[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an input control device in a word processor, personal computer or the like.

[0002]

2. Description of the Related Art Conventionally, in a document processing device such as a word processor, a cursor on a display screen can be switched at once by a display switching function such as the beginning of a sentence, the end of a sentence, the beginning of a line, the end of a line, the next page, and the previous page. In the case of alternately designating two areas greatly separated in distance and repeatedly inputting data in each area, the up, down, left, and right cursor keys are operated to input data.

[0003]

However, in such a case, the operation of moving the cursor over a wide range has to be repeated many times, which imposes a heavy burden on the user. An object of the present invention is to make it possible to efficiently specify data input areas or the like that are widely separated from each other in an alternating manner, without moving the cursor or the like over a wide range.

[0004]

Means for Solving the Problems The means of the first invention (the invention according to claim (1)) is as follows. (1) The first and second designation means designate any position on the display screen. (2) The selecting means selects which of the first and second specifying means is valid. (3) The input control means sets the position on the display screen currently designated by the designation means selected by the selection means as an input target, and the display screen currently designated by the other designation means. Set the position above to be excluded from input. Means of the second invention (the invention according to claim (2)) is as follows. (1) The first and second cursor position storage means store the cursor position on the display screen. (2) In response to the cursor movement command, the cursor movement means rewrites the contents of the first cursor position storage means and moves the cursor on the display screen. (3) The switching means interchanges the contents of the first and second cursor position storage means when a cursor switching command is input. The main cursor is displayed on the display screen based on the content of the first cursor position storage means, and the auxiliary cursor is displayed on the display screen based on the content of the second cursor position storage means. A display control means for displaying the main cursor and the auxiliary cursor in a distinguishable manner may be provided.

[0005]

The operation of the means of the first invention is as follows. Now, when the selection means selects one of the first and second designation means to be valid, the input control means causes the display screen currently designated by the designation means selected by the selection means. The upper position is set as the input target, and the position on the display screen currently designated by the other designating unit is set as the non-input target. The operation of the means of the second invention is as follows. In response to the cursor movement command, the cursor movement means rewrites the contents of the first cursor position storage means and moves the cursor on the display screen. When the cursor switching command is input, the switching means interchanges the contents of the first and second cursor position storage means. Therefore, in the case of repeatedly specifying data input areas, etc. that are widely separated in distance,
It is possible to specify efficiently without moving the cursor or the like in a wide range.

(First Embodiment) A first embodiment will be described below with reference to FIGS. FIG. 1 is a block diagram showing a document processing device such as a word processor. A CPU 1 is a central processing unit that controls the overall operation of this document processing apparatus according to various programs stored in a ROM 2 or the like. As its peripheral devices, the CPU 1 has a keyboard 3 and a CR.
The T display device 4, the disk device 5, and the printing unit 6 are connected via the keyboard control unit 7, the CRT control unit 8, the external storage control unit 9, and the print control unit 10, and control their input / output operations. That is, the keyboard 3 has up / down / left / right cursor keys for moving the cursor displayed on the text screen of the CRT display device 4, character keys for inputting document data, various function command keys, etc. The document data input from the keyboard 3 via the keyboard control unit 7 is taken in, given to the CRT control unit 8 to be displayed and output at the cursor position on the text screen, and RA
It is stored in the document data storage area 11-1 which constitutes M11. When a document save command is input from the keyboard 3, the document data in the document data storage area 11-1 is read and given to the external storage control unit 9 to be registered in the disk device 5, and the document print command is issued from the keyboard 3. When is input, the document data in the document data storage area 11-1 is given to the print control unit 10 and is printed out by the printing unit 6.

The RAM 11 is a document data storage area 11-1.
In addition to the above, the main cursor pointer storage area 11-2, the auxiliary cursor pointer storage area 11-3, and the like are provided. In this embodiment, two types of cursors are provided. It is called an auxiliary cursor. The main cursor pointer storage area 11-2 stores various pointers for managing the main cursor position on the display screen, and the auxiliary cursor pointer storage area 11-3 stores various pointers for managing the auxiliary cursor position on the display screen. Is what
When the cursor switching key on the keyboard 3 is operated, the contents of the main cursor pointer storage area 11-2 and the contents of the auxiliary cursor pointer storage area 11-3 are exchanged with each other.

The operation of this embodiment will be described below with reference to the flow chart shown in FIG. Now, as shown in FIG. 3, in the same page, positions A, B,
It is assumed that the power supply is turned on to alternately specify C, D and E to input the line. First, the main cursor page pointer, the main cursor line pointer, and the main cursor column pointer in the main cursor pointer storage area 11-2 are respectively "0".
Is set to initialize the value, and "0" is set to the auxiliary cursor page pointer, the auxiliary cursor line pointer, and the auxiliary cursor digit pointer in the auxiliary cursor pointer storage area 11-3, respectively. Initialization processing for initializing the value is performed (step S1). Next, the main cursor pointer storage area 11
The main cursor page pointer, the main cursor line pointer, and the main cursor digit pointer within -2 are converted into display coordinates to obtain the display X coordinate and the display Y coordinate (step S2).

The main cursor pointer storage area 11
-2, the main cursor and the auxiliary cursor are displayed and output on the display screen based on the contents of the auxiliary cursor pointer storage area 11-3. Now, the main cursor pointer storage area 11-2 and the auxiliary cursor pointer storage area 11-3 are displayed. Since the respective pointer values of are respectively "0", the main cursor and the auxiliary cursor are respectively displayed at the positions of the display coordinates "0, 0" (step S3). In this state, in order to move the main cursor to the point A, the down cursor key and the right cursor key are operated. When it is detected in step S4 that the right (left) cursor key has been operated, the cursor digit pointer in the main cursor pointer storage area 11-2 is incremented by one digit (step S5). In this case, the cursor line pointer advance (lower) processing and the cursor page pointer advance (lower) processing are performed as usual in accordance with the current cursor position. When it is detected in step S6 that the up (down) cursor key has been operated, the cursor row pointer in the main cursor pointer storage area 11-2 is incremented by one digit (step S7). In this case, the cursor page pointer is moved up (lowered) as usual in accordance with the current cursor position.

