るようになる。Next, the internal structure will be described. Reference numeral 5 denotes a partition plate horizontally provided on the upper portion of the main body 1, which also serves as a partition with a lower combustion section (not shown) and also has a plurality of locking holders 6.
Is mounted, and the printed circuit board 7 is supported through the holder 6. A power transformer 8 is mounted and hand-mounted on the printed circuit board 7 together with other control components, and is mounted on the front portion of the printed circuit board 7 at a position close to the operation circuit board 2. Reference numeral 9 denotes a projecting portion formed on the rear portion of the operation board 2, which projects up to the upper portion of the transformer 8. As can be seen from the above configuration, the projecting portion 9 supports the heavy transformer 8 when the device is tumbled, dropped, or otherwise impacted in the upward direction.

A plurality of ribs 12 are provided on the protrusion 11. And this rib 12
The front end portion 13 of the top plate 4 is supported and mounted on. Therefore, the top board 4 is supported by the operation board ribs 12 to prevent the top board 4 from being deformed, and at the same time, even if water or the like enters from the abutting portion of the top board 4 and the operation board 2, it is guttered. It is also possible to prevent the power supply transformer 8 from being received by the shaped portion 10 and hitting it.
