摘要： A camera lens shutter having separate aperture blades and shutter blades arranged in a manner to provide a shutter unit having decreased thickness. The lens shutter includes a first shading member to expose an exposure aperture when in an open state and to cover the exposure aperture when in a closed state. A first circular cam drives the primary shading member. A second shading member forms a plurality of aperture diameters, and a second circular cam drives the second shading member. The inner diameter of either the first or second cam is made larger than the outer diameter of the other. The lens shutter may also include a shading member to expose an exposure aperture wherein an open state, a first circular cam to drive the first shading member, a second shading member to cover or close the exposure aperture, a second circular cam to drive the second shading member, a third shading member to form a plurality of aperture diameters, and a third circular cam to drive the third shading member. The respective cams of the shutter units are positioned concentrically and may be on approximately the same plane to provide a thinner shutter unit.

摘要： A camera capable of closing a barrier in accordance with need, even an interchangeable lens is mounted. The camera is provided with a connection portion, a barrier member and a barrier control section. The connection portion is detachably connected with the interchangeable lens and is provided with an aperture portion, which allows object light to pass therethrough. The barrier member is movably provided, in the state the interchangeable lens is connected with the connection portion, between a closed position, the barrier member closes off the aperture portion of the connection portion, and an open position, the barrier member is withdrawn from the light path. The barrier control section judges a state of mounting of the interchangeable lens to the connection portion, controls the barrier member to the closed position if the interchangeable lens is not mounted, and to the open position if mounted and a predetermined first condition is satisfied.

摘要： A caulking pin joint for use with a light shielding blade in a shutter or aperture mechanism of a camera. The caulking pin has a disc-shaped head, a circular protrusion depending therefrom, and a hollow-circular segment depending from the circular protrusion. The actuation arm of the shutter or aperture rests on the head, while the light shielding blade rests on the circular protrusion. The hollow circular section is then spread outward so as to rotatably secure the actuator arm to the light shielding blade. The interior surface of the hollow circular section is chamfered such that when it is folded over on top of the light shielding blade, it presents only a small smooth protuberance from the light shielding blade. This allows a second light shielding blade to be positioned close to the first light shielding blade without fear of collisions or interference between the blades. The circular protrusion upon which the light shielding blade rests, may be provided with a surface inclined up to and including 15.degree. for receiving the light shielding blade. A punch and dye is used to deform both the hollow section and the periphery of the insertion hole in the light shielding blade.

摘要： A camera accessory is equipped with an accessory mount assuming a bayonet structure with first through third tabs set over intervals along a circumference and projecting from inside of the accessory toward the outside. The mount is structured so that insertion of the mount is allowed when the mount is inserted at a correct interlock phase without any of the first through third tabs contacting any of three camera body-side tabs, and that insertion of the mount is disallowed if the accessory mount is positioned at an incorrect interlock phase with at least two tabs contacting at least two of the camera body-side tabs. The first through the third tabs extend along varying lengths along the circumference. When the first tab and either other tab contacts two of the camera body-side tabs at a total of two contact locations, the first tab contacts near the second side end.
