The invention relates to the field of sociological measurements and can be used as a voting device (usually secret) in determining the opinion of a group of people and in a number of other cases,

The aim of the invention is to simplify the device.

The drawing shows a block diagram of a voting device.

The device contains a pulse generator 1, trigger 2, element I 3, counter 4, block 5 of indication of N triggers 6 (N is the maximum number of voting participants), N keys 7, switch 8, N of the first elements AND 9 and N of the second elements 10 Elements 6, 7, 9, and 10 are part of the N accounting channels.

The device works as follows.

In the initial state, the triggers 6 and the trigger 2 are set to the zero state, in the counter 4 the code of the last measurement number is stored. The device returns to its original state after each vote. The common terminal of the switch 8 is set to Off.

The start of voting corresponds to setting switch 8 to position 1. The opinion of each voter determines the state of key 7 of the corresponding accounting channel 11. When the key 7 is pressed, the pulses coming from the output of the generator 1 through the switched on key 7 are fed to the single input of the corresponding trigger 6, setting it to state 1. In addition, these pulses set the counter 4 to the state 99, .. 9. More precisely, the first of the pulses sets the triggers 6 and the counter 4 to the indicated states, the remaining pulses

In principle, they are superfluous, but they do not change the physics of the processes taking place.

To count the votes (opinions of voters) that pressed the corresponding key 7, switch 8 is set to position 2.

The first pulse from the generator 1, with its falling edge, will translate trigger 2 into a single state. The second pulse will pass through the element I 3 to the counting input of the binary-decimal counter 4, set it to the state O and to the second inputs (on 4eJ3Tjeare - upper) elements I 9 10,

At the same time, if trigger 6 is set to state O, the pulse will go to the second inputs of the following (9) elements located below (in the drawing). In case trigger 6 is set to state 1, the pulse passes through AND 9 the corresponding channel 11 of the metering device and sets the trigger 6 of this channel to the state O.

The input to the input of the counter 4 will be carried out until all the triggers 6 are set to state O. When all the triggers 6 are set to state O, the pulse from generator 1 passes through the open elements AND 9 and goes to zero trigger 2 input, closing the OZ element.

Thus, if K triggers were set to state 1, then K + 1 pulses will go to the input of the counter. Taking into account that before the start of the counting, the counter was set to the state 99 ... 9, the counter K will record the number K in the binary-decimal code, which will be fixed by the display unit 5.
