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 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. Applying of the sheet carrying apparatus in such apparatuses (i) and/or (ii) does not need any increase in cost or any increase in an apparatus size to bring about an effect that a document (business card, ID card) and/or recording sheet smaller than a normal document can be fed to a different conveyance path so as to be delivered to a different delivery tray.
