Description

one

The invention relates to the field of automation and computer technology, in particular, to devices for recording information, and can be used to register, preprocess fast processes and enter them into a digital computer, as well as to output information from digital and analog computers.

Known devices for recording information.

The known device contains an electrostatic recording field forming unit connected via a recording electrode selection unit with a control unit and a comparison unit, the inputs of which are connected to the input of the device and the threshold voltage generating unit, timing trigger and AND, OR 1 elements.

A disadvantage of the known device is the low accuracy of recording information.

The closest in technical solution is a device containing comparison blocks, the inputs of which are connected to a digital-analog converter and through amplifiers to the input of the device, and the outputs are connected to the OR element, a pulse generator connected via an AND element to the counter. -analogue converter, electrostatic recording field generating unit connected to the switching unit, recording pulse driver and keys 2.

The drawback of the device lies in its structural complexity.

The purpose of the invention is to simplify the device.

The goal is achieved by the fact that in the device one input of the switching unit is connected via the first key to the recording pulse shaper connected to the element AND, and the other input is connected to the counter via the second key, and the electrode switching unit contains a diode array, and forming an electrostatic field, the record contains successively located groups of electrodes, around each of which there are mounted plates of counter electrodes connected to the first formers, while the inputs

the odd groups of electrodes are connected to the second pulse shaper, and the inputs of the even groups to the third.

FIG. 1 shows a block diagram of the device; in fig. Figure 2 shows the constructive implementation of the electrostatic field formation unit.

The device includes amplifiers 1, comparison units 2, digital-analog converter 3, element OR 4, write pulse shaper 5, first key 6, control unit 7 containing AND 8, pulse generator 9 and counter 10, second key 11, switching unit 12, recording unit for forming electrostatic field 13, containing recording electrodes 14 and counter electrode 15.

FIG. 2 shows one embodiment of a design of block 13, including even and odd groups of electrodes 14, plates of counter electrodes 15, and shapers 16, 17, 18.

The device works as follows.

The recorded analog information signals through the input amplifiers 1 are fed to comparison blocks 2, where their amplitudes are compared with gradually increasing voltage produced in the digital-analog converter of converter 3. At the moments of equality of amplitudes, short coincidence pulses are generated through the element 4 or 4 to the driver recording element 5 pulses.

Let element 8 be open and pulse counter 10 in the zero state. The pulses from the pulse generator 9 are fed to the input of the counter 10 of the block 7. The current code value increases, as does the national output of the digital-analog converter 3. At the time this voltage coincides with one of the input signals acting on the inputs of the blocks 2, is a short pulse at its output and through the element OR 4 starts the pulse shaper of recording 5 elements of the image, the produced pulse locks the element AND 8, i.e., the state of the counter 10 stops at the previous value. Due to this state, Voltage switch 11 and block 12, made in the form of a diode array, connect the output of the high voltage switch 6 to the required electrode 14 of the block 13, while the high voltage switch 6 simultaneously provides a registration pulse to the specified electrode 14 of the block 13. After the pulse shaper Record 5 is returned to its original position, And 8 is unlocked, and the current value of the pulse counter 10 of block 7 is further changed until the next comparison of the amplitudes of the recorded signal and the signal at the output of block 3. By After the pulse counter 10 is filled, it is automatically reset with the same pulses from the generator 9. The pulse counter 10 can be reversible, so that the number of elementary points of the image can be doubled.

Block 13 works as follows. Unit 12 generates pulses that are formed in high-voltage drivers 17, 18. Pulses from the outputs of these drivers through the corresponding buses arrive at the corresponding electrodes of 14 odd-numbered groups. It should be noted that negative-polarity pulses with an amplitude of 300 V arrive at the electrodes. At the same time, pulses of positive polarity with an amplitude of 300 V are transmitted from the other group of outputs of unit 12 sequentially through corresponding high-voltage formers 16 to plates of counter-electrodes 15. Thus, with the arrival of negative pulses at the electrodes of one group per counter electrode, positive pulses also arrive. However, despite the fact that negative polarity pulses arrive in succession at the electrodes of odd groups, only the electrodes of the group whose positive electrodes are pulsed are recorded. Thus, the possibility of a false record is eliminated, since the charged electrode is located through a group of relatively charged electrodes of another odd group. As soon as the electrodes of the group will receive a predetermined number of pulses, the block 12 generates a signal according to which

5, pulses are formed, which successively through the corresponding high-voltage driver 18 are fed to the corresponding electrodes of even groups. Simultaneously with another group of outputs, a sequence of positive-polarity pulses passes through shaper 16. Recording occurs only from a group of electrodes, on the plates of the counter-electrode of which pulses of positive polarity are applied.

The introduction of new constructive relations

allowed to significantly simplify the device.
