Abstract:
A washing blade, a manufacturing method thereof, and a washing device for a liquid discharging head are provided to compensate flatness and rigidity of a tip end portion over entire length, and to achieve mounting accuracy thereof. A washing blade consists of a supporting plate(44) and a wiping unit(43). The supporting plate is coated with an adhesive agent layer at a front surface. The wiping unit is contacted with a liquid discharging area and slid. The wiping unit is formed by a single piece of an elastic unit(57) made of a synthetic resin, at the adhesive agent layer. A tip end portion is cut at a predetermined shape. A manufacturing method of the washing blade includes a step of cutting the tip end portion of the elastic unit at the predetermined shape to form the wiping unit. A washing device for a liquid discharging head comprises the liquid discharging head, the washing blade, a moving mechanism, and a switching member. The liquid discharging head is formed with the liquid discharging area to discharge liquid from by a liquid discharging nozzle. The washing blade is contacted with the liquid discharging area and slid, to clean the liquid discharging area. The moving mechanism is used to move the washing blade to the liquid discharging head. The switching member is used to move the washing blade inversely from a sliding position for the washing blade when moving the washing blade to one side surface of the liquid discharging head by the moving mechanism, and to return the washing blade from the sliding position when moving the washing blade to the other side surface of the liquid discharging head by the moving mechanism.
Abstract:
An organic luminescent material-containing solution contains an organic electroluminescent material and a solvent. The organic electroluminescent material at least contains a host and a dopant. The host is an anthracene derivative and is dissolved in the solvent with a content of 0.5 weight percent or more. The solvent is preferably a cyclic ketone. The solvent preferably contains a cyclohexanone derivative as the cyclic ketone.
Abstract:
An inkjet printer (100) having a plurality of nozzles which discharge droplets of ink to cause them to land on paper (P), which landing results in dots recording information including characters and/or images. The inkjet printer (100) includes a line head (120) having a driving element which causes droplets of ink to be discharged from the nozzles, wherein the line head (120) is driven in such a manner that the same location on the paper (P) is scanned only once for single printing, one or a plurality of droplets of ink being used for forming a single dot, the diameter of the dot being varied by the number of droplets of ink.
Abstract:
A liquid ejecting head having an ink ejecting surface (6) with rows of ink ejecting holes (13) for ejecting ink for each color, a method of cleaning the liquid ejecting head, and a liquid ejecting device, the method of cleaning the liquid ejecting head comprising the steps of moving a cleaning roller (7) cylindrically formed of an elastic material relative to the liquid ejecting head in the state of being brought into contact with the ink ejecting surface (6) of the liquid ejecting head, and sucking ink (15) in the ink ejecting holes (13) by a pressure variation in the ink ejecting holes (13) during the movement, whereby the ink ejecting surface (6) having the ink ejecting holes (13) is not damaged and a cleaning effect on the ink ejecting surface (6) near the ink ejecting holes (13) can be increased.
Abstract:
An ink-jet printer comprises a line head having heating elements (121d) for ejecting ink droplets from nozzles. The heating elements (121d) are arrayed generally perpendicularly to the direction where the sheet is fed. The heating elements(121d) corresponding to the nozzles and arrayed spatially are grouped into blocks of predetermined number of heading elements (121d). The line head supplies a phase signal PH to each set of blocks of heating elements to drive the set simultaneously in time-division manner. The dot position error on the sheet is small, and the momentary maximum power consumption during time-division drive is lowered.
Abstract:
A print head (1) is provided with at least ink-pressuring cells (9), heating elements (8) and ink-ejection nozzles (3). In addition, the print head (1) includes substrate members (6) which form side surfaces and one end surface of the ink-pressurising cells (9) and which are provided with the heating elements (8); a nozzle-formed member (2) which forms the other end surface of the ink-pressurising cells (9) and in which the ink-ejection nozzles (3), which correspond to the ink- pressurising cells (9), are formed; and a head frame (4) which supports the nozzle- formed member (2).

A print head is provided with at least ink-pressurizing cells, heating elements, and ink-ejection nozzles. In addition, the print head includes substrate members which form side surfaces and one end surface of the ink-pressurizing cells, and which are provided with the heating elements; a nozzle-formed member which forms the other end surface of the ink-pressurizing cells, and in which the ink-ejection nozzles, which individually correspond to the ink-pressurizing cells, are formed; and a head frame which supports the nozzle-formed member.
Abstract:
An inkjet head includes a head cap for protecting an ink discharge surface of a print head and a cleaning roller for cleaning the ink discharge surface of the print head. The head cap moves relative to and is removably mounted to the print head including the ink discharge surface with an ink discharge hole for discharging ink supplied from an ink cartridge. The cleaning roller is provided at a print head side of the head cap in the longitudinal direction of the print head. By virtue of this structure, it is possible to reduce the size of a printer body. The invention aims at reducing the size of the printer body by providing the cleaning member at the head cap for protecting the ink discharge surface.
