Title:
DIGITAL DATA RECORDING PAPER
Document Type and Number:
Japanese Patent JP3407004
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To attain accurate and quick image processing by forming many section marks arranged at a prescribed interval adjacent to X axis direction base lines and Y axis direction base lines.
SOLUTION: A light emitting side (transmitter side) A generates a section mark ray P and a binary signal mark ray Q and emits rays P, Q, R toward a light receiving side (receiver side) B. A mirror C is arranged as required between the light emitting side A and the light receiving side B to select a transmission line. The section mark ray P is used to indicate many section marks KP arranged at a prescribed interval in 2-dimensional directions. The binary signal mark ray Q is used to display analogically a binary signal mark KQ in a mark area F, decided by a range surrounded by the section marks KP. An additional mark ray R indicates an additional mark KP representing a data transmission range and a 2nd additional mark ray S indicates a 2nd additional mark KS representing a read direction.
