PURPOSE:To set always a winding load within a certain range, by arranging a projection, which has such height that it can be brought into contact with the outside face of a leading-out mouth of a cartridge, on the inside face of a rear cover which faces the film leading-out mouth of the cartridge loaded into a cartridge chamber of a camera body. CONSTITUTION:A projection 7 arranged on the inside face of a rear cover 6 which faces a film leading-out mouth 3a of a cartridge 3 loaded into a cartridge chamber 2 has such height l that it can be brought into contact with an outside face 3a' of the leading-out mouth of the cartridge 3. This height l is different by dimensions of the outside diameter of the cartridge, but it is desirable that the interval between a tip face 7a of the projection 7 and the outside face 3a' of the leading-out mouth 3a of the cartridge 3 is within a range of -0.3--0.7mm. as the cartridge 3 having a maximum diameter as the reference. That is, the projection 7 has the height to be brought into contact with the outside face 3a' of the leading-out mouth 3a of the cartridge 3 while pressing in slightly the outside face 3a'. |
