Title: Projector for photoelectric switch
Inventor: TANIGAWA KIYOSHI
IPC: H03K17/78
Filed: 1988-06-22
Abstract: PURPOSE:To evade delay in start or delay of a projector by connecting a collector/emitter of a voltage detection transistor(Tr) between a base and emitter of an output Tr and applying a power voltage to a base of the voltage detection Tr. CONSTITUTION:The collector and emitter of the voltage detection Tr 15 are connected between the base and emitter of the output Tr 10 and the voltage of the power supply 1 is applied to the base. When the switch 2 is closed, the Tr 15 is turned on, the Tr 10 is turned off and no light emitting diode 8 is operated. When the switch 2 is opened and the power supply 1 is interrupted, the Tr 15 is turned off. Thus, since the Tr 10 is turned on/off by a pulse train from a pulse generating circuit 7, a light emitting diode 8 is lighted. Since the power interruption 1 is short in time, the power is supplied from a smoothing capacitor 5. In the case of selecting the static capacitance of the capacitor 5 largely, the voltage change is decreased and the projecting time is extended.
