Thermal activation apparatus and printer including the same

摘要

Provided is a thermal activation apparatus in which a discharge path of a heat-sensitive adhesive label is not adversely affected by adhesive residue. The thermal activation apparatus includes a discharge roller (5) for completely discharging a heat-sensitive adhesive label with its heat-sensitive adhesive agent layer formed on the back side that is heated by a thermal head from between the thermal head and a platen roller. Grooves (53) are formed along the circumferential direction of the discharge roller 5 at places which correspond to the lateral edges of various kinds of heat-sensitive adhesive labels.
