PROBLEM TO BE SOLVED: To facilitate the ordering job and the connection work of a cable, to easily correspond to a system change and to easily mount the units of various sizes by installing a feeding cable connecting a mounted unit to the feeding connector of a connector group, which is in the nearest position. SOLUTION: Board units 13A-E are mounted on a mounting part 11 and feeding connectors 30 are connected to a power source 12 by feeding buses 31. The plural feeding connectors 30 are collected and they form one connector group 32. A bus unit 33 scatters the connector groups 32 in the installation directions of the feeding buses 31. A feeding cable 34 connects the mounted unit to the power feeding connector of the connector group in the nearest position. The feeding connectors 30 are formed on a printed board. As the interval of the connectors in the group is narrower, the area of the printed board is required to be smaller. As the interval of the connectors in the group is narrower, the group connected to the respective board units is easily specified and workability is improved.
