Devices for displaying information are known. One of the known devices comprises first and second registers connected to each other and to a control unit connected to the printing unit and the perforator.

The second of the known devices contains the first, second and third registers interconnected with each other and with the control unit, three decoders, through two of which the registers are connected to the printing unit and the perforator.

the first and second counters, the first decoder, the printing unit, the perforator and the address generation unit. A disadvantage of the known devices is

the speed of parallel output of information to print and perforation is low, and the printing speed is significantly lower than the speed of the punch.

The aim of the invention is to increase

device performance to display information.

The goal is achieved by the fact that the device for outputting information contains the third and fourth decoders and the third counter, with one input of the third decoder connected to the output of the first counter and one of the inputs of the address generation unit, the other input connected to the output of the third counter, whose inputs are connected to the outputs block

control and to the input of the first counter, each input of the address generation unit and the input of the fourth decoder, the output of which is connected to the input of the control unit. FIG. 1 shows a block diagram of a device.

A device for outputting information contains an accumulator 1, an address generation block 2, a first register 3, a second register 4, a third

register 5, fourth register 6, first counter 7, printing unit 8, second counter 9, third counter 10, first decoder 11, second one: ifrator 12, third decoder 3, fourth de-diffrator 14, block 15 of comparison, perforator 16 and block 17 controls with inputs 18-25 and outputs 26--42 (supervisors of the inputs and outputs of control unit 17. The theory epovets the designation of diagrams of signals on the diagram of Fig. 2).

Drive 1, iredpazpachepyy for storage /; r-bit of the printer for the printing unit 8, output by output 35 of the block 17 yiTralepi, the inputs of the first and second registers 3, 4 by the output of the fourth regpetr 6, the address of the packet address that inputs are connected to the output 27 of the control unit 17 and the address generation unit .2, the inputs of which are subsequently connected to the output 34 and the input 24 of the control unit 17, the output of the first decoder 11, the inputs of the first and third registers 3, 5, the outputs of the first and third counters 7, 10 and the inputs second, third and fourth decoders 12, 13, 14.

The second register, occasionally for snoring the character code read from accumulator 1, is connected to output 28 of control unit 17 and one of the inputs of comparative unit 15, to another input of which the output of second counter 9, which is used to calculate clock pulses, is connected to another input and input of first decryptor 11. a print generator and one connected to the outputs 31 and 40 of the block 17 are equipped with an inverter, moreover, the output of the comparison block 15 is connected to the input of the third register 5, which fixes the sign of printing. The outputs of the non-operating unit 8 are connected to the inputs 19, 20 of the control unit 17, and its input to the output of the third register 5, the inputs of which are connected to the outputs 29, 36, 39 and the input 23 of the unit

17 and the output of the second decoder 12, designed to isolate the zero state of the first counter 7, the inputs of which are connected to the outputs 26, 32, 37 of the control unit 17 and the third counter 10, which is the driver of the addresses that are used to read characters from the parallelo 1 after print line, and the inputs of the third counter 10 are connected to the outputs 33, 38 of the control unit 17. The perforator 16 is connected to the inputs 21, 22 of the control unit 17 and the output of the first register 3, the input of which is connected to the output of the third decoder 13.

The device for outputting information operates as follows.

The information, but it goes to the output from the digital computer, enters the drive 1. When the volume of information in the drive 1 reaches the volume of the line, determined by the width of the printing unit 8 (tons of characters), from the digital input to

18 of control unit 17, a start signal is received, which starts the operation of the device.

