a case where the embroidery frame 150 that is relatively large is attached to the holder 143.

[0131] The embroidery device 140 is an auxiliary device that is attached to the first mount portion 130 of the bed 10. The embroidery device 140 includes the holder 143 to which the embroidery frame 150 is attachable, the holder 143 being movable horizontally. In a state where the wide table 3 is attached to the second mount portion 132, the second extension surface 32, the bed surface 110, and the first extension surface 139 are located below the embroidery frame 150. When the embroidery device 140 is attached to the sewing machine 1 and a sewing workpiece larger than the bed surface 110 is sewn, the wide table 3 of the sewing machine 1 supports the embroidery frame that holds the sewing workpiece together with the bed 10, and thus contributes to improving the ease of sewing by the sewing machine 1.

[0132] The second mount portion 630 of the sewing machine 1 of the second modification includes the first magnets 631 and 632. The table plate 601 of the wide table 600 includes the second magnets 606 and 607, and the wide table 600 is attached to the bed 10 by magnetic force between the first magnets 631 and 632 and the second magnets 606 and 607. The second mount portion 630 of the sewing machine 1 contributes to simplifying the configuration and operation for attaching the wide table 600.

[0133] The wide table 7 that is attached to the sewing machine 1 includes the table plate 71, the legs 81 and 82, the lever 84, the hook 85, and the lock release member 90. The table plate 71 has the second extension surface 72 which is a table surface extending horizontally. The legs 81 and 82 are connected to the table plate 71. The lever 84 protrudes from the table plate 71 in the insertion direction J1 which is one direction along the short direction D1 of the bed surface 110 of the sewing machine 1 that extends horizontally. When one direction along the longitudinal direction D2 of the bed surface 110 is defined as the first direction N1 and the opposite direction is defined as the second direction N2, the hook 85 protrudes in the first direction N1. The lever 84 is supported by the table plate 71 so as to be pivotable between the normal position and the attachment-detachment position where the hook 85 is located farther in the second direction N2 than the normal position. The opening 67 is formed in the second side plate 121 that extends downward from the outer periphery 19 of the bed surface 110 and that crosses the short direction D1. The lever 84 is inserted into the opening 67 in the insertion direction J1 and then pivots from the attachment-detachment position to the normal position, whereby the hook 85 engages with the second mount portion 131 of the sewing machine 1 that includes the engagement edge 68 that defines the opening 67. The lock release member 90 is connected to the lever 84, and is supported by the table plate 71 so as to be pivotable from the first position to the second position. When the lock release member 90 is moved from the first position to the second position, the lock release member 90 causes the lever 84 to pivot from the normal position to the attachment-detachment position, and releases the engagement between the hook 85 and the second mount portion 131 of the sewing machine 1. In a case where a sewing workpiece that is larger than the bed surface 110 is sewn, by attaching the wide table 7 to the bed 10, the wide table 7 of the sewing machine 1 supports the sewing workpiece together with the bed 10, and thus the wide table 7 contributes to improving the ease of sewing by the sewing machine 1. Since the wide table 7 of the sewing machine 1 is detachably attached to the bed 10, it is switchable whether to use the wide table 7 depending on the size of the sewing workpiece. Thus, the wide table 7 of the sewing machine 1 achieves both the compactness of the sewing machine 1 and the improvement in the ease of sewing a relatively large sewing workpiece, as compared with a case where the wide table 7 is not detachable from the bed 10. The lever 84 of the sewing machine 1 contributes to performing the operation of engaging the lever 84 and the second mount portion 131 by a relatively simple operation of pivoting the lever 84 from the attachment-detachment position to the normal position. The lock release member 90 of the sewing machine 1 contributes to performing the operation of pivoting the lever 84 from the normal position to the attachment-detachment position by a relatively simple operation of moving the lock release member 90 from the first position to the second position. The wide tables 3 and 500 also contribute to a similar effect.

