摘要： A printer includes a guide frame, a deforming section, and a lever member. The guide frame includes a transport path. The deforming section includes a toothed roller, a supporting holder, and a torsion spring and deforms paper. The toothed roller comes into contact with the paper discharged from the transport path. The supporting holder is configured to pivot between a first position at which the toothed roller is located on the transport path and a second position at which the toothed roller is not located on the transport path. The torsion spring presses the supporting holder from the second position to the first position. The lever member is configured to switch between a regulating state in which pivoting of the supporting holder at the first position or the second position is regulated and a non-regulating state in which pivoting of the supporting holder is not regulated.

摘要： A paper ejection device includes: an ejection portion that ejects sheets of paper; a housing portion that houses the ejected sheets of paper in a sequentially stacked state; and a guiding portion that guides the sheets of paper, before being ejected, to the ejection portion while curving the sheets of paper. The housing portion is adjustable to plural angles including at least an angle at which the ejected sheets of paper are housed while being curved in a direction opposite to a direction in which the sheets of paper have been curved by the guiding portion.

摘要： A decurling device includes: a first transport unit including a transport roller, the first transport unit that sandwiches a transported sheet and transports the transported sheet further downstream; and a second transport unit including an endless belt that is in contact with the transport roller. The transport roller has an elasticity that, when the belt is pressed against the transport roller, allows the belt to bite into the transport roller by a bite amount corresponding to a pressing force, the second transport unit includes an abutting member disposed inside the belt, the abutting member pressing the belt from an inside of the belt and causing the belt to abut against the transport roller, and a guide member, the abutting member includes an upstream protrusion, an downstream protrusion, the upstream protrusion and the downstream protrusion being provided at positions away from each other at an upstream portion and a downstream portion in a sheet transport direction, each of the upstream protrusion and the downstream protrusion protruding toward an inner surface of the belt, and a recess provided in an intermediate portion between the upstream protrusion and the downstream protrusion in the sheet transport direction, the recess being recessed away from a straight line connecting a top portion of the upstream protrusion and a top portion of the downstream protrusion, the guide member includes a contact surface that is in contact with the inner surface of the belt, the contact surface defining a part of a circulation track of the belt, and the upstream protrusion protrudes beyond a virtual circle that is tangent to the contact surface.

摘要： A sheet discharging apparatus includes a first detecting portion provided in an apparatus body and configured to detect a move of a movable member in a state where a movable tray is at an upper limit position in a moving direction of the movable tray, wherein a detection result of the first detecting portion changes depending on a position of the movable tray in the moving direction. In addition, a second detecting portion detects the position of the movable tray in the moving direction, and a control portion, in a case where the second detecting portion detects that the movable tray is at the upper limit position, determines whether a sheet is present on the movable tray based on the detection result of the first detecting portion. When the second detecting portion does not detect that the movable tray is at the upper limit position, the control portion determines that a sheet is present on the movable tray regardless of the detection result of the first detecting portion.

摘要： An apparatus for controlling cross curl in corners of sheets between in-line transports includes a curved baffle placed between the two transports. A thin layer of high velocity air is applied to the curved baffle only at lead edge corner regions of the sheets. The high velocity air layer, which will have a tendency to follow the curved baffle (Coanda effect), will divert corners of the sheets (Bernoulli effect) towards the curved baffle. By positioning a curved baffle between the two transports and by applying a uniform air stream to it, a lower pressure area will be created. This will flatten the corners of the sheets and ensure passage between downstream baffles and acquisition by a downstream transport.