With the arrival of the printing unit 8 in the unit

17 control from input 19 of the channel, the beginning of the first counter 7 and the third counter 10, the third register 5, the first register 3 and the second counter 9 are reset to zero by the signals from the outputs 26, 29, 30 and 31, respectively, along the signals from the outputs 32 and 33, the co-instant m is written to the first counter 7 and the third counter 10. The successive signals from the outputs 27, 34, 28, 35, 36, 37 from the control block 17 will set the fourth register 6 to zero; enter the contents of the first counter 7 into the fourth register 6, since at the given moment of time from the first decoder

11 an address signal will be given to address generation unit 2; setting to zero the second register 4; refer to drive 1 to read the character code from tip 1 to the second register 4 and to the first register 3,

This only registers the first codes of the first counter 7 and the third counter 10 into the first register 3 or when the second counter 9 goes to the (n-1) -th state (where n is the number of characters on the printing wheel) when the first register 3 receives the enable signal from the third decoder 13 or from the first decoder 11; take a look at the comparison of the code of the second register 4 with the code of the second counter 9 and the third

register 5, and the recording of the comparison results in the bits of the third register 5 is switched by the output signals of the second decoder 12 (when the nerve is accessed by the drive 1, the comparison result is recorded in the first

bit of the third register 5, with the second - in the second, and so on, until the m addressing the drive 1, when the th (the result of the comparison is recorded in the "th-th bit of the third register 5; subtract one from the first counter 7 .

The generation cycle of the signals from the outputs 27, 34, 28, 35, 36, 37 by the control unit 17 is repeated once to the zero state of the first counter 7, in which the signal from the second decoder 12 to the control unit 17

the input 23, indicating the end of calls to the drive 1 and the end of the comparison of the read codes with the code of the first character of the print wheel, recorded in the second counter 9.

Upon receipt of the synchronization signal from input unit 8 at input 20, control unit 17 generates a print signal from output 39, but which polls the bits of the third register 5 and prints the character currently opposite the printing hammers.

When the first character of the printing wheel is printed, the third register 5 is reset to zero by the signal from output 29, and one is added to the second counter 9 by the signal from output 40, resulting in the second counter 9 setting the code of the next printing wheel symbol. By the signal from output 32 to the first counter 7 again

the constant t is written and the same again describes the generation of signals from outputs 27, 34, 28, 35, 36, 37 described by BiiUiie, followed by the printing of the second wheel-hitting symbol, after which the signal from output 29 removes the third register 5 into a bullet and from output 40 to the second counter 9, a unit is added, etc. When the second character of the print wheel is set in the second counter 9, the print cycle will end with printing this character and the control unit 17 will stop issuing the signal from the input 24 of the first decoder 11 signals from outputs 32, 28, 36, 37, 39, 31, 40.

The punching cycle begins at the same time as the line printing cycle.

By the start of the perforation signal from the input 21, coming from the perforator 16, the control unit 17 generates a perforation signal at the output 41, which polls the bits of the first register 3 and perforates the symbol. The perforation signal from output 41 ends at the end of perforation from input 22, which enters control block 17 from perforator 16, after which one is subtracted from output of third counter 10 by signal from output 38, and the first register 3 is reset to zero from output 30. If the printing line is still non-final, the character in the first register 3 of accumulator 1 is rewritten if the contents of the first counter 7 coincide with the contents of the third counter 10, followed by punching this character and subtracting the unit from the content of the third counter 10.

Since the start of perforation signals from input 21 follow less frequently than sync pulses from input 20, during the time of printing a full line consisting of m characters, a number of k characters (k) will be opened. At the end of the print cycle from the output of the first decoder And the address generation unit 2 receives a signal allowing the contents of the third counter 10 to be rewritten into the fourth register 6 and at the same time prohibiting the rewriting of the contents of the first counter 7 to the fourth register 6. After the full line has been printed together (t). Hierforadia (k symbol) control block 17 for perforation of each of the remaining - k

symbols gives cni rolls, respectively, from the outputs 27, 34, 35, 41, 38, 30. The perforation of the last m-th symbol is fixed by the signal from input 25, which enters the control unit 17 from the output of the fourth decryptor 14.

On the sigpal from output 25, the control unit 17 stops the generation of the Wiravlein signals and generates a request signal at the output 42 in the PVM for input to drive 1 of the next information for printing by the next line and parallel perforation.

The techno-eco-iomic effect of the invention is to maximize the speed capabilities of rotary hammers and printers while simultaneously outputting information from TsM.M.
