A film transport system to be used in cameras for the Advanced Photo System cartridge film, which have one motor for feeding the film out of the cartridge and for taking up the film on the take-up spool, one sun gear with two planet gears in the film driving gear train to switch the direction of film drive between feed and take-up on the one hand and rewind on the other hand. An arc shaped slot receives the axle of the film advance (feed and take-up) planet gear to accommodate differences of speed between feeding and taking up of the film. This avoids the need for a one way clutch and a separate rewind gear train.
