Abstract: A thermal activation method for a heat-sensitive adhesive sheet having a front end and a rear end. A heat-sensitive adhesive sheet is conveyed between a thermal head for generating heat and a platen roller by rotating the platen roller against the thermal head to thermally activate the heat-sensitive adhesive sheet. The thermal head is driven to cause the thermal head to generate heat in synchronization with conveyance of the heat-sensitive adhesive sheet by the platen roller so that the thermal head starts generating heat before the front end of the heat-sensitive adhesive sheet enters between the thermal head and the platen roller and while the platen roller rotates less than once between the point at which the thermal head starts generating heat and the point at which the front end of the heat-sensitive adhesive sheet enters between the thermal head and the platen roller.

Abstract: A heat-sensitive adhesive layer is thermally activated to develop satisfactory adhesion at improved energy efficiency. A thermal activation thermal head is driven in sync with movement of a heat-sensitive adhesive sheet conveyed, and chosen heating elements stop being driven at a given timing. For instance, while moving the heat-sensitive adhesive sheet, driving of three heating elements (10B, 10F and 10J) and driving of two heating elements (10D and 10H) are alternately stopped whereas five heating elements (10A, 10C, 10E, 10G and 10I) are driven all the time. Supposing that the entire surface of a heat-sensitive adhesive layer is gridded to form a matrix, a region (15A) that is directly heated by none of the opposing heating elements 10 is placed regularly in a manner that makes its surrounding regions (15B to 15I) heated directly by the opposing heating elements.

Abstract: A printer comprises a frame having a pair of side walls spaced apart a given distance according to a given width size of a recording medium. A platen is supported between the pair of side walls and has a surface for supporting the recording medium. A printhead, operable in a printing position thereof to perform a printing operation on the recording medium, is supported between the side walls for tilting movement and displacement in forward/backward and rightward/leftward directions. A pressing body is supported by the frame for pressing the printhead into contact with the surface of the platen. When the printhead is in the printing position, the printhead is freely pivotable to permit automatic angular adjustment thereof following the surface of the platen so that the printhead can contact the surface of the platen with a uniform surface pressure.
