Abstract: The document conveying apparatus includes a body, a document tray, a guiding tray, a first support member that supports the document tray movably between a open position where a document is placed on the first document stacking face, and a close position where the document tray is closed, and a second support member that supports the guiding tray. The second support member positions the guiding tray at a first distance from the document tray, when the document tray is at the open position. The second support member positions the guiding tray at a second distance from the document tray, when the document tray is at the close position. The second distance is smaller than the first distance.

Abstract: A sheet feeding apparatus includes a disengagement mechanism to disengage a rotary feeding member and a separation member to be apart from each other, a pressing portion to press an upper face of a sheet supported on a sheet supporting portion, and a detector to detect displacement of the sheet pressed by the pressing portion. A controller executes one mode among a plurality of modes to feed the sheet supported on the sheet supporting portion based on a detection result of the detector. In a first feed mode, a leading edge of the sheet passes a position of a separation portion with the rotary feeding member and the separation member disengaged by the disengagement mechanism. In a second feed mode, the leading edge of the sheet passes the separation portion with the rotary feeding member and the separation member engaged.

Abstract: A sheet conveying apparatus includes first, second, and third rotating members, a switching unit, and a regulating member. The first rotating member rotates in one direction to convey, with the second rotating member, a sheet in a first direction and convey, with the third rotating member, the sheet in a second direction different from the first direction. The switching unit switches the first rotating member between first and second positions. The first position is a position in which the first rotating member coveys a sheet with the second or third rotating member. The second position is a position to which the first rotating member is retracted from the first position. Where the first rotating member moves from the first position, the regulating member regulates the sheet position so that a sheet rear end held by the second and third rotating members is positioned above a first rotating member moving trajectory.
