Description

This invention relates to devices for automatically separating words when printing process information.

The purpose of the invention is to increase the efficiency of word separation by improving the accuracy of the transfer.

FIG. 1 is a block diagram of the device according to the invention; FIG. 2 is a block diagram of the control unit.

The device contains the first register 1: the memory of words, the first input of which is the first input 2 of the device, depotraser 3, control block 4, the second 5 and third 6 word memory registers connected in series.

The output of the third register 6 of memory is the first output 7 of the device, the Input 8 of the decoder 3 is connected to the first input 9 of the second register 5 of the word memory and connected to the output of the first register 1 of the word memory.

IlepiabM and the second outputs of the decoder 3 are connected respectively to the first 10 and second 11 inputs of the control unit 4.

The third output of the decoder 3 is connected to the third input 12 of the control unit 4 and connected to the second 13 output of the device.

The output of control unit 4 is the third output 14 of the device.

The second input of the first register of the word memory is connected to the second inverse inputs of the second 5 and third 6 word memory registers and is connected to the second input 15 of the device. The zeroing inputs of the first 1, second 5, and third 6 word memory registers and the even input of control unit 4 are interconnected and are connected to the third input. 16 devices.

The control unit 4 (FIG. 2) has a memory register 17 containing the first 18, second 19, third 20, fourth 21 triggers, first 22, second 23 third 24 AND elements, OR element 25. The first 18 and second 19 outputs of the flip-flops are connected Respectively, the first and second inputs of the first element are AND 22.

The output of the second element And 23 is connected to the second input of the third flip-flop 20, the output of which is connected to the second input 11 of the control unit 4. The output of the third element And 24 is connected to the second input of the fourth flip-flop 21, the output of which is the output 14 of the control unit 4.

The first inputs of the first 18, second 19, third 20, fourth 21 memory register trigger 17 are interconnected and connected to the output of the OR element 25, the first and second inputs of which are the third 12 and fourth 16 inputs of the control unit 4, respectively.

The device after switching on works as follows.

Before starting the operation, the device is reset with the signal of the unit at the third input 16 of the device reset.

In this case, the first 1, second 5 and third 6 word memory registers and control unit 4 are set to the initial zero state.

The operation of the device begins three characters to a predetermined format and, with an analysis zone of four symbols, is performed in four cycles of operation of the device.

The character codes from the keyboard or from the code carrier arrive at the first 2 information input of the device.

The character code is inserted into the first register of the word memory 1 at the leading edge of a single clock signal at the second 15 input of the device.

The falling edge of a single clock signal transmits the character code received in the first memory register 1 via the first input 9 to the second memory register 5. At the same time, the contents of the second register 5 of the word memory are automatically moved to the third register 6 of the word memory to the first output 7 of the device.

The character code stored in the first memory register 1 is supplied from the output of the first memory register 1 to the input 8 of the decoder 3.

The Decoder 3 performs the decoding of the code of the group of the sign (vowels, consonants) entered in the first memory register 1, as well as the decoding of the end of the word recognition, i.e. space or carriage return code. When deciphering a consonant from the first exit decryph31

RATOR 3 to the first input 10 of control unit 4 receives a signal of a logical unit. When a vowel mark stored in the first register 1 of memory is decrypted, the signal of the logical unit is formed at the second output of the decoder 3 and is fed to the second input 11 of the control unit 4.

When the word end feature code is decrypted, the logical unit signal from the third output of the decoder 3 is fed to the third input 12 of control unit 4 and simultaneously fed to the second output 13 of the device.

The control unit 4 is a control automat having

the four inner states are Y,, Y,,

Y2. W.

The table shows the state of the control unit and the following notation is used: C1 and C2 are consonant signs of the first and second syllable in the transfer zone, respectively; G1 and G2 - vowel signs, respectively, of the first and second syllables, J P - separation signs; PKS - space, carriage return, and-short, XI ,. X2 and X3 - the inputs of the control unit, respectively, the first, second and third.

Od is the initial, zero state j Y, is the first phase state of control block 4, it is set when the control unit 4 arrives at the input of the first vowel or consonant sign in the line end zone. The transition of the control unit 4 to the state Y corresponds to the appearance of the signal of the logical unit at the first or second input of the first element I 22,

Y is the second phase state of the control unit 4; it is set when the combination S1G1 or G1C1, which constitutes the first syllable, arrives at input 2 of the device. The transition of control unit 4 to the second phase state Y corresponds to the appearance of a signal of a logical unit at the output of the first element 22.

UZ is the third final phase state of the control unit 4, it is determined by the presence of two syllables in the zone of possible transfer, with the second syllable beginning with a consonant sign (combination C2 and G2).

The transition of control unit 4 to the fourth phase state is described by the following equation.

(t, lAX.2 ((tj) AX2 (i4) VX2 (t, hxUi2 l l (tj) X2 (t4,

de X1 (tj) is a signal of a logical unit at the first 10 input of control unit 4 in the i-TOM device operation cycle

This phase state Y causes the appearance of a signal of a logical unit at the third output 14 of the device and the formation of an attribute of the automatic transfer commagie. At the same time, the characters of the word carried to the next line are stored in the third 6 and second 5 registers of the word memory.

The presence in the zone of possible transfer of two syllables is extremely necessary, since a situation is possible when, after typing the first syllable, one letter from the word remains. In this case, the transfer is invalid. If within four cycles of viewing the transfer zone, the first input 2 of the device receives a space or carriage return code, control unit 4 will go to the initial zero state Y (see table) of control unit 4 states.

At the second output 13 of the device, a signal of a logical unit is displayed, which is a sign of automatic line termination without transfer.

In this case, the last character of a word or punctuation mark is transmitted: at the end of the current device operation cycle, to the third register 6 of the word memory to the first output 7 of the device.

Since the symbols b, b, and do not belong to either vowels or consonants, then, when they get into the zone of transfer of these signs, the state of control block 4 does not change.

In this case, the information stored in the memory registers is automatically moved one position in the direction to the first 7 output of the device.

In this case, the device may end the line, for example, based on the end of the word, but the signs and, b .b will not be transferred. To another line

(No. 7 of the state table of the control unit 4).

If, during the four cycles of viewing the transfer zone, the signal of the logical unit does not appear on either the second or third outputs of the device, the device is blocked and the line is terminated by the operator, for example, L / L /

measures at the end of the word closest to the specified string format.

Using the device reduces the number of errors when transferring words from one line to another.

The use of this invention increases the efficiency of word separation by increasing the accuracy of the nose.
