摘要： An apparatus for controlling an electrically driven film transport mechanism includes a displacement member that controls a change-over switch for selecting either a film take-up mode or a film rewind mode, and first and second members for controlling the position of the displacement member. The first member, which is responsive to film tension, automatically causes the displacement member to select the film take-up mode at the end of film rewind, thereby halting the film transport mechanism. The second member has a first position at which it holds the displacement member in a film take-up selecting mode for film take-up, and has a second position which enables movement of the displacement member to a film rewind selecting mode. Upon initial film advancement to load a fresh roll of film into the camera, the second member is automatically returned to its first position.

摘要： 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. In a second embodiment, the first motor and the first planetary gearing mechanism are employed to drive the spool shaft of the film cartridge in a film supply direction or a film rewind direction, and the second motor and the second planetary gearing mechanism are only used to drive the winding spool in a film winding direction.

摘要： A film rewind device in a camera in which a rewind coupling is automatically engaged with a cassette shaft in response to rewind operation has a rotatable member having a spiral groove on its peripheral wall portion and said rewind coupling at the end of the shaft thereof, the rotatable member being slidable in axial direction and rotatable by rewind operation, and a meshing member meshing with the spiral groove at the initial stage of the rewind operation to thereby slide the rotatable member in axial direction to cause the coupling to engage the cassette shaft. The mesh engagement between the meshing member and the spiral groove is released in axial direction when the coupling engages the cassette shaft, so that the meshing member comes to support the rotatable member so as to block the return of the rotatable member in axial direction.

摘要： 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.

摘要： 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.
