摘要： A lens-fitted photographic film unit has a main body, which incorporates a photo-taking mechanism, and is pre-loaded with unexposed photographic film at its rear. A rear cover covers the rear of the main body in light-tight fashion. The rear cover has a pair of hooks. A receiving hole is formed in the main body, in which the hooks are engaged so as to retain the rear cover on the main body unremovably. To separate the rear cover from the main body, a reversal-preventing claw having the receiving hole therein is broken away from the main body, whereby the claw having the receiving hole is retained on the hooks. This prevents used parts from becoming inadvertently mixed up with new parts when certain other parts of used film units are retrieved for reuse.

摘要： A camera view finder having at least two types of finder field frames such as a full-size field frame and a panoramic field frame, only one of which can be observed in accordance with a selected photography mode. In a first embodiment of an Albada-type inverted Galilean view finder, one of two types of finder field frames is light-shielded by a blocking member. In a second embodiment, a finder field frame is formed on each of at least two adjacent surfaces of a transparent cubic body which is rotated to position a selected finder field frame in the finder optical path. For a Keplerian view finder, a finder field frame is formed on each side of a transparent plate which is moved along the finder optical path to position a selected one finder field frame in the real image plane.

摘要： A camera has first and second switches which turn ON/OFF in association with a wide-angle/telephotography changeover member. The first switch turns ON when the wide-angle/telephotography changeover member is in the wide-angle position, and the second switch turns ON when the wide-angle/telephotography changeover member is in the telephoto position. An incorrect lens setting signal is generated when both the first and the second switches are OFF. Upon generation of the incorrect lens setting signal, an incorrect position display is actuated and the operation of the camera is stopped.

摘要： A camera of the type in which a film magazine is inserted axially into a film loading chamber, has a film loading door rectilinearly movable for closing and opening the film loading chamber, and a back door pivotally mounted on the back of the camera for closing and opening a guideway between a film pressure plate and the camera body. Rectilinear movement of the film loading door to its open position causes a latching member to disengage itself with the back door. On the other hand, the film loading door is restricted in its open position by engagement with the latching member and, in turn, allowed to return under the influence of a spring force to its closed position by pivotal movement of the back door which releases this engagement.

摘要： A lens-fitted photo film unit is pre-loaded with photo film, and includes a viewfinder adapted for observing an object. A selector button is operable externally, for being shifted to a standard position and a telephoto position. A view region changer lever sets the viewfinder in a standard view field when the selector button is in the standard position, and sets the viewfinder in a telephoto view field when the selector button is in the telephoto position, the telephoto view field being included in the standard view field. An information exposure unit photographically records a telephoto discernment PAR code to an information exposure region in the photo film when the selector button is in the telephoto position. The telephoto discernment PAR code includes at least three dots, for designating production of a pseudo telephoto print from a region in an imaging frame in the photo film corresponding to the telephoto view field.

摘要： An optical adapter comprises an adapter body and a lens member. The lens member is a cylindrical lens having one or more curved surfaces, and has a function to extend an optical image in a horizontal direction. A taking lens and a viewfinder are arranged vertically, and the optical axes of the taking lens and the viewfinder coincide with each other in the horizontal direction. When the adapter body is attached to the front side of the lens-fitted photo film unit, the front surfaces of the taking lens and the viewfinder are covered with the lens member. The center of the lens member in the horizontal direction coincides with centers of the taking lens and the viewfinder in the horizontal direction.

摘要： A flash device for a lens-fitted photo film unit pre-loaded with unexposed photo film is provided. A main capacitor stores charge. A flash emitter emits flash light. A flash circuit board charges the main capacitor, and drives the flash emitter by discharging the main capacitor in response to an exposing operation. A tightly closed flash case is secured to the lens-fitted photo film unit, for containing the main capacitor, the flash emitter and the flash circuit board. Also, the lens-fitted photo film unit includes a sync switch for generating a trigger signal in response to the exposing operation. Two switch contact points are disposed outside the flash case, for receiving the trigger signal from the sync switch. The two switch contact points disable discharge of the main capacitor while the flash case is away from the lens-fitted photo film unit, and are short-circuited for discharge of the main capacitor upon supply of the trigger signal while the flash case is secured to the lens-fitted photo film unit.

摘要： A shutter device has a shutter drive lever striking a shutter blade to expose an exposure opening, a mooring lever, a cam, and a speed governor. The speed governor includes an escapement wheel with integrally formed two gear wheels, an anchor, and a movable mounting board on which the escapement wheel and anchor are mounted. One of the gear wheels of the escapement wheel is engaged with a claw of the anchor to slow down a rotational speed of the escapement wheel. The other gear wheel is engaged with a shutter speed adjustment gear formed in a periphery of the shutter drive lever. The shutter drive lever rotates at the same rotational speed as the escapement wheel, so that exposure time becomes long. When flash charge is turned off, the mounting board moves to an evacuation position in which the escapement wheel is disengaged with the shutter speed adjustment gear.

摘要： A front cover, a rear cover and a base portion are crushed into a crushed material, and further pelletized into a recycled plastic pellet. The recycled plastic pellet is used as a part of a molding material to produce mold plastic parts for a photosensitive material. When the molding material is melt in heat, a thermoplastic resin is deteriorated by heat or modified. Therefore, properties and qualities of recycled plastic mold parts are less than those of new ones. Further, when the thermoplastic resin is deteriorated by heat, the photosensitive material reacts with the thermoplastic resin to decomposed products having an bad influence on photographic characteristics. In order to prevent the deterioration by heat, oxidation inhibiting materials are added, and in order to absorb the decomposed products, carbon blacks are added.
