Joining is related to the field of avivivlruKH and computing technology, and it can be used in devices for input and display of information,

TiBBecTHbi display devices in which the magnitude of the light of a bar

measures the measured value and ensures its continuous visual inspection 1. I

The closest technical solution to this invention is a device. containing the first counter, connected to the k decoder, the outputs of which are connected to the control electrodes of the counting indicator tube, the second counter, connected by i & with a group of elements And, associated with the input busbars, counters and ({elucidating gel of damping pulses connected to} the zero electrode of the counting tube, and the pulse generator 2.

However, such a device provides an indication of numbers in the form of a continuous light - tsegos .. etolbika, and in a number of cases it is advisable to allocate separate areas for comfort;

The purpose of the invention is to enclose the quality of the display by means of the velocity modulation of various sections of the counting tube.

This goal is achieved by the fact that the prepositional device contains two triggers and element I. The counting input of the first trigger is connected to the output of the second counter, the usdr; input - to the output of the group of elements And, and the output - to the installation input; iy of the second trigger, the counting input which: o is connected to the pulse generator connected to one of the inputs of the element I. The second stroke of the trigger is connected to the other stroke of the element And, the output which is connected to the inputs of the counters. The drawing shows a block diagram of the proposed device.

I It contains counters: and 2, decipher top 3, shaper 4 extinguishing pulses, counting indicator tube 5, group of elements I 6, pulse generator 7, Hera triggers 8 and 9, and element I, 10. The device works as follows. The input of the counter 1 receives pulses from the pulse generator 7 through the element IO, At the outputs of the decoder 3 connected to the control electrodes of the counting tube 5, a sequence of signals occurs, which causes movement of the discharge through the anodes of the tube from bottom to top. The pulses from the pulse generator 7 also go through the element E10 to the input of counter 2, As soon as the code on the course of this counter coincides with the code on the input buses, a signal appears at the outputs of elements And 6, which resets the counters 1 and 2 and launches 4 pulse shaper. The latter produces a reset pulse, which arrives at the zero electrode of the counting-tube 5, converting it to the zero position, which is signaled by a dot against the zero anode. The output of the counter 2 is connected to the counting input of the trigger 8, therefore, every tenth pulse arriving at the input of the counter 2 transfers the trigger 8 to the opposite state. The latter controls the operation of the prohibition circuit of every second pulse coming from the pulse generator 7 to counters 1 and 2, consisting of trigger 9 and element 10, At the output of trigger 8 there is a zero potential prohibiting the operation of trigger 9 in counting mode. The output potential from trigger 9 permits the passage of pulses through element IO to the inputs of counters 1 and 2. The appearance of a single potential at the output of trigger 8 removes the restriction from trigger 9, and the latter switches to the same mode of operation at which the inputs of counters 1 and 2 only every second impulse from the pulse generator 7 passes. This leads to a doubling of the generator period. In so doing, the corresponding luminous elements of the counting-indicator tube 5 are taken as more prominent. Thus, areas of more or less bright luminous groups of ten elements each, with the exception of the uppermost one, which can have any number of elements from one to ten, are formed on the illuminated column. The invention is a display device comprising a first counter connected to a decoder, the outputs of which are connected to control electrodes of a counting tube, a second counter connected to a group of elements And connected to input buses, counters and a driver of damping pulses connected to the zero electrode of the counting tube, and a pulse generator, characterized in that, for the purpose of quality improvement and dictation, it contains two triggers and an AND element, with the counting input of the first Hera connected to the output of the second counter, the setup input to the output of the group of elements I, and the output to the installation input of the second trigger, the counting input of which is connected to a pulse generator connected to one of the inputs of the element I; the output of the second trigger is connected to another input element And, the output of which is connected to the inputs of the counters.
