The invention is lacking in automation and computing technology and can be used in devices designed to input / output information from the screen of an electron-beam tube into an electronic computing machine (computer).

The purpose of the invention is to increase the reliability of the device by eliminating operator errors.

Fig. 1 is a block diagram of a device for input and output information; in fig. 2 and 3 are temporary arpaMMbi device functions.

The device for input and output of information contains a generator of 1 clock pulses, an E1th counter 2, a fifth counter 3, a fifth trigger 4, a second trigger 5, a second comparison element 6, a first comparison element 7, a first element 8 AND, a fourth element 9 AND fourth counter 10, first counter 11, third element 12 And, sixth trigger 13, second decoder 14, third element 15 OR, first decoder 16, first element 17 OR, sixth element 18 And, second counter 19., third counter, 20, second element 21 OR, third decoder 22, fourth decoder 23, video monitor the third one (24), the third trigger 25, the eighth trigger 26, the RAM block 27, the second element 28 And the first trigger 29, the fourth trigger 30, the seventh trigger 31, the fifth element 32 And, 33-78 of the device.

Generator 1 is a sequentially connected pulse generator, pulse counter and encoder of a series of clock pulses. The timing diagrams of a series of clock pulses are shown in FIG. 2

Counters can be built using K155IE7 type microcircuits.

Triggers can be built using chips, such as type K15TM2.

Elements 6 and 7 of the comparison are built on elements of one-by-one comparison, for example, type K155LP5, the inverted outputs of which are combined by AND

The RAM block 27 can be constructed using K-type 565RU1 chips. In this case, the RAM 27 is a serially connected RAM drive itself to the RAM code register, the output of which is the output of the RAM 27.

32

Decoders 14, 16, 22, 23 are gated code decoders.

Counters 2 and 3 contain the address of the location of the label on the VKU 24 screen. Counter 2 contains the code of the address of the familiarity inside the row, and counter 3 contains the code of the line number in which the label is located. Counters 2 and 3 are co6d serially connected elements OR (for example, on microcircuits of type K155LE1 or K155LL1) and counters (for example, on microcircuits of type 1C155IE7). At the inputs of the elements OR. External (i.e. arrival from the keyboard via bus 69) and internal meter control signals are supplied: +1 to counter 3, about 0 counter 3 and about 0 counter 2, and the OR element outputs are connected to the corresponding counter inputs.

Counter 10 contains the address of acquaintance inside the current line when displaying information on the VKU 24 screen. Bus 44 sends the input signal to counter 10 input, incrementing the 1st contents of counter 10. The counter is reset by a signal on terminal 45.

Counter 11 contains the current line number. Bus 76 is connected to input +1 of counter 11. Counter t1 is reset by a signal on bus 46.

 The counter 19 sets the delay in the input of information on the screen of the ICS 24 for the time of the return path of the beam on the line. A bus 53 is connected to the input +1 of counter 19. Counter 19 is reset by a signal on bus 54.

The counter 20 sets the delay in outputting information to the screen of the ICS 24 for the time of ray retraction across the frame, and during the forward path of the beam over the frame it counts the number of output television lines. A bus 54 is connected to input +1 of counter 20. Counter 20 is reset by a signal on bus 55.

Trigger 4 stores, an indication that a tag can be located in the current line. A trigger is set by 4 signal on link 75 when the decoder 23 interprets the code for the image of the tag of the television line. The trigger 4 is reset by link 76, when the decoder 23 will interpret the code of the last television line in the character string.

Trigger 5 blocks the passage of pulses to the input and counter 10

during the return path of the beam on the line. The trigger 5 is set by a signal on the connection 33 at the moment of the beginning of the forward path of the beam, when the trigger 5 is installed, the inputs +1 of the counter 10 begin to receive pulses. The trigger is cleared by a signal on the link 34, when the decoder 14 interprets the code of the end of the television line of symbols, or a horizontal sync pulse is received on the link 54.

