Abstract
A lamp house holds a light source, which is attached to a bottom plate. A film feed unit is arranged above the light source. A cartridge chamber is provided at the right of the unit body, and a film takeup chamber is formed at the left of the unit body. The takeup chamber is provided with a takeup spool. A film feed motor is built in the takeup spool, and the rotational force of the motor is transmitted to a spool driving shaft of the cartridge chamber via a driving force transmission mechanism. A film feed unit body to be incorporated into a camera is also used as a film feed unit body including the cartridge chamber, the takeup chamber and the driving force transmission mechanism. In order to observe the frame images on the film, the developed film is pulled out of a film cartridge mounted in the cartridge chamber.
