PURPOSE:To enable even an inexperienced operator to perform accurate and easy operation, by displaying a guidance that the operator follows entirely in concrete form on a display part. CONSTITUTION:When a key on a keyboard 10 is operated, a keyboard control part 11 discriminates the operated key to output a corresponding operated-key control signal to a main control part 12. The main control part 12 discriminates the operated key control signal from the control part 11, and outputs it to an application control part 13 when recognizing that the input signal is a mode operated key control signal based upon a mode key. The application control part 13 accesses a display file 14 containing various display items to be displayed on a PDP17 on the basis of respective flows of mode key operation to read display items selectively, and a display buffer 15 holds them. The application control part 13 controls a PDP control part 16. |
