PROBLEM TO BE SOLVED: To improve incorporation workability by forming a bearing part in a nearly semicylindrical shape opened at the upper side, and forming an elastic member of a leaf spring that can be incorporated from above a lower shell. ;SOLUTION: A feed spool 30 and a wind spool 40 are stored in a manner to be rotatable inside a cartridge main body 2 constituted of an assembly of a lower shell 10 and an upper shell 20. An ink ribbon 50 is wound to each spool 30, 40. A small-diameter axial part at one leading end 36, 46 is inserted to a bearing part 18a, 18b of the lower shell 10 to be supported rotatably. A metallic leaf spring 61, 61 as an elastic member is inserted to the bearing part 18a, 18b, so that each spool 30, 40 is pressed in an axial direction by an elastic bias force of the leaf spring and prevented from rotating idle. A slack of the ink ribbon 50 is accordingly prohibited. Since the leaf springs 61, 61 and spools 30, 40 can be incorporated with the lower shell 10 from above, workability is considerably good.;COPYRIGHT: (C)1998,JPO
