Patent attributes
A sheet feeder with electrostatic dust-collecting function includes a paper path, a feeding roller, a dust-collecting passageway, an electrostatic charge generator and a dust-collecting box. The feeding roller located on the paper path feeds a sheet through the paper path. The dust-collecting passageway has an inlet connected to the paper path and an outlet located opposite to the inlet. The electrostatic charge generator disposed at the outlet of the dust-collecting passageway generates electrostatic charges to attract dust coming from the sheet through the dust-collecting passageway and the paper path. The dust-collecting box for collecting the dust is disposed at the outlet of the dust-collecting passageway and has an adhesive layer for adhering the dust.
