Liquid ejecting apparatus with medium supporting unit having ribs
Provided is a liquid ejecting apparatus including a liquid ejecting unit configured to eject a liquid onto a medium (sheet) being transported in a transport direction, and a medium supporting unit arranged to face the liquid ejecting unit and configured to support the sheet being transported, wherein the medium supporting unit includes, in a width direction intersecting the transport direction, a plurality of first ribs arranged in parallel with the transport direction at an upstream side of a region (print region), where the liquid ejecting unit performs ejection onto the sheet. In addition, the liquid ejecting apparatus further includes a suction mechanism, and the medium supporting unit includes, at the upstream side, a recessed portion sectioned by the first ribs, the recessed portion including a suction hole for causing a suction force by the suction mechanism to be applied onto the sheet.
1. A liquid ejecting apparatus comprising:
a liquid ejecting unit configured to eject a liquid onto a medium being transported in a transport direction;
a medium supporting unit arranged to face the liquid ejecting unit and configured to support the medium being transported;
a suction mechanism configured to suck the medium; and
a transporting roller configured to feed the medium to the medium supporting unit,
wherein the medium supporting unit includes, in a width direction intersecting the transport direction, a plurality of first ribs arranged in parallel with the transport direction at an upstream side of a region, where the liquid ejecting unit performs ejection onto the medium, in the transport direction;
wherein the medium supporting unit includes, at the upstream side, a recessed portion sectioned by the first ribs,
wherein the recessed portion includes a suction hole for causing a suction force by the suction mechanism to be applied to the medium,
wherein an edge portion at the upstream side of the medium supporting unit includes an eave portion overlapping the transporting roller in a plan view, and
wherein an edge portion of the eave portion includes a plurality of second ribs arranged in the width direction, and
wherein the height of the plurality of first ribs and the height of the plurality of second ribs are substantially the same.
2. The liquid ejecting apparatus according to claim 1 , wherein the first ribs are arranged at equal intervals.
3. The liquid ejecting apparatus according to claim 1 , wherein the first ribs are formed integrally with or separately from the medium supporting unit.
4. The liquid ejecting apparatus according to claim 3 , wherein when the first ribs are formed separately from the medium supporting unit, the first ribs are composed of a frame portion having a plate shape and sectioning a rectangular hole portion formed in the width direction, the frame portion being in parallel with the transport direction when arranged on the medium supporting unit.
5. The liquid ejecting apparatus according to claim 1 , wherein a slit is formed between the first ribs, which are adjacent to each other.
