Abstract
Abstract A charge recording and reproducing device is constituted by a transfer device which transfers a film shaped recording medium from one to other side, a recording head adapted to form an electrostatic latent image from an image formed on the recording medium, an eraser for erasing the electrostatic latent image, a developing apparatus for developing the electrostatic latent image, and a reading device for reading the developed image.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
163 words
An image pick-up apparatus comprising: transfer means for transferring a recording medium in a downstream direction from one side of the pick-up apparatus to the other side of the apparatus; a recording head for forming an electrostatic latent image on said recording medium from a two dimensional projected image focused on the head, said recording head comprising a lamination of a transparent electrode and a layer of photoconductive material; projecting means for forming a two dimensional projected image from optical information of an object on said recording head; erasing means positioned on an upstream side of said recording head for erasing said electrostatic latent image; developing means positioned on a downstream side of said recording head for developing said electrostatic latent image, said developing means including toner applying means; and developed image reading means located on a downstream side of said developing means for reading said developed image, said reading means having noise eliminating means for removing particle noise generated by toner particles.
Claim 2
Dependent Claim
163 words
An image pick-up apparatus comprising: transfer means for transferring a recording medium in a downstream direction from one side of the pick-up apparatus to the other side of the apparatus; a recording head for forming an electrostatic latent image on said recording medium from a two dimensional projected image focused on the head, said recording head comprising a lamination of a transparent electrode and a layer of photoconductive material; projecting means for forming a two dimensional projected image from optical information of an object on said recording head; erasing means positioned on an upstream side of said recording head for erasing said electrostatic latent image; developing means positioned on a downstream side of said recording head for developing said electrostatic latent image, said developing means including toner applying means; and developed image reading means located on a downstream side of said developing means for reading said developed image, said reading means having noise eliminating means for removing particle noise generated by toner particles.
Claim 3
Dependent Claim
85 words
The apparatus according to claim 1, wherein said recording medium comprises an electrode acting as a light reflection layer, said lamination being positioned on a side of said recording medium facing said projecting means system, and wherein said reading means comprises a source of light; a light beam splitter which splits a portion of light emitted from said source of light, such portion being reflected by said light reflecting layer an then transmitted through said developed image; and a detector for detecting said transmitted light.
Claim 4
Dependent Claim
20 words
The apparatus according to claim 1, wherein said noise eliminating means comprises a space filter having a Fourier transforming function.
