Abstract
A braking mechanism which applies tension to an ink ribbon is provided. The braking mechanism comprises: a first friction member which is fitted to a supply shaft to rotate and support the ink ribbon and is rotated as one body together with the supply shaft; a second friction member which is fitted to the supply shaft in such a way that relative rotation can be realized and for which absolute rotation at least in one direction is restricted and relative axial movement to the supply shaft can be realized; an operation member which is screwed into a screwed section formed on the supply shaft; and an energizing member which is arranged between the operation member and the second friction member and which presses the second friction member for energizing the second friction member.
