Claims

[Scope of utility model registration request]

Supply spool 2 with ink ribbon 1 wound around it
In the ink ribbon cassette, which constitutes the traveling path of the ink ribbon from the ink ribbon to the take-up spool 3 via the contact point A with the recording head B of the recording device, during the traveling path of the ink ribbon 1, there is a contact point A between the supply spool 2 and the recording head B. On the way to the contact point A, the spring 4 is rotatably attached to the ink ribbon 1 and comes into contact with the ink ribbon 1 due to its spring force, and the spring 4 is configured to rotate while the frictional force with the ink ribbon 1 is increased. An ink ribbon cassette characterized in that a friction body 5 whose rotation is braked is installed.
