<p>PURPOSE:To input/output a pattern simply by providing the titled device with a Y electrode plates having many electrodes on its substrate, a pressure sensitive conductive plate changing its electric resistance value in accordance with pressing force and many film-like X electrodes developing colors when voltage is applied between upper and lower surfaces. CONSTITUTION:A Y electrode plate 22 having many electrodes in the Y direction, a pressure sensitive conductive plate 23 changing its electric resistance in acoordance with the pressing force, recording paper 13 developing colors when voltage is applied between the upper and lower surfaces and a transparent or translucent film-like X electrode plate 27 having many electrodes in the X direction are laminated on a substrate 21 having a prescribed plane area. At the transmission time, voices are transmitted through telephone sets and a pattern is drawn in a drawing part 11 with a pen. When the pen 17 is separated from the plate 27, the mode is automatically changed to receiving status. When an opposite signal is inputted from an I/O terminal 36, the intersected points of respective electrodes 28, 24 on the plates 27, 22 are selected by scanning devices 31, 32 and the voltage of a power supply is applied to the selected parts, so that the transmitted picture is displayed.</p> |
