<p><P>PROBLEM TO BE SOLVED: To provide a device and a method for erasing information of a reversible thermal medium in which the erasing time can be shortened by shortening the time required for reaching a "discoloring temperature region", required capacity of power supply can be reduced, deformation and deterioration of the thermal medium can be suppressed, a part of the thermal medium or the entire surface thereof can be heated appropriately, and partial underheating or overheating can be prevented. <P>SOLUTION: The information erasing device comprises a rod-like continuous light emitting source 12, a condensing optical system 14 and a scanning mechanism 16. Light 1 is condensed as a linear light 2 which is used for scanning a thermal medium 3 in the width direction. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
