In such a configuration, the keyboard 20 as described above
A character string is input by a predetermined operation.

The main operations and associated operations of the input/output device equipped with the display device according to the present invention will be disclosed below with reference to the keyboard of FIG. 3.

To start document creation, set the range in which a character string should be entered in one line, that is, set the print range by pressing the print range setting key 38, then input the print range using the desired number keys, and then start printing again. By pressing the range setting key 38, the printing range can be registered.

Regarding the setting and registration of the printing range, please refer to January 1989.
This is detailed in the specification of Japanese Patent Application No. 59-5450 filed on May 13th.

For alphanumeric or katakana input, select the respective selection key 24.
After pressing down to enter each mode, input is performed using the character keys 22, and the contents are displayed on the display 21 to perform document creation, printing, storage, updating, etc. If necessary, by switching the character type selection key 41, for example, if the number of dots for a full-width character in the horizontal direction is set to 24,
Half-width with half 12 dots and double 48 dots
You can also select either double angle. Note that half-width characters are valid only for some alphanumeric characters and special symbols.

To enter hiragana, press the hiragana selection key 24 (or the romanization selection key 36), then press the character key 2.
Press 2. The hiragana characters input in this way are displayed in reverse video on the display 21. If this display is correct and does not require conversion, the no-conversion key 26 is pressed to confirm the normal display. To input a kanji, enter the reading of the desired kanji in the hiragana mode or romaji mode, and then press the conversion key 27.

Along with this, candidate kanji or compound words are displayed on the display 21, so you can select the desired kanji or compound word by using the corresponding number keys.If there are many candidate letters, press the conversion key 27 again. If you go too far and want to return to the previous candidate character group, you can use the previous candidate key 28 to return to the previous display. This kanji conversion converts to normal display.

FIG. 5 shows an example of a display device according to the present invention. A display device (display) 21 includes a data display section 211 and a layout display section 212, as shown.

The data display unit 211 displays one full-width character in one frame shown in the figure. Therefore, in the case of half-width characters, two characters are displayed in one frame, and in the case of double-width characters, one character is displayed in two frames. Note that a line head mark (-) is displayed at the beginning of a line, and a line-end mark () is displayed at the end of a line (not shown).

The layout display section 212 is approximately one part of the data display section 211.
It has a width of about 1/3 to 1/4 and a length of about 1/2 of the entire display. When the display 21 is a liquid crystal display, this layout display section 212 can be advantageously implemented using a part of the display.

Further, other display devices such as LEDs that can display on/off may also be used.

In this embodiment, this layout display section 212 is
Absolute printing range LA and RA, printing range LP and RP
, cursor position C1 and tab position T are displayed, 1
The display CH of the input character in the print line is displayed. here,
The absolute print ranges LA and RA indicate the left and right limits that can be input in one print line in the input/output device. The print ranges LP and RP indicate the left and right sides of the print range currently set and registered by the print range setting key 38 on the keyboard shown in FIG.

The cursor position C indicates the position of the cursor in the currently displayed line in relation to the character display CH, which will be described later. In the example in Figure 5, the third character “
Since the cursor 213 exists under "U", it is positioned at the third character display CH in the layout display section 211. Although tab position T does not appear in the data display section, it is similarly shown that it is located at the fifth position corresponding to the character "o".

The character display CH has a length proportional to the width of the character, that is, based on a full-width character, a half-width character is displayed with half the length, and a double-width character is displayed with twice the length. Therefore, by checking the layout display section 212, you can see at a glance whether or not the data is displayed in the data display section 211, where the cursor is in the line, and what is the relationship with the tab setting position. Document production with input/output devices having displays shorter than lines can be advantageously implemented.

FIG. 6 shows an example of the display state of the character display CH in the data display section 211 and the layout display section 212 when different character types are displayed in this embodiment. In the figure, the symbol ■ for the layout display section 212
The corresponding portion is displayed in full-width because the characters rAJ and rBJ in the data display section 211 are full-width characters. Since the characters "C" and rDJ at the next positions are each half-width characters, the zero-order position, which is displayed as a half-width character corresponding to the symbol ■ in the layout display section 212, is a blank (space), so the layout display section is also blank like the symbol ■. The next character "E" is a full-width character, but the next character rFJ is a double-width character, so the width is doubled, so the layout display in the layout display section 212 also corresponds to this, like the symbol ■. will be displayed at double angle. Note that the cursor 213 is currently in double-width mode, so the double-width character "
It straddles the frame for two characters after "F". Therefore, the cursor C is also displayed on the layout display section 213.

Print range setting and associated operation of the display device will be disclosed below with reference to the flowchart in FIG. 7.

When this flow starts, as in step 101, the absolute print range and the current print range are displayed on the layout display section 212 of the display device.

Next, in step 102, it is determined whether key personnel were available. If this determination is No, the process returns to before step 102 and waits. If this determination is YES, in step 103, it is determined whether or not the input key is pressed manually with respect to printing range setting/registration, that is, with the printing range setting key 38 in FIG. 3 and any number key. is judged. If this determination is YES, the storage contents of the print range storage area 621 of the memory 62 are changed as in step 104, and then the storage contents of the layout storage area 622 of the memory 62 are changed as in step 105. Accordingly, the printing range display in the layout display section 212 is changed, and the process returns to before step 102.

On the other hand, if the determination in step 103 is NO, other corresponding processing is performed as in step 106, and the process returns to before step 102 to wait for the next key input.

FIG. 8 is a flowchart showing the character type display operation. When this flow starts, it is determined in step 110 whether or not there is key human power. This judgment is N
If o, wait until key personnel are available. If this determination is YES, it is determined in step 111 whether or not the human key is a character key. If this determination is No, other corresponding processing such as step 112 is performed.

If the determination in step 111 is YES, step 11
3, it is determined whether the character type is full-width. If this determination is YES, a full-width layout is displayed at the position on the layout display section 212 corresponding to the position specified by the cursor 213 of the data display section 211, as in step 114.

On the other hand, if this determination is No, it is determined in step 115 whether the character type is "half-width" or "double-width". Depending on this determination, either half-width layout display as in step 116 or double-width layout display as in step 117 is performed. After each layout display section is displayed, the user waits for the next key human effort.

Effects of the Invention According to the display device of the input/output device according to the present invention, although the data display section is shorter than one print line, a layout display of one character line for the whole town is performed, so the trouble in document creation is saved. , the usability of an input/output device equipped with this device is improved.
