Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a patent information retrieval using a disk device in which patent information (including other industrial property information such as utility models, designs, trademarks, etc.) is recorded on a digital data recording disk. Regarding the device.

[0002]

2. Description of the Related Art Most conventional patent information retrieval devices use a recording medium such as a magnetic tape or a CD-ROM. Random access is difficult in the magnetic tape, and the capacity of the CD-ROM is small, so that the searching method and the utilizing method are limited. Moreover, since the appearance of a large-capacity recording medium was not expected, a search method for making full use of a large-capacity disk could not be considered and was not disclosed.

The following is a list of conventional patent information retrieval devices applied so far. JP-A-6-301732 and JP-A-6-139.
No. 291, the bibliographic items, abstracts, and claims of the patent information in the CD-ROM are filed in another high-speed storage device,
Since the keyword search is performed for each item, high-speed search is possible. This eliminates the need to access a series of document information in the CD-ROM one by one, and has an advantage in that the search range is narrowed down in advance. For this purpose, a hard disk drive is required in addition to a CD-ROM reader, which is very expensive. In a hard disk, it is common to have a plurality of floating magnetic heads, but they are simply mounted in stacked disk units.

[0004] Japanese Unexamined Patent Application Publication No. 5-135109 is a kind of search support device, which calculates the degree of similarity (classification code, keyword, etc.) between the content of the target application and the patent information in the existing database to improve the search efficiency. System.

Japanese Patent Laid-Open No. 6-139127 discloses a system in which only desired predetermined data is taken out from a CD-ROM and only the taken-out data is stored in a floppy disk to create a database of its own. The capacity of this floppy disk is as small as about 1.2 Mbytes, and the system uses a small capacity recording medium.

The conventional disk system is usually composed of one pickup, but there is a disk device using two pickups, which are listed below. SUMMARY OF THE INVENTION In this conventional application, two pickups are used for video and audio, respectively. In this example, the area A of one disc is used as the video portion and the area B is used as the audio portion or the data portion. The image is
The image is recorded on the disc from the image recording processing unit via the optical head. Voice is recorded from the voice recording unit via the optical head. In the reproducing system, an optical head reproduces an image through an image reproducing processor, and one optical head reproduces an audio through an audio processor. The purpose is to output sound when the image is a still image, and is not expected to be applied to a database.

[Patent Document 1] Japanese Patent Application Laid-Open No. 7-37368 This is intended for a data search device using two pickups in order to enable high-speed processing. However, since there is no large-capacity disc, it has a data area on both sides of the disc and has pickups on the front and back sides of the disc. Similar to the above, application to databases is not expected.

[0008]

However, although the above-mentioned conventional patent information retrieval device aims to improve the convenience of retrieval, there is no recording medium of low cost and large capacity. In addition, only one item can be searched and the result can be confirmed, and a plurality of items cannot be processed in parallel or the contents can be confirmed at the same time.

Further, one piece of patent information is only recorded in the order of description, and it is not possible to apply various search methods.

Further, in patent information, it is most efficient to compare drawings and text information at the same time for checking, but in the past, since most of them are single screens and the memory capacity is small, retrieval of patent information is done. In the field, a search device that realizes this has not been realized.

However, in recent years, a DVD (Digital Video Disc) has been developed as a large-capacity disc device, and its capacity is about 5 Gbytes. This is about 1.2 Mbytes of the capacity of the floppy disk used in the conventional device,
The storage capacity is about 5000 times, and the search method must be completely different.

Therefore, it is an object of the present invention to provide a patent information retrieval device which utilizes the disc device having a large capacity such as a DVD and which is fully utilized at a low cost and a high retrieval efficiency. .
