[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sewing machine suitable for sewing Japanese clothes.

[0002]

2. Description of the Related Art When sewing Japanese clothes by hand, as shown in FIG. 5, for example, a case where a front body 1 and a back body 2 are sewn will be described. So that the longitudinal direction extends laterally with respect to the sewer, and the ears 3 on the opposite side (hereinafter referred to as the opposite side) but not on the front side of the sewer in the two overlapped fabrics. Is attached to the pulling device 4 and sewn by moving the needle from the right end to the left, and sewn from the hem 5 side of the kimono to the upper side (neck side). It is.

In the case where the fabric has a pattern, the sewing is performed while confirming whether the patterns 6 of both fabrics match during the sewing. As shown in FIGS. 6 and 7, the operation at that time is confirmed by rolling up the upper cloth of both cloths, that is, the front body 1 from the near side to the opposite side, and applying the covering 7 to the front body 1. Things.

[0004] Therefore, by sewing the overlapped fabric as described above, the operation of pattern matching can be performed easily and reliably. Therefore, when learning the technique of tailoring kimono, a right-handed person can use a hand movement. There was no problem, but left-handed people had difficulty coaching right-handed people.

[0005]

When the above-mentioned sewing is sewn with a normal sewing machine, there are the following various problems.

As shown in FIG. 8, the ordinary sewing machine 8 includes an upper thread driving device 9 having a needle bar and a lower thread driving device (not shown) having a shuttle, and a frame 10 having a substantially C shape.
The sewing machine 8 is arranged side by side,
That is, the cloth is sent from the right side to the left side and arranged so as to be sewn. Then, as described above, the cloth which is piled up with the front body 1 up and the back body 2 down, most of which is the C-shaped frame 10 of the sewing machine 8. When the ear 3 is sewn on the front side, the hem 5 of the layered fabric is sewn by normal stitching from the hem 5 side. Therefore, there is a problem that normal sewing is not performed due to passing through the inside, and furthermore, when pattern matching is performed during sewing, since the sewn portion 11 is on the near side, the front body Is turned up from the opposite side, and at that time, the eyes lean out of the face and look into the near side, and there is a problem that it is hard to confirm and lacks accuracy.

On the other hand, as shown in FIG. 9, most of the dough in which the back body 2 is placed on the back, the back body 1 is placed on the bottom and the most part of the fabric is You can sew by normal stitching even if you arrange it outside the pocket and meet the ear 3 on the opposite side, but since the piled fabric is upside down, when matching the pattern 6, the front body on the back side It is difficult to hang the garment 7 around and watch it, and it cannot be used for sewing Japanese clothes.

Then, by reversing the driving of the sewing machine 8 described above, as shown in FIG. 10, the cloth is sent from the left to the right, and the thread is sewn from the right to the left. The pattern matching operation is also easy, but the sewing stitch is reversely driven, so that the stitch becomes a hitch stitch, and the seam is disturbed, which is not suitable for sewing Japanese clothes.

An object of the present invention is to provide a sewing machine which eliminates various difficulties and drawbacks caused by sewing, enables sewing similar to hand sewing by using sewing machines, and can sew Japanese clothes by using normal stitches. .

A solution according to the present invention is to maintain a pair of belts, on which a cloth to be sewn is placed and transported to one side, at a distance horizontally and parallel to each other so that both belts have the same speed. A feed means running from the left side to the right side with one side orthogonal to the longitudinal direction of the belt as a front face, a needle thread driving means provided above the feed means, And a lower thread driving means provided at a lower portion of the means, wherein the needle bar of the upper thread driving means faces the interval between the two belts, and the sewing machine needle is directed to the needle bar, and the hollow portion thereof faces the front side. And the shuttle of the lower thread drive means is provided so as to be rotatable counterclockwise toward the side opposite to the front with respect to the sewing machine needle.

In addition to the above-mentioned solution, there is provided a projection device for projecting visible rays from above, along an imaginary line along the longitudinal direction of the belt around the point where the sewing needle descends within the interval between the two belts. It is characterized in that it is provided.

[0012]

With the above-described sewing machine, the sewing manufacturer stands at a position perpendicular to the running direction of the belt, with the upper side of the running direction of the belt on the left side and the lower side on the right side. With the ears to be sewn on the opposite side and at the interval between both belts.If there is projection means, the sewing position by visible light is displayed on the surface of the cloth to be sewn. Then, the upper thread driving means, the lower thread driving means, and the feeding means are driven, and the sewing manufacturer presses the sewn cloth against both belts, so that the sewn cloth is sent from the left to the right, while the sewn cloth is sent from the right. It is sewn to the left, the seam is sewn with normal normal stitches, and it is the same as conventional hand sewing, and the pattern matching operation in the middle can be inspected as well as the conventional case .

In addition, during sewing, the sewing is not limited to straight stitching but is often performed with bending in the middle. In the case of hand sewing, the position where the bending is performed is marked. Can be sewn directly to the belt without any need for marking if the holding position is measured and held down.