When the processing for updating the various pointer values in the main cursor pointer storage area 11-2 (steps S5 and S7) is performed in accordance with the operation of the up, down, left, and right cursor keys in this way, the process returns to step S2, and these Since the display coordinates are obtained from the pointer value of and the cursor is displayed (step S3), the main cursor can be moved to the point A. In this case, the auxiliary cursor remains displayed at the initial position.

If it is assumed that the cursor switching key is operated in this state, the process proceeds to step S9, in which the contents of the main cursor pointer storage area 11-2 and the contents of the auxiliary cursor pointer storage area 11-3 are exchanged with each other. Done. That is, the values of the main cursor page pointer and the auxiliary cursor page pointer are exchanged with each other, the values of the main cursor row pointer and the auxiliary cursor row pointer are exchanged with each other, and further, the main cursor digit pointer and the auxiliary cursor digit The value with the pointer is exchanged with the value. As a result, the main cursor pointer storage area 1
The contents of 1-2 are changed to the initial position, and the contents of the auxiliary cursor pointer storage area 11-3 are changed to the A point position. Then, returning to step S2, the cursor is displayed (step S3), so that the main cursor is at the initial position,
The auxiliary cursor moves to the point A position.

Next, the up, down, left and right cursor keys are operated to move the main cursor from the initial position to the B point position. In this state, when the key for instructing the line input is operated to draw the line connecting the points A and B, it is detected in step S10 that there is another key input, and the process proceeds to step S11. , Processing according to the key input is performed. In this case, the line drawing process is performed, but when the character key is input, the character input process is performed and the input character is set at the main cursor position. And step S
Returning to step 3, when the cursor switching key is operated again, the contents of the main cursor pointer storage area 11-2 and the contents of the auxiliary cursor pointer storage area 11-3 are exchanged with each other in step S9. The position and the auxiliary cursor move to the B point position (steps S2, S
3).

In this state, after operating the cursor key to move the main cursor from the position A to the position C,
A line connecting the points A and B is drawn (step S1).
1). Here, when the cursor switching key is operated, the main cursor is moved to the B point position and the auxiliary cursor is moved to the C point position by the exchange processing in step S9. Further, by operating the cursor key to move the main cursor from the B point position to the D point position and drawing a line connecting the C point and the D point, when the cursor switching key is operated again, the main cursor moves to the C point position. The auxiliary cursor moves to the point D position. Hereinafter, the same operation is repeated. In this way, A point, B point, C point, D
When drawing a line connecting two points by alternately specifying points and E points, draw the main cursor from B point to C point, and from C point to D point.
It is not necessary to move over a wide range from the point and the point D to the point E, and it is sufficient to move from the point A to the point C, the point B to the point D, and the point C to the point E.

(Second Embodiment) A second embodiment will be described below with reference to FIGS. 4 and 5. FIG. 4 is a block diagram of the document processing apparatus in the second embodiment, which is basically the same as the first embodiment, but in the second embodiment, the main cursor and the auxiliary cursor can be distinguished from each other. The display form is different, and the cursor display data memory 13 stores the main cursor display data (bar cursor) and the auxiliary cursor display data (rectangular cursor), and the main cursor is displayed blinking and the auxiliary cursor is displayed lit.

In this embodiment, the case where the address book file as shown in FIG. 5 is input and created is used. The "name" column is the left end of the display screen, and the "phone number" column is the display screen. It is located at the right end of, and is greatly separated by distance. In such an address book file, "name" and "phone number"
When alternately specifying the fields of and inputting the name and the telephone number corresponding to it, in the past, after entering the name, the cursor must be moved to a wide range in order to move the cursor to the corresponding telephone number field. . In such a case, in the present embodiment, when the auxiliary cursor is set in the telephone number field and the main cursor is moved to input a name and then the cursor switching key is operated, the same as in the first embodiment described above. The contents of the main cursor pointer storage area 11-2 and the auxiliary cursor pointer storage area 1
The contents of 1-3 are interchanged with each other. Therefore, the main cursor moves to the telephone number field and the auxiliary cursor moves to the name field. When the cursor switching key is operated again after inputting the telephone number, the main cursor moves to the corresponding name field and the auxiliary cursor moves to the telephone number field. After entering the name and phone number of one person in this way, when entering the name and phone number of the next person, operate the down cursor key to move the main cursor to the name field of the next person. Let Hereinafter, the same operation is repeated.

In the case of inputting data by alternately designating the data input areas which are widely separated from each other in this way, the first
Similar to the embodiment, it is not necessary to move the cursor over a wide range, and it is sufficient to operate the cursor switching key.

In the above embodiment, one main cursor and one auxiliary cursor are provided. However, for example, two or more auxiliary cursors are provided, and one of the auxiliary cursors is designated according to a predetermined order. The positions of the cursor and the main cursor may be exchanged with each other, and in addition, the numbers of the main cursor and the auxiliary cursor are arbitrary.
Further, in the icon menu display area, for example, it can be applied to a case where the icon displayed at the left end and the icon displayed at the right end of the display area are alternately designated. That is, in a state where one cursor is displayed on the icon on the left end and the other cursor is displayed on the icon on the right end, the icon on the right end or the left end is activated by activating one of the cursors each time the cursor switching key is operated. May be specified alternately.
