Abstract

PURPOSE: To improve the reliability of the whole equipment, by supplying the power from two independent power sources which are mutually connected to the circuit for storing the communication information of the data bus.
CONSTITUTION: As for the interface IF control circuit 2 of the main control part and the mechanism part, the microprogram μPG control circuit 4, and the mechanism parts 10, 12, the power is supplied from the electric power source unit 15, and as for the IF control circuit 3 of the auxiliary control part and the mechanism part, the μPG control circuit 4, and the mechanism parts 11, 14, the power is supplied from the electric power source unit 16. As for the memory parts 6', 7' for storing the communication information and the common mechanism part 13, the power is supplied from the electric power source units 17, 18 which have been mutually cross-called. In case when the power source unit 15 has broken down, it is changed to the auxiliary side, and the auxiliary side is operated by supplying the power from the power source 16. The memory parts 6', 7' are constituted so that the same contents are stored, and even in case of changing to the auxiliary side from the main side, the operation can be continued immediately. Accordingly, even if one of the power sources 17, 18 has broken down, the operation can be continued by the other power source, and therefore the reliability is improved.
