Abstract

PURPOSE:To reduce the quantity of a program as a whole by transferring the contents of an in-process information memory to a controller and reproducing an operating in-process state before an interrupting operation to the controller and a display. CONSTITUTION:A business interruption controller 7, at the time of operating the business selecting part 9 of an input device 6, stacks picture information displayed on the display 6 and the contents of an operating information buffer in the controller 4, in the in-process information memory 8. At the time of operating a business return key 11, the latest data is taken out from the stack in the in-process information memory 8, displayed picture data is displayed on the display 5 and operating hysteresis information is transferred to the controller 4. The controller 4 views the contents of the operating history information and is reset to the business in-process state before the interruption when the executed business is not completed before the interruption. When the contents of the operating hysteresis information are completed, they enter a business selection waiting state immediately. Thereby, the interrupting operation can be executed and the quantity of the program can be reduced without incorporating an algorithm considering an operation procedure in the respective business programs.
