  At this time, the placement position of the electronic paper 11A (11B) on the tablet 14 is determined by the coordinates of the positions of the calibration pointers 26a to 26d formed by the electromagnetic induction coils being detected by the tablet 14. The positional deviation of the coordinates from the mounting position is calculated and detected by the control device 28 of the electronic underlay 12A (12B).

  As a result, the coordinate position detected by the tablet 14 of the electronic underlay 12A (12B) accompanying the writing operation with the electronic pen 15 on the electronic paper 11A (11B) is the same as that of the calculated electronic paper 11A (11B). Correction is made in accordance with the amount of positional deviation from the specified mounting position, and writing locus display data is stored in the (information) storage device 21 from the communication unit 23 of the electronic paper 11A (11B) according to the corrected writing coordinate position. Then, the handwritten data display on the non-volatile display device 17 is performed.

  Also, for example, one electronic paper 11B (A) is opened on the left tablet 14L of the electronic underlay (double-sided type) 12B, and two electronic papers 11B are (C) on the right tablet 14R. In the state of being overlaid in the order of (B), the back side overlap detection sensor 25L of the electronic paper 11B (A) on the left tablet 14L detects light reception and determines that there is no overlap, and the calibration pointer Since the coordinate position is detected by the tablet 14L by 26a to 26d, the electronic paper 11B (A) is determined to be valid (active) on the left side of the electronic underlay (double-sided type) 12B.

  For the two electronic papers 11B (C) (B) superimposed on the right tablet 14R, any electronic paper 11B (C) (B) is detected by the tablet 14R by the calibration pointers 26a-26d. On the other hand, since the light reception is detected only by the front side overlap detection sensor 25R of the electronic paper 11B (B) and it is determined that there is no overlap, the electronic paper 11B (B) is the electronic underlay (double-sided type) 12B. It is determined to be valid (active) on the right side.

  When there is neutral electronic paper 11B, the front and back side overlap detection sensors 25R and 25L detect light reception and determine "no overlap", while electromagnetic induction signals from the calibration pointers 26a to 26d. Is not detected by any of the left and right tablets 14L, 14R in the electronic underlay 12B, the neutral electronic paper 11B is determined to be invalid (inactive).

  Therefore, in the control device 28 of the electronic underlay 12B, it is associated with each of the electronic papers 11B that are connected in a non-contact communication via the electromagnetic induction unit, and the respective IDs (A), (B), and (C). By detecting the overlap presence / absence detection by the overlap detection sensors 25R and 25L, the active presence / absence detection by the calibration pointers 26a to 26d, and collecting and managing each paper size, effective (active) electronic data on the left and right tablets 14L and 14R are collected.
