When program data to be updated are input in an operation control device 200, the program data are transmitted to a main controller. The program data are received by a communication port 27 of a main control device 100, and the received program data to be updated are stored in an external memory 21. Then, when it is confirmed that the program data to be updated are normally stored in the external memory 21, the program data to be updated stored in the external memory 21 are transferred to a flash memory 28, and the existing program data stored in the flash memory 28 are rewritten with the program data to be updated.
