Media support
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.
1. A media support, comprising a sheet of elongated 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 each elongated suction cup having a port through which air may be evacuated from the elongated suction cup with each port separate from the port of any other elongated suction cup; and
the sheet includes circular suction cups each having a port through which air may be evacuated from the circular suction cup, with a first array of only circular suction cups grouped together in one corner of the sheet and an array of only elongated suction cups in another part of the sheet, the suction cups in the first array of only circular suction cups arrayed in a first density and the suction cups in the array of only elongated suction cups arrayed in a second density less than the first density.
2. The media support of claim 1 , with a second array of only circular suction cups arranged in a series of lines along only two sides of the sheet that meet at the one corner.
3. The media support of claim 1 , wherein the sheet comprises a flexible sheet.
4. The media support of claim 1 , wherein the length of each elongated suction cup is oriented parallel to the length of each of the other elongated suction cups.
5. The media support of claim 1 , wherein the length of some of the elongated suction cups is oriented perpendicular to the length of other of the elongated suction cups.
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 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 each of the elongated suction cups having a port through which air may be evacuated from the elongated suction cup with each port separate from the port of any other elongated suction cup and each port aligned to a vacuum hole on the platen so that vacuum may be applied to the elongated suction cup through the vacuum hole;
wherein the sheet includes circular suction cups each having a port through which air may be evacuated from the circular suction cup and aligned to a vacuum hole on the platen so that vacuum may be applied to the circular suction cup through the vacuum hole, with an array of only circular suction cups grouped together in one corner of the sheet and an array of only elongated suction cups spread over another part of the sheet, the array of only circular suction cups arrayed in a first density and the array of only elongated suction cups arrayed in a second density less than the first density.
7. The media support of claim 6 , wherein the sheet is detachable from the platen.
8. The media support of claim 6 , wherein each elongated suction cup includes a flexible ring surrounding the port in a recess such that the ring may flex into the recess when suction is applied to media supported on the sheet.
9. The media support of claim 1 , wherein some or all of the elongated suction cups are oval suction cups.
10. The media support of claim 1 , wherein some of or all of the elongated suction cups are L shaped and the port of each L shaped suction cup is located at the corner of the L.
11. The media support of claim 6 , wherein the sheet comprises a flexible sheet detachable from the platen.
12. 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 flexible sheet having elongated suction cups and circular suction cups therein 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 each of the suction cups having a port through which air may be evacuated from the suction cup with each port separate from the port of any other suction cup and each port aligned to a vacuum hole on the platen so that vacuum may be applied to the suction cup through the vacuum hole, the elongated suction cups arranged in a first array over a first part of the sheet and the circular suction cups arranged in a second array over a second part of the sheet not overlapping the first part of the sheet.
13. The media support of claim 12 , wherein the second part of the sheet includes one corner of the sheet and some or all of the circular suction cups in the second array are grouped together in the one corner.
14. The media support of claim 13 , wherein the in the first array is less dense than the second array.
