Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides an underline control method in a text input device, particularly in a text input device such as a Japanese language input device, by providing an underline display key and an underline deletion key. Alternatively, the present invention relates to an underline control method in a text input device configured to set an erase mode so that an underline can be displayed and/or erased for each operation by operating a cursor movement key.

In a text input device such as a Japanese input device, for example, by inputting the word "Hatsumei" using the kana key and then operating the Kanji conversion key, the display changes from "Hatsumei" to "Invention". will be converted to . By using such a conversion operation, even if there is no surprise mark "!" key on the keyboard, you can register the word "odoroki" and use it under the specified mode. By operating the above-mentioned Kanji conversion key, the display on the display will be converted from "Odoroki" to "!".

Conventionally, in the above-mentioned text input devices, even when inputting an underline, the above conversion is used to input, for example, "kasen" and then the kanji conversion key is operated to display the underline. It was. However, the frequency of underline input is extremely high, and it becomes extremely troublesome to input the above-mentioned "kasen" one by one. In particular, if you try to display or delete an underline on more than one line of the display,
The above-mentioned difficulties become extremely obvious.

In order to solve this problem, it has been considered to provide an underline adding key and an underline erasing key. The operation mode is such that the underline is actually added or deleted by the next predetermined key operation, which becomes surprisingly complicated if, for example, the above-mentioned range is specified incorrectly.

The present invention aims to solve the above-mentioned problem by operating a key to move a cursor, and the underline control method in the text input device of the present invention includes: a keyboard, a display, and an image displayed on the display. It is provided with at least a display memory for storing a pattern code, and an X-axis cursor coordinate register and a Y-axis cursor coordinate register for indicating the coordinate position of the cursor displayed on the display, and the cursor coordinate register indicates the coordinate position of the cursor displayed on the display. In a text input device that converts kana characters into kanji characters and displays them on the display, at least a cursor movement key, an underline display key, and an underline deletion key are provided on the keyboard to move the cursor in up, down, left and right directions, respectively. and an X-axis direction movement step circuit unit that advances the contents of the X-axis direction cursor coordinate register by ±1 step by operating the cursor movement key; A Y-axis direction movement step circuit unit that advances the contents of the axial cursor coordinate register by ±1 step, an underline display storage unit that is set by operating the underline display key, and the underline deletion key. an underline erasure memory unit that is set by the operation of an underline generation/erase section that sets or resets an underline code on the display memory to erase the underline displayed on the display; and the underline display key or the underline erase key. Under the mode setting, operate the cursor movement key above to position the cursor at the beginning position where the underline is to be displayed or erased, and then move one step in the left/right direction based on one operation of the cursor movement key. Every step and/or every step in the vertical direction, the underline generation/erase section receives the contents of the cursor coordinate register after each step and changes the cursor coordinate position from the cursor coordinate position before the operation of the cursor movement key to the position after the operation. The underline code is set or reset in accordance with the character display device located between the cursor coordinate position and the cursor coordinate position. This will be explained below with reference to the drawings.

The figure shows the configuration of an embodiment of the present invention.

In the figure, 1 represents the main unit, 2 the display, and 3 the keyboard. Also, 4 is a character key, 5
-1 to 5-4 are cursor movement keys, and by operating the respective keys, the cursor displayed on the display can be moved in any direction (up, down, left, or right), and 6 is an under key. 9 is a key for line display; 7 is an underline deletion key; 8 is a keyboard control unit that determines key operations on the keyboard 3 and activates various operations; 9
10 is a display control unit that controls the display on the display 2; 10 is a display memory in which a code corresponding to the display pattern is set in a location corresponding to the display on the display 2; 11X, 11Y 12 is a cursor coordinate register that indicates the coordinate position on the display 2 where the cursor is displayed, and 12 is an X-axis direction movement step circuit that increments the contents of the cursor coordinate register by ±1. , 13 is a Y-axis direction movement step circuit unit which steps the contents of the cursor coordinate register by ±α;
14 is an underline display storage section, 15 is an underline erasure storage section, 16 is an underline generation/erasure section, and 17 to 21 are gates, respectively.

