<p>A dustless mouse comprises: a circuit (17), a horizontal conic rolling wheel (18), a vertical conic rolling wheel (19), a pressured conic rolling wheel (20), a round ball (21) and a shell, when the prior mouse is slid, then the rubber round ball will roll, thus it will friction with pulleys on all parts thereof, therefore, user's commands are transferred and completed. However, for a long time, the dust will accumulate between the pulleys and the rubber round ball so to reduce the sensitivity of the mouse, in consequence, the cursor on the screen will not easy to move. In the present invention, an improvement is performed, in which a conic rolling wheel is used to substitute the pulley so that the angle between the conic rolling wheel and the rubber round ball is enlarged, therefore, the conic tip will not easy to accumulate dust and dirt, thus the dust and dirt are not easy to accumulate between the rolling wheel and rubber round ball. The sliding function of the mouse is also not affected. Thus the dustless mouse effect is achieved. <IMAGE></p> |
