Claims

[Claims for Utility Model Registration] 1. In a scanning exposure type copying device having an exposure lamp which is movable in the scanning direction and whose longitudinal direction is perpendicular to the scanning direction, and a document table glass which is provided parallel to the lamp, A blower fan is provided on the main body frame in the longitudinal direction of the lamp, and an air path of the blower fan is provided in parallel with an air path to a specific area perpendicular to the scanning direction of the document platen glass and an air path to the charged electrode. An in-flight blower mechanism for an electrophotographic copying device characterized by: 2. Utility model registration claim 1, characterized in that the specific area is an area of the document table glass near the exposure lamp when the exposure format of the electrophotographic copying device is switched to exposure lamp stationary scanning. The in-flight fan mechanism of an electrophotographic copying machine. 3. The electronic device according to claim 1, wherein the specific area is an area of a document platen glass where exposure lamp irradiation time is long when the exposure type of the electrophotographic copying device is an exposure lamp traveling type. The in-flight fan mechanism of a photocopying machine.
