A film feeder for cameras comprises a drive shaft for driving a film cartridge which is engaged with a spool shaft of the film cartridge to rotationally drive the spool in the forward direction or the reverse direction, thereby rotationally driving the spool in the film lead-out direction or in the film rewinding direction, respectively; an electric motor for rotationally driving the foregoing drive shaft and capable of rotating forwardly or reversely; a rotation transmission system for transmitting a rotational force derived from the motor; and a switch device for selecting either of two transmission paths for driving the drive shaft of the cartridge in compliance with the rotational direction imparted by the motor.
