PROBLEM TO BE SOLVED: To effectively release heat generated from a low voltage power source with a simple structure which is easily downsized in am image processing device including the low voltage power source for stepping down a voltage from an external power source and outputting the voltage.SOLUTION: A low voltage power source substrate 300 is covered by a metal cover 320, and a heat conduction plate 330 facing a fan 400 from the outer side is connected with the low voltage power source substrate 300. The heat conduction plate 330 includes openings 331 between blades 510 of a louver 500. The structure allows heat generated by the low voltage power source substrate 300 to be smoothly transmitted to the heat conduction plate 330 through a cover 320 and the heat is effectively released by air from the fan 400 which passes through the openings 331. |
