るようにしてなる障害物検知装置。On one side of the detection section, transmitters are arranged with receivers for ultrasonic signals sandwiched between them, and the transmitters are driven under the control of a transmission timing circuit to generate ultrasonic waves emitted from the transmitters. In an obstacle detection device that detects an obstacle by measuring the distance to the obstacle from the time it takes for a signal to be reflected by the obstacle and received by the receiver, the transmission timing circuit Drives the transmitters on both sides of the receiver at the same time,
An obstacle detection device configured to process an ultrasonic signal received by the receiver using a measuring means.
