A printer includes a body, a cover, a long hole formed in one of the body and the cover, a first shaft provided on another one of the body and the cover and disposed to pass through the long hole, a groove formed in the one of the body and the cover, and a second shaft provided on the other one of the body and the cover and disposed to pass through the groove. The cover is attached to the body so as to be rotatable around the first shaft, the groove extends parallel to the longitudinal direction of the long hole, the cover is slidable relative to the body while the second shaft is in the groove, and the cover is rotatable around the first shaft when the second shaft is out of the groove.

In at least one embodiment of this disclosure, there is provided an image reading apparatus that includes a reader, an upstream reading conveyance rotator pair, at least one upstream conveyance rotator pair, and an upstream separator. The reader reads a detection target image on a sheet. The upstream reading conveyance rotator pair is disposed upstream from the reader in a sheet conveyance direction to convey the sheet. The upstream conveyance rotator pair is disposed upstream from the upstream reading conveyance rotator pair in the sheet conveyance direction to convey the sheet toward the upstream reading conveyance rotator pair. The upstream separator causes one rotator of the upstream conveyance rotator pair to be contacted against and separated from another rotator of the upstream conveyance rotator pair.

A conveyance apparatus includes a change conveyance unit. In a case where a first sheet in a sheet storage unit included in the feeding apparatus is fed in a landscape orientation to the conveyance apparatus, the change conveyance unit changes a conveyance orientation of the first sheet to a portrait orientation. The landscape orientation is an orientation in which a short side of the first sheet is parallel to a sheet conveyance direction of the first sheet. The portrait orientation is an orientation in which a long side of the first sheet is parallel to the sheet conveyance direction. The change conveyance unit changes the conveyance orientation of the first sheet from the landscape orientation to the portrait orientation on a substantially horizontal region between the image forming apparatus and the feeding apparatus.

A first roller pair disposed upstream of a second roller pair is separated from each other by a separating mechanism. A control portion is configured to start rotating the second roller pair after a leading edge of a sheet in a sheet conveyance direction is abutted against the second roller pair in a stopped condition. The control portion is configured to execute, based on the information concerning the sheet length acquired by the acquisition portion, either one of a plurality of modes including a first mode of rotating an upstream roller pair and the first roller pair to convey the sheet while the first roller pair is in a contact condition and a second mode of operating the separating mechanism to separate the first roller pair and of rotating the upstream roller pair to convey the sheet while the first roller pair is in a separated condition.

Provided is a binding apparatus enabling easy removal of a sheet bundle, which has been subjected to binding, from clamping teeth. The binding apparatus includes: a sheet placement portion on which sheets are placed; an alignment unit configured to align the sheets placed on the sheet placement portion; a binding member configured to bind the sheets placed on the sheet placement portion by deforming the sheets without using a staple; and a separating member configured to apply a rotational force to the sheets which are bound by the binding member to separate the sheets and the binding member from each other, the alignment unit and the separating member being constructed by different members.

A sheet processing apparatus comprises a roller disposed in a sheet conveyance path; a sheet sensor disposed in the sheet conveyance path and configured to detect conveyance of sheets and generate sensor information indicative of detection; and a controller. The controller is configured to, for each sheet of a predetermined number of sheets of a plurality of sheets conveyed by the roller, use the sensor information to generate an individual sheet-conveyance dataset indicating a sheet passage interval; and store the individual sheet-conveyance dataset in data storage. The controller is further configured to, after the roller conveys the predetermined number of sheets, calculate a summary sheet-conveyance dataset including sheet passage interval statistics for the predetermined number of sheets; store the summary sheet-conveyance dataset in the data storage; discard the individual sheet-conveyance datasets from the data storage; and evaluate the sheet passage interval statistics to determine whether to modify the predetermined number of sheets.

A sheet conveyance apparatus includes a switching member, a conveyance portion configured to convey the sheet, a driving motor configured to drive the conveyance portion, a transmission unit configured to cause the switching member to execute a pivot operation, and a control portion configured to control the driving motor and the transmission unit, wherein, in a case where the control portion conveys a first sheet in a job at a first conveyance speed by the conveyance portion and causes the switching member to execute the pivot operation, the control portion causes the switching member to execute the pivot operation at a second operating speed before the first sheet arrives at the switching member and the conveyance portion, and rotates the driving motor at a first rotational speed after the pivot operation has been executed and before the first sheet arrives at the conveyance portion.
