Abstract
Elongated top panel heat dissipation slits each include a first long side sidewall that extends in a depth direction of a first long side, and a second long side sidewall that extends in the depth direction of a second long side. For example, the second long side sidewall is provided with projection portions that protrude toward the first long side sidewall. Then, step portions are formed. The step portions incline to a lower side as the step portions extend away from printed circuit boards. An inclined rib inclining to a lower side in an extension direction of a casing locates near lower end portions of the step portions.
