Summary: | A feeding tooth of a one-tooth sprocket retracts from a film so that the film can be prevented from being damaged by the feeding tooth of the one-tooth sprocket when the film is rewound. When a motor rotates in a film winding direction, a rewinding fork becomes free and a spool and the one-tooth sprocket rotates in a winding direction. As a result, the feeding tooth of the one-tooth sprocket engages with a perforation of the film to feed the end of the film up to the spool. On the other hand, when the motor rotates in the film rewinding direction, the one-tooth sprocket becomes free and the spool and the rewinding fork rotate in the rewinding direction. As a result, the film is wound around a rotation axis of a patrone. In this case, the feeding tooth of the one-tooth sprocket retracts from the film. |
