Device for generating electric signals representing the position coordinates of a stylus on a reference surface |
摘要 |
A device for generating electric signals representing the position coordinates of a stylus on a reference surface, characterized in that it comprises a signal generator (6) that is fixed with respect to the reference surface and comprising a movable part (5) which works in conjunction with at least two potentiometers generating the voltages representing the said coordinates, the stylus (7) being a stylus for pointing on the reference surface, and mechanical linkage means being provided between this stylus and the said movable part so as to obtain a scaling down effect on the movements given to the stylus when they reach the potentiometers.
