Note that the CPU 1 controls the winding of the ink ribbon 41 and feeding the necessary colored parts to the thermal head 43, the transport of the key A ridge 47, and the paper feed of the printing paper 44.
Based on the control code sent from 1, an intelligent printer control circuit 16 processes it. Further, the line memory 15 stores characters and the like displayed on the liquid crystal panel 3 in the form of dot patterns, and the panel drive circuit 18 displays the contents of the line markings 15 on the liquid crystal panel 3 as they are. That is, the liquid crystal panel 3
The display is performed using a so-called bitmap display method.

Next, among the processes performed in the above-mentioned electronic control device 10, particularly the character input display process that involves designation of a print color will be explained with reference to the flowchart shown in FIG.

When the document editing apparatus of this embodiment is powered on, a document to be input/edited is opened, and a character input mode is entered, a character input display routine shown in FIG. 4 is executed. In addition, immediately after starting the document editing device, the fifth
As shown in Figure (A), no characters are displayed on the LCD panel 3, and the display on the right end of the LCD panel 3 to indicate the print color is a "mouth" that indicates the print color "black". On the right side of
It is now marked with .

First, wait until some key is pressed from the keyboard 2 (step 100), and if there is any key pressed, it is determined whether or not it is a color change instruction using the print color designation key 24 (step 110). If the key entered via the keyboard input circuit 14 is not the print color designation key 24, then a determination is made as to whether or not the character string is confirmed (step 120). This document editing device converts what is input in kana characters into kanji, and after determining the desired character string after 1q is stored in the RAM 13 as text, the characters before being determined are displayed as inverted characters on the liquid crystal display. Panel 3
will be displayed. If a new character is input while the character string remains unconfirmed, one character is added to the unconfirmed character string, this is highlighted, written to the line memory 15, and displayed on the liquid crystal panel 3 (No. Figure 5 (B)).

On the other hand, if the character string is confirmed by pressing the confirm key, etc., processing is performed to display the confirmed characters with shading corresponding to the specified color (step 140).
. If the print color designation of the confirmed character is black, it will be displayed as is without being hung (see FIG. 5(C)). After the 91U process of steps 130 to 140 explained above,
rNEXTJ can be handled, and this routine ends immediately.

Next, the case where the print color designation key 24 is pressed will be explained. If the key input is accepted (step 100) and it is the print color designation key 24, it is determined that the color has been changed (step 110), and the processes from step 150 onwards are performed. That is, insert the color specification control code into the text (change it if it has already been specified) (step 1).
50), the print color display on the right end of the liquid crystal panel 3 is changed (step 160).

Each time the print color specification key 24 is pressed, the print color is specified.
Since the color changes in the order of "black" → "red" → "blue" → "green" → "black," the user can specify the desired print color by pressing this key 24 as appropriate. The "." indicating the print color sequentially moves between patterns 31 to 34 each time the key 24 is pressed once. For example, when the print color designation key 24 is pressed once from a state where the print color is black, the display "Φ"
moves between the printed pattern "eye" and the word "red". This situation is shown in FIG. 5 (D>).

When the input character is unconfirmed, the character is displayed in reverse (steps 120, 130>), although there is no particular difference from the case where the printing color is "black" (see Figure 5 (E)).
, once confirmed, the shading in the case of "red" is displayed together with the pattern I[J (steps 120, 140>). This state is shown in FIG. Since the shading corresponding to the printing color of the characters is displayed together with the pattern, it is possible to easily know the printing color by the color printer 4 while using the monochrome display liquid crystal panel 3. Note that if the text has already been inputted, When changing the printing color of a character string, the cursor key 26 is used to specify a range, and the printing color specification key 24 is used to change the printing color.

Therefore, according to the document editing device of this embodiment, it is possible to clearly display the printed color of characters using the thin monochrome liquid crystal panel 3, and while the multicolor printing machine rll is fully extended, it is possible to You can also fully satisfy your sexuality. Furthermore, since the document editing device of this embodiment displays the printed color on the monochrome liquid crystal panel 3, the display means can be made larger, and the angle can be changed freely (tilt panel).
Coupled with the adoption of , it becomes easier to visually check documents, and the usability of inputting and editing documents can be greatly improved.

In this embodiment, the pattern of the shading corresponding to the printing color was determined in advance and was printed on the right end of the panel 3.
The configuration may be such that it can be defined by the user, and the shaded pattern and the corresponding print color may be displayed on the liquid crystal panel 3. Furthermore, in the embodiment described above,
Although only character input was handled, it is easy to handle figures input in character units (so-called semi-graphics), specifying a print color for each figure, and displaying it on the liquid crystal panel 3 along with the mesh I) G tab pattern. It may also be a configuration.

Although a liquid crystal panel is used in the embodiment as a monochrome display means, other means such as an L panel or a plasma display may be used.

Although one embodiment of the present invention has been described above, the present invention is not limited to this embodiment in any way. For example, the present invention may be configured in such a manner that a printing device (color printer) is separated from a document editing device, or the printing color can be changed. It goes without saying that the present invention can be implemented in various ways without departing from the spirit of the present invention, such as a configuration with multiple colors, for example, seven colors.

Effects of the Invention As detailed above, the document editing device of the present invention has an extremely excellent effect of being able to clearly display the printed colors of characters forming a document using a monochrome display means. Therefore, the display section can be easily increased in size, and it is also easy to achieve both multicolor printing function and portability.
