Abstract: Configuration with paired register rollers cooperative with a downstream head unit on a circulation route to register a print sheet, a feed route extending up to the register rollers, and feeder elements controllable for a downstream feed of print sheet along part of the feed route to the register rollers, the feeder elements being controllable for a change of feed speed or acceleration in accordance with information on a back tension of a print sheet on the circulation route.

Abstract: An inkjet printer 10 includes a platen plate 4 that has recess portions 41 and suction holes 42, and an inkjet type print head that has arrays of ink discharge nozzles right above the recess portions 41. Each suction hole 42 is set to have a first flow rate of air in a first suction path, and a second flow rate of air in a second suction path. The first suction path is made by the suction hole 42, and one of regions extending at a recess portion 41 of the platen plate 4, with the suction hole 42 intervening in between in a transfer direction. The arrays of ink discharge nozzles are disposed in the one region. The second suction path is made by the suction hole 42 and the other region at the recess portion 41. The second flow rate is smaller than the first flow rate.

Abstract: A printing device includes: a registration roller that once stops a transferred sheet and then feeds the transferred sheet toward an inkjet head unit; a sheet feed system that transfers and feeds a sheet to the registration roller; a sheet refeed system that, during both-side printing, reverses a one-side printed sheet and transfers the one-side printed sheet to the registration roller; and a controller that, during both-side printing, controls the registration roller so as to feed a sheet, which is fed by the sheet feed system and the sheet refeed system, toward the inkjet head unit in accordance with a predetermined print schedule. The controller controls the sheet feed system in accordance with the print schedule so that a speed when a sheet fed from the sheet feed system is abutted against the inkjet head unit becomes lower during both-side printing than during one-side printing.

Abstract: An inkjet printing apparatus includes: a conveyer belt with a plurality of belt holes formed therein, the conveyer belt suctioning and conveying a recording medium with a negative pressure acting on the belt holes; a platen with a plurality of through holes formed therein; a pressure-reducing unit for generating the negative pressure on a side of the platen opposite from the side thereof supporting the conveyer belt; inkjet nozzles disposed to face the platen; a distance-changing unit for changing a distance between the inkjet nozzles and a surface of the conveyer belt on which the recording medium is suctioned; and a size-adjusting unit for adjusting, when the distance is large, a size of at least one through hole in a through hole group, which includes the through holes positioned in the vicinity of the inkjet nozzles, such that the size of the at least one through hole is reduced.

Abstract: An ink-jet printer comprises: a platen plate including a plurality of recesses, which are formed and regularly arranged in a front surface by digging from the front surface toward the back surface, and a suction hole extending from a part of the bottom surface of the recess through the back surface; and a print head having ink-discharging nozzles arranged in a nozzle face which is arranged in a position facing the front surface of the platen plate. The ink-discharging nozzles are arranged between an opening end of the recess and an opening end of the suction hole excluding an area directly above the suction hole of the platen plate.

Abstract: A vehicle frame structure includes a central frame member, extending in a vehicle longitudinal direction at a central portion of a body frame. The central frame member includes a front end joined to a second front cross pipe, and a rear end joined to a second lower crossmember behind the second front cross pipe. When viewed from the side, the central frame member extends in a substantially straight line along with the left and right front reinforcing pipes. The front end portion of the central frame member is joined to the second front cross pipe at a position inwardly of a joint between the left front reinforcing pipe and the second front cross pipe, and inwardly of a joint between the right front reinforcing pipe and the second front cross pipe. Such frame structure lowers level of a center of gravity of the vehicle, and enhances rigidity.

Abstract: An inkjet printing system using a non-aqueous ink composition, wherein the head holder is configured to define an upper spatial region and a lower spatial region relative to the head holder, and is provided with a plurality of air communication holes for air communication between the upper spatial region and the lower spatial region, and the non-aqueous ink composition comprises a pigment, a pigment dispersant in such an amount that a mass ratio in solid content of the pigment dispersant to the pigment ranges from 0.2 to 2.0, and an organic solvent, the pigment dispersant comprising (A) a polyamide having a polyester side chain and/or a copolymer of vinylpyrrolidone and a C10-40 alkene, and (B) an alkyl (alkyl)acrylate copolymer dispersed in the non-aqueous ink composition.
