摘要： In an image reading apparatus, a white reference member for obtaining a reference value used in shading correction in the reading mechanism and an elastic member for cleaning a surface of the transparent member are provided such that respective positions of the white reference member and the elastic member with respect to the transparent member are variable. A controller controls the positions of these members with respect to the transparent member to alternately achieve movement of the white reference member to a position where the white reference member faces the transparent member and movement of the elastic member to a position where the elastic member faces the transparent member. The controller calculates the above reference value using a plurality of detection values read by the reading mechanism through the above positional control.

摘要： An image reading apparatus capable of preventing the occurrence of a streak and reading a quality image from the leading edge to the trailing edge of a original. An original is conveyed along a convey pass. The original being conveyed is guided by a guide member, at least part of the guide member being transparent. An image of the original being conveyed is read by an image sensor through the guide member. Airflow is generated, the airflow being blown into the convey pass from a location upstream in a conveying direction compared to a location of the image sensor. The guide member has a convex portion disposed at a location upstream in the conveying direction compared to the location of the image sensor.

摘要： PROBLEM TO BE SOLVED: To provide an image reading apparatus capable of removing foreign matters like paper powder or dusts from a conveying path.
SOLUTION: When a sheet-like medium P is conveyed by at least a conveying roller 10, a charging member 13 is charged, so that an electric attracting force is applied to foreign matters like paper powder or dusts on a conveying path, on which the sheet-like medium P is conveyed. Thereby, when the foreign matters like paper powder or dusts on the conveying path are conveyed to a slit 121 of a guide plate 12 by the sheet-like medium P conveyed by the conveying roller 10, they pass through the slit 121 and are adsorbed to the charging member 13. That is to say, the foreign matters like paper powder or dusts can be removed from the conveying path.

摘要： A sheet feeder has a sheet-feed opening for feeding sheets into a sheet transporting path inside the sheet feeder; a sheet-discharge opening for discharging the sheets; a sheet-holding tray which is rotatably provided and which is movable to a position where the sheet-holding tray holds the sheets and to a location where the sheet-holding tray covers the sheet-feed opening; and a discharged-sheet holding tray which is rotatably provided and which is movable to a position where the discharged-sheet holding tray holds the sheets that have been discharged from the sheet-discharge opening and to a location where the discharged-sheet holding tray covers the sheet-discharge opening. When either one of the sheet-feed opening and the sheet-discharge opening that is disposed above the other is to be covered, the sheet-holding tray or the discharged-sheet holding tray is subjected to inversion rotation so that a surface of the sheet-holding tray or the discharged-sheet holding tray that is formed opposite to a sheet-loading surface thereof forms a surface of the body of the sheet feeder and when either of the sheet-feed opening and the sheet-discharge opening is to be covered, the sheet-holding tray or the discharged-sheet holding tray is moved so that the sheet-loading surface of the sheet-holding tray or the discharged-sheet holding tray forms the surface of the body of the sheet feeder in order to cover either of the other of the sheet-feed opening and the sheet-discharge opening.

摘要： PROBLEM TO BE SOLVED: To prevent the contamination of an emission window and to facilitate the cleaning of the emission window. SOLUTION: The emission window 212 for emitting light beams is disposed on a housing of a laser exposure device having an optical element arranged inside for exposing a photoreceptor, and the upper surface of the housing is provided with a slidable shutter 216 with an opening 218. An image forming apparatus includes a guide rail not shown for movably guiding a predetermined cleaning brush 215 in the longitudinal direction of the emission window 212, independently of the laser exposure device. When the cleaning brush 215 is mounted on the guide rail and moved toward the inner side of the apparatus, the cleaning brush 215 touches a slant portion 213b of a rib and the shutter 216 is moved to the right to align the opening 218 with the emission window 212. While the cleaning brush 215 touches a longitudinally extending portion 213a, the emission window 212 is exposed to enable the cleaning of the exposed window 212 using the cleaning brush 215.
