The content of the input information and/or the searched processing content is displayed using an output device that outputs the content of the input information and/or the searched processing content.

[Example] Hereinafter, an example of the present invention will be described in detail using the drawings.

FIG. 1 is a block diagram showing an example of the configuration of a data search device according to the present invention.

As shown in the figure, an input device 1 such as a keyboard or mouse
is connected to a programmable processing unit 212 such as a device dedicated to the search unit 21 or a general-purpose personal computer. This arithmetic processing device 2 is connected to an output device 3 such as a CRT that displays input contents and search results, and an output device 4 such as a printer that prints input contents and search results on paper.
Additionally, there is a rewritable memory 5 of several tens to hundreds of Mbytes that serves as a database, a read-only large-capacity memory 6 for database backup and long-term data updates, and a large-capacity read-only memory 6 for short-term database data updates. A small capacity memory 7 that can only be read is connected.

As the replaceable memory 5, a magnetic or magneto-optical fixed disk, a semiconductor memory, or the like can be used.

As the read-only large capacity memory 6, a magnetic tape memory or an optical disk memory from which information is optically read can be used.

As the read-only small-capacity memory 7, there are card-like media that store information using different optical characteristics (hereinafter referred to as optical card memory), and IC cards in which conductive memory is embedded in a card-like substrate. Memory, floppy disk, etc. can be used.

Hereinafter, as a specific example of the present invention, the data search device of the present invention will be described in detail by taking up a blacklist search method.

The blacklist is used to check for unauthorized use of credit cards, etc., and is a list of credit cards that have been lost or stolen. Become. At a credit card affiliated store, the credit card being used is checked against a blacklist to check whether it has been used fraudulently. Therefore, new data must be constantly updated.

FIG. 2 is a block diagram for explaining the system of the blacklist search device.

FIG. 3 is a flowchart for explaining a method of inputting information to the blacklist search device.

Affiliated stores are equipped with a blacklist search device system as shown in Figure 2. In FIG. 2, 8 is a personal computer main body, 9 is an input device, and 10 is a C
RT, 11 is a printer, 12 is a magnetic fixed disk memory serving as a database, 13 is an optical disk memory reader, 14 is an optical disk memory, 15 is an optical card memory reader, and 16 is an optical card memory.

Now, a method of inputting data into the blacklist search device will be explained with reference to FIG.

First, the latest blacklist list is recorded in the optical disk memory 14 and sent from the card company to a large number of member stores every month or every few months. A feature of the future disk memory 14 is that it is capable of copying a large amount of information on the order of several hundred megabytes. However, the optical disk memory cannot be used for additional recording, and it takes approximately 10-11 hours to load the data into the optical disk memory, and the price is also high. Therefore, updates using optical disk memory are performed every month or once every few months.

Blacklist data changes day by day, and there may be cases where you suffer damage due to delays in updating. Therefore, the card company sends to the optical card memory 16 data that has changed in the latest blacklist list every day or once every few days. A feature of optical card memory is that it can copy large amounts of information ranging from tens to hundreds of bytes, and data can be stored in optical card memory within one to several days. This means that the price is low.

When the member store receives only the optical disk memory 14 or the optical disk memory 14 and the optical card memory 16, the information recorded on the optical disk memory 14 is first read by the optical disk memory reader 13, and then the information recorded on the magnetic fixed disk is read. Replace it with information from the database in the memory 12, and if it is only the optical disk memory 14, save the information as is.Once reading is complete,
The optical disk memory 14 is stored as a backup until the next latest one is sent.

When the optical disk memory 14 and the optical card memory 16 are sent, the information recorded on the optical card memory 16 is also read by the optical card memory reading device ff115.
The database information stored in the magnetic fixed disk memory 12 is read by the system, and only changed data is replaced, the data is updated, and the data is saved.

Note that even if only the optical card memory 16 is sent, the member store will similarly transfer the information recorded in the optical card memory 16 to the optical card/memory/reading device 15.
An example of an optical card memory and its reading device will be described below, in which only changed data is replaced in the database of the magnetic fixed disk memory 12, the data is updated, and the data is saved.

FIG. 5(a) is a schematic plan view showing the recording format of the optical card, and FIG. 5(b) is a partially enlarged view of this recording format.

In FIG. 5(a), a recording area 22 is provided on an optical card memory 21 which is an information recording medium, and a plurality of bands 23 are formed in an array in this recording area 22. Each band 23 is formed with a large number of tracks 24 arranged. 25 indicates the initial position on the card. As shown in FIG. 5(b), each track 24 has a preamble area 32. One track in the track alignment direction (

FIG. 8 is a block diagram of a circuit for detecting the recording signal of the information track as described above.

As shown in the figure, the sensor array 30 is driven by the control signal 108 from the sensor array driver 101. Then, from the sensor array 30, an analog waveform signal 107 corresponding to the image of the track on the optical card memory 21 projected by the optical system enters the sensor array driver lot, and is sent to the binarization circuit 10 as a rough signal 109.

The information demodulation circuit 104 receives the on-track signal 114 from the identification area detection circuit 103, determines the beginning of the information, demodulates a signal modulated by, for example, MFM modulation, and sends the demodulated signal as an information signal 112 to the information acquisition circuit 10B. The end bit circuit 105 detects the end bit and sends a signal indicating the end of the information and a signal t13 indicating that the track has moved to a new track to the information acquisition circuit 106. In the information acquisition circuit 106, the above-mentioned signals 111°112.1
13, the sensor array 30 scans one track a plurality of times and captures a correct signal once from among the signals obtained.

In this way, by using the optical card memory 16 and the optical disk memory 14 from which track information is sequentially read, it is possible to correctly and quickly update the database for a large number of affiliated stores.

In the system shown in FIG. 2, since the personal computer 8 is used, in addition to software for data updating and data searching, software for managing sales slips, inventory management, etc. can also be used. Also, each result is displayed on CRTIO or printer 11. Displayed or output on h.

Next, the search procedure at member stores will be explained.

FIG. 4 is a flowchart for explaining a data retrieval method for the Blur7Crist retrieval device.

When receiving a credit card from a customer, the clerk enters information such as the card company name, customer's name, membership number, code number, etc. (this information is printed as a credit card embossment or magnetic stripe). (Since the information has already been input, a dedicated reading device may be provided to input it.)

The data search device compares the input credit card information with database data recorded in the magnetic fixed disk memory 12 to confirm whether the card has been used fraudulently.

If it is confirmed that there is no unauthorized use, sales slip processing and inventory processing are automatically performed by inputting sales items and prices manually, and the results are displayed on CRTIO. Further, the sales slip is printed out on the printer 11.

In the case of unauthorized use, the unauthorized use is displayed on the CRTIO. In this way, everything from searching to displaying items for sale can be done easily and quickly.

In the example in Section E, we have explained the blacklist as an example, but there are many searchers and there are many data updates, such as telephone directories, timetables, car parts lists, Figure 3, and leisure information. It is also suitably used as an information data retrieval device.

[Advantageous Effects of the Invention 1] As explained above, according to the data search device of the present invention, it is possible to perform a personal search easily and to update information correctly and quickly.

The invention can be suitably used in a data retrieval device for information in which there are many searchers and data is frequently updated.
