A medium-transport apparatus includes: an apparatus main body having the transport path for transporting the medium; and a cover CV provided on the side surface of the apparatus main body and configured to be switched between a first state of exposing the transport path and a second state of covering the transport path. The cover CV is divided into: a first cover that has the rotation shaft along a Z-axis and is rotatable with respect to the apparatus main body; and a second cover that is arranged on a −Z side of the first cover, has the rotation shaft along a Y-axis on the Z-side, and is rotatable with respect to the apparatus main body.

Medium-transport apparatus and medium-transport system

A recording system includes a transportation unit that transports a paper sheet, an ejection unit that ejects an ink, a heating unit that heats the paper sheet, a discharge unit to which the paper sheet is discharged, and a control unit. The control unit specifies an amount of ejection of the ink from the ejection unit. The control unit also controls an operation of the heating unit such that an undried region where the ink on the paper sheet is not dried and a dried region where the ink on the paper sheet is dried are formed on the paper sheet. Then, the control unit controls a transporting operation by the transportation unit such that the paper sheet on which the dried region and the undried region are formed is discharged to the discharge unit.

A medium-transport apparatus includes: an apparatus main body having the transport path for transporting the medium; and a cover CV provided on the side surface of the apparatus main body and configured to be switched between a first state of exposing the transport path and a second state of covering the transport path. The cover CV is divided into: a first cover that has the rotation shaft along a Z-axis and is rotatable with respect to the apparatus main body; and a second cover that is arranged on a &#x2212;Z side of the first cover, has the rotation shaft along a Y-axis on the Z&#x2212; side, and is rotatable with respect to the apparatus main body.

A liquid ejecting unit includes: a first chamber; a second chamber; a third chamber; a fourth chamber; a first liquid passage for supplying a first type of liquid to the first chamber and the third chamber; a second liquid passage for supplying a second type of liquid to the second chamber and the fourth chamber, the second type of liquid differing from the first type of liquid; a first fluid passage for supplying fluid to the first chamber and the second chamber; and a second fluid passage for supplying the fluid to the third chamber and the fourth chamber.

Liquid ejecting unit and liquid ejecting apparatus

A liquid ejecting head includes a plurality of driving elements that causes an ejection of a liquid from a nozzle by causing a fluctuation in a pressure, a sealing body that seals a first space for accommodating the plurality of driving elements, a case member that forms a second space for surrounding the sealing body, an atmosphere vent that is formed in the case member and through which the second space communicates with the air, a communication hole that is formed in the sealing body and through which the first space communicates with the second space, and a moisture absorbent disposed in the second space.

Liquid ejecting head and liquid ejecting apparatus

A liquid ejecting head includes head units each of which includes a corresponding head substrate and ejects liquid, flexible cables each of which has one end connected to the corresponding head substrate, and a common member including the head units that are fixed thereto. In the liquid ejecting head, when a first direction, a second direction, and a third direction are directions that orthogonally intersect each other and the common member is placed on a virtual surface defined by the first direction and the second direction and has a thickness extending in the third direction, the common member extends more in the first direction than in the second direction. In addition, a fixation region in which each of the flexible cables and the corresponding head substrate are fixed to each other extends more in the second direction than in the first direction when viewed in the third direction.

A liquid discharge apparatus including a liquid discharge head that discharges a liquid by vibrating a vibration plate by a drive element and changing a pressure in an internal space filled with the liquid, a pressurization supply unit that forcibly feeds the liquid into the liquid discharge head, and a controller that restricts drive of the drive element in accordance with a pressure condition in the liquid discharge head.

Liquid discharge apparatus and control method of liquid discharge apparatus

A liquid ejecting apparatus includes a liquid path comprising a filter and a liquid storing chamber for supplying liquid to a liquid ejecting head. The liquid storing chamber has an inlet, a bubble retention space disposed above the inlet, a bottom disposed below the bubble retention space, and a first outlet and a second outlet. (i) The first outlet is located on one side of an imaginary center line passing through the center of a projected area, and the second outlet is located on the other side of the imaginary center line. Alternatively, (ii) the first outlet and the second outlet are located outside a projected area defined by projecting the bubble retention space onto the bottom.

Liquid ejecting apparatus and method of driving the same

A liquid discharge apparatus includes a casing, a liquid discharge head that includes a nozzle for discharging a liquid supplied from a liquid supply source provided in the casing, a waste liquid tank that accommodates in the casing a fluid emitted from the nozzle, and an outlet opening for emitting the fluid emitted from the nozzle to an outside of the casing without emitting the fluid into the waste liquid tank provided in the casing.

Liquid discharge apparatus, cleaning apparatus, and cleaning method

A valve includes a valve seat having a hole configured as a flow path, a valve body configured to open/close the flow path due to relative movement with respect to the valve seat, an opening member having a first surface fixed to one of the valve seat and the valve body, a second surface configured to separate away and abut the other one of the valve seat and the valve body, a third surface which intersects the first and second surfaces, and an opening penetrating the first and second surfaces, a fixing member that fixes the first surface to the one of the valve seat and the valve body, and an inclined portion, which makes an interval between the one of the valve seat and the valve body and the first surface long in a direction from the opening to the third surface.

Valve and manufacturing method for valve

A recording medium recording a computer readable computer program thereon, where the computer program enables the computer to generate dot recording data supplied to a dot recording device in order to perform dot recording using the dot recording device which repeats a main scanning pass and a transport based on the dot recording data so that a raster line along a main scanning direction is formed in multiple lines in a sub-scanning direction on a printing medium, where the main scanning pass is for performing the dot recording on the printing medium when an output head having a plurality of nozzles arranged in the sub-scanning direction moves in the main scanning direction, and where the transport is for enabling the printing medium to move in the sub-scanning direction, the computer program enables the computer to implement the functions of: determining a dot reduction degree for reducing the dot recording; setting a recording position of a changing target dot included in the dot recording data, according to the dot reduction degree, based on an order of performing the dot recording, where the changing target dot undergoes at least one of a thinning-out processing where the dot recording is not performed and a dot diameter shrinkage where dot size is reduced; and generating the dot recording data in which the recording position of the changing target dot is set.
