1. An object detection device that comprises: a transmitter having a transmitting detection unit for transmitting detection beams for object detection; and a receiver, having a receiving detection unit for receiving the detection beams, for outputting a detection signal, and that detects an object based on a signal level of the detection signal, the object detection device comprising:
an angle adjustment mechanism for adjusting angles of each detection unit based on the signal level of the detection signal; and a level output section for outputting the signal level of the detection signal to an external unit, wherein the angle adjustment mechanism includes: a horizontal angle adjustment section having: a horizontal rotation component for rotating the detection unit in a horizontal direction; and a horizontal adjustment-engagement member which drives the horizontal rotation component to adjust a horizontal angle of the detection unit rotatable about a vertical axis, and which is engageable with the external unit; and a vertical angle adjustment section having: a vertical rotation component for vertically rotating the detection unit; and a vertical adjustment-engagement member which drives the vertical rotation component to adjust a vertical angle of the detection unit rotatable about a horizontal axis, and which is engageable with the external unit, and the horizontal adjustment-engagement member and the vertical adjustment-engagement member are positioned adjacent to each other such that portions thereof are exposed on a front surface of the object detection device, are removably engaged with an external automatic angle adjustment unit from front surfaces, and are driven by the automatic angle adjustment unit, and an angle of each of the horizontal adjustment-engagement member and the vertical adjustment-engagement member is automatically adjusted based on the signal level of the detection signal outputted by the level output section. |
