PURPOSE:To reduce the total weight of a camera body by making a mirror box and a buttom wall of a metal by press formation, and then by constituting the camera body by inserting the metal part partially into a plastic part which forms a film storage room, a film take-up room and a front plate part between the two. CONSTITUTION:A film storage room 61, a film take-up room 62, and a front plate part 63 are made of plastic, and a mirror box and a bottom wall 4 are formed of a metal in one body to constitute a camera body 1 by the metal part 7 and plastic part 6. The metal part 7 has a fitting part (composed of fitting holes 2a-2d) for a side wall plate 2 equipped with an aperture and a mount fitting part (composed of fitting holes 9k, 10k, 12b, and 12c) for a photographic lens, and the metal part 7 on the mount fitting side is inserted as a frame partially into the plastic part 6 together with the bottom wall 4 to obtain a body of stiff structure. |
