Document Type and Number:
Japanese Patent JP09273068
Kind Code:
A
Abstract:

To accomplish fabric end detection without any manual preparation for the fabric end detection.

The beams reflecting from detection ranges 191 and 201 on a woven fabric are received respectively by photodetectors 19 and 20 and the photodetectors convert the received beam to electric signals. The whotodetectors 19 and 20 output the converted electric signals respectively through current- voltage conversion circuit 28 and, 29 to a signal-processing circuit board for the fabric end detection 22. The signal-processing circuit board for the fabric end detection compares the input electric signal value with the previously set signal level to judge the fabric end detection.
