A post-processing device includes an intermediate tray on which a medium transported in a transport direction is placed, a discharge port through which the medium post-processed on the intermediate tray is discharged, a discharge tray which is disposed in a gravity direction with respect to the discharge port and on which the medium discharged from the discharge port is placed, and an elevating mechanism which elevates the discharge tray, in which the elevating mechanism can move the discharge tray to a first normal position and a first standby position positioned in a direction opposite to the gravity direction with respect to the first normal position, and moves the discharge tray to the first normal position or the first standby position according to an amount of ink before the medium comes in contact with the discharge tray or the medium previously placed on the discharge tray.

A paper discharge apparatus includes a discharge port through which paper is discharged, a transport unit that transports the paper to the discharge port, a sensor disposed adjacent to the discharge port, and a controller. The controller is configured to control the transport unit such that a downstream side end of the paper is exposed through the discharge port, determine based on an output from the sensor whether or not the downstream side end of the paper is being pulled, and control the transport unit so as to change a transport mode of the paper according to a determination of whether or not the downstream end of the paper is being pulled.

Provided is a printing apparatus enabling a user to easily perform jam processing. The printing apparatus includes a printing unit, a cassette in which a plurality of sheets to be printed by the printing unit are mounted, and which is capable of being drawn out from the device by a user, a roller pair which is capable of being in an abutting state and a separate state and transports the sheet supplied from the cassette by interposing the sheet, in the abutting state, and a mechanism which changes the roller pair from the abutting state to the separate state as the cassette is drawn out.

A document managing method for a printing device is provided. The document managing method includes the following steps. Firstly, a printing mechanism prints a document with plural papers, and transfers the plural papers to a paper collection platform. Then, a management module manages the plural papers from two lateral sides of the plural papers. Then, a paper ejection module ejects a first portion of the plural papers at a first speed, and then ejects a second portion of the plural papers at a second speed. Consequently, the plural papers are exited from the paper collection platform. Then, the management module is separated from the two lateral sides of the plural papers, so that the plural papers fall down to a supporting tray. The first speed is faster than the second speed.

A medium-discharging device includes: a device main body including a medium-discharging section that discharges a medium; a medium-receiving tray that receives the medium discharged by the medium-discharging section; and a pressing member that is configured to be attached to and detached from to the device main body and presses the medium discharged by the medium-discharging section against the medium-receiving tray in a state in which the pressing member is attached to the device main body, in which the pressing member is configured to switch, in the state in which the pressing member is attached to the device main body, between a first state in which the pressing member comes into contact with the medium-receiving tray and a second state in which the pressing member retreats upward so as to be apart from the medium-receiving tray.

A printer includes a printing unit, a casing, a scanner unit disposed in an upper portion of the casing, and a discharge unit that, below the scanner unit, is connected to the casing pivotably between a closed position and an open position and that a sheet of paper is discharged to. The discharge unit includes a placement surface for the sheet and a medium support unit capable of supporting the sheet from below while in a state of being protruded from the placement surface. The medium support unit is displaceable between a maximum protruded position and a minimum protruded position. When the amount of protrusion of the medium support unit from the placement surface when the discharge unit is in the open position is less than the amount of protrusion of the medium support unit in the maximum protruded position from the placement surface.

An upper supply tray is mounted at an upper mount position in a housing. A lower supply tray is mounted at a lower mount position lower than the upper mount position in the housing. A first print engine records an image on a sheet conveyed from the upper supply tray. A second print engine records an image on a sheet conveyed from the lower supply tray. A lower discharge tray supports the sheet on which the image is recorded by the first print engine. An upper discharge tray supports the sheet on which the image is recorded by the second print engine. The upper discharge tray is located at a higher position than the lower discharge tray. A first display displays at least: a first correspondence between the lower discharge tray and the upper supply tray; or a second correspondence between the upper discharge tray and the lower supply tray.

A medium processing apparatus includes a printer, a supporting member having a sheet-like shape and configured to support a discharged medium, and a winding unit configured to wind the supporting member and move with respect to the printer. The winding unit has a first case and a second case that rotatably support a winding shaft, and a placement portion placed at a flat surface. The first case and the second case in a state where axis lines of respective bearing portions that support the winding shaft are aligned with each other and in a state of being held so as to be mutually non-rotatable in a plane orthogonal to an axis line of the winding shaft, and when the winding unit is installed on a flat surface, the placement portion contacts the flat surface.

A post-processing device includes an intermediate tray on which a medium transported in a transport direction is placed, a discharge port through which the medium post-processed on the intermediate tray is discharged, a discharge tray which is disposed in a gravity direction with respect to the discharge port and on which the medium discharged from the discharge port is placed, and an elevating mechanism which elevates the discharge tray, in which the elevating mechanism can move the discharge tray to a first normal position and a first standby position positioned in a direction opposite to the gravity direction with respect to the first normal position, and moves the discharge tray to the first normal position or the first standby position according to an amount of ink before the medium comes in contact with the discharge tray or the medium previously placed on the discharge tray.

An image forming apparatus includes an output unit to which a recording medium on which an image has been formed is output, the output unit including an output unit body, and an extension portion that is disposed on the output unit body so as to be extendable from the output unit body in an output direction of the recording medium, the extension portion including a handle portion that is recessed in a direction away from a back surface of the recording sheet so as allow a finger to be hooked in a direction in which the extension portion is extended in the output direction of the recording medium, the back surface being a surface that is in contact with the output unit body, and a protrusion that protrudes toward the back surface of the recording medium from the extension portion.
