ABSTRACT:
A thermal transfer printer with an erasing function for recording data by use of heating energy. Included are a signal generator to generate a signal to instruct the erasure; a heating energy generator; a memory in which generation patterns of heating energy to be generated from the heating energy generator are stored; and a controller to control the heating energy generator in a manner such that a plurality of different generation patterns are read out of the memory on the basis of the erasing instruction from the signal generator and different heating energy is generated from the heating energy generator a plurality of times on the basis of the generation patterns, thereby erasing recorded patterns. The heating energy generator gives the heating energy to the recorded patterns through a correctable ribbon which can print and erase. With this printer, the data recorded by variable lengths in the proportional spacing mode can be certainly erased.
