Description

The invention relates to instrument engineering and can mainly be used in graphic recording devices in conjunction with information processing devices.

The aim of the invention is to improve the quality of recording information and the grid on an electrically sensitive carrier by automatically adjusting the total current flowing through the writing electrodes, depending on the value of the resistance of the carrier.

The drawing shows a structural diagram of the proposed recording device. I

The device contains a motion speed switching unit and information recording scale, an information recording control unit 2, a power supply source 3, an amplifier 4, an electrically sensitive carrier speed converter 5, keys 6, resistors 7, additional keys 8, decoupling diodes 9 and 10, additional decoupling diodes 1 1, a set of fixed writing electrodes 12, an electrically sensitive carrier 13, a metal roller 14, a tape-testing mechanism 15 controlling the electrode 16, while the recorders 7 and the section of the electrosensitive About carrier 13 through a controlled body clamped to it at the recording time of the electrode 16 and n, the bridge is connected according to a balanced bridge (for the nominal value of the carrier resistance), and its measuring diagonal is connected to the input, amplifier 4, the output of which is connected to the information inputs of additional switches 8 , the control inputs of which simultaneously with the control inputs of the corresponding keys 6 are connected to the output of the block 2, and the outputs of the keys 8 through additional decoupling diodes 11 are connected to the writing electrodes 12, pressed on the recording time to the electrosensitive carrier 13, located on the metal roller 14, is located on the mechanism 15. Power supply 3 is connected to writing electrodes 12 via normally open contacts of keys 6 and isolating diodes 10. Block 5 is connected to output of block 1, and You are 10060. 2

The course through the isolating diodes 9 is connected to the writing electrodes 12.

The device works as follows.

i; When registering information on an electrically sensitive carrier 13, driven by a tape mechanism 15 on a roller 14, the control unit 2 closes the contacts of the keys

10 6) corresponding to the levels of the recorded parameters and the selected recording scale, and the source voltage 3 through them and the isolating ones. . diodes 10 are supplied to the corresponding) 5 uftie writing electrodes 12, creating a certain color intensity of the graphs of the recorded parameters. A coordinate grid with a certain color intensity is created with

20 using converter 5 and drive diodes 9.

At the same time, if the resistance of the electrically sensitive carrier 13 differs between the controlling electrode 16 and the housing from its nominal value, a bridge circuit at the output of the amplifier 4 creates a voltage proportional to the magnitude of their difference, which converts it to the appropriate level of the output voltage supplied through the contacts of the keys 8, locked in phase with the contacts of the keys 6 by the potential from the block 2, and the additional diodes 11 to the same writing electrodes.

Thus, the intensity of the scattering of the graphs of the recorded parameters and the grid determines the total current flowing through the electrosensitive carrier 1 3,
