1. A contact-pressure detecting apparatus, comprising:
- a base having an arbitrary shape with a hollow space therein;
at least one area on a surface of the base having a polygonal periphery;
pressure sensors located at three or more vertices of each polygonal shaped area; and
a respective plate corresponding with each such polygonal shaped area of the surface of the base, each plate covering its respective polygonal shaped area of the surface of the base, each plate sandwiching the at least three pressure sensors between the plate and the base;
a calculating section positioned within the hollow space, the calculating section deriving pressure measurement information and position of pressure application information from the pressure sensors.

Abstract
There is provided a contact-pressure detecting apparatus including a base, at least three pressure-sensitive sensors, and a plurality of plates. The base has an arbitrary shape. The at least three pressure-sensitive sensors are provided on different vertex positions of a polygon having at least three corners, respectively, the polygon being set on each of a plurality of areas partitioning at least part of an area on a surface of the base. The plurality of plates are arranged corresponding to the areas of the base, respectively, the plurality of plates covering the surface of the base by sandwiching the at least three pressure-sensitive sensors with the base.
