ABSTRACT:
In order to provide a thermal printer, which can reliably pressure-contact a recording paper made of thick paper to a platen roller with a small motor and print high quality images, a thermal printer of the invention includes head supporting members, which support a thermal head to head up/down with respect to a platen roller; and a guide member capable of pressure-contacting a recording paper conveyed between the thermal head and the platen roller to the platen roller. The thermal head can head up/down when the head supporting members turn. The guide member is separated from the head supporting members, thereby the guide member ascends and descends with respect to the platen roller by a driving source (not shown) capable of turning the head supporting members.
