摘要： An image reading apparatus includes a reading glass, a second guide member, and a control section. The reading glass and the second guide member together form a document feed path. The second guide member includes a white reference plate. The control section performs, when it is determined that shading correction image data is affected by a stain, a stain location determination of whether the stain is attached to the reading glass or the second guide member according to a tone value variation in the portion of the shading correction image data that corresponds to the stain edge, the variation being along a predetermined distance in the main scanning direction.

摘要： A document reader includes an exterior panel covering a region of a document feed path including a second image read position from outside. The document reader also includes a first open/close member forming a region of the exterior panel including a portion opposed to the image read position. The document reader further includes a second open/close member positioned inwardly of the first open/close member to define a region of the document feed path including the image read position. The first and second open/close members are supported at respective different fulcrums for opening/closing movement about respective shafts extending perpendicularly to the document feed direction, thereby shielding the second image read position from extraneous light.

摘要： This image forming apparatus has an image forming unit which is composed of a toner supplying section and a printing section. The printing section includes: an opposing electrode which has a flat part arranged in parallel with the peripheral surface of a toner support; a high-voltage power source for applying a high voltage to the opposing electrode; a control electrode provided between the toner support and opposing electrode; and a cleaning brush. A paper suction portion includes fans as decompressing means and a chamber with a multiple number of suction ports disposed therein, through which air is sucked so that the sheet will not be in contact with the control electrode. Further, a multiple number of grooves are formed in parallel with the sheet conveying direction on the downstream side of the sheet conveying means with respect the sheet conveying direction. These grooves reduce the contact area between the sheet and the support surface and hence reduce the frictional resistance, thus achieving a smooth paper conveying operation.

摘要： A document feeding device of the present invention includes: a discharge roller pair that includes a first drive roller and a first idler roller; and a transport roller pair that includes a second drive roller and a second idler roller. Either one of the second drive roller and the second idler roller moves between a contact position where said roller is in contact with the other roller and a separation position where said roller is separated from the other roller. The transport roller pair is disposed on the other side of the discharge roller pair from a discharge tray. The transport roller pair transports a document that has passed through the reading position to the discharge roller pair by positioning said roller at the contact position in a case where the first drive roller rotates forward.

摘要： A sheet carrying apparatus, being applicable in (i) an automatic document feeding apparatus and/or (ii) paper feeding and conveying mechanism of an image forming apparatus, has an opening in that part of a curved guiding surface of a lower conveyance guide of a sheet conveyance guiding section constituting a curved conveyance path, which receives a front end of a document fed to the curved conveyance path. The opening has such a size in a guide width direction orthogonal to a document conveying direction, which is passable for a small size sheet not larger than a predetermined size. With this, the small size sheet passed through the opening is sorted out.
