Abstract

PROBLEM TO BE SOLVED: To prevent position information from being transmitted to a computer except at the time of usage by providing a leg whose tip is movably fitted freely movably forwards and backwards on the base surface of a mouse and giving pressing force to such as degree that the mouse and a track ball are floated from a running surface to the leg. SOLUTION: A part of the track ball 2 is exposed on the base surface of the mouse 1 and the mouse 1 is slid on the traveling surface so that the ball 2 is rotated. The leg 10 for floating the mouse 1 and the ball 2 from the traveling surface is constituted by providing a pin 11 which is fitted freely movably forwards and backwards towards the base surface of the mouse 1 and by giving pressing force in a projecting direction to the pin 11 from a coil spring 12. Then, the mouse 1 and the track ball 2 are floated from the running surface by the leg 10 at the time of non-usage so that the track ball 2 is not rotated carelessly. In the meantime, when a hand is put on the mouse 1 at the time of usage, the leg 10 is easily saved by the pressure and the mouse 1 is normally used.

FIELD OF THE INVENTION The present invention relates to an improved creation of a mouse for use in a computer.

[0002]

2. Description of the Related Art A mouse is widely used as a hand-held relative position input device for operating a computer. As shown in FIG. 13, this mouse is a trackball 100 that is built into the mouse and rotates by contact with a running surface.
In the X and Y directions are converted into rotations of an X-axis roller 101 and a Y-axis roller 102 that rotate in contact with the X-axis roller 101 and the Y-axis roller 102, and the rotation amounts of these are respectively converted into an X-axis side encoder 103.
And converted into an electric signal by the Y-axis side encoder 104,
It has the function of outputting this to a computer.

[0003]

A mouse is used for moving a cursor of a computer or drawing by CAD. However, since the position is input by rotating the trackball, do not touch the mouse. Even when stationary on a desk, a slight momentum or vibration could cause the trackball to slightly rotate, causing unintended position information to be input to the computer. Especially,
This also causes a problem of moving the screen in 1-pixel units.
This is a problem that cannot be overlooked in the case of drawing by D.
Unlike the digitizer, which is an absolute position input device,
In the case of a mouse, once the relative position information was entered, it could not be moved back.
