ABSTRACT:
A lens barrier apparatus includes a lens barrier having opened and closed positions, The lens barrier is positioned on the front face of a lens barrel and protects a camera lens. A motor which drives the opening/closing of the lens barrier and an encoder outputs a predetermined signal together with the rotation of the motor. A drive control when a battery is loaded in the camera, drives the motor in a direction in which the lens barrier is closed and, when the predetermined signal is not output from the encoder during the driving process, drives the motor in a direction in which the lens barrier is opened and then drives the motor in the direction in which the lens barrier is closed again.
