A dry battery includes a cylindrical housing, a first end plate and an electrode. The electrode protrudes from the first end plate and includes a tip end plate and a cylindrical side wall. The cylindrical housing, the first end plate, the tipe end plate and the cylindrical side wall each made of a conductive material are electically connected with each other so as to form a first conductive surface. A first contactor of an electrical power source circuit is arranged to come in contact with a part of the first conductive surface other than the tip end plate.

Cylindrical type dry battery and battery chamber

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.
