The invention relates to automation and computer technology and can be used to record information in graphical form. A bipolar signal recorder is known, which contains a register, a comparison circuit, a counter, a control device, a switch of poles, and a tape drive mechanism C1. The disadvantage of this device is low throughput, since only one K-bit value is recorded on a data carrier for each sweep cycle. dnogo code recorded in the register. The closest in technical essence. The invention is a device for recording information, containing n comparison circuits connected to a register and a luminance modulator counter, connected to comparison circuits and tape recorders. a mechanism which, through the control device, is connected to the counter K-bwi 2 3. A disadvantage of the known device is the small throughput method. due to insufficient recording density: digital information per unit area of the information carrier, since the media used (;; form, for example, electrothermal paper, provide registration of 3-4 processes. The invention aims to increase the throughput of the device This goal is achieved by the fact that in a device for recording information, containing a receiver of information, the input of which is the input of the device, and the outputs are connected to the first inputs of the corresponding elements of the comparison, the modulator is and a tape mechanism, the outputs of which are connected to the corresponding inputs of the control unit, the first and second outputs of which are connected to the corresponding inputs of the counter, the first output of the control unit is connected to the control input to the input of the information receiver, the third output of the control unit is the output of the device, the output of the counter connected to the second M inputs of the comparison elements, entered the first and second OR elements, AND elements and code converters, the output of the comparison elements is connected to the first inputs of the corresponding Their elements are AND to cooTBeTCTBjTMmiM: the inputs of the first element OR, the output of which is connected to the first input of the modulus of brightness, one output. The tape drive mechanism is connected to the input of the second element OR and through the corresponding code converters to the second inputs of the elements AND, the outputs of the elements AND connected to the corresponding other inputs of the second OR element, the output of which is connected to the second input of the luminance modulator, the output of which is connected to the input of the tape drive mechanism. FIG. 1 shows a functional diagram of the device for recording information; in fig. 2 - examples of recording information. The circuit contains information receiver 1 (PN), comparison elements 2-4, code converters 5-7, elements AND 8-10, first and second elements OR 11 and 12, luminance modulator 13, tape drive mechanism 14, control unit 15, counter 16, IT output and input 18 of the device. The device works as follows. In the tape drive mechanism 14 (LPM), the abscissa axis sweep (X axis) is performed by continuous or discrete movement of the carrier (for example, electrothermal paper), and the ordinate axis (Y axis) is carried out, for example, by means of a linearly displaced writing element. Block 15. control (CU) generates commands necessary for control of the electron. Registrar circuit. The command from the CU 15, coming through the output 17 to the external device, serves as a request for issuance from the external device. The input to PI 1 is through input 18 code words (K-bit codes) corresponding to the next values of the ordinates of the output information. At the command of the LML 14 about the end of the sweep along the Y axis, the information carrier is shifted by one increment along the X axis, and the control unit 15 generates a pulse that sets the counter 16 to the zero state and rewrites the input code words in PI 1. Each code word originating from PI A corresponding comparison element characterizes certain recorded information. The impulse with LPM 14V corresponding to the beginning of the sweep of the U-axis enters the BU 15, which from this moment begins to generate counting pulses providing the counter 16. The impulse of the beginning of the sweep along the U-axis (zero-count impulse) also goes to the OR 12 element and the corresponding converters 5-7, prohibiting or permitting the passage of pulses through the elements And 8-10. At the moment of equality of the code at the output of the counter 16 and the code words stored in PI 1, the elements 2-4 are triggered.

comparisons, the output pulses of which are fed to the element OR None through the elements AND 8-10 to the element OR 12. So the converter 5, made in the form of a counter, the output of the higher bit of which is connected to the element AND 8, can, for example, during four sweep cycles on the Y axis to allow the passage of pulses on. . the element OR 12 and for four cycles prohibit the passage of these pulses through the element AND 8. The pulses from the output of the IL 11 and 12 elements are fed to the input of the luminance modulator 13, the latter providing registration on the information carrier and the pulses coming from the OR 11 V element in the form of points of medium brightness, and pulses arriving from the element OR 12 in the form of points of increased brightness, i.e. dots have two distinct gradations of brightness.

Thus, the output impulse of each comparison element is recorded on the information carrier in the form of medium brightness points, if it arrives at the brightness modulator through the OR element 11 or as a high brightness point, if it arrives at the brightness modulator 13 through the OR element 11 and through the element OR 12. For one cycle of ra: the inverters on the Y axis, a zero reference point is recorded on the information carrier and the ordinates of codeword values in the form of distances corresponding to points to zero reference point. Over m scanning cycles along the Y axis, the digital information display is presented in the form of lines formed by dots and differing

from each other, since they have the form defined by the modifier along the X axis. The maximum number of lines of recorded digital information that can be recorded on the record carrier

given width is determined by the formula

where H is the Oirin of the recording medium; сГ - width of the applied line. For example, in case of a recording media carrier width H 300 mm and a width of 1 mm applied to the line, the maximum number of recorded curves is K / 5 - 10) XI 60 - 30. Whether scientific research institutes may be the most spacing). So converter, codes 5; provides registration of digital. Information in the form of LINI.Y, cpc 1tsey. for example, from a series of middle and high sections: - examples of the recording are shown in FIG. 2; (segments having

The increase in the number of recorded curves from 3-4 to 30-60 provides an increase in throughput of the device.
