Description

the same number of n elementary control blocks, consisting of triggers And Ib, ..., Pn, circuits 12, 122, ..., 12p coincidence and elements 13 and 132, ..., 13 "delay. The shaper 5 of the code consists of a shift register 14, a twin-input collecting circuit 15, a matching circuit 16, a collecting-circuit 17, an interdiction circuit 18 and 19, a clock generator 20, and an output device 21. The call synchronization unit 7 consists of a collecting circuit 22 and a trigger 23 .

Sensor Morse code works as follows.

When one of the keys of the input block 1 is pressed, one of its outputs corresponding to the selected character enters the encoder 3. A signal is distributed to its ten outputs in accordance with (intermediate decimal digit code. From the outputs of the encoder 3, the code goes to the corresponding inputs the buffer accumulator 4 and is filled-in the memory line 10, the cells of which, in accordance with the code of the written word, go to the state "1. Simultaneously with each input character to the encoder 3, the control output is started from its control output control 8. At this, the trigger 111 triggers and issues a signal "I to a matching circuit 12i, at the other input of which there is already a signal" 1 from the subsequent trigger Ib. The matching circuit 12i triggers and delays information from the storage line lOi through the delay element 13i. the accumulator 4 and writing it to the subsequent ruler ruler 102. Simultaneously, the trigger 111 returns to the initial state, and the trigger 112, which thereby ensures the coincidence of the signals in the following circuit 122 coincides, is output from the initial state. the same information in advance following a storage line. Such advancement of information is carried out up to writing to the last memory line 10p with the corresponding operation of each elementary control unit 8. The delay elements 13 132, ..., 13 p are necessary in order for the information to be stored in the storage lines of the buffer accumulator 4 before the read signal from the elementary blocks of the control block 8 is received. Reading from the last Ytg memory line is performed by a signal from the trigger 23 of the call synchronization unit 7, which, in turn, receives a signal from the driver 6 intervals. The output speed (formation) of the code from the sensor in characters per minute is required, in accordance with the average speed of the operator, set by adjusting the frequency of the clock oscillator 20. At the same time, due to the buffer memory, some deviations of the input speed from the output speed are possible, caused by both uneven code and uneven operator's work on the keyboard. The call synchronization unit 7 eliminates the coincidence of the pulses from the last storage line 10 of the buffer accumulator 4 and the read pulse from the clock generator 20 fed to the shift register 14, since the coincidence of these pulses would lead to their mutual compensation and, therefore, loss of the shift entered into the shift register 14 code word.

Thus, the promotion of information from one storage line of the buffer storage device 4 to another occurs as it is read from the last storage line 10 "by the signal from the call synchronization unit 7. In case of a sudden increase in the input speed, i.e., when all the storage lines of the buffer accumulator 4 are filled, the lock 2 triggers, controlled by the integrator 9, when all the triggers 11, Ib, .., Pi of the control unit 8 are out of the initial state. When the sensor is operating, the clock generator 20, one output, writes "1 to the inhibit circuits 18, 19 and shaper 6 intervals, advances the information recorded in it in the shift register 14 and causes the trigger 23 through the collecting circuit 22 to its initial state. From another clock output; the second generator 20 — reads the recorded “1 from the prohibition circuits 18 and 19”. When read from the inhibitor circuit 18, the output device 21 is de-energized. In the event of a coincidence of signals at the inputs of the coincidence circuit 16, the latter issues a signal that prevents the recording of "1 into the prohibition circuit 18, and the output device 21 is not brought to a currentless state, thus forming a dash. When reading from the prohibition circuit 19, the signal from its output through the interval imaging unit 6 outputs the flip-flop 23 from the initial state, which thereby gives permission to write information to the shift register 14 from the last memory line 10 and buffer storage 4 and simultaneously write information to the register 14 the shift is brought to the initial state via the collecting circuit 22. The signal from the output of the interdiction circuit 19 arrives at the shaper of 6 intervals only in the absence of information in the shift register 14, i.e. in the absence of the interdiction signal to the interdiction circuit 19 from the collecting circuit 17.
