Abstract

PURPOSE:To smoothen a retrieving action by transmitting and displaying the catalogue or index of data base to a microfilm automatic retrieving device when an interruption command is inputted through a keyboard. CONSTITUTION:When a key operation is command through the keyboard 11, this information sets the status information of response information to an infor mation retrieving computer 20 from the microfilm automatic retrieving device 10 to '1', for instance, whereby the presence of the key operation is reported to the information retrieving computer 20. After it accesses the catalogue or index of the data base from the data base 21 so as to store provisionally said catalogue or index in memory, etc., it transmits said catalogue or index as a command to the microfilm automatic retrieving device 10, and data of the catalogue or index is displayed on a CRT12.

Description

DETAILED DESCRIPTION OF THE INVENTION (Technical Field of the Invention) The present invention relates to an interrupt processing method in an automatic search system.

(Technical background of the invention and its problems) Automatic microfilm retrieval machines are already available on the market, and by connecting the automatic microfilm retrieval machine to an information retrieval computer, automatic microfilm retrieval can be performed at high speed and on a large scale. Systems that do this by capacity are emerging. However, in conventional automatic retrieval systems, it has not been possible to access the catalog or index of a database held by an information retrieval computer from a microfilm automatic retrieval machine, which is a terminal. Therefore, if you need a catalog or index of the database, you can call the information search computer located at the center from the terminal, have the contents of the database printed, and then send the printed manuscript by fax, etc. It was necessary to have it transmitted.

(Object of the invention) This invention was made under the above circumstances,
An object of the present invention is to provide an interrupt processing method that allows an automatic search machine, which is a terminal, to freely access a catalog or index of a database connected to an information retrieval computer at a center.

(Summary of the Invention) The present invention relates to an interrupt processing method in an automatic retrieval system comprising an automatic microfilm retrieval machine having a keyboard and an information retrieval computer that retrieves a database. When a command is input, a catalog or index of the database is sent to the automatic microfilm search machine and displayed, thereby facilitating the search operation.

(Embodiment of the invention) Figure 1 shows the configuration of an automatic microfilm search system. a10 has a keyboard 11 operated by a searcher, and a CRT 12 for displaying search results and the like on a screen. This microfilm automatic search machine IO is connected to the information search computer 20 via a data connection line such as R5232C.
The information retrieval computer 20 has a database 21, and data in the database 21 can be changed by operating the keyboard 22, etc., and the data can be used to search from the microfilm automatic retrieval alO.

In such a configuration, FIG. 2 shows the state of communication between the microfilm automatic retrieval alO and the information retrieval computer 20.
Address and status information S? from 0 to the microfilm automatic search machine 10? By sending a command l consisting of
Search #l is executed in the microfilm automatic search aIO. When search #l is started, the automatic microfilm retrieval machine IO sends its response information 2 to the information retrieval computer 20, and the information retrieval computer 2
0 sends command 3 for performing search #2 as the next search command. In this case, microfilm automatic search machine 1
0 is executing search #l, so it sends information 4 indicating that it is "BUSY" to the information retrieval computer 20, and after receiving that information, the computer 20 executes search #l again.
2, send command 5 to the microfilm automatic retrieval machine IO. At this time, the automatic microfilm search machine 10 is still executing search #1 operation, so "B"
The response information 6 indicating "tlJY" is sent back to the information retrieval computer 20, and when the retrieval operation of retrieval #1 is completed in the microfilm automatic retrieval machine lO by repeating such response information, the information is sent back from the microfilm automatic retrieval machine a10. Status information S of response information to the search computer 20
For example, by setting T to 1'', the information retrieval computer 20 is notified that the search #l has ended.Then, in response to commands sent from the information retrieval computer 20 at predetermined intervals, the microfilm automatic retrieval machine 1O performs the following operations. The commanded search #2 will now begin.

For example, if you do not know what processing action to take next using the keyboard 11 during search #1, for example, if you instruct key operation Kl on the keyboard 11, this information will be transferred from the automatic microfilm retrieval machine 10 to the information retrieval computer 20. For example, the state information ST of the response information to “1”
By doing so, the information retrieval computer 20 is notified that the key operation Kl has been performed. As a result, the information retrieval computer 20 accesses the database catalog or index from the database 21 and temporarily stores it in a memory or the like, and then sends it to the microfilm automatic retrieval machine 10 as command 7 and stores the catalog or index data on the CRT 12. Make it visible. In this case, if all the catalog or index information cannot be transmitted in one communication, the information is repeatedly sent to the microfilm automatic search a110 and all data is CR
Enable display on TIO.

A request to display the catalog or index of the database 21 using the key operation Kl from the keyboard 11 is possible regardless of the operating state of the automatic microfilm retrieval Ia1G, and can be made between the automatic microfilm retrieval machine IO and the information retrieval computer. The microfilm automatic search a10 side of the terminal can perform an interrupt request to the center to automatically retrieve the catalog or index of the database 21. Since the information can be accessed freely, the search operation can be carried out smoothly.

(Effects of the Invention) As described above, according to the interrupt processing method of the present invention, periodic communication is performed between the automatic microfilm retrieval machine and the information retrieval computer, and this communication is used to By operating the keyboard on the side, the catalog or index of the center's database can be accessed freely, allowing for smooth search operations.
