検出装置。A thin beam of light emitted from the light emitting section is guided to the light receiving section while being repeatedly reflected by two right angle prisms facing each other with the detection region in between, and the received light output is processed to detect the presence or absence of an object that has entered the detection region. The object detection device uses identification light, and the two right-angle prisms are composed of a first right-angle prism and a second right-angle prism having a cut-off top facing the slope, and both right-angle prisms are They face each other so that their slopes are parallel and their center lines are slightly shifted, and the output beam of the light receiving part is incident on the end of the slope of either one of the right angle prisms at a substantially right angle, and the light receiving part is connected to the second prism. 1. An object detection device using light, characterized in that the device is disposed at a position to receive light emitted from the cut-off top of a right-angled prism.
