Thermally activating apparatus and printer for heat-sensitive adhesive sheet

摘要

To provide a thermally activating apparatus and a printer for a heat-sensitive adhesive sheet capable of preventing adhesive of a heat-sensitive adhesive sheet from being carbonized to be fixed on the surface of a thermal head to improve efficiency of energy transmission to the adhesive and invariably exhibiting a desired bonding property by optimally controlling energy to be applied. In a thermally activating apparatus for a heat-sensitive adhesive sheet comprising at least a thermally activating heating means for heating to activate a heat-sensitive adhesive layer of the heat-sensitive adhesive sheet, the adhesive sheet having a printable surface formed on one side of a sheet-like substrate thereof and having the heat-sensitive adhesive layer on the other side, there is provided an energy control means for controlling energy to be applied to the thermally activating heating means by keeping the amplitude of the applied voltage pulse constant and varying the pulse width.
