Description

This invention relates to telegraphy and can be used in electromechanical or electronic telegraphs. devices. A telegraph receiver receiver 5 is known, containing a series-connected receiving-dialer unit, a control unit and a reperforator, combined with the inputs of the printing unit, the second input of which is connected to the electric drive, ao and the sensor of the axis of the electric drive whose outputs are connected respectively to the input receiving The keypad and the other input of the control unit 1. However, the well-known receiver contains a small number of mechanical assemblies, which complicates its design and reduces reliability. The purpose of the invention is to simplify the device by reducing the number of mechanical nodes. To this end, a telegraph receiver containing a series-connected receiving unit, a control unit and a reperforator integrated 2 along inputs with a printing unit, the second input of which is connected to the electric drive, and the axis position sensor of the electric drive, whose outputs are connected respectively to the input-type input. A block and a sensor for printing time, a code converter and a block for changing the configuration of characters are entered, and the output of the receiver-dialing unit is connected to the inputs the code generator and the symbol configuration change block, the output of which is connected to the second input of the code converter, the third inputs of which are connected to the outputs of the print torque sensor, the inputs of which are connected to the reperformer and electric drive, and the other outputs of the print torque sensor are connected to the sensor inputs of the axis of the electric drive, and the outputs of the code converter are connected to the inputs of the printing unit. The drawing shows a structural electrical circuit of the proposed receiver. P1) The satellite contains a sensor for 1 position of the axis of the electric drive, a sensor for 2 moments of printing, a control unit 3, a reperforator 4, a printing unit 5, a receiving-dialing unit 6, a code converter 7, an electric drive B and a unit 9 for changing the configuration of characters. The receiver works as follows. The input of the receiver-dial block b is connected to the line through which information is fed to the input of this block.

Block 6 contains a generator of control pulses, a start-stop iriemno-dialing device with a multi-stage accumulator, and it registers the received code combinations and converts them from a serial form to a parallel one. Sensor 1 of the axis of the electric drive determines the moment of reading information from the storage unit to control unit 3.

The unit 3 controls the mechanisms of the apparatus provides control signals to the reperforator 4 and the mechanisms of the service functions of the printing unit 5. Unit 5 with the sign-synthesizing print head is driven from the common electric drive 8. The same functions of the print unit 5 are set in motion. The converter 7 of the information code into the code of the matrix decomposition of characters, in accordance with the received code combinations, outputs at its outputs control signals to electromagnets, the sign of the synthesizing furnace of the attacking head of the block 5. At the same time, the converter 7 will de-encrypt not only the code, but also the register (Russian, lat., numbers) combinations, upon receipt of which the shape of the characters changes (instead of Russian letters - numbers, etc.). Since the matrix decomposition of characters, for example, 7X9 dots, implies the imprinting of characters for nine steps (9 vertical columns), and the quality of the image of the characters depends on the uniform arrangement of the vertical columns of decomposition, the sensor 2 print points, mounted on the axis of the electric drive 8, produces pulses corresponding to the moment of imprinting the character decomposition columns.

At the same time, uneven or unstable rotation speed of the electric drive 8, especially at the time of acceleration of the electric motor when it is turned on by hitchhiking, during voltage or frequency fluctuations, does not affect the quality of the imprint signs, as the sensor 2 print points in this case generates control pulses to the converter code 7 only after a strictly defined angle of rotation of the axis of the electric drive, i.e. after a strictly defined linear movement of the printing unit 5 along the line with a fixed roll of paper a printing device or the paper web relative to a stationary printing unit with znakosinteziruyuschey printhead.

Sensor 2 can be made, for example, in the form of a photovoltaic system for reading information printed in the form of holes or marks on a disk mounted on the axis of the electric drive 8. In this case, the number of holes or the method is equal to the number of vertical columns in the decomposition of characters.

In the case of using a highly stable electric drive, for example, a DC motor with an electric contact regulator, sensor 2 can contain only one mark (hole), which determines the moment of printing start of the next character, and a print moment distributor made on electronic components, for example integrated circuits .

The electric drive 8 uses an electric motor, for example, an asynchronous type with gearboxes, which ensures certain angular speeds of driving the reperforator 4,

mechanisms of service functions, the printing unit 5, corresponding to the time diagram of the work of the blocks and nodes of the receiver. The sensor 1 of the angular position of the axis of the electric drive ensures the coordination of the moments of reading information from the accumulator of the receiving-dialing unit 6. The block 9 of changing the configuration of symbols serves to distinguish the types of information being recorded, for example, when receiving

from two or more sources of information. This difference can be made by changing the slope of the characters. For this, the signals emitted by the code 7 converter on electromagnets

the sign sensor head is delayed by the timing of the driver elements. Turning on or off the time of the driver elements is carried out by signals from block 9. Block 9 changes

configuration of printing characters extracts information about the type of information being recorded, for example, received from a communication channel, or applied from a local device, from information provided

receiving unit 6.

The information received at the input of block b is converted into a form necessary for controlling other nodes and blocks of the receiver, and is read into the code converter 7, the unit 3 controlling the mechanisms of the device and the block 9 changing the configuration of printed characters using the signals provided by sensor 1. Information converter 7 code

In the code matrix decomposition code, the information combinations and register sign combinations are cleared and converted into electromagnet control signals by the sign synthesizing the print head of unit 5. The signal shape, their temporal position is determined by the character decomposition code, for example, 7X9 or 9X12 pixels ( and so on), and the algorithm of the printing unit. Moments of print

The elements of the matrix decomposition of signs are determined by the signals emitted by the sensor 2 print points associated with the axis of the electric drive 8.

The machine control unit 3 decrypts service combinations (space, carriage return, line feed, call, auto answer, etc.) and outputs control signals to the service functions of the printing unit 5 and reperforator 4. Block 9 changes the configuration of printed characters selects control changing the configuration of printable characters from the receiver-dialing unit 6, and issuing a command to the converter 7 of the code for changing the configuration, for example, tilting the font.

A compared analysis of the proposed device and the well-known shows that the proposed device contains less than 200 parts (about 700 parts) and reduces the labor intensity by more than 100 n / h for each product.

Reducing the number of parts and mechanical assemblies, replacing them with electronic units increases the reliability of the product and creates the prerequisites for increasing print speed at least twice.
