Abstract

Abstract Document feed apparatus for transporting one document at a time from a supply tray to a work station and back to the supply tray on completion of the work cycle, the apparatus having relatively high speed first document transport means for feeding each document to the work station and returning the document to the supply tray, relatively low speed second transport means for bringing the next document forward to a point adjacent the work station inlet, and means to maintain documents returned to the supply tray segregated from documents awaiting feeding to the work station, the last mentioned means being adapted, where the cycle is repeated, to automatically move onto the topmost one of the returned documents following return of the last document to the supply tray.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 163 words
In a document handling apparatus having plural document transport means, one of said transport means being adapted for bidrectional transporting movement, the combination of: gear means including drive gear and a pair of first driven gears in meshing engagement with said drive gear such that rotation of said drive gear rotates said first driven gears in opposite directions; clutch means for coupling one or the other of said first driven gears with said one transport means whereby to selectively move said one transport means forward or backward; and a second driven gear for a second one of said transport means, said second driven gear being in meshing engagement with one of said first driven gears whereby to move said second transport means forward so that on rotation of said drive gear, said first driven gears and said clutch means cooperate to selectively move said one transport means either forward or backwards while said second driven gear simultaneously moves said second transport means forward.
Claim 2
Dependent Claim 163 words
In a document handling apparatus having plural document transport means, one of said transport means being adapted for bidrectional transporting movement, the combination of: gear means including drive gear and a pair of first driven gears in meshing engagement with said drive gear such that rotation of said drive gear rotates said first driven gears in opposite directions; clutch means for coupling one or the other of said first driven gears with said one transport means whereby to selectively move said one transport means forward or backward; and a second driven gear for a second one of said transport means, said second driven gear being in meshing engagement with one of said first driven gears whereby to move said second transport means forward so that on rotation of said drive gear, said first driven gears and said clutch means cooperate to selectively move said one transport means either forward or backwards while said second driven gear simultaneously moves said second transport means forward.
Claim 3
Dependent Claim 55 words
The apparatus according to claim 1 including a third driven gear for moving a third one of said document transport means backwards, said third driven gear being in meshing engagement with the other of said first driven gears whereby on rotation of said drive gear, said third driven gear moves said third transport means backwards.
Claim 4
Dependent Claim 22 words
The apparatus according to claim 1 including second clutch means for selective coupling said second driven gear with said second transport means.
Claim 5
Dependent Claim 47 words
The apparatus according to claim 1 in which said clutch means comprises first and second clutches for selectively coupling individual ones of said first driven gears with said one transport means, and a third clutch for selectively coupling said second driven gear with said second transport means.
