Camera having a lens barrier

Abstract

A camera is provided with a lens barrier for covering and uncovering an opening which is formed in a front face of the camera and is for exposing a taking lens. The lens barrier protects the taking lens when the camera is not used. The lens barrier is driven by a motor. This motor is controlled by a motor control unit relative to its rotational direction (forward and backward direction), its rotational amount and its rotational speed. As the motor, a DC motor is used. Into this DC motor, drive-pulse trains having different duty factor are inputted to control the rotational speed. Owing to this, an operation speed of the lens barrier is controlled so as to be faster when the lens barrier opens the opening, and so as to be slower when the lens barrier closes the opening.
