Contact Imaging Station

A contact imaging system for a dichroic copier utilizes a curved document platen to insure intimate contact between the document to be copied and a dichroic photoconductor.

A dichroic photoconductive belt 11 is advanced to a copy position. Document 13 is placed over platen 15 for a copy cycle. Pneumatic cylinders 17 are actuated driving platen 15 containing document 13 against thin film shield 19. Platen 15 is curved and consists of a flexible material thereby assuring intimate contact between document 13, thin film shield 19, and dichroic photoconductor belt 11. Thin film shield 19 is driven into intimate contact with dichroic photoconductor 11, which rests against fixedly mounted transparent backup plate 21. Light source 23 is turned on to effect a copy cycle. Pneumatic cylinders 17 are thereafter released and dichroic photoconductor belt 11 containing the document image is advanced for processing copies therefrom.
