As the platen roller for conveying the thermally active adhesive sheet having the thermally active adhesive layer on the backside of the recording surface of the sheet-like substrate, a platen roller is used which is subjected to a contact treatment to bring the surface of a roller portion into contact with a compound (a) containable as a solid plasticizer in the thermally active adhesive layer.

Abstract: Provided is a thermal activation device capable of preventing a heat-sensitive adhesive sheet from being partially excessively heated, keeping a short distance between a contact between a thermal head and a platen roller, and a discharge port, and preventing a structure of the thermal activation device from being complicated and a size thereof from increasing. While a heat-sensitive adhesive sheet (2) is transported along a transport path (15) through rotations of insertion rollers (3) and a platen roller (5), a heat-generating portion (4a) of the thermal head (4) is caused to generate heat, thereby thermally activating a heat-sensitive adhesive layer of the heat-sensitive adhesive sheet (2). When a trailing edge of the heat-sensitive adhesive sheet (2) reaches a position where the trailing edge thereof is not in contact with the platen roller (5), a transporting force is not transmitted to the heat-sensitive adhesive sheet (2), thereby stopping transportation thereof.
