This invention relates to electrographic devices.

An electrographic device is known that contains an image exposure unit connected via a power supply unit to a mode control unit that is connected to an electric drive and a converter connected by input to one output of the sensor unit, and output to the information input of the image exposure unit tl.

A disadvantage of the known device is low productivity.

The purpose of the invention is to increase productivity.

This goal is achieved by the fact that an electrographic device containing an image-exposure unit, connected via a power supply unit to a mode control unit, which is connected to an electric drive and a converter connected

INPUT to one output of the sensor unit, and the output to the information input of the image exposure unit, has a switch unit and a calculator, while another output of the sensor unit is connected to the first input of the switch unit, the second input of which is connected to the output of the calculator connected by its inputs to information outputs of the converter, which the control input is connected to the output of the switch block.

The drawing shows a functional diagram of the electrographic device.

The device comprises an exposure and imaging unit 1 connected to power supply unit 2 and drive control unit 3 k. The control unit 3 has two inputs, the first and second control inputs. The 5-mode control unit and the sensor unit 6 are connected respectively to the first, second and third inputs of the converter 7, and the second output of the sensor unit 6 is connected to the third input of the converter 7 via the switch unit 8. The information outputs of converter 7 are connected respectively to the input of the exposure and image drawing unit 1, the second control input of drive control unit 3 k and simultaneously with the inputs of calculator 3, the output of which is connected to the input of switch block 8,. The drive contains node 3 control and drive 4. The electrographic device operates as follows. When the Charging button is pressed on the mode control unit 5, the voltage from the power supply unit 2 is supplied to the exposure and image drawing unit 1 and through the mode control unit 5 to the first input of the drive control unit 3 4. At the same time, the electrical signals from the sensor unit 6 do not appear and only charge the surface of the recording medium of the unit 1 exposure and application of the image. When the Record button is pressed on the mode control unit 5, the voltage from the power supply unit 2 supplies9; to the unit 1 of exposure and deposition of the image and through the unit 5 of the mode control to the first input of the drive control unit 3. At the same time, through the mode control unit 5, the voltage is applied to the first inputs of the converter 7, the second and third inputs of which receive electrical signals, respectively, from the first and second outputs of the sensor unit 6. In this case, the electrical signal. From the first output unit 6 of the sensors through the converter 7 is fed to the second control input of the drive control unit 3 k, and the electrical signal from the second output of the sensor unit 6 through the switch block 8 and the converter 7 enters the display and imaging unit 1 . Both information outputs of the converter 7 are electrically connected to the inputs of the calculator 9. In this case, in block 1 of the exposure and application of the image, an electronic static image of the flight route is continuously formed, i.e. The exposure process is performed, and the calculator 9 continuously compares the current values of the flight route parameters received from the information outputs of the converter 7 with the specified values embedded in the accumulator of the calculator 9. In the event of a discrepancy of one or two of these values, an electric output occurs at the output of the calculator 9 the signal that enters the block 8 Under the influence of this signal, the block 8 operates and with a certain periodicity switches the electrical circuit of the second output of the block of 6 sensors, as a result those which record flight route in block 1 and applying an image exposure is performed by a dotted line. As soon as the flight route parameters enter the specified limits, the electrical signal at the output of the calculator will disappear and the recording of the flight route will again be performed as a continuous line. When the Print button is pressed on the mode control unit 5, the voltage from the power supply unit 2 is supplied to the exposure and image drawing unit 1 and, through the unit 5, to the first input of the drive control unit 3 k, while no electrical signals are received from the sensor unit 6. In block 1 of exposing and applying an image with a strict technological meal, a recording of the flight route on a paper tape is formed, i.e. the image drawing process takes place. When the Cleaning button on block 5 is pressed, the voltage from power supply unit 2 is fed to the first input of drive control unit 3. The drive rotates the recording medium of exposure and imaging unit 1 simultaneously driving its cleaning unit, which removes residues with its fur brushes the developing element from the surface of the record carrier. The application of the proposed electrographic device makes it possible to determine whether the actual flight route deviates from the given one and, thus, reduces the labor costs required for decoding the flight route record.
