The purpose of the invention is to improve the recording quality by eliminating ambiguity when using information.

The goal is achieved by introducing a second OR element, as well as serially connected code summing unit, an equivalence block and a pulse shaper, and the output of the AND element is connected to the luminance modulator via the second OR element, the second input of which is connected to the output of the pulse shaper, the inputs of the code summing unit are connected to the input data buses, the second input of the equivalence unit is connected to the input of the code reading unit, the output of the first converter is the time code the interval is connected to the second input of the pulse former.

FIG. 1 shows a block diagram of the device; in fig. 2 types of recorded information.

The device contains a generator of 1 pulses of pulses, a unit 2 for controlling an electric motor for moving a squeezing pin, an electric motor 3

the writing pin, the writing pin 4, the motor control unit 5 moving the recording medium, the motor 6 moving the recording medium, the recording medium 7, recording amplifier 8, block 9 in the recording area, the first converter code - time interval 10, the second converter code - time interval 11, block subtraction unit 12, recording area width encoder 13, trigger 14, logic element OR 15, logic element AND 16, brightness modulator 17, second logic element OR 18, code summation unit 19, equivalence unit 20 , The pulse generator 21 and the input data lines 22 and 23.

The device works as follows.

The pulses of the clock pulse generator 1 are fed to the motor control unit 2 of the writing pin movement motor, a pulse voltage at the output of which ensures the shaft of the writing pin moving motor 3 by an angle dependent on the number of pulses from the generator 1. The angle of rotation of the shaft of the electric motor 3 by mechanical transmission is converted into the linear movement of the recording pin 4 across the recording medium 7 from the initial state, with this, the recording pin 4 is moving forward and on the recording medium and information is applied. When the writing pin 4 reaches the end position (opposite to the initial), the pulse from the output of the control unit 2 starts the control unit 5 of the control motor for moving the recording medium, which generates a pulse voltage of a predetermined duration, which flows to the recording-carrier electric motor 6, and moving the recording medium 7 to a discrete value, and the recording pin 4 returns to its original state.

On the forward xoD.y of the recording pin 4, the recording area selection block 9 produces pulses of the beginning and end of the recording zone, the temporary position of which, relative to the beginning of the movement of the squeezing pin 4, determines the location and size of the recording area of digital information on the recording medium 7. Start pulse the recording area from the output of block 9 of the recording area and the pulses of the oscillator 1 clock pulses are fed to the corresponding inputs of the first converter code - time interval 10, while at its output a pulse is generated, the duration otorrhea proportional to the code input to the converter 10 to data lines 22, and the start pulse coincides with the beginning of the recording area impu.1som. The impulse of the beginning of the recording zone and the impulses of the generator 1 also arrive at the corresponding inputs of the second transducer code - time interval 11. The pulse duration generated at the output of this transducer is proportional to the code received at its input from block 12 subtraction codes, which - is the calculation of the difference between the output kodbm encoder 13 of the recording area width and coh. bumped into block 12 subtracting codes over information bus 23. On the falling edge of the output pulse of the converter, trigger 14, returning to its initial state, arrives at its input with a pulse of the end of the recording zone from block 9 for allocating the recording zone. Thus, at the output of the trigger 14, a pulse is formed, the length of which is proportional to the size of the code received by the block 12 for reading the codes on the information buses 23, and the end of the pulse coincides with the pulse of the end of the recording zone. The pulse from the output of the first transducer code - time interval 10 and the pulse from the output of trigger 14 are sent to element 16 and OR 15. If these pulses do not overlap in time and their total duration does not equal the time interval between the pulses of the beginning and end of the recording zone (t. e. the sum of the codes on buses 22 and 23 is not equal to the end of the recording area width), the signal at the output of the AND 16 is absent, and from the output of the OR 15 both pulses go to the second input of the recording amplifier 8 and register on the recording media 7 with a writing pin 4 in the recording area in De two lines, the length of the line starting from the beginning of the recording zone is proportional to 9694 code value at the input of the first converter, the code is the time interval 10, and the length of the line ending at the end of the digital information recording zone is proportional to the code value at the input of the code reading unit 12 . If the pulse duration at the output of the converter code is the time interval 10 and the output of the trigger 14 is such that these pulses overlap in time, then the output of the OR 15 generates 1 pulse equal in duration to the time interval from the start pulse to the pulse of the end of the recording zone, and at the output of the element 16, a pulse is formed equal to the duration of the pulse overlap time. The impulse from the output of the impulse OR 15 goes to the second input of the recording amplifier 8 and displays the recording medium 7 with a recording pin 4 during its forward running of the line from the beginning to the end of the recording area of the digital information, and the impulse from the output of the 16 The element OR 18 on the brightness modulator 17 and further on to the first input of the recording amplifier 8 provides a large one. The length of the part from the beginning of the recording zone to the most distant point of the part of the line with increased brightness is proportional to the code value of the digital information at the input of the first converter, the code is the time interval 10, and the length of the line from the end of the recording area of digital information to the most distant point of the part of the line with increased brightness is proportional to the code value of the digital information at the input of block 12 of the code subtraction. In the case when, regardless of the code values coming from the information buses 22 and 23, their total value is equal to the code of the recording area width, the equivalence block 20 is triggered, the inputs of which receive a code from the output of the code sum block 19 on data buses 22 and 23 and the code from the output of the encoder width of the recording zone 13. The output signal of the equivalence block 20 is permissive for enabling the pulse shaper 21 from the output pulse of the first converter code - time interval 10. During the forward stroke of the writing element 4 n the output of the OR gate 15 in this case is formed by a pulse consisting of two x sleduyuvr each other without shetulsov interval kotormk total duration equal to the time interval from the start pulse to the end of the write pulse zoshl. On an impulse front from the output of the converter code - time interval 10, the pulse shaper 21 triggers, a short pulse from the output of which travels through the second element OR 18 and the luminance modulator 17 to the first input of the recording amplifier 8 and is recorded luminance located on the average luminance line recorded under the influence of a pulse from the output of the element OR 15. A high luminance label fixes the boundary between the corresponding information line on the tires 22 and the corresponding line Tire information 23.

Thus, the proposed device eliminates the ambiguity of reading the recorded information recorded in one zone in the form of two lines when the total length of the lines is equal to the width of the zone of their registration.
