PURPOSE:To reduce the occurrence of faults such as a contact defect, by performing the release of a clutch, which is connected to a motor, due to position detection of a moving material and the transmission of an output voltage to the next-stage circuit by one contact. CONSTITUTION:A moving material T is moved by a motor M and a clutch CL; and in the home position, the clutch CL is released by the operation of a detector X, and an output voltage is transmitted to the next-stage circuit. The series circuit of resistances R1, R2 and R3 is connected in parallel to the series circuit of the detector X and the clutch CL. The base of a transistor TR is connected to the connection point between resistances R1 and R2. The series circuit of a Zener diode ZD and a diode D is connected in parallel to the clutch CL. Thus, the release of the clutch CL and the transmission of the output voltage to the next-stage circuit are performed by only one contact of the detector X. |
