ABSTRACT:
An exhaust device is used to exhaust air from inside of an apparatus to outside. The exhaust device includes a louver with blades arrayed in a lattice, the louver being detachably engaged with a trough hole in a cover of the apparatus such that the louver can rotate freely in a clockwise and a counterclockwise direction. A fan unit provided separately from the louver is positioned upstream in an airflow direction than the louver, so as not to rotate when the louver is rotated. The blades form an angle between 0° and 90° with a plane perpendicular to a central axis of the louver.
