Filed: 2002-06-05
Abstract: <P>PROBLEM TO BE SOLVED: To suppress residual visible data due to foreign substances sticking to the surface of a heating element of a thermal head.  <P>SOLUTION: When rewriting of visible data reaches the predetermined number (S2), an apparatus judges that the heating element of the thermal head is soiled by foreign substances (S5), and deletes (S6-S8) the visible data displayed on a heat sensitive layer by the preset number of times of deletion (S3) within the rewriting range of the visible data, and rewrites new visible data (S10). By this method, because at least one deleting process is carried out for every predetermined number of rewriting of the visible data, the foreign substances stuck on the surface of the heating element are softened and easily moved to a rewrite card, and its cleaning is carried out. On the other hand, the foreign substances stick to the rewrite card. However, because sticking positions of the foreign substances are changed by execution of the delete process, generation of residual visible data at a specific part can be suppressed.  <P>COPYRIGHT: (C)2004,JPO
