A sheet post-processing apparatus includes a first stapler and a second stapler having different thicknesses of sheets on which a binding process can be performed. A control unit can perform a manual staple mode. If the first stapler is selected as a stapler for performing the binding process in the manual staple mode, the control unit controls the alignment member moving mechanism to move alignment members to a position defining a first insertion position for guiding the sheets to a first placing position. If the second stapler is selected, the control unit controls the alignment member moving mechanism to move the alignment members to a position defining a second insertion position for guiding the sheets to a second placing position.

A conveying device includes a first guide section, a second guide section, and an urging section. The second guide section has a guide center portion and pivots about the guide center portion. The second guide section is pivotable between a guide position and a separation position. The guide position is a position in which the second guide section is located when a conveyance path of a sheet is formed between the second guide section and the first guide section. When the second guide section is in the guide position, the urging section urges the second guide section in a first pivot direction.

A sheet feeding apparatus includes a supporting portion, a feeding portion, a regulation unit, and a sensor. The supporting portion configured to support a sheet. The feeding portion configured to feed the sheet supported by the supporting portion. The regulation unit configured to regulate a position of an edge portion of the sheet supported by the supporting portion. The sensor configured to output an output value that changes in accordance with an amount of movement of the regulation unit in the moving direction. The sensor is disposed above the supporting portion and the regulation portion in a gravity direction, and above an abutment position between the sheet supported by the supporting portion and the feeding portion in the gravity direction.

An image forming apparatus includes: a housing; an image forming unit; a conveyor; a curved guide disposed downstream of the conveyor and configured to move between a near position where the curved guide in the housing guides the sheet and a far position farther from the conveyor than the near position; and a guide member extending from the conveyor toward the curved guide and configured to guide the sheet to the curved guide when the curved guide is located at the near position. The guide member has one end portion coupled to the conveyor and the other end portion movable with respect to the curved guide. When the curved guide is moved from the near position to the far position, the other end portion is moved in a direction from a downstream end toward an upstream end of the curved guide.

A paper folding machine comprising folding mechanisms (11, 15, 24) arranged at folding positions (A-C) on a transport path (1), respectively, guides (8, 19, 20, 28, 29) positioning a paper sheet (F) relative to the folding positions by engagement with at least one side edge of the paper sheet, stoppers (12, 15, 25) stopping and positioning the paper sheet at the folding positions by bringing a leading edge of the paper sheet into contact with the stoppers, a fold misalignment detection unit (50) detecting a fold misalignment amount of the paper sheet for each folding position, and a controller (42) controlling positions of the guides and stoppers. The controller calculates, for each folding position, an average fold misalignment amount, and adjusts the position of the guide and/or stopper associated with the corresponding folding position so as to correct fold misalignment corresponding to the average fold misalignment amount.

The invention relates to a tape element dispenser system containing a container having an opening and is configured to enclose a volume. The system also contains a single elongated tape element having a width and a height where the width is at least 5 times the height. The tape element has two ends rotationally wound in a first direction into a hollow cylinder having a central axis, the hollow having two parallel annular bases perpendicular to the central axis and the single elongated element is unwound from the hollow cylinder from one of the annular bases approximately parallel to the central axis. The single elongated element has a twist in a second direction opposite to the first direction. The opening of the container comprises a main slit having a width of at least about 105% the width of the single elongated tape element.

A unit attaching detaching structure includes: a unit that is attachable to and detachable from an apparatus main body; a displacement portion that is provided on the apparatus main body and is displaceable to one side and another side; a detection unit that detects attachment of the unit when the displacement portion is displaced from the another side to the one side; a connecting portion that is separated from the detection unit in a direction intersecting with a direction of attaching/detaching of the unit, and is connected to the displacement portion so as to displace the displacement portion; a movement portion that is provided on the unit and displaces the displacement portion by moving the connecting portion when the unit is attached to the apparatus main body; and a returning unit that returns the displacement portion when the unit is detached from the apparatus main body.

An example apparatus includes a media receiving portion having a leading edge receiving region and a trailing edge receiving region for receiving media traveling onto the media receiving portion in a direction from the trailing edge receiving portion the leading edge receiving portion. The example apparatus further includes a leading edge stop coupled to the media receiving portion at the leading edge receiving portion. The leading edge stop is resiliently coupled to the media receiving portion to bias against movement of the leading edge stop from a resting position.

To correct a posture of a paper sheet inserted from various positions and angles to a normal transport state without causing any deformation due to contact with a side wall while transporting the paper sheet continuously and non-intermittently. A drive-side unit (20) includes at least one drive roller (25) that is supported rotatably about a shaft orthogonal to a normal paper-sheet transport direction and axially movably, an elastic biasing member (40) that elastically biases the drive roller in an axial direction, and a cam mechanism (50) that transmits a driving force from a driving source to the drive roller, and operates when an external force exceeding a predetermined value in a direction other than a normal transport direction is applied to the paper sheet transported by the drive roller, so as to change an axial position of the drive roller against an elastic biasing force, and a driven-side unit (100) includes a driven roller that changes a transport grip between the drive roller and a paper sheet according to a change of an axial position of the drive roller.

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.
