<p><P>PROBLEM TO BE SOLVED: To provide a board case which is not remarkably large-sized even if it contains two or more boards, which respectively have a heater element, and a game machine equipped with this board case. <P>SOLUTION: First board cooling air and second board cooling air are not mutually mixed together by forming a partition wall 98 which divides a first board cooling air passage 11, through which the first board cooling air, which cools a first board 71, circulates, and a second board cooling air passage 12, through which second board cooling air, which cools a second board 72, circulates. Thereby, since a rise in the temperature of the first board cooling air by the mixing of the second board cooling air is beforehand prevented, the first board cooling air which cools the graphic LSI 71A of the first board 71, does not become higher than the desired temperature, a need for the being large-sized of a blower 86 or the enlargement of the blower is lost, and it allows reduction in size of the board case 70. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
