A medium receiving tray has a first tray and a second tray. A movable support having a second support surface for supporting media is disposed in the second tray. When the medium receiving tray is in a first state, the movable support is positioned above a first support surface of the first tray. When the medium receiving tray is switched from the first state to a second state, a free end is detached from the downstream end of the first support surface and displaced downward, and the second support surface is thereby inclined upward toward the downstream in a medium discharging direction.

A recording apparatus includes a recording section configured to perform recording onto a medium, a facing section facing a recording surface of a medium at a discharge position where the medium recorded by the recording section is discharged, and a light emitter configured to emit light toward the recording surface. The facing section includes an optical member disposed at a position where the light emitted by the light emitter enters, the optical member being configured to pass the incident light toward at least the recording surface.

A medium conveying apparatus includes a medium tray, a pair of side guides to regulate a width direction of a medium, and a housing on which the medium tray is located and including a conveyance path capable of conveying the medium placed on the medium tray. The pair of side guides are located on the medium tray so that outer ends of the pair of side guides can be positioned from an inside of the medium tray to an outside of a maximum width of the medium tray. The conveyance path can convey a medium having a width of an inside of the pair of side guides even when the outer ends of the pair of side guides are positioned outside the maximum width of the medium tray.

A medium ejecting apparatus includes a housing including an ejection port to eject a medium, a tray provided below the ejection port, to load the medium ejected from the ejection port, and a medium regulating member accommodated in the housing so as to be drawn out. The medium regulating member includes a medium contacting portion capable of regulating a position of a front end of the medium on the tray in a medium ejecting direction, a first supporting portion to support the medium contacting portion, and a second supporting portion to swingably support the first supporting portion.

In order to provide a sheet stacking apparatus for maintaining alignment characteristics of long-length sheets, the sheet stacking apparatus is a sheet stacking apparatus located above in a pair of sheet stacking apparatuses provided to overlap vertically along a vertical direction, and is provided with a first stacking section for stacking sheets, a second stacking section provided to extend from a downstream end of the first stacking section in a sheet transport direction and connected to the first stacking section rotatably, and a third stacking section which is attached to the second stacking section to extend from a downstream end of the second stacking section in the sheet transport direction, includes an inclined angle with respect to a horizontal surface smaller than in the second placing face, and which is attachable and detachable with respect to the second stacking section in a rotation direction.

A sheet aligning device includes a support member, a regulation member, a regulation member moving mechanism, and an alignment member. The support member supports leading ends of sheets. The regulation member is connected to the support member and is provided to face an inclined tray in such a way as to define a sheet entry space in which the leading ends of the sheets enter. The regulation member moving mechanism is configured to, each time a sheet is conveyed onto the inclined tray, move the regulation member in a separating direction to widen the sheet entry space, and then in an approaching direction to narrow the sheet entry space. The alignment member aligns the sheets by abutting on rear ends of the sheets.

A recording apparatus includes: an apparatus main body that includes a recording unit; a medium-receiving tray that is configured to be switched between a first state and a second state; and a motor, in which the medium-receiving tray includes a first tray, a second tray that is configured to be displaced with respect to the first tray and that is positioned further than the first tray from the apparatus main body when the medium-receiving tray is in the second state, a pinion gear engaged with a first rack formed in the first tray in a displacement direction of the second tray and with a second rack formed in the second tray in the displacement direction, and a displacement section that supports the pinion gear and that is displaced in the displacement direction in response to receiving power from the motor.

An example stacking system comprises a stacking member movable between a first position in which the stacking member is configured to partially support a first stack of printed substrates, and a second position in which the stacking member is disengaged from the first stack. A receptacle positioned below the stacking member is configured to hold a second stack of printed substrates. A controller is configured to cause the stacking member to move between the first position and the second position when the first stack satisfies a criterion, thereby depositing the first stack into the receptacle on top of the second stack.
