Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an information processing system that organically combines a microfilm and an optical disk (including a magneto-optical disk).

BACKGROUND ART A plurality of documents (literatures) consisting of one unit of image information generated in large quantities are recorded at high density on microfilm, and necessary information can be easily obtained from this microfilm. Typically,
For example, it is known that one patent publication consists of multiple pages, the information on each page is recorded on a frame by frame basis on a microfilm, and information is searched using the microfilm on which multiple patent publications are recorded. . The first page of this patent publication records the name and classification of the invention, the applicant, the scope of claims, etc., and the second and subsequent pages contain a detailed description of the invention and drawings.

When using a microfilm on which one page of this patent publication is recorded frame by frame, use the microfilm search device attached to the reader printer to find the frame of the first page of the desired patent publication on the microfilm. I searched for it, looked at the frame on the first page on the screen, considered whether this patent publication was necessary, and, if necessary, obtained a copy of it.

By the way, microfilm is ideal for permanent preservation, but microfilm retrieval devices generally have a slow retrieval speed, resulting in a problem of poor working efficiency. In particular, it takes a very long time to search a large number of patent publications, and other users are unable to use the device for a long time.

On the other hand, recently, instead of the above-mentioned microfile system, an electronic file system using an optical disk has been used.This electronic file system stores information in the form of digital signals, making it suitable for high-speed retrieval. It has special features. On the other hand, this electronic file system has a slow input speed because it reads the original and converts it into a digital signal, and it does not have a track record of long-term storage stability compared to microfilm, which has a long-term storage stability of 100 years. There is a problem in that film is not recognized as having legal evidence.

The purpose of the present invention is to organically integrate a microfilm as a safe visible file that allows image information to be confirmed with the human eye and an optical disk that allows high-speed retrieval of image information, and to provide information processing that uses both in a mutually complementary manner. The goal is to provide a system. Another object of the present invention is to provide an information processing system that can integrate and utilize the advantages of microfilm and optical disks.

A further object of the present invention is to provide an information processing system capable of operating a microfile system and an optical disk system as one system.

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows an information retrieval device to which the present invention is applied. Reference numeral 1 denotes a control circuit, which is comprised of a microcomputer that performs various controls. Reference numeral 2 denotes a microfilm retrieval device, which includes a roll-shaped microfilm file recording a large amount of information, such as patent publications, and a retrieval device for retrieving desired information in the microfilm file. 3 is a disk search device that retrieves a file such as an optical disk or magneto-optical disk in which only the information on the first page of a patent publication is digitized and recorded, and the desired information on the disk. It has a search device for searching. 4 is an input device consisting of a keyboard,
Search data such as a desired microfilm number and an address number of desired information in this microfilm are input into this input device,
When the search data is input and a search start is commanded, the microfilm search device 2 and the disk search device 3 are activated.
Desired information on the microfilm and disk is retrieved.

Note that any frame on the microfilm can be selected as the frame to be recorded on the disc.

Reference numeral 5 represents a display device for displaying information retrieved by the disk device 3, and reference numeral 6 represents a printing device for printing information retrieved by the microfilm retrieval device 2. The display device 5 includes, for example, a high-resolution cathode ray tube, a liquid crystal display, etc., and the printer device 6

The film is sent out from the cartridge 10 by the pinch roller 12, sent to the take-up reel 15 by a film guide member (not shown) and guide rollers 13, 14, and wound onto the take-up reel 15.

Microfilm F has frames recording a large number of patent publications in page order, a frame mark m1 recorded on the bottom side of each frame, and a subject mark m2 recorded on the top side of the frame recording the information on the first page of each patent publication. and has. The microfilm F is illuminated by a lamp at a predetermined position, and the information of the illuminated frame is imaged by a lens 17 onto a line sensor 18 such as a CCD (charge coupled device). Information is read. 20 is a comma mark
A frame detector 21 detects m1, and a subject mark detector 21 detects subject mark m2.

The frame mark m1 and the subject mark m2 have different densities from the surrounding areas, and when the mark recording section of the microfilm passes between the lamp 16 and each detector 20, 21, the frame mark detector 20 and the subject mark detector 2
The light incident on the detector 1 is interrupted by the marks, and each detector outputs a mark signal. Information on a desired item can be retrieved by counting the item mark signal output when the item mark detector 21 detects an item mark using a calculator. The details of the search device are known in Japanese Patent Application Laid-Open No. 56-54428, so the explanation will be omitted. A large number of microfilms are stored in the microfile, and the search device 2 can select a desired microfilm.

When desired information is retrieved and placed at a predetermined position (illumination position), the line sensor 18 converts this information into an electrical signal and reads it. This information signal is sent to the printing device 6, and if the printing device is a laser beam printer, the laser beam is modulated based on the information signal, and the modulated laser beam is imaged and scanned on the photoreceptor, Copy images can be obtained using the electrophotographic process.

FIG. 3 shows an example of a disk retrieval device using a magneto-optical disk. In FIG. 3, a disk-shaped disk 50 has Gd and
A magnetic film composed of Tb, Fe, etc. is deposited by sputtering or the like. During recording, a light beam modulated based on information emitted from a laser beam 51 is made into parallel light by a collimator lens 52, passes through a polarizer 53 and a beam splitter 54, and is then collimated onto the surface of the disk 50 using a condensing lens 55. The beam is focused into a beam spot with a diameter of approximately 1 μm. Here, the magnetic film of the disk 50 is magnetized in advance with its orientation aligned in the vertical direction, and the direction of magnetization is reflected by the irradiation with the laser beam, so that the image information and search data are converted into bits 60 in FIG. It is recorded on a disk.

