Abstract: A printing apparatus includes: a recording section that performs recording on a medium; a discharge tray on which the medium subjected to recording by the recording section is loaded; a detector that detects the medium loaded on the discharge tray; and an attachment section to which a sub-tray is attached, in which the detector is located at a first position and detects the medium loaded on the discharge tray in a state in which the sub-tray is not attached, is located at a second position and detects the medium in a state in which the sub-tray is attached, and moves from the first position to the second position in accordance with the sub-tray being attached to the attachment section.

Abstract: The medium detection unit is a component constituting an optical path of the detection light, and includes a first optical element disposed on an upper side of the medium transport path and a second optical element disposed on a lower side of the medium transport path so as to face the first optical element, the second optical element has a facing surface that faces the first optical element, the facing surface being located at a position that is not in contact with a medium nipped by both the first roller pair and the second roller pair, and a medium feeding direction by the first roller pair is a direction by which a leading edge of a medium fed out abuts a position upstream in the medium transport direction relative to a position where the detection light is received on the facing surface.

Abstract: A main body frame of a multifunction machine has first and second frames of which surfaces parallel to a Z-axis face each other. A recording head is disposed between the first and the second frames and fixed to the main body frame. An ejection tray is fixed to the main body frame on a +Z direction with respect to the recording head. A scanner is fixed to the main body frame on the +Z direction with respect to the ejection tray and forms an ejection space with the ejection tray. The recording head performs recording on a medium which is being transported toward a first direction, which is an in-plane direction of the first frame. The ejection tray is configured to be removed toward a second direction, which is the in-plane direction of the first frame, in a state where the scanner is fixed to the main body frame.

Abstract: A printing device includes a recording portion performing recording on a medium; a discharge tray loading the medium recorded; a first detector configured to detect the medium of a first load capacity loaded on the discharge tray; a second detector configured to detect the medium of a second load capacity smaller than the first load capacity loaded on the discharge tray; a mounting portion on which an optional device is mounted; and a controller controlling the recording by the recording portion, in which the optional device mounted on the mounting portion is positioned above the discharge tray, the first detector and the second detector are positioned below the optional device mounted on the mounting portion, and when the first detector detects the medium of the first load capacity in a non-mounted case in which the optional device is not mounted, the controller executes full load processing.

Abstract: A recording apparatus includes a recording unit, a discharge unit that discharges a medium on which recording is performed by the recording unit, and a medium receiving unit that receives a medium discharged by the discharge unit, and a medium can be fed to an optional device attached to an apparatus main body from the discharge unit. The discharge unit includes a discharge roller that discharges a medium, a forming unit that forms a medium to be discharged, and a detection unit that detects a stacking height of a medium stacked on the medium receiving unit and is located at a position where the detection unit interferes with the optional device when the optional device is attached, the detection unit and the forming unit are integrally configured, and the detection unit and the forming unit are configured to be integrally attached to and removed from the apparatus main body.
