Claims

[Scope of utility model registration request]

A thermal head in which a large number of heating elements are linearly arranged is pressed against a platen roller by the elastic force of a spring member, and ink from a thermal ink film supplied between the thermal head and the platen roller is transferred to the heating elements. In a thermal transfer printer configured to transfer images onto a recording paper using heat, a holding means for movably holding the thermal head;
a pressure contact means for pressing the thermal head against the platen roller; and a pressure adjustment means for adjusting the elastic force of the spring member; the thermal head is brought into pressure contact with the platen roller at a substantially limit position by the pressure contact means; A thermal transfer printer characterized in that the elastic force of the spring member of the pressure adjusting means is transmitted to the thermal head.
