<p>PURPOSE:To input and erase data from a small area to a large area of a pressured part by laminating plural position detecting parts each of which consists of two flexible sheet-shaped electrode groups and providing a means which switches the signal input from each laminated position detecting part. CONSTITUTION:Two kinds of electric signal are obtained from position detecting parts 11 and 15 at the input time when the pressured part is small area, and one kind of electric signal is obtained from only the position detecting part 15 at the input time when the pressured pat is a large area. The position detecting part 11 is automatically selected by a signal selecting circuit 21 in case of two kinds of electric signal, and the position detecting part 15 is selected similarly in case of one kind of electric signal. Coordinate positions to which a pressure is applied continuously or interruptedly are converted to electric signals successively in accordance with graphic patterns such as characters and curves to be inputted or erased and are detected. The data processing, picture display, erase, etc. are performed on a basis of this graphic data.</p> |
