1. The jig pattern sensor checks if the number of the program read from the floppy disk and the number of the sewing

clamp set to the machine are identical.

2. The jig pattern sensor consists of six photo sensors. This sensor checks 64 jig patterns by combining the slit plates on

the sewing clamp.

3. When DIP switch B-1 on the main PCB is set to on, the machine can sew regardless of the signal of the jig pattern

sensor. (Set the DIP switch to off in usual operation. It is set off for shipping.)
