Abstract

PURPOSE:To open a barrier member only when necessary and to protect a photographic lens sufficiently by opening and closing the barrier member which has its center of rotation in the diameter direction of the photographic lens by an opening/closing member which is driven by the rotary transmission system of a focus control motor. CONSTITUTION:The focus control motor 11 is reversed at the end of shutter operation and a barrier opening/closing ring 18 returns counterclockwise until an opening/closing projection 18a collides against a position reference stopper 40. Further, when a main switch is turned off in this stand-by state, a focus control motor 11 rotates the barrier opening/closing ring 18 clockwise. The barrier opening/closing ring 18 returns until the opening/closing projection 18a strikes on an initial position stopper 39 and the barrier member 14 is closed with the force of a return spring 21. Consequently, the barrier member 14 is closed every time a photograph is taken, so the photographic lens, etc., in a photographic lens barrel B is protected sufficiently.