The cover 69 of the second mount portion 131 and the cover 62 of the second mount portion 132 may be detachably attached to the corresponding engagement edges.

[0137] At least the second mount portion 131 or 132 may be disposed leftward of the first mount portion 130 in the longitudinal direction D2. The first lever 35, the second lever 34, and the levers 59 and 84 may be appropriately changed in shape and arrangement, and for example, may be disposed farther in the second direction N2 than the center in the longitudinal direction D2 of the corresponding table plate. For example, the shape and arrangement of the hook 85, the first hook 37, and the second hook 36 may be appropriately changed, or may be appropriately omitted. The first lever 35 and the second lever 34 may not be bilaterally symmetrical to each other. The shapes of the first inclined portion 39, the second inclined portion 38, and the inclined portions 86 and 536 may be appropriately changed or may be omitted. The shapes and the arrangements of the second protrusion 461 and the first protrusion 462 may be appropriately changed or may be omitted. The wide table 7 may include a protrusion that contacts an end portion of the lever 84 in the detachment direction J2 when the lever 84 is at the normal position and the wide table 7 is moved in the second direction N2 with respect to the bed 10, the protrusion protruding downward at a position farther in the second direction N2 than the end portion. The wide table 500 may also include a similar protrusion.

[0138] The shape, number, and arrangement of the second magnets 606 and 607 may be changed as appropriate. The shape, number, and arrangement of the first magnets 631 and 632 may be changed as appropriate. For example, the number of the second magnets may be one, or three or more. In a case where the wide table includes a plurality of second magnets, the magnetic fields generated by the adjacent second magnets may be different from each other or may be the same as each other. The same applies to the first magnets provided at the sewing machine 1. Each of the short direction D1, the longitudinal direction D2, the first direction N1, and the second direction N2 may be changed in accordance with the configuration of the sewing machine 1.

[0139] The program including the command for executing the main process of FIG. 20 may be stored in a memory of each apparatus by the time the CPU 75 executes the program. Thus, the method of acquiring the program, the path of acquiring the program, and the device that stores the program may be changed as appropriate. The program executed by the CPU 75 may be received from another apparatus via a cable or wireless communication and stored in a memory such as a storage. The other apparatuses include, for example, a PC and a server connected via a network.

[0140] The steps of the main process are not limited to the example of being executed by the CPU 75, and a part or all of the steps may be executed by another electronic device (for example, an ASIC). The steps of the main process may be processed in a distributed manner by a plurality of electronic devices (for example, a plurality of CPUs). The order of the steps of the main process may be changed, and steps may be omitted or added as necessary. The following changes may be made to the main process as appropriate.

[0141] In the sewing machine 1, a part or all of the main process may be omitted. The sewing machine 1 may acquire the type of the embroidery frame that is attached to the holder 143 based on an input result of the user in S2. In the sewing machine 1, the CPU 75 may output a message to an external device in at least S4 or S8, and the message may be output by the external device. The CPU 75 may output a message or a warning by sound or voice in at least S4 or S8. At least S4 or S8 may be omitted, and the sewing may be stopped after the processing of S8. The CPU 75 may be configured not to output a warning when it is detected that at least the wide table 3 or 7 is attached. The processing of S3 may be omitted, and the CPU 75 may perform control such that sewing is performed at the second speed when it is detected that at least the wide table 3 or 7 is attached, regardless of the size of the embroidery frame attached to the holder 143. The CPU 75 may change the sewing speed such that the larger the area on which the sewing workpiece is placed, the faster the sewing speed. More specifically, the CPU 75 may change the sewing speed among a case where the wide table 3 is attached, a case where the wide table 7 is attached, and a case where both the wide tables 3 and 7 are attached.

[0142] The above modifications may be combined as appropriate. In addition to the combinations exemplified above, aspects combined with each other without departing from the scope of the present disclosure and without causing contradiction are also included in the scope of the present disclosure.
