Abstract
Digitizing apparatus for reproducing information from an image-bearing member, said apparatus including a wand removably mounted on a base station. The wand is adapted for independent operation to manually scan said image-bearing member or the wand can be secured to the base station for automatically scanning said image-bearing member.
Claims2
A digitizer adapted to generate detectable electrical signals corresponding to an image on an image-bearing member comprising:
- an elongated digitizing wand, said wand sized and shaped for portable use and adapted to be manually moved across and thereby scan an image-bearing member;
- said wand including a photoresponsive array of light sensitive elements, each light sensitive element including at least one layer of amorphous silicon alloy material including hydrogen and fluorine;
- each light sensitive element adapted to receive light from a corresponding small area portion of said image-bearing member and generate a detectable signal representative of the amount of received light;
- a base station, said station including:
- means for receiving said image-bearing member;
- means for removably supporting said portable wand;
- and drive means for providing relative motion between said member and said wand at a preselected rate of speed, whereby said digitizer is adapted to manually as well as automatically scan an image-bearing member.
A digitizer adapted to generate detectable electrical signals corresponding to an image on an image-bearing member comprising:
- an elongated digitizing wand, said wand sized and shaped for portable use and adapted to be manually moved across and thereby scan an image-bearing member;
- said wand including a photoresponsive array of light sensitive elements, each light sensitive element including at least one layer of amorphous silicon alloy semiconductor material including hydrogen, fluorine and a band gap modifying element;
- said modifying element adapted to adjust the photoresponse of said elements to specific wavelengths of incident radiation;
- each light sensitive element adapted to receive light from a corresponding small area portion of said image-bearing member and generate a detectable signal representative of the amount of received light;
- a base station, said station including:
- means for receiving said image-bearing member;
- means for removably supporting said portable wand;
- and drive means for providing relative motion between said member and said wand at a preselected rate of speed, whereby said digitizer is adapted to manually as well as automatically scan an image-bearing member.
