Thermal activation device for heat-sensitive self-adhesive sheet and a printer using the same

摘要

Providing a thermal activation device for heat-sensitive self-adhesive label and a printer including the same, the thermal activation device accomplishing an easy and efficient thermal activation of a heat-sensitive adhesive layer by means of heating means and including cleaning means capable of readily removing remainders of heat-sensitive adhesive mass and the like transferred to the heating means. The thermal activation device for heat-sensitive self-adhesive label at least comprising heating means for thermal activation (51, 52) which activates by heating a heat-sensitive adhesive layer of a heat-sensitive self-adhesive sheet comprising a sheet-like substrate formed with a printable surface on one side thereof and with the heat-sensitive adhesive layer on the other side thereof; and conveyance means (53) which is disposed in opposing relation with the heating means for pressing the heat-sensitive self-adhesive sheet against the heating means and for conveying the heat-sensitive self-adhesive sheet in a predetermined direction, the thermal activation device further includes cleaning means (grooves S, projections P) for removing a heat-sensitive adhesive mass and its metamorphosed products remaining on the heating means for thermal activation.
