FIG. 1 shows a diagram of the proposed device; in fig. 2 and 3 time diagrams of the device 1: in FIG. 4 is a diagram of a former.

The device contains a block 1 switching elements, switching elements (1-1) - (1-P), the element OR generator 3 pulses, driver 4 pulses, one-shot 5, the counter 6, the first trigger 7, the first element 8, registers 9 - 11. , the source key 12, the decoder 13, the second and third elements And 14 and 15, the second and third triggers 16 and 17, element 2 And-ШШ 18, the delay element 19, the inputs and outputs of the driver 4 pulses 20-27.

The device works as follows.

The device is reset to initial state by pressing key 12. By a signal from key 12, the counter 6 and the registrations 9-11 are reset, and the trigger 7 is set to the position that turns the driver 4 into the input mode (the input is connected (20 and 23 and outputs 25 and 26) .

When the operator presses one of the switching elements 1-t ... 1-n (or several at the same time when specifying each bit as a code), the output of the OR 2 element generates a signal allowing the operation of the driver 4. From the pulse generator 3, the signal is first generated at the output 25 shaper, and after some time at the output 26. The signal at the output 25 of the shaper 4 arrives at the summation of the input of the counter 6 and writes 1 into it. At the output of the counter 6, the unit code is generated and with the arrival of the signal from the one-shot 5 to the control input of the decoder 13 n and the output of the latter generates a signal arriving at the gate input of the register 9. Thus, the register of the register 9 records the code of the number from the first press and stores it.

The second pressing of one or several switching elements in block 1 will write the corresponding code in register 10, etc. The next time you press (the last digit you enter the Nforo number), the information is recorded in register 11, and the trigger 7 switches to the opposite state, switching the imaging unit 4 to the editing mode (inputs 23, 24 and 20 and outputs 27 and 26 are connected). At the same time, a signal is output from the output of the trigger 7 to the element 8 and to the output of the device, a signal to the end of dialing the number. The signal duration on the output of the one-shot 5 is much longer than the total response time of the counter 6, the decoder 13 and the trigger 7, therefore the output of the element Bj bupet Generate a signal with a duration equal to the difference of the signal duration at the output of the single-vibration 5 and the response time of the counter 6, the decoder 13 and trigger 7. The signal at the output of element 8 is a common gate signal, by which information from registers 9-11 is copied to the corresponding receivers. To enter a new number, you need to press key 12 and repeat everything as described above.

FIG. 2 shows a timing diagram of the main output signals from the outputs of the respective blocks in

input mode, and in FIG. 3 - in the number editing mode. The figure shows the transient time when one or another key T is pressed, the duration and period of the pulse from the generator 3 pulses Tj, T (to exclude false information created by interference when the switching elements are pressed, the condition T 7ir must be met) one-shot T-, Td (and the pulse from 1 G is shifted by for S10 the delay relative to the pulse c by i T-1), thus creating good conditions for the formation of one or another strobe signal from the outputs of the decoder 6 (first a counter, a clear code is set at the inputs of the decoder — the address of the corresponding register, and then a strobe signal is received at its input), fj is the total response time of counter 6, decoder 13 and trigger 7f5, the duration of the signal at the output of element 8 f, the number of keys pressed in the mode input 1 and m. In the editing mode, it is necessary to press the switching element, why the signal at the output 27 of the driver 4 is generated, the counter 6 will go to the state (rrv-l). Then press the corresponding element 1-1 ... 1-p, why a signal is formed at the output 26 of the driver 4, the one-shot 5 starts up, a signal is generated at its output that goes to the (t-1) output of the decoder .13 and writes the corresponding number in (t-1) register, etc. Editing 65 is bitwise, starting with the youngest. Working with the proposed device, the operator, keyboard input tn is a digit number, receives a signal about the end of the input, and connecting the display to the outputs of the registers, gets an opportunity to control the entered number, thereby entering any number becomes ordered, controlled, which results in account performance and efficiency of its work. In addition, the presence of the possibility of editing and controlling the size allows one to correct the input information that is bitwise, which is very important with a large number of bits of the input number. If the editing needs to be done in a non-fractional manner, and in any selected bit, then, by checking the outputs of counter 6 with the indication, the operator will see which bit of the number he is editing. All this increases reliability and speed. devices by simplifying the work of the operator.
