Description

The invention relates to devices for reproducing texts and can be used in polygraphy when typing texts for printing.

A device for reproducing texts containing input data output nodes and a control node 1 is known.

A disadvantage of the known device is the complicated structure of aligning print lines in length.

FIG. 1 shows a block diagram of the main components of the proposed device for the reproduction of texts; in fig. 2-

A general block diagram of a device that depicts the main control units and their communication with each other.

The device contains: green / data entry; node 2 you data; control unit 3.

The control unit includes: control unit 4; unit 5 memory units; decipher 6; key scheme 7 konstastroki; address register 8; key scheme 9

intervals; buffer memory block 10; block // data memory; gating unit 12; block 13 correction intervals.

The data entry node /. Through the first input of gating unit 12, memory unit 11

data, input block 10 buffer memory

connected to the data output node 2 and through the decoder 6, the first input of the unit.5 memory unit, the control unit 4 and the address register 8 is connected to the data memory unit /./. The second output of memory block 5 is connected to the first input of the key circuit 9 of the intervals, the output of which is connected to the first input of the interval correction block 13, to the second input of the control block 4 and to the memory block of 5 units. The block 10 of the buffer memory h, through the block, 13 interval correction is connected with the second input of the gating unit 12, the output of which is connected to the third input of the control unit 4 through the key circuit 7 of the end of the line, the second output of the block 10 of the buffer memory is connected the second input of the key scheme is 5 intervals.

After start-up, the device operates as follows.

Encoded letters get from the node / data entry through the gating unit 12 to the data storage unit 11, and the destination of this data is specified by the address register 5. The data from the node / data entry goes simultaneously to the decoder 6, where the number of units is determined appropriate for printing the length of the line. This number of units is issued in the unit 5 memory unit, in which they are stored in summarized form and in which the current balance is then formed in units, namely as a function of the current value of the string length relative to the specified value of the string length. Data may be entered into the data storage unit // until this unit, the capacity of which, as a function of the length of the line specified for this work, can be adjusted, will be filled and will not give a signal about it.

If the sum of the units decrypted from the entered letters coincides with the predetermined number of odnits, then the line length alignment is not performed. The end of the line is determined by the key circuit 7 of the end of the line, which generates the corresponding signal. The data from block 11 is sent by the block of control 4 via the block 10 of the buffer memory as a whole line by the node 2 of the data output. If the length of the line entered into the data block 11 of the data does not reach the predetermined value, and the key scheme, the 7 end of the line generates a signal that signals the end of the line, to the 4 uyra block, then the memorized data in the block / I / data memory. This process is controlled by the address register 8, and it passes along the path from the data storage unit // through the buffer storage unit 10, the offsetting unit 13 and the spacing unit 12. Data entering block 10 of the buffer memory is monitored

 scheme 9 intervals. If a letter corresponding to the length of the interval is perceived, a command is sent to the interval correction block 13, causing the interval to be extended by one unit, and this command is simultaneously sent to the unit 5 memory unit, which also increases the sum of the stored units by one unit . If block

When 5 units of signals give a signal about their filling, then the interval correction stops when the data. Under the action of the control unit 4, the address register 8 continues to move,

until key scheme 7 of the end of the line perceives reaching the end of the line. At this point, in block 11 of the data memory, there is a text with the corrected line length and in such order that

It is possible to start the output of data through the block 10 of the buffer memory in node 2 of the output. At the same time, it is possible to enter new data, i.e., the next, line through the node / data entry.

You can also enter data into block 11 of the data memory and after. outputting a filling signal of 5 units of memory. In this case, it is possible to undertake a polymeric discarding until the specified length of the string is obtained with or without correction.
