Information input device

摘要

In a reading device (2), a cover sheet (101) is positioned by a recessed portion (71) such that almost the whole surface of the cover sheet (101) faces a detection device (7). A cover sheet (102) is positioned by a recessed portion (81) such that almost the whole surface of the cover sheet (102) faces a detection device (8). Information that is written on a paper sheet (103) overlapping with the cover sheet (101) is acquired based on a position of an electronic pen (3) detected by the detection device (7). Information that is written on the paper sheet (103) overlapping with the cover sheet (102) is acquired based on a position of the electronic pen (3) detected by the detection device (8).
