    The invention relates to a device for recording characters on a matrix indicator and can be used in devices for displaying information from a computer. A device for generating characters on a matrix indicator, comprising a character generator connected to input buses associated with a decoder and a buffer memory unit, a clock generator associated with a clock counter, a column counter of characters, an adder, whose outputs are connected to the generator: characters, a group of elements AND and a trigger 1 .. A disadvantage of the known devices is the impossibility of outputting oblique characters to a recording sign printing device. The aim of the invention is to expand the field of application of the device by presenting oblique signs recorded on matrix indicators. The goal is achieved by the fact that the device consists of a string of characters, the output of which is connected to the control inputs of the buffer memory block, the outputs of which are connected to one of the inputs of the elements and the first group, the other inputs of which are connected to one of the outputs counter rows of characters connected to the input of the counter columns of characters whose outputs are connected to one of the inputs of the adder, the other inputs of which are connected to the output elements And the second group, the first inputs of which are connected to the output the second trigger, the second inputs - with the output of the clock counter, connected to the input of the character row counter, the input of which is connected to the clock generator, and the inputs of the second trigger are connected to the decoder. FIG. 1 shows the logical formation of the sign; FIG. 2, a raster of a font pattern with a normal font; in fig. 3 - the same, with an oblique font. A device for generating characters behind the matrix indicator comprises a Character Generator 1 connected to the input buses 2 connected to the decoder 3 (FIG. 1). The character generator 1 is connected to the buffer storage unit 4. A 5 clock generator is associated with a 6 clock counter. The counter of 7 columns of characters is connected to the adder 8, the output of KOToijorb is connected to the generator of characters 1. Block 4 of the buffer memory is connected to one of the inputs of elements AND of the first group 9, One of the cy cytopa.8 inputs is connected to the counter 7 columns of characters, and the other - with the output of elements AND of the second group 10. The second inputs of the elements AND of the first group 9 are connected to the output of trigger 11, the output of which is connected to the input of the counter 7 columns of characters. The inputs of the decoder 3 are connected to the outputs of the trigger 12, the input of which is connected to the inputs of elements AND of the second group 10. To the control inputs of the block 4 of the buffer memory there is an output of 13 character rows, to the output of which trigger 11 and a column of characters are connected. The inputs of the row of strings are connected to the counter of b cycles, the generator of cycles and to the inputs of elements AND of the second group 10. The output of the counter b of cycles is connected to the inputs of elements AND of the second group 10;
    The device works as follows.
    In the proposed example, a matrix indicator is considered, made in the form of a mosaic printing mechanism and having seven consecutive recording elements arranged one above the other, which can be put into operation separately, or all together, i.e. parallel in any combination, and record the dot images of characters on the carrier (Fig. 2 and 3).
    The binary is coded and fed through the input buses 2 by the decoding information Cipher Vi etliipa Tope of characters 1 and is converted into a mosaic 4 Astra into a form similar to the recorded sign. The character geyutor 1 is controlled by a counter of 7 columns of characters. At the same time, the decoder of the columns inside the gyne; the ratios of characters are wired and cause the separate columns of this mosaic raster from the character generator 1 and the read control bits through the amplification cascade are parallel to the mosaic printing unit.
    From the mosaic print feed control unit; its mechanism receives a signal, which in the generator of 5 cycles is further divided into supporters. These passwords are controlled with a single 6 clock cycle and a counter of 13 lines of characters which outputs successive transmission cycles for the elements of the buffer memory unit 4. In addition, the outputs of the 6 clock counter are connected via the inverting outputs of the element I to the inputs of the bits of the sum of the torus 8. Through the second inputs of the elements AND of the second group 10, the values of the counter 6 cycles are either inverted for the adder 8 or locked.
    in the normal recording mode, logical O occurs through the decoder 3 trigger 12 through the decoder 3 trigger 12 with the two stable states on elements of the second coded character coded by a given binary-coded character. Thus, the logical inputs 1 are fed to the corresponding inputs of the adder 8. At the open inputs of the adder 8, there is also a logical 1.
    Meanwhile, the counting value of 7 columns of characters is applied to the decoder of the columns of the character generator 1. The clock counter has no effect on the selection of columns by the character generator, so that during the cycle of the count cycle, the 6 clock cycles and 13 rows count the sign bits only inside this column. from the character generator 1 and transmitted to the buffer memory unit 4. .After such a looping cycle, the information by means of the trigger 11 from the buffer memory block 4 is output through the elements AND of the first group 9 during the clock signal applied to it to the gain stage of the mosaic writing block. In this case, a normal sign is recorded in the raster (Fig. 2).
    If it is required to reproduce, an oblique font, then another binary coded character through a decoder.
    3 switches trigger 12 to another position, so that logical 1 is now set at the corresponding inputs of elements AND of the second group 10. Thus, the output of the counter of 6 cycles is inverted before being fed to the corresponding inputs of the adder 8, so that the output values from 1 meter of cycles are fed further to the decoder stoppers of the generator of the sign 1 by minus the output values of the counter 7 columns of characters. This means that with further control of the clock signals of the block
    4 buffer following one after another, the columns are polled in the character generator 1 and transmitted to block 4 of the buffer memory. After each cycle of running around the counter b of clock cycles. As in normal font, the opening cycle of the AND element of the first group 9 is issued through the monostable trigger 11. At the same time, when recording on the recording medium, a raster sample is obtained with an inclined font (Fig. 3). The transfer output of the adder is associated with the output of the resolution of the character generator 1, so that when the adder 8 reaches a negative differential result: the character generator 1 is locked.
