Claims

[Claims for Utility Model Registration] (1) An ultrasonic transducer that emits ultrasonic waves onto a measurement surface and receives reflected waves from the measurement surface, and an ultrasonic transducer that drives this ultrasonic transducer or receives the reflected waves. An ultrasonic range finder comprising: a transducer that calculates the distance to the measurement surface; An ultrasonic distance meter comprising: a sponge-like sheet provided on the measurement surface side so as to surround the measurement surface. (2) An ultrasonic transducer that emits ultrasonic waves to a measurement surface and receives reflected waves from the measurement surface, and an ultrasonic transducer that drives this ultrasonic transducer or receives the reflected waves and calculates the distance to the measurement surface. An ultrasonic range finder comprising a transducer for calculation processing, an umbrella-shaped reflective umbrella that expands toward the measurement surface so as to surround the ultrasonic transducer, and a vibration sensor attached around the ultrasonic transducer. An ultrasonic distance meter characterized by comprising a unit. (3) An ultrasonic transducer that emits ultrasonic waves to a measurement surface and receives reflected waves from the measurement surface, and an ultrasonic transducer that drives this ultrasonic transducer or receives the reflected waves and calculates the distance to the measurement surface. In an ultrasonic distance meter, the ultrasonic distance meter includes an umbrella-shaped reflector that expands toward the measurement surface so as to surround the ultrasonic transducer; An ultrasonic distance meter comprising a previously attached nozzle and a gas delivery unit that sends pressurized gas to the nozzle. (4) The ultrasonic distance meter according to claim (1), further comprising a vibration unit attached around the ultrasonic transducer. (5) The reflector is provided with an introduction hole for introducing air pressure into the interior thereof, and pressurized air is sent into the introduction hole from the purge set so that the pressure is slightly higher than the pressure in the surrounding space. Claim (1)
) Ultrasonic distance meter. (6) The ultrasonic distance meter according to claim (5), further comprising a nozzle provided on the reflector and blowing toward the sheet by air pressure from an air blowing means. (7) The ultrasonic distance meter according to claim (6), further comprising a vibration unit attached around the ultrasonic transducer.
