Abstract: An imaging apparatus includes: an imaging unit configured to receive light collected from an object area through an imaging optical system provided at a front side facing an object, and to generate image data; a body unit including the imaging unit; an optical sight unit including a light source unit for emitting luminous flux, and a reflecting optical element for allowing light from the object area to transmit and reflecting the luminous flux toward a back side opposite to the front in order to produce a virtual image of the luminous flux in the object area or near the object area; and a leg unit that holds at least the reflecting optical element in a movable manner in a direction away from the body unit and in a direction perpendicular to an optical axis of the imaging optical system, at startup of the optical sight unit.

Abstract: The present invention provides a switch mechanism usable underwater including a rear cover serving as an exterior member, two shaft members being displaceable in a shaft direction and fitting into two shaft holes having the same cross-sectional area provided in the rear cover, an O-ring watertightly maintaining the shaft member and the shaft hole, and a lever member being engaged with the two shaft members in a manner to be capable of pressing-down or pulling-up the shaft member, and being configured to balance water pressure applied to one shaft member with that applied to the other shaft member.

Abstract: A switch mechanism usable underwater including a cover serving as an exterior member, a shaft member displaceable in a longitudinal direction and fitted into a shaft hole having substantially the same cross-sectional area provided in the cover, an O-ring maintaining a water-tight sliding seal between the shaft member and the shaft hole, and a lever member movable about an axis for moving the shaft member by application of a pressing force applied to the lever member in a first direction against a force of a bias member, the pressing force being applied at a first point which is a first distance from said axis, the lever member engaging the shaft at a second point a second distance from said axis which is less than said first distance to move the lever member in a second direction opposite said first direction when the pressing force is removed.

Abstract: A camera film feed device is provided for enabling freely loadable placement of a film magazine which has a takeup shaft on which a film is wound and which has a film leader protruding from a film feeding opening. The camera film feed device includes a magazine chamber into which the film magazine is loaded, a fork which joins in mating fashion with the takeup shaft of the film magazine loaded into the magazine chamber, a takeup spool which is positioned on a side of a photographing aperture opposite the magazine chamber and which takes up the film, a sprocket which is positioned between the magazine chamber and the takeup spool, and a control circuit which controls the operations of the fork, takeup spool and sprocket.

Abstract: A camera in which a magazine can be loaded into a magazine chamber in the direction along a winding shaft thereof in a state in which a film leader is wound thereon. During such magazine loading, the film leader is inserted along the outer periphery of a film guide disposed in the magazine chamber. After the magazine has been loaded, the film leader is temporarily rewound into the magazine. Then, it is fed toward a spool chamber. The film leader that has reached the spool chamber is advanced by the spool and film loading is completed. By employing such a loading mechanism, it is possible to provide a camera incorporating a film loading mechanism with a simple structure which is capable of reliable film loading and making it possible, in cameras using 135-type film magazine, to load a magazine in the axial direction thereof.

Abstract: This camera feed device is a camera film feed device enabling the freely loadable placement of a film magazine having a takeup shaft on which is wound film and in which the film leader protrudes from a film feeding opening; comprising a magazine chamber into which the film magazine is loaded, a fork which joins in mating fashion with the takeup shaft of the film magazine loaded into this magazine chamber, a takeup spool, on the other side of the photographing aperture opposite the magazine chamber, which takes up the film, and a control circuit which controls the operations of the fork, takeup spool and sprocket; and in which this control circuit starts an operation by the fork to rewind the film into the film magazine when the film magazine is loaded into the magazine chamber, stops the rewind operation when the film is rewound to a prescribed position, and then starts an operation by the sprocket to feed the film toward the takeup spool.
