A camera having a barrier according to the present invention includes a barrier unit in a space between a front main body and a front metal cover serving as an exterior member. Rotation of a barrier driving motor is transmitted to a rotary shaft member passing through the front main body, thereby allowing opening/closing actions of the lens barrier between a protection position for a photographing lens and a lens-barrier retracted position. The front main body is sealed waterproof by an O-ring provided to the outer circumferential surface of the rotary shaft member. With the lens barrel of the camera, rotation of a rotary moving frame is effectively transmitted to a cam frame through a cam follower fit to a linear-action groove, using a circumferential groove and the linear-action groove of a bayonet mechanism.

Camera having barrier

A digital camera having an acoustic member includes a first cover, a water-proof sheet and a second cover. The second cover is spaced from the water-proof sheet. The first cover has a first sound hole opposed to the acoustic member. The water-proof sheet is disposed such as to covers the first sound hole. The second cover has a second sound hole. The second sound hole is deviated in position toward an outer periphery of the first sound hole so that the second sound hole is not located on an extension of an axis of the first sound hole.
