ツチを利用した物体検出装置。[Claims for Utility Model Registration] (1) An ultrasonic switch that is on the same axis perpendicular to the direction of movement of the object to be detected and that transmits ultrasonic pulses to one side of the space in which the object to be detected moves. ,
An ultrasonic switch that operates by receiving the transmitted ultrasonic pulse is installed on the other side facing this, and the ultrasonic switch is operated when the object to be detected crosses the ultrasonic pulse. In the apparatus for detecting an object to be detected, the ultrasonic switch on the transmitting side of the ultrasonic pulse is a reflective ultrasonic switch, and the ultrasonic switch on the receiving side is a transmissive ultrasonic switch exclusively for receiving ultrasonic waves. An object detection device that uses an ultrasonic switch as a sensor. (2) An ultrasonic switch that is on the same axis perpendicular to the direction of movement of the object to be detected and that transmits ultrasonic pulses to one side of the space in which the object to be detected moves;
An ultrasonic switch that operates by receiving the transmitted ultrasonic pulse is installed on the other side facing this, and the ultrasonic switch is operated when the object to be detected crosses the ultrasonic pulse. The object to be detected is characterized in that the ultrasonic switch on the transmitting side of the ultrasonic pulse is a reflection type ultrasonic switch, and the ultrasonic switch on the receiving side is a reflection type ultrasonic switch. An object detection device that uses an ultrasonic switch.
