Inventor: IWAYAMA TAKEYOSHI
IPC: B41J2/32
Filed: 1998-02-17
Abstract: PROBLEM TO BE SOLVED: To assure that erasing of an image on a reversible thermosensitive recording medium is completed when heating treatment of the recording medium is completed and the recording medium is taken out. SOLUTION: A heat sink 2 made of an aluminum plate is fitted to an opening on a top face of a housing body 1. A heater 3 which is energized by a control device 5 is attached to the rear face 2b of the heat sink 2. A shape-memory resin plate 7 is attached to the outer surface of the heat sink to cover the surface with a gap to which a reversible thermosensitive recording medium can be inserted. A friction coefficient of the surface of the shape-memory resin plate 7 becomes high under a temperature condition that an image on the reversible thermosensitive recording medium is erased and the friction coefficient thereof becomes low under the room temperature. As a result, when the heater 3 is heated in a condition that the reversible thermosensitive recording medium is inserted into the gap between the heat sink 2 and the shape-memory resin plate 7, the reversible thermosensitive recording medium can be pulled out by virtue of the friction against the shape-memory resin plate 7.
