The invention relates to automation and computational engineering 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.

The drawing shows a diagram of the proposed device.

The device contains the first generator 1 of pulses, the control element 2, the first group of elements ZI-NOT 3, counters 4, decoders 5, indicators 6, the second group of elements 7, the first 8 and the second 9 keyboard elements, the distributor 10 pulses, the second generator 11 pulses , frequency divider 12, BANKS 13, contact pad 14 of the first touch key element, reversible counter 15, decoder 16, contact pad 17 of the second touch key element, inverters 18, elements 2И-НЕ 19, triggers 20.

The purpose, construction and function of the pulse generator 1, the control element 2, the decoder 5, the indicators 6, the touch key elements 8 and 9, the second pulse generator 11 are similar to those of the known device.

Each of the counters 4 is intended to sequentially form a specific set of code signals in the required order when the pulses arrive at the input. Counters 4 are counters with an arbitrary coefficient and order of counting. The construction of each counter 4 depends on the number of symbols that can be dialed by the operator on the indicator 6 associated with this counter 4. The construction of such counters is well known. I. The distributor 10 is designed to generate a logical 1 signal at a certain output, which is connected by connecting a specific indicator for typing or editing information. Distributor. 10 is built on the basis of a reversible counter 15 with two counting inputs and a decoder 16. Input C1 counter

15 is summing and input C2 is subtracting.

The device works as follows.

The first generator of 1 pulses generates rectangular pulses with a frequency of 3-5 Hz, which are fed to the first input of the ZY-NOT elements of group 3. When the pad 14 of the touch key element 8 is touched, a logical signal 1 is generated at its output. Simultaneously with the contact site 14 is carried out impact on the mechanical

5, a control element 2 associated with the platform 14. In this case, the contact platform 14 is executed on the part of the control element 2 to which the operator’s pressing force is directly applied. The magnitude of the effect on the control element 2 determines the frequency of the pulses of the first generator 1 of the pulses. The signal of logical 1 from the output of the touch keypad element 8 of the set is fed to the inputs of the ZI-NOT elements of group 3. At the same time, the pulses from the first generator 1 pass to the output of only one element of group 3, to which the signal of logical 1 is received from the distributor 10. Pulses from the output element ZI-NOT of group 3 is fed to the input of the corresponding counter 4. The code signal generated by the counter 4 is determined by the number of pulses arriving at its input, as well as its construction. The code signal from the output of the corresponding counter 4 is fed to the input of the corresponding decoder 5. The decoder 5 converts the code of the counter 4 into the code of the indicator segments 6. Indicator 6 displays the symbol corresponding to the code.

Thus, when the contact pad 14 is touched on one of the indicators 6, determined by the state of the distributor 10, a certain sequence is displayed.

0 characters.

The frequency of symbol changes depends on the magnitude of the effect on the control element 2.

Termination of contact

5 pads 14 leads to the disappearance of the logical 1 signal at the output of the touch key element 8 and at the second input of the ZI-NO elements of the group

3. At the same time, the pulses from the first generator 1 cease to pass to the output of the elements of the 3-NO group 3. 3. Thus, fixation of the required symbol in the counter 4 and the corresponding indicator 6 is ensured. In addition, the negative signal front, formed when the contact pad 14 stops contacting, is fed to the summing input C1 reversely of the counter 15 of the distributor 10 and increases its value by one. In this case, a logical 1 signal is generated at the next output of the decoder 16 of the distributor 10. When the contact pad 14 is tapped, a sequence of characters is generated on the next indicator 6. Thus, a consistent set of necessary characters occurs on all indicators 6.

Using the key element, the operator can edit the already fully typed message or return to any in a consecutive row of indicators 6 and, starting with it, continue typing the message. When the contact pad 17 of the keyboard touch element 9 is touched, the logical 1 signal arrives at the subtracting input C2 of the reversing counter 15 of the distributor 10 and reduces its value by one. In this case, the form 2111144

The logical 1 signal at the previous output of the decoder 16 of the distributor 10 is simulated. Cascade the required number of times of the contact pad 17, the operator can return for editing or further dialing to any indicator 6. At the same time, each touch of the pad 17 does not affect the coding signal , formed by the counter- | mi 4. In addition, the signal of logical 1 keyboard sensor elements 9 when it is touched is fed to the first input of the elements ZI-NOT group 7, on

(5, the third input of which is fed with pulses with a frequency of 5-20 Hz from the output of frequency divider 12. When this is, the output of the ZI-NO element of group 7, to the input of which the signal is

20 1 from the output of the distributor 10, the pulses from the frequency divider 12, which are post-fed to the input of the corresponding BANES 13, pass through, are connected with the operating mode

25th indicator with them (set the blinking mode with a frequency of 5-20 Hz).

Thus, the operator, by contacting pad 17, observes which indicator 6 he has returned to for editing or further typing the message.

The second generator 11 is designed to operate the sensor elements 8 and 9.
