Abstract
A cartridge comprises a shutter for opening and closing an opening portion formed on a ceiling plate of an upper side member. The shutter slides on an outer surface of the ceiling plate by attaching and detaching the cartridge. Lifter projections are projected on a back portion of a lifter provided in the cartridge. The lifter projections are projected to an outer section through an opening portion formed on a bottom plate of a lower side member. If the cartridge is put on the plane, the lifter projections are pressed to an interior, so that the lifter is pushed up. Thereby, a recording paper is pressed onto the back surface of the ceiling plate. As a result, a space of the cartridge is lessened, the flow of air from the outer section is reduced, and a variation in internal moisture is controlled.
