Further, another invention provides a mouse body having a coordinate value data generator that generates coordinate value data according to movement and a changeover switch that outputs a switching command signal, as well as a pointer position setting device and a scroll position setting device. position setting means for alternately selecting the pointer position setter and the scroll position setter to move the mouse pointer and scroll the display screen each time a switching command signal sent from the changeover switch is input; It is equipped with the following.

(Function) Therefore, the present invention takes the above measures, so that when coordinate value data is generated from the coordinate value data generation section as the mouse body moves, the scroll position setting device determines the direction of change of the coordinate value data and The display screen of the display device is scrolled by setting the position in a scroll direction and scroll speed according to the change speed.

Further, in another aspect of the invention, a pointer position setting device and a scroll position setting device are provided, and when the pointer position setting device is selected by a switching command signal sent from the changeover switch, the pointer position setting device controls the scroll position setting device. When the scroll position setter is selected by setting the position in a direction and speed corresponding to the direction and speed of change of the coordinate value data and moving the mouse pointer, this scroll position setter will move the mouse pointer according to the movement of the mouse body. The display screen of the display device is scrolled by setting the position in a scroll direction and scroll speed corresponding to the direction and speed of change of the obtained coordinate value data.

(Example) Hereinafter, an example of the apparatus of the present invention will be described with reference to the drawings. That is, in this scroll control device, as shown in FIG. 1, a display device 10 and a mouse body 20 are electrically connected, and the display device itl.

A display surface 11 such as a display for displaying a display screen and a position setting section 12 for setting the position of the display screen and mouse pointer based on signals from the mouse body 20 are provided on a part of the side. On the other hand, as shown in FIGS. 2 and 3, on the mouse body 20 side, for example, a mouse button switch 21 that generates a permission signal when pressed, a mouse button switch 22 that generates a disapproval signal when pressed, and a switching command signal. A changeover switch 23 is attached that generates X, and as the mouse body 20 moves,
A coordinate value data generating section 24, such as a conventionally known optical type or mechanical type, which generates Y coordinate value data is provided.

The position setting section 20 alternately selects two output terminals each time it receives a switching command signal generated from the changeover switch 23, and outputs the coordinate value data from the coordinate value data generation section 24 from the selected output terminal. a pointer position setting 2ii16 that sequentially specifies the mouse pointer position in response to coordinate value data when the mouse body 20 is moved in a desired direction; It is composed of scroll position setting "a17" etc. that are sequentially specified.Although not shown in the display device 1flo, position setting data corresponding to the coordinate value data sent from the setting $16゜17 is stored. a memory or counter to display, an image memory to store the display screen, and a CPU to execute a predetermined program.
etc. are built-in.

Next, we will discuss the operation of the device configured as described above in the fourth section.
This will be explained according to the diagram. Now, when the selection means 15 selects the pointer position setting device 16, if the mouse body 20 is moved in an arbitrary direction as shown in FIG. The X, Y coordinate value data is sent to the pointer position setting device 16 via the selection means 15, where it is converted into a pointer position setting signal according to the coordinate value data, and sequentially stored in, for example, a memory of the display device 10, or updated. Store it while doing so. Here, display device 1
The 0-side CPU moves the mouse pointer 14 on the display screen 13 according to the moving direction and moving speed of the mouse body 20 while sequentially reading out the contents of the memory according to the program. Then, when the mouse body 20 stops and the mouse pointer 14 is set at a desired designated position, the data etc. at the designated position are corrected based on the program.

In the above state, when the changeover switch 23 of the mouse body 20 is depressed as shown in FIG. 4(b), the changeover command signal is output from the changeover switch 23.
This allows the selection means 15 to set the scroll position 817.
Choose a side.

Therefore, after the suppression operation of the changeover switch 23, as shown in FIG.
When the mouse body 20 is moved in a desired direction as described above, the coordinate value data generating section 24 generates coordinate value data that changes quickly according to the moving direction and the moving speed of the mouse body 20, as described above. The signals are generated sequentially and sent to the scroll position setter 17 through the selection means 15. The scroll position setter 17 sequentially stores or sequentially updates and stores position designation signals corresponding to input coordinate value data in the memory of the display device 10, and at the same time sequentially reads out the contents of the memory to designate a position on the display screen 13. Therefore, the display screen 13 is sequentially scrolled in a scrolling direction and scrolling speed corresponding to the moving direction and moving speed of the mouse body 20. FIG. 4(d) shows the display screen position after scrolling.

After scrolling the display screen 13, if the changeover switch 23 is pressed again, this time the changeover switch 23
The original state, that is, the pointer position setter 16 is selected by the switching command signal from the mouse pointer 14, and the movement of the mouse pointer 14 can be controlled.

Therefore, according to the configuration of the above embodiment, when receiving the coordinate value data generated according to the moving direction and moving speed of the mouse body 20, the scroll position setting device 17 adjusts the moving direction and moving speed of the mouse main body 20. Since the display screen is scrolled while sequentially setting the position in the corresponding scroll direction and scroll speed, the display screen can be freely scrolled in the moving direction of the mouse body 20, and the moving speed of the mouse body 20 and the speed of the display screen 13 are Since it is synchronized, it provides a sense of unity with the operator's operations, and in turn matches human sensibilities, and is very easy to operate, greatly contributing to improving the efficiency of, for example, design work.

Furthermore, since the mouse pointer 14 can be freely moved while sequentially specifying the position with the pointer position setting device 16 based on the coordinate value data accompanying the movement of the mouse body 20, the mouse pointer 14 can be moved in the direction of movement of the mouse body 20. and can be moved in a direction and speed depending on the movement speed. Moreover, the pointer position setter 16 and the scroll position setter 17 are provided, and the two-step position setter 16° 16 is alternately selected each time the selector switch 23 on the mouse body 20 side is operated. Not only can the pointer 14 be moved in any direction, but especially when the scroll position setter 17 is selected, the scroll position setter 17 is moved to a position based on coordinate value data sequentially generated as the mouse body 20 moves. , the entire display screen can be scrolled in accordance with the designated position, that is, in a scrolling direction and scrolling speed corresponding to the moving direction and moving speed of the mouse body 20, which is extremely useful. Furthermore, since only the mouse body 20 is used, hand movements are not interrupted and the mouse can be easily operated with one hand. Furthermore, the conventional control keys with icons are no longer required, and the space on the display screen can be used more effectively.

Note that the present invention can be implemented with various modifications without departing from the gist thereof.
