PURPOSE:To ensure the work processing with high efficiency, by shunting the information of a screen in case an error is produced and restoring the shunted information after the error is released. CONSTITUTION:The working is discontinued if a work processing part 10 has an error. Then a control part 20 shunt the information displayed at a display 4, i.e., the contents of a refresh buffer 3 to a storage circuit 5. Then the error processing information accordant with the type of the error is stored in the buffer 3. A message is displayed at the display 4 to process the error. Thus an operator completes the error processing based on the message. After the error processing is over, the contents of the circuit 5 are restored to the buffer 3. As a result, the work performed at a time point when the error arises is displayed at the dispaly 4. |
