Abstract
An inkjet recording apparatus includes a sheet conveyance portion, a pair of registration rollers, a recording portion, a plate portion, a suction roller, and an exhaust portion. The exhaust portion is disposed over an area from upstream of the recording portion to upstream of the pair of registration rollers with respect to the sheet conveyance direction and sucks air from above the conveyance belt and the plate portion in the direction away from the conveyance belt. The exhaust portion includes an exhaust hood and an exhaust fan. The exhaust fan guides the air in the exhaust hood through an air inlet into a recording potion housing and then passes the air through an exhaust outlet to discharge it via an air flow passage.
Claims8
An inkjet recording apparatus comprising:
- a sheet conveyance portion including an endless conveyance belt, the sheet conveyance portion conveying a sheet;
- a pair of registration rollers which feeds the sheet toward the sheet conveyance portion;
- a recording portion disposed opposite an outer circumferential surface of the conveyance belt and including a recording head ejecting ink, the recording portion recording an image by ejecting the ink to the sheet conveyed by the conveyance belt;
- a plate portion adjacent to, upstream of, the recording portion with respect to a sheet conveyance direction and disposed opposite the outer circumferential surface of the conveyance belt, the plate portion extending in the sheet conveyance direction and in a sheet width direction orthogonal to the sheet conveyance direction;
- a suction roller adjacent to, upstream of, the plate portion with respect to the sheet conveyance direction and disposed opposite the outer circumferential surface of the conveyance belt, the suction roller bringing the sheet into contact with the outer circumferential surface of the conveyance belt;
- and
- an exhaust portion disposed over an area from upstream of the recording portion to upstream of the pair of registration rollers with respect to the sheet conveyance direction, the exhaust portion sucking air from above the conveyance belt and the plate portion in a direction away from the conveyance belt, wherein
- the recording portion holds the recording head and includes a recording portion housing having an air inlet, an exhaust outlet, and an air flow passage disposed between the air inlet and the exhaust outlet, adjacent to the recording head, and
- the exhaust portion includes:
- an exhaust hood extending in the sheet conveyance direction and in the sheet width direction from upstream of the recording portion to upstream of the pair of registration rollers with respect to the sheet conveyance direction, the exhaust hood covering above the conveyance belt, the plate portion, the suction roller, and the pair of registration rollers extends, and
- an exhaust fan which guides the air in the exhaust hood through the air inlet into the recording potion housing and which then pass the air through the exhaust outlet to discharge the air via the air flow passage.
