A lens protecting cover-attached camera includes a moving mechanism. Thus, a simple mechanism is used to turn on or off a main power switch and for opening or closing a lens protecting cover responsively to manipulations performed on a single manipulating member. A supporting shaft for supporting the lens protecting cover is placed so as to be parallel to a plane substantially perpendicular to the optical axis of a photographic lens. When the supporting shaft is moved along the optical axis of the photographic lens, the moving mechanism causes the lens protecting cover to rotate around the supporting shaft at the center from a closed position to an open position. At the closed position, the lens protecting cover shields the face of the photographic lens. At the open position, the lens protecting cover exposes the face of the lens. Moreover, the moving mechanism turns on or off the power switch in response to a movement made along the optical axis of the photographic lens.

Lens protection cover-attached camera

A lens cover mounted camera with a lens cover movable to selectively assume at least a closing condition that covers a front surface of a photographing lens and an opening condition that exposes the front surface of the photographing lens, and further having a lens cover operating member for conducting the opening and closing operations of the lens cover and further for shifting the lens cover in directions of the optical axis of the photographing lens. When the camera is switched to a using condition or a non-using condition, the lens cover is respectively shifted to an opening position or a closing position through the lens cover operating member. This design minimizes the protruding quantity of the lens cover from a camera body and prevents the lens cover from being easily broken even if a careless external force or shock works on the lens cover during the use of the camera.

A flash emitting apparatus has a straight-tube type flash discharge tube and a reflector for accommodating the flash discharge tube which condenses and reflects an emission of the flash discharge tube to direct light forward, the apparatus including: a pair of electrodes disposed on opposing end portions of said flash discharge tube; discharge tube supports for supporting the flash discharge tube on said reflector; a frame member having said flash discharge tube and said reflector disposed therein; and restriction members formed internally of said frame member for restricting movement of said flash discharge tube in a longitudinal direction coaxial with a line connecting the pair of electrodes so as to retain the flash discharge tube within a certain range with respect to the reflector.