On the other hand, during reproduction, a light beam of constant intensity is emitted from the laser light source 51, converted into linearly polarized light by the polarizer 53, and irradiated onto the bit string formed on the disk 50. Then, the direction of the reflected light from the disk 50, which is optically rotated according to the recorded information by the magnetic force effect, is changed by the beam splitter 54, and the polarizer 56
The signal is guided to the light receiving element 57 through the light receiving element 57, the signal is detected, and the recorded image information is reproduced by the signal processing circuit 58.

In the above disk, the interval between bit rows (track pitch) is 2 μm, and the diameter of the disk is 100 μm.
When recording from mm to 200mm, approximately 2Gbit of information can be recorded, and A4 size image information can be recorded at 16pels.
It can store approximately 125 sheets. This recorded image information can be arbitrarily searched (randomly accessed) by moving an optical system as shown in FIG. 3 in the radial direction of the disk relative to the disk. Furthermore, the above-mentioned recording can be easily erased by applying a strong magnetic field that matches the magnetization direction before recording to the disk.

A large number of disks are stored in the disk file, and a desired disk can be selected using the disk search device.

If the information output speed of the microfilm retrieval device 2 and the information output speed of the printing device 6 are the same,
The information read by the microfilm retrieval device 2 may be directly sent to the printing device 6 and printed without going through the memory 103.

Next, the search operation of the information search device shown in FIG. 1 will be explained with reference to the flowchart shown in FIG. In Figure 6,
First, turn on the power switch and set the device to its initial state in step 1. Next, in step 2, search data for desired information to be searched, such as a search number (patent number), is input into the input device 4, and a search start key on the input device is pressed to instruct the start of the search. The input search number is sent to the microfilm search device 2 and the disk search device 3 through the control circuit 1, and in step 3, the microfilm search device 2
Then, the disk search device 3 is activated and starts a search operation.

The disk search device 3 searches for desired information (information on the first page of the desired patent publication) corresponding to the search number, and in step 5 the searched information is read by the light receiving element 57 and converted into an electrical signal. This information signal is sent to the display device 5 via the control circuit 1,
The information retrieved by the disk device in step 6 is displayed on the display device 5. The user looks at the information displayed on the display device 5, that is, the information on the first page of the desired patent publication, examines this information, and decides whether or not to print.

If it is not necessary to print this information, the disk retrieval device and the microfilm retrieval device can be reset to their initial states, and new retrieval data can be entered into the input device.

If it is necessary to print this information, the print command switch of the input device 4 is turned on in step 7.

When the print command switch is turned on, it is checked in step 8 whether the microfilm retrieval device 2 has retrieved the desired information.

When desired information is retrieved by the microfilm retrieval device 2, in step 9, the information retrieved by the microfilm retrieval device 2 is read by the line sensor 18 and converted into a binary information signal.
This information signal is sent to the printing device 6 via the control circuit 1, and in step 10, the printing device 6 prints the information retrieved by the microfilm retrieval device 2.

If the desired patent publication is composed of a plurality of frames, the microfilm search device 2 sequentially reads the information of each frame and sends the information signal of each frame to the printing device 6. The printing device 6 sequentially prints the information of each frame of the desired patent publication sent from the microfilm search device. When printing of each frame of the desired patent publication is completed in step 11, the process returns to the initial state and prepares for the next new search operation.

The search speed of the disk search device is about 0.5 seconds to 2 seconds, and when a search start command is issued, the desired information of the disk width is displayed on the display device 5 in a short time. Therefore, after starting a search, the user can immediately view the desired information displayed, that is, the information on the first page of the patent publication, and consider whether this information is necessary. On the other hand, although the search speed of the microfilm search device is slower than that of the disk search device, the information searched by the disk device can be used before the microfilm search device searches for the desired information. Until the information is searched, the displayed desired information can be used to perform necessary considerations, and time can be used effectively.

In addition, since all information is recorded on microfilm, it can be saved forever, and even if the information recorded on the disc deteriorates, it can be recorded on the disc again using microfilm. You can handle information with peace of mind.

In the above embodiment, the information on the microfilm is converted into an electrical signal and this signal is sent to the printing device for printing. However, the information searched by the microfilm search device is projected onto a known photoreceptor using an optical lens. It may also be possible to print it.

A roll film, a fixed film, an aperture card, etc. can be used as the microfilm. Further, as the microfilm search device, a known film search device, aperture card selector, etc. can be used.

As described above, according to the present invention, image information and common search data are recorded on a microfilm and an optical disk, and both can be used as one system. can be used effectively and a mutually complementary system can be realized. In addition, the advantages of microfilm, namely, the high speed of inputting original information, long-term image storage, high-speed mass copying, and ability to provide image evidence, are recognized, and the advantages of optical disks, namely, high speed. The ability to search, the ability to use manuscript information immediately after input, and the ability to transmit image information can be mutually utilized, and an appropriate storage state can be selected depending on the type of information, frequency of use, nature, etc. . Furthermore, since the information on the microfilm and the information on the optical disk can be processed completely equivalently, the trouble of using two different files separately is eliminated, and moreover, it is possible to obtain an output suitable for the characteristics of each film.
