An ejection apparatus includes a platen for supporting a recording medium, an absorber provided in the platen for absorbing liquid, an ejection unit for ejecting a plurality of types of ink including a first liquid containing a component to be deposited when the first liquid is ejected onto the absorber, and a second liquid different from the first liquid for suppressing deposition of the first liquid, a detection unit for detecting a state of a predetermined region of the absorber, and a control unit for controlling the detection unit to detect the state, and controlling the ejection unit to eject the second liquid to the predetermined region based on a result of the detection. When the first liquid is ejected to the predetermined region, the second liquid is ejected to the predetermined region after the ejection of the first liquid is finished, without using the result of the detection.

There is provided an ink-jet recording apparatus including: a transporting roller; a driven roller provided opposite the transporting roller to sandwich the recording medium between the driven roller and the transporting roller, while moving in an approaching-departing direction based on a thickness of the recording medium; a first biasing member biasing the driven roller to the transporting roller; a platen; a recording portion configured to jet ink droplets from nozzles; and a cooperative portion moving along with the movement of the driven roller in the approaching-departing direction to move the platen.

A printing apparatus for printing workpieces comprises a rotary table supporting first and second platens rotatable between a loading position located in-line between input and output lines. The transfer apparatus is operable to cyclically perform first and second movement operations, in which the rotary table rotates to move the first platen from a loading position to a printing position and vice versa. The platens may be rotatable relative to each other.

A tray for a printing apparatus including a conveying unit that conveys the tray holding a printing medium, and a printing unit that performs printing onto a print surface of the printing medium on the tray includes: a placement surface for placing thereon an adapter that holds the printing medium; a pressing member disposed on the upstream side of the adapter in the inserting direction of the tray with respect to the printing apparatus to press the adapter placed on the placement surface toward a downstream side of the inserting direction; a regulating portion configured to regulate a movement of the adapter by abutting the adapter pressed by the pressing member; and an opening into which a protrusion of the adapter is insertable.

A liquid discharging apparatus includes a transporting belt having an endless shape stretched over a plurality of rollers and configured to rotate while supporting a medium, to transport the medium in a transport direction, a liquid discharging unit configured to discharge a liquid onto the medium, and a flat plate portion for supporting the transporting belt from a side of a contact face with the roller. the flat plate portion includes an edge extending from one end of the transporting belt to the other end of the transporting belt along an extending direction intersecting the transport direction, the edge being formed by a transporting belt support face for supporting the transporting belt and a face facing upstream in a rotation direction of the transporting belt when transporting the medium in the transport direction. the edge is disposed to abut against the transporting belt along the extending direction.

Method for holding substrates on a flatbed printing system. After positioning the substrates on the substrate support surface, a leak air area not covered by the substrates is covered by positioning a flexible cover device at least over the leak air area, and preferably over the substrates as well. Thereby, air flow through the through-holes is prevented. An under-pressure is then applied to the through-holes, sucking the substrates against the substrate support surface. The flexible cover device is then withdrawn to expose the substrate for printing while the under-pressure is maintained. It was found that despite the additional amount of air passing through the through-holes uncovered by the withdrawal of the flexible cover device, the under-pressure surprisingly remained sufficient to properly hold the substrates for printing. An additional advantage is that the cover device may be applied easily and rapidly over the leak air area and substrates at once.

A platen unit includes a platen, a mount portion, and a connection portion. The platen has a surface on which a print medium is to be placed. The mount portion is mounted on a platen support portion provided in a print device. The connection portion connects the mount portion and the platen such that a position of the platen is slidable, with respect to the mount portion, between a first position and a second position in a first direction and in a second direction. The first direction is a direction along the surface of the platen. The second position is located in the first direction with respect to the first position. The second direction is a direction opposite to the first direction.
