An image recording apparatus forms an image on a recording medium including a liquid accommodation layer by landing a liquid to the liquid accommodation layer of the recording medium. The image recording apparatus includes a first unit that performs pre-processing of landing the liquid containing a material with absorbability lower than that of the liquid accommodation layer to an edge of an image formation region at which the image is scheduled to be formed; and a second unit that forms the image at the image formation region of the recording medium after the first unit performs the pre-processing.

Image recording apparatus, image recording method, program, and program recording medium for preventing moisture infiltration to a recording medium

An image recording device which includes a control unit which alternately performs, main-scannings in which the recording head is moved in the main-scanning direction while the recording head ejecting the liquid to form line images that extend in the main scanning direction and are adjacent to each other in the sub-scanning direction, and sub-scannings in which the recording head is moved in the sub-scanning direction, and a detection unit which detects a displacement of a mark which is formed on the recording medium in the sub-scanning direction, wherein the control unit adjusts a movement amount of the recording head which is moved in the sub-scanning direction in the sub-scannings on the basis of a detection result of the detection unit.

Digital still camera

A method of producing an ink jet recording head, which includes () fixing a passage unit in which a nozzle pate having a nozzle opening, a spacer forming a common ink chamber, and an elastic plate having a thick portion abutting against an end of a piezoelectric vibrating element are stacked, to an opening of a frame having an overhang portion which overhangs to a vicinity of the thick portion, () inserting a vibrating element unit into the frame, the vibrating element unit being configured by fixing piezoelectric vibrating elements operating in a longitudinal vibration mode to a fixing substrate, and () injecting an adhesive into a groove formed in a region opposing the fixing substrate of the frame.

Method of producing an ink jet recording head

Actuator units independently dedicated to nozzles divided into a plurality of groups are fixed to a common flow path unit having the nozzles formed therein with through holes aligned with one another. Heads of various types can be formed by using the actuator units of the same design only by changing the mode of arrangement of the nozzles in accordance with the purpose.

Laminated ink jet recording head

A pressurizing chamber is formed as a recess by half etching of a silicon single-crystal substrate . A nozzle communicating hole through which the pressurizing chamber is connected to a nozzle opening is formed as a through hole which is smaller in width than the pressurizing chamber . The pressurizing chamber is connected to the nozzle opening in the other face via the nozzle communicating hole while reducing the volume of the pressurizing chamber to a degree as small as possible. The silicon single-crystal substrate is used as a member constituting a spacer so that an ink drop of a reduced ink amount suitable for high density printing flies with high positioning accuracy.

Ink jet recording head having spacer with etched pressurizing chambers and ink supply ports

An ink jet print head is disclosed which includes a flow path unit with nozzles, a pressure generating unit disposed on the flow path unit and having ink pressure chambers formed behind the respective nozzles, and piezoelectric/electrostrictive elements each disposed on a wall defining a corresponding ink pressure chamber, for deforming the wall to change a pressure of the ink pressure chamber, whereby the ink in the ink pressure chamber is jetted through the corresponding nozzle. The pressure generating unit includes a spacer plate having windows which closed by a closure plate and a connecting plate disposed on the spacer plate, so as to give the respective ink pressure chambers. The connecting plate has communication holes through which the ink pressure chambers communicate with the nozzles. The spacer plate, closure plate and connecting plate are formed from respective ceramic green sheets, which are laminated on each other and fired into an integral ceramic structure as the pressure generating unit. The piezoelectric/electrostrictive element includes a pair of electrodes and a piezoelectric/electrostrictive layer, which are formed by a film-forming method on an outer surface of the closure plate.

Multi-layer ink jet print head and manufacturing method therefor

An ink jet type recording head of a multi-layer structure including a pressure generating unit and a flow path unit. The pressure generating unit is composed of a ceramic vibrating member with piezoelectric transducers on the surface thereof, a ceramic first spacer member with a plurality of through-holes forming pressure chambers, and a lid member having through-holes through which the pressure chambers are communicated with a reservoir, these members being joined by firing in such a manner that a diaphragm is placed on one surface of the first spacer member, and the lid member is sealingly set on the other surface of the spacer member. The flow path unit includes an ink supplying member formed with a metal plate which has through-holes through which the pressure chambers are communicated with nozzle openings and the reservoir is communicated with the pressure chambers, a second spacer member having the reservoir and through-holes through which the pressure chambers are communicated with the nozzle openings, and a nozzle plate member, which members are joined together in such a manner that the ink supplying member is placed on one surface of the second spacer member, and the nozzle plate member is fixedly placed on the other surface of the second spacer member. The outer surface of the lid member is joined to the outer surface of the ink supplying member with a macromolecular adhesive agent.
