Thermal activation method and processing method for a heat-sensitive adhesive sheet, thermal activation device for a heat-sensitive adhesive sheet, and printer for a heat-sensitive adhesive sheet

摘要

A heat-sensitive adhesive sheet is thermally activated thoroughly at both ends in a conveying direction and unnecessary heating from heat accumulated in a platen roller is avoided. Driving of heating elements ( 10 ) of a thermal activation thermal head is started (T 3 ) before the front end of a heat-sensitive adhesive sheet ( 1 ) in a sheet conveying direction enters between the thermal head and a platen roller ( 12 ) (T 2 ). A heat-sensitive adhesive layer is thermally activated until the heat-sensitive adhesive sheet is sent past the heat-sensitive adhesive sheet ( 1 ). Driving of the heating elements ( 10 ) is stopped (T 6 ) after the rear end of the heat-sensitive adhesive sheet ( 1 ) departs from between the thermal head and the platen roller 12 (T 5 ). The time period from the start of driving of the heating elements ( 10 ) to the entrance of the front end of the heat-sensitive adhesive sheet ( 1 ) between the thermal head and the platen roller ( 12 ) (T 2 -T 3 ), and the time period from the departure of the rear end from between the thermal head and the platen roller ( 12 ) to the end of driving of the heating elements ( 10 ) (T 6 -T 5 ), are each set shorter than the one it takes for the platen roller ( 12 ) to rotate once.
