摘要: A motor drive and control apparatus for camera compares the speed of movement of a driven member, as detected by an encoder pulse, against a deceleration curve stored in a storage of CPU so as to turn the motor on and off or brake the motor in conformity to the deceleration curve. When the motor is on adjacent to a target position, the on condition of the motor is limited in synchronism with the encoder pulse.
