Abstract

PURPOSE:To eliminate a standby time until a display is switched and to limit a key operation to one by displaying a character string to be recognized while a key is held depressed and returning the display to its original one when the key is released upon the completion of the recognition. CONSTITUTION:An input device K connected to the CPU of a Japanese word processor is provided with a character string input key group K1 and a key group K2 composed of a left-hand key (a), a right-hand key (b), an upper key (c) and a lower key (d). A display device D with a small number of display digits, a display buffer DBF, a sentence memory BRM and an output device P are connected to the CPU. Through the operation of the keys (a)-(d) of the key group K2 of the input device K, a character string with the prescribed number of digits, which substitutes for the character string currently displayed on the display device D, is specified. When the keys (a)-(d) are depressed, the character string is displayed and recognized. When the keys (a)-(d) are released, the display is switched to its original one, whereby the standby time until the display is switched is eliminated and one key operation switches the display.

Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a small-sized Japanese word processor equipped with a display device that displays sentences with a small number of digits.

<Prior Art> In a Japanese word processor equipped with a display device with a small number of display digits, only a small portion of the input text is displayed. Therefore, when creating or editing a text, it is necessary to check the hidden portion of the text. In this case, in order to confirm the character strings above, below, left and right of the character string being displayed, the confirmation key is pressed to temporarily switch the display.

<Problem to be solved by the invention> As mentioned above, the character string is confirmed by temporarily switching the display by pressing the confirmation key, but once the confirmation is completed, it is necessary to return to the original display. .

Previously, the method was to automatically return to the original display after a certain period of time had passed since the confirmation key was pressed.
In this method, the time required to confirm a character string is not constant, resulting in inconveniences such as the display switching before the confirmation is completed, or the user having to wait until the confirmation is finished and the display switching. Another method is to press a key other than the confirmation key when confirmation is complete, but in this case, the operation is complicated.

Means for Solving the Problems> The present invention provides a Japanese word processor equipped with a text display device with a small number of display digits. A designation key that designates a second character string of a predetermined number of digits on either the upper or lower side, and when this designation key is pressed, the second
The apparatus is characterized by comprising a display means for displaying the character string in place of the first character string, and for displaying the first character string when the designated key is returned.

<Embodiment> FIG. 1 shows the basic configuration of a Japanese word processor of this embodiment. The input device has one key per group for inputting character strings.
2 is provided in a key group consisting of four keys: hard key a, hard key b, field key C, and country key d. The display device is a liquid crystal display device with a small number of display digits, for example, 8 digits. The text memory BMR stores character strings input from the input device K. The 0 display buffer DBF stores character strings corresponding to the 8 display digits of the display device among the character strings registered in the text memory BMH. Extracted. The character string extracted to this display buffer DBF is displayed on the display device. The output device P is, for example, a thermal transfer printer that prints input text. The central processing unit CPU controls the display device, text memory BMR, display buffer DBF, and output device P in accordance with input information from the input device K.

Now, a character string as shown in Fig. 2 is registered in the text memory BMH, the cursor is located in block P consisting of an 8-digit character string, the contents of block P are in the display buffer DBF, and the display device is Assume that the contents of block P are displayed in . In this state, for example, if there is a problem key a on the input device.
When you press , a block L consisting of an 8-digit character string on the left side of the block P in the figure is specified in the text memory BMR, and the contents of this block are extracted from the text memory BMR and set in the display buffer DBF. The 8-digit character string of this block L is displayed on the display device in place of the contents of the block P currently displayed. While the prisoner key a is held down, the contents of block L are displayed on the display device. Then, when the contents of the block P have been confirmed and key a is released, the contents of block P are set in the display buffer DBF again due to the return of this key a, and the display device returns to displaying the original block P. Return to

Figure 3 shows how the display on the display device changes by operating the keys a, b, c, and d. When the contents of block P of the text memory BMR are displayed, pressing the country key The 8-digit character string of block U located on the upper side of block P in the memory BMR in FIG. When hard key b is pressed, the 8-digit character string of block R on the right side of block P is displayed.

On the other hand, if the content currently displayed on the display device is an 8-digit character string of block P' of the text memory BMR shown in FIG.
Since it is the sixth digit of R from the left in the figure, the last three digits of the eight-digit character string of block L' on the left side of block P' are the same as the first three digits of block P'. Therefore, the prisoner key a
When pressed, the contents of block L' whose last three digits are the same character string as the first three digits of block P' are displayed.

FIG. 5 shows how the display on the display device is switched by operating keys a, b, c, and d when the current display content is block P'.

The flowchart in FIG. 6 shows the above-described processing procedure when the current display content is block P of text memory BMR.

Effect> As explained above, in the present invention, in a Japanese word processor equipped with a display device with a small number of display digits, the character string to be confirmed is displayed while the key is held down, and the character string to be confirmed is displayed when the confirmation is completed and the key is pressed. Since the display returns to the original display when the button is released, there are no inconveniences such as switching the display while checking, or having to wait until the display switches, unlike in the past. Furthermore, since it is possible with a single key operation,
Easy to operate.
