[0030] Hereinafter, the present invention is in detail disclosed with reference to the attached drawings.

[0031] An electronically controlled pattern sewing machine S according to the present invention includes a jig 100 as known, a marking part 200 for marking a sewing line on a fabric, a sensing part 300 for sensing coordinates of the sewing line, a sensed coordinate storing part 400, a controller 500, a function setting part 600, and an operation panel box 700.

[0032] In this case, the jig 100 serves to press the fabric so that the fabric is located at an accurate position, without any movement, during a sewing operation, and further, the jig 100 has a pattern-shaped through hole formed thereon so that a needle of the electronically controlled pattern sewing machine S performs the sewing operation along the sewing line of the fabric, without having any inhibition.

[0033] Further, the marking part 200 serves to mark the sewing line along a periphery of the pattern-shaped through hole formed on the jig 100.

[0034] Also, the sensing part 300 serves to sense the coordinates of the sewing line marked by the marking part 200. At this time, the sensing part 300 is provided to various shapes through various methods.

[0035] For example, the sensing part 300 includes a light emitter 310 for irradiating light on the fabric above the fabric, a light receiver 320 for receiving the light irradiated from the light emitter 310 and then reflected on the fabric, and a pattern coordinate operator 330 for calculating and operating the coordinates of the light reflected on the sewing line or the periphery of the through hole of the jig 100 from the received light to the light receiver 320.

[0036] In this case, the sensed coordinate storing part 400 serves to store the coordinates of each point of the sewing line sensed by the sensing part 300.

[0037] Also, the controller 500 automatically converts the coordinates of each point of the sewing line sensed by the sensing part 300 and then stored in the sensed coordinate storing part 400 into sewing coordinates adequate to the electronically controlled pattern sewing machine S.

[0038] In this case, the function setting part 600 serves to set various sewing functions, such as a run function, a speed function, a stitch-length function, a trimmer function, a jump function, and so on, on a portion to be sewn according to the sewing coordinates converted by the controller 500.

[0039] Further, the operation panel box 700 serves to control the movements of the needle of the electronically controlled pattern sewing machine S according to the sewing coordinates converted adequately to the electronically controlled pattern sewing machine S, so that the needle operates according to the set various functions.

[0040] Under the above-mentioned configuration, now, an explanation on an operating procedure of the electronically controlled pattern sewing machine S according to the present invention will be given.

[0041] First, the jig 100 made separately from the electronically controlled pattern sewing machine S is clamped to allow the fabric to be supported thereagainst (S100). The jig 100 serves to accurately locate the fabric on the electronically controlled pattern sewing machine S, while pressurizing the fabric.

[0042] Next, the coordinates of the sewing line to be sewn on the fabric clamped by the jig 100 are sensed by means of the sensing part 300 (S120). To do this, light is irradiated onto the fabric above the jig 100 through the light emitter 310 of the sensing part 300 (S122), and after that, the light reflected after the irradiation of the light emitter 310 is received by the light receiver 320 of the sensing part 300 (S124).

[0043] In detail, the light irradiated from the light emitter 310 passes through the pattern-shaped through hole formed on the jig 100 and is changed, and the light at the changed position is received by the light receiver 320. Otherwise, light, which is reflected on the line marked (S110) along the through hole of the jig 100 by means of the marking part 200 like a pen, can be received. The received light is operated to coordinates X and Y of each point of the sewing line by means of the pattern coordinate operator 330 of the sensing part 300 (S126), and the coordinates are stored in the sensed coordinate storing part 400 (S130).

[0044] The stored coordinates are automatically converted into the sewing coordinates adequate to the electronically controlled pattern sewing machine S by means of the controller 500 (S140).

[0045] Further, various sewing functions, such as a run function, a speed function, a stitch-length function, a trimmer function, a jump function, and so on, are set by means of the function setting part 600 on the converted sewing coordinates (S150), and next, the electronically controlled pattern sewing machine S is operated by means of the operation panel box 700 to perform the sewing operation according to the various sewing functions set by the function setting part 600 (S160).

[0046] As described above, the electronically controlled pattern sewing machine according to the present invention can automatically detect and program the coordinates of the sewing line of the fabric even if the coordinates of the sewing line is not set manually one by one or even if they are not programmed by the CAD or punching device, so that there is no high-priced program, time and cost are drastically reduced, and the operation is performed by the manipulation of even unskilled workers.
