Claims

[Scope of utility model registration request]

A thermal head is attached to a carriage that is movable in the direction of raising and lowering the digit, and a pinch roller and a driven pinch roller that narrow the ink ribbon between each other are provided on the lower side of the thermal head so that the ink ribbon can be moved close to and separated from the thermal head. A thermal transfer printer equipped with a ribbon guide for guiding an ink ribbon to a thermal head on a raised side, characterized in that the ends of the pinch roller, the driven pinch roller, and the ribbon guide in the ink ribbon installation direction are each tapered. printer.
