<p>PROBLEM TO BE SOLVED: To provide an object recognition device capable of transmitting a presence direction of an object.SOLUTION: An object recognition device 1 includes a sensor unit 11, an installation part 13 having the sensor unit 11, and a control part 50. In the sensor unit 11, an ultrasonic element 21 transmitting an ultrasonic wave to one surface side of the sensor unit 11 and receiving a reflection wave of the ultrasonic wave and a vibration element 23 transmitting vibration to the other surface side of the sensor unit 11 are provided so as to have a corresponding physical relationship. The control part 50 drives the vibration element 23 in accordance with a signal outputted from the ultrasonic element 21 receiving the reflection wave after making the ultrasonic element 21 transmit the ultrasonic wave.</p> |
