Abstract

In order to suppress adhesion and accumulation of a heat sensitive adhesive onto a thermal head from a trailing end portion in a transporting direction of a heat sensitive adhesive sheet, to thereby enable smooth and continuous transporting of a plurality of the heat sensitive adhesive sheets, a thermal head and transporting means are driven so that a plurality of heating elements of the thermal head are selectively operated in synchronization with timing of transporting of a heat sensitive adhesive sheet (2) by the transporting means. Thus, at least a part of the heat sensitive adhesive sheet (2) is heated to develop adhesive properties. When a trailing end portion (2b) in the transporting direction of the heat sensitive adhesive sheet (2) reaches a position at a predetermined distance (for example, 2 mm) before a position contacting with the heating element of the thermal head, heating by the thermal head is stopped. In addition, the transporting of the heat sensitive adhesive sheet is continued until at least the trailing end portion (2b) passes through the position contacting with the heating elements of the thermal head.
