Closest to the proposed technical entity is a device comprising a marker movement keyboard, an alphanumeric keyboard whose information output, as well as the output of the marker position comparison unit is connected to the control unit, the output of which and the marker position counter output are connected to the position comparison unit inputs the marker, in addition, the device contains a group of elements And connected to the match block associated with the block of code character matching, the code feature analysis block connected the control unit and the match unit, the block, the fall and the block / character code comparisons are associated with an alphanumeric keyboard 2. The known device does not allow for editing to "imprint whole messages consisting of several words with automated movement the marker from one side to the other by a single pressing of the control, which limits the speed. The purpose of the invention is to increase the speed of the device and expand the scope of application by providing the output of the marker to the pre-determined screen familiarity. The goal is achieved by the fact that the device containing the keyboard for moving the marker, the first OR element, the first counter and the marker position comparison unit, the control unit connected to the alphanumeric keyboard and the marker position comparison unit are inserted into the device for forming the a priori data array and connected in series the second element OR, the first generator of single pulses, the first trigger trigger, the first element AND, the second counter and the first decoder connected to the first trigger OSCAL, the first and second counters, a control unit connected to the first AND gate, a first OR element connected to the a priori data array generating unit, which is connected to an alphanumeric keypad, a second OR element, the control unit and the first single-pulse generator. The array of prior data contains a third element OR, a second single pulse generator, a second start trigger, a second element AND, a third counter, a second descriptor whose outputs are connected to control inputs of valve groups by the number of rows whose outputs are connected to the second element OR, the installation output of the second descrambler is connected to the second inputs of the second trigger trigger and the third counter, the inputs of the fourth element OR and the information inputs of the valve groups by the number of rows n Connected to the switch. As a result, the device obtained a significant increase in speed and expansion of the application area by ensuring the output of the marker to the pre-determined screen familiarity and automation of the following operations: typing tabular data on the line; output marker on the next line to be edited; forming a command to send a typed message upon completion of the table.

FIG. 1 shows a diagram of the proposed device; in fig. 2 is a block diagram of the formation of an array of a priori data.

The device contains an array of a priori data forming unit 1, an alphanumeric keyboard 2 consisting of a typed floor of buttons 3 and an encoder 4, a marker movement keyboard 5, a control unit 6, a marker position comparison unit 7, a control group of outputs 8 of the device, information a group of device outputs 9, an address group of device outputs 10, the second element OR 11, the first generator 12 single pulses, the first trigger 13, the first element AND 14, the second counter 15, the first decoder 16, the first counter 17 and the first element OR 18.

Block 1 contains the third element OR 19, the second generator 20 single pulses, the second. trigger 21, the second element AND 22, the third counter 23, the second decoder 24, the valve groups of the first row 25i, the second row 25, and so on, the nth row 25p, the fourth element OR 26, the switch representing switch 27.

The device works as follows

In the control unit 6, the clock frequency from the clock generator enters the counter input. The output of the time counter is connected to a time counter decoder, at the outputs of which a pulse sequence is generated, which ensures the reception of the sign code, its recording to a specific address of the FIZM and preparation for receiving the next sign (cycle).

The time counter determines the time required to edit a single character. Having completed the processing of a character one-by-one, the time counter decoder increases the synchronous code contained in the familiarity counter and the address counter of the ferrite random access memory by the last clock by "1, sets the time counter to" O and starts processing. sign, found on the next familiarity.

The recording of the mark in the FOZU is carried out. in the place indicated by the marker. The control of the marker during cognitive editing is carried out using the keyboard 5 of the movement of the marker, the control signal with which, when the keys are pressed, increases by one the contents of the first counter 17.

The code from the counter output of the familiarity block upright 1 enters the input of block 7 to compare the positions of the marker. The impulse from the output of the decoder of the control unit polls the element AND of the control unit connected to the output of the unit 7 to compare Marker positions. When the codes on the counter familiarity of the control unit and on the first counter 17 are equal, the signal from the output of the AND control unit is fed to the input of the AND element of the control unit.

After the familiarity counter of the control unit calculates the all-familiarity, a pulse of the end of the frame is generated at its output, which marks the familiarity counter, r, and a new frame begins. Thus, the comparison pulse at the output of the control unit AND element is generated once per frame.

To ensure accelerated input of a priori data, the operator sets the switch to the required position, which is a sign of the choice of a specific data packet and an initiative command to turn on the device. Further, the device, without further intervention by the operator, provides for editing the message corresponding to the given position of the switch, with each message character being edited for one frame, and the first message character is typed into the place originally indicated by a token

0 start the editing process.

After the first character is written to the FOSU numeric register, the device moves the marker to the next familiarity, starts writing the next character to the new position of the marker, etc. After editing the line, the device automatically moves the marker to the beginning of the next line and further editing is done next

0 lines. Upon completion of editing the message, the device generates a command to send the typed message. These functions are provided by the proposed device for editing alphanumeric information.

