PURPOSE: To eliminate faults of being easily subject to damage by bend and friction by utilizing rigid material for the 2nd detection board in the system with a resistant board, attaining the reduction of input strain over a long period.
CONSTITUTION: Due to pressurization by a pen 2, the 1st detection board 1 consisting of a polyester film, etc., is bent at a pen input point A, and also when the pen 2 is to travel, friction is produced in a travel direction at pen input point A. The 2nd detection board 9, consisting of rigid material such as a glass board, will not be bent, and because the 1st detection-board 1 bend finishes at the point contacting with the 2nd detection 9, the damage by the 1st detection- board 1 bend is controlled in minimum. Further, friction by two detection boards 1 and 9 is reduced, thereby damage by these boards being also reduced.
