<p>PURPOSE:To easily and quickly correct the displayed numeric characters, etc. by pushing a display area to change the display characters after providing a display means, a coordinate input means put on the display means, and an arithmetic processing means. CONSTITUTION:A transparent touch panel 13 put on a liquid crystal display panel 12 is formed by putting two sheets of thin film registers with many thin spacers set every several millimeters. Then the voltage of several volts is impressed to the vertical and horizontal terminals from a CPU 15. While the voltage signals are delivered for both axis X and Y in response to the pushed coordinate position on the panel 13. These electric signals are digitized by an A/D converters 16 and 17 and supplied to the CPU 15 respectively. Then the CPU 15 serves as an arithmetic processing means to display the input coordinate data on the panel 12 and also correct the data via the panel 13. In such a way, the displayed numeric characters, etc. can be easily and quickly corrected.</p> |
