(54) AUTOMATIC ELECTRONIC TELEGRAPH DEVICE

i

The invention relates to a technique for receiving and transmitting discrete information and can be used in electronic telegraph devices.

The answering machine of the electronic telegraph apparatus is known, comprising a series-connected distributor, a control unit and an encoder, the second inputs of which are connected to the inputs of the diaphragm unit l through the corresponding keys.

However, the known device does not provide arbitrary codes.

The purpose of the invention is to enable arbitrary codes to work.

The goal is achieved by the fact that the answering machine of the electronic telegraph apparatus containing the sequentially connected distributor, control unit and encoder.

the second inputs of which through the corresponding keys are connected to the outputs of the dialer; the input of which is connected to the second output of the distributor; the inputs of the corresponding keys. In addition, the control unit consists of n And elements, the outputs of which are respectively connected to the inputs of the first and second OR elements, while the output of the first OR element is connected to the first inputs of the trigger through the first pulse shaper, the outputs of which are respectively connected to the first inputs of the n elements And, and the output of the second element OR through a serially connected second pulse generator and the third element of the NL pin is very close to the second input of the trigger, while the second inputs and outputs of the N elements And the second input of the third lementa OR are respectively in-strokes and the outputs of the control unit. In this case, the encoder consists of n first And elements, whose outputs are connected respectively to the inputs nxm of memory cells, while the outputs of every m memory cells are combined and connected to the inputs n of the second And elements combined with the second inputs of the first And , while the other inputs of the nxm memory cells, the first AND elements, and the outputs h of the second AND elements are corresponding inputs and outputs of the encoder.

On fng. 1 shows the structural electrical circuit of the proposed device; in fig. 2 is a structural electrical encoder circuit.

The auto-T.leader of the electronic telegraph apparatus contains the distributor 1, the control unit 2, the contents of trigger 3, n elements AND 4, three elements OR 5, 6 and 7, and two formers 8 and 9, encoder 1.Q, key 11, dialer block, 12, driver, 13. code signs and output register 14. The encoder contains n first element 15 and nxm memory cells 16 and n second element I I7,

The device works as follows. .

When typing an auto answer, the shaper 13 is set to the necessary code and using block 12, a set of elements of the code pattern of the first character of the auto answer is produced. Upon completion of the character code dialing, an input signal is given, which is fed from the control output of block 12 to the control input of the distributor 1 and through the OR element 7 to the first input of the trigger 3. As a result, the n elements AND 4 are enabled and a signal appears on the control and the first outputs of the distributor 1. The latter, through the corresponding element I 4, together with the signal, developed under the influence of the signal from the control output of the distributor 1 at the output of the driver 13, records the code elements of the first character formed by the keys 11 in accordance with the combination typed in block 12 into the cell 16 p-amps of the encoder 10. At the end of the sinal from the former 9, the trigger 3 is reset, which is the read enable state jT.e. permitting the operation of elements I 4,

Then dialed on block 12 are the code elements of the second auto-answer character. At the end of the character code dialing, a second signal is supplied through the control output of the block 12, which triggers the trigger 3 to the recording enable state. This causes the signal to appear again on the control and the second outputs of the distributor 1. At the same time, as in the first case, The required cells of the encoder 10 indicated by the signal from the output of the corresponding element 4 and the signal from the output of the imaging unit 13 of the code are written into the code of the second character through the element 17. And again, at the end of the signal from the output of the corresponding element AND 4, the trigger 3 is reset.

Similarly, the codes of all characters (characters) of the text of the auto answer are typed. At the end of the set, the code conditioner IS remains in the set state in order to ensure that the write signals and read signals are identical, thus ensuring that the code of the readable code corresponds to the written one.

Claims (3)

When you start the answering machine from a telegraph machine (by a request from a line or by an operator), from the outputs of the distributor 1 starting 1T, the signals alternately arrive that alternately through the elements AND 4 together with the signals issued by the driver 13 of the code sign to the element 17 of the encoder 10 ) from the encoder 10 through its outputs codes of characters (symbols) of the text auto answer. Through the output register 14, the codes are fed to the transmitting distributor of the telegraph apparatus and to the second inputs of the keys 11, through which they confirm the state of the memory cells of the encoder storing the code of this sign. Suppose the first character is read. Then, when its code combination appears at the inputs of keys 11 by a signal from the output of the corresponding element AND 4 through the element OR 6, the driver 8 and the element OR 7, the trigger 3 is set through the corresponding element AND 4 (since the distributor 1 is still in the first position) with a signal from the output of the code generator 58 13 supplied through the AND 15 element of the encoder 10. The read character code through the keys 11 is fed to the encoder 10 to confirm the previous corresponding AND AND 4 state of the NIN memory cells 16. Upon termination of the signal at the output, trigger 3 by the signal through the element OR 5 and shaper 9 is set again in the read enable state. Similarly, confirmation of the source code is made in other cages of the encoder 10 memory. All this ensures high accuracy of the text of the auto answer text. In order to change the text of the auto answer, on the indicator 13, the code O is first set to block the operation of all elements 15 and 15 i.e., the erase mode is set. From the control output of unit 1 (without dialing a code on it), the distributor 1 is alternately started. As a result, under the influence of the signals from the output of the AND 4 elements and the form, On iruyuschego code at the outputs of all AND gates 15j memory cell 16 of the encoder 10 are set in a starting position r. e. answerback Wash old text is. Then on the imaging unit 13, the code is set by the operator, the indication of the desired code and the typing of the new auto-answer text begins. Thus, the change of the text of the auto answer, and the change of the code (code table) is performed without auxiliary equipment and operatively. The positive effect of the device is to increase the versatility of the device (i.e., without changing the structure, it can be applied to devices operating with a five-element, seven-element code, etc.) increasing the efficiency and reliability of changing the text of the auto-answer, increasing the reliability of the device by increasing. noise immunity of the shaping keys (since they have only two inputs each) and confirmation of the state of the encoder memory elements by signals from the outputs of the output register, which also increases the reliability auto answer text. 16.
