Description

I

The invention relates to computing and can be used for outputting and editing information on the screen of a 1-tube (CRT).

Izvesnye devices for displaying graphical information containing a projection CRT, a tape mechanism, a photocell: CT, a multiplier, a selector, electronic amplifiers, horizontal and vertical scan generators, a synchronizer,: memory, CRT, input register, coordinate transducer, CRT, indicator CRT photo sensor.

A disadvantage of such devices is the impossibility of implementing program or manual image fragments.

The proposed device differs from the known ones in that one pair of deflecting plastids of the memory CRT is connected through the first switch from the output of the coordinate amplifiers to the outputs of the direct current generators: to and frames, to the output of the frame generator. the indicator CRT system, and the row generator output is connected to the deflection systems of the scanning and indicator CRT. The bluetooth input is stored behind the torus and is connected to the input of the video output amplifier: ala and to the output of the selector, the additional one of which is connected to the output of the search code amplifier. The output of the pulse amplifier is connected via a second switch to the CRT memory modulator and to the output of the video signal amplifier.

The drawing presents the block diagram of the described device.

The device contains a CRT scanner / with deflecting system 2, lens 3, diaphragm 4, microfilm 5, condenser lenses 6, photoelectric multiplier 7, video amplifier 8, selector 9, synchronizer 10, row generator 1J, frame generator 12,. input registrar 13, coordinate transducers M and 15, transducer / 6 search code, coordinate amplifiers 17 and} 8, amplifier 19 of the search code that records CRT 20 with deflection plates 21-24, modulator 25, target 26 and the next electrode 27, image signal amplifier 28, hydrochloric CRT 29 with the deflection yoke 30 and siste.moy modulator 3 / photosensor 32, pulse amplifier 33, switches 34 and 35, tape transport mechanism Zb.

The device works as follows.

The digital code carrying information about the search code of the image element is fed through the input register 13 to the search converter 16 of the search KOiaa, where it is converted into a continuous search control signal of the input images. The analog signal from the output of the search code converter Ifi after amplification by the amplifier 19 of the search code enters aia one of the inputs of the selector 9. The pulses generated in the other input of the selector are produced (the result of the L-look pattern read by the NNoso is recorded on the microfilm 5. The microfilm stores image of the element, aiainp TMep of the drawing, as well as its search code.

Reading of the graphic information is carried out by the method of, "traveling beam" using a scanning CRT 1 and a photomultiplier 7. The euran of the raft. strip of readable microfilm frame. Depending on the transparency of the sections of the filter film, the brightness of the luminous flux that enters the photomultiplier through condenser lyses is changed. 6. The modular power of the light tray is converted by the photomultiplier 7 to the electric pulses from the photomultiplier output. the search cad pulses.-iB selector 9 enters, and the image signal goes to video signal amplifier 8, which is in the ziert state. In case of a match on the duration of the i.pulses of the microfilm's search code with the search KS1DOM, fixed in the input register 13, the output of the selector is wired and an impulse that triggers: geerator 12. Frames and unlocking amplification of the video signal 8. Ta; The original image of the drawing element is read.

The stationary movement of the slider during the reading of the ix-one frame is provided by the L-36 36 interlacing. The scattering of the CRT beam / along the line is performed by the generator // of the lines using the decoupling system 2.

The signal from the output of video-amplifier 8 goes through switch 35 to modulator 25. Memorizing CRT 20. In recording mode, an electrically-induced beam of CRT, emitted by the input video signal, forms on the surface € s m.shin: and 26 notelts.ial “ 1st relief. In case of coincidence, and the return of the | AE (Switch 35 .n-ahyudits. In neutral lozheiii), this loti-relief is reconstructed in the video signals: which are removed from the signal of the type 27 and the “la us” signal 28 .Spial "in .from obrazaii-. From the output of this amplifier, video broadcasts are fed to modulator 31 of an indicator CRT 29. At the same time, a flow of the readable element is reproduced on the offset system 5 (7, an CRT screen is created.

Synchronous OBLO: natural operation (1st ray of the hall-tied. And indicator CRT is set by the row generator // And 12 frames for the geoerator, and also the synchronizer 10:

The automatic erasing or finishing of elements from the image is done by programmatically controlling the beam with a ZNOMINA CRT (switch 35 is in the neutral position, and switch 34 is extremely right). The signals of the DF01 of the computational machine, “Esui1, and Informat.c”, but about coordinate movements of the beam of the memory CRT, through the input register 13 are sent to the coordinate) 1st converters 14 and 15 and are converted by them into a continuous signal. beam movement

but target 26 zapom.11 ayun; e 1 CRT. These signals are amplified by the coordinate amplifiers 1/7 and 18 and are fed to horizontal plates 21, 22 and horizontal plates 23 and 24 of the vertical deflection of the beam of the CRT memory.

The selection or deletion of fragments of the drawing and the memory tube memory is missed by the change in its operation mode.

In the recording mode, the modulator 25 of the memory CRT 20 is iodine with a high negative potential relative to the target, and in the test mode, simultaneously with a decrease in the negative potential of the modulator, the current of the electron beam increases. Manual drawing or erasing of image fragments is carried out using a photo sensor 32.

With a SYNH-RONNO .-. M, the beam opens a memory 20 and an indicator 29 CRT in a wind, when the light spot of the indicator CRT falls into the photo-field of the photosensor, and amplified signals appear in its output (Pulse amplifier 33 - and the modulator of the CRT memory is supplied to the modulator 25. Depending on the operating mode of the individual CRT, it is necessary to take care of or erase the elements of the image on its target, to which it orders the photosensor during the movement of the CRT.
