Description

The invention relates to the field of computational technology. And it can be used as a device for outputting information to a punched tape.

On the main / auth.St. No. 479129, a device for registering information is known, comprising a register, the outputs of which are connected to one of the inputs of the row allocation unit, and a tape punch, the outputs of which are connected to the control unit and the registration prohibition unit, and the inputs through 6.POK registration prohibition to the outputs of the unit the rows, the KoivwyTatop rows, whose inputs are connected to the control unit, and the outputs to the other inputs of the row of the HZ rows.

A disadvantage of the known device is the sequential output of information from the register to several lines of punched tape, regardless of the contents of the register.

The aim of the invention is to improve the speed of devices puttl soyratseni time output when outputting arrays of numbers with a variable number of significant bits.

The goal is achieved by the fact that;

OR, encoder and comparison unit, the output of which is connected to one of the inputs of the control unit, additional register outputs are connected to the inputs of the OR elements, the outputs of which are connected to the inputs of the encoder, the outputs of which are connected to the inputs of the first group of the comparison unit, the inputs of the second group of which are connected to the outputs

10 switch rows.

figure 1 shows the functional diagram of the device for recording information; in Fig. 2, the perforations of numbers, different in size, on the per15 side of the P L-150.

The device contains a register 1, a block for allocating lines 2, a block of 3 keys, a perforator 4, a switch 5 lines, a control block 6, a block 7 for comparison,

20 encoder 8, elements OR D -9.

The device for recording information is working in the following way.

The process of outputting a binary number to the punch starts with the Start command. Before the arrival of this command, the device is in a wait state. In this case, the perforator 4 is turned off, the clock pulses from the output of the perforator 4 are fed to the first 0 (synchronizing) input of the control unit 6, without affecting the operation of the device. -

On the Start signal, the binary code of the number output to the perforator is written to register 1, and at the same time this switch sets the switch 5 lines to the initial zero state. An input to the third input of the control block b. The start signal sets it to the state that allowed the synchro pulses of the perforator 4 to pass through the control block 6 to the counting input 5 of the line. Simultaneously, the control unit 6 generates from the synchro pulses 4 a line punching signal from the second output of the control unit 6 to the input of the key block 3, and a tape transport signal received from the third output of the control block b to the input of the perforator 4. The outputs of register 1 are split into several groups (lines) in several bits in each. The number of bits in the group (row) is determined by the number of tracks allocated to the field of the number displayed on punched tape. Since the number of bits of the output binary number is several times larger than the number of tracks on the punched tape, the output number is punched into several lines. The number of rows for heterogeneous numbers is different. To select the first younger line, one track on a punched tape is assigned to the sign of the beginning of a word. The perforation of numbers of various sizes on the PL-150 perforator is shown in FIG. From the outputs of register 1, the recorded binary code goes to the inputs of block 2 for selecting a line and to the inputs of elements OR 9, the number of which is one less than the number of groups (lines) into which the input number is divided. At the output of the element OR 9, a single signal appears in the event that the code of the corresponding string is not zero. The encoder 8 converts the code generated at the output of the element OR 9 into a binary code of the number of high-speed lines. After the start signal, the sync pulse of the perforator 4 passed through the control block b to the counting input of the switch 5 lines sets it in a position that permits the output of the row selector 2, the first line code and the signal of the beginning of the word to enter the block 3 keys. A word start signal is generated in the row selection block 2 by deciphering the state of the switch 5 lines. From the second output of the control unit 6, the line perforation signal, formed from the sync pulse of the perforator 4, receives the control input of the Block 3 keys and allows the check code to enter the perforator 4 and its perforation. From the third output of the control block b to the control input to the perforator 4, a tape transport signal is delayed relative to the perforation signal.

Thus, the process of extracting the first row ends with perforation.

code and shipping tape.

The output of the second and subsequent lines is determined by the result of comparing the input codes in block 7 of the comparison, which compares the code at the output of the switch 5 lines with the output code of the encoder 8. At the output of the encoder 8 there is a code corresponding to the number qTpoK to be output, and the switch’s output of 5 lines contains a code corresponding to the number of lines to be extracted, and the switch’s output of 5 lines contains a code corresponding to the number of lines already drawn

lines. In the case of equality of these codes, a signal is output at the output of the comparator block 7, which enters the input of the control block b and prohibits the passage of the sync pulses of the perforator 4 to the input of the viutor of 5 lines. and also prohibiting the formation of perforation and transport signals in the control block b. Thus, in the case of equality of the codes of the COP 1paratora 5 lines and the encoder 8, the device enters the mode of waiting for the next pulse Start In case of inequality of the codes of the CC of the 5 lines and the encoder 8 signal

At the output of block 7, a comparison does not occur. The second after the impulse start the synchroil pulse of the perforator 4 passes through the control unit 6 to the input of the co-switch 5 lines and

sets it to state 2,

which leads to the appearance at the output of block 2 of the selection of lines of code of the second line. The process of perforation and transportation of the tape is repeated. The described operation cycle of the device will be repeated: repeat until the switch codes of 5 lines and the encoder 8, i.e. until all meaningful (non-zero) lines of the displayed number are output.

The use of the proposed device leads to a reduction in the time of information output from various sources, an increase in the service life of the perforator, and a decrease in the consumption of punched tape.
