The image reading device 15 scans the original 116 and reads the original 1!16.
It obtains electrical signals corresponding to the above image information, and is mainly composed of a COD line image sensor and the like.

The optical disk device 20 sequentially stores image information read by the image reading device 15 on an optical disk 21 and reads necessary image information from the optical disk 21. A storage means 120 shown in FIG. 1 is configured.

As shown in FIG. 3, the optical disc 21 has a donut-shaped metal coating layer such as tellurium or bismuth coated on the surface of a circular substrate made of glass or plastic, for example. A notch, ie, a reference position mark 21a, is provided near the center. Further, the optical disc 21 is divided into 32 sectors "0 to 31" with the reference position mark 21a set to "0". Furthermore, the optical disc 21 is divided into image information groups (up to eight types) each consisting of search data with different title structure definitions, and one image information group constitutes one binder. For example, as shown in FIG. 3, each image information group is divided into binders O to 7.

The magnetic disk device f25 stores search data for each piece of image information, consisting of a search code transmitted from the terminal unit 200 and a storage address on the optical disk 21 corresponding to this search code, on the magnetic disk 26 for each optical disk 21. It is something to do. This magnetic disk device! 25, magnetic disk 26, and CPU 1, search means 110 of FIG.
is configured.

The communication control device 30 receives search data from the terminal section 200 and transmits image information corresponding to this search data to the corresponding terminal section 200. By this communication control device 30 and CPLll, the output means 1 of FIG.
30 are configured.

On the other hand, the terminal unit 200 connected to the center unit 100 via the communication line 300 has a main control bag M40° keyboard 50.
．． CRT display55. Recording device 60. Floppy disk device 65. It includes a magnetic disk device 70 and a communication control device 75.

The main control device 40, like the main control device 10 of the center section 100, has a CPU 41 serving as the core of υItll, and a memory annotation corresponding to image information for several pages of an A4 size document.
A page buffer 43 and the like for temporarily storing image information from the center section 100 is provided.

From the keyboard 50, unique search codes and various operation commands corresponding to each piece of image information are input.

On the CRT disk display 55, image information read from the optical disk 21 of the center section 100, search data input from the keyboard 50, etc. are displayed. Further, this image & information is output as a hard copy by the storage device 60.

The floppy disk device 65 stores and plays back a floppy disk 66 that can store a plurality of search data in advance, and the floppy disk device 65, the floppy disk 66, and the CPU 41 constitute the search data storage means 210 shown in FIG. has been done. The search data is stored on the floppy disk 66 from the keyboard 50, Haku's personal computer, or the like.

Therefore, if you use the free time of the keyboard 50 and store search data from a personal computer or the like on the floppy disk 66 in advance, and then insert this floppy disk 66 into the floppy disk device 65, the search data will be automatically stored from now on. Since the information is output to the center unit, search data input processing and actual search processing can be separated. Therefore, during the search process, the search process can be performed in parallel with other tasks such as recording information using the keyboard 50.

The search data storage area of this floppy disk 66 is structured as shown in FIG.

In other words, there is a storage area a in which search status (status information) such as success or failure of search results for each code and error information are stored, and a storage area a in which the search status (status information) such as success or failure of search results for each code is stored; Storage area b where the name of the center department to be searched is stored, cabinet name as a search code for image information to be searched for, binder name, document title, page,
Storage areas c, d, and e in which the number of printed copies is stored, respectively.

"1g1 A storage area where the number of additional images or characters to be combined is stored.H2 A storage area i in which additional information as the content of images or characters to be combined is stored.It is stored in the storage area i. In the case of an add-on title, the additional information includes the number of columns, 1 number of lines, 1 number of characters, 1 composition type, and character strings or their contents, which specify the position of characters on the page.

The magnetic disk device 70 of the terminal unit 200 stores search data input and reproduced from the floppy disk 66 in a batch on a magnetic disk 71 . This search data is subjected to grooving processing as shown below in the magnetic disk 71 and then output to the center section 100 via the communication line 300.

