<p><P>PROBLEM TO BE SOLVED: To provide an electronic apparatus provided with a centrifugal fan device capable of improving an air flow and static pressure by increasing a flow rate to a centrifugal direction when the centrifugal fan device is disposed in a narrow space, intervals with members disposed oppositely to each intake port are different, and the balance of the air duct resistance of a space between the oppositely disposed members. <P>SOLUTION: A cylindrical section upper side pressure surface tip Ea of a blade 19a facing an intake port having a narrower interval with the oppositely disposed member is positioned at a fan rotation direction indicated by an allow R of a lower pressure surface tip Eb of the blade 19a facing an intake port having a wider interval with the oppositely disposed member. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
