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 purpose of the invention is to increase the speed of the device by selecting the data presented to the operator.

FIG. 1 shows a block diagram of the proposed device; in fig. 2 is an example of its concrete implementation. organizations; in fig. 3 - a functional number generator.

The device (Figures 1 and 2) contains the first generator of 1 pulses, the key 2 sets, the edit key 3, the distributor of 4 pulses, the data type setting unit 5, the blocks 6.1 - 6.N data generation, element 7, the first and the second elements are NAND 8 and 9, respectively, 10 numbers generator, first 1I decoder, BANKS 12 elements, indicator 13, second pulse generator 14, frequency divider 15, GB counter, reversible counter 17, second decoder 18, pads 19 and 20 keys 2 and 3, respectively, the element is NOT 21, the third element is P1-HE 22, trigger 23, control gash, ile ele UNT 24,

Each of the 10 number generators is designed to sequentially form in a necessary order a certain set of code signals depending on the code received from the counter 16 of block 5 when pulses from the first element AND-HE 8, the number generator 10 are received (FIG. 3). It is a programmed automaton (PA) implemented on the basis of a programmable logic matrix (PN) with a memory consisting of matrices Ml (forming q different conjunctions) and M2 (realizing r + t different disjunctions) and containing g-bit single register RG in price pi feedback.

Under the action of a combination of s signals that are outputted from the output of the counter 16 of block 5, and a combination of r signals from the output of the RG register on the PA feedback circuit, the output generates a combination of t signals corresponding to the character code and fed to the input of the decoder 11 , as well as a combination of g signals, pos323072

stupid to the input of the register RG and corresponding to its next state. In the initial state, under the action of the zero combination of signals from the RG register, regardless of the value of the code coming from counter 16, the automatic program at the outputs l ... t forms a zero combination of signals, and

10 at the outputs 1 ... g is a combination of signals corresponding to the following state of the RG register (other than zero).

When a pulse arrives at the counting input of the D-flip-flops of the RG register, their state changes and, therefore, the combination of signals at the input of the automaton also changes. Under its action, the PA generates a code at the output.

The next 20 characters and the new RG register status code. Synchronously with the arrival of pulses from the output of the element AND-NOT In PA forms a sequence of characters, the number and set

25 values of which are determined by the construction of the user agent and the code received from the counter 16.

After generating the last character in the RG register, the code is written,

30 corresponding to the original, and the user agent starts repeating a sequence of codes, a symbol.

The device works as follows.

25 The first generator of 1 pulses generates rectangular pulses with a frequency of 3-5 Hz, which are fed to the input of the first AND – NE 8 elements. When the contact area 19 is located on the keyboard 2 and 2 sets, a logical 1 signal is generated at its output.

 Simultaneously with the touch of the contact pad 19, the control element 24 mechanically connected with the pad 19 is actuated. At the same time, the pad 19 is executed on the one. part of the control element 24, to which a direct pressing force of the operator is directly applied. The magnitude of the effect on the control element 24 determines the pulse frequency of the first pulse generator 1. The signal of logical 1 with the output of key 2 of the set enters the

gg the inputs of the first elements AND-NOT 8, In this case, the pulses from the first generator 1 of the pulses pass to the output of only one of the first elements AND-NOT 8, to which 4 pulses from the distributor

the signal is a logical one. 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 generators 0 the number of blocks 6.

The code signal generated by the counter 16 is determined by the number of pulses arriving 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 caught at its input, by the code signal received from counter 16, as well as by its construction. Kodo-15 characters depend on the type of dialed signal from the output of counter 16 or the generator of 10 numbers is fed to the input of the corresponding decoder 1. The decoder 11 converts the counter code 16 into the code of the indicator segments 13. 20 The latter displays the symbol corresponding to the code.

Thus, when the pad 19 is touched, a certain sequence of characters is displayed on one of the indicators 13, which is determined by the state of the distributor 4 pulses.

The frequency of symbol changes depends on the magnitude of the effect on the control element 24,

The termination of the contact pad 19 leads to the disappearance of the signal logical 1 at the output

Go message and familiarity in the message.

