Abstract: A droplet ejection apparatus includes: a droplet ejection head that ejects droplets; a conveying member that retains a recording medium and conveys the recording medium with facing the recording medium to the droplet ejection head; a coating member that coats the conveying member with a lubricant; and a cleaning member that cleans the conveying member. The droplet ejection apparatus satisfies the following formulae (1) L2?L1 ??(1) wherein, in the formulae (1): L1 is the width, in the direction orthogonal to the conveying direction, of the cleaning of the conveying member by the cleaning member; and L2 is the width, in the direction orthogonal to the conveying direction, of coating the lubricant on the conveying member by the coating member.

Abstract: A droplet ejection apparatus includes: a droplet ejection head that ejects droplets; a conveying member that retains a recording medium and conveys the recording medium with facing the recording medium to the droplet ejection head; a coating member that coats the conveying member with a coating liquid having a repellant property to the liquid ejected from the droplet ejection head; and a cleaning member that cleans the conveying member. The droplet ejection apparatus satisfies the following formulae L3?L1, L2?L1 ??(1) wherein, in a direction orthogonal to the conveying direction; L1 is the width of ink droplet ejecting of the droplet ejection head; L2 is the width of coating the coating liquid on the conveying member by the coating member; and L3 is the width of the cleaning of the conveying member by the cleaning member.

Abstract: A droplet ejection device includes a droplet ejection head, a conveyance member, a cleaning unit and a coating unit. The droplet ejection head ejects droplets. The conveyance member retains a recording medium and conveys the recording medium to oppose the droplet ejection head. The cleaning unit cleans the conveyance member. The coating unit applies a coating liquid, with a characteristic of repelling the liquid that is ejected from the droplet ejection head, onto the conveyance member. A surface tension ?o of the coating liquid, a critical surface tension ?b of the conveyance member, and a surface tension ?i of the liquid that is ejected from the droplet ejection head satisfy the following equations (1) and (2).

Abstract: An image recording apparatus is disclosed wherein an image is recorded on a recording medium based on image information by ejecting liquid droplets from a liquid droplet ejecting head. A liquid droplet ejecting head is provided which has an ejection region substantially corresponding to a width of the recording medium. A conveyor unit is provided which conveys the recording medium to the ejection region of the liquid droplet ejecting head with the recording medium attracted and attached thereto and supported thereon. The recording medium is fed from the conveyor unit to a paper discharge section. Further, a plurality of attracting and supporting sub-units are provided which are vertically moved with the recording medium, which is delivered thereto from the conveyor unit, attracted and attached thereto and supported thereon, thereby conveying the recording medium to a subsequent step.

Abstract: A double-sided printable image recording apparatus comprising: a conveying means for conveying a recording medium, a fixed recording head for ejecting an aqueous ink and a treating liquid having nature of aggregating a colorant contained in the aqueous ink to a recording medium conveyed by the conveying means, which is arranged in a direction substantially orthogonal to a conveying direction of the recording medium, and has a printing region of a recording medium width, and an ejection controlling means for controlling ejection of the aqueous ink and the treating liquid from the fixed recording head based on image information, wherein the ejection controlling means, in a double-sided printed mode of printing on both sides of the recording medium, controls an ejection amount of a treating liquid ejected per recording medium to a smaller amount than that of a single-sided printing mode of printing only on one side, at least on a surface of a recording medium.

Abstract: A recording apparatus includes: a recording unit which records an image by ejecting ink to a conveyed recording medium; a conveying unit which returns the recording medium, on which the image has been recorded by the recording unit, in order toward an upstream side in a conveying direction; and a reversal unit which is provided at a downstream side of the conveying unit in a returning direction, the reversal unit including a plurality of holding units which respectively suck and hold a recording medium that has been returned by the conveying unit, reverse the recording medium, and send the recording medium to the recording unit.

Abstract: In an ink jet recording head having a crystalline substrate in which at least one nozzle and at least one ink chamber formed in the crystalline substrate, a gap is provided in a connecting portion between the nozzle and the ink chamber below an opening portion of the nozzle such that a variation of the ink jetting function due to an axial deviation between the nozzle and the ink chamber is restricted by absorbing the axial deviation by the gap. The gap is formed such that extension lines of wall surfaces of the ink chamber formed by etching are positioned inside the gap.

Abstract: An actuator in which an output shaft can be made to stop by a simple structure and in which actuator assured restart of the output shaft can be performed. The actuator comprises a motor, an output shaft provided with an external threading, and a connecting member having an internal threading engaged with the external threading of the output shaft. The actuator further comprises a resilient member for applying a predetermined load to the output shaft when the output shaft reaches the end of its moving range. The connecting member may comprise an internal screw member having a first protrusion formed on an outer surface thereof and a gear member having a second protrusion. When the second protrusion impacts with the first protrusion, a large starting torque is obtained. Further, two PTC thermistors are provided in a protection circuit, each thermistor allows flow of a current in only one direction, so as to prevent a reduction of a starting current.
