１３上に印字形成される。 When performing normal transfer recording on the recording paper 13, the ribbon selection device 14 is rotationally controlled by a drive motor (not shown) to hold the cassette 5 in a horizontal state as shown in FIG. In this state, both ribbons 6,
Of the 7, the recording transfer ribbon 6 is the thermal head 4.
A winding driving force is applied only to this recording transfer ribbon 6, which faces the heat generating portion of the recording transfer ribbon 6, and desired transfer recording is performed. That is, the recording paper 13 inserted into the apparatus along the paper guide 11 is transferred between the recording transfer ribbon 6 and the elastic body 9 of the platen 8 by the rolling of the paper feed roller 10 and the driven roller 12. The heat-melting ink on the recording transfer ribbon 6 is instantaneously melted and transferred onto the recording paper 13 by the heat generated by the thermal head 4. Therefore, the heat generating part of the thermal head 4 is selectively controlled and the carriage 3
By controlling the movement of the recording paper 13 along the guide shaft 2, desired characters, symbols, numbers, etc. are printed on the recording paper 13.

て消去される。 On the other hand, if erroneous printing occurs, the ribbon selection device 14 is rotated to hold the cassette in an inclined position as shown in FIG. In this state, the erasing transfer ribbon 7 faces the heat generating portion of the thermal head 4, and the winding driving force is applied only to this erasing transfer ribbon 7, thereby performing the desired lift-off.
That is, the heat-adhesive resin on the erasing transfer ribbon 7 is melted and adhered to the erroneous print area that was erroneously recorded on the recording paper 13 by the heat generated by the thermal head 4.
After the thermoadhesive resin cools, the erroneously printed portion is peeled off and erased.

残りのおそれはなくなる。 That is, FIG. 3 is a plan view showing the heat generating part of the thermal head 4, and FIG. 4 is an explanatory diagram showing the relationship between the recording paper 13 and the printing part recorded thereon. Reference numeral 4a denotes a resistive heating element divided into multiple parts in the height direction of printed characters. During normal recording, the resistive heating element 4a with a hatched width of W 1 is used, and when erasing erroneous printing, the resistive heating element 4a has a width of W 2 .
All resistance heating elements 4a are used, and W 1 < W 2
It is becoming. Therefore, during normal recording, the fourth
The heat-melting ink of the recording transfer ribbon 7 is transferred to part A shown by hatching in the figure, and when erasing erroneous printing, the heat-adhesive resin of the erasing transfer ribbon 7 is transferred to part B shown by the broken line in Fig. 4. The transferred portion B at the time of erasing completely encompasses the transferred portion A at the time of recording, and there is no possibility that the erased portion remains.

ヘツド４の長寿命化に効果がある。 Furthermore, when comparing the respective melting temperatures of the heat-melting ink of the recording transfer ribbon 6 and the heat-adhesive resin of the erasing transfer ribbon 7, the melting temperature of the heat-adhesive resin is generally higher; Erasing using the transfer ribbon 7 requires a larger heat generation capacity than recording using the recording transfer ribbon 6. Therefore,
The voltage supplied to each resistive heating element 4a of the thermal head 4 is controlled to be higher when erasing an erroneous print than during normal recording, so that heat is generated with a large power only during erasing. In this way, since the control means is provided to increase the power only during erasing, there is no need to particularly increase the power during normal recording, which is effective in extending the life of the thermal head 4.

可能である。 The transfer of the erasing transfer ribbon 7 at the time of erasing described above calls back the signal at the time of erroneous printing stored in a storage section (not shown), and applies heat only to the erroneously printed area recorded on the recording paper 13. It is also possible to lift off the erroneously printed portion by transferring an adhesive resin, or it is also possible to lift off the erroneously printed portion by transferring a thermal adhesive resin to the entire character surface including the erroneously printed portion.

Although the ribbon selection device 14 comprising a cam pin that engages with the ribbon selection device 14 has been described, the present invention is not limited to such a ribbon selection device 14, and a gear may be used to move the cassette 5 up and down. Furthermore, the movement of the cassette 5 is not limited to the rotational movement using one end as a fulcrum as in the above embodiment, but may also be moved up and down while remaining in a parallel state.
