The user of the information help system calls documents from the filing cabinet to the display device, using the function keys on the control panel. Editing of documents is done by users who have provided sufficient credentials when logging in to the system using the standard keyboard 65 (FIG. -2).

For most information and reference systems, the number of xparif documents in them is much larger than the number of their forms. Therefore, to save the number of storage units of the device’s memory used for storing documents, the documents stored in the storage units have a structure (FIG. 4), where the first K1 bits are the contents of the document, the second K t. Bits are the address the template (the template is understood as the unchangeable part of the document, the headings of the tables, headings, dividing lines, auxiliary information, etc., FIG. 6), the third

K ,, bits contain the address of the previous document, the fourth K4 bits - the address of the next document.

The card index is thus broken up into several ring lists, the number of which is equal to the number of subject areas (Fig. 5).

The sets of documents in each of the subject areas are recorded in the memory block f, the set of templates of the documents used in the memory block 2 (Fig. 1, the writing circuit in the memory blocks are not shown). The addresses of the template, the previous and the next documents are recorded in the corresponding fields of the documents (Fig. 4), the addresses of the representatives of each subject area (the representative can be any of the documents).

The target list corresponding to the subject area) is recorded in registers 3 - and 4 using write circuits connecting the information inputs of the device and the synchronization input 55 of the device with registers 3 and 4.

The device works as follows.

If it is necessary to work with the informational reference system, the user presses the key of driver 49 on the control panel. At that, the stop 61 closes the current flow circuit of the blocking generator 63 and a pulse U iwcK appears on the output 64 of the driver (Fig. 3a).

The impulse U pugzh arrives at the inputs of the elements AND blocks 16 and 17 of the pass thus through these elements and elements OR blocks 20 and 21 of the values stored in registers 3 and 4 (i.e. addresses of documents - representatives of each of the subject areas) . These values are recorded in registers 5 and 6 with the help of pulse U "Usk, which passed through the elements OR 29 and 30 to the synchronization inputs of registers 5 and 6. Denote by t ZepG.0 the load time of addresses of documents - representatives from registers 3 and 4 to registers 5 and 6, and after t T is the response time of each of the triggers 11-14.

The impulse U start is delayed on delay element 45 at time t Eagr, 0- tT, hits the single input of trigger 13, previously in the zero state, and exposes a high potential value at its output (Fig. 36), after which makes it possible to receive control pulses from drivers 47 and 48, i.e. the passage of pulses from the outputs of the formers 47 and 48 through the elements of AND 22 and 23 is permitted.

For definiteness, the former 47 is thought to work.

The impulse U, from the output of the imager 47 (Fig. 3g) passes through the element 22 and 22, at the other inputs of which the high potential values are exited from the output of the trigger 13 and from the inverse output of the one-shot 15, and through the element OR 31 to the inputs of the elements And block 18, resulting in the address of the document of the representative of the first subject area from the output of the register 5

51

It goes through elements AND 18 and elements OR 28 to the address input of memory block 1. Passing through the OR element 36, the pulse U4 resets the triggers 11 and 12 to the zero state, and falls on their zero inputs. The impulse U., Delayed by the delay element 38 at the time t T and arriving at the single input of the trigger 11, exposes at the output of the trigger 11 a high potential value (Fig. 3). After the passage of the element OR 36, the pulse U reaches the input of the one-shot 15, thus the low value of the potential at the time t, iarf, at its inverse output (fig.Sv). During the time t ar, the reception of new control pulses from the outputs of the formers 47, 48, 51 and 52 is impossible.

After passing the elements AND 22 and OR 36, the pulse U is delayed on the delay element 40 by time t31 (equal to the response time of elements whose operation is triggered by the pulse U, and described) and forms at the output of the delay element 40 a pulse U Бп, (FIG. 3k) which enters the synchronization input of memory 1, the address input of which contains the address of the document representing the first subject area, resulting in a time t Zi equal to the reading time of the document from memory 1, an information word representing The entrant, representative of the first subject domain, is written to register 7 with the help of a pulse delayed on delay element 41.

The first K., bits from the output of the register 7 are fed to the information output 56 of the device, the second Kg of the bits from the output of the register 7 - to the address input of the memory block 2, the third Ke of the bits from the output of the register 7 - to the information input of the register 10, the fourth To 4 bits from the output of the register 7 - to the information input of the register 9.

The impulse U 6 (M, delayed by elements 41 and 42 for the time t Ja t em + tj 7, where t 1 1- the delay time on the element 42, equal to the recording time in register 7, forms and at the output of the delay element 42 U 6P-g (Fig.Zl).

10 and memory block 2, writes the address of the next document into register 9, and registers 10 with the address of the previous document, and reads from the memory block 2 5 an information word representing a pattern read from document memory 1.

