前部両側に形成されている。Embodiment An embodiment of the present invention will be described with reference to FIGS. The same parts as those described in FIGS. 4 to 6 are designated by the same reference numerals, and the description thereof will be omitted. Projecting pieces 18 are formed on both sides of the front portion of the cassette case 5 on the arm 9 side, and fitting portions 19 to which these protruding pieces 18 are fitted are formed on both front portions of the ribbon base 1.

用紙16に触れて用紙16を汚すようなことはない。In such a configuration, when the front portion of the ribbon cassette 4 is placed on the ribbon base 1 and the projection 10 is inserted into the guide groove 2, the bending piece 3 is engaged with the locking claw 11 and the projection piece 18 is fitted. Fit into the joint 19. As a result, the ribbon base 4 is positioned in the left-right direction by fitting the protrusion 10 and the guide groove 2 and fitting the protrusion 18 and the fitting portion 19, and the locking claw 11 and the bending piece 3 are also provided.
By engaging with, the retainer in the insertion direction is prevented. Further, since the locking claws 11 abut on the rear portion of the rear surface of the ribbon base 1, the rear portion of the cassette case 5 does not float from the ribbon base 1, and the protrusion 18 is pressed to the ribbon base 1 side by the fitting portion 19. Therefore, the cassette case 5 is entirely held in close contact with the surface of the ribbon base 1.
Therefore, the ink ribbon 6 pulled out between the arms 9 is always located at a fixed position, and the portion other than the portion to be printed does not touch the paper 16 and stain the paper 16.

することができる効果を有する。Since the present invention is configured as described above, the cassette case is positioned with respect to the ribbon base by fitting the guide groove and the protrusion, and the cassette case is positioned by the engagement of the locking claw and the locking portion. The locking of the cassette case against the ribbon base is prevented by preventing the detachment in the insertion direction and preventing the rear part of the cassette case from floating with respect to the ribbon base by abutting the locking claw on the back surface of the ribbon base. It is possible to prevent the front part of the printer from floating, thus avoiding a situation in which the ink ribbon pulled out to the printing unit is positioned at a fixed position and the ink ribbon inadvertently contacts the paper and stains the paper. Has the effect of being able to.
