Abstract

PURPOSE: To reduce the restriction of an arranging condition by forming a burst signal by an oscillation circuit and driving an ultrasonic sensor by the burst signal from the oscillation circuit to transmit an ultrasonic wave and receiving the ultrasonic wave reflected by an object.
CONSTITUTION: Ultrasonic sensors 251, 252, 253...receive a burst signal from an amplifier 22 through a switch 23 and a switch bank 24 when the switch is turned ON to be driven to transmit a burst signal (ultrasonic wave). Vibration is generated by the application of the burst signal and suppressed by a resonance suppressing circuit after the ultrasonic wave is transmitted. The ultrasonic sensors 251, 252, 253...are used as both of transmitter ultrasonic sensors and receiving ultrasonic sensors and the restriction of an arranging position due to directionality is reduced.
