Apparatus equipped with motor

Abstract

An apparatus includes a driven member, a DC brushless motor, a first signal generation unit configured to output a first signal according to rotation of the DC brushless motor and to change an output value of the first signal each time the DC brushless motor rotates by a predetermined amount, a movement unit configured to move the driven member by a driving force of the DC brushless motor, a second signal generation unit configured to output a second signal each time the driven member moves by the predetermined amount, and a control unit configured to control driving of the DC brushless motor based on the output value of the first signal and a value of a number of times that the second signal is output during a period in which the DC brushless motor rotates by a predetermined amount.
