DISCLOSURE OF THE INVENTION In the above prior art,
When the image recording card display section is partially changed, there is a problem that the entire display section is erased and only the changed section cannot be partially erased. In addition, when printing, the entire display is erased, so there is a portion that overlaps with the display before erasing, which reduces the efficiency of editing work, and the use of the thermal head and image recording card is more than necessary. There is a problem in that the frequency is inevitably reduced and the durability of the thermal head and the image recording card is significantly impaired. In addition, there is a problem that a grace period is required until the temperature of the one-sided or double-sided heating element for erasing the display unit reaches a temperature at which the character can be erased when the above-mentioned device is activated. The present invention aims to solve the above problems.
