PURPOSE:To obtain a device which is high in accuracy and light in weight, by inserting a metallic block between a film store chamber and a film winding chamber which have been formed by use of plastic, so as to form them in one body. CONSTITUTION:As for a plastic part 1 for forming a film storing chamber 11 and a film winding chamber 12, for instance, its parts 13, 14 are made to tightly adhere to both upper and lower end parts of a metallic block 2, and the film storing chamber 11 and the film winding chamber 12 are connected. As for the metallic block 2 to be inserted, for instance, the greater part of the inside surface and the reverse surface part is exposed without embedding the block, so that strength against the thin plastic part can be secured. The metallic block 2 is molded by press work, and is formed in one body by surrounding the outside circumference of an aluminum alloy 3 provided with an aperture for prescribing the size of a picture, by a front plate mounting part, for instance, a zinc alloy 3 of zinc die castings, provided with mounting holes 4a-4d. |
