US 2011/0216145 A1 · PRINTER, METHOD FOR RELEASING PRESSURE CONTACT OF HEATING BODY

Abstract

A printer includes a conveying unit for conveying a rewritable printing medium toward a discharging portion along a conveying path, and the rewritable printing medium is erasable and printable by applying heat energy to the rewritable printing medium. The printer further includes an erasing unit including a heating body for erasing print of the rewritable printing medium by pressing the heating body to be in pressure contact with the rewritable printing medium, a printing unit for printing the rewritable printing medium, a determination unit for determining whether an abnormality occurs in conveyance of the rewritable printing medium, and a control unit for controlling at least one of the erasing unit and the conveying unit for releasing the pressure contact of the heating body on the rewritable printing medium, if the determination unit determines that an abnormality occurs.

Dependent claims

A printer comprising:

a conveying unit configured to convey a rewritable printing medium along a conveying path, the rewritable printing medium being erasable and printable by applying heat energy to the rewritable printing medium;
an erasing unit including a heating body, the erasing unit configured to erase print of the rewritable printing medium by pressing the heating body to be in pressure contact with the rewritable printing medium;
a printing unit located on a downstream side of the erasing unit along the conveying path, the printing unit configured to print the rewritable printing medium by applying heat energy to the rewritable printing medium;
a determination unit configured to determine whether an abnormality occurs in conveyance of the rewritable printing medium;
and
a control unit configured to control at least one of the erasing unit and the conveying unit for releasing the pressure contact of the heating body on the rewritable printing medium, if the determination unit determines that an abnormality occurs.
