A sheet conveyance apparatus includes a first conveyance portion configured to convey a sheet, a second conveyance portion configured to convey the sheet, the second conveyance portion including an abutment portion configured to form a loop on the sheet by being abutted against a leading edge of a sheet conveyed by the first conveyance portion, a curved guide portion, which is curved, configured to guide the sheet conveyed by the first conveyance portion to the second conveyance portion, and a rotary member arranged downstream of the first conveyance portion and upstream of the second conveyance portion in a sheet conveyance direction, and configured to be driven to rotate by a surface of the sheet that is guided by the curved guide portion, the surface sliding against the curved guide portion.

Provided is a sheet folding apparatus for folding sheets, including: a feeding-roller pair; a loop-forming space provided downstream from the feeding-roller pair, for forming a sheet loop; a pushing member for pushing the looped sheet; a folding-roller pair for nipping a prescribed part of the sheet pushed by the pushing member, thereby to fold the sheet; and a path provided between the feeding-roller pair and the folding-roller pair, for guiding the sheet fed from the feeding-roller pair toward the loop-forming space.

A sheet pressing apparatus includes an inlet port for receiving a sheet having a folding line; additional folding rollers supported by a supporting member arranged downstream from the inlet port; a lower folding guide opposing the additional folding rollers; a first drive mechanism configured to move the additional folding rollers between a pressing position, at which the additional folding rollers approach the lower folding guide to press the sheet at the folding line, and a retreat position to which the additional folding rollers are moved from the pressing position, separating from the sheet; and a second drive mechanism configured to move the additional folding rollers along the folding line. The additional folding rollers are arranged such that one end of the folding line exists between the two additional folding rollers provided at one position and the additional folding roller at the other end position is arranged on the folding line.

A sheet conveying device includes a sheet pickup body, a first sheet conveyor, and a second sheet conveyor, which are disposed in this order along a sheet conveyance direction, and circuitry. The first sheet conveyor includes a first sheet feed roller, a second sheet feed roller, and a first motor. The second sheet conveyor includes a conveyance roller and a second motor. The circuitry is configured to determine a sheet conveyance state of a sheet based on at least one of torque of the first motor of the first sheet conveyor and torque of the second motor of the second sheet conveyor. The first sheet conveyor is configured to interpose the sheet between the first sheet feed roller and the second sheet feed roller and convey the sheet to the second sheet conveyor as the first sheet feed roller rotates.

A test chart is obtained by printing a test chart image using an image forming apparatus for skew measurement of the image forming apparatus. The test chart includes a first scale image that includes a scale along a secondary scanning direction and a second scale image that includes a scale along the secondary scanning direction. The first and second scale images are arranged along a primary scanning direction. When a top-end part of the test chart is folded back, a top end of the test chart indicates different values from each other on the first and second scale images in accordance with a skew angle.

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.

A printing apparatus includes a feeding unit, a pair of rollers, a printing unit, and a control unit. The control unit can execute skew correction. The control unit can execute control to convey a preceding printing medium and a succeeding printing medium by the pair of rollers in a state in which a trailing edge portion of the preceding printing medium and a leading edge portion of the succeeding printing medium overlap. The control unit sets an execution timing of the skew correction for the succeeding printing medium based on positions of the preceding printing medium and the succeeding printing medium if a predetermined condition is met. The predetermined condition is that the preceding printing medium reaches a position at which a remaining print range for the preceding printing medium equals a predetermined print range.

A transport apparatus includes a feed unit as an example of a supply unit which supplies a medium in a transport direction, and a transport unit which transports the medium supplied from the feed unit. The transport unit includes a transport roller (a driving roller) which sends the medium, and a driven roller which nips the medium between the transport roller and the driven roller. The driven roller is movable in the transport direction relative to the transport roller.

One example embodiment in this disclosure provides an apparatus comprising an opening configured to receive a banknote into a banknote path. The apparatus also includes a plurality of inboard transport wheels positioned in the banknote path and configured to transport the banknote in a direction longitudinal to the banknote path. The apparatus also includes at least one initial transport wheel positioned in the banknote path and nearer to the opening than the plurality of inboard transport wheels, the at least one initial transport wheel configured to transport the banknote from the opening to a first of the plurality of inboard transport wheels. The at least one initial transport wheel causes the banknote to pivot around the first inboard transport wheel when a leading edge of the banknote contacts the first inboard transport wheel. Pivoting causes banknote to contact a second of the plurality of inboard transport wheels.

A first conveyance member reverses a sheet received from a first conveyance path. Second through fourth conveyance members are disposed on a second conveyance path and convey a sheet from the first conveyance member toward the first conveyance path. A restriction portion is capable of restricting driving force of a first driving source from acting on a sheet through the second conveyance member. A controller executes a first operation and a second operation. In the first operation, a second driving source stops driving the third and fourth conveyance members while a first sheet is being nipped at the fourth conveyance member, and a second sheet is conveyed to be abutted with the third conveyance member. In the second operation, the second driving source starts driving the third and fourth conveyance members while the restriction portion restricts driving force of the first driving source from acting on the second sheet.
