A sheet conveying apparatus capable of continuing conveyance of sheets without causing a jam even when a switching member performs an operation for switching a conveyance path again. A switching member is disposed at a branching point of a conveyance path through which the sheet is conveyed by a conveying unit, and is operated by a drive unit for witching a destination of conveyance of the sheet. A controller causes the drive unit to operate the switching member, and performs a checking operation for checking a state of the drive unit based on an output from a sensor that detects a state of the switching member. The controller controls a sheet conveyance interval between a first sheet conveyed by the conveying unit and a second sheet conveyed following the first sheet, according to a result of the checking operation.

A document conveyance apparatus includes a document conveyance section, a cover, an opening and closing detection sensor, a document detection sensor, and a control section. The control section detects opening and closing of the cover on the basis of an output value of the opening and closing detection sensor and detects whether or not there is a document in a predetermined detection position on the basis of the output value of the document detection sensor. If, when the output value of the document detection sensor has changed from a value indicating an opened state of the cover to a value indicating a closed state thereof, the output value of the document detection sensor is a value indicating that there is the document, the control section detects a half-closed state where the cover is not completely closed.

A document conveyance apparatus includes a loading portion having a loading surface for a document, a rotating member, a detection unit, a feeding roller, and a support portion. The rotating member includes a front end portion protruding from the loading surface and rotates about a rotary shaft by being in contact with the loaded document. The detection unit detects rotation of the rotating member and detects presence or absence of the loaded document. The feeding roller feeds the document by being in contact with the document loaded on the loading surface. The support portion rotatably supports the rotary shaft. When the rotary shaft is viewed from an axial direction, the rotary shaft includes a recessed portion recessed from an outer periphery section of the rotary shaft toward a shaft center of the rotary shaft. The support portion is in contact with the recessed portion to rotatably support the rotating member.

A sheet feeding apparatus includes an apparatus body, an opening/closing member openable/closable with respect to the apparatus body and including a support portion supporting a sheet in a condition in which the opening/closing member is opened. The sheet supported by the support portion is fed by a feed portion. The opening/closing member is provided with a detection portion configured to detect the sheet on the support portion. The detection portion is disposed at a position where the detection wave emitted from the detection portion is not detected in a condition in which the opening/closing member is closed.

A sheet conveying device, which is incorporated in an image forming apparatus, includes a first detector to detect an angle deviation of a recording medium to a sheet conveying direction, a second detector to detect a lateral shift of the recording medium to a width direction, a third detector to detect at least one of the angle deviation and the lateral shift after correction of the angle deviation detected by the first detector and the lateral shift detected by the second detector, and a rotary body to perform a primary movement by (1) rotating in the sheet conveying direction and returning to a reference position and by (2) moving in the width direction and returning to the reference position, and a secondary movement by performing at least one of (1) and (2) after the primary movement.
