PROBLEM TO BE SOLVED: To easily adapt the design of a module to functional requests by pilling up mother boards and the electronic circuit boards on each other thereby forming the pile of pyramid-shaped sections as a whole. SOLUTION: A rack for an electronic circuit board includes electronic circuit boards 2A-2C connected to mother boards 3A-3C. The mother board is arranged on at least two faces parallel with a whole face 6 of a cabinet 9, and each face includes a singular or plural mother board or boards. The faces are piled up on one another, forming a pyramid-shaped pile, and the apex of the pile consists of a mother board small in surface area or an assembly of mother boards. Accordingly, the rack 1 for an electronic circuit boards 21-2C includes large-sized mother boards 3A-3C, where female connectors 4A-4C are fixed to the small-area face. Hereby, it becomes possible to easily adapt the design of a module to the functional request. |
