<p>PURPOSE:To give the display and storage functions to the input plate itself, by using the pen included with conductive ink and the input plate locating diodes in matrix shape. CONSTITUTION:The control section 13 gives a generating signal to the voltage generating circuit 14 to produce the voltage signal at Y1-Y10 terminals sequentially. Thus, a voltage is fed to the U shaped electrode via a diode 9 on the selection line 10 to be scanned, and the part coated with conductive ink shows a low resistance, and a voltage is produced to the said T shape electrode 3. Thus, a voltage is produced only to the sense line 11 being conductive with the electrode 4, and the X coordinates being conductive among X1-X10 terminals of the voltage detection circuit 15 connected to the sense line 11 are detected, and they are transmitted to the control section 13. In this case, since the Y coordinate can be designated with the selection line 10, X-Y coordinate for conductive ink coated part can be obtained. Thus, the display and storage functions can be obtained. Further, the erase is easy, just wiping out is sufficient.</p> |
