Abstract

In one example, a media support includes a sheet of elongated suction cups. In another example, a media support includes an arrangement of elongated and/or circular suction cups in which the density of the suction cups varies between different parts of the support.

First claim

What is claimed is:

1. A media support, comprising a sheet of elongated suction cups and circular suction cups, wherein each elongated suction cup has a length in a first direction, a width in a second direction orthogonal to the first direction, and a depth in a third direction orthogonal to the first and second directions, the length being greater than the width, and wherein each suction cup:
is recessed into the sheet in the third direction along a surface of the sheet such that at least some of the suction cup is below the surface of the sheet in the third direction; and
has a port through which air may be evacuated from the suction cup with the port of each suction cup separate from the port of any other suction cup.

2. The media support of claim 1 , wherein the sheet is a single sheet.

3. The media support of claim 1 , wherein the sheet comprises a flexible sheet.

4. The media support of claim 1 , wherein each suction cup includes a rim that protrudes above the surface of the sheet.

5. The media support of claim 4 , wherein the rim is formed at a perimeter of a flexible ring surrounding the port in space such that the ring may flex into a recess when a media supported on the sheet is sucked onto the rim.

6. A media support, comprising:
a platen having an array of vacuum holes therein through which vacuum may be applied to media on the platen; and
a sheet of elongated suction cups and circular suction cups covering the platen, wherein each elongated suction cup has a length in a first direction, a width in a second direction orthogonal to the first direction, and a depth in a third direction orthogonal to the first and second directions, the length being greater than the width, and wherein each suction cup:
is recessed into the sheet in the third direction along a surface of the sheet such that at least some of the elongated suction cup is below the surface of the sheet in the third direction; and
has a port through which air may be evacuated from the suction cup with the port of each suction cup separate from the port of any other suction cup and with the port of each suction cup aligned to a vacuum hole on the platen so that vacuum may be applied to the suction cup through the vacuum hole.

7. The media support of claim 6 , wherein the sheet is detachable from the platen.
