Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a record of microfilm etc. that has image information and search information for searching this image information! The present invention relates to an information search device that searches for desired image information by detecting search information on two media.

[Prior Art] In reader printers and the like, in order to search for image frames on microfilm, marks with different openings and densities are attached to the side of each image frame on the film.1. This mark is detected while the film is moving and counted by the counter.
A known method is to search for a desired image by stopping the film when the counted value matches the frame number of a desired image, and to project this image onto a screen for use.

By the way, there are various kinds of films, and there are no limitations on the recording position of the mark with respect to the image, the size of the mark, etc.

Figure 5 is a diagram showing the structure of a part of a roll-shaped microfilm. In Figure 0, which shows four types of microfilms F1 to F4, the frames on which images are recorded are arranged in a row on the microfilm F1. Then, the left edge (reference edge) of the opaque frame mark and the frame mark m1 on the bottom of each frame.
It is attached to each frame at the position where the distance from the left end (reference end) is 1.

An opaque frame mark m2 is recorded on the upper side of each frame on the microfilm F2, and this frame mark m2 is attached to each frame at a position where the distance between the left edge of frame 1 and the left edge of frame mark m2 is sentence 2. has been done.

On the microfilm F3, opaque marks ml and fn3 are recorded on the upper and lower sides of each frame, the frame mark m1 is attached to each frame, and the subject mark m3 is attached to the selected frame. Matter mark m3 is the left end of frame l and matter mark m
It is attached at a position where the distance from the left end of No. 3 is fL3, and the length in the film traveling direction is different from that of the frame mark m1.

On the microfilm F4, an opaque mark "1 + m3" is recorded on the upper side of each frame. The single mark m3 is attached to the first frame of a series of frames whose image contents are related, and the frame mark m1 is attached to the other frames. There are various types of microfilm in addition to the examples.
As shown in the figure, the recording position, size, type of mark, etc. of the mark vary depending on the film, and when searching using such a film, the user must enter the setting conditions corresponding to the film. I needed to.

For example, information corresponding to the recording position of the mark (distance it
, intersection 2. 3) By inputting information indicating the type of mark, whether the film is negative or positive, or whether the mark is transparent or opaque, etc., using a keyboard, etc., it is possible to keep the image stopped at a constant position or to correctly detect the mark. That's what I was doing. However, inputting the setting conditions is troublesome, and there is a problem that users may forget to input the setting conditions to the input device. If you make a mistake or forget an input operation, the stopping position of the image will shift and the image will not be projected at the correct position on the screen, and when copying this image, part of the image may be missing or you may not be able to search for one image correctly. This will result in an inability to do so.

[Means for Solving the Problems] The present invention aims to solve the above-mentioned conventional problems and to provide an information retrieval device that can correctly search images and stop images at an appropriate level with a simple operation. a card holding section for removably holding a memory card storing setting conditions corresponding to a recording medium having image information and search information for searching this image information; and a card holding section.

As the memory card 17, an IC card with an IC chip mounted inside a card base material, a magnetic card with a magnetic material coated on the surface of the card base material, etc. are used. Various shapes of cards can be used, such as rectangular ones, disk-shaped ones such as floppy disks, magneto-optical disks, etc.

This memory card 17 stores search information corresponding to the film, such as image polarity information indicating whether the film is negative or positive, mark density information indicating whether the mark is transparent or opaque, and whether the mark is located on the lower side of the film or Mark position information indicating whether the mark is located on either side of the upper side or on both sides;
Stop position information regarding the recording position of the mark relative to the frame (distance*11 to intersection 3), mark length, mark form information indicating the type of mark, film density, information indicating the image shooting magnification, etc. are stored. . Memory card is film F
1 to F4, and each memory card contains the above-mentioned search information specific to the corresponding film, i.e., search,
Setting conditions for copying are stored.

FIG. 4 is a flow diagram of the operation.