The trigger 13 switches off the indication that the label is dropped out of the image displayed on the screen. The trigger 13 is set to one by the j-j parallel code at the generator input.

the front (transition from low to high state) of the signal at 48, and is reset to zero by the signal at 49, Thus, if by the time the HR sync arrives, 20 pulses through 46 of connection, trigger 13 remains set, This means that the image of the label on the screen of the VKU 24 is not displayed.

Trigger 31 stores a sign that 25, after transferring the mark to the beginning of the next symbol line, the mark on the VKU 24 screen did not appear. At the NF input of the trigger 31, a signal is fed via the lv characters into the pulse code sequence of modulating pulses, illuminating the spread on the screen of the electron-beam tube in accordance with the raster television standard.

The device operates as follows.

Each time a frame clock arrives, counters 1 1 and 20 are reset, as well as trigger 26, Counter 20 starts counting the retraction time across the frame. As soon as the decoder 23 interprets the end code

52, the information on the D input enters the reverse of the frame, it signals a signal to the trigger 31 on the leading edge of the signal on the communication 48, which is fed to the C input of this trigger. The trigger is reset asynchronously by the signal on the link 49, Link 78 is the direct output of trigger 31, and link 77 is the inverse.

The trigger 25 stores the sign of a forward move along the line. The trigger 25 is set by a signal on the link 60, when g decoder 22 interprets the code of the end of the reverse stroke on the line. Flip-flop 25 is reset, like flip-flop 5 by signal at link 34, Bus 62 is the direct output of flip-flop 25, and link 45 is the inverse of the flip-flop.

A trigger 29 is used to scale the characters along the X axis within a string. Trigger 29 is used as a frequency divider (inverse output 50 of trigger 29 is connected to the D input of trigger 29, and C input is used as a counting input). To the synchronization input of trigger 29 (this is C input)

via communication 51, resets counter 20 and sets trigger 30. Once trigger 26 has been installed, pulses are applied to input +1 of counter 1 1 and reset to trigger 4 (see link 76).

When the line sync pulse arrives over communication 54, counter 19 and trigger 25 are reset, Counter 19 begins counting the return stroke time on the line. As soon as the decoder 22 decrypts the end-of-turn code for the line, it sets trigger 25 by means of communication 60, After trigger 25 is set, the reset signal is removed from counter 10 through communication 45

If at the time of installation of the trigger 25, the trigger 26 is also set (the mode of the forward path of the beam), then the leading edge of the signal over the link 33 is set to the trigger 5, the signal along the same link (the sign of the high signal on the link) allows the output labels on the screen VKU 24

connection 50, resetting trigger 29, implement 55 (cm, element 9 AND and connection 49),

is a signal on connection 67 (connected to the R input of trigger 29).

The trigger 30 contains a sign of an increased scale along the axis Y

After the installation of trigger 5 via communication 38, it permits the passage of count pulses to counter 10, triggers 25 and 26 are set

lines. The trigger 30 is set by a signal on the link 68, and reset by the signal on the link 76.

The device also includes nodes for editing and outputting the contents of block 27 to the screen of the internal control device 24, however, in FIG. 1 they are not listed as being of no significance for the proposed technical solution. An information code (or a tag on link A9), which is input to the input of the VCU 24, enters the input of the generator of symbolovols (contained in the VCU 24), which converts

characters in a pulse code sequence of modulated pulses, illuminating the raster deployed on the screen of an electron-beam tube in accordance with the television standard.

The device operates as follows.

Each time a frame clock arrives, counters 1 1 and 20 are reset, as well as trigger 26, Counter 20 starts counting the retraction time across the frame. As soon as the decoder 23 interprets the end code

 reverse frame, it is a signal om

via communication 51, resets counter 20 and sets trigger 30. Once trigger 26 has been installed, pulses are applied to input +1 of counter 1 1 and reset to trigger 4 (see link 76).

