<p>PURPOSE:To easily make the actual motion of a mouse coincident with the motion of a point on a CRT by putting a mouse main body in an external box so that its center position of gravity is eccentric, and making it rotatable and providing a rotation stopper. CONSTITUTION:The mouse 1 on a column is put in the external box 2 and a rotary ball 5 is provided to enable the mouse to rotate and a weight 3 is provided to its peripheral end part to make the center of gravity eccentric. The external box 2, on the other hand, is provided with operation buttons 5 and rotation stopper 6. This constitution easily makes the motion of the mouse 1 coincident with the motion of the point on the CRT. Namely, when the mouse 1 slants to a user, the mouse 1 is slanted toward the user side by optional angles A and B to a horizontal plane 8. At this time, the mouse 1 is stopped by pressing the stopper 6 and then returned to the horizontal plane 8. In this state, the mouse 1 is only moved in an X- or a Y-axial direction.</p> |