For normal character input, the values of the cursor coordinate registers 11X and 11Y are, for example, a certain value (X ₀ ,
For example, if the character "ha" is input in this state, the character "ha" will correspond to the coordinate position specified by the values of the registers 11X _and 11Y on the display memory 10. A code is set, and the character "C" is displayed at the corresponding position on the display 2 in the form of a character pattern. Then, the values of the registers 11X and 11Y are incremented by +1 by the X-axis direction movement step circuit section 12, and the values of the registers 11X and _11Y are increased by
1), Y ₀ }, and the cursor is moved one step to the right on the display 2. Also, one line on Display 2 is assumed to display 40 characters,
For example, the values of the registers 11X and 11Y are (40,
When the character "C" is input in the state where the character "C" is inputted, the values of the registers 11X _and 11Y are changed to {0, (Y ₀ + 1)}.

To move the cursor to any desired position, press the cursor movement keys 5-1 to 5-.
4. That is,
For example, under the state where the values of the cursor coordinate registers 11X and 11Y indicate (X ₀ , Y ₀ ), (i)
When key 5-1 is operated, registers 11X and 11Y
The value of is generally {(X ₀ + 1), Y ₀ }, (ii) when key 5-2 is operated, generally it is {X ₀ , (Y ₀ -1)}, and (iii) when key 5-3 is operated, Generally {(X ₀ −
1), Y ₀ }, and (iv) when the key 5-4 is operated, it generally becomes {X ₀ , (Y ₀ +1)}.

Although not shown, it goes without saying that the conversion function described at the beginning of this specification is provided in the main unit 1. For example, when the display "Hatsumei" is converted to the display "Invention", the display 2 The cursor display will be shifted to the left by two characters.

In the case of the present invention, the underline can be easily displayed using the cursor movement keys 5-1 to 5-4.

That is, in the present invention, the illustrated underline display storage section 14 is set by operating the underline display key 6, and the illustrated underline display storage section 14 is set by operating the underline deletion key 7. section 15 is set. Of course, the storage section 14 is reset when the key 6 is operated while the storage section 14 is set, and when the key 7 is operated. Also, when key 7 is operated with memory section 15 set, and when key 6 is operated.
, the storage section 15 is reset.

When each storage section 14 or 15 is set, a corresponding mode, ie, an underline display mode or an underline erase mode, is set. At these times, the underline generation/erasing unit 16 registers the cursor coordinate registers 11X, 11Y.
is input through the gate 20, and the coordinates (X ₁ , Y ₁ ) before operating any one of the cursor movement keys 5-1 to 5-4 and the coordinates (X ₂ , Y ₂ ), the difference between the two, that is, X ₂ −
Examine X ₁ and Y ₂ −Y ₁ . Then, the underline generation/erasing section 16 outputs the above-mentioned X ₂ −X ₁ and Y ₂ − through the gate 21 in the underline display mode.
An underline code is set at a coordinate position on the display memory 10 located between Y1 and _Y1 . Also, in underline erase mode, gate 2
1, the underline code at the coordinate position on the display memory 10 located between X ₂ -X ₁ and Y ₂ -Y ₁ is erased. That is, on the display 2, underline display or erasure is performed.

In other words, if the cursor is currently in the underline display mode and the cursor is at position a in the figure, and the cursor movement key 5-1 is operated in this state, an underline will be displayed at position a and the cursor will be at position b. will be moved. In addition, under the underline display mode, the cursor display is at position c in the figure, and when the cursor movement key 5-4 is operated in this state,
An underline is displayed from the position to the position immediately before d in the figure. Of course, under the underline erasing mode, the underline display displayed on the display 2 is erased, which is the same as above. Note that in the underline generation/erase mode, the cursor movement key 5-2 or 5-4
is operated, the cursor coordinate register 11
The values of X and 11Y are determined by the Y-axis direction movement step circuit section
It can be considered that the step is incremented by ±1 step by ±40 steps. During this time, it may be considered that the underline generation/erasing section 16 writes an underline code or an erasure code onto the display memory 10.

As explained above, according to the present invention, after creating an underline generation/erase mode, by simply moving the cursor up, down, left, or right using the cursor movement keys, each operation It becomes possible to perform desired underline display or erasure.
