<p>PURPOSE:To improve response performance in appearance to an operator by reading out and analyzing the content of a display request state preservation buffer and providing a display control part which displays the result of the analyzing on a display part and a display state preservation buffer which writes and preserves a display state. CONSTITUTION:This device is equipped with a display request buffer 15 which stores display request data, the display control part 16 which reads out and analyzes the content of the display request state preservation buffer 14 and displays it on the display part 13 based on the analytic result, and the display state preservation buffer 17 which writes and preserves the display state. When the number of times of write exceeds the regulated number of times, the display control part 16 is called, and the content of the display request buffer 15 is read out and analyzed by the display control part 16. The content is displayed on the display part 13 based on the analytic result, and also, a displayed state is written on the display state preservation buffer 17, then, it is preserved. Thereby, it is possible to improve the response performance in appearance for the operator.</p> |
