ABSTRACT:
The present invention is a signal detecting device, which includes a casing, drive unit, feeding strip and transmitting strip. The signal detecting section of transmitting strip coincides with the movement path of the transmitting section of the conducting disc, and the transmitting strip is also fitted with some spacing grooves and flanges. Thus, the conducting signal will occur if the transmitting section of the conducting disc is aligned with the flanges or grooves. So, digital signal output is guaranteed to significantly improve the section detecting accuracy. Based upon the detecting unit, it is possible to ensure real-time error detection and automatic correction or resetting.
