Abstract

PURPOSE:To simplify an electric circuit, and to easily perform an operation by providing a track ball for rough adjustment and a track ball for fine adjustment on the different faces of a main body part. CONSTITUTION:At the time of moving the position of a cursor much, a track ball 5 for rough adjustment is rotated by inclining and moving a main body part 1 so that the track ball 5 for rough adjustment can be brought into contact with a desk face. The rotational amount is transmitted to an information processor, and the position of the cursor on a display screen is moved much. At the time of moving the position of the cursor a little, a tack ball 4 for fine adjustment is rotated by inclining and moving the main body part 1 so that the track ball 4 for fine adjustment can be brought into contact with the desk face. The rotational amount of the track ball 4 for fine adjustment is transmitted to the information processor, and the cursor is moved a little. Also, the track ball 5 for rough adjustment is switched to the track ball 4 for fine adjustment by operating a changeover switch 3 in a state that the track ball 5 for rough adjustment is brought into contact with the desk face.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pointing device which is connected to an information processing apparatus such as a computer and used for designating a position on a display screen.

[0002]

2. Description of the Related Art A conventional pointing device which is connected to a computer or the like and is used for designating a position of a cursor on a display screen is provided with a single trackball for moving the position of the cursor on an upper surface of a main body or The movement amount of the cursor on the display screen corresponding to the movement amount of the trackball is adjusted electrically inside the information processing device.

[0003]

As described above, since the conventional pointing device has only one trackball for moving the position of the cursor on the display screen, the amount of movement of the trackball is limited. Adjustment of the amount of movement of the cursor on the corresponding display screen must be electrically performed inside the information processing apparatus, the electric circuit inside the information processing apparatus becomes complicated, and the operation of the pointing device is troublesome. There is a problem.

[0004]

A first pointing device of the present invention includes provision of a coarse adjustment trackball and a fine adjustment trackball on different surfaces of a main body.

A second pointing device of the present invention comprises at least one trackball and a switch section for switching the trackball for coarse adjustment or fine adjustment.

[0006]

Embodiments of the present invention will now be described with reference to the drawings.

FIG. 1 is a perspective view showing a first embodiment of the present invention, (a) is a top perspective view, and (b) is a bottom perspective view.

In the embodiment shown in FIG. 1, a click button 2 is provided on the upper surface of the main body 1 and a change switch 3 is provided on the front side surface.
Both sides of the bottom surface of the main body 1 are formed obliquely, and a fine adjustment trackball 4 and a coarse adjustment trackball 5 are provided on each of the slopes.

When the position of the cursor on the display screen is moved by the pointing device configured as described above, the following operation is performed.

When the position of the cursor is desired to be greatly moved, the main body 1 is tilted so that the coarse adjustment trackball 5 comes into contact with the desk surface, and the main body 1 is moved to move the coarse adjustment trackball 5. Rotate. The rotation amount of the coarse adjustment trackball 5 is transmitted to the information processing device,
Move the cursor position on the display screen greatly. When it is desired to move the position of the cursor by a small amount, the main body 1 is tilted so that the fine adjustment trackball 4 contacts the desk top surface, and the main body 1 is moved to rotate the fine adjustment trackball 4. Fine adjustment trackball 4
Is transmitted to the information processing device, and the position of the cursor on the display screen is moved in small increments.

The coarse adjustment trackball 5 can also be used for fine adjustment by operating the switching switch 3 with the coarse adjustment trackball 5 in contact with the desk surface. That is, by operating the switching switch 3, the coarse adjustment trackball 5 can be used for both coarse adjustment and fine adjustment, and the position of the cursor on the display screen can be changed without changing the tilted state of the main body 1. It is possible to move it large or small. The same operation can be performed on the fine adjustment trackball 4.

2A and 2B are perspective views showing a second embodiment of the present invention. FIG. 2A is a top perspective view and FIG. 2B is a bottom perspective view.

In the embodiment shown in FIG. 2, a fine adjustment trackball 14 is provided on the upper surface of the main body 11, and a coarse adjustment trackball 15 is provided on the bottom surface of the main body 11. The fine adjustment trackball 14 is directly moved by hand, and the coarse adjustment trackball 15 is rotated by being brought into contact with the desk top surface and moving the main body 11.

The functions of the fine adjustment trackball 14 and the coarse adjustment trackball 15 are the same as those of the embodiment shown in FIG. The operation of the change-over switch 13 is also the same as that of the embodiment shown in FIG.

FIG. 3 is a perspective view of the upper surface of the third embodiment of the present invention.

The embodiment shown in FIG. 3 is a trackball 2 for fine adjustment.
4 is provided on the side surface of the main body 21. The coarse adjustment trackball is provided on the bottom surface of the main body 21 as in the embodiment of FIG. The fine adjustment trackball 24 is operated with the thumb. Other configurations and operations are the same as those of the embodiment shown in FIG.

[0017]

As described above, the pointing device of the present invention is provided with two trackballs, a coarse adjustment trackball and a fine adjustment trackball, and uses these trackballs properly according to the purpose. This makes it possible to move the position of the cursor on the cursor largely or small, which simplifies the electric circuit inside the information processing apparatus and facilitates the operation of the pointing device. In addition, a change switch for switching one trackball between coarse adjustment and fine adjustment is provided, and by operating the change switch according to the purpose, the position of the cursor on the display screen can be moved greatly or small. It can be moved, the electric circuit inside the information processing apparatus is simplified, and the pointing device is easily operated.
