ABSTRACT:
An apparatus for thermally activating a heat-sensitive adhesive sheet of the type having a printable surface on one side, a heat-sensitive adhesive layer on the other side and sheet identifying information including information concerning one or more properties of the adhesive used in the adhesive layer, comprises an energizeable heating unit for heating the heat-sensitive adhesive layer to activate the same, a reading sensor for reading the sheet identifying information, and a control section for controlling energy applied to the heating unit on the basis of the sheet identifying information read by the reading sensor. The control section controls the energy applied to the heating unit by keeping the amplitude of applied voltage pulses constant and varying the pulse width. An ambient-temperature measuring sensor measures temperature in the vicinity of the heating unit and the control section controls the energy applied to the heating unit on the basis of the temperature measured by the ambient-temperature measuring sensor.
