The invention relates to telegraphy and can be used in telegraph apparatus and data transmission apparatus,

The purpose of the invention is to improve the accuracy of the formation

Drawing 1 shows a structural electrical circuit of the proposed device,

The device for forming a set of code combinations contains control triggers 1, element OR 2, first 3 and second 4 elements AND, start triggers 5. and reset 6, switching unit 7, distributor 8, first 9 and second 10 keys and drive P,

The device works as follows.

When a command is received to transmit a complex set of code combinations, the triggers 1 go into the working position and at their outputs appear potentials arriving at the inputs of the OR 2 element and the corresponding inputs of the switching unit 7 and through its elements the inputs of the keys 10, the Potential from the output of the triggers 1 is also fed to the second inputs of the keys 9c

At the output of the OR 2 element, a start signal appears, which through the AND 3 element of the cerebral cortex activates the start trigger 5 (state l), the latter gives the start signal to the distributor 8 (input C) and simultaneously to the blocking circuit (not shown) TA keyboards and transmitters (not shown) with teM, so that work on the keyboard and transmission from the transmitter do not interfere with the formation of a set of coding combinations. In addition, with this signal, the flip-flop trigger 6 goes into the working position (cocked position - state O).

The clock frequency (wiring frequency) from the TA circuit is fed to the input of the distributor 8, the outputs of which (shown 20 possible:% of moves for a set of 20 characters) alternately appear potentials arriving at the first inputs of the keys 10,

If at the inputs of one of the groups, the JQ key has the same potential (for a five-element code, the group consists of five keys, for groups of the seven-element code, the group consists of seven keys)

the outputs of the keys 10 of this group, depending on how the diode grid of the switching unit 7 is programmed, a potential log appears. 1 or log. O entering the transmitter 1J of the transmitting part of the transmitter (TA). It is also possible for the five-element code to have seven keys 10, since the absence of potentials at the sixth and seventh outputs is taken as a log. 1 and the line will not be transmitted in the five-element code (when the TA scheme is operated in the five-element code).

Depending on the number of code combinations in one or another set of code combinations, the potentials from the distributor 8, appearing at the outputs (second, third, fourth and one-way) of keys 10, appear at the first inputs of keys 9 (the first output does not is specified, since usually a single code combination is transmitted from the keyboard, in the case of a network it is necessary to transmit such a combination of code coming not from the keyboard, but from some other source, you must use the first output and therefore have a diode grid for one code combination).

If there is a potential at one of the second inputs of keys 9, depending on which trigger 1 is turned on, and if there is potential at the first input of keys 9, the output of this corresponding key 9 produces a signal to form a group of code combinations that appears at the input of the element And 4 matches.

When a clock pulse appears at the second input of the I 4 element, a signal is output to the S input of the reset trigger 6, putting it into a working state (Log.1). At the output of the flip-flop 6, a reset signal appears, arriving at the R input of the distributor 8 for stopping and resetting it to its original state. This signal also translates the control and start triggers 1 and 5, respectively, to the inoperative position (initial state), the device is ready for the formation of the Spider-series of code combinations.

Upon transition of the corresponding trigger 1 to the initial state, the potential is removed from the switching unit 7, and the outputs of the keys 10 de-energize and do not affect the drive

P. Unlocks for keyboard or trinsmitter operation are also removed.

Thus, any set of code combinations containing two, three, and so on combinations can be formed.

The proposed device provides automatic input of a set (series) of code combinations, which significantly shortens the functional capabilities of the keyboard device, improves the accuracy of formation and the transfer rate of the required set of combinations.
