An image processing apparatus according to the present invention has: an apparatus main body whose external appearance is configured from an upper casing, a lower casing, and a link casing that vertically links the upper casing and the lower casing and that has a paper discharge opening for discharging paper on one side face; a paper discharge portion that is formed as a space between the upper casing and the lower casing and that is to store paper discharged from the paper discharge opening; and an operation panel portion that is disposed in a vertically tiltable manner on a front face of the upper casing. When viewing the apparatus main body from the front side, an open space that allows paper discharged to the paper discharge portion to be viewed is provided between the operation panel portion and the link casing.

A medium discharging device includes a first tray, a second tray receiving a medium from the first tray, a supporter which is configured to be displaced from a retreat position in the first tray and an advance position above the second tray and which supports the medium, an aligner which is provided in the supporter and that aligns a first end portion which is an upstream end portion in a discharge direction of the medium supported by the supporter, to be displaced together with the supporter, and a restrictor configured to be displaced between a restriction position where an upstream movement of the first end portion of the medium in a position of the aligner in the discharge direction and a non-restriction position where the movement is not restricted, when the supporter is in the advance position.

A sheet processing apparatus includes a first and second alignment members that moves relatively in a width direction to align a position of a sheet in the width direction. Each alignment member includes a contact surface configured to come in contact with an end of the sheet in the width direction, a lower portion configured to support a lower surface of the sheet, and an upper portion facing an upper surface of the sheet. For each of the first and second alignment members, the lower portion is more distant from the contact surface than the upper portion in the width direction, the lower portion is positioned above a lower end of the contact surface in a gravity direction, and a distance between the upper portion and the lower portion in the gravity direction is smaller than a length of the contact surface in the gravity direction.

A printing system executes printing of a plurality of copies of a document, and includes first and second paper eject trays. The printing system ejects a plurality of paper sheets of the document to the first or second paper eject tray; detects a full state or a near full state being a predetermined number of paper sheets less than the full state; and ejects the paper sheets of a next copy to the first paper eject tray until the first paper eject tray is full and subsequently to the second paper eject tray, in response to detecting that a total ejectable paper sheet number is greater than or equal to the number of paper sheets of the next copy, the total ejectable paper sheet number being obtained by adding together the numbers of paper sheets that can be ejected to the first and second paper eject trays.
