ABSTRACT:
An exhaust device 10, which is arranged on the upper surface of the main unit frame 11 of an electronic copying machine, a printer, or the like, is constructed with a louver 15 having a section in an approximately spherical shape, with an air exhaust fan 18 arranged in the space under the louver 15. Moreover, the louver 15 mentioned above is provided with a large number of slits 16 formed along its arc-shaped structure, and, with these slits 16, the exhaust device can secure an exhaust port even when another object is placed on the louver 15 mentioned above because the slits 16 will not be obstructed completely even in such a case.
