(Fig. 2). contains trigger 19, third element OR 20, delay element 21, first 22, second 23, third 24 and fourth 25 elements I. The fourth local control unit (Fig. 2) contains the fourth element OR 26, the key 27, the code converter 28 and the second shaper 29 signals. FIG. 1 and 2 are also denoted BxojQii 30 devices. The drive is built on universal four-register registers 31 with 32 output. The control unit contains a delay element 33, adders 34 modulo two, and 35 N 36 elements. The first local control block contains keys 37, code converters 38 / signal formers group 39 signals, AND 40 group, delay elements 41, and driver 42 signals. the second local control block contains a trigger 43 ft elements AND 44 and 45.

The device works as follows. .. :. . When a ready signal is present, output 16 from inputs 30 to inputs of accumulator 1 receives an information code with; an additional test bit, after which inputs 1 and element OR 2 are output from: a signal that writes information to drive 1, then it is produced .cont.- the role of the correct recording of information by block 3. If block 3 detects a malfunction of the received code, it will generate a fault signal at output 18. If the information must be entered again, accumulate: r1l 1. In the case of proper recording of information in drive 1, block 3 by polling signal 1 is bathed by the signal, the input to the driver 4 and the input of block 10, as a result of which the readiness signal is removed at output 16, and the output of the driver 4 produces a signal that asks for the inputs of elements And 5. In accordance with the info one The recording recorded in accumulator 1 from the outputs of the And 5 elements is fed to block 6, which solves information, for example, perforation, on a movable carrier, and also gives information about the result of information to the inputs of block 7. Block 7 compares the received signals with the corresponding bits of information read from accumulator 1 and, in the event that no bit of information is sent to the mobile carrier, generates a signal at output 13, which goes to block 8. Block 8 produces the signal that passes through the OR element interrogates the block 3 and, in the case of code corruption, read out from the accumulator 1, the forwarder 4 is restarted, the information is re-recorded on the mobile carrier. If, after re-punching, block 7 again outputs a signal to output 13 to block 8, the output of block 8 is a signal that is output through the element OR 11 to output 17, signaling a device failure. If block 7 determines that the information is plotted correctly, output 15 generates a signal that is fed to the input of block 12 and to the input of block 9. When applying the back track to the mobile media unit 12, you give a signal to the input of block 9, which sends to block 10 the signal that moves the storage medium to one line, after which block 10 outputs the 16 ready signal to receive the following information. If, after issuing a signal to exit 15, after a fixed period of time, from block 12 to block 9 there is no signal confirming the application of the sync track, block 9 sends a repeated signal to block 12 for applying synchro chatter. If, after issuing a second signal to perforate the sync track, after a fixed period of time, a signal about applying a sync track from block 12 to block 9 does not arrive, then block 9 generates a signal that, through the OR 11 element, arrives at output 17, signaling a device failure. If, when monitoring the application of information, block 7 determines the application of unnecessary information to the carrier, output 14 produces a signal that enters unit 10 by moving the information carrier one line without perforation of the sync track, then a signal appears the input of the OR 2 element, from the output of which block 3 is polled, and then the process of putting information on a new line of media is repeated. If, however, after re-applying information to a new media line, block 7 generates a signal at output 14, arriving at block 10, then block 10 generates a signal that, through the OR 11 element, enters output 17, signaling a device failure. Thus, on the line, on which the information is incorrectly applied, there is a perforation of the sync track, this allows for an additional correction of failures in the process of reading information. Since all information devices from a punched tape reader read information line by line from the sync track of the corresponding line, when reading information from punched tapes made on the proposed device, the lines incorrectly inserted by the informer will not automatically be read. The technical and economic advantage of the proposed device is higher reliability than the limelime device.
