<p>PURPOSE:To obtain a touched key from a key pattern and the touched position on a display screen by reading the key pattern displayed last among those key patterns which include the touched positions of the screen within their display areas. CONSTITUTION:When plural key patterns are simultaneously shown on a display device 4, the control information on the key patterns are written into a key pattern control table 32. Then the corresponding coordinate data on a display screen is outputted with a touch of a touch panel 5. A key driver 21 searches the table 32 and searches the key pattern that is shown last. Then the driver 21 decides that the searched pattern key includes a touched key and reads the key pattern data corresponding to the relevant key pattern No out of a key pattern data storage part 31. Thus a return code corresponding to the touched key is obtained from the key pattern data and the coordinate data on the touched position.</p> |
