DESCRIPTION OF EMBODIMENT

[0041] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In this specification, the vertical direction visually recognized in FIG. 1 is defined as the vertical direction of a file, and the horizontal direction visually recognized similarly is defined as the horizontal direction of a file, unless otherwise stated.

[0042] A file 1 illustrated in FIG. 1 files a document 5 by overlapping a document protective sheet 4 on a base plate 2, sandwiching left ends of the document protective sheet and the base plate over the substantially whole vertical length by a slider 3 with elastic force of the slider 3, and further moving the slider 3 to a position where the document 5 is sandwiched in a state where the document 5 is inserted between the base plate 2 and the document protective sheet 4. The position where the slider 3 is disposed is not limited to the left end, and may be a right end, an upper end, or a lower end of the base plate. Additionally, the number of the sliders 3 to be disposed is not limited to 1, and a plurality of the sliders may be disposed.

[0043] As illustrated in FIG. 2 and FIG. 3, in the base plate 2, cutting lines 20 are provided toward the vertical center of the base plate 2 from respective upper and lower ends near two corner parts which are upper and lower ends of a left end, so that lug pieces 21 having distal ends 211 that are edges located on the same virtual line as upper and lower edges of the base plate are formed, folding lines 213 that horizontally extend toward the left ends of the base plate 2 from ends near the vertical center of the base plate 2 of the cutting lines 20 are further provided, the lug pieces 21 are folded toward a surface opposite to a surface facing a pressing plate 34 of the slider 3 described below and the document protective sheet 4, with the folding lines 213 as base line, so that regulating wall units 21 that are erected to the base plate 2 are formed.

[0044] In each of the regulating wall units 21, when the distal end 211 is defined as a first side, a second end 212, and a contact part 214 that is an edge of the regulating wall unit 21 separated from the base plate by the cutting line 20 are defined as a second side and a fourth side, respectively, and the folding line 213 located at a position facing the distal end 211 is defined as a third side, virtual lines on the same lines as the first, second, third, and fourth sides are connected, and a virtual quadrangle is presented. However, as long as the lug pieces 21 are folded with the folding lines 213 as base lines, and the regulating wall units 21 are formed, the shape is not limited to the above shape. For example, any of or all of the distal ends 211, the second ends 212, and the contact parts 214 may be curved.

[0045] Furthermore, the second ends 212 may be located on the same virtual line as the left end of the base plate 2 in a state where the lug pieces 21 are not folded with the folding lines 213 as base lines, or the second ends 212 may be located at positions closer to the right than the proximal ends. Similarly, the distal ends 211 may be located on the same virtual line as the upper and lower ends of the base plate 2, or the distal ends 211 may be located at positions closer to vertical inside than the proximal ends.

[0046] As illustrated in FIG. 4, when the slider 3 and the base plate 2 are combined, the regulating wall units 21 are located so as to be surrounded by cutout parts 32, any of ends forming the cutout parts 32 comes into contact with the regulating wall units 21, or continues to be located near the regulating wall units 21, so that movement of the slider 3 to the base plate 2 is regulated.

[0047] More specifically, in the slider 3, the cutout parts 32 formed by cutting out the slider toward vertical inside are formed at the upper and lower ends, a part of one of ends forming each of the cutout parts 32 comes into contact with the regulating wall unit 21, or continues to be located near the regulating wall unit 21 in a state where the slider is spliced to the base plate 2, so that the one of ends forms orthogonal movement preventing units 321 that regulate movement of the slider 3 in the vertical direction, namely in the direction orthogonal to the advancing/retreating direction.

[0048] When the slider 3 is located at a position where the document 5 is sandwiched illustrated in FIG. 5A, the document 5 is filed. Then, when the slider moves in the retreating direction from the above position (to the left in FIG. 1, to the right in FIG. 5), the one end of the ends forming the cutout parts 32 reaches such a position as to come into contact with the contact part 214 that is one end of the regulating wall unit 21, as illustrated in FIG. 5B, so that passing of the slider over a maximum pulling-out position, and further movement of the slider in the retreating direction are regulated. That is, the one end forms a retreat movement preventing unit 322, and an end facing the retreat movement preventing units 322 forms a third end 323.

[0049] Thus, the regulating wall units 21 come into contact with the orthogonal movement preventing units 321 or continues to be located near the orthogonal movement preventing units 321, so that the vertical movement of the slider 3 is regulated, and when the slider reaches the maximum pulling-out position, the contact parts 214 come into contact with the retreat movement preventing units 322, so that the movement of the slider in the retreating direction is regulated.

[0050] The regulating wall units 21 are thus formed with respect to the cutout parts 32, and therefore when the horizontal lengths of the regulating wall units 21 are set to be short, a movement range of the slider 3 is increased. However, the areas of the regulating wall units 21 become small due to such short lengths, and therefore durability is low. When the horizontal lengths of the regulating wall units 21 are set to be long, the movement range of the slider 3 is shortened. However, the areas of the regulating wall units 21 can be increased, and therefore durability is high. That is, the horizontal lengths of the regulating wall units 21 may be determined in accordance with various conditions such as the size of a file, and the number of sheets of the document 5 to be stored.

[0051] As illustrated in FIG. 6, the slider 3 has a movable plate 31 that is located at a lower part in this figure, and moves on a surface of the base plate 2, a rising plate 33 that extends upward in this figure from the movable plate 31, and the pressing plate 34 that extends from the rising plate 33 to the left (to the right in FIG. 1) visually recognized in this figure, and is integrally formed of resin having suitable elasticity, has a substantially U-shaped cross-section, and sandwiches the base plate 2 and the document protective sheet 4 placed on the base plate 2 in order to prevent damage resulting from direct contact of the pressing plate 34 and the document 5 between the movable plate 31 and the pressing plate 34.

