The invention relates to the field of No. 1 computing technology and can be used in output devices. Computers, in the Information System of Information Systems in India, in automatics, rostroeshi and automatizirovannyh control systems,;, /,. ..- -: ..:

A device for displaying information on the screen of a cathode-ray tube (ZAG) is known. It contains the receiving register, the distributor of micro-tacts, the elements AND, OR, the trigger, the shape of the circuit and the current (current),

The disadvantages of this device is rather complex hardware, and the implementation of low reliability of the device. . , -. -. , -:; .. -.-; ; . The closest technical solution to the camera is a device for displaying information that contains the last register on the CRT screen, connected to the first inputs of the elements And the perboy and the second

Groups, the second inputs of the elements of the first group are connected to a single output of the trigger, the third inputs are from the second, third, fourth and fifth outputs of the distributor of micro-tacts, ry inputs of cements of the second group are connected to the first, trigger input, the third inputs are “- the second, third and quarter outputs of the micro-tact distributor, and the outputs of the first and second groups of the elements are connected to the input of the OR element, whose output is connected to the CRT module, the trigger, the counting input of which is connected to the first output of the microactor acts, fo Offsetting voltage regulator, connected to the Y coordinate coordinate system, delay, oo and dknnenny with the coordinate coordinate deviation system.

The disadvantage of this device is that in order to open the function (current, voltage) with respect to Y, it must have a deviation amplitude, ensure- This is the deviation of the electron beam along the length of two segments (the slice of the polygram), which causes a high demand for otkoreneniz systems. The formation of large volumes of information (the amplitude amplitudes of the deflecting factors (currents, irradiations) reach a great deal of magnitudes and the otg slon & s systems operate in a highly thermally controlled mode..;; - -.;. -; -; ;; .., ..

The device works cneiSyioiaHM: pattern: Digit to be With & nyu on CRT, receives the receiving unit 1 in a binary semi-bit code, while in those bits of the code that correspond to The frames of the first component of this digit are recorded, and in the code bits corresponding to unused segments of O. 6 7i micro-tact distributor 10 Bybrashaet pulses, at the outputs, 10 (j one relative to the other and ONE). These impulses come in the inputs of the elements I 2-8, 12-15 and rigger 11, when comparing the code of the displayed digit with the impedance of the PM 10 and the potentials of the trigger 11 on the input of the elements. And 2-8 stand out, corresponding to the segments of this figure, This sequence,% of the pulses highlighting the lepea element OR 9 enters the modal mountains 24 SLT. . Under the action of the second and fourth pulses of PM 10, the output of the driver 16 is formed by a sigl (current, voltage), which is fed to Systemu by deviating the coordinates of Y 23, and through the delay element 2 O to the system of deviating the coordinates of K 22. The first pulse from the output of 10d PM 10 arrives at the counting input of the trigger 11 and sets it in one state, V. the power of this state is formed or the bottom (the trigger is in the state O), the upper one (the trigger is in the compository I) square. Through n p, tsstov from the first exit 10 of the PM 10, the pulse returns again, which translates the trigger C into a different state. As a result, half of the half-gram is formed. The process of forming half of a polygram is performed by controlling elements 12–15, 18, and 17. When trigger 11 is in a single STATE, this output will affect the inputs of Elements 2–5, 12, 13, 17, 18, when it is free at E1H5M ffmming the upper half of the polygram. When the trtter 11 is in the zero state, the potentials from the zero output act on the elements of 8, 14, 15, B atoms of the trigger state 11 on one of the inputs of the circuit 18. There is no signal from the circuit 17 and the signal off. This ensures the formation of the lower half, polygrams Thus, the device makes the electron beam move symmetrically to both sides of the 6T center of the polygram, which causes a decrease in the amplitude of the function of the deviated along the Y coordinate. In this case, the thermal condition of the deviating systems is improved and the reliability is increased.
