Abstract

PURPOSE:To measure a distance without being affected by background bodies by arranging a transmitter and a receiver so that their sound axes cross each other nearby a short-distance sounds field critical point. CONSTITUTION:The ultrasonic wave transmitter 2 and ultrasonic wave receiver 3 are packaged in a resin case 6 at such a specific angle that their sound axes cross each other nearby the short-distance sound field critical point in front of an ultrasonic sensor 1. Then a slit 7 is formed between the transmitter 2 and receiver 3 to reduce the leak of a direct wave from the transmitter 2 to the receiver 3, thereby enabling a short distance to be measured. Further, the sound axes of the transmitter 2 and receiver 3 cross each other within a range where ultrasonic wave beams generated by them do not spread, so a composite beam with narrow width is generated within a detection range and an extremely small body is securely detected. Further, a composite ultrasonic wave by the transmitter 2 and receiver 3 is limited spatially, so there is not any influence of background bodies.
