。[Claims for Utility Model Registration] A focus adjustment member for moving a photographic lens forward and backward is movably disposed on a substrate, is biased to move in one direction by a spring, and is moved by a motor. In a camera in which the focus adjustment member is held at the focus position by a locking member against the biasing force of the spring during focusing, the braking time of the motor is related to the amount of movement of the focus adjustment member. The camera is characterized in that the rotational speed of the motor is decelerated based on the braking time before the focus position, and the motor is stopped at the focus position, thereby holding the photographing lens at the focus position.
