US Patent 7477275 Thermal activation apparatus and printer

To smoothly transport a heat-sensitive adhesive sheet having a heat-sensitive adhesive layer on one surface, while a damage or peeling off of the heat-sensitive adhesive layer is suppressed. A thermal activation apparatus includes a thermal head for heating a heat-sensitive adhesive layer, a platen roller for thermal activation opposed to the thermal head, a guide member, and insertion rollers for transporting the heat-sensitive adhesive sheet. The guide member has a coating layer made of fluororesin, and the heat-sensitive adhesive layer before being thermally activated slides on the coating layer, whereby the heat-sensitive adhesive sheet is guided toward the thermal head for thermal activation and the platen roller for thermal activation.
