Abstract
Abstract A dual mode document handling apparatus in which either individual cut sheet documents or computer-form web documents are advanced to an exposure station of a reproducing machine. Successive cut sheet documents are advanced in a first direction to the exposure station. Successive incremental lengths of a computer form web document are moved to the exposure station in a second direction substantially normal to the first direction. The machine operator may select either computer-form web document feeding or cut sheet document feeding.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
99 words
A dual mode document handling apparatus for advancing either individual cut sheet documents or computer form web documents to an exposure station of a reproducing machine, including: means for advancing, in a first direction, successive cut sheet documents to the exposure station; means for moving, in a second direction substantially normal to the first direction, successive incremental lengths of a computer form web document to the exposure station; and operator actuatable means for selecting either said moving means of said advancing means to feed either cut sheet documents or incremental lengths of a web document to the exposure station.
Claim 2
Dependent Claim
99 words
A dual mode document handling apparatus for advancing either individual cut sheet documents or computer form web documents to an exposure station of a reproducing machine, including: means for advancing, in a first direction, successive cut sheet documents to the exposure station; means for moving, in a second direction substantially normal to the first direction, successive incremental lengths of a computer form web document to the exposure station; and operator actuatable means for selecting either said moving means of said advancing means to feed either cut sheet documents or incremental lengths of a web document to the exposure station.
Claim 3
Dependent Claim
31 words
A document handling apparatus according to claim 1, wherein said moving means includes friction feed means for moving successive incremental lengths of the computer form web document to the exposure station.
Claim 4
Dependent Claim
23 words
A document handling apparatus according to claim 2, wherein the exposure station includes a substantially planar, stationary, transparent platen for receiving documents thereon.
Claim 5
Dependent Claim
22 words
A document handling apparatus according to claim 3, wherein said friction feed means is positioned after the downstream edge of said platen.
Claim 6
Dependent Claim
65 words
A document handling apparatus according to claim 4, wherein said friction feed means includes: a roller; means for rotating said roller; a ball; and means for resiliently urging said ball into contact with said roller to define a nip for receiving the computer form web document so that rotation of said roller advances successive incremental lengths of the computer form web document onto the platen.
Claim 7
Dependent Claim
18 words
A document handling apparatus according to claim 5, wherein said advancing means includes a recirculating handling document unit.
Claim 8
Independent Claim
104 words
A method of advancing either individual cut sheet documents or computer form web documents to an exposure station of a reproducing machine, including the steps of: advancing, in a first direction, successive cut sheet documents to the exposure station; moving, in a second direction substantially normal to the first direction, successive incremental lengths of a computer form web document to the exposure station; and selecting either said step of moving successive incremental lengths of the computer form web document of said step of advancing the cut sheet document to feed either sheet documents or incremental lengths of a web document to the exposure station.
Claim 9
Independent Claim
104 words
A method of advancing either individual cut sheet documents or computer form web documents to an exposure station of a reproducing machine, including the steps of: advancing, in a first direction, successive cut sheet documents to the exposure station; moving, in a second direction substantially normal to the first direction, successive incremental lengths of a computer form web document to the exposure station; and selecting either said step of moving successive incremental lengths of the computer form web document of said step of advancing the cut sheet document to feed either sheet documents or incremental lengths of a web document to the exposure station.
Claim 10
Dependent Claim
30 words
A method according to claim 7, wherein said step of moving includes the step of moving frictinally successive incremental lengths of the computer form web document to the exposure station.
Claim 11
Dependent Claim
30 words
A method according to claim 8, further including the step of receiving the sheet document or incremental length of computer form web document on a substantially planar, stationary, transparent platen.
Claim 12
Dependent Claim
63 words
A method according to claim 9, wherein said step of moving frictionally includes the steps of: resiliently urging a ball, positioned after the downstream edge of the platen, into contact with a roller to define a nip for receiving the computer form web document; and rotating the roller to advance successive incremental lengths of the the computer form web document onto the platen.
Claim 13
Dependent Claim
115 words
An electrophotographic printing machine of the type having a generally planar, substantially transparent platen at an imaging station for receiving either individual cut sheet documents or computer form web documents for copying thereat, including: means for advancing, in a first direction, successive cut sheet documents to the platen of the imaging station; means for moving, in a second direction substantially normal to the first direction, successive incremental lengths of a computer form web document to the platen of the imaging station; and operator actuatable means for selecting either said moving means or said advancing means to feed either cut sheet documents or incremental lengths of a web document to the platen on the imaging station.
Claim 14
Dependent Claim
115 words
An electrophotographic printing machine of the type having a generally planar, substantially transparent platen at an imaging station for receiving either individual cut sheet documents or computer form web documents for copying thereat, including: means for advancing, in a first direction, successive cut sheet documents to the platen of the imaging station; means for moving, in a second direction substantially normal to the first direction, successive incremental lengths of a computer form web document to the platen of the imaging station; and operator actuatable means for selecting either said moving means or said advancing means to feed either cut sheet documents or incremental lengths of a web document to the platen on the imaging station.
Claim 15
Dependent Claim
33 words
A printing machine according to claim 11, wherein said moving means includes friction feed means for moving successive incremental lengths of the computer form web document to the platen of the imaging station.
Claim 16
Dependent Claim
21 words
A printing machine according to claim 12, wherein said friction feed means is positioned after the downstream edge of the platen.
Claim 17
Dependent Claim
64 words
A printing machine according to claim 13, wherein said friction feed means includes: a roller; means for rotating said roller; a ball; and means for resiliently urging said ball into contact with said roller to define a nip for receiving the computer form web document so that rotation of said roller advances successive incremental lengths of the computer form web document onto the platen.
Claim 18
Dependent Claim
17 words
A printing machine according to claim 14, wherein said advancing means includes a recirculating handling document unit.
