COORDINATE POSITION DIGITIZING SYSTEM ABSTRACT OF THE DISK CLOSURE A coordinate position digitizing system comprises a position determining plate having a plurality of first conductors extending in parallel with one another at intervals of a regural space and a plurality of second conductors also extending in parallel with one another at intervals of a regular space and across the first conductors, driving and controlling means provided in common to the first conductors and the second conductors for energizing selectively in turn one or more of the first conductors and second conductors, for example, my supplying a direct current flowing therethrough, pick-up means, such as magnetic flux detecting means, movably set on the position determining plate for producing a signal in response to phenomenal variations on the position determining plate caused by the selective energization of the first conductors and second conductors, and information producing means for producing positional data defining a position on the position determining plate to which the pick-up means is brought close on the strength of the signal derived from the pick- up means.
