Thermal transfer printer

A thermal transfer printer with a configuration comprising an ink ribbon supply section, an ink ribbon winding section, onto which an ink ribbon that has been sent from said ink ribbon supply section is wound after passing between a thermal head and a platen, and a braking mechanism which applies tension to said ink ribbon at said ink ribbon supply section, wherein

• said braking mechanism comprises:
• a first friction member which is fitted to a supply shaft to rotate and support said ink ribbon and is rotated as one body together with the supply shaft;
• a second friction member which is fitted to said 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 said supply shaft can be realized;
• an operation member which is screwed into a screwed section formed on said supply shaft;
• and
• an energizing member which is arranged between said operation member and said second friction member and which presses said second friction member for energizing said second friction member, and
• said energizing member changes the energizing force for said second friction member by adjusting a screwed position of said operation member to said screwed section on said supply shaft.