That is, as shown in FIG. 5, the search data storage area in the magnetic disk 71 is composed of a center section name storage area, each cabinet storage area, a binder name storage area, and an M-class title storage area, and these are arranged in this order. It has a hierarchical structure. Therefore, the search data arbitrarily stored on the floppy disk 66 is classified on the magnetic disk 71 by center part (b1 to bn), and each center part -bn
are roughly classified into cabinets c1-cn, and each cabinet 01-cn is classified into binder d
Each binder d, to dn is classified to stores and titles e1 to en.

Thereby, even if the search data in the floppy disk 66 is arbitrarily created, it can be selected and transmitted to the center section.

Additionally, the installation status can be determined for each cabinet name at once. Furthermore, it is possible to search for each part of the binder at once, and the corresponding image information for each document and title can be retrieved from the optical disc 21.
It can be read from.

Next, the operation will be explained according to the flowchart shown in FIG.

The terminal iioo is powered on, and the floppy disk 66 is loaded into the floppy disk device 65, and the magnetic disk 71 is loaded into the magnetic disk device 70 (business start processing). A plurality of search data are inputted from a personal computer, keyboard 50, etc. and stored in advance on the floppy disk 66. Then, all unprocessed data in the file is read from the floppy disk 66 (step 81).

Grooving processing of the read data is then executed (step S2). As described above, this process is to group data on the magnetic disk 71 by center type, cabinet type, etc.

Next, the first center section 100 is selected and connected (step 33). The corresponding search data is then transmitted to the first center section 100 via the communication line 300 (step 84).

The center unit 100 extracts the first search output data from the received search data (step S5). Then, in the CPLll, search information that matches the retrieved search data, that is, the cabinet name, binder name, document title, etc. as search information, is sent to the center unit 1.
00 is stored on the magnetic disk 26. As a result, if the corresponding cabinet, that is, the optical disk is already installed, and the search information matches, the optical disk is loaded according to a command from the CPLll! 20, image information is read from the corresponding optical disc 21 based on the file name, binder name, document title, page number, etc. (step 86). The CPU 1 supplies this image information to the compression/expansion circuit 7 for each scanning line, and performs the well-known Ml(
(Seven def? Ido Hoffmann) Bandwidth expansion is performed by inverse transformation and this image information is supplied to the page buffer 5. When all of the image information for one page reproduced in this way is stored in the page buffer 5, this one page of image information is transferred to the terminal unit 2 via the communication control device 30 in accordance with a command from the CPU i.
00 (step 87) The terminal section 200 transmits one page of image information from the center section 100 to the communication control device M7.
5, this image information is displayed as an image on the CRT display 55 (step S8), and a specified number of hard copies are output from the storage device 60.

The above steps S3 to 88 are repeated,
When all the search codes related to the first center station 100 have been processed, the connection with the center unit 100 is made 173111 (step 510). Next, if there is a search request for the second center unit b2, the second center station b2 is connected to the center station b2. In order to connect the line to the center section b2 (step S3), the following processes from steps S4 to 810 are executed.

When all search output processing is completed, the results are self-printed and stored in the corresponding search output data storage area a of the floppy disk 66 as status information.

In any step of the series of search processes described above, the operator can arbitrarily interrupt or restart the process or skip records on the floppy disk 66 while monitoring the image process on the CRT display 55, for example.

In this way, according to the present embodiment, by simply setting the floppy disk 66 on which a large amount of search data has been inputted in advance into the floppy disk device 65, the search process can be executed for each center section 100 on a self-help basis. Therefore, search data input processing and actual search processing can be separated, time required for operator intervention can be reduced, and communication line usage efficiency can also be improved.

[Effects of the Invention] As explained above, according to the present invention, search data for searching information stored in the storage means of the center section is stored in advance in the search data storage means, and the search data is stored in accordance with the search data. Since the system is configured to sequentially search for information, input of search data and actual search processing can be separated. Therefore, it is possible to reduce the input device occupation and busy time due to operator intervention, and the reduced occupied time can be used for other processing, improving the usability of the system.
