ABSTRACT:
A coordinate position digitizing system comprises a position determining plate having a plurality of first conductors extending in parallel with one another at regularly spaced intervals. A plurality of second conductors also extend in parallel with one another at regularly spaced intervals and across the first conductors. Driving and controlling means are provided in common to the first conductors and the second conductors for selectively energizing in turn one or more of the first conductors and second conductors, for example, by supplying a direct current flowing therethrough. Pick-up means, such as a magnetic flux detecting means, is movably set on the position determining plate for producing a signal in response to field variations on the position determining plate caused by the selective energization of the first conductors and second conductors. Information producing means produces positional data defining a position on the position determining plate to which the pick-up means is brought close, based on the strength of the signal drived from the pick-up means.
