Claims

[Scope of Claim for Utility Model Registration] A driving wheel and a driven wheel are rotatably arranged opposite to each other in a cassette, an ink ribbon is sandwiched between the driving wheel and the driven wheel, and an ink replenishing part is brought into contact with the driving wheel or the driven wheel, In the ink ribbon cassette in which the ink ribbon is run by the rotation of the driving wheel, and the ink replenishing section supplies ink to the driving wheel or the driven wheel to replenish the ink ribbon, the driving wheel presses against the printing area of the ink ribbon and the upper part thereof. The ink replenishing part is brought into contact with the ink ribbon pressing part of the car or driven car, and at least the diameter of the driving car or driven car that presses against the printing area of the ink ribbon is made larger than the diameter that presses outside the printing area of the ink ribbon. Features an ink ribbon cassette.
