BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a small-sized computer, particularly suitable for portable (not stationary) computer.

[0002]

2. Description of the Related Art A conventional example will be described with reference to FIGS. FIG. 3A shows an XY direction input device (commonly called a mouse). The X-Y direction input device is connected to a stationary electronic computer by a cable, for example, and the position sensor output is input to the electronic computer. Regarding the input of the X-Y displacement amount, for example, in the case of cursor movement, when the ball 3 shown in FIG. 3B is rotated, the cursor on the display screen is displaced in proportion to the rotation amount. Actually, the X-Y direction input device 1 is placed on a flat surface in the X and Y directions.
The ball 3 is rotated so as to slide in the direction.

FIG. 4 shows a conventional small portable electronic computer. In recent years, even though they are small and portable, many have a large screen processing function, and cursor control has become necessary. In the case of the small portable computer shown in the figure, the cursor control key 6 is used to move the cursor vertically and horizontally. Of course, the screen display can display any desired portion by scrolling or the like.

[0004]

In an electronic computer having a large screen processing function, efficient work can be performed by using an XY direction input device such as a mouse for changing the position of a window or the position of a cursor. it can. In recent years, small portable electronic computers have come to have a large screen processing function as described above, and spreadsheets and the like have become possible. Therefore, in order to set or change the position of the window or change the position of the cursor, the above-mentioned XY
Although a directional input device is required, a mouse or the like is not used in a portable device, and a cursor control key provided in the computer body is used. Therefore, when executing a spreadsheet program or the like, efficient operation could not be performed. Depending on the key, it is difficult to perform an operation that fits human sensibilities (for example, when directly moving in an oblique direction). In addition, the display area of the small computer is limited, and it is difficult to display the desired screen.

[0005]

The electronic computer of the present invention is, for example, a display device 12 provided on the upper surface of a housing as shown in FIG.
And a storage element for storing display screen information in the housing, and a position sensor 15 provided in the housing. The electronic computer 7 is provided with a moving amount and a moving direction of the computer 7. By detecting a part of the display screen information stored in the storage element according to the output of the position sensor 15 according to the output of the position sensor 15 and displaying a part of the display screen information on the display device 12, The display screen scrolls as the computer 7 moves.

[0006]

According to the present invention, the display screen is scrolled as the electronic computer is moved, and a part of the display screen information is displayed on this display screen. Therefore, even an electronic computer having a small display device can be used. Can perform relatively large-scale spreadsheets.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a computer according to the present invention will be described below with reference to the drawings. FIG. 1A shows a plan view of a small-sized computer of this example and a virtual screen to be processed conceptually superimposed on each other. Only a part of the virtual screen is displayed on the screen (text, etc.) display surface. FIG. 1B is a side view of the compact electronic computer of FIG. 1A. In FIG. 1A, 8 is a virtual screen, and 9
Is a switch (a), 10 is a switch (b), 11 is a switch (c), 12 is a display surface, 13 is a cursor, and 14 is an input key. In addition, in FIG. 1B,
Reference numeral 15 is an XY direction input device showing an example of using a ball, for example. In FIG. 1A, the small computer 7 of this example
Has a predetermined size (for example, 120 × in this example) on the upper surface of the housing.
120 mm ² ) display surface (for example, liquid crystal display in this example)
Is provided so that the display area of the virtual screen 8 can be displayed as wide as possible. The virtual screen 8 refers to a screen in which the substantially maximum storage capacity of the storage element is virtually replaced, and only a part thereof is displayed on the display surface 12 based on an electrical processing method. In this example, a rewritable memory element (eg, RAM) is used as the memory element forming the virtual screen 8.
It is now assumed that the small computer 7 of this example is placed on a desk and operated. First, in order to change the area (window) of the virtual screen 8 displayed on the display surface 12, while pushing the switch (a) 9, the main body of the small computer 7 is moved in the XY directions on the tabletop of the desk. Slide it. As a result, the X-, which is partially exposed and attached to, for example, the bottom surface of the small-sized computer 7.
The ball 15 of the Y-direction input device rotates and the area (window) of the virtual screen 8 displayed on the display surface 12 changes (called scrolling).

At this time, when the small computer body is slid forward on the desk, the virtual screen 8 on the display surface 12 is moved / scrolled in the opposite direction. Further, when the small computer body is slid to the left on the desk, the virtual screen 8 on the display surface 12 moves in the opposite direction, that is, to the right and the left screen is displayed.
Make it scroll. Also at this time, the cursor 13
Should remain in the position immediately before the switch (a) 9 was pressed.

Next, to change the position of the cursor 13,
When the computer body is slid on the tabletop of the desk while pressing the switch (b) 10, the ball 15 rotates and the position of the cursor 13 on the display surface 12 changes. At this time, if the main body of the small electronic computer 7 is slid forward on the desk, the cursor 13 also moves forward, and if the main body of the small electronic computer 7 is slid leftward, the cursor 13 also moves to the left side of the display surface 12.
By doing the above, the movement of the virtual screen 8 and the movement operation of the cursor 13 are convenient and suitable for human senses.

A flowchart of software relating to the XY direction input section for realizing the above-mentioned function will be described. FIG. 2A shows the coordinates of the window display. A partial area of the virtual screen 8 displayed on the display surface 12 of the small computer 7 of this example corresponds to the window of FIG. 2A.
FIG. 2B is a flow chart of software relating to the movement of the window of the XY direction input system and the movement of the cursor when executing calculation (for example, table calculation) using the virtual screen 8. In the figure, when the small electronic computer 7 is turned on, the window and cursor coordinates are automatically initialized in the small electronic computer 7 (16).

Next, the displacement amount (sensor output) from the XY direction input device is read, that is, the change in the rotation amount of the ball 15 is read, and the coordinates of the window and the coordinates of the cursor 13 are changed. This calculation is time-divisionally executed concurrently with the calculation of the small computer (17).

When it is desired to change the position of the window, the switch (a)
In order to bring the window to a predetermined position by sliding the main body of the electronic computer 7 to the desk or the like while pressing 9, the rotation amount corresponding to the coordinate change amount of ΔX and ΔY is applied to the ball 15 of the XY direction input device. give. At this time, the coordinates of the cursor 13 also change at the same time by the same amount (19).

When it is desired to change the position of the cursor 13, the switch (b) 10 is held and the computer 7 is operated in the same manner as described above.
Slide the body to the desired location. At this time, the coordinates of the window do not change (20). In the processing of the above item (20), a control algorithm is incorporated in the program so that the cursor 13 does not get out of the window and the position is not lost (21).

Bring the cursor 13 to the item name or numerical value column of the desired process (for example, mode selection, numerical value input, etc.) on the display screen, and press the switch (c) 11 to select or input a numerical value and execute the calculation. (18).

As described above, according to this embodiment, since the XY direction input device is incorporated in the main body, it is possible to realize a small portable electronic computer which is easy to use and excellent in operability. Further, according to this example, the algorithm of the program for the XY direction input system is devised so that the sliding operation of the small computer main body and the degree of displacement of the window and the cursor are sensibly adapted, so that large-scale spreadsheets are also small. It can be handled smoothly on the display screen of the computer. Further, according to this example, a spreadsheet program by a small portable electronic computer, which has been difficult in the past, can be easily handled. The present invention is not limited to the above-described embodiments, and it goes without saying that various other configurations can be adopted without departing from the gist of the present invention.

[0016]

According to the present invention, the display screen is scrolled with the movement of the electronic computer, and a part of the display screen information is displayed on the display screen. Therefore, the electronic computer having a small display device is provided. However, there is an advantage that relatively large-scale spreadsheets can be performed.
