The invention relates to automation and computing and can be used in devices for entering information into a computer, as well as in other electronic devices having a keyboard for manual typing and data entry.

The aim of the invention is to increase the speed of the device.

FIG. 1 shows a block diagram of the device; in fig. 2 - an example of a specific implementation of the device; in fig. 3 - functional diagram of the parameter length setting block; in fig. 4 - the number generator is functional.

The device for entering information (Fig. 1.2) contains the first generator

transition of the counter to the next previous state. In this case, under the action of the code combination coming from the counter and block 5 to the inputs of the Ml matrix, signal 1 appears each time at a certain output of the matrix M2.

The sequence of signals at the outputs of the matrix M2 under the action of code combinations from block 5 and counter 4 is laid during the synthesis of matrices Ml and M2, taking into account the positional structure and the number of characters of the parameter to be dialed.

Each of the 10 number generators is designed to sequentially form in a necessary order a certain set of code signals.

The parameter length setting block is designed to sequentially form a signal 1 at the outputs 1 ... ... m + 1 in accordance with the positional structure and the length of the parameter to be dialed.

The parameter length setting unit 4 (FN.Z) is a software automaton and is implemented on the basis of a programmable logic matrix (MRP) consisting of matrices Ml (forming q different conjunctions) and M2 (realizing various disjunctions).

In the initial state, at the outputs of the counter of block 4, a zero combination of signals is formed, which

The 10-number generator (FIG. 4) is a programmable automaton (PA} implemented on the basis of a PLA with a memory consisting of HI matrices (forming q different conjunctions) and M2 (which implements r + t different disjunctions) and contains r - bit register in the feedback circuit.

Under the action of a combination of S signals from the output of the data type setting unit and a combination of signals received from the output of the RG register through the feedback circuit, the user agent generates a combination of t signals corresponding to the character code and the input to the decoder 11, and also a combination of r signals arriving at the input of the RG register and corresponding to its next state, In the initial state under the action of the zero combination of signals c; the RG register, regardless of the value of the code coming from counter 16, the software automaton at the outputs l, .. t forms a zero combination of signals, and at the outputs G.

consequently, the combination of signals at the input of the automaton is changed. Under its action, the user agent at the output generates the code of the next character and the new code of co31

This is neither the RG register. Synchronously with the arrival of pulses from the output of the element AND-IE 8, the PA generates a sequence of characters, the number and set of values of which are determined by the structure of the PA and the code received from the counter 16.

After the last character is generated, the code corresponding to the original is written to the RG register, and the user agent starts repeating the sequence of character codes.

The device works as follows.

The first pulse generator 1 generates rectangular pulses with a frequency of 3-5 Hz, which are fed to the input of the first elements AND – NE 8. When the pad pad 17 touches the dial 2 key, a signal 1 is generated at its output.

Simultaneously with the touch of the contact pad 17, the control element 22 is mechanically connected to the pad 17. In this case, the contact pad I7 is performed on that part of the control member 22 to which the operator’s pressing force is directly applied. The magnitude of the effect on the control element 22 determines the frequency of the pulses of the first pulse generator 1. The signal 1 from the output of key 2 of the set goes to the inputs of the first AND-N units 8. In this case, the pulses from the first generator 1 of the pulses go to the output of only one of the first elements NID 8, to which the signal 1 is sent from unit 4 of the parameter length setting The pulses from the output of the element AND-NOT 8 are fed to the input of the counter 16 of block 5 or one of the number generators of 10 blocks 6.

The code signal generated by the counter 16 is determined by the number of pulses trapped at its input, as well as its construction. The code signal generated by the generator of 10 numbers is determined by the number of pulses arriving at its input, by the code signal coming from counter 16 as well as its construction. The code signal from the output of the counter 16 or the generator of 10 numbers is fed to the input of the corresponding decoder 11. The decoder 11 converts the counter code 1 6 into the code of indicator segments 13.

The indicator 13 displays the symbol corresponding to the code.

Thus, when Touching the pad 17, one of the indicators 13, determined by the state of the parameter length setting block 4, displays a certain sequence of characters,

The frequency of symbol changes depends on the magnitude of the effect on the control element 22.

Termination of contact pad 17 leads to the disappearance of

signal 1 at the output of key 2 of the set and, accordingly, at the input of the first elements AND-NOT 8. At the same time, the pulses from the first generator 1 of the pulses no longer pass to the output of the elements AND-NE 8. Thus, fixation is provided in the counter 16 of block 5 or the generator 10 numbers of block 6 and the corresponding indicator 13 of the required character. In addition, the negative signal front, formed when the contact pad 17 stops contacting, is fed to the summing input C1 of the counter of block 4 and increases its value by one.

Signal 1 is then generated at the next output of block 4. When the contact pad 17 is subsequently touched, a sequence of symbols is generated on the next indicator 13, as described above. Thus there is a consistent set of required symbols on all indicators 13.

The first indicator displays

the parameter symbol (message type symbol) determined by the state of the counter 16. On each of the subsequent indicators when the parameter characteristics are set (message content)

only the required set of characters is displayed, which is determined by the construction of the character generator and the code received from counter 16, i.e. character set depends

on the type of message typed and familiarity in the message-.

The code combination (parameter type), recorded in the counter 16, entering the inputs of block 4, determines the number of characters contained in the parameter characteristic and its positional structure. In this case, the sequence of forming signals at the outputs of block 4, and hence the sequence of filling the message positions on the respective indicators 13, is determined by the type of the message (parameter) being dialed.

After dialing the last character, the signal I is transferred to the output m of block 4, allowing the formation of an input signal. When the contact pad 17 is subsequently touched by element I7, an information input signal 5 is generated which is permissive for reading information. When releasing the contact pad 17 at the output of ha + block 4, a signal 1 is generated, which is fed to the R- input of the counter and resets it to the zero state. At the first output of block 4, a signal 1 is formed, which resets all the registers RG of the generators 10 numbers of blocks 6, and all indicators 13 with the entered parameter values are extinguished, which is a sign of the current input. The signal from the first output of the block 4 setting the parameter length also permits the passage into

The device can be used in a subminiature calculator.

The counter 16 pulses from the output of the element IS-NE 8 with the contact of the contact area of 30 input devices, in special slots 1 7, thereby allowing the choice of the control and processing complexes of the next parameter, as described above.

When the contact touches the 40 H illumination, the work in the I8 pad of the edit key 3, the signal 1 is fed to the read input C2 of the reversible counter of block 4 and decreases its value by one. In this case, a signal 45 1 is generated at the previous output of block 4. Kasa the required number of times of pad 18, the operator can return for editing or
