Abstract
A photographic film is previously wound around a spool in a scroll chamber to be ready for photographing. The film is wound by one frame when a film winding knob is operated. After all the frames have been exposed, it is wound back to a film magazine in a film magazine chamber. The film magazine in which the film has been wound, is taken out from the film magazine chamber when a rear cover is folded at a groove portion provided on the rear cover after at least one of the three engaging hook portions between the rear cover and the film unit body has been disengaged.
