A detection processing unit determines, in a detection area including optical axes formed between emitter elements and receiver elements, whether each optical axis is in an interrupted state after optical axis selection corresponding to one scan, and outputs a detection signal based on the determination result. When at least one of the optical axes is constantly interrupted by an object movable within the detection area, the detection processing unit outputs the detection signal upon determining that the number of optical axes in an interrupted state is greater than a preset maximum optical axis number, and also outputs the detection signal upon determining that the number of optical axes in an interrupted state is smaller than a preset minimum optical axis number.
