Next, the operation of the computer system 1 configured as described above will be described. FIG. 3 is a flowchart showing a screen display process executed by the computer system 1.

In the screen display process of FIG. 3, first, in step S1, the CPU 2 reads the screen data to be processed from the screen data stored in the storage device 4.
Here, the screen data is data of a screen to be processed as one screen regardless of whether or not the screen can be displayed on the display screen of the display device 8.
(Joint Picture Expert Group), GIF (Graphics I
characters stored in various document files such as still images and various moving images, text files, and the like, or HT including these.
A document stored in the ML (HyperText Mark-up Language) format or the like can be arbitrarily configured.

In the following step S2, the CPU 2 generates display data of a virtual screen based on the screen data obtained in step S1. The virtual screen is a screen having a size larger than an area that can be displayed on the display screen, and the display screen is scrolled by moving the display area in the virtual screen.

Then, the CPU 2 sets a display area to be displayed first in the virtual screen (step S3), and displays the screen in the set display area on the display screen of the display device 8 (step S4). The position of the display area set in step S3 may be a position preset in the computer system 1 in advance, or may be a position specified by an instruction input from the input device 6.

In step S5, the CPU 2 shifts to a standby state for pressurizing the pressure sensor 73 of the pointing device 7. Here, when the pressure sensor 73 detects the pressing operation (Step S5; Yes), the CPU 2
The process proceeds to step S6 to determine whether or not the click buttons 71 and 72 are pressed. Here, click button 7
If there is a pressing operation of 1, 72 (step S6; Ye
s) Then, the process proceeds to step S7, and the moving direction of the display area set in step S3 is set to the upward direction in the display screen. If there is no pressing operation of the click buttons 71 and 72 (Step S6; No), the process proceeds to Step S8, and the moving direction of the display area is set to the lower direction in the display screen.

In step S5, if there is no pressing operation (step S5; No), the CPU 2 continues the standby state for pressing the pressure sensor 73 of the pointing device 7 again.

FIG. 4 is a view showing an example of a screen processed by the screen display processing shown in FIG.
1 and (b) shows a display area 8 displayed on the display screen.
2 is shown.

As shown in FIG. 4A, the virtual screen 81
Is a screen having a size exceeding the display area 82 that can be displayed on the actual display screen of the display device 8. This virtual screen 81
, A coordinate plane including a y-axis extending downward and an x-axis extending rightward is set with the upper left corner as the origin. In the following description, the size of the virtual screen 81 in the x-axis direction is represented by X, and the size in the y-axis direction is represented by Y. Here, the coordinates of the lower right corner of the virtual screen 81 are represented by (X, Y).

Display area 82 on virtual screen 81
Is determined by the coordinates (x, y) of the upper left corner of the display area 82,
The size _{xn of the} display area 82 in the x-axis direction and the display area 8
It is determined by the size y _n of the second y-axis direction. Incidentally, x _n and y _n indicate the size of the display area 82 in advance is determined by the number of pixels or the like can be displayed on the display screen of the display device 8.

The coordinates of the four corners of the display area 82 are (x, y), (x + x _n , y), (x, y +
y _n), represented by _{(x + x n, y +} y n).

When the display area 82 on the virtual screen 81 shown in FIG. 4A is displayed on the display screen of the display device 8, the state shown in FIG. Therefore, the virtual screen 8
By moving the display area 82 on 1, an arbitrary area of the virtual screen 81 is displayed on the display screen.

Hereinafter, the display area moving process (FIG. 3; step S1) executed on the virtual screen 81 shown in FIG.
2) will be described in detail with reference to the flowchart of FIG.

[0053] In the display area moving processing shown in FIG. 5, CPU 2, as the operation amount corresponding to the detected pressure level of the pressure sensor 73 of the pointing device 7, a component x _m of the x-axis direction, the y-axis direction The component y _m is obtained (Step S21).

Then, the value of x _m obtained in step S21 is obtained.
The coordinates (x, y) indicating the position of the display area 82 up to that time are updated based on and y _m , and the coordinates indicating the new position of the display area 82 are obtained. Specifically, the value of the coordinates (x, y) is updated by the arithmetic processing represented by the following equations (1) and (2).

X = x + x _m (1) y = y + y _m (2)

Then, the CPU 2 sets a new display area 82
Is determined whether or not the position is beyond the virtual screen 81. First, in step S23, it is determined whether the value of x is a positive value. Here, if the value of x is a positive value, the process directly proceeds to step S25. If the value of x is a negative value, the left end of the display area 82 protrudes to the left from the left end of the virtual screen 81, so that the value of x is set to 0 (zero) in step S24, and the process proceeds to step S25. I do.

In step S25, it is determined whether or not the value of (x + x _n ) exceeds the value of X. Since the value of X is the size of the virtual screen 81 in the x-axis direction, _if the value of (x + x _n ) exceeds the value of X, the right end of the display area 82 extends beyond the right end of the virtual screen 81 to the right. Would.
Therefore, when the value of (x + _xn ) exceeds the value of X, the value of (X- _xn ) is set to x in step S26, and the process proceeds to step S27. Step S25
And _if the value of (x + x _n ) is smaller than the value of X,
The process moves to step S27 without performing the process of step S26.

In the step S27, it is determined whether or not the value of y is a positive value. If the value of y is a negative value, the upper end of the display area 82 goes up from the upper end of the virtual screen 81. If the value of y is a negative value, the process proceeds to step S28 and y Is set to 0 (zero) as the value of
Move to 29. If the value of y is a positive value, the process directly proceeds to step S29.

