Claims

[Claims for Utility Model Registration] An ink ribbon is sandwiched between a base fixed to the printer body and a plate movably attached to the base, and further attached to the base so that pressure can be applied to the plate. A ribbon brake device for a printing device that applies pressure to a plate by a spring applied to the ink ribbon, and applies tension to the ink ribbon by frictional force acting between the base and plate and the ink ribbon, the ribbon brake device having projections and grooves that engage with each other alternately. are provided at the ends of the ribbon running surfaces of the base and plate so as to guide the ribbon when the protrusions and grooves are engaged.
