Patent ID: 7477275

Claim:
A thermal activation apparatus, comprising: a thermal head for thermally activating a heat-sensitive adhesive layer of a heat-sensitive adhesive sheet, the heat-sensitive adhesive sheet having the heat-sensitive adhesive layer on one side of a sheet-like substrate; a platen for thermal activation which is placed in opposition to the thermal head and which allows the heat-sensitive adhesive sheet to travel between the thermal head and the platen; a guide member for guiding the heat-sensitive adhesive sheet between the thermal head and the platen roller, the guide member being placed on an upstream side of the thermal head and the platen with respect to a transporting direction of the heat-sensitive adhesive sheet, and the guide member having at least a portion formed from fluororesin that comes into contact with the heat-sensitive adhesive layer of the heat-sensitive adhesive sheet to guide the heat-sensitive adhesive sheet; and a pair of insertion rollers placed on an upstream side of the guide member with respect to the transporting direction of the heat-sensitive adhesive sheet and which sandwich therebetween the heat-sensitive adhesive sheet for delivering the heat-sensitive adhesive sheet between the thermal head and the platen.
