THERMAL TRANSFER PRINTER

摘要

A thermal transfer printer comprises a frame, a printing mechanism, and a ribbon mechanism, wherein the frame comprises a base, and a ribbon bracket and an upper housing pivoted with the base through a respective pivot shaft thereof, wherein the frame further includes a linkage mechanism used to open the ribbon bracket in linkage when the upper housing is opened relative to the base, and a driven member fixedly connected with the ribbon bracket, and a rotation axis of the driven member is coaxial with a pivot shaft of the ribbon bracket; a rotational direction of the driving member is the same with a rotational direction of the driven member; an operating space for installing the ribbon is formed between the upper housing and the ribbon bracket when the upper housing is open.
