のである。Since the paper paper transport device according to the present invention is configured and operates as described above, by making a slight modification to the air intake hole of the conventional paper paper transport device, air is automatically supplied only when paper is transported. Since the suction hole can be opened and closed at other times, there is virtually no flow of dust around the paper transport system, and as a result, paper dust and dust that accumulate inside the machine can be reduced. If dust such as dust and toner is stirred up and then inhaled, most of the dust will disappear, so air is provided in the exhaust hole.
This has the effect of significantly extending the life of the filter. Furthermore, when this paper conveyance system is placed near the user of the copying machine as described above, it also has the effect of significantly reducing power consumption.
