The goal is achieved by the fact that the device for fixing and documenting time according to the author. St. No. 559213 entered a date switch, two control buttons and a date formation block connected via decoders with digital boards associated with its information inputs to the storage register outputs of the same name, the counting input with the calculated output of the command generation block, and information outputs with the corresponding date switch inputs connected by address inputs and information outputs respectively to the address outputs of the date shaping unit and information inputs of the typewriter interface unit, in addition Tel'nykh whose inputs coejjHneny with control buttons and adjusting the output is connected with the same input command generating unit to which connected and permitting the fixation prohibiting recording unit outputs increase reliability.

In this case, the date shaping unit contains scaling circuits, a single-vibrator, a D-flip-flop, a push button and:; which, both inputs are connected to the outputs of the storage register, and the output is connected to the control input of the D-flip-flop connected by its counting input with the same output a command generation unit, and an output with a single-vibrator input, the output of which is connected to the input of scaling circuits connected by another input of the fitting button with the output of the storage register, and information outputs with corresponding inputs of the decoders. FIG. 1 shows a schematic of a device for recording and documenting time; in fig. 2,3, 4 - yhe we block the formation of the date, the unit with the typewriter with a typewriter and block the formation of commands. The device for fixing and documenting the time contains a line of coded time signals of the primary clock 1, a block for selecting clock and pulses 2, a receiving register E, a decoder for board number 4, storage regist 5, a command generation unit 6, decoder for digit 7, digital board 8, switch 9 , reliability enhancement 10, interface unit with typewriter 11, typewriter 12, commit button 13, reset button 14, date button 15 date print button 16, date shaping unit 17, date switch 18, decoders 19 and digital display 20. Block pho Date shaping includes AND 21, D-flip-flop 22, one-shot 23, scaling circuits 24 and a push-button 25. The interface with the typewriter includes AND 26, two schemes OR 27 and 28, four single vibrators 29, 30 , 31, 32, trigger 33, counter 34, a decoder for the digit of the printed figure 35, a four-bit circuit OR 36 and a decoder 37. The command forming unit 6 contains three single-oscillators 38, 39, 40, three And 41, 4.2, 43, two circuits flip-flops 44 and 45, two six-bit circuits AND 46 and 47, and a six-bit pattern OR 48. The device works as follows. The input of the clock selection unit 2 from the primary clock 1 line receives coded time signals. The clock pulses from the output of block 2 are fed to the receive, register 3 and command generation unit 6. Fill register 3 information about the transmitted data, the digit to the information inputs of the storage register 5 and the reliability enhancement unit 10 ,. and the information on the number of the board goes to the decoder of the number of the board 4, from which to block 6 one of the six wires receives a pulse, the duration of which is equal to the duration of the pause between the sequences of pulses in line 1. . - h y - Block 6 in the current time indication mode generates a pulse on one of the shesrgi outputs of the decoder 4, which is fed to the switch 9. Switch 9, in accordance with the incoming pulse, connects to block 10 the outputs of four binary bits of the register 5 corresponding to the board number 3 digits received in the register. After this, block 6 generates a comparison command arriving at block 10. When the binary information arrives at block 10 from register 3 and from switch 9, the output of block 10 generates a lock-inhibit signal, which is fed to block 6 and to the interface block 11. This signal is removed after the match of the 6) matching blocks of 10 digits. Thus, the recording of new information in the storage register is made only when the change is made. of time. At the end of the recording in the register 5. the value of the next digit, in the absence of a signal - blocking lock by block 6, a counting pulse is output to the date shaping unit 17. With this pulse, the output of the driver 17 changes in the corresponding state of register 5 in the discharge of ten hours .. The outputs of register 5 and imager 17 through digital decoders 7 and 19 are connected to digital indicators 8 and 20, which display the current time and date in the usual digital form. When one of the three control buttons 13, 15, 16 is pressed, the interface unit 11 generates a latch command and in the absence of the block 10 output signal prohibiting latching, block 6 stops the generation of comparison commands and recording. In the storage register 5, the recorded before that, the time information and the time of pressing the button are recorded on the digital scoreboard. When you press the date stamp button, the block 6 connects the control inputs of the switch 9 to the same outputs of the interface unit 11. The interface unit 11 controls by alternate connection of the outputs of the date switch 18 to the form generator 17.- After the date printing ends, the interface unit 11 controls alternately connecting the inputs of switch 9 to the outputs of storage register 5. The connection speed is determined by the frequency of the typewriter sync signals. When you press the timeout, only six times are printed. The transition from the latching mode to the current time indication mode is performed automatically after the end of printing. When there is interference in the line or in the device operation, the command-fixation at. pressing one of the buttons 13, 15, 16 on the turn only after the end of the signal prohibiting latching at the output of block 10, setting the code of input 00 to D-flip-flop 22 for a ten-hour storage register 5 sets a sigdal logical unit. With the first counting pulse, the D-flip-flop is set to state 1. The single-oscillator 23 generates pulse-day, which converts the scaling circuits 24 to the next state. At the output of the scaling circuits, a signal is generated in binary code about the date value. To manually set the date, the pulse sequence with a frequency of 1/10 Hz is fed through the button 25 to the input of the scaling circuits 24. A counting impulse is formed after the end of the comparison and recording. And only in the absence of a signal, which stops fixing. The use of a counting pulse and the use of a D-flip-flop in block 17 exclude the possibility of forming a false signal day. When the button 15 is pressed, the one-shot 30 produces a pulse that sets the trigger 33 to state 1. A logic unit signal arrives at the input of circuit 26 and if there is no signal blocking latching on: the output of block 10 by each sync signal from the typewriter 12 at the output of circuit 26 a pulse is formed, changing the state of the counter 34. At the outputs of the decoder 35, pulses are alternately generated. The signals from the first six outputs control the operation of the date switch, and from the next six - the operation of the block 6. These signals to the inputs of the decoder 37 through the four-bit circuit OR information is received about the value of one of the twelve bits recorded in the storage register 5 and block 17. The pulse from the output of the circuit AND produces the resolution of the information transmitted to the input of the decoder 37. The output of the decoder 37 controls the typewriter . After printing all twelve bits of the signal from the thirteenth output of the decoder 37, the trigger 33 returns to its original state. At the output of the OR circuit 28, a reset signal is generated, which is used to transfer the line and return the typewriter carriage, as well as return the circuit to the current display mode. time .. When the button 16 is pressed, the pulse from the one-shot 29 in the counter 34 is set to the seventh state and only time is printed. When the button 13 is pressed, the one-shot 31 produces a pulse arriving through the circuit OR 27- to the block b. To digits
