Abstract
PURPOSE: To reduce costs and to improve functions by providing a reflection part positioned obliquely to a light incident direction from a fiber for light transmission on a reflector and providing the fiber for the light transmission and the fiber for receiving reflected light to be a needle position signal on the reflector. CONSTITUTION: A photoelectric conversion module part 8 is composed of one light emitting element 20, one fiber 13 for the light transmission, two light receiving elements 21 and 22, the respectively corresponding two fibers 14 and 15 for light reception, a signal processing circuit 24 and a connector 9 for power source and signal connection. Also, a detection part 6 is composed of the reflectors 17 and 18 attached to a shaft engaged with a sewing machine shaft 5 to be rotated and provided with the reflection part obliquely to the light incident direction from the fiber 13 for the light transmission, the one fiber 13 for the light transmission supported by an optical fiber supporter 16 for making light be incident on the reflector and the fibers 14 and 15 for the light reception for receiving the reflected light to be a needle upper position or needle lower position signal. Then, by an optical fiber cable 7 containing the fibers for the light transmission and reception, the module part 8 and the detection part 6 are connected.
