Abstract

PURPOSE: To reduce the space of a winding spool by placing a planet gear which convers a rotation of the motor into that of the casing, into the space having the same size as the casing of the motor which has been formed as a winding spool.
CONSTITUTION: The outside circumference of the casing 9 of the motor operates as a film winding spool. Also, the first ring gear 304 and the casing 9 of the motor are formed in one body. Therefore, when the electric power is supplied to the motor, the disk 41 is rotated, but when the rotation of the disk 41 is fixed by making a stopper 34 go into the rotary locus of the pin 41a of the disk 41, the planet gear 302 rotates around the inside circumference of the first and second ring gears 304, 305 as the sun gear 301 rotates turns round on its own axis. In this case, if the second ring gear 305 is fixed, the first ring gear 304 rotates by the prescribed reduction gear ratio. Therefore, the casing is rotated, and the film can be wound. By means of said constitution, the space of the winding spool can be reduced.
