Thermal activation device

摘要

To provide a thermal activation device which enables reduced power consumption and reduced device volume while effecting a clear separation between an activation portion and a non-activation portion of a thermal activation label. The thermal activation device for heating a thermal activation sheet by using a thermal head having heat generating elements formed therein, including a radiator adapted to absorb and dissipate a heat of the thermal head and having a portion of the radiator arranged in contact with an introduction path along which the thermal activation sheet is introduced toward the thermal head, the portion of the radiator being brought into contact with the thermal activation sheet to effect preheating as the thermal activation sheet advances in the introduction path.
