Abstract
PURPOSE: To realize automation of film rewinding smoothly, by incorporating contacts in the film winding-up mechanism and forming a film rewinding start signal.
CONSTITUTION: A ratchet wheel 16 is secured to the end of a rotary shaft 2a of a drive motor 2 independently fixed in a spool 7 and it is linked with a gear 1 rotatably mounted on a camera main body opposedly provided thereto coaxially by means of a coil spring 17, and stop pins 16a, 1a, and contacts 16b, 1b are provided to the ratchet wheel 17 and gear 1, respectively. In this constitution, when the ratchet wheel 16 is rotated by the drive motor 2, the gear 1 is put into rotation through the coil spring 17, and the spool 7 also rotates by way of gear 3, 5, 6, thus winding up the film. When all the frames of the film are taken, the spool 7 can no longer rotate, and when the drive motor 2 is rotated by the completion of shutter action, the ratchet wheel 16 rotates largely, resisting the coil spring 17, and contact pins 16b, 1b contact with each other, so that a film rewinding start signal is inssued.
