ABSTRACT:
A detector is provided for a sewing machine wherein light transmitting/shielding discs are mounted coaxially on a shaft of the sewing machine and sandwiched between light receiving and light transmitting optical fibers positioned along opposite side portions of the disc assembly and leading to a processing module section. The detector is able to detect a plurality of positional settings of the sewing machine as well as additional settings without imposing undue stress on the light transmitting optical fibers since the optical fibers remain linear. A power indicating light, connected to the processing module section via an optical fiber, ensures that there is minimal electrical interference with the operation of the detector.
