PURPOSE:To enable various layouts of an operation/display unit by dividing an upper printing board into plural printing boards provided with connectors, and disposing, on a lower printing board, a plurality of connectors corresponding to the connectors of the upper printing boards in different positions and directions. CONSTITUTION:An upper printing board is divided into plural pieces of printing boards 1, 2 provided with connectors 7, 8, respectively. A lower printing board 3 is provided thereon with a plurality of connectors 9a, 9b and 10a, 10b corresponding to the connectors 7 and 8 of the printing boards 1 and 2 in different positions and directions. In the case of lateral layout of an operation/display unit, the connectors 7, 8 of the boards 1, 2 are engagingly fixed in the connectors 9a, 10a of the board 3, respectively. Meanwhile, in the case of longitudinal layout, the connectors 7, 8 are engagingly fixed in the connectors 9b, 10b, respectively. The disposition of the connectors 9b, 10b in a direction perpendicular to the connectors 9a, 10a enables the longitudinal layout. |
