ABSTRACT:
A single drive source drives a pressing cam to selectively press a thermal head against a thermal transfer tape for printing on a recording paper behind the tape. The tape is divided into three longitudinal printing regions so the thermal head can be reciprocally moved forward, back and forward again respectively over the three regions of the tape before the tape is advanced to a new section. The drive source powers the reciprocating movement of the thermal head and the tape winding as well.
