Auxiliary platen cover

摘要

In copier/duplicators lamps provide high intensity illumination of a document at an exposure station, and an image of the illuminated document is processed and transferred to a copy sheet. The copier/duplicator can have a combination recirculating document feeder and document positioner located at a first position over the exposure station for delivery to the station of a document sheet to be copied. The feeder can be mounted for movement to a second position spaced from the exposure station so that books or other documents can be manually placed directly on the exposure station. When the feeder is in its second position it is desirable to shield the machine operator from such high intensity illumination. For this purpose, an auxiliary cover is movable between a storage position adjacent the exposure station and a second position over the exposure station. Sheet guide members on the auxiliary cover are located relative to the document positioner so that when the positioner is in its position over the exposure station and the cover is in its storage position adjacent the exposure station the guide members are effective to guide a sheet into the document positioner.
