欠点を有していた。 Therefore, to cool the internal equipment of the casing 1, a blower 6 is provided, and piping 6A and 6B are installed from the blower 6 to the mechanical part 2 and the package gate part 3, respectively, and the blower 6 is driven to rotate. 1
Outside air is taken in from A in the direction of arrow A and is blown to the mechanical section 2 through piping 6A and to the package gate section 3 through piping 6B. The air blown into the mechanical part 2 is transferred in the direction of arrow C and is discharged out of the casing 1 through the exhaust hole 1B. Further, the air blown to the package gate section 3 passes through the power supply section 4, is transferred in the direction of arrow B, and is discharged from the exhaust hole 1B in the same manner as described above. However, in such a configuration, although the air transferred to the vicinity of the exhaust hole 1B is exhausted, for example, the air sent out in the direction shown by the arrows D ₁ D ₂ is not exhausted. Therefore, there was a problem in that the temperature rose due to the air remaining inside the housing 1 and the cooling effect was poor. Moreover, it has the disadvantage that a large blower must be provided in order to prevent such a temperature rise.
