Abstract: A film feeding device for a camera uses first and second electric motors associated with first and second planetary gearing mechanisms, respectively. In one embodiment, the first motor and first planetary gearing mechanism drive a spool shaft of a film cartridge to supply film to a winding spool. The winding spool is driven by the second motor and second planetary gearing mechanism to wind film onto the winding spool, at which time the first motor is stopped and the first planetary gearing mechanism is automatically disconnected from the spool shaft. For rewinding, the second motor is operated in reverse and the second planetary gearing mechanism is automatically disconnected from the winding spool and connected to the spool shaft of the film cartridge.

Abstract: A camera includes a cartridge chamber in which a film cartridge is loaded, a spool chamber in which a take-up spool is mounted, and an aperture disposed between the cartridge the chamber and the spool chamber. The camera has a mechanism which feeds film out of the cartridge by rotating a spool shaft of the cartridge loaded in the cartridge chamber, and leads the film past the aperture to the take-up spool. The camera is further provided with a cartridge cover for concealing the cartridge chamber when it is closed and for exposing the cartridge chamber when it is open. A rear cover which is openably mounted on the rear side of the camera body, conceals the aperture and the spool chamber when it is closed and exposes the aperture and the spool chamber when it is open.

Abstract: A film feeding apparatus in a camera comprises a feeding device for feeding film from a film cartridge, a take-up spool device for taking up the film fed by the feeding device, and a judgment device for judging on the basis of a variation in the movement speed of the film whether the film has been taken up by the take-up spool. The movement speed of the film is determined by the feeding device before the film extending from the film cartridge is taken up by the take-up spool device, and the movement speed of the film is determined by the take-up spool device after the film has been taken up by the take-up spool device. The movement speed of the film driven by the feeding device differs from the movement speed of the film driven by the take-up spool device.

Abstract: A camera has a magnetic head for data recording and reproduction disposed in opposed relationship with a data recording portion provided on film loaded into the camera and adapted to be biased against the film, a pad for pushing the film into contact with the fore end surface of the magnetic head, and a positioning portion formed on the magnetic head. Further, a reference surface is formed in opposed relationship with the positioning portion and bears against the positioning portion to thereby position that surface of the magentic head which contacts with the film at a position in which no deformation is caused in the film. As the reference surface, use may be made of an outer film guild rail which is originally provided in the camera.

Abstract: This invention relates to cameras operable to select one film supply system from either a normal wind-up system or a preparatory wind-up system. The camera has a selector switch for selecting one of the film supply systems, and an inhibiting means for inhibiting that the two systems are applied to one film by the switch, a write means for recording selected information onto a film or a storage device provided in the cartridge, and a read means for reading the selected information and the frame information written in the device. The switch selects a film supply system which is indicated by the selected information read out from the device of the loaded film by the read means. Additionally, a film supply means is provided for preparing and supplying the film in accordance with the frame information read out by the read means. The film supply means can wind up the film to supply even when either of the two film supply systems is set.
