Abstract
Abstract A bridge for placement on top of a copying machine to control the stacking of successive original documents fed through the machine in either of two orders. The attachment includes a baffle which when raised does not intercept the original documents fed through the machine and allows the documents to be stacked in a reverse order in a collecting tray as is the usual practice. However, when the baffle is lowered, it intercepts each original document and guides it so that each document is effectively flipped over. The original documents are collected in a different tray and their order is the reverse of that usually obtained. Transport rollers in the bridge are driven by a belt coupled to a pressure roller in the bridge which engages a drive roller in the machine.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
201 words
An attachment for a copying machine, said copying machine having a plurality of drive rollers along the upper surface thereof for controlling the transport of an original document to be copied along the top of the machine and a tray in which documents transported along the top of the machine are successively deposited, said attachment comprising means for mounting said attachment on top of said machine in cooperating relating thereto, said attachment including a plurality of pressure rollers for directly and frictionally engaging the drive rollers on top of said machine for facilitating the transport of an original document along the top of said machine, a collecting tray, a baffle selectively positionable between a first position in which the original documents transported along the top of the machine are not intercepted and are allowed to be deposited in said copying machine collecting tray and a second position in which the documents are intercepted and directed to said attachment collecting tray, roller means for engaging an original document directed thereto by said baffle for moving said original document to said attachment collecting tray, and means couple between one of said attachment pressure rollers and said roller means for turning said roller means.
Claim 2
Dependent Claim
