Abstract
An electronic apparatus of the present invention has an electric fan in a casing. This electric fan generates air current between circuit substrates. The air current passes through the left-side gaps between the circuit substrates, and reaches the backside face of the electronic apparatus. The air current then passes through a power source substrate attached to a backside panel, and moves to the right. The air current then moves along the right-side inner surface and returns to the front side. The returned air is guided by a plurality of inner fins and then supplied to the electric fan. The heat generated in the casing is cooled by the air current circulating in the casing, and then conducted to the entire inner wall of the casing. The heat of the casing is then released into the atmospheric air through radiation fins arranged on the front face of the casing, the left and right side faces of the casing, and the front face of an open-close cover.
