ABSTRACT:
An electronic apparatus which is equipped with an ultrasonic motor and which consumes only a small amount of electric power, is stable in performance, and is capable of accurately controlling the angular position is offered.
A driving pulse storage circuit stores driving pulses corresponding to the environment of the components of the ultrasonic motor. A stopping pulse storage circuit stores stopping pulses corresponding to the environment of the components of the motor. An environment detection means detects the environment of the components. An output pulse-selecting circuit receives the output signal from a driving pulse-generating circuit and the output signal from a stopping pulse-generating circuit and produces output pulses corresponding to the output signal from a detection signal-generating circuit to a piezoelectric vibrator-driving circuit. The moving member and the output means are operated by ultrasonic vibration of the vibrating member.
