<p>PURPOSE:To obtain a compact and thin data input/output device at the low cost by unifying together a display part and a keyboard of an information processor without using any extra parts and providing a keyboard function to the display part. CONSTITUTION:The display parts 11-15 are allocated with a data display area 16 and a keyboard input area 17 where an array of keys is displayed under the control of 8 program. A coordinate position detecting part is added to detect a coordinate position when an optional key of the key array displayed in the area 17 is touched on a screen together with a key recognizing part which specifies the key touched on the screen based on the signal produced at the coordinate position detecting part.</p> |
