ABSTRACT:
A camera for use with a thrust type cartridge having a spool and a photographic filmstrip and method for transporting film in a camera. The camera has a body that defines cartridge and supply chambers and an exposure frame between the chambers. A spindle is disposed in the cartridge chamber to engage the cartridge spool. A supply spool is disposed in the supply chamber and is rotatable about an axis. A cincher is disposed in the supply chamber to cinch the filmstrip to the spool. A film drive is in engagement with the supply spool and the spindle to rotate the supply spool and spindle in opposed advance and rewind directions. A film winder is mounted to the body and is pivotable in first and second opposite directions relative to the body through an arc of less than a full circle. A ratchet and pawl mechanism connects the film winder to the film drive. The ratchet and pawl mechanism is mechanically engaged with the film drive in the first direction of pivoting of the film winder relative to the film drive. The ratchet and pawl mechanism is mechanically disengaged from the film drive in a second direction of pivoting. A crank is mounted to the body and is rotatable, relative to the body, through a full circle in forward and reverse directions of rotation. The crank is engageable with the film drive in both directions of rotation.