[0052] As illustrated in FIG. 1 and FIG. 4, the whole vertical length of the slider 3 is set to be substantially equal to the whole vertical length of the base plate 2. As illustrated in FIG. 7A, when the slider 3 moves in such a direction as to come close to the end of the base plate 2, and the third ends 323 come into contact with the regulating wall units 21 or the slider 3 reaches a position where the end of the base plate 2 comes into contact with an inner surface of the rising plate 33, namely a maximum pushing-in position, the slider 3 presses the document protective sheet 4 in the direction in which the document protective sheet 4 comes close to the base plate 2, so that the slider 3 holds the document 5 disposed between the base plate 2 and the document protective sheet 4. As illustrated in FIG. 7B, when the slider 3 moves in such a direction so as to be separated from the end of the base plate 2 to reach a position where the contact parts 214 come into contact with the retreat movement preventing units 322, the slider 3 is separated from a position where the base plate 2, the document protective sheet 4, and the document 5 are overlapped with each other to release the pressing at the position, so that the document 5 is not held.

[0053] More preferably, in a state where the slider 3 holds the document 5, illustrated in the FIG. 7A, the base plate 2 and the document protective sheet 4 may be sandwiched between a pressing unit 35 provided inside the slider 3 and the movable plate 31 at the end.

[0054] In a case where the regulating wall units 21 are provided in the corner parts of the base plate 2, the third ends 323 of the slider 3 come into contact with the second ends 212 of the regulating wall units 21, so that the position is set to the maximum pushing-in position, the single cutting line 20 only needs to be provided near each of the upper and lower corner parts in order to form the regulating wall units 21, and manufacturing efficiency is suitable. However, in a case where such a mode is employed, each time the slider 3 reaches the maximum pushing-in position, force is applied to the regulating wall units 21. When this is considered, the horizontal lengths are set to be long in consideration of the durability of the regulating wall units 21, preferably.

[0055] On the other hand, although not illustrated, in a case where the regulating wall units 21 are provided at positions closer to the horizontal center than the corner parts of the base plate 2 (positions closer to the left in FIG. 5), in order to form the regulating wall units 21, the two cutting lines 20 for forming the second end 212 and the contact part 214 need to be arranged side by side in the horizontal direction near the corner part of each of the upper and lower corners. Consequently, the position where the end of the base plate 2 comes into contact with the inner surface of the rising plate 33 becomes the maximum pushing-in position, and therefore the third ends 323 do not come into contact with the second ends 212. In this condition, durability of the regulating wall units 21 does not need to be considered.

[0056] That is, if it is considered that manufacturing efficiency is important, the regulating wall units 21 are preferably provided in the corner parts of the base plate 2, and if it is considered that a constitution in which the regulating wall units 21 are unlikely to be deteriorated is important, the regulating wall units 21 are preferably formed at positions closer to the horizontal center than the corner parts of the base plate 2. These may be selected in accordance with various conditions such as the size of a file, and the number of sheets of the document 5 to be stored.

[0057] In each of the regulating wall units 21, the first side forming the distal end 211 may be longer than the folding line 213, and the second end 212 and the contact part 214 that are in contact with these may not form parallel relation, so that at least the contact part 214 may not form a right angle with the distal end 211, and a right angle with the folding line 213. In a case where the distal end 211 and the folding line 213 are parallel to each other, the regulating wall unit 21 may be provided so as to form a virtual trapezoid when four virtual lines located on the same lines as the second end 212, contact part 214, distal end 211, and folding line 213 are connected.

[0058] With such a formation, as illustrated in FIG. 8A, when the slider 3 moves in a state where the slider is separated from the base plate 2 in the vertical direction visually recognized in this figure, the contact parts 214 come into contact with the retreat movement preventing units 322. Thereafter, when the slider receives force for further moving in the retreating direction (to the right in this figure), the movable plate 31 moves so as to approach the base plate 2 with upward movement of the retreat movement preventing units 322 in this figure along the inclined contact parts 214. When this action is continued, the slider 3 comes into contact with the base plate 2 as illustrated in FIG. 8B.

[0059] In addition, when the file is in a non-holding state illustrated in FIG. 7B and FIG. 8, in order to separate the slider 3 from the base plate 2 in the vertical direction visually recognized in these figures, the slider needs to get over inclinations formed by the contact parts 214 to lower the movable plate 31. That is, in a case where the contact parts 214 are inclined, when the file is in the non-holding state, the slider 3 is unlikely to be detached from the base plate 2.

[0060] The present invention is capable of regulating movement of the slider 3 in the direction orthogonal to the movement advancing/retreating direction, or movement of the slider 3 in the retreating direction beyond the maximum pulling-out position, only by providing the cutout parts 32 without connection of another member for regulating the above movement by welding or adhesion.

[0061] Additionally, the present invention is capable of regulating movement of the slider 3 in the direction orthogonal to the movement advancing/retreating direction, or movement of the slider 3 in the retreating direction beyond the maximum pulling-out position, only by providing the lug pieces 21 at the corner parts or near the corner parts of the base plate 2 and folding the lug pieces 21 without connecting, to the base plate 2, another member for regulating the above movement by welding or adhesion.
