Inkjet recording apparatus

摘要

An image forming apparatus may include a mechanism for forming a corrugated shape in a sheet to be conveyed. The mechanism may include various components include one or more pressing portions, one or more ribs, one or more discharge rollers, a switching mechanism and the like. In one arrangement, ribs and pressing portions configured to create the corrugated shape may be disposed at various locations upstream or downstream of the platen, recording portion and/or nozzles thereof. In one example, pressing portions may be disposed both upstream and downstream of the nozzles of the recording portion to maintain a corrugated shape in the conveyed sheet. Various other configurations may be used.

主权项

1. An inkjet recording apparatus, comprising:
a first conveyor including a first nip member and a second nip member defining a first nip point therebetween, wherein the first conveyor nips and conveys a sheet in a conveying direction through a transport path; a recording head including nozzles that eject ink droplets onto the sheet conveyed by the first conveyor; a corrugate mechanism disposed upstream of the nozzles with respect to the conveying direction and including at least one contact member that forms a corrugated shape in the sheet; a plurality of second conveyors spaced apart from each other with respect to a scanning direction orthogonal to the conveying direction, wherein the plurality of second conveyors includes a first nip member and a second nip member defining a second nip point therebetween, and wherein the second nip point of the plurality of second conveyors is located downstream of the nozzles with respect to the conveying direction; and a spur roller disposed between a pair of second conveyors with respect to the scanning direction, wherein a lower end of the spur roller is located downstream of the second nip point of the plurality of second conveyors in the conveying direction, wherein the spur roller contacts the sheet and forms the corrugated shape in the sheet in conjunction with the plurality of second conveyors, and wherein the spur roller at least partially overlaps with one of the at least one contact member of the corrugate mechanism when viewed in the conveying direction.
