Abstract: A lens barrel of the invention is configured with a first barrel member, a second barrel member which rotates around an outer periphery of the first barrel member and which has a through hole between an outer peripheral surface and an inner peripheral surface, and a moisture permeable member provided so as to cover the through hole of the second barrel member.

Abstract: A lens barrel includes a moving frame, a stepper motor that drives the moving frame, a screw member that rotates in accordance with rotation of the stepper motor, a screw gear that rotates in accordance with rotation of the screw member, a nut member that screws with the screw member, moves, by pressing, the moving frame, an external rotation operation ring, including a drive gear that rotates in response to external operation, that switches between a first state where the drive gear meshes with the screw gear, rotates the screw member, and drives the moving frame and a second state where the drive gear and the screw gear are not meshed, and control means that drive-controls the stepper motor in conjunction with rotation of the external rotation operation ring when the external rotation operation ring is in the second state.

Abstract: 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.
