PURPOSE:To facilitate the operation of a camera by releasing the stop of a changeover switch from a continuous winding to rewinding when a patrone is taken out of the camera. CONSTITUTION:When a patrone is not loaded, a patrone detection lever 37 is drawn by a spring 91 to rotate clockwise, so a pin 37a provided 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 release button is pressed in this state, a switch 44 is closed, and a member operating in engagement with the closing operation of a shutter moves the tip of a constant-length advancing ever 95 in a direction B after AF and the operation of the shutter to close a control switch 45 for a film constant-length advancing motor, thereby starting a switch 45'. Consequently, the motor rotates clockwise and a gear 4 also rotates clockwise to rotate a lever 5 clockwise, thereby rotating a sprocket and a friction roller in a rewinding direction. |
