Abstract
A light image storing and reproducing device for storage and reproduction of original images comprises an information storage medium including a member having a photoconductive substance and an electrochromic substance, said member being supported between electrodes, original image projecting means for projecting an original image on said information storage medium, illuminating means for illuminating the surface of said information storage medium, and voltage applying means for applying a voltage of a prescribed polarity and a voltage of a reverse polarity interchangeably between the electrodes of the information storage medium.
Claims9
A device for storing and reproducing light images of original images comprising:
- a plurality of information storage mediums, each including a member having a photoconductive substance and an electrochromic substance and being supported between electrodes;
- original image projecting means for projecting original images on said information storage mediums;
- a plurality of voltage applying means for applying a voltage of one polarity and a voltage of a reverse polarity interchangeably across the electrodes of respective information storage mediums, wherein information images corresponding to projected original images are formed on said storage mediums when said one polarity is applied thereto, and said information images are stored thereon until erased by applying said reverse polarity thereto;
- a photosensitive member;
- and
- means for forming a composite image on said photosensitive member, said image forming means including means for illuminating said mediums and means for projecting said stored images of said mediums in superimposed form on said photosensitive member.
An apparatus for storing and reproducing light images of original images comprising:
- an information storage medium including a member comprising a photoconductive substance and an electrochromic substance, said member being supported between a pair of electrodes;
- a photosensitive member;
- means for supporting an original;
- projecting means having a first optical path for projecting an image of the original onto said information storage medium, a second optical path for projecting an image of the original onto said photosensitive member, and a third optical path for projecting an image from said information storage medium onto said photosenstive member;
- means for separating color images of the original for projection along said optical paths;
- and
- means for reproducing images projected on said photosensitive member.
