Description

[Detailed description of the invention] (B1 Industrial application field The present invention relates to a cursor resizing method.

(1) Conventional technology On the ORT screen of a word processor, personal computer, etc., a cursor mark (hereinafter referred to as a cursor) is configured to display the processing position (for example, in 1982). May 20th
All about Newton Bessatsu 1 Word Processor published on the date).

In recent word processors, there are many types of characters that can be displayed (on a CRT screen): full-width, half-width, single-width, superscript, and subscript. In order to select and display any one of these cursors on a device that can display multiple cursors corresponding to each character size, multiple keys are required to select the cursor, and the device configuration I didn't like it.

Therefore, Japanese Patent Application No. 59-70465 proposes a method of cyclically changing and displaying a plurality of cursors of different sizes according to the input of a specific key.

(c) Problems to be solved by the invention 1. For example, by inputting the specific key mentioned above, the cursor will move cyclically like [full-width → half-width - double-width → superscript → subscript → full-width →...] In a device whose size is changed, if a double-width size cursor is currently displayed on the display device and an attempt is made to change it to a full-width size cursor, the above-mentioned specific key must be input twice.

B) Means for Solving the Problems The present invention has been made in view of the above problems, and includes a basic cursor having a basic size as a cursor displayed on one display device, and a plurality of cursors having different sizes from the basic cursor. and a device for cyclically changing and displaying the size of the cursor on the display device according to a predetermined order based on a cursor change instruction signal input from an input means, wherein the change instruction signal is input. and when the input from the input means immediately before inputting the change instruction signal is other than the change instruction signal, a basic cursor is displayed on the display device.

(E) Operation In this method, if a change instruction signal is input immediately after a signal other than a change instruction signal is input, a basic cursor is displayed on the display device.

N Embodiment FIG. 1 shows a block configuration of an embodiment device to which the method of the present invention is applied.

(1) is a control section consisting of, for example, a microcomputer, and the control section is connected to each of the sections described below via path (2) based on a control program stored in advance in a built-in ROM (read-only memory). control.

(3) is an input means, and the input means, for example, as shown in FIG. The cursor position change keys (5) (51, . . . , change instruction keys (6) for giving instructions to change the cursor size, etc.) are provided.

(7) is a display device consisting of, for example, OR'I', and each display area of the display device has characters, symbols, etc. stored in positions corresponding to the above-mentioned areas in the text mesori, which will be described later. Is displayed.

(8) is a cursor address storage section, and the display position of the cursor displayed on the display device (7) is stored in the storage section.

(9) is a cursor mode storage section, and the storage section 1: is size information of the cursor displayed on the display device (7).

That is, information on which size cursor to display among a full-width cursor, a half-width cursor, a superscript-size cursor, and a subscript-size cursor is stored in the display device (7).

aυ is a cursor creation unit, which creates a full-width cursor AK, a cow-angle cursor I1, . One of the superscript cursor UK and the subscript cursor DK is displayed in the display area of the display device (7) corresponding to the cursor address stored in the cursor address storage section (8).

Note that each of the above cursors is a cursor that has half the width of the full-width cursor as shown in FIG. 3 (b), and the cursor shown in FIG. The cursors UK, DK, superscript, and subscript are cursors that have the size A of the full-width cursor AK, as shown in Figure 3 (cl (dl), respectively. Figure 3 (bl (
d (dl The dotted line frame indicates the size of the full-width cursor AX.

(111) A text memory made of, for example, RAM (Random Access Memory), in which display information such as characters, symbols, etc. input through the input means (3) is stored.

α2 is a flag portion, and the flag portion (: is the information inputted to the direct spinning from the input means (3), that is, the input means (3)
Information as to whether the key pressed in is the change instruction key (6) is stored. Specifically, when the key pressed immediately before is the change instruction key (6), the flag part a
The content FLA() of 2 is 1", and when it is another key, FLAG is "0".

FIG. 4 is a flowchart showing the operation of the apparatus of this embodiment based on the above control program, and the operation of the apparatus of this embodiment will be explained below based on this flowchart.

