Abstract (en)

[origin: EP1905710A2] A sheet conveying device (3) includes a belt (8) having a plurality of throughholes (10), a fan (11) disposed so as to interpose a portion of the belt placed in a return run position (8b) between the fan and a portion of the belt placed in the forward run position (8a), and a case (12) that defines a chamber (20) with a portion of the belt placed in the forward run position. The fan (11) creates a negative pressure within the chamber (20) by drawing air through the throughholes of the endless belt, thereby removing dust and other unwanted particles and debris from the endless belt. In one or more examples, a brush (14) may also be included to provide further removal of unwanted dust and particles. Further, in one or more configurations, the sheet conveying device may also include belt rollers (6,7) and/or supporting members (9).
