An image forming apparatus includes: a pair of first rollers configured to nip a paper sheet in a reference position and convey the paper sheet, the pair of first rollers being pressed against each other; and a control unit configured to control operation of the pair of first rollers to correct a positional deviation in a width direction of the paper sheet, by moving the pair of first rollers from the reference position in the width direction perpendicular to a direction of conveyance of the paper sheet, wherein, the control unit controls the operation of the pair of rollers, to complete a series of operations for the pair of rollers to separate from each other, to return to the reference position, and to be again pressed against each other, before a bottom edge of the paper sheet nipped by the pair of rollers passes through the pair of rollers.

An object of the present invention is to correct the deviation of a sheet in the width direction occurring on a conveyance path from a sheet correction mechanism (4) to a discharge tray. A sheet shift portion (41, 43, 44) moves a sheet in the width direction. A conveying position detecting portion (45, 46, 47) detects the position of the sheet in the width direction. A discharge position detecting portion (54, 8a) detects a discharge position of the sheet, in the width direction, discharged onto a discharge tray (33) in a sheet discharge portion (31). A control portion (8b) derives an amount of deviation between the discharge position and a discharge reference position based on a detection result of the discharge position detecting portion (54, 8a). Furthermore, the control portion (8b) corrects a conveying position of the sheet in a sheet conveying portion according to the amount of deviation.

Systems and methods for deskewing a media object may include receiving, at a deskew of a self-service terminal, the media object. The method may also include engaging a drive member to position the media object into a first position within the deskew. A deskew member may be engaged in a first direction to position the media object into a second position within the deskew. The deskew member may be engaged in a second direction to position the media object into a third position within the deskew.

An image forming apparatus includes an apparatus body, a sheet container, an image forming part to form an image, a sheet feeding rotary body to feed the recording medium, a sheet separating rotary body to contact the sheet feeding rotary body and rotate with the sheet feeding rotary body with a sheet separation nip region formed therebetween, a rotation adjusting unit to adjust rotation of the sheet separating rotary body, a sheet containing unit to contain the recording media therein, a sheet separating body storing unit disposed at one end of the sheet containing unit to store the sheet separating body therein, and a load resistance applying mechanism to apply a rotational load resistance different from a contact force generated by contacting of the sheet separating rotary body with the sheet feeding rotary body, to the sheet feeding rotary body with no rotation driving force applied thereto.

A sheet feeding apparatus includes a conveyance guide member provided in an apparatus body and having a reference plane against which a sheet widthwise side edge orthogonal to a sheet feeding direction abuts. The reference plane is provided upstream in the feed direction of a downstream end in the feed direction of the sheet stacked on the stacking member in a state in which the sheet feed cassette is attached to the attachment position of the apparatus body and is provided under, in terms of a vertical direction, an uppermost sheet stacked on the stacking member in the state in which the sheet feed cassette is attached to the attachment position of the apparatus body.

A paper medium recognition device according to one embodiment of the present invention includes: a main body that provides a transportation path in which an alignment reference line for aligning a paper medium is arranged on one side; and an alignment unit which has a transportation roller which transports the paper medium in the longitudinal direction along the transportation path, and which has an alignment roller that is arranged in the direction orthogonal to the transportation roller so as to transport the paper medium in the width direction toward the alignment reference line. A phase difference is provided during the rotation of the transportation roller and the alignment roller, and thus the paper medium can be alternately transported in the longitudinal direction and width direction.

The sheet conveyance apparatus includes first and second rollers, the second roller coming into contact with the first roller and thereby forming a nip portion, the second rotation axis being inclined with respect to the first rotation axis, wherein the second roller includes a first outer circumferential portion having a first outside diameter, a second outer circumferential portion arranged on one side of the first outer circumferential portion in an axial direction of the second rotation axis and having a second outside diameter larger than the first outside diameter, and a third outer circumferential portion arranged on the other side of the first outer circumferential portion, and wherein an outer circumferential surface of the first roller contacts with at least the first, second and third outer circumferential portions of the second roller, to form the nip portion.

An image forming apparatus includes: a pair of rollers for conveying paper; a rocking mechanism for rocking the pair of rollers in a second direction orthogonal to a first direction., the first direction being a paper conveying direction; an upstream pair of rollers provided upstream of the pair of rollers in the paper conveying direction for conveying the paper; an upstream rocking mechanism corresponding to the upstream pair of rollers for rocking the upstream pair of rollers in the second direction; a first paper detector for detecting an end position of the paper in the second direction; and a controller controlling the rocking mechanism based on the paper end position to effect first rocking correction in which the pair of rollers is rocked, wherein the controller controls the upstream rocking mechanism to effect second rocking correction in which only the upstream pair of rollers is rocked.
