物体検知装置。 The light reflected by the object to be detected of the projection beam emitted from the projection section towards the detection area is received by the light receiving section arranged in a triangular manner with respect to the projection section and the object to be detected. After converting the two received light outputs into currents and voltages, both voltage signals are input to an arithmetic circuit, and the output voltage of this arithmetic circuit is compared with a reference voltage in a comparator circuit to determine the presence of the object to be detected within the detection area. An object detection device that detects the presence or absence of an object includes: an integrating circuit that has a time constant longer than the rate of change in the output of the arithmetic circuit due to movement of the object to be detected within a detection area and integrates the output of the arithmetic circuit; An object detection device comprising: an addition circuit or a subtraction circuit that adds or subtracts the output voltage of the output voltage and a detection distance setting reference voltage and outputs the result as a reference voltage for comparison of the comparison circuit.
