In Utility Model Application No. 61-94891, the icon area is displayed where there is the least amount of screen display information when necessary, but consideration is given to the distance the mouse cursor must move to select an icon. It has not been.

[Problem to be solved by the invention]

In the prior art, for example, when a window is opened to perform some processing, the display position of the window is opened regardless of the position where the mouse cursor was displayed before the window was opened. Therefore, in order for the mouse cursor to perform processing within the window, the mouse cursor must be moved to the window position each time.

Utility Model Application Nos. 61 to 94891, which display the icon area where there is the least amount of screen information, do not take into account the position of the mouse cursor being operated on the editing screen, and do not take into account the position of the mouse cursor while editing , there was a problem with operability because the user had to move to the position of the icon displayed at the new position each time.

[Means to solve the problem]

The purpose of - is to provide a register that stores the starting position of the mouse cursor in the window when the window is opened, and when the window is opened, the mouse cursor is This is achieved by automatically and instantly allowing the cursor to be moved to the starting position of the window.

(↑J1 When the window opens, the mouse cursor will be instantly moved to the starting point in the window, no matter where it is on the editing screen, and the mouse cursor will be moved to the starting point in the window as before.) There is no need to move the screen over a long distance, and the operability in screen editing can be improved.

〔Example〕

Examples of the present invention will be described below.

FIG. 2 is a perspective view showing the general external configuration of a Japanese word processor using an embodiment of the present invention.

In FIG. 2, 200 is a main body, 108 is a display device, 107 is a key input device, and 100 is a mouse device. The main body 200 is a processing device that processes signals from the key input device 107 and the mouse device 100 which is a pointing device, and the display device 108 displays the status of a created document, a menu, a cursor, etc. Here, the cursor is used to indicate a position where input is currently possible, or to designate an area such as an icon.

The position of the cursor can be specified by pressing the scroll key on the keypad device 107 or by pressing the mouse device 100.
This is done by operating and moving the key 1-. The mouse device tooL is provided with a switch 102, which is used to set or delete a target area specified by the cursor.

FIG. 1 is a block diagram showing an overview of processing related to a mouse device according to the present invention.

The data processing section 103 and the cursor display processing section 109 are internal to the control device within the main body 200. When the data processing unit 103 requests position information from the mouse device 10013, it sends a data request 1-signal A. The mouse device 100 has a control circuit 101 inside thereof, which converts the position information of the movement of the mouse device 100 and the on/off information of the switch 102 housed in the same device into a series of data format. Arrange. Mouse device 10
When 0 receives the data request signal A, it sends the data arranged as described above serially or in parallel (j''
-J- as the mouse data signal B in the data processing unit 1
Send to 03. The data processing unit 103 calculates the movement amount and absolute position of the mouse based on the received mouse position information,
These data are stored in the mouse position data memory 106. The data processing unit 103 also operates a window data memory 10 that stores information for window display.
A window is displayed on the display screen of the CRT 108 using the data from 4. Within the window data memory 104 is a starting point data register 105 that stores the starting point of the mouse cursor when a window is opened. The cursor display control unit 109 calculates an address on the display screen from the mouse position obtained from the mouse position data memory +06, and stores the result in the cursor position data memory 110. The cursor will be displayed on the display screen according to the value of the cursor position data memory 110. Note that the above processing is generally performed by a logic operation element such as a GCPU.

FIG. 3(a) is an example of the screen display of a conventional multi-window display word processor, where 302 is a double-sided editing area;
01 is an icon area, and 303 is a mouse cursor.

When creating a document, various types of processing are performed in the screen editing area 30.
It is done in 2. For example, if it becomes necessary to select an icon and perform window processing while the mouse cursor H3O3 is being processed in the screen editing area 302, in the conventional example, the mouse device 100 moves the mouse cursor 303 onto the icon area 301, and the target After selecting an icon, the mouse cursor 30; 3 must be moved to the position of the opened window using the mouse device 100 to perform processing within the window.

Therefore, when specifying such an icon, there is a problem in that the mouse cursor 303 must be moved significantly between the screen editing area 302 where the window is opened and the icon area 301.

FIG. 3(B) shows a display screen of the display device 108 in the present invention, and is a diagram showing a state where a window is opened on the display screen I- of FIG. 3(B).

On the display screen in (B), when the need for window processing arises due to selection of an icon during data input from the key input device 107 or mouse device 100, the operator specifies the icon to be processed using the mouse device 100. death,
Open window A304. The window A304 is displayed on the screen of the display device 108 based on the data of the window A304 that the data processing unit 103 reads from the window data memory 105. At this time, mouse cursor 3
03 is located at A in the icon area 301, and when the window A 304 is opened as described above, the data processing unit 103 reads the data corresponding to the window A 304 from the starting point data register 105 in the window data memory 1.04, and moves the cursor The data is written in the position data memory 110, and the mouse cursor 303 is displayed at the starting point B of the window 1-A 304. Therefore, the subsequent processing can be carried out smoothly by simply moving the mouse cursor 303 within the windows A403.

Furthermore, even if window B505 is opened by performing processing in window A304, the mouse cursor 303 can be moved to The image is instantly moved and displayed to the starting point C set in .

Therefore, for window processing as in the past, the operator
There is no need to move the mouse device 100 over a long distance on the desktop each time, and the operability in document editing is improved.

FIG. 4 shows these processes in flowchart 1.

[Effects of the Invention] According to the second invention, when a window is opened, no matter where the mouse cursor is on the editing screen, the mouse cursor is instantly moved to the starting point in the window, which eliminates the need for conventional methods. There is no need to move the mouse cursor a long distance on the desktop each time window processing is performed, and this has the effect of significantly improving the operability in screen editing.
