Abstract
Abstract A combined input scanner and output scanner has a frame assembly, a document transport to transport a document through the scanner in a path in a first direction and, a copy sheet transport to transport a copy sheet through the scanner a document registration means and a copy sheet registration means, the document registration gate including a cover pivotally mounted on the machine for movement between an open and closed position over the document transport path, said cover having at least one document registration gate adjacent its downstream end which extends into the document transport path to register the lead edge of a document when the cover is in the open position, the copy sheet registration means including at least one copy sheet registration gate in the copy sheet transport path to register the lead edge of a copy sheet when said cover is in the open position. The cover has a tab for removing the at least one copy sheet registration gate from the copy sheet transport when the cover is in the closed position over the document transport path.

Claim 7
Dependent Claim
32 words
The scanner of claim 3 wherein said cover is pivotally mounted at the downstream end of the document transport path and said integral document registration gate is adjacent said covers downstream end.
Claim 8
Dependent Claim
42 words
The scanner of claim 6 wherein the copy sheet transport path is in a direction opposite said direction of document transport and said at least one copy sheet registration gate is positioned at the downstream end of the copy sheet transport path.
Claim 9
Dependent Claim
70 words
The scanner of claim 2, wherein said at least one copy sheet registration gate has a positioning tab and said means associated with said cover comprises at least one positioning tab on said cover for engagement with said positioning tab on said copy sheet registration gate when said cover is in the closed position to remove said at least one copy sheet registration gate from said copy sheet transport path.
Claim 10
Dependent Claim
54 words
The scanner of claim 2 wherein said document transport and copy sheet transport include a first pair of synchronously driven rotatable drive rolls each drive roll forming a feeding nip for a document with a document feed idler roll and a feeding nip for a copy sheet with a copy sheet feed idler roll.
Claim 11
Dependent Claim
31 words
The scanner of claim 9 wherein the document feeding nip is on top of the drive roll and the copy sheet feeding nip is at the bottom of the drive roll.
Claim 12
Dependent Claim
56 words
The scanner of claim 9 wherein the copy sheet feed idler roll in the upstream end of the copy sheet transport path is mounted on an arm for pivotal movement toward one of said drive rolls forming a feeding nip therebetween and away from said one drive roll to enable insertion of a copy sheet therebetween.
Claim 13
Dependent Claim
