The thread cutting device shown in FIG. 1 has a movable blade 212 which rotates in an upright plane above the inner hook. The blade 212 plows the upper thread 223 and the lower thread about the hooks 202 and cuts the pivot movement 202. T · / / * é é é é é
As. shown in Fig. 28, the base 21C of the movable knife 212 is attached to a drive shaft 208 that rotates under the action of a drive source not shown, wherein the movable knife 212 is attached to the base 210 of the movable knife 212.
When the drive shaft 208 is rotated, the movable knife 212 performs a reciprocating rotational motion over the hook. 214, wherein the drive shaft 208 forms an ace of rotation. Depending on this rotation, the upper portion of the movable knife 212 engages the lower n-206 as shown in Fig. 29, and pulls the lower n-206. thread 206 towards the fixed blade 216 (cutting knife). If the cutting edge 218 of the flexible knife 212 is flush with the solids 216, the lower thread 206 is cut at T,
At the same time, the end of the bottom thread 206 on the housing side is cut off by a lower thread clamping spring 220 and is held to drive further sutures.

However, in the sewing machine described in JP 7-289 765 A, there is insufficient space under the stitch plate 228 to contact the tips of the movable knife 212 and the fixed knife 216. Thus, the position of the thread cutting in which the threads are cut through cooperation is a movable knife 212 and a fixed knife 216, positioned outside the wall boa. Consequently, the residual length L of the yarn remaining on the side of the sewn article is too long. There is therefore the problem of not having to spend considerable time and effort on subsequent processing, such as pulling out the thread, resulting in a reduction in productivity. 4 »t * * * ·· · · * · * * * * · · · I • · · · * * · · · · · · *

Since the n is 9 m and the shape of the boundary, Z 7 V W Z Z can be used. much more than a conventional knife blade, for example, is formed in a plate weld. Subsequently it is possible to trim the stronger " thread, than conventional thread, 5 in cooperation with the cutting knife 2. It is also possible to increase the possibility of the thread used in sewing. The upper thread release path 9a arranged on the movable blade 9 prevents the cutter end of the upper thread bv1 from being held by the movable knife 9. As a result, the upper thread may be left remaining at 4: smoothly. átnv ρί cut the top. This makes it easy to remove the stitched fabric, increasing productivity. Since the tip of the movable blade 9 and the tip of the outer blade of the knife 9 are adjusted so that the same sky is less than 30 °, the movable knife 9 can enter the upper thread loop by pressing the finished thread Ti or a lower thread T2 in the direction of the perspiration sweat of the knife 9.
Thus, it is possible to smoothly perform the catching operation in the yarn catching position. As a result, the reliability of the sewing machine operation can be improved. i · «
