Patent number: RE36246Abstract: A film rewinder for a camera comprising a motor and rewinding means driven by the motor and adapted to rewind a used film into a film cartridge, comprises first sensing means disposed at a specific position in the path of the film moved to the film cartridge when the film is being rewound and effective to generate an output signal when the leader portion of the film has passed the specific position; second sensing means effective to generate an output signal when the leader portion of the film is further rewound to the film cartridge beyond the specific position; means for selecting one of first and second conditions; and control means. The control means is used for de-energizing the motor when the first condition is selected by the selecting means and if the control means receives the output signal from the first sensing means and for de-energizing the motor when the second condition is selected by the selecting means and if the control means receives the output signal from the second sensing means.Type: GrantFiled: October 18, 1996Date of Patent: July 6, 1999Assignee: Nikon CorporationInventors: Yoshiyuki Nakano, Mikio Takemae
