The drawing shows a structural electrical circuit of the proposed device. A device for generating marks on the screen of a cathode ray tube contains a generator of I clock pulses, a counter of 2 raster pulses, a counter of 3 characters, a first digital-to-analog converter 4, a first amplifier 5, a row input 6 of a deflection system of a cathode ray tube, a counter of 8 printed lines , second digital-to-analog converter 9, second amplifier 10, personnel input 11 of a deflection system of a cathode ray tube, character generator 12, shift register 13, video amplifier 14, cathode ray tube 15 , a memory unit 16, a control unit 17, an address register 18, a shift pulse generation unit 19, an address selection unit 20 and a shift register control unit 21. The device works as follows. The clock pulses of the clock pulse generator 1 are counted in a counter of 2 raster points. One clock signal corresponds to one raster point. The dots counter counts eight horizontal raster points of the microbutton area. When the counter reaches the raster points of the final value, the 3-digit counter is incremented by the advance signal applied to the input. The contents of the raster point and character counter are converted in the first digital-to-analog converter 4 into an analog signal, which in the first amplifier 5 is converted into the required deflection signal for horizontal scanning of the writing beam of the electron-beam tube 15. The 3-character counter counts 132 characters of the printed line. At the same time, it is used to measure the period of time required to return the writing beam to its original position. During the phase, the counter of 7 raster lines is turned on by the switching signal to the next position so that when the horizontal beam of the beam is located next to each other, the next raster line of the printed line is processed. When the score reaches the maximum of 7 raster lines, it returns to its initial state with a switching signal from the 3-digit counter, and the count of 8 printed lines increases by one. A count of 8 printed lines counts 64 printed lines and issues a output on the output that the end of the page is reached if the printed line counter does not return with the aid of an external control signal. The content of the 7 raster lines counter and the 8 printed lines counter gives, through the second digital-to-analog converter 9 and the second amplifier 10, a signal to the code input 11 of the deflection system of the electron-beam tube 15. When the micro-signals are imaged through the shift pulse shaping unit 19 for eight cycles, one pulse is output to the block 16 memory, made in the form of a shift register. Information from the output of block 16 is transmitted to control block 17 and back to the input of block 16, since the selected reproduction principle requires multiple information. The selected word, in accordance with the rasterization of the area of the mark, consists of a maximum of 12x8 bits, from which an image of a word of 8 bits is selected through a selective address formed in block 20 and connected to the character generator 12. In the case of a microbase image, this selective address matches the address of the raster lines. The selected image of the word is recorded in parallel in the shift register 13 and calculated sequentially with the pulse repetition part of generator 1. This is due to the video signal being fed to video amplifier 14, where it is amplified and controls the intensity of the cathode ray pickup beam. the same stroke, but at changed intervals, in block 16, a new sign is generated, the selective address is changed to select a word, and a progress signal is output to the shift register 13. When depicting a microz aka, i.e. in the case of a logical L, a clock stf-nal generates a advance signal supplied from the output of the generator 1 through block 21 to the shift register 13. To depict small macrosignes with a logical O in both lower stages of the 2 raster points counter, a counting pulse is applied to block 21. In block 21, the pulse is converted into a progress signal, which is fed into shift register 13. When the image is large, the macroscancally produces the advance signal, 6. 6 which is fed to the shift register, all 32 cycles with a logical O at the output of the address register 18. The selective signal at the output of the address register 18 distinguishes between the image of microsnaps (logical L) and macrostars (logical 0), the selective signal at the other output of the address register 18 distinguishes both sizes of macrosnaps. The selective signals express the output values of the address register 18, which is set via the control unit 17 using external control signals. At the image of microsigns, the formation of selective addresses occurs, and a logical L at the output of the address register 18 is connected with the readings of counters 2 and 3. Block 16, written as a shift register, works with different shift strokes, depending on the selected font size. When the starting address recorded in address register 18 is reached, a shift pulse is formed in block 19. When large macrosignals are represented, the switching signal of all 16 microsign lengths is generated by connecting the readings of the count 3 and the signal from the output of the address register 18 in block 21. As a result, the output of block 21 produces a shift signal. When depicting different values of characters, in accordance with different line lengths, the shift pulse for large macro samples is supplied to the first three memory blocks of the memory block 16, made in the form of a shift register, for small macro signals, to the memory blocks from the first to the twelfth and for micro signals - to all blocks. In accordance with the described device action of the device, the information of the shift register 13 is multiple, therefore the information c, g. the output of block 16 is fed again to the input (for large macrosignals, to the input of the third memory block).
