<p>PURPOSE: To convert a character, a numeral, and a graphic which are being inputted into a digital signal and input it directly to a computer or to make computer operation easy and accurate. CONSTITUTION: A small sphere 1 has nonmagnetic bodies 2 and extremely small magnetic bodies 3 mixed nearby the surface of the sphere while having many extremely small magnetic bodies 3 on the top surface at nearly equal intervals to make electromagnetic discrimination possible. The small sphere 1 is inserted loosely in a holder A so that the small sphere can roll in all directions. Further, a 1st magnetic force converting means 5 and a 2nd magnetic force converting means 6 which measure the X-axial rolling direction and Y- axial rolling direction of the nonmagnetic bodies 2 and extremely small bodies 3 electromagnetically and converts the measurement results into electric signals are incorporated.</p> |
