Abstract
Abstract An apparatus in which the manual placement of successive original documents onto the platen of a reproducing machine is facilitated. A plurality of original documents are located on the platen with the lowermost document being positioned thereon for reproduction. After being reproduced, the lowermost document is removed from the platen while the uppermost document is retained thereon enabling it to be subsequently reproduced.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
156 words
An apparatus for assisting in the manual placement of successive original documents onto the platen of a reproducing machine, including: a housing member having an open ended compartment for holding a plurality of original documents therein, said housing member being positioned on the platen and arranged to locate the lowermost original document in position to be reproduced; a plate member extending outwardly across the width of the open end of the compartment in said housing member and adapted to facilitate the removal of the lowermost original document therefrom; and a roller mounted in the compartment of said housing member and contacting the uppermost original document therein, said roller being rotatable in one direction to facilitate the insertion of original documents in the compartment of said housing member and being non-rotatable in the opposed direction to frictionally prevent the movement of the uppermost original document during the removal of the lowermost original document from said housing member.
Claim 2
Independent Claim
156 words
An apparatus for assisting in the manual placement of successive original documents onto the platen of a reproducing machine, including: a housing member having an open ended compartment for holding a plurality of original documents therein, said housing member being positioned on the platen and arranged to locate the lowermost original document in position to be reproduced; a plate member extending outwardly across the width of the open end of the compartment in said housing member and adapted to facilitate the removal of the lowermost original document therefrom; and a roller mounted in the compartment of said housing member and contacting the uppermost original document therein, said roller being rotatable in one direction to facilitate the insertion of original documents in the compartment of said housing member and being non-rotatable in the opposed direction to frictionally prevent the movement of the uppermost original document during the removal of the lowermost original document from said housing member.
Claim 3
Dependent Claim
24 words
An apparatus as recited in claim 1, further including means for indicating that the lowermost original document may be removed from said housing member.
Claim 4
Dependent Claim
23 words
