Abstract
Abstract A reproducing apparatus includes an illuminating station and a system for forming an image on a sheet of support material of an object positioned at the illuminating station. The viewing station includes a transparent viewing platen having a registration edge against which the object is placed for imaging. A support member is arranged adjacent to the registration edge of the platen. Apparatus is provided for supporting the member in a first position above the level of the platen, and for supporting the member for movement to a second position downwardly of the first position in response to the urging of an object placed on the viewing platen.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
148 words
In a reproducing apparatus including an illuminating station and means for forming an image on a sheet of support material of an object positioned at said illuminating station, said illuminating station including a transparent viewing platen having a registration edge against which said object is placed for imaging, a catch tray arranged adjacent said registration edge of said platen, a retractable support member arranged adjacent said registration edge of said platen and above said catch tray, document decelerating means supported by said retractable support member, means for supporting said support member in a first position above the level of said platen whereby said document decelerating means is positioned for decelerating documents as they may be advanced into said catch tray and for retracting said support member to a second position downwardly of said first position in response to the urging of an object placed on said viewing platen.
Claim 2
Dependent Claim
148 words
In a reproducing apparatus including an illuminating station and means for forming an image on a sheet of support material of an object positioned at said illuminating station, said illuminating station including a transparent viewing platen having a registration edge against which said object is placed for imaging, a catch tray arranged adjacent said registration edge of said platen, a retractable support member arranged adjacent said registration edge of said platen and above said catch tray, document decelerating means supported by said retractable support member, means for supporting said support member in a first position above the level of said platen whereby said document decelerating means is positioned for decelerating documents as they may be advanced into said catch tray and for retracting said support member to a second position downwardly of said first position in response to the urging of an object placed on said viewing platen.
Claim 3
Dependent Claim
23 words
An apparatus as in claim 1, further including a document feeding means for discharging a document from said platen into said catch tray.
Claim 4
Dependent Claim
41 words
An apparatus as in claim 1, further including a sheet supporting tray supported by said support member whereby both said support member and said tray can move downwardly in response to the urging of an object placed on said viewing platen.
Claim 5
Dependent Claim
40 words
An apparatus as in claim 2, further including a supporting tray supported by said support member whereby both said support member and said tray can move downwardly in response to the urging of an object placed on said viewing platen.
