A thermally activating apparatus of a thermosensible adhering sheet at least
having
a thermally activating thermal head, a thermally activating platen roller and controlling
means for controlling to process to drive these, having heating means (for example,
thermally activating thermal head) for applying thermal energy to a remaining substance
comprising a thermosensible adhesive or a denatured substance thereof or the like
adhered to a thermally activating thermal head and a thermally activating platen
roller, and carrying means (for example, thermally activating platen roller) capable
of carrying a predetermined cleaning sheet by inserting the predetermined cleaning
sheet into the thermally activating apparatus from a predetermined direction, in
which the controlling means is constituted to be able to control to process to
drive the heating means and the carrying means, the thermal energy is applied to
the remaining substance by making the heating means generate heat in a state in
which the thermosensible adhering sheet is not disposed between the thermally activating
thermal head and the thermally activating platen roller, and the thermally activated
remaining substance is transcribed onto the cleaning sheet to remove by carrying
the cleaning sheet between the thermally activating thermal head and the thermally
activating platen roller by operating the carrying means.
