ABSTRACT:
The present invention is related to a cursor control device which includes a ball housing for accommodating therein a ball, a grid wheel device driven by the ball for intermittently passing therethrough a light to control a movement of a cursor, a wheel shaft device engaged with the grid wheel device and driven by the ball for transmitting the grid wheel, and an urging device engaged with the wheel shaft device for urging the wheel shaft device against the ball to assure that the grid wheel device can rotate synchronously with the ball. The present invention utilizes the urging device to exert a force on the wheel shaft device so that the transmission roller device can be urged against the ball to facilitate the close contact between the transmission roller device and the ball rather than be passively contacted by the ball.
