A digital data reader of digital data recording sheet comprising: Y-axis internal line calculating means for correcting a discrepancy of angle of inclination relative to a Y-axis internal line and an X-axis basic line, compared with an angle of inclination of a Y-axis external line and a Y-axis basic line relative to the X-axis basic line in a display area, and calculating a plurality of Y-axis internal lines whose starting points on the X-axis basic line are decided ; X-axis internal line calculating means for correcting a discrepancy of angle of inclination relative to an X-axis internal line and the Y-axis basic line, compared with an angle of inclination of an X-axis external line and X-axis basic line relative to the Y-axis basic line in a display area, and calculating a plurality of X-axis internal lines whose starting points on the Y-axis basic line are decided; mark area basic point detecting means for obtaining a mark area basic point by calculating an intersecting point of the Y-axis internal line and X-axis internal line, and mark area calculating means for calculating a mark area in response to the mark area basic point calculated by the mark area basic point detecting means; whereby data of the digital data recording sheet can be read accurately responsive to deformation of the display area due to expansion and contraction of the digital data recording sheet.
