Abstract: In a printer, a scanner unit is formed into a taper shape having a thinner thickness on a side of a pick-up roller in a removing direction of a process unit, to allow the process unit to be removed from the printer. A part of a sheet feeding path is formed in an area between the process unit and a sheet cassette. An image forming position on the sheet feed path is set lower than an upper end of the pick-up roller. Thus, removal of the process unit can be readily performed. Further, the height of the printer at a position of the pick-up roller can be reduced as compared with a case where the scanner unit is not formed into a taper shape.

Abstract: A sheet processing apparatus operating in xerographic printing apparatus employs a single-component magnetic toner. The inventive features of the sheet processing apparatus are directed toward smooth transportation and discharge of printing sheets sent through the printing apparatus, across a sheet transport guide, and through an image fixing and sheet transporting unit which finally discharges the printing sheets. Conductivity of the transport guide is selected by the material of which it is made, specified herein to have superficial resistivity in the range of ten thousand to one hundred million megohms. Charge applied to a printing sheet to electrostatically attract the magnetic toner during the xerographic printing is thus drained by the transport guide gradually enough not to disturb the adhesion of the toner to the sheet, yet rapidly enough to prevent the sheet from being curled upward by electrostatic attraction toward a residual toner container just over the downstream end of the guide, in the optimally compacted arrangement of the various components of the sheet processing and xerographic printing apparatus into a facsimile machine or the like.

Abstract: A sheet conveying device conveys sheets by using a suction conveyor belt having small holes. The lowermost sheet stacked on a sheet table is conveyed while being adsorbed on the conveyer belt. A suction fan sucks the lowermost sheet by way of an air suction port formed in a suction duct and the small holes. Sucked air is introduced into an air nozzle through a guide duct. Air blown off from the air nozzle raises the second sheet from the lowermost sheet and the subsequent sheets, to separate the sheets from the lowermost sheet. The suction duct is provided with an auxiliary suction port for ensuring the amount of air blown off from the air nozzle.
