Claims

[Scope of claim for utility model registration] (1) In an appropriate place in an area divided by a partition, etc.
In an ultrasonic detection device including an ultrasonic sensor including an ultrasonic oscillator and a receiver, the ultrasonic sensor detects whether or not an object exists within the area, comprising: An ultrasonic detection device characterized in that a sensitive area of the ultrasonic sensor is limited to a certain height or less by providing an upper shielding plate facing slightly downward on the front surface. (2) In front of the ultrasonic sensor, there is an upper shielding plate that faces downward from the upper end of the opposing partition, a lower shielding plate that slopes at an appropriate downward angle, and a lower shielding plate that faces left and right with an appropriate opening angle. Ultrasonic detection according to claim 1, characterized in that the sensitive area of the ultrasonic sensor is limited vertically and horizontally by providing a blocking frame consisting of a pair of opposing side blocking plates. Device. (3) A claim characterized in that the upward inclination angle of the upper shielding plate can be adjusted by pivoting at least the upper shielding plate about a horizontal axis on the front surface of the ultrasonic sensor. The ultrasonic detection device described in (1) or (2).
