摘要 PURPOSE:To provide the camera with a barrier which allows the reduction of the size in the optical axis direction of the photographic lens of the camera with the barrier and allows the focusing control with high accuracy even if the turning control of a driving source for focusing is executed with relatively low accuracy. CONSTITUTION:This camera has the photographic lens 1, a driving member 10 having a rotating axial line parallel with the optical axis of the photographic lens 1, a driving source for turning the driving member, a sectorial lever coaxially mounted to the driving member, a barrier opening/closing lever for opening and closing the barrier by engaging with the sectorial lever, and at least one piece of focusing rings 4 engaging with the sectorial lever 14. The focusing rings engage with the end of the arc part of the sectorial lever and have the slopes which can turn the focusing rings and on which the arc part of the sectorial lever slides.
