Claims

[Scope of utility model registration request]

The printing ribbon width is at least twice the character dimension in the width direction, two ribbon shafts 1 and 2 are provided at symmetrical positions with respect to a straight line passing through the printing center and perpendicular to the ribbon surface, and a single ribbon shaft that rotates in one direction is provided. A torque transmission claw 11 is provided on the inner surface of the ribbon shaft 1 that engages with the ribbon drive shaft at a constant height h from the cassette base surface 10 perpendicular to the ribbon shaft, so that when the cassette is reversed and set, the torque transmission claw 11 is attached to the ribbon drive shaft. A torque transmitting pawl 21 is provided on the inner surface of the mating ribbon shaft 2 at a height h from the cassette base surface 20 on the opposite side to the cassette base surface 10. Alternatively, a ribbon cassette is provided with a reel brake mechanism and a fitting portion on the outer shell that is compatible with a cassette holding mechanism corresponding to a printing device.