When the line sync pulse arrives over communication 54, counter 19 and trigger 25 are reset, Counter 19 begins counting the return stroke time on the line. As soon as the decoder 22 decrypts the end-of-turn code for the line, it sets trigger 25 by means of communication 60, After trigger 25 is set, the reset signal is removed from counter 10 through communication 45

If at the time of installation of the trigger 25, the trigger 26 is also set (the mode of the forward path of the beam), then the leading edge of the signal over the link 33 is set to the trigger 5, the signal along the same link (the sign of the high signal on the link) allows the output labels on the screen VKU 24

After the installation of the trigger 5, the signal over communication 38 permits the passage of the counting pulses to the counter 10, While the triggers 25 are set and 26

5-13

in counters 10 and 11, information is displayed on the ICS screen 24. Triggers 25 and 26 are reset in two cases. The first case is when the counter 10 counts to the last character in the line displayed on the screen (the trigger 25 is reset by a signal on communication 64), and when the counter 11 reaches the last line displayed on the screen (the trigger 65 is reset by the signal 65 ). The second case is the arrival of the horizontal sync pulse (the trigger 25 is reset) and the arrival of the frame sync pulse (the trigger 26 is reset). The second case occurs when scaling, when the counting of counters 10 or 11 slows down and the horizontal (frame) sync pulse arrives before the counters have time to count to the last character (token) in the line or to the last line.

Scale indications are stored in block 27. When scaling the x-axis of the X axis, it is possible to control the scale of each character in the string. For this, the sign of a scale along the X axis is written to the address of each character of the line. This sign reads on link 67. If the sign is set to zero (the scale increases), it removes the reset signal from trigger 29 and this trigger starts counting pulses 50, In this case, the signal from the output of the trigger 29 through the link 74 reduces the frequency of the pulses on the link 44 by half.

When scaling along the Y axis, the scale attribute is written only to the address of the first line of the line and the whole line is displayed. The symptom is read to the link 68 and sets the trigger 30, the signal from the trigger output. Gera 30, through communication 66, reduces by a factor of two the frequency of the pulses, postut: them, at communication 47,

When scaling part of the information ceases to be displayed on the VKU 24 screen, the MSSET disappears from the field of view and the mark. In this case, editing the information on the screen of the ICS 24 becomes impossible.

The address of the mark on the screen is determined by the contents of the counters 2 and 3. The output of the mark on the screen of the ICS 24 is determined by the equality of the codes in the counters 2, 3 and 10, 11, the codes on the elements 6 and 7 are compared. When is equal to 36

In code counters 2 and 3, counters 10 and 11, and with trigger 4 installed, the mark image is displayed at the time of the forward path of the beam. on the screen of the internal control unit 24 (cm, connection 49),

When scaling is applied, the label can be exceeded beyond the limits of the image reproduced on the screen of the ICS 24. Moreover, going beyond the limits of the reproduced image is possible both when moving the label horizontally (i.e., beyond the vertical border) and when moving the label vertically (i.e., going beyond the horizontal border of the reproduced image),

If there is no mark in some frame of information on the VKU 24 screen (time between two pulses on the bus 46), then before the beginning of the next frame the output of element 18 I forms a signal that sets the mark at the beginning of the next character string. If in the next frame on the BIO 24 screen the label did not appear (sign of overshoot of the reproduced image), then the output of element 32 And a signal is formed which sets the label at the beginning of the screen (counter 3 is set to O)

The time diagrams of the device operation are shown in FIG. 3, where a is the diagrams of the device operation in the absence of a mark outside the image; b - when going beyond the vertical border of the image; c - when going beyond the horizontal border of the image.

Thus, in the process of filling the screen, the natural order of movement of the mark is preserved and the operator may not even suspect that the mark has gone beyond the boundaries of the reproduced image.

The use of new elements — the first address counter, the second address counter, the first comparison element, the second comparison element, the second element And, the first installation trigger, the second installation trigger, the fourth And element, the sixth And element, the forward stroke trigger on the frame favorably input and output of information from the prototype, since the label retains the common order of movement even when scaling is applied, and the operator not only does not have to spend time returning the label to that screen area. ana in which he works, but he may not even suspect that the mark; 1 has gone beyond the border of the reproduced image. In addition, the programmer's work is facilitated, since in a number of cases, when writing the program, we do not follow the length of the line when scaling is applied, or the corruption of the preceding information is avoided when the label goes beyond the vertical border of the reproduced image.
