摘要： A print head cap includes a bottom surface; and a ring-like lip. The ring-like lip surrounds the bottom surface, protrudes toward a nozzle surface of a print head of an ink jet printer and is elastically deformable. The ring-like lip is pressed onto the nozzle surface to cover the nozzle surface therewith. The ring-like lip has corners that change the direction surrounding the bottom surface. The corners of the ring-like lip are more elastically deformable than the other portions of the ring-like lip.

摘要： An inkjet recording apparatus includes: (a) a medium supporter; (b) an inkjet head; and (c) a medium feeder including a first roller and a second roller for cooperating with each other to nip the recording medium, for thereby feeding a recording medium outwardly of the medium supporter. The first roller is displaceable between a projecting position and a non-projecting position, such that the first roller projects out from the medium supporter when being placed in the projecting position. The inkjet recording apparatus further includes (d) a feeder controller configured to control the medium feeder, for causing the second roller to be displaced toward the first roller upon placement of the first roller in the projecting position so as to cooperate with the first roller to nip the recording medium, and causing the first roller and/or the second roller to be rotated, whereby the recording medium is fed outwardly of the medium supporter while the recording medium is being at least partially separated from the medium supporter by the placement of the first roller in the projecting position.

摘要： A conveyance apparatus includes a platen having a flat supporting surface that supports a conveyor belt, from its inside, being stretched between first and second rollers. The apparatus further includes an encoder roller disposed between the first roller and the platen so as to be in contact with the conveyor belt from its inside, and a rotary encoder that follows the encoder roller to rotate. The belt is inclined between the first roller and the platen so as to form an obtuse angle with the supporting surface. A contact position between the encoder roller and the belt is in between a first imaginary plane including the supporting surface, and a second imaginary plane spreading through the nearer one, to the first roller, of both ends of the supporting surface in a direction of conveyance by the belt on the supporting surface.

摘要： An object of the present invention is to reduce force acting, when an ink-jet head moves, on a distal end portion of an ink supply pipe connected to a brancher, to thereby prevent damage to the ink supply pipe as much as possible. An ink supplier, which supplies ink to respective ink introduction ports of at least one ink-jet head, has an ink supply pipe connected to an ink cartridge, a brancher to which a distal end portion of the ink supply pipe connected, and branch pipes extending from the brancher to the respective ink introduction ports. The brancher and the branch pipes are adapted to move integrally with the at least on ink-jet head, and in addition the distal end portion of the ink supply pipe and the brancher are connected to each other in a relatively rotatable manner.

摘要： An ink-jet recording apparatus has rollers, an endless conveyor belt, a conveyor belt driving mechanism, an ink-jet head, an absorber, a scraper, a supplier, and a supply controller. The endless conveyor belt spans the rollers. The conveyor belt driving mechanism rotates the rollers so as to move, in a predetermined conveyance direction, a record medium disposed on one surface of the conveyor belt. The ink-jet head has nozzles that eject ink to a record medium. The absorber absorbs cleaning fluid and applies the cleaning fluid to the one surface of the conveyor belt by coming into contact with the one surface of the conveyor belt. The scraper comes into contact with the one surface of the conveyor belt and scrapes the cleaning fluid attached to the one surface of the conveyor belt. The supplier supplies cleaning fluid to the absorber. The supply controller controls a supply of cleaning fluid from the supplier to the absorber, in such a manner that the supply controller, in response to a print command, makes the supplier supply cleaning fluid to the absorber for a first period of time before the conveyor belt driving mechanism rotates the rollers to make the conveyor belt start traveling.

摘要： An inkjet printer includes a pair of rollers whose axes of rotation are parallel to each other. An endless conveyor belt is stretched between the pair of rollers. The conveyor belt conveys a print medium in the conveyance direction attendant upon rotations of the pair of rollers. The conveyor belt has, on its outer circumferential surface, an ink receiving groove extending in a direction intersecting the conveyance direction. The depth of the ink receiving groove gradually increases toward the center of the ink receiving groove in the conveyance direction in at least one of regions continuous from front and rear ends of the ink receiving groove in the conveyance direction.
