Abstract

The text of any documents, e.g. books, newspapers, typewritten pages, is reprographically converter into a new text in accordance with any kind, volume and sequence of selected text parts. The new text contains a shortened text, or parts of the text of the original document (2), and/or other different contents. Narrow surface elements (10) whose height is adjustable to the respective line, and whose width is adjustable down to a single character, are selected from any parts of the document and placed behind each other as often as required, beginning from any point. They are scanned, converted into a matrix and then read out in the order of their scanning, forming a new text reprographically reproduced on paper or made visible in any way.

Description

Device for reprographic text reduction

The invention relates to a device for reprographic text reduction, that of any information templates, e.g. books, magazines, typewriter pages, Any line-high or narrow, selected according to type, scope and order Reprographically converts text parts subdivided into a new text, an abbreviated content or partial content of the text of the information template and / or Contains different content.

The invention makes it possible to create extensive information templates from the texts the essentials on a case-by-case basis, with or without reformulation with what is present in the text Create and fix vocabulary, summaries. This will make the so far Handwritten or typed text excerpts, text transformations from scripts including how they deal with scientific, technical and other problems are often necessary, made much more time-saving and effortless.

When working on solving technical, scientific or other Problems, the processor relies more or less on relevant existing, mostly printed, handwritten or typewritten in magazines, books or scripts available results from which he more or less for his own collection of material comprehensive information that is important for his specific task, or by typing, sometimes with simultaneous reshaping. In the same way, specially oriented abstracts of longer papers are made or the important information copied page by page. The on Text reductions operated in these ways are time consuming and energy consuming.

It is true that facilities are known that provide a convenient and arbitrary sat Make it possible to transform texts, but they require that at least once Texts are entered by hand into the otherwise complex devices via keyboards and can be stored appropriately.

will. Such devices are largely used in preparation for production he prints information. You are not in favor of the solution at hand suitable. There are also devices known to use printed characters, primarily digits, allow optical or magnetic scanning and processing. They demand however, a specially prescribed character shape and size as well as a precisely defined one Position on forms such as checks or the like.

The invention is based on the task of writing by hand or by machine Any reduction required for task-related summaries or the like of texts that appear in magazines, books or typed information present to simplify with a device in which by scanning during a simply overriding arbitrarily selected, line-high text parts of an information template with a scanning head these text parts reprographically, in the order of their scanning, implemented legibly as a coherent new text on a suitable base and / or stored readable on a screen. This will A time- and energy-saving, substantial text reduction is achieved within wide limits.

This object is achieved according to the invention in that line height and up to character width surface elements of text lines of any printed, machine- or handwritten information templates, e.g. books, magazines, typewriter pages, Any number of times and starting from any selected positions, in any reading direction often lined up to be scanned in any way, the image of each scanned surface element rasterized in any way, in any way in a converted to digitally storable, digital bit matrix corresponding to the image content after which, with or without digital storage, the text parts in the order their scanning coherently as a new text reprographically in any way and / any Arrangement on a base legibly fixed and / or visibly displayed.

The advantages that can be achieved with the invention are that from Any and any printed texts from information templates templates of any scope, only those parts of the text that are of interest to a particular question, directly and / or reformulating with the help of the printed vocabulary, Quickly and effortlessly to an abbreviated new text that is legible on a surface is fixed, can be put together, saving time, manpower and space can be saved to a considerable extent.

An embodiment of the invention is shown in the drawing and is described in more detail below.

FIG. 1 shows the device for reprographic text reduction in schematic form Depiction.

On a base plate 1 for the support of the information template to be scanned 2 is in a housing with the stand 3, containing the optics 4 and a photocell grid plate 5, buffer storage 6 and incandescent lamp 7 permanently installed. The optics 4 is flexible about a Image conductor 8 is connected to scanning head 9, which rests on information template 2. It contains the rectangular surface element 10 which scans the text line and which is used for delivery of the storage pulse in the path scanning required path wheels 11 and for convenient guidance the handle 12. The surface element 10 is through the light bulb 7 illuminated via branched off fibers of the image guide 8 that work as light guides. The photocell grid plate 5 consists of so many individual small square ones Photo elements that the image of the scanned surface element 10 for an easily readable Playback is resolved satisfactorily, e.g. corresponding to image points of 0.1 x 0.1 mm. In the device shown, every small photo element is the photocell grid plate 5 hard-wired to an assigned digital memory cell of the digital buffer memory 6. The latter is connected to the digital main memory 13 in a known die. For the operation and control of all processes, such as data traffic, clocking, power supply, is used by the central control unit 14. The stored new text is transmitted via the central Control unit 14 with the printer 15 operating according to the matrix method, depending on Instruction, output line by line or line block by line. In the example shown, plus a line printer with a matrix of 7 x 9 9 points and electrostatic writing system.

Alternatively, a second text is available for the output of the new text in FIG Arrangement drawn. Instead of the printer 15, the new text is output here the digital main memory 13 via the central control unit 14 on the fiber optic Screen of the cathode ray tube 16 imaged electron-optically and stored. It can be parallax-free on the pressed-on photographic paper 17 in the registration device 18 be fixed.

The functional sequence is as follows: The scanning head hits the line of text the information template 2 placed for a scanning process, then transmits the Image guide 8 the image of the scanned surface element 10 to the optics 4, which it enlarges on the photocell grid plate 5 shows where the numerous small black and white sensitive photo elements convert the picture into a digital one corresponding to the picture content Transform bit matrix. After each movement of the scanning head 9 in the reading direction a surface element width causes a pulse of the way wheel 11 that the current The content of the digital buffer memory 6 is transferred to the digital main memory 13 and the bit matrix corresponding to the image of the newly scanned surface element in the digital buffer memory 6 is stored. This process is repeated continuously, while the scanning head 9 at any point in the information template 2 is placed and moved in the reading direction. Is the scanning finished or a Filling of the digital main memory 13 is sinalized, the stored therein is new text printed out on roll paper after pressing a button, what is program-controlled and ordered line by line by the central control unit 14 from the electrostatic working line printer 15 is made. Since this the print lines by assembling of dots in a dot matrix is shown with a higher-resolution photocell grid plate 5 by program an output evaluation for the individual matrix points of each made by the printer 15 to be outputted characters. But you can also for simplification the individual photo elements of the photocell grid plate 5 in number and arrangement make equal to the dot matrix of the printer 15. With the one in Figure 1 for the output of the new alternative solution shown in the new text, in which this is made visible on the cathode ray tube 16, causes a larger Resolution of the photocell grid plate 5 that the lines shown with a matrix increased score on the screen, which improves readability.
