IPC: G01S7/48
Filed: 1985-10-17
Abstract: PURPOSE:To automatically avoid unnecessary proximity signals by restarting the operation of a counter or a shift register by a reset signal and delaying the subsequent light projecting timing by a given period. CONSTITUTION:Light is emitted from a light emitting element circuit 9 to an object and reflected waves are received by a phototransistor circuit 8 at the same timing, passing a synchronous amplifier 3. The output signals of the levels above a given threshold value among the photoelectric signals outputted from a preamplifier 2 appear on the output side of a comparator 13 and include unnecessary signals due to external light. Therefore, when the logical product of the output voltage of the comparator 13 and the voltage of the junction 12 of a counter 12 is obtained, the presence of the unnecessary signals at a waveform just before a light projecting timing can be detected. When the unnecessary signals are detected, the output of the circuit 14 is rendered a level H, the counter 12 is set, the timings of junctions T0, T1 and T2 become signals shifted from original signals by two references and light can be projected while avoiding the unnecessary signals.