In step S29, the CPU 2 sets (y + y
It is determined whether the value of _n ) exceeds the value of Y. (Y
+ If the value of y _n) exceeds the value of Y, the display area 82
Is below the lower end of the virtual screen 81. Therefore, the value of (y + y _n) is transition to step S30 if it exceeds the value of Y, and set the value as the value of y (Y-y _n), the process proceeds to step S31. Also, if at step S29 the value of (y + y _n) is smaller than the value of Y is step S31 without performing the processing in step S30
Move to.

In step S31, steps S23 to S23
The display area 82 is set at the position where the coordinates (x, y) determined in the processing of step 30 are set to the upper left corner, the screen in the display area 82 is displayed on the display screen of the display device 8, and the processing ends.

As described above, according to the computer system 1 of the embodiment of the present invention, for a screen larger than the displayable size on the display screen of the display device 8,
By reading the screen data, a virtual screen 81 is generated, and a screen of a predetermined display area 82 on the virtual screen is displayed on the display screen of the display device 8. When the pressure sensor 73 of the pointing device 7 detects the pressurization, the CPU 2 moves the display area 82 to a position corresponding to the moving direction and the moving amount based on the pressurizing level.

For this reason, when processing a screen larger than the displayable area by the computer system 1,
The user can adjust the amount of movement of the display area according to the amount of pressurization only by executing the pressurizing operation of the pressure sensor 73, and can quickly display a desired area of the screen desired. . Therefore, the scroll operation of the computer system 1 becomes very simple and the operation can be performed more intuitively, so that the convenience can be greatly improved regardless of the user's skill level.

Although the scroll operation is performed, the present invention is not limited to this. The zoom operation of the display area 82 may be performed. That is, by using the pressure detection function of the pressure sensor 73, the display magnification of the display area 82 may be changed according to the detected pressurization level, and the display may be enlarged (zoomed in). Also,
Pressing operation of the pressure sensor 73 and click buttons 71 and 7
It is of course possible to change the display magnification of the display area 82 to reduce the display (zoom out) by combining the click operation in Step 2 with the click operation.

Further, in the first embodiment, the operation combined with the pressing operation of the pressure sensor 73 in the scrolling operation or the zooming operation is the click operation of the pointing device 7, but the present invention is not limited to this. The present invention is not limited to this, and may be configured to be combined with a key input operation of a keyboard or the like.

The pressure sensors 73a and 73b are provided at two places on the upper surface of the case 70 so as to be pressable, and can detect the presence or absence of pressurization by the user and also detect the pressurization level. When any one of the pressure sensors 73a and 73b is pressed, an operation signal corresponding to the detected amount of the pressed pressure sensor is output to the input device 6.

Next, the operation of the computer system 1 according to the second embodiment will be described. FIG. 7 is a flowchart showing a screen display process executed by the computer system 1.

Here, the screen display processing (steps S41 to S44 in FIG. 7) executed by the computer system 1 in the second embodiment is the same as that in steps S1 to S4 in FIG. 3 in the first embodiment.

Further, the display area moving process (steps S53 to S56 in FIG. 7) executed by the computer system 1 in the second embodiment is the same as that in steps S9 to S12 in FIG. 3 in the first embodiment. This is the same as the display area moving process. Therefore, here, the moving direction setting processing of the display area corresponding to steps S5 to S8 in FIG. 3 in the first embodiment will be described with reference to FIG.

First, in step S45, the CPU 2 sets the pressure sensors 73a, 73b of the pointing device 7 to
The state shifts to a standby state for pressurization of. Next, CPU2
When the pressure sensor 73a detects a pressurizing operation (step S45; Yes), the process proceeds to step S46 to determine whether or not the click buttons 71 and 72 are pressed. Here, if the click buttons 71 and 72 are pressed (step S46; Yes), the process proceeds to step S47, and the moving direction of the display area set in step S43 is set to the right in the display screen. Click buttons 71 and 72
If no is pressed (Step S46; No), the process moves to Step S48, and the moving direction of the display area is set to the upper direction on the display screen.

If the pressure sensor 73a does not detect the pressing operation in step S45 (step S45; No), the CPU 2 proceeds to step S4.
The process proceeds to 9, where the pressure sensor 73b determines whether or not there is a pressurizing operation.

Next, when the pressure sensor 73b detects a pressing operation (step S49; Yes), the CPU 2 proceeds to step S50 to determine whether or not the click buttons 71 and 72 are pressed. Here, click button 71,
If there is a press of 72 (step S50; Yes), the process moves to step S51, and the moving direction of the display area set in step S43 is set to the left direction on the display screen.

If the click buttons 71 and 72 are not pressed (step S50; No), the process proceeds to step S52, and the moving direction of the display area is set to the lower direction on the display screen. If there is no pressure operation in step S49 (step S49; No), the CPU 2
Again, the pressure sensor 73a of the pointing device 7
The standby state for pressurizing is continued.

As described above, according to the computer system 1 in the second embodiment of the present invention, the display device 8
For a screen larger than the size that can be displayed on the display screen, a screen data is read to generate a virtual screen 81, and a screen of a predetermined display area 82 on the virtual screen is displayed on the display screen of the display device 8. . When the pressure sensors 73a and 73b of the pointing device 7 and the click buttons 71 and 72 are operated,
The CPU 2 moves the display area 82 to a position corresponding to the movement direction and the movement amount based on the pressure level.

For this reason, when processing a screen larger than the displayable area by the computer system 1,
Not only can the operation of pressing the pressure sensors 73a and 73b be used to adjust the amount of movement of the display area according to the amount of pressure applied by the user. Regardless, a desired area can be displayed quickly. In particular, the scroll operation in the vertical direction can be performed only by the pressing operation of the pressure sensors 73a and 73b. Therefore, the scroll operation of the computer system 1 becomes very simple and the operation can be performed more intuitively, so that the convenience can be greatly improved regardless of the user's skill level.
