Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 225 words
A recordable reader printer comprising: a scanner for optically scanning each of a plurality of documents and producing document image information for the images of said individual documents; means for producing retrieval code information respectively corresponding to said documents; a recording/reproducing device including means for recording in a recording medium the document image information and retrieval code information corresponding to said documents respectively from said scanner and said retrieval code information producing means and a means for reproducing the recorded information from said recording medium; means for inputting a retrieval code information corresponding to desired one of said image information for said documents; means for detecting from said recording medium a document image information corresponding to the retrieval code information inputted by means of said retrieval code information input means and giving said recording/reproducing device a command for reproduction to read out the detected document image information from said recording medium; and an electrographic printer including a means for converting at least the document image information reproduced by said recording/reproducing device into an optical image corresponding to the image of said document and a means for converting the optical image into a printed image; said recording/reproducing device including means for reproducing the document image information and corresponding retrieval code information immediately when said information is recorded and supplying said reproduced information to said electrographic printer.
Claim 2
Dependent Claim 225 words
A recordable reader printer comprising: a scanner for optically scanning each of a plurality of documents and producing document image information for the images of said individual documents; means for producing retrieval code information respectively corresponding to said documents; a recording/reproducing device including means for recording in a recording medium the document image information and retrieval code information corresponding to said documents respectively from said scanner and said retrieval code information producing means and a means for reproducing the recorded information from said recording medium; means for inputting a retrieval code information corresponding to desired one of said image information for said documents; means for detecting from said recording medium a document image information corresponding to the retrieval code information inputted by means of said retrieval code information input means and giving said recording/reproducing device a command for reproduction to read out the detected document image information from said recording medium; and an electrographic printer including a means for converting at least the document image information reproduced by said recording/reproducing device into an optical image corresponding to the image of said document and a means for converting the optical image into a printed image; said recording/reproducing device including means for reproducing the document image information and corresponding retrieval code information immediately when said information is recorded and supplying said reproduced information to said electrographic printer.
Claim 3
Dependent Claim 49 words
A recordable reader printer according to claim 1, wherein said scanner is composed of a light source to illuminate the document, and an image pickup element receiving a reflected light from the illuminated document and converting said light into a video signal corresponding to the image of said document.
Claim 4
Dependent Claim 56 words
A recordable reader printer according to claim 1, wherein said recording/reproducing device is formed of a video tape recorder including a recording magnetic head for recording the document image information from said scanner in said recording medium and a reproducing magnetic head adjacent to said recording magnetic head, whereby the recorded document image information is reproduced.
Claim 5
Dependent Claim 42 words
A recordable reader printer according to claim 1, 2 or 3, wherein said document image converting means of said electrographic printer is formed of an optical fiber cathode-ray tube to which the reproduced document image information from said recording/reproducing device is supplied.
Claim 6
Dependent Claim 82 words
A recordable reader printer according to claim 1, 2 or 3, wherein said electrographic printer includes a rotatable photoconductive drum, a first charger to charge said photoconductive drum, an exposure means for forming an electrostatic latent image corresponding to said optical image on the surface of said charged photoconductive drum, a developer to develop the electrostatic latent image into a toner image, a transfer means for transferring the toner image to a sheet, and a fixer to fix the transferred toner image.
Claim 7
Dependent Claim 44 words
A recordable reader printer according to claim 1, 2 or 3, wherein said recording/reproducing device is formed of a video tape recorder using an endless magnetic tape for said recording medium and performing recording and reproducing operations by means of a combined-use magnetic head.
