CONSTITUTION:A multi-deck 1 and a file controller 2, and plural terminals T1, T2,... are connected through a bus network 3, and optical disks TDO1-TOD3 which have been provided on each terminal file information which has been sent from the multi-deck 1 side. Retrieval of information required is executed from each terminal, respectively, and in accordance with it, in the multi-deck 1, the disk is switched to an optical disk in which requested information has been stored. When the terminal T1, the terminal T2, and the terminal T3 request information A, information B, and information C, respectively, within some time, the multi-deck 1 side switches successively the disk to the optical disk in which each information has been stored, retrieves the requested information and outputs it to the corresponding terminal.

Description

[Detailed description of the invention] [Industrial use portion 1f] This invention is a document stored on an optical disc.

It relates to a method for appropriately searching and recording drawings, patent information, etc. on multiple terminals.

[Conventional technology]

2. Description of the Related Art In recent years, optical discs have been used to store various materials, and various information stored on optical discs has been searched for using one or more terminals.

[Problems solved by the invention, J: 17] When there is one search means for one optical disk deck, there is no need for people to take time to search for information because there is no other search means. However, when a plurality of information retrieval means are connected to one optical disc or f-sk deck, while one retrieval means is searching for information, other retrieval means cannot be used to search for information.

That is, when multiple types of information are stored on one optical disc, for example, it is not possible to search for another piece of information while searching for one piece of information.

It is not possible to search for another piece of information until the search for one piece of information is completed.

This also applies when searching for various information while changing a plurality of optical discs using a multi-deck.

In such cases, a particular problem arises when there are a large number of optical discs and possibly many terminals, and it is difficult to search for information stored on different optical discs from each terminal. This means that you will not be able to search for information.

This invention was made to improve these problems, and is suitable for optical discs that store one optical disc, as well as multi-optical discs that store multiple optical discs. This system automatically processes information searches from a plurality of connected terminals in the order of requests, outputs the information requested by each terminal, and records the information searched on the terminal side.

[Means for solving problems]

According to the present invention, information is recorded from a plurality of terminals, and a means is provided for automatically outputting various types of information in the order of requests, and an optical disc is also provided on the terminal side for searching. Moreover, the information sent can be filed and used according to the time schedule of the terminal side.

[Effect]

Ranking and storing information retrieval 1- from multiple terminals 17. The information requested during the time period when the operator is away from the terminal is filed in the inspection disk in the order of the requests. l- Sea urchin.

〔Example〕

FIG. 1 shows an example of application of the present invention.

For convenience, several dozen optical discs are stored here.

Although we have taken as an example a multi-deck that switches to a requested optical disc using an auto-change mechanism and retrieves information from that optical disc, it goes without saying that a deck containing a single optical disc may also be used.

In FIG. 1, 01) I to ODo are a plurality of optical disks on which information is recorded, and (1) is a multi-deck that accommodates a plurality of optical disks, and is equipped with an auto-change mechanism. +21 is a file controller that controls the multi-deck (1).

(3) is a bus network, which is formed by a coaxial bus or an optical fiber. The multi-deck (1) and file controller (2) are connected to the plurality of terminals T,, T, through this bus network (3).
.

T8. are connected. TI)O, -TOD3 are optical discs provided in each terminal and file information sent from the multi-decoder':)1γ% side. N01N
,,N2. N, - is a network interface adapter.

In such a configuration, the required information is searched from each terminal, and the multi-deck (7) is searched accordingly.
In step 1), the optical disc is switched to the one on which the requested information is stored.

zunao) also, within a certain time, terminal T receives information A,
When terminal T2 requests information B and terminal T3 requests information C, the multi-deck (1) side sequentially switches to the optical discs storing each information, searches for the requested information, and outputs it to the corresponding terminal. .

However, what if information A is patent information and the number of patent publications is tens to hundreds of pages? f, terminal T
If you try to print out the printout on the T1 side, it will take a considerable amount of time, and the T1 side will have to wait until the printout on the T1 side is finished, and during that waiting time, the operator will It's a waste of time to go for it.

- In this invention, the file controller (2) has a device 17 as shown in FIG. 2.

Figure 2 shows the features of this invention.
) is a file controller that is a feature of the present invention, and (4) is a file controller that is a feature of the present invention. The control circuit (5) connected to T is a shifter circuit that plays an important role in this invention. The signal that is input first is processed preferentially.

The second signal is processed next, and then the third signal is processed further.

Such a circuit is referred to in some patent applications as a device for storing (7) retrieving signals in the order in which they occur;
There are various circuit configurations, but here we will take as an example the one shown in FIG.

For convenience, some symbols have been changed and some parts have been expressed differently. ) This will be explained in relation to the configuration shown in FIG.

In FIG. 2(A), M1 to M are not shown in FIG. 2(B), but are a memory circuit that combines NOR elements A and B, and 2M1 to M3 are the first series, 2M4 to M6 are the second series, and M7 to M6 are the second series. M, constitutes the third series. One N that makes up the memory circuit
The OR element 8 has as many reset terminals R1 to R3 as the number of series.
The other NOR element A has a set input terminal Sin.

ES1 to ES3 are multi-deck (1) in order to stop the transmission signal when the operations of the first series, second series, and third series are completed (that is, when the information of each series is output from the optical disk). A signal input from the first
A signal ES is connected to the terminal R3 of the series memory circuit N M 3.
A signal ES2 is applied to the terminal R2 of the second series memory circuit M6.
The terminal R3 of the third series memory circuit M is connected to the signal ES.
3 is input.

