Abstract: A stopper piece of a regulating member is abutted against a receiving portion formed at a lever of a display mechanism. The stopper is biased in a regulating direction by the force of a torsion coil spring. A projecting piece is abutted against a lever of a releasing member so that the stopper piece can be kept at a position where the rotation of the lever is regulated. The lever of the releasing member is supported in such a manner to move back and forth freely, and is held at the position where the rotation of the lever is regulated before a film pack is set. A trigger plate is formed at the lever. When a pack main body is set at a final position, the trigger plate is pushed by a pack main body and move. When the trigger plate is moved, the lever pushes a lock lever so that the regulation of the lever's rotation by the stopper can be released.

Abstract: A camera, which uses a film cartridge having a film exposure status display, comprises an E2PROM. The E2PROM stores the fact that the film status determination operation is underway when film status determination operation is underway. When a power supply is removed while the film status determination is operating and then the power supply is mounted, the camera operates an initial process. The film exposure status display is set in `exposed` because the E2PROM holds that the film status determination operation is underway. A camera is .provided that deems the film in the film cartridge to have been exposed and does not perform exposure if the power supply is cut off while the determination of the film status of the film in the film cartridge mounted in the camera is underway.

Abstract: An information processing device, such as a camera, capable of magnetically recording information on film, controls magnetic recording and film feeding using a single position detector that detects film position information, such as perforations in the film. After a frame of the film has been photographically exposed, the information processing device first feeds the film in a reverse direction opposite to the direction of advancement, before accelerating the film forward in the advancement direction to a stable advancement velocity. The usable length of the magnetic recording area of the film is thus increased because recording does not take place while film velocity is changing.

That a photographer's finger was resting on a strobe window of the camera during exposure of a frame under strobe light is detected, and when it is detected, the recording system records an instruction on printing of the exposed frame taking into account the fact that the frame was exposed under strobe light with a photographer's finger resting on the strobe window.

Abstract: The lens body of a camera for sensing moving images is adapted for producing a stereoscopic image by first and second spaced apart optical deflectors. The deflectors include reflective surfaces which lie in parallel planes with respect to one another and which are disposed at an angle to the optical path of incoming image rays. The second deflector lies generally in the optical path of the incoming image rays and deflects incoming image rays from the scene to the first deflector which lies in the path of the deflected rays. The first deflector in turn deflects the image rays to the image sensing means in the camera body. Both deflectors are caused to rotate slowly about an axis defined by the optical path of the incoming image rays while maintaining their relative positions with respect to one another. The orientation of the lens with respect to the image sensing means of the camera remains fixed during rotation of the deflectors.
