The invention provides a control device, wherein the maintenance is improved, the cost is reduced, the energy is saved, and the space is saved. 1It is possible to combine several functions in a column. The space in the case 1 is partitioned into the partial spaces 1-1 and 1-2 in the lateral direction by the first partition plate (partition plate (vertical)) 7. The partial space 1-2 in the transverse direction is divided into partial spaces 1-31 and 1-32 in the vertical direction by the second partition plates (partition plates (horizontal)) 8-1, 8-2 and 8-3. , 1-33, 1-34). And the functional blocks 6-1 to 6-8 are mounted on the divided partial spaces 1-31, 1-32, 1-33, 1-34.
