Description

[Detailed Description of the Invention] ``Industrial application field failure 1'' is 01il? The present invention relates to a printing device used in word processors, typewriters, etc., which prints characters and figures using a thermal transfer method.

Conventional configurations and their problems In recent years, with the advancement of MicroEllen 1-ronics, printing devices such as word processors and typewriters have become lighter and more compact, and demands for high-definition characters, figures, tabulations, etc. are increasing day by day. There are nine. Therefore, printing devices using thermal transfer or thermal sublimation methods have become widespread.

However, conventional printing devices have never been satisfactory in terms of correction of typographical errors q:.

Figure 1 shows the principle of thermal transfer. , is a map.

In FIG. 1, 1 is a thermal head having a plurality of heating resistive elements 1a, 2 is a paper (plain paper) wound around a platen 3, and 4 is a band-shaped thermal transfer ink filler. etc. film-like base 4shi 4a and base month 4
It consists of a hot melt ink 4b applied to all. Zamarhenod 1, admonishing the structure as shown below.
When electric current B- is applied to the heating resistive element 1a, the heating resistive element 1a generates heat to melt the band-shaped thermal transfer ink film 4b and transfer it to the transfer paper 2, thereby performing the desired printing.

This is the principle of thermal transfer (thermal melting).

A case of correcting printed characters or figures based on the above principle will be explained based on the drawings. FIG. 2 shows a schematic diagram of the main parts of a conventional printing and correction method.

In Fig. 2a, 4 is a band-shaped thermal transfer ink film, in which black ink for printing and white ink for correction (denoted as J2BK and W in the drawings, respectively) are applied at regular intervals in the longitudinal direction. It is painted. 1 is a thermal head, and 2 is a transfer paper (plain paper) 3 is a platen around which the transfer paper 2 is wound.

Here, when printing data is input by key input or the like, a voltage is intermittently applied to the heating resistor element of the thermal head 10, and the thermal head 1 is further scanned in the direction of the arrow α to inject the required ink onto the thermal transfer ink film 40. is thermally melted and printed on the transfer paper 2. At this time, the thermal transfer ink film 4 that has been consumed is wound up in the direction of the arrow γ. When monochrome printing is performed as described above and one line of printing is completed, the transfer paper 2 is fed in the direction of the arrow β by the platen 3 and the paper feeder 141j (not shown).

FIGS. 2C and 2C are sectional views of main parts for explaining printing and correction operations. As shown in FIG. 2, according to the principle explained in FIG. 1, black printing is performed by inputting print data by key person Kani γ. After this, if you find that the printed characters or figures are not what you want, and you want to correct them, use the same method as above to correct the size using the white ink part of the thermal transfer ink film 4, as shown in Figure 2C. By overlapping and transferring the black ink printed on the black ink, the correction is made to the white color A'11. After that, the new printing data is input again and the corrected part is printed again.

However, in the above configuration, the thermal transfer ink film 4 is coated with white and black ink at regular intervals in the longitudinal direction, so if there are few corrections, the white ink will be wasted and the thermal transfer ink film 4 will be consumed. increases,
This method has disadvantages in that the printing cost is high, which imposes a large cost burden on consumers, and the printing speed decreases because it is necessary to skip the black ink in the middle and locate the beginning of the white ink section.

The present invention solves the above-mentioned drawbacks of the conventional technology, and has a simple configuration that greatly reduces the consumption of thermal transfer ink film that eliminates white ink for correction, and also improves printing speed. The purpose of the printing device of the present invention is to provide a printing device such as a word processor or a quiwriter that can easily correct printing without causing deterioration. A white heat melting or heat gel for printing correction 1. A first ink layer on which a florescent ink is formed, and the first ink layer. The system includes a thermal transfer ink film formed with a second ink layer containing sublimable ink, and a thermal head that transfers the ink of the thermal transfer ink film onto recording paper wound around a platen. , the voltage applied to the heating resistor element of the thermal head is set to W1'lJ, and the amount of heat generated by the thermal head is controlled in two stages to selectively apply the first ink layer or the second ink layer. It can be printed or corrected by thermal melting (or thermal sublimation) on the transfer paper.

The relationship between 1) and (2) creates a barrier, and black printing is performed as shown in the tertiary Na. After this, it should be noted that the printed character 2 figure ': 9 is not the required one, so if you want to correct this, use the correction white color of the first layer 5b of the thermal transfer ink film 5 as shown in Figure 3. Thermal energy for thermally melting the ink and further thermally melting the boundary layer 6C is transferred to the heating resistor element 8a of the thermal heel I-'8.