The impulse Ugn delayed by the delay element 43 at time t33 equal to the pattern reading time from memory block 2 writes the information word from the output of the second memory block, which is the pattern of the document read from memory 1, to the register 8 on the sync input of this register. Delayed on delay elements 43 and 44 at time t3 33 + t 3 4,

where t C 4 - the delay time on the element 44, equal to the recording time in the register 8, the pulse U Бп-г forms at the output of the delay element 44 the pulse U in “(FIG. 3m).

25 Thus, as a result of receiving a pulse U-, received from the output of the imaging unit 47, an information word is displayed at the information output 56 of the device, which represents the contents of the document, at the information output 57 of the device there is an information word representing the document template and on the synchronizing output 58 of the device, a pulse UBK is formed, which is used as an interrupt signal of the computing complex, according to which the latter initiates the processes of reading information from outputs 57 and 58; combining the template and document contents into a single document and displaying the document on the display screen.

The time t3ar., Is chosen so that the following relationship holds:

t Sarpi t 3 1 + t E.g + t uh,

therefore, blocking the reception of new control pulses is released after the formation of a U6K pulse. After this point, it is possible to receive new pulses from the outputs of the formers 47, 48, 51 and 52.

Receive pulses from the outputs of the formers 51 and 52, which correspond to

The call buttons for the next and previous documents become possible only after the high potential at the output of trigger 14 appears, which is caused by the arrival at the single input of trigger 14 from the output of the OR 36 element of the first pulse generated at the outputs of the formers 47 and 48 (FIG. Zo).

It is believed that the shaper 51 o triggered. A pulse U formed at its output, Sfg.C3), passed through elements AND 34, OR 37 and 36 to the input of the one-shot 15, exposes a low potential value at its inverse output, i.e. Blocks the reception of new control pulses at the time of Tsigr., (Figure 3b). The impulses that hit the inputs of elements AND of group 26 allow passage through them of the elements OR of group 33 and the elements of OR of groups 20 and 21 of the address of the next document of the first subject area to the information inputs of registers 5 and 6 "This address is recorded in the register 5 due to the fact that only the trigger 11 is in the single state, which permits the passage of the register 5 to the synchronizing input through the AND 24 and OR 29 elements of the pulse resulting from the pulse passing and through the AND 34 and OR 37 elements. - hell res the next document of the first subject area. Further processes leading to the output of the contents of the new document and its template to the information outputs 56 and 57 of the device and the generation of an interrupt signal of the computing complex at the synchronizing output 58 of the device occur similarly.

In the case of the arrival of the control pulse Ua (Fig.Sv) from the output of the imaging unit 48, all the triggers 11 and 12 are reset to the zero state by the pulse U1 that passed through the elements AND 23 and OR 36 to the zero inputs of the triggers 11 and 12. Pulse by delaying the delay element 39, at time tT, the trigger 12 is set to one (Fig.Zh), which corresponds to the choice of a new subject area.

The reception of the pulse Ui results in the appearance of the content of the document of the representative of the new subject area at the information output 56 of the device, the template of this document at the information output 57 of the device, and

The characteristics of the pulse UBK, similar to that described.

The call of other documents of the new domain is also carried out using the keys of the formers 51 and 52.

For example, if the shaper 52, which corresponds to pressing the previous document key, triggered, the impulse U from the shaper 52 output (Fig.Zi), passed through the AND 35, OR 37 and 36 elements to the input of the one-shot 15, exposes a low on its inverse output potential value, i.e. blocks the reception of new pulses at time t EA (1 ,, (fig.Zv). Pulse U prev, hit the inputs of elements AND of group 26, allows passage through these elements AND, elements OR of group 33, elements OR of groups 20 and 21 of the address of the previous document of the first subject area to the information inputs of registers 5 and 6. This address is recorded in register 6 due to the fact that only trigger 12 is in one state, which allows passage to the synchronizing input of register 6 through AND 25 and OR 30 pulses, the resultant momentum And passed through the elements of AND 35 and OR 37. The address of the previous document of the first subject area is recorded in register 6. Further processes leading to outputting the contents of the new document and its template to the information outputs 56 and 57 of the device and generating an interrupt signal of the computer complex at the synchronization output 58 devices occur as described.

The operation of the device ends with the arrival of a pulse UCTOP (FIG. 3N) from the output of the imaging unit 50. The impulse UThe stop arrives at the zero inputs of the flip-flops 13 and 14, which leads to the appearance of low potential values at the outputs of the flip-flops 13 and 14 (FIG. 13). . As a result, it becomes impossible to receive pulses from the outputs of drivers 47, 48, 51 and 52.
