Abstract

PURPOSE:To realize a measurment of distance up to an object that is put at the dead angle area of a ultrasonic wave, by detecting the rotating angle started from the reference position of the wave transmitter and receiver and then carrying out an operation for a value of sine wave the detected angle and a delay time duration during the transmission/reception of wave. CONSTITUTION:The ultrasonic wave radiated from the wave transmitter 1 and reflected by an object 3 is received 4, and the signals corresponding to the time duration between the transmission of ultrasonic wave and the reception of reflected wave are measured 17 to measure the distance between the transmitter 1 and object 3. In this case, an interlocking is secured between the wave transmitter 1 and receiver 4, and these transmitter and receiver are turned by the pinion 15 and within a range of prescribed angle omega. During this rotation, the rotating angle thetai started from the reference position of the transmitter 1 or receiver 4 is detected 16. Then a multiplication 18 is carried out between the sine wave value of the detected angle thetai and the measured value of the signal corresponding to the time duration during the transmission/reception of wave. This multiplied value is applied to the display device 19 to display the distance between the transmitter 1 and the object 3 when the object 3 is shifted in parallel up to the position where the transmitter 1 is attached.