Next, the operation of the unimplemented example will be explained. The cartridge 11 is installed in a predetermined position in the search section, and the memory card 17 corresponding to the microfilm in the cartridge 11 is set into a predetermined card receiving section from the card insertion slot 16. When the memory card 17 is set in a predetermined position, the reader 40 detects the card 17, reads the information stored on the card, and sends this information signal to the control section 43. When the control unit 43 receives the information signal, it inputs address information (for example, frame number) of the image information to be searched into the primary keyboard 15, which controls the search operation based on this information signal during the search, and
When a search start is commanded, the film is transported.

The control unit 43 determines which of the high level and low level signals output from the mark detector 14 should be counted by the counting unit as a mark detection signal based on the mark density information stored in the memory card. For example, if the mark is transparent, high-level output signals are counted; if the mark is opaque, low-level signals are counted. The control unit 43 also determines which output signal from the mark detectors 14a and 14b should be sent to the counting unit based on the mark position information stored in the memory card. That is, film F1. In the case of mark position information corresponding to film F3, only the output signal of the mark detector 14a is sent to the counter; in the case of mark position information corresponding to film F2, only the output signal of the mark detector 14b is sent to the counter; In the case of mark position information corresponding to F3, the output signals of the mark detectors 14a and 14b are controlled to be sent to the counting section, respectively.

Further, the control unit 43 controls the image to always stop at a predetermined position based on the stop position information.

That is, the ROM of the control section 43 stores film stop data corresponding to the distances 11, 12, 13, . . . between the reference edge of the frame and the reference edge of the mark.
Step 3 reads film stop data corresponding to the stop position information stored in the memory card from the ROM, and uses this stop data to determine the time from when a mark of a desired image is detected to when the film is stopped. In other words, the image is stopped at a fixed position by changing the time from detecting the mark to activating the brake depending on the recorded position of the mark relative to the frame. Note that position correction data corresponding to the distance is stored in the ROM,
Immediately when the desired image mark is detected, the film is stopped F, and then the film is conveyed by a set amount in a predetermined direction based on the position correction data corresponding to the stop position information stored in the memory card, and the image is The stop position may also be corrected.

Further, the control unit 43 is controlled to discriminate and count mark detection signals output from the mark detector 14 based on the mark form information stored in the memory card. For example, in the case of a memory card that uses film F3, the control unit 43 counts mark detection signals output from the first mark detector 14a based on the mark form information stored in this memory card using an IT counter, and The mark detection signal output from the mark detector 14b is controlled to be counted by the second counting section.

In addition, in the case of a memory card using film F4, the control unit 43 discriminates the frame mark m1 and the subject mark m3 according to the pulse width of the mark detection signal based on the mark form information stored in this memory card, and The mark detection signal of the mark is sent to the first counting section, and the mark detection signal of the target mark is sent to the second counting section. Note that the counting section is controlled by the control section 43.
It is composed of a digital counter set in a predetermined area of the RAM.

When a desired image is retrieved, the film is stopped at a predetermined position based on the stop position information, and the desired frame is correctly projected at a predetermined position on the screen.

To copy the image of this frame, operate the print button. When a print command is given, the control unit 43 controls the printer part P based on image polarity information, density information, magnification information, etc. stored in the memory card. For example, some printers P change the polarity of the charger that charges the photoreceptor, or change either the positive or negative developer so that a positive copy image is always obtained based on the image polarity information. Decide if it will work.

Furthermore, the density of the copied image is adjusted by controlling the voltage supplied to the lamp 32 that irradiates the microfilm based on the density information, and furthermore, the projection magnification of the image is changed based on the magnification information.

The search information provided on the film is not limited to the marks used in the embodiments, but may also include eight-codes, numbers, letters, and the like.

Further, the image recording medium is not limited to microfilm, but may also be an optical disk, a magnetic disk, a magnetic tape, or the like.

[Effects] As described above, according to the present invention, mistakes in input operations,
This eliminates the fear of forgetting an input operation, allows you to always correctly search for the desired information, and also allows you to stop at a fixed position, making the operation extremely simple.
