• (b) loading an unexposed photographic film, to a main body of the lens-fitted film unit;
• and
• (c) attaching the rear cover to the lens-fitted film unit;
• wherein the lens-fitted film unit has the main body, a front cover and the rear cover for covering the main body, wherein the main body has a magazine chamber for accommodating the magazine to store the photographic film, and an unexposed film chamber in which the unexposed photographic film has been stored in advance;
• wherein the lens-fitted film unit has a magazine chamber lid provided on a bottom surface of the lens-fitted film unit and below the magazine chamber from which the magazine is removed through the magazine chamber lid, wherein the front cover, the rear cover and the main body have respective ribs, and a periphery of a lower portion of the magazine chamber is surrounded by the respective ribs of the front cover, the rear cover and the main body;
• and
• (d) mounting the magazine chamber lid to the lens-fitted film unit after attaching the rear cover so that a side wall portion of the magazine chamber lid is located outside the respective ribs of the front cover, the rear cover and the main body, and mounting the magazine chamber lid so that the magazine chamber lid is fixed to at least one of the front cover and the rear cover, and is not fixed to the main body.
