Abstract
A compact pointing device of a novel constitution featuring high operability. A disk-like operation unit 4 is disposed on the PC substrate 8 via an annular resilient stopper 7. Magnets 11, 12, 13 and 14 are arranged on the lower surface of the operation unit 4 along the circumference thereof maintaining an angle of 90 degrees. Hall elements 15, 16, 17 and 18 are arranged on the upper surface of the PC substrate 8 opposed to the magnets 11, 12, 13 and 14. A processing circuit is mounted on the PC substrate 8 to convert the changes in the output voltages of the Hall elements 15, 16, 17 and 18 into moving amounts of the cursor in the predetermined directions.
