Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a small 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 not 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.

<Problems 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. .
Conventionally, a method was used to automatically return to the original display after a certain period of time had passed after pressing the confirmation key, but with this method, the time required to confirm the string is not constant, so the confirmation does not finish. This may cause inconveniences such as the display switching during the process, or having to wait until the confirmation is complete before the display switches. 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 to designate a second character string of a predetermined number of digits on the right, top, or bottom, and when this designation key is pressed, replace the second character string with the first character string. and a display means for displaying the first character string when the specified key is returned.

<Embodiment> FIG. 1 shows the basic configuration of a Japanese word processor of this embodiment. The input device K consists of a key group K1 for character string input and four keys: left key a, right key b, up key c, and down key d.
2. The display device D is a liquid crystal display device with a small number of display digits, for example, 8 digits. sentence memory
BMR stores character strings input through input device K. The display buffer DBF has text memory
8 of the character strings registered in BMR for display device D
The character string corresponding to the displayed digit is extracted. The character string extracted into this display buffer DBF is displayed on the display device D. The output device P is, for example, a thermal transfer printer that prints input text.
The central processing unit CPU controls the display device D, text memory BMR, display buffer DBF, and output device P according to input information from the input device K.

Now, the character string shown in Figure 2 is stored in the text memory.
The cursor is located in block P, which is registered in BMR and consists of an 8-digit character string, and the display buffer is
Assume that the DBF contains the contents of block P, and the display device D displays the contents of block P. In this state, for example, if the left key a of the input device K is pressed, 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 L are stored in the text memory BMR.
The 8-digit character string of this block L is extracted from the BMR and set in the display buffer DBF, and is displayed on the display device D in place of the contents of the block P currently displayed. While the left key a is held down, the contents of block L are displayed on display device D. When the left key a is released after checking the contents of block L, the contents of block P are set in the display buffer DBF again by the return of the left key a, and the display device D returns to the original display of block P. Return to

Figure 3 shows how the display on display device D changes by operating keys a, b, c, and d, and the text memory
When the contents of block P of BMR are displayed, press the up key c to display block 8 of block U on the upper side of Figure 2 of block P of text memory BMR.
A character string of digits will be displayed. When you press the down key d, the 8-digit character string of block D located below block P will be displayed. When you press the right key b, the 8-digit character string of block R located on the right side of block P will be displayed. The string will be displayed.

On the other hand, the content currently displayed on the display device D is block 8 of block P' of the text memory BMR shown in FIG.
Since the first character of this block P' is the 6th digit from the left in the figure of text memory BMR, the 8-digit character string of block L' on the left side of block P' is the last 3 digit character string. The digits are the same as the first three digits of block P'. Therefore, when the left key a is 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 display device D 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 the text memory BMR.

<Effects> 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 confirmation is completed. Since the display returns to the original display when the key 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.