When the operator sets the switch 27 to the desired position, a potential signal is output from this element, coming through the third element OR 19 at the input

Q second generator 20 single pulses. The second input of the second single pulse generator is connected to the clock pulse generator of the control unit 6. A single pulse generator 20, based on a potential signal from switch 27, generates a pulse, which sets to "1 second trigger 21, the output of which grants permission for the clock to pass from the clock generator of the control unit through element 22 to the third counter 23. Outputs the counter 23 is connected to the inputs of the second descrambler 24. The pulse from the first output of the decoder 24 of the block 1 is fed to the inputs of the elements of the 1st row 25 group of the valve,;. to the second input of one of the elements of this

The group 5 receives a signal from the switch 27; therefore, only the valve group element corresponding to the given switch position, i.e., the corresponding sign, which is to be edited in the first line at the location indicated by the marker position, is triggered. The received signal from the output of the valve group of the first row 25 (arrives at the input of the h (of the solid OR element 26 of the a priori data formation block 1 corresponding to the sign currently displayed on the screen. Signals of the same signs, included in various messages, regardless of where their edits are combined on the OR element 26, the outputs of which are also connected to the outputs of the button 3 keypad switches corresponding to a given sign, which makes it possible to carry out both cognitive editing and and accelerated editing when introducing a priori data. From the output of the OR element 26 of the array of a priori data forming unit 1, the signal simultaneously arrives at an encoder 4, where it is converted into a sign code, and also through the element OR 11, to start a generator of 12 single pulses. 12 single pulses sets to "1 flip-flop 13, from the output of which element 14 goes to the passage into counter 15 through this pulse element of the end of the frame generated by control unit 6. The outputs of the counter 15 are connected to the inputs of the decoder 16. An impulse from the first output of the decipher 16 sets to "1 the editing trigger and the trigger of the sign of the control unit. The output of the edit trigger outputs the permitting potential to the input of the control element AND block. If the codes on the counter are familiar, the control unit 6 and the counter 17 at the first input of the AND element of the control unit 6 appear a potential signal. At the moment the control signal of the control signal from the decoder at the output of the element I arrives at the second INPUT, a coincidence signal is generated. This signal is transmitted to the second input of another himept AND control unit, at the output of which a signal appears that sets recording mode to 1 trigger in ferrite random access memory. From the output of the sign trigger to the input of the element group, And the resolving potential is fed to the second input of the element group. And - the sign code from the encoder 4. As a result, the sign code from the encoder 4 is fed to the input of the group of elements I. Since the trigger of the write mode in the FIZM is set to “1, then from its output the permission to the group of elements And to the the location of the sign code on the installation inputs of the numeric register of the control unit. The next clock pulse from the decoder of the control unit through the And element, opened on the second output by the trigger of the write mode in the FZU, synchronizes the writing of the sign code to the numeric register. In addition, the impulse from the output of the I element sets in "On the edit trigger and the trigger of the sign of the control block. The code from the head register of the control unit through the AND group of elements opened by the second input by the trigger of the write mode to the FOZU is fed to the installation inputs of the numerical register of the Foz. The next clock pulse coming from the decoder through the element I, to the second input of which the resolving potential comes from the trigger of the write mode in the FZD, synchronizes the rewriting of the sign code from the numeric register to the numerical register of the FIZ, whose outputs are a group of information outputs of the device 9. Address FOSU cells (group of outlets 10) at the same time correspond to the position of the marker on the screen of the cathode ray tube, since the recording is carried out during one cycle of the time counter operation if the code is equal In the counter, the familiarity of the control unit and the counter 17. From the output of the control unit's decimator, a pulse is sent to the setting “On the trigger of the write mode in the FOZU, the next clock pulse is used to increase the code in the familiarity counter and the address counter to” 1, i.e. next address. With the last clock from the decoder, the time counter is set, in "O. Thus, the first character of the input a priori data is edited, and after a predetermined time interval, the decoder 24 of the next character of this line is output from the decoder 24 of the a priori data array 1 to the valve group of the first row 25. After editing the last character of the line, the impulse from decipheror 24 enters through the element OR 18, sets on the counter 17 the code of the position of the marker corresponding to its location at the beginning of the next line. The outputs of this group of elements of the bit combination of the element OR 18 are connected to (p-1) outputs of the decoder 24, and the elements of the OR group 18, corresponding to the bits of the counter 17 set by the signal from the decoder 24 to the unit state, are connected to the forward output of the decoder 24, and the corresponding bits of the counter 17, which are set to the zero state, to the inverse output of the decoder 24. In the next cycle, the signal from the decipheror 24 of block 1 is sent to the next group of valve groups. Similar to the above, all subsequent characters of the message are edited before the completion of the prior data table. At the end of the accelerated editing process, the device generates a sending command. When editing information character by character, the operator sequentially produces a set of input characters on the button keyboard. After editing, the operator, with a view to sending information entered via the keyboard into the system, enters a control signal from a button switch, which is fed to the encoder 4 and converted into an eight-digit code that is issued to the system. With accelerated editing, upon completion of filling the table of a priori data from decipher 24, a signal is output to the element OR 26. The second input of this element OR is connected to the output of the push-button switch that commutes the signal forming circuit to send information to the system entered on the screen during character-by-character editing. The signal from the decoder 24, passed through the OR element 26, goes to the encoder 4, where it is converted into an eight-bit send command code intended for reception into the system and outputted to the group of control outputs of the device 8. Thus, accelerated editing of a priori data and automated formation of the command to send data to the system.
