PURPOSE:To shorten the wiring length of a signal line, and also, to decrease the number of wirings of a long signal line, and to prevent the wiring from becoming complicated by providing a microprocessor on an operating part side. CONSTITUTION:When a start key of an operating panel 29 is operated, a program executing circuit 49 of a microprocessor 45 controls a first serial I/O converting circuit 44 and transmits control data to a mechanism control part 42 through a serial communication bus 43. In the mechanism control part 42, when a second serial I/O converting circuit 50 receives control data from an operating part 41, various signals are outputted to a mechanism part I/O port 52 through an internal bus 51. By providing the microprocessor on the operating part side, the wiring length of a signal line for connecting the microprocessor and the operating part can be shortened, and also, the number of wirings of a long signal line at the time of connecting a microprocessor mechanism control part can be decreased, and the wiring does not become complicated. |
