1. A coordinate input apparatus comprising:

  • a coordinate plate having a plurality of pieces of coordinate information each corresponding to an X-coordinate value and a plurality of pieces of coordinate information each corresponding to a Y-coordinate value, said plurality of pieces of coordinate information are independently and intermittently recorded on said coordinate plate;

    input-indicating means for indicating a position of the coordinate plate to be input and for detecting coordinate information in the vicinity of the position; and

    processing means for determining X-coordinate values and Y-coordinate values from the coordinate information detected by said input-indicating means and for determining the coordinate of the input position on the basis of the X-coordinate values and Y-coordinate values.
