The movability of the matrix makes it possible that the optical system changing the light beam onto which the characters can be projected one after the other on the receiving / receiving tube. Can be brought through this arrangement point; the number of characters is achieved so that when the transition from one area of the matrix to the other is not restricted by the size of the character ring, no mechanical receiving surface of the receiving tube is restricted.

right lines or slots controlled. After the correct sequence of programming has reached this position in the area 32, the 5 is accomplished by the program counter 56. At the point of light on the screen in the area 33 of the end of each operation in the arithmetic unit, the screen is generated letters and the sum contained in the program counter 56 thus defines the position in the horizontal row and the newly formed sum is added over a device within this' Hache, in which the image of the address memory is stored in order to generate the next letter. Execute the signal from the OK operation in the pro picture tube 5 that is currently in progress and the voltages of the raster abbreviations. Each operation of the program kung are now given to the tube 7, which is contained in a command memory 57, to generate the instructions for the processing position from the image of the letter in the arithmetic unit determined with it. The extent of the movement processing of the data is given, for example that of the point of light is controlled by feedback. The memory content of the memory 24 is controlled by the flashlight, which works according to the zero principle and has to be transmitted to the coding device. In which the position counter 38 is served. This counts the on program, changes to the type number of steps in the movement of the light point are also carried out. For example, when setting one of the grid and thus gives the actual position of the newspaper, the first paragraph should be printed in thick font from betion of the light point. Corresponding signal to the 2 ° correct size, the second paragraph arithmetic unit, in which this signal with the desired - is compared in a smaller and thinner font and the rest of the light point position.

In the exemplary embodiment, the program depends to a considerable extent on the infollowing the transport gradually, with the amount of computing information on the data carrier from which works a signal through the buffer 29, the instructions are read. For example, if the entire memory content of the memory of the punched tape does not provide any information about the chers has been called up for a line of text and the 30 line length compensation is required, the program corresponding letters have been shown. of the arithmetic unit in a manner known per se with sol-Das Step signal is additionally provided by the control circuit 51 on the control circuits given the driver circuit 52, and one next to the width of each letter and the word film reel located button 53 scans their spaces of movement and add the line at a fitting and sends a signal to the control circuit 51, send position 35, when the margin adjustment is done this confirms that the film transport has been achieved.

The line spacing is controlled with such a device.

Another advantage given by the use of the cathode ray tube, which is achieved by a displacement of the cathode ray tube, consists of 0.5 mm on the film. This means that the definition that a normal letter is electrically distorted is compensated for by the incremental movement. At the end of the can to a modified letter in the next line, the film receives three steps, namely to receive an oblique letter for example. It borrowed 3mm in total, and the line shift of the can be stopped by electrical means above or below the scanning area on the tube, shifting half of the common base line, subtracting 0.5mm from film travel. 60 _S o that the mapping and setting mathematical

To increase the speed, each ring that contains a different type can be placed on the drum contain the most frequently used letters twice or three times. With a ring of 180 letters For example, the letter "e" can appear twelve times. If desired, the motor can be continuous driven so that the film is also continuously transported in the longitudinal direction, with a corresponding shift of the letter to be exposed on the cathode ray tube is achieved by providing an appropriate compensating deflection voltage. Thus, if the film moves upwards, the letters generated one after the other for a certain Line a compensation movement lengthways

Instead of using a single cathode ray tube, you can map the letters onto the film two tubes are also used, which have reduction lenses such that each tube

On the other hand, a single cathode ray tube can have two linear exposure zones on its screen have, with lenses arranged so that both the horizontal and the vertical Shift is performed to produce two end-to-end lines along the width of the film. This process of dividing lines can be continued if necessary.

This is because of this Such a photographic light composition has been achieved that when entering the data for the machine known (Computer Type Setting Conference characters of a line the arithmetic unit the country Proceedings, July 1964, London, Chapter 8, p. 212 the need for the characters themselves compared to the to 223), in which all characters on the image length are determined and from this the character and / or transducer of the pickup tube are mapped. The 45 word spacing is calculated. The object of the present invention is to accelerate the process to a metal perforated plate at a high operating speed without a large amount of space in which a small hole in the control and components is formed for each character. Ability to achieve by the image converter. Furthermore, a larger page is aimed for to select a certain 5 ° larger character capacity.
The above object is arranged according to the invention valley wires, which wires are achieved in that the pick-up tube can be subjected to a voltage suitable for the image that only has memory that is essentially assigned to the selected characters The entire area for generating the video signal is scanning electrons with a scanning movement of the 55 bar, the matrix is movable relative to a recording point, character image over which the character is also in a predetermined position with respect to the recording-arranged hole through the perforated plate that selected characters can be tapped and a corresponding video signal at Chen when it appears at the pickup point through one of the anode of the pickup tube from which the movement of the matrix can be detected.

As the selected character is only mapped onto the small part of the total area of the perforated plate from the total area of the image converter, what does it mean. Since the character matrix used has a maximum of 256 characters due to the size of the image converter times alone, the enlargement limited to the area can be carried out at the same time, and must be mapped onto the pickup tube, since the scanning after the mapping is carried out by a
