Claims

[Scope of utility model registration request]

a first position detection surface made up of a plurality of optical fibers arranged parallel to each other, a second position detection surface made up of a plurality of optical fibers orthogonal to the optical fibers and in contact with the first position detection surface, and each of the optical fibers a light emitting element disposed at one end of each of the optical fibers; a light receiving element disposed at the other end of each of the optical fibers for receiving light from the light emitting element; and a signal applied to the first position detection surface from the can light receiving element. A pressure-sensitive drawing pad comprising position calculation means for detecting the position of pressure.
