FILM WINDING DEVICE OF CAMERA

PURPOSE:To make a winding stop position accurate by providing a gear row, which transmits the rotatory force of a motor to a film take-up spool, and a detaining member which detains rotation of the spool when a counting means counts the number of perforations corresponding to the length of one frame of a film. CONSTITUTION:When a motor 2 is driven by a control circuit 15, this driving force is transmitted to a spool 7 through a ratchet 16, a coil spring 17, and the gera row consisting of gears 1, 3, 5, and 6 and rotates the spool 7 to wind up a film 10. When passage of a prescribed number of perforations 10a is detected by the counter, that is, when one-frame components of the film 10 are wound up, an electromagnet 14 is made inactive through a control circuit 15 by a signal from the counter. Then, a rotating claw 12 is turned by a spring 13 and is engaged with the gear 3, and rotation is stopped, and meanwhile, this control circuit 15 stops power supply to the motor before the electromagnet 14 is made inactive, thus terminating the winding operation of the film 10.
