1. An underlay body, comprising:
- a surface on which a writing medium is placed,wherein the writing medium includes a plurality of concavities and a plurality of convexities,wherein the plurality of concavities and a plurality of convexities record identification information of the writing medium;
a sensor configured to detect a pressure distribution on the surface,wherein the sensor comprisesa flexible conductive layer,an electrode layer that comprises at least one intersection area, anda plurality of structures to separate the flexible conductive layer and the electrode layer,wherein the electrode layer includes a plurality of first electrodes in a first direction and at least a second electrode in a second direction,wherein the plurality of first electrodes intersect at least the second electrode in the at least one intersection area,wherein at least one structure of the plurality of structures is on the flexible conductive layer and opposed to the at least one intersection area, andwherein the at least one structure of the plurality of structures is in a third direction perpendicular to both the first direction and the second direction; and
a processing section configured to acquire the recorded identification information from the plurality of concavities and the plurality of convexities, based on the detected pressure distribution.
