本発明は印字文字を修正する機能を備えた印字
装置に係わり、特に修正を良好ならしめる様にし
たものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a printing device having a function of correcting printed characters, and particularly to a printing device that allows correction to be performed well.
従来、記録紙上に印字された文字を修正するに
は、その文字の上に記録紙と同色のインク（通常
白色）を転写し、隠蔽させることにより行つてい

く、非常に印字品位を落とすものであつた。 Conventionally, characters printed on recording paper have been corrected by transferring ink of the same color as the recording paper (usually white) onto the characters to cover them up. This conventional example will be explained using figures. Figure 1 shows the characters printed on the recording paper, and the characters that should have been printed as A, B, C, D, and E were incorrectly printed as A, B, C, E, and E using a 5 x 7 dot matrix. However, this E should be corrected to D. To correct the printing error E, first cover up the gold dots in the 5×7 dot matrix with white ink. This state is shown in FIG. 2, where the dots indicated by diagonal lines in the upper right corner are the E dots that were misprinted, and the dots indicated by diagonal lines in the upper left corner are dots to which white ink was transferred. After hiding the erroneously printed E in this way with white ink, the correction is completed by printing D anew with black ink. However, with this method, erroneously printed characters are not necessarily corrected well, and the characters may be visible through the white ink, especially when erroneously printed characters are left blank in the hidden area. It was easy to see, and the quality of printing was greatly degraded.
本発明は上記欠点につきなされたものであり、
印字品位を劣化させることなく誤印字文字を修正

とを目的とする。 The present invention has been made to address the above-mentioned drawbacks,
An object of the present invention is to provide a thermal transfer printing device capable of correcting erroneously printed characters without deteriorating printing quality.

発熱素子と記録紙３間に装着する。 FIG. 3 shows a thermal transfer printing device according to an embodiment of the present invention, in which numeral 1 denotes a thermal transfer head, which is fixed to a carriage 2, and includes a printing ink ribbon 10 carrying black ink (FIG. 4) and recording paper. 3 pressed against the platen 4, it is guided by the guide shaft 5 and moves left and right. Belt 6 on carriage 2
is fixed to the shaft, and the rotational force of the motor 7 is transmitted to the carriage via the gear 8. As shown in FIG. 4, the thermal transfer head 1 has seven heating elements 9 arranged in the vertical direction, and predetermined ones of the heating elements are selectively and intermittently driven to produce a black color on the printing ink ribbon 10. The ink is melted and transferred onto the recording paper 3. More specifically, the black ink is composed of a heat-fusible material such as wax and a pigment such as carbon black, and when melted, it adheres to the recording paper and is peeled off from the base film for transfer. When the transfer is performed in this manner, the thermal transfer head moves at a constant speed, so dot-shaped characters are printed on the recording paper 3. When correcting printed characters, a correction ink ribbon (not shown) is attached between the heating element of the thermal transfer head 1 and the recording paper 3 instead of the printing ink ribbon 10.

隠蔽する力は飛躍的に向上する。 FIG. 5 is a block diagram of this embodiment. Reference numeral 11 is a circuit that detects the rotation of the gear 8 to detect the position of the carriage 2. The output of this detection circuit 11 causes the control circuit 12 to control the operation of the entire printing device. The driving timing of the heating element, the rotation of the motor 7, the feeding of the ink ribbon, the feeding of the recording paper, etc. are controlled. Reference numeral 13 denotes a driver circuit that drives the heating element 9 with timing determined by the control circuit 12, and is supplied with power by the power supply circuit 14. Reference numeral 15 denotes a switch for issuing a command to correct printing errors, and after pressing this switch, the number of digits to be corrected is specified using a keyboard section (not shown). As a result, the control circuit 12 moves the carriage to the designated digit, attaches a correction ink ribbon instead of the printing ink ribbon 10 to the printing position, and transfers white ink to all dots in the digit. At this time, the thermal transfer head 1 performs the transfer operation twice on the erroneously printed portion, and as shown in FIG. 6, two white ink layers 17 are formed on the black ink layer 16. When two (or three or more) white ink layers are formed on the black ink layer in this way, the ability of the white ink to hide the black ink is dramatically improved.
以上の様に本実施例は誤印字修正用スイツチに
応答して誤印字部に複数回修正用インクを転写す
る様にしたので、印字品位を劣化させることなく
誤印字の修正ができる。 As described above, in this embodiment, in response to the erroneous printing correction switch, the correction ink is transferred to the erroneously printed portion multiple times, so that erroneous printing can be corrected without deteriorating the print quality.
