A slider moving in a sliding direction between first and second positions shifts a second path-defining member, relative to a first path-defining member, between first and second states. A pair of movable members each disposed on a corresponding side of a slider in a width direction is movable individually in the sliding direction to shift between third and fourth states. The movable members, when both in the third state, position the slider to the first position and, when both in the fourth state, position the slider to the second position. Each movable member supports a corresponding widthwise end of the slider immovably in the sliding direction and movably in the width direction. A support frame supporting the second path-defining member supports a widthwise central portion of the slider movably in the sliding direction and rotatably on a plane parallel to the sliding direction and the width direction.

An image forming apparatus, comprising: a housing having a sheet discharge tray, a first opening, and a second opening disposed on an upper side of the first opening; an image forming unit; a sheet discharge path communicating with the first opening; a re-conveying path communicating with the second opening; and a swinging member having a first surface facing the first opening and a second surface, wherein the swinging member has a first end area swingably supported by the housing, a second end area, and a rib; the swinging member is disposed to be movable between a first position and a second position at which the second end area gets higher; and the rib is formed on the second surface opposing the first surface facing the sheet discharge tray in a state where the swinging member is disposed at the second position.

The object of the present invention is to propose a novel device and a novel method to allow the transportation of printable substrates precisely, suited to substrates of various types, sizes and thicknesses. Furthermore, the invention is suited to printing machines that involve no contact with the substrate, such as inkjet printing machines.

A printing device includes a first ejector that ejects a recording medium to an exterior, a second ejector that enhances a rigidity of the recording medium more than by the first ejector, and ejects the recording medium to the exterior, and an ejector selector that selects either the first ejector or the second ejector.

A sheet conveying apparatus includes: a first pair of conveying rollers for conveying a sheet; a second pair of conveying rollers against which the leading edge of the sheet conveyed by the first pair of conveying rollers is hit and which conveys the sheet together with the first pair of conveying rollers by rotating after a loop is formed on the sheet; a separating portion for separating the first pair of conveying rollers; a first conveyance path for guiding the sheet; a second conveyance path which is a path different from the first conveyance path and guides the sheet; and a controller which changes a separation timing at which the first pair of conveying rollers is separated after the loop is formed on the sheet, depending on whether the sheet is guided by the first conveyance path or by the second conveyance path.

A medium transport apparatus includes a body portion, an inversion unit, and an extension unit. The body portion has a second manual feed path for a sheet material. The inversion unit is configured to be mounted on and separated from the body portion, covers the second manual feed path when the attachment/detachment portion is mounted the body portion, and exposes a portion of the second manual feed path when the attachment/detachment portion is separated from the body portion. The extension unit is configured to be attached to and detached from the attachment/detachment portion. The extension unit extends, in a state in which the inversion unit is separated, the second manual feed path in a transport direction of the sheet material by being detached from the inversion unit and attached to the body portion.

A printing apparatus includes a print section configured to perform printing on a first side of a medium and then perform printing on a second side that is a back side of the first side, a supply path configured to supply the medium toward the print section, a feeding roller configured to feed the medium along the supply path from an upstream side to a downstream side in a transport direction, a toothed roller provided on the downstream side of the feeding rollers in the transport direction, a drive source configured to rotate the feeding roller and the toothed roller, and a controller configured to control driving of the drive source. The controller performs rotation control for rotating the feed rollers prior to the rotation of the toothed roller with which the medium has collided.
