Description

The invention relates to automatics and computing, in particular to devices for controlling the format of printing information.

A device for controlling the format of an information print is known, which contains a reading device that converts data stored on a punched tape in the form of holes (holes) into corresponding levels of voltages. The reading device consists of a reading head and a die of perforated tape position codes. The reading head consists of a table and a photoelectric reading unit located on it, a stepper motor with a gear roller fixed on its axis, in a driving punched tape, a folding arm with an illuminator node in which electroluminescent diodes are used, and a clamping mechanism. The print format is set by the information printed on punched tape 1.

The disadvantages of the known device are the high cost of the equipment used, the complexity of the design and low reliability due to the use of a large number of electromechanical elements.

The closest in technical essence to the offer is a device for controlling the printing format of information, containing a signal sensor, the output of which is connected to the first input of the element AND and through the first delay element to the second input of the element And, the output of the bridge is connected to the first input of the register

10 position codes and with the input of the second delay element, a switch, the output of which is connected to the first input of the counter, the outputs of which are connected with the inputs of the NAND element,

25 of the signal sensor coupled to the paper feed shaft of the printing device. The value of these codes is equal to their serial number in the sequence of codes from 1 to 30 12 С 21. The functional capabilities of this device are limited, since it does not allow the use of arbitrary information printing formats, i.e., such formats that are characterized by a sequence Binary four-bit position codes following one after another in arbitrary order at irregular intervals, multiples of the repetition period of pulses taken from the output of the sensor signals. The purpose of the invention is to expand the scope of the device. The goal is achieved by inserting a Format task block, a memory block, a trigger, NOT elements and AND-OR-NOT into the device, and the output of the second delay element is connected to the first input of the memory block and through the NOT element to the first input of the AND element -GET NOT, the second. the input of which is connected to the first output of the format specifying unit; the second, third, fourth, fifth and sixth outputs i oToporo are connected to the second, third. Fourth, fifth and sixth inputs of the block of the fourteen, seventh and eighth inputs of which are connected to the third and fourth inputs of the AND-OR-NOT element and with the trigger outputs, the first input of which is connected to the first input of the counter, the second input of which is connected to the second input of the trigger The output of the AND-OR-NOT element is connected to the third input of the counter, the outputs of which are connected to other inputs of the memory block whose outputs are connected to the other code in the position code register. The drawing shows the block diagram of the device. The device contains a sensor 1 signal, the first element 2 delay, element 3, the second element 4 delay, element 5, element AND-OR-NOT trigger 7, switch 8, element Y-HE 9, counter 10, unit 11 pa mti, register 12. position codes and block 13 setting format. The device works as follows. When the switch button 8 is pressed, the seven-digit binary counter 10 is reset, and trigger 1 is set to one. In the initial state, the value of the counter 10 is zero. The state of the trigger 7 determines the operation mode of the memory block 11. The single state of the trigger 7 sets the recording mode of information in the memory block 11, and the zero information playback mode at the outputs of the memory block 11. The information recorded in the memory block 11 comes from the information outputs of the block 13 for setting the mat as a binary four-way sequence; the spreading codes gated by the recording signal are sent from the output block 13 of the format to the corresponding control input of block 11 ti. Memory unit 11 is sequentially located four-bit memory cells. The information recording press produces sequential filling of block cells with BceJt information. 11 memory, starting with zero and ending seventy first, in addition. The cell addressing is performed by modifying the counter 10, the control outputs of which are connected to the corresponding address inputs of the memory block 11. The pulses modifying the value of the counter 10 are received from the control output of the block 13 of the DEFINITION format, the input of the counter 10 through the AND-OR-NOT element. Three, when the counter 10 reaches the value 72, the process of filling the information of the memory block 11 is completed. This causes the reset of the counter 10 and the trigger 7, due to the coincidence of the J high levels of voltage on the inputs of the element EI-YE 9. Thus, the information playback mode is established, due to the zero trigger 7. In this mode of operation the device, from the electromechanical sensor 1 of the signals coupled to the rotating shaft of the paper floor, impulses are received at the input of the first delay element 2 and which simultaneously arrive at the input of the AND 3 element. At the other. the input arrives pulses from the inverse output of the first element 2 delay. Hs in the gateway of the element 3, pulses are obtained, post-entry to the input of the second element 4 delays, from the inverse output of which short pulses are removed. These pulses, via the elements NOT 5 and d-or-NOT b, modify the value of the counter 10, and also initiate reading of information from the cells of the memory block 11. After interrogating the 7.2 cells of the memory block 11, the counter 10 is reset to its initial state. The reading process is then cyclically repeated. The codes read from memory 11 during the operation of the printing device are written into a pre-reset register 12 codes, positions. The print format of the device is specified by a set of binary four bit codes recorded in block 11 of memory — it can be any, depending on the combination of codes in this combination. This provides high flexibility in managing the printing of information in printers.
