Abstract

PURPOSE:To use mutually retrieved results by retrieving information of a microfilm automatic retrieving device being one terminal equipment from a microfilm automatic retrieving device being other terminal equipment. CONSTITUTION:When the microfilm automatic retrieving device 30 retrieves microfilm information which said device 30 does not own, the effect is key- inputed through a keyboard 32, and its contents are transmitted as a command to the information retrieving computer 1 at the center. Said computer 1 transmits the command to the microfilm automatic retrieving device 10 having information, displays it on a CRT33 and stores it in a page memory 13.

Description

DETAILED DESCRIPTION OF THE INVENTION (Technical Field of the Invention) The present invention relates to a microfilm retrieval system using an information retrieval computer.

(Technical background of the invention and its problems) Automatic microfilm retrieval machines are widely used, and a plurality of automatic microfilm retrieval machines are used as terminals, and a computer at the center manages a large number of terminals as a whole. Systems that control and search large amounts of information at high speed have already appeared. However, in the conventional microfilm retrieval system, it is not possible to access the contents of other automatic retrieval machines from one automatic retrieval machine, which is a terminal, and if necessary, contact the center computer by telephone etc. After accessing other terminals from the center to search for the necessary information, the search results were transmitted by facsimile or other means to the automatic search machine that requested it. For this reason, it has not been possible to search for desired information quickly and easily.

(Object of the invention) This invention was made under the above circumstances,
The purpose of this invention is to search for information from one terminal, which is an automatic microfilm search machine, to another terminal, which is an automatic microfilm search machine, and to enable mutual use of the search results. The goal is to provide a system.

(Summary of the Invention) This invention combines a plurality of automatic microfilm retrieval machines each having a keyboard and a built-in page memory, and an information retrieval computer connected to the plurality of automatic microfilm retrieval machines. This relates to an automatic retrieval system consisting of: when one of the automatic microfilm retrieval machines requests retrieval information from another automatic microfilm retrieval machine, the information retrieval computer Then, from the above information retrieval computer, give a search command to the requested machine, perform the search, store the search results in the page memory of the requested search machine, and then use the information retrieval machine described in L. Information is transmitted to the request search machine via a computer.

(Embodiment of the Invention) Fig. 1 shows an example of the microfilm retrieval system of the present invention, in which an information retrieval computer 1 is placed at the center, and this information retrieval computer stores information such as R5232C. A plurality of automatic microfilm retrieval machines 10, 20, 30 are connected as terminals by transmission lines. -P Microfilm automatic search alO~30 each have the same configuration, and each has a built-in page memory 11, 21.31, and a keyboard 12, 22.32 is externally connected for operation by an operator. , CRT+3.23 for displaying search results etc.
．． 33 are connected. Microfilm automatic retrieval equipment 10, 20, 30 is the key dopo 12, 22, respectively
．． By operating 32, automatic warehouse (not shown)
Microfilm was delivered from etc.

The search results are displayed on CRTs 13, 23, and 33.

Figure F+2 shows the state of communication between the information retrieval computer 1 and the two automatic microfilm search machines 10 and 30. When searching for , the user inputs a key on the keyboard 32 and transmits the content to the information retrieval computer 1 at the center as a command C1. The information retrieval computer 1 analyzes the contents of the received command C1 and determines which terminal holds the requested information. Then, the information retrieval computer 1 sends a command C2 to the microfilm automatic retrieval machine 10 that holds the information, and the automatic retrieval machine 10 performs a search PI and displays the search results on the CRT 13. Thereafter, the information searched by the command C3 sent from the information retrieval computer 1 after a predetermined period of time or at predetermined intervals is stored in the page memory 11, and the information stored in this page memory 11 is sent to the page memory 11 by the command C4. The information is transmitted to the information retrieval computer 1 as an information retrieval computer. The information retrieval computer l receives the transmitted command C4.
The content is analyzed and the information is transmitted to the automatic search machine 30, which is the terminal that made the request, using command C5.The automatic search machine 30 displays the sent information on the CRT 33, and also displays the information on the page memory 31. It will be stored in.

In this way, by requesting necessary information from the automatic search machine, which is a terminal, to the information search computer 1 at the center, the information search computer 1 can determine which terminal holds the information. It is possible to access the search machine that holds the information, and automatically send the search results to the automatic search machine that requested the information.

In the above embodiment, there are three terminals for one center computer, but the number of terminals is arbitrary, and microfilm information can be freely searched between any terminals. It becomes possible to search for large amounts of information.

(Effects of the Invention) As described above, according to the microfilm retrieval system of the present invention, an automatic microfilm retrieval machine serving as a terminal device can access other automatic microfilm retrieval machines via a computer at the center. It is possible to quickly and automatically search for large amounts of information that exceed the amount one owns.
