Abstract
PURPOSE:To eliminate a failure in photography and to facilitate operation by providing an automatic rewinding device which starts continuous rewinding automatically when a photographic film is all exposed. CONSTITUTION:When a patrone is not loaded, a patrone detection lever 37 is drawn by a spring 91, so a pin 37a on the detection lever 37 is freed to draw a changeover knob 39 by a spring 41, so that switches 40' and 40'' which are changed over by a contact piece 40 come into contact with contacts 40'b and 40''b. When a shutter button is pressed in this state, a switch 44 is closed and after AF and the operation of a shutter, a film constant-length advancing motor control switch 45 is turned on to rotate a motor clockwise. Then, a gear 4 also rotates clockwise and a sprocket 19 and a friction roller 32 rotate in a rewinding direction. Simultaneously, the shutter operation and AF charging are performed and once a film constant-length advancing mechanism rotates once, the switch 45 is turned off to brake the motor.
