Cursor control device
First Claim
1. A cursor control device adapted for controlling a cursor on a display screen of an electronic device, comprising:
- a circuit module holder, said circuit module holder having an accommodation chamber defined therein and an opening on a top side thereof in communication with said accommodation chamber;
a sleeve sleeved onto said circuit module holder and movable leftwards and rightwards relative to said circuit module and rotatable forwards and backwards relative to said circuit module;
a circuit module accommodated in said accommodation chamber of said circuit module holder, said circuit module comprising a circuit board, a sensor module installed in said circuit board and adapted for sensing the direction and amount of movement of said sleeve relative to said circuit module holder and producing a signal indicative of the direction and amount of movement of said sleeve relative to said circuit module holder, and a microprocessor installed in said circuit board and electrically connected with said sensor module for receiving the signal produced by said sensor module and producing a control signal for controlling said cursor on said display screen subject to the signal received from said sensor module.
