    摘要: A motor-driven film winder for a camera has an internal gear portion (5a) fixed to a motor (1), one or two step-shaped planet gears (7), (8) having first gears (7a), (8a) to mesh with a pinion gear (4) driven by the motor and the internal gear portion (5a) and second gears (7b), (8b) having a larger diameter than first gears (7a), (8b), and engaging with an internal gear (11a) provided on inside wall of the take-up spool (11), whereby rotation of the motor is transmitted to the take-up spool (11) with largely reduced speed of rotation and largely multiplied torque.
