Abstract
PURPOSE:To facilitate handling a camera, by detecting the increment of a torque load to switch the mode from a continuous film advancing mode to a rewinding mode. CONSTITUTION:A torque detecting lever 78 which is moved while interlocking with the movement of a patrone detecting lever 27 to the left due to a patrone 35 is detained by a detaining lever 74, and a motor is started by a contact piece 79 to turn torque detecting gears 71 and 72, and a film is advanced to the patrone 35. By the increment of a torque load for the completion of this continuous advancing, only the gear 72 is stopped. Then, the gear 72 rises through slopes 71b and 72b of respective parts to slide the lever 74, and the lever 78 where detention is released is moved to the left furthermore, and the motor is reversed by the contact piece 79. Therefore, parts of gears 72 and 71 engaged with each other again, and the film reaches a rewind initial position, and a switch is opened to stop the motor, and the photographic preparation is completed, and the mode is automatically switched from the continuous film advancing mode to the mode for rewinding one frame at every shutter operation, and thus the camera is handled easily.
