Abstract
PURPOSE: To dispense with a heavy frame, beam or the like and simplify the entire construction, by displacing a movable unit by a signal supplied through a guide rail.
CONSTITUTION: The output signal of a pulse generator OS is applied to a sound generator 36 through a capacitor Co, a rail 21 and a wheel 31. A sharp sound generated by discharge or the like is detected by means 41, 42, the output of which are supplied to a calculation circuit CK. The time of propagation of the sound wave from the sound generator 36 to the means 41, 42 is calculated to determine the position of a movable unit 3 on a guide rail 2. A signal of the position is applied to a driving circuit OP, which supplies an output signal lo to a driving motor 37 housed in the movable unit 3 so that the position signal is equalized to a measured signal lm. The motor 37 displaces the movable unit 3 on the rail 2 depending on the magnitude of the measured signal lm. The signal lm is detected from the position of a pointer 35.
