PURPOSE: To obtain a loading and unloading apparatus which reduces the number of components disturbing the loading and unloading operation of a cooling fan and a smoothing capacitor. CONSTITUTION: An opening 13 is formed in the rear face plate 4 which communicates with cooling fans 11 and which comprises wind holes 4a, and a terminal stand 12 is faced. A space in which the rear surface of terminal stands 12a, 12b is attached to the upper part from the surface of the cooling fans 11 and in which the cooling fan 11 on the left side is removed is ensured. A fixing plate 21 which is bent to the edge of the rear surface plate 4 and a mounting plate for the cooling fans 11 are made freely detachable by a screw 23. A partition plate 16 is arranged between the rear of the terminal stands 12a, 12b and the front of the cooling fans 11 so as to be tightened together by the screw 23. The cooling fan 11 on the right side is made slidable along the rear surface plate 4. After a front plate 5 has been removed, external wires 15 are removed. Then the screw 23 is removed, the fixing plate 21, the mounting plate 22 and the partition plate 16 are separated. Then the partition plate 16 is pulled out, the cooling fan 11 on the left side can be removed from a box body 6. When the cooling fan 11 on the right side is slid along the rear surface plate 4, it can be removed from the box body 6. |
