ABSTRACT:
A fan-folded type ink ribbon cartridge in which an ink ribbon is regularly folded to have a constant width and is enclosed in an enclosing space of a cartridge casing. This cartridge is provided with a plurality of projections which are arranged to face one another on the mutually facing inner surfaces of the cartridge casing near the outlet of the enclosing space of the cartridge casing. Each gap which is formed by the projections facing each other is set to be more narrow than the folding width of the ink ribbon. These gaps may be set to be constant or they may be set so as to gradually become more narrow towards the outlet of the enclosing space. The ink ribbon is hooked by the projections and the folding width is gradually reduced, so that the ink ribbon can be stably pulled out with minimal load variation. In addition, the ink ribbon is prevented from falling down due to the pressure of the inlet side of the enclosing space or due to the weight of the ribbon itself.
