Abstract

PURPOSE:To facilitate processing of the signal at the next stage and then increasing the reply speed of the light reception signal by obtaining the signal synchronized with the reception signal by the use of both the 1st and 2nd oscillators, thus securing an application of a photoelectic switch to both the transmitting and reflecting types. CONSTITUTION:The pulse having a certain cycle is oscillated by the 1st oscillator 1, and the signal synchronized with the cycle of the output signal of the oscillator 1 is projected to the photodetector 3 from the projector element 2. The signal received a the photodetector 3 is applied to the 2nd oscillator 4 after the DC amplification through the DC amplifying circuit 13. And in case the reception signal exists, the oscillation is given in synchronization with the oscillating cycle of the oscillator 1; while in case no reception signal exists, the pulse is oscillated in the original cycle of the oscillator 4. The output signal supplied from the oscillator 4 is integrated by the integral network 5 and the integrated signal is switched to the prescribed level through the waveform shaping circuit 14 to be supplied to the output circuit 15. Thus the reply speed can be increased for the reception signal.
