The invention relates to computer technology and is intended to enter information into a computer.

The aim of the invention is to improve the speed of the device.

The drawing shows a diagram of the device.

The device contains a block 1 of switching elements, the first group of load elements 2, the load element 3, the second group of load elements 4, the first 5 and second 6 triggers, element I 7, the first 8 and second 9 groups of Schmitt tripers, the nerve 10 and the second 11 encoders, the first 12 and second 13 resistors, the first 14 and second 15 controlled sources of power, the first 16 and second 17 Schmitt triggers, the driver 18 pulses.

The input device operates in the following way.

In the initial state, the first 5 and second 6 triggers are in the zero state, element 7 is closed, it has the potential from the direct output of the first trigger 5, the first 8 and the second 9 groups of Schmitt triggers, the first 16 and second 17 Schmitt triggers, The first 14 and second 15 controlled power supplies are in the initial state. When a start signal is applied to the device input, the circuit elements do not change their state.

Pressing any button b; 1ka 1 will close the circuit: the first 14 power source, the load element 3, the first load element group 2, the vertical and horizontal buses of the switching elements block 1, the second 4 load element group, the second controlled power source 15 . At the same time, at the outputs of the selected Schmitt triggers from the first 8 and second 9 groups of Gimmitt triggers, the voltage levels will change, leading to their operation. At the outputs of the latter, in the vehicle, logic signals are received at the inputs of nepBoi o 10 and the second 11 ishfrators. In addition, voltages will also change at the inputs of the first 16 and second 17 Schmitt triggers, but when the button of the block 1 is pressed, only the first Schmitt trigger 16 is triggered. At its output, the signal that enters the input of the driver 18 impulses is activated. At the output of the latter, a pulse is formed and, on its leading edge, the information from the outputs of the encoders 10 and 11 will be overwritten, respectively, in registers 12 and 13, and on the falling edge of the same pulse, the first trigger 5 will be set to one. At the direct output, the level "1" will go to the first input of element 7. As the second input of level 7 also has level 1, the command "Device readiness." Will be formed at the output of element 7. State change

The first trigger 5 causes an "O" to appear on the inverse output, which affects the inputs of the first 14 and second 15 controlled power sources. At the outputs of the latter, changes in voltage levels occur, leading to the return of all triggered Schmitt triggers to the initial state.

The contents of the first 12 and second 13 registers correspond to the code of the closed switching element.

To receive a code with the first button pressed, after reading the generated code, the signal "HvcK" will be sent to the device input, which will set the first 5 and second 6 triggers to the zero state, which in turn will result in the installation of the first 14 and second 15 controlled power sources to their original condition.

If at the same time closed two n. If there are more switching elements, then the device works as described, except that the And 7 output of the element will be absent: “Ready – 1ness”. This is due to the fact that at the input of the second Schmitt trigger 17, there will be a sufficient change in the voltage level, which will trigger it. As a result, at its output, the Wits level is "1, setting the second trigger 6 to one state. At the inverse output of the trigger 6, the Wits level is “O and will close the element I 7, and at the right output, the Wits signal is“ Fault.

Thus, the device () for input of information allows to increase the speed, since there is no interrogation of horizontal and vertical pin blocks 1 of the KO.V1.M unit of the tactical elements and the code of the closed comm um of the automatic element of the forms and rusts immediately .
