Isofetenenne refers to automated systems of abrasion and computer engineering.

According to the main auth. J 423116 knows a device for entering information from single carriers of the type of punch and magnetic cards, including permanent gaps with coded information in them, which allows all of this device to be used at automatic checkpoints.

This device contains a decoder triggers, schemes of SS zpa / n (AND schemes), assembly scheme (OR scheme), 1-register register, external readout module, including a reading unit; information bits and a readout node for additional coding patterns, the decoder outputs are connected to single inputs of serially connected triggers and to coincidence circuits (circuits I), other inputs which are connected to the corresponding inputs of triggers, and outputs of matching circuits through an assembly circuit and (I scheme) are connected with fl fl.

A disadvantage of the known device is the complexity of external readout having information and code channels, including the readout section of the nfssh madionnk bits and the readout section of additional code combinations,.

The goal is to simplify devices -

f by combining information and code channels.

To achieve the goal, ycTitoucfBO for entering information is entered

s f (the globalizer, the output of which is connected to the decoder, and successively connected to the counting trigger, the setup input of which is connected to the initial bus, the counting input is connected to the readout device, and the output is connected to the input of the imager, AND elements, the other inputs of which are connected to the block with reading , and an intermediate register. 38 Korqaoro outputs are connected to a Yeshkfrator. The drawing shows the functional diagram of the proposed device. The device contains a decoder 1, triggers 2, elements AND 3, element OR 4, receiving register 5, a readout unit 6, an intermediate register 7, a group of code elements AND 8, a trigger 9, a fipper 10. The device has an initial setup wire 11 for providing an external signal for resetting all triggers to the initial state. The input of the shaper 10 is connected to the output of the trigger 9, and the output is connected to the gate input of the decoder 1 "The other inputs of the decoder 1 are connected to the outputs of the intermediate register 7, whose inputs are connected to the outputs of the code element group AND 8" The first inputs of the AND elements 8 are connected to the outputs of block 6 of the link, and the input S are connected to the output of the trigger 9, the counting input of which is connected to the output of the readout unit 6. The readout node, in contrast to the known device, is used both for reading information bits and for reading additional code combinations. The device works as follows. In the initial state, from the outputs of triggers 2 and 9, a signal is received, corresponding to a logical unit, to the inputs of the elements 3 and 8. The reading unit 6 sequentially reads the code combinations and information bits from the carrier. In the process of bit reading information from the media from the read node, the elements AND 8 receive a combination of code that determines the sequence number of the subsequent information bit. This code combination through the elements 8 enters the intermediate register stored by this register and enters the inputs of the decoder 1. The same code combination enters the readout node 6 to the receiving register 5, but the reception (registration) of this register does not occur due to the absence of a signal at the input of register 5 (at the output of the circuit OR 4), then from the node 6 read to. the information bit code read from the carrier and, simultaneously, a pulse to the counting input of the trigger 9 steps. with the input of the transmitter 10, a voltage drop is generated that triggers the driver 10. An impulse from the output of the driver 10 is fed to the gate input of the decoder 1, the first signal of the desh (| ratora 1 corresponds to the code combination registered by intermediate register 7, This pulse passes through the first element 3 and the element OR 4 to the enable input of the receiving register 5j, as a result of which the information bit code is registered by the receiving register. With the falling edge of the first output of the decoder 1, the first trigger 2 overturns a single loss from the input of the first element And 3, Due to this, it is prohibited to re-register the receiving information register of the same information (accompanied by the same additional code combination). After that, from the outputs of the readout block 6, it enters the input of the AND 8 elements of the (new) code combination. At the same time, a pulse arrives at the counting input of the trigger 9, on the leading edge of which the trigger 9 tilts again, opening the elements AND 8, therefore the code combination - from the output of the read 6 passes through the elements AND 8 and is stored by the intermediate register 7. Then the code goes from the 6 read of the next information bit, which is recorded by the receiver 5 by the register 5 according to the resolution signal received from the second output of the decoder 1 and passed through the second element I 3 and the element OR 4, the falling edge of this pulse is rokidyvaets second flip-flop 2, removing .edinichny potential from the input of the AND vtsrogo 3. Thus are recorded sequentially receiving register all codes information bits received from the reading unit. The pulses arriving at the counting input Tplirrepa 9 simultaneously with the arrival of the additional code combinations read from the BLUX 6 read the trigger 9 into a state allowing the code combination to pass to the intermediate register. Shaper 1O while not

runs. The pulses arriving at the counting input of the trigger 9 simultaneously with the arrival of the d information block of the 6 codes of information bits, transfer the trigger 9 into the state prohibiting the passage of the codes of information bits to the intermediate register 7, and the differential at its output starts f: 1O , the impulse from the output cohort ensures registration of the incoming code of the next information bit by the receiving register 5.

The invention allows to obtain knowledge. a distinct exhomical effect due to the simplification of the external unit This reduction is especially significant with respect to data entry devices in automatic systems that use hidden-information carriers that are protected from deliberate distortion of information.
