ABSTRACT:
The present invention relates to a camera having a spool drive mechanism for pushing film loaded in a film cassette out of the cassette by rotating a spool. Herein, after a film cassette is mounted, when film is to be pushed out of the film cassette, a drive motor is rotated counterclockwise. A one-way clutch then couples a first pulley gear with a spool drive shaft, thus allowing the spool drive shaft to eject film. For rewinding film into the film cassette, the drive motor is rotated clockwise. This causes a pair of clutch elements to couple a helical gear with the spool drive shaft via the first pulley gear. Film is then rewound.
