When the reticle 19 is moved to the first point of reference by the Stalin cables 23, the linear movement is converted into rotational motion of the reels 20 with the disks 21, whose slots alternately intersect the optical channels of the photo-reading elements 25, at the outputs of which a sequence of mutually shifted pulses appear.

This sequence of pulses is fed to the input of the corresponding ampli fi ers 4 and 5, where it is converted into a sequence of rectangular pulses fed to the inputs of registers 6 with a unitary output, in which the input sequence is converted into a unitary code, the state of which is determined by the code input sequence. The change in the logical state of the outputs of registers 6 occurs from the low bit to the highest when the reticle is moved directly and from the high to the low when reversing the reticle 19. The outputs of the registers b at any time are decoded by the corresponding decoders 7 and 8, the outputs of which are are the pulses corresponding to the forward or reverse movement of the viewfinder 19. These pulses arrive at the summing or subtracting inputs of the reversible counters 9. The number of pulses contained, in the counters, is strictly proportional to linear linear displacement of the viewer along the coordinate axis.

After leading the viewfinder 19 to the first point of the graphic document, the button for entering 2 coordinates is pressed, with which the signal is supplied D block 10 - the perforator. In the initial state, the trigger 29 is in the reset state, which prohibits the operation of the clock generator 27. The counter 28 also ng-goes in the reset (zero) state. When you click on the button: Enter 33, the entry trigger 29 goes into one state.

At the outputs of the imaging unit for entering information 31 through X and Y, an impulse is generated for entering information into the registers.

a block of counters 28, simultaneously starts to generate a generator 27. On the front of the pulses at the output of the clock generator 27, the key block is triggered, and the address of the digits changes simultaneously. After eight cycles, the device will return to its original state.

The information entry generator 30 (31) generates a transfer pulse, which enters the blocks of counters 9. The first pulse from the output of the generator 27 goes to a digit counter 28, from the output of which the number of digits is fed to the address input of the multiplexer 12, through which the digits of the digits switch. The bits of the first digit through multiplexers 12 commute to the inputs of the decoder 13.

At the input of the decoder 13 is a post, a Z-code combination of digits from the output of multiplexers 12, according to which at one of the outputs, which corresponds to the combination at the input, control signals appear.

Decoder 13 by impulse v. y coming from the output of the generator 27, turns on the relay 35. On the same impulse, the code combination is changed and the further process of working is similar to the above.
