Abstract

The invention is directed to a media tray for an imaging apparatus for receiving a sheet of media. The media tray includes a base having a first side region and a second side region, a first sheet support member, a second sheet support member, a first mechanism, a second mechanism, and a force applying mechanism. The first and second mechanisms pivotally couple the first and second sheet support members to the side regions of the base, respectively. The force applying mechanism applies a force on the first and second sheet support members such that each of the first and second sheet support members diverge upwardly and outwardly from the base. The force applying mechanism includes a first cam member or first spring mechanism positioned between the first sheet support member and the base and a second cam member or second spring mechanism positioned between the second sheet support member and the base.

wherein as said media support assembly is moved in a first direction in relation to said base, said at least one spring mechanism engages said upper surface of said base to force an outer portion of said support unit to move upwardly in relation to said base.

7. The media tray of claim 6, wherein said base is slideably coupled to said imaging apparatus.

8. The media tray of claim 7, wherein said media support assembly further comprises a base extension positioned above said base and slideably coupled to said base, said base extension having a first side region and a second side region.

9. The media tray of claim 8, wherein said media support assembly further comprises a first sheet support member pivotally coupled to said first side region of said base extension, said first sheet support member including a downwardly extending first spring mechanism for engaging said upper surface of said base;

and, a second sheet support member pivotally coupled to said second side region of said base extension, said second sheet support member including a downwardly extending second spring mechanism for engaging said upper surface of said base, wherein as said base extension is slid outwardly from said base, said first spring mechanism and said second spring mechanism engage said upper surface of said base to force each of said first sheet support member and said second sheet support member to pivot upwardly and away from said base.

10. The media tray of claim 9, wherein said first sheet support member is pivotally coupled to said first side region of said base extension by a first clip mechanism, and wherein said second sheet support member is pivotally coupled to said second side region of said base extension by a second clip mechanism.

11. An imaging apparatus, comprising:

media feeding means for transporting a sheet of media;

imaging means for forming an image on said sheet of media transported by said media feed means; and

a media receiving device for receiving said sheet having an image from said media feed means, said media receiving device including;

a base having an inclined region; and

a media support assembly movably coupled to said base, said media support assembly including a support unit for supporting at least a portion of said sheet of media, said support unit including at least one downwardly extending cam member having at least one cam surface for engaging said inclined region of said base,

wherein as said media support assembly is moved in a first direction in relation to said base, said at least one cam surface engages said inclined region of said base to force an outer portion of said support unit to move upwardly in relation to said base.

12. The imaging apparatus of claim 11, wherein said base is slideably coupled to a frame of said imaging apparatus, said base having an upper surface which includes said inclined region.

13. The imaging apparatus of claim 12, wherein said media support assembly further comprises a base extension positioned above said base and slideably coupled to said base, said base extension having a first side region and a second side region.

14.