After the last character of the dialed parameter is displayed on the indicator 13, when the pad 19 of the dial key 2 is released, a signal appears at the output m of the distributor 4 pulses. The next time you touch the pad, 19 element 25 and 7, an information input signal is generated that is permissive for reading information. On the falling edge of the signal from the output of key 2 of the set, the distributor of 4 pulses generates a signal at the first output, which resets all RG generators 10 numbers of blocks 6 and all indicators 30

the keys 2 of the set, and, accordingly, rya 13 with typed para values 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 performed in the counter 16 of the block 5 or the generator 10 block numbers 6 and the corresponding indicator 13 of the required character. In addition, the negative edge of the signal, formed when the contact pad 19 stops contacting, is fed to the inverse summing input C1 of the reversible counter 17 of the distributor 4 pulses and increases its value by one. In this case, a logical 1 signal is formed at the next output of the second decoder 18 of the distributor 4 pulses. When the contact pad 19 is subsequently touched, a sequence of symbols is generated on the next indicator 13 as described above. Thus, sequential

The meter goes out, which is a sign of input status. The signal from the first output of the distributor 4 pulses also permits the passage of 16 pulses into the counter from the output of the NANDI element 8 when the contact pad 19 is touched, thereby allowing the selection of the next parameter, as described above.

Using the edit key 5, the operator. Can edit an already fully typed message, or return to any, in a consecutive row, indicator 13 and, starting with it, continue typing the message. When the editing pad 20 of the key 3 is edited, the signal of logic 1 is fed to the subtracting input C2 of the reversible counter 17 of the distributor 4 pulses and decreases its value by one. When the signal is generated, the logical 1

On the first indicator, display the parameter symbol (a symbol of the type of admission), determined by the state of the counter 16. On each of the subsequent indicators, when a set of parameters of the parameter (message content) is displayed, only the necessary character set, which is determined by the construction of the symbol generator and the code, is displayed. coming from counter 16, i.e. set of displayed

characters depends on the type of

Go message and familiarity in the message.

After the last character of the dialed parameter is displayed on the indicator 13, when the pad 19 of the dial key 2 is released, a signal appears at the output m of the distributor 4 pulses. The next time you touch the pad, 19 with the element AND 7, an information input signal is generated, which is permitted to read the information. On the falling edge of the signal from the output of key 2 of the set, the distributor of 4 pulses generates a signal at the first output, which resets all the registers of the RG generators to 10 blocks 6, and all indicators

The meter goes out, which is a sign of input status. The signal from the first output of the distributor 4 pulses also permits the passage of 16 pulses into the counter from the output of the NAND element 8 when the contact pad 19 is touched, thereby allowing the selection of the next parameter, as described above.

Using the edit key 5, the operator. Can edit the already fully typed message, or return to any indicator 13 in a sequential row and, starting with it, continue typing the message. When the contact pad 20 is edited to the key 3 of the editing signal logs. 1 is fed to the subtracting input C2 of the reversing counter 17 of the distributor 4 pulses and reduces its value by one. When the signal is generated, a logical 1 signal is generated.

the previous output of the decoder 18 distributor 4 pulses. If necessary, the contact number 20 of the pad 20 can be returned by the operator for editing or further dialing to any indicator. Moreover, each touch of the pad 20 does not affect the code signal generated by the counter 16 or the generator of 10 numbers. In addition, the signal of the logical 1 key 3 editing, when touched, enters the first input of the elements AND-HE 9, to the input of which pulses with a frequency of 5-20 Hz are output from the output of the frequency divider 15. At the same time, the output of the element IS-HE 9, to the input of which a logical 1 signal is output from the output of the distributor 4 pulses, passes pulses of the frequency divider 15, which, arriving at the input of the corresponding BAN 12 elements, control the operating mode of the indicator connected to them ( set the mode of a mih-a with a frequency of 5-20 Hz),

Thus, the operator, when touching the pad 20, observes to which indicator 13 he will return for editing or further typing the message.

The proposed device, in comparison with the known, allows to significantly increase the speed of information input, since when typing and editing the typed information on each specific indicator only a certain necessary set of characters is displayed. The set of these symbols depends not only on the familiarity in the message, but also on the type of the message (parameter) being dialed, which is displayed on the first indicator. The construction of the 10 numbers as many as up to the generator takes into account the nomenclature of symbols that are displayed on the associated indicator, and each generator has a connection with counter 16, the state of which determines the type of message to be dialed (parameter)

Generation of only iia6opa characters at each familiarity not only increases the speed of typing, but also reduces the likelihood of erroneous information input, which reduces the number of character sets and ultimately increases the speed of information input, facilitates the work and training of the operator.

The device can be used in subminiature computing input devices, in special complexes of control and information processing, in which messages with a hard order are used, the character set on each familiarity is limited and has a strong dependence on the typed message (parameter).
