During operation of the control unit 9, the generator of the synchronization pulses 30 produces pulses that synchronize the operation of the entire device. From its output, the pulses arrive at the inputs of the modulation unit 7 (connection 61) and the counter 31.

Pulses carry from the second output of the counter 31 are fed to the first input of the counter-32. Pulses carry from the second output of the counter 33 is fed to the first input of the counter 34.

33 and 34 form the addresses of the second memory block (raster memory) —connections 65 and 66. Additionally, the addresses generated by counters 32 and 33 are used with control unit 5 and 6 of the 4-character generator (connections 65 and 63).

The control unit 9 implements three modes of operation of the device.

The mode number that is currently being implemented is recorded from the output of the information system to register 14 (connection 30) at its first input.

Register 14 is reset by a signal from the information system at its second input (connection 31) every time it switches to a new mode of operation.

The device works as follows.

Through register 3, character codes in the exchange mode with the information system (connection 16) are fed to the input of the first memory block 1. Here they are written in successive cells in the order of arrival at its entrance. According to the signals from the outputs of the control block 9 in the mode of formation of a raster, they are selected from block 1 and pass alternately through register 3 into the 4-character generator.

From the output of block 5 of the permanent memory, codes corresponding to the raster of television decomposition of symbols

34 (connections 64 and 67) and outputs are re-50 into raster line driver 6 of the horn 14 (connection 27) are fed through it and register 3 into the second to the inputs of the decoder 35 connected to memory block 2 to block 36 constant this memory.

In the raster regeneration mode, information words with the length kxm of bits go through register 3 from block 2 to block 7 (k is the number of characters per line, m is the length of the line video code of one character).

Using the block 36, in which the microinstructor codes are recorded, the signals Record, Read and Reset (connections 37.51 and 56) of all the main units of the device, lower case (connecting

53) and frame (connection 52) synchronization pulses, blanking signals of the return beam codes in lines (connection 55) and frames (connection 54), readiness; l, receive code (connection 57), carry pulses arriving at counter 33 from counter 32 (connection 58), reset pulses of block 9 (connection 59) and reset pulses of the backlight unit 7 (connection 60).

Counters 32 and 34 form the addresses of the first memory block (symbol memory (

fishing) - connections 63 and 66, counters

33 and 34 form the addresses of the second memory block (raster memory) —connections 65 and 66. Additionally, the addresses generated by counters 32 and 33 are used to control blocks 5 and 6 of the 4-character generator (connections 65 and 63).

The control unit 9 implements three modes of operation of the device.

The mode number that is currently being implemented is recorded from the output of the information system to register 14 (connection 30) at its first input.

Register 14 is reset by a signal from the information system at its second input (connection 31) every time it switches to a new mode of operation.

The device works as follows.

Through register 3, character codes in the exchange mode with the information system (connection 16) are fed to the input of the first memory block 1. Here they are recorded in successive cells in the order of arrival at its input. According to the signals from the outputs of the control block 9 in the raster shaping mode, they are selected from block 1 and pass alternately through register 3 into the 4-character generator.

From the output of block 5 of permanent memory, the codes corresponding to the raster of television decomposition of characters enter 50 raster line generator 6 and, through it and register 3, into the second memory block 2,

In the raster regeneration mode, information words with the length kxm of bits go through register 3 from block 2 to block 7 (k is the number of characters per line, m is the length of the line video code of one character).

In block 8, the image is displayed on the screen.

If necessary, the mode of exchange with the information system in the cells of the first memory block 1 records a sequence of character codes of the rows of keys of one of the keyboards, the need for which has arisen at a given time. This sequence of codes corresponds to some conditional text. In this text, the rows of keys play the role of lines.

When performing other modes in block 8, an image of the selected keyboard appears. The images of the keys appear in those parts of the screen which, due to the optical communication, are in one-to-one correspondence with the sensor sensors of the unit 10.

When working with such a keyboard, the pulses from the outputs of block 10 are received at the second input of the encoder 12.

From the output of block 12, the codes corresponding to the keys are input to the register 13, from its output they are transmitted to the input of the information system.

Each key of the keyboard and each touch sensor in the encoder correspond to a separate code that allows them to be recognized.

Codes from the output of the register are transmitted to the information system by a signal of the code (connection 18). Upon receipt of a code, the information system drops register 13 (connection 7) and waits for the occurrence of the next code in register 13

From the output of the information system, character codes can be transferred back to the device through its input (connection 16). The code is recorded after the information system receives the signal C from the output of the comparator unit 15, which is used to compare the current readings of the counters 32 and 34 of the control unit 9 with the address at which the character coming from; information system.

Thus, replacing the contents of the character storage (the first memory), you can easily rebuild and adapt the keyboard for. each case. It is possible to automatically change the image of characters on individual keys according to the program, thereby expanding the information exchange.
