<p>PURPOSE:To improve the operability by providing a key electrode for item information input altogether to an electrode forming face of a matrix contact for graphic input. CONSTITUTION:A fixed electrode base 2 and a movable electrode base 4 form matrix contacts for graphic input in the coordinate input tablet and a frame sheet spacer 3, a protecting surface sheet and a reinforcement plate are laminated to them for the assembling. A dot spacer 12 of the tablet is provided between the fixed electrode 5 and the moving electrode 6 and a couple of key electrodes 13, 14 for key contacts for item information input are formed. The key electrode 14 is led out of the connector terminal 9 and the other electrode 13 is used in common with the connector terminal 8 of the electrode 5. Thus, a hand- written input part for a graphic pattern and the key input part for item information are constitute compact and the terminals 8, 9 are used in common so as to reduce number of required terminals and wires.</p> |