First, in step 81, the contents of the flag section α2 are set to 1.
1# and information AK representing a full-width cursor is stored in the cursor mode storage section (9).

Next, in step S2, a key input from the input means (3) is waited, and when the key input is performed, it is determined whether the input key is a character key (4) or not in step S4.
It is determined whether it is a change instruction key (6) or another key other than these, and if it is determined that it is a single character key (4), the process proceeds to steps 85 to S7 and 814 (character input stage). After processing, the process returns to step S2, and when it is determined that the change instruction key (6) is pressed, the process processes steps 89 to 814 (cursor change stage) and returns to step S2.

If it is determined that the key is another key, the process proceeds to 88°S7.
Process S14 step (other processing stages) and
Return to step 2.

Middle Character input stage First, in step S5, the character/symbol, etc. corresponding to the character key (4) inputted from the input means (3) is inputted by the cursor address in the cursor address storage section (8) (test)-1d. Store it in the storage location in memory.

Next, in step S6, the contents of the cursor address storage section (8) are rewritten to a cursor address indicating the position where the character, symbol, etc. corresponding to the next input character key (4) is to be displayed.

In the following step S7, the contents of the flag section (121) are changed to 1.
1() #, and in step S14, the display contents of the display device (7) are changed based on the contents of the text memory αI), and at the same time, the cursor creation unit (11
displays the cursor. Note that the size of the cursor is determined based on the content CM of the cursor mode storage section (9).

In step C111 and other processing stages 88, for example, if the paper cursor position change key (6) is pressed by the input means (3), the contents in the cursor address storage section (8) are rewritten based on the manual input of the key.

Next, as in the one-character input stage, steps C287 and C191 are performed, and in step 88, in addition to the above-mentioned processing, processing such as deletion and insertion that is carried out by a normal word processor or the like can be executed.

(ill Cursor change stage First, in step 2 of 89, it is determined whether the contents of flag section 2 are 1llI# or not. If it is '1#, the process proceeds to step 812; otherwise, the process proceeds to step 8.
Proceed to step 10.

At step 810, it is determined whether the information in the cursor mode storage section (9) is information indicating a full-width cursor AK. If +1'AK", the process proceeds to step C2 at 812; otherwise, the process proceeds to step S11. Proceed to step.

In step 811, information AK indicating a full-width cursor is stored in the cursor mode storage section (9).

Further, in step 812, the information in the cursor mode storage section (9) is rewritten in the order shown by the solid line in FIG. 5, for example. That is, if the content OM of the cursor head storage section (9) immediately before reaching one step is AK, it is rewritten to HK in one step.

When steps 811 and 812 are completed, the contents of the flag section az are rewritten to 11'' in step 813, and step 814 is processed, and the process returns to step S2.

Now, the predetermined order in step 812 is as shown in FIG.
. . ”. At this time, if the change instruction key (6) is always input at step 82, the process will proceed to steps S2.83, 84.89.8.
Since the loop consisting of 12, 813, and 1914 steps is processed cyclically, the cursor displayed on the display device (7) changes regularly as described above.

Further, immediately before inputting the change instruction key (6), a key other than such a key, such as a character key (4), is input, and information other than the information AK indicating a full-width cursor is stored in the cursor mode storage section (9). ing. In other words, when the half-width, superscript, or subscript cursor is displayed on the display device (7), when the conversion instruction key (6) is input, 82.83%84.8
Steps 9, 810, 811, 813, and 814 are processed in sequence, and information AK representing a full-width cursor is stored in the cursor mode storage section (9), and a full-width cursor is displayed on the display device (7) ( (Illustrated with a broken line in FIG. 5).

1. In this embodiment, when the full-width cursor is selected as the basic cursor and the change instruction key (6) is input, other keys such as the character key (4) are input to the key manually, and the basic cursor is The basic cursor does not have to be a full-width cursor.

(G1) Effects of the Invention According to the present invention, it is possible to call up the basic cursor by manually pressing the change instruction key once.
