Abstract
Disclosed is a means for rewinding on its associated spool, when necessary, a film, which has been unwound from the spool for feeding to a subsequent process, and storing the film, together with the spool, in a storing means. The film is rewound by a rewinding means while the portion of the film on the outer periphery of the spool is being held by the rewinding means, thereby preventing the film from undesirably unwinding. A gripping means transfers this rewound film to a clamping member of the storing means, whereby the rewound film is stored in the storing means.
Claims25
A photographic film handling apparatus which rewinds a photographic film on the associated spool and stores the rewound film in film storing means, comprising:
- (a) spool holding means which holds a flanged spool having one end of a film secured thereto at its shaft portions outward of the flanges;
- (b) rewinding means which rewinds said film on said spool while pressing against the outer periphery of the portion of said film already wound on said spool in a state wherein said spool is held by said spool holding means;
- (c) gripping means which grips said rewound film being held by said spool holding means and takes the former away from the latter;
- (d) film storing means including a clamping member which clamps said rewound film being gripped by said gripping means and takes the former away from the latter;
- and
- (e) shifting means which shifts said gripping means between a receiving position where said gripping means takes said rewound film away from said spool holding means and a transfer position where said gripping means transfers said rewound film to said clamping member of said film storing means.
A photographic film handling apparatus which rewinds any defective film on the associated cartridge which is detected when photographic films are unwound from the associated cartridges for being subjected to development, fixing and so forth, comprising:
- (a) spool holding means which holds a flanged spool having one end of a film secured thereto at portions of said spool near both its axial ends by a pair of spool chucks;
- (b) rewinding means which rewinds said film while pressing against the portion of said film on the outer periphery of said spool from opposite sides across the axis of said spool in a state wherein said spool is held by said spool holding means;
- (c) gripping means which clamps said rewound film being held by said spool holding means and takes the former away from the latter while radially pressing against the outer periphery of said film;
- (d) film storing means having a clamping member which clamps said film being gripped by said gripping means and takes the former away from the latter by means of a film pressing force which is stronger than that of said gripping means;
- and
- (e) shifting means which shifts said gripping means between a position where said gripping means receives said film from said spool holding means and a position wherein said gripping means transfers said film to said film storing means.
A photographic film handling apparatus which allows a film once unwound from its associated spool to be rewound thereon and taken out when necessary, comprising:
- (a) spool holding means including a pair of spool chucks which are provided in such a manner as to correspond to each of the ends of the shaft of a spool by which one end of a film is retained, these spool chucks moving toward and away from each other, thereby allowing said spool to be held or released from the hold of said spool chucks;
- (b) rewinding means including a pair of nip rollers which clamp the portion of said film on the outer periphery of said spool, said nip rollers being adapted to rotate such as to rotate said film, together with said spool, thereby rewinding said film on said spool;
- (c) gripping means including a resilient member which has the shape of a circular arc larger than a semicircle, said resilient member being adapted to clamp said film rewound by said nip rollers and to take said film away from said spool holding means;
- storing means including a resilient member which clamps the outer periphery of said film being clamped by said gripping means, by means of a biasing force which is stronger than the biasing force applied by said gripping means, and takes away said film from said gripping means, said storing means being capable of storing a plurality of rewound films;
- and
- (e) shifting means which shifts said gripping means between a position where said gripping means opposes said spool holding means and a position where said gripping means opposes said storing means.
