The device works as follows.

When the control element on the remote control 22 corresponding to the required program (marking sign) is pressed on the remote control 22 of the program block 21, the latter issues a signal to information 15 - in information output 19 - 19 of the encoder 20 in coded form.

On-board inputs 18 of the registers 17. At the same time, from the second output of the program block 21, impulse and potential formers of the former 23 are started, from which the signals go to the first control inputs of the registers 17. As a result,

35 is the writing of the mark code to registers 17.

When the controls on the console 22 are pressed, the subsequent marked characters from block 21 to registers 17 are written in the same way as the specified information required for marking. To fix the information recorded in the registers of information, the actuating element 11 is pressed through

 S electrolyte layer to the marked product 10.

Next, control element 2 is pressed and, by time relay 1, the pulse source 4 of power supply is started for a predetermined time, the phase outputs of which receive phase-shifted and time-separated voltage pulses (Fig. 3)

The voltage pulses of each phase, acting on the second control inputs of the registers 17 connected with them, open the outputs 16 of the registers 17 of the corresponding phases, in addition, the keys

12 corresponding phases. The keys 12, controlled by the registers I7 through the wires 15, connect to the actuator 11 a power source 4, the current from which creates marks on the product.

Shaper 23 works as follows.

The pulse driver creates a read pulse for writing, and in a potential driver, the modes of the shift registers are encrypted in the binary code, either forward or reverse. The delay circuit on the triggers 26 and 27 together with the generator 28 is designed to eliminate the influence of the bounce of the switchable contacts of the controls of the program block 21 and create a steep edge of the readout pulse being formed.

Shift registers 17 with switchable outputs (Fig. 4) and a snapshot at the state - 1, О and Disabled. Three-state circuits allow multiple sources of signals to be switched on for one pin. At any time, one of the registers is connected to the bus, and the rest, due to being in the disconnected state, do not affect the bus. Such registers are manufactured by industry, for example, a register of type K155IR15.

The known device having a 64-wire bus allows marking the product with an eight-digit word consisting of eight-segment letters from which all numbers and several letters can be formed.

A device with a two-phase power source allows, under the same tires and other approximately equal conditions, to obtain an alphabet consisting of 16 segment letters, from which all numbers and letters of the Russian and Latin alphabets can be formed.