To be more specific, if a signal is input from the control circuit (4) to the set input terminal of the first stage memory circuit M of the first series, the signal is transmitted from the output terminal of the memory circuit M1 to the next stage. It is transmitted to the set input terminal of the memory circuit M2 in the memory circuit M2, and to the set input terminal of the memory circuit M3 in the final stage, and is input to the multi-deck (1) from the output terminal of this circuit M3. However, this signal transmission is given to other systems, but priority transmission is always performed in relation to the order of arrival of the signals.

That is, one of the reset input terminals of the circuit M1 described in -1- is connected to the output of the input circuit M2 at the next stage, and the remaining two set input terminals are connected to the same level (memory circuit M of a certain other series, etc.).
The output of M7 is added as a reset input, and the - reset terminal of the second series memory circuit M4 is connected to the next stage memory circuit M.
output, and the remaining two reset terminals are connected to other series of memory circuits M1. The output of M is added as a reset input, the - reset terminal of the third series memory circuit M7 receives the output of the next stage memory circuit M8, and the remaining two reset terminals receive memories of other series at the same level. Circuit M□2
The output of M4 is added to the reset input at 17. 1st. Second. and a storage circuit M2 located in the middle of the third series. M, , M8 are also memory circuits M, , M4 . Connections similar to M7 are made.

The first, second, and second stages are located at the final stage. and a third series of memory circuits M3. M6. M.

ES+, ES2, and ESs are input to one of the reset input terminals from the multi-disk deck (1), respectively.

The outputs of other series at the same level are applied to the remaining two reset input terminals as reset inputs. R3□, R82, and R33 are information search request I-signals given from terminals T□ to T3 corresponding to each series, and here, R8, is sent to the first terminal T1, and R82 is sent to the second terminal T2. .

And R83 corresponds to the third terminal T, respectively.

If the signals are input in the order of R8, R82, and R33 in the 17th column, a logical "1" is stored in each series in that order,
They are output in the order they are remembered.

Next, the operation of the circuit (5) shown in FIG. 2 will be explained.

The transmission signals of each series may be input in any order, but for simplicity, the first signal R8 (i.e., input from the terminal TI, t, = signal for information retrieval) is included in the first series. A case will be explained in which a signal (used to determine the order of requests) is input.

First, the input terminal of the memory circuit M1 of the first series is inputted to the input terminal R3, which is a logical "1", and the memory circuit is set to "1", and the next The stage circuit M2 is set to "1", and the output of this circuit M2 sets the final stage circuit M3 to "11". The output of that (7M) is applied to the multi-optical disk deck (1).

That is, the first input signal R8 is given to deck (1) with priority.

Here, to explain the signal flow 1 in each of the memory circuits MM+2M22M3, Ml is set by the signal input to the circuit M, and an output of "1" is generated at the output terminal. The output is sent to the input terminal of circuit D M2 (O] and M2 is connected to Sera), and it is branched into two.
Memory circuit M4. of another series at the same level. M, In addition to the set input terminal, lock the memory circuits at the same position in other series.

The output of M2 is sent to the next final stage circuit M3 to set M3 17. The output is given to deck (1), but 2M
The output of M6.3 is the same as the case of M2. M, lock t/J Furthermore, the above-mentioned M2
Reset it.

After the output of M3 is sent to deck (1), M3 is reset by a signal ES generated from deck (1) after reading the information, thereby changing from ``1'' to [0-1.

In this way, in this episode * f5), the first signal input to a specific series is used to nudge the circuits at the same level in other series, releasing the circuits that are locked to the signal advancing one stage. , when the second signal arrives in another stream, it is processed one step later than the first signal, stored in the input order of No. 4B, and taken out in that order.

Therefore, if terminals T, , T2. Information retrieval is performed in the order of T3, and if the first is the signal Sl, then S2. It is applied to the control circuit (4) in the order of S3. The control circuit (4) memorizes what kind of information each terminal is searching for, and also sends signals R81 to R83 for determining the ranking in the order of requests, and signals R3, to R8.
3 to generate search information signals DS, -DS, and the R8 to R83 are applied to the circuit (5) described above in correspondence with the terminal Rifnis I. On the other hand, search information signal D
S1-r) S and C-r are applied to the multi-optical disk deck (1) in accordance with the flow of signals R3, -R3°.

A multi-optical disk deck into which the above two signals are input (
1) switches the corresponding information to the required optical disc in the order of requests, reads the desired information, and obtains the information;
~D3 is output to the control circuit (4). The information ~D read out from the optical disk in this way is sent to the requesting terminal via the control circuit (4) and the bus network (3) in FIG.

A temporary file is stored in the optical disk (tor) of each terminal. Therefore, turn on the power to each terminal
If the deck on which the optical disk TO+' is installed is activated, the information stored in the optical disks OD r to OD, 1 can be recorded on the terminal side optical disk during lunch break or at night.

By the way, in many workplaces, there are materials that are reserved the day before and want to be obtained the next day, or materials that are needed a few hours later.
There are a lot of materials that will be needed in a week,
It is not necessary to print out such materials immediately upon request, but it is sufficient that each material is created by the time it is needed. Therefore, if you file information on an optical disk at hand, you can create materials at any time without having to think about other terminals. .

From this viewpoint, this invention is extremely effective.

Note that if information is filed on an optical disk provided on the terminal side as in the present invention, the information can be reproduced according to the convenience of the terminal side, thereby expanding the range of practical applications.

FIG. 3 shows another example of this invention, in which the control circuit # (
41 and a clock (6), in which case the control circuit (4) is time-controlled by a signal (7) generated from the clock (6).

With this configuration, the control circuit (4) can be time-controlled. It should be noted that the multi-deck (), the file controller 2), and the terminals 71 to T3 are controlled in whole or in part by their own microcomputers or personal computers. .
