Reference numeral 9 denotes a power supply for supplying power to the high-frequency generator 7. The power supply 9 is mounted at a position where the printed board 9 a is parallel to the direction of the cooling air from the blower 8 and the component 9 b to be cooled faces the blower 8. Have been. Reference numeral 10 denotes a main body frame, which has a cooling air intake 10a below the blower 8. Reference numeral 11 denotes an orifice, which has a minimum dimension that does not make contact with the cooling opening 7a of the high frequency generator 7.

外部に漏れる騒音は小さくなる。The arrows in the figure indicate the flow of the wind. In the present embodiment, since the cooling air intake 10a is located on the bottom surface of the main body frame 10, noise leaking from the cooling air intake 10a to the outside is limited only between the bottom surface of the main body frame 10 and the product table 12. Because it does not leak, clearly compared to the conventional example,
Noise leaking to the outside is reduced.
