DETAILED DESCRIPTION OF THE INVENTION The present invention provides an information retrieval device for retrieving image information by detecting retrieval information on an image recording medium such as a microfilm having image information and retrieval information for retrieving the image information. Regarding.

[Prior art]

In reader printers, etc., to search for image frames on microfilm, a mark is attached to the side of each image frame on the film with a different density than the surrounding area, and this mark is detected while the film is moving. There is a known method in which the film is counted by a counting section, and when the counted value matches the frame number of the desired image, the film is stopped, the desired image is retrieved, and this image is projected onto a screen for use. ing.

Incidentally, there are various kinds of films, and the recording position of the mark with respect to the image, the size of the mark, etc. are not constant.

FIG. 5 is a diagram showing the structure of a part of the roll-shaped microfilm, and shows four types of microfilms F and -F4. In the figure, frames with images recorded on the microfilm F1 are arranged in a row, and an opaque frame mark m1 is placed on the bottom of each frame. i': 1. The frame mark m1 is attached to each frame at a position where the distance between the left end (reference end) of the frame 1 and the left end (reference end) of the frame mark m is l.

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 I and the left edge of frame mark m2 is 12. ing.

On the microfilm F3, opaque marks ml and m3 are recorded on the upper and lower sides of each frame, and the frame mark m
, is attached to each frame, and the subject mark m3 is attached to the selected frame. The distance between the left edge of subject mark m 3 it' frame l and the left edge of subject mark m3 is! 3, and has a different length in the film advancing direction from the frame mark m.

On the microfilm F4, opaque marks ml and m3 are recorded on the upper side of each frame, the subject mark m3 is attached to the first frame of a series of frames whose image contents are related, and the frame mark m is attached to other frames. It is attached to the frame. There are various types of microfilm in addition to the examples.

As shown in Figure 5, the recording position, size, mark,
The types of filters and the like vary depending on the film, and when searching using such films, the user needs to input setting conditions corresponding to the film.

For example, information corresponding to the recording position of the mark (distance 11
r-j! g, 1a), information indicating the type of mark, information indicating whether the film is negative or positive, or whether the mark is transparent or opaque, etc. can be entered using a keyboard, etc. to keep the image stopped at a constant position or to accurately detect the image. I was trying to do it. 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 image stop position may shift and the image may not be projected at the correct position on the screen, causing part of the image to be missing when copying.
This will cause a problem in which images cannot be searched correctly.

Setting conditions for searching and copying corresponding to No. 1, control information for performing a search operation in standard mode, etc. are stored.

FIG. 4 is a flow diagram of the operation.

Next, the operation of this embodiment will be explained.

First, the cartridge 11 is installed at a predetermined position in the search section, but if the microfilm in the cartridge 11 is a standard mode film, there is no need to install a memory card. In this case, the memory card detector 40A notifies the control unit 43 that there is no memory card, so
The control unit 43 sets the search device to standard mode. The control unit 43 controls the search operation and the copy operation based on the information stored in the ROM 43A. On the other hand, cartridge 11
If the microfilm inside is not a standard mode microfilm, a memory card corresponding to the films F2 to F4 to be used is inserted into a predetermined card receiving section from the card insertion slot 16. When the memory card 17 is installed in a predetermined position, the card detector 40A detects the card 17, the reader 40B reads the information stored on the card, sends this information signal to the memory 43B of the control unit 43, and the memory 4
Store in 3B. The control unit 43 controls search operations and copy operations based on information signals stored in the memory 43B. Next, address information (for example, frame number) of the image information to be searched is inputted into the keyboard 15, and when a search start is commanded, the film is transported.

The control unit 43 detects a mark based on the standard mode information stored in the ROM 43A or the mark density information of the memory card stored in the memory 43B, either high level or low level of the signal output from the mark detector 14. Determine whether the signal should be counted by the counter. 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 section 43
determines which output signal from the mark detectors 14a and 14b should be sent to the counter based on the mark position information in the standard mode or the mark position information on the memory card stored in the memory 43A. For example, film F1
In the case of mark position information corresponding to ゜F3, only the output signal of the mark detector 14a is sent to the counter, and the
In the case of mark position information corresponding to
Only the output signal of is sent to the counter, and in the case of mark position information corresponding to film F3, mark detectors 14a and 14b are sent.
The output signals of the counters are controlled to be sent to respective counters.

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 43A of the control section 43 stores film stop data corresponding to the distance 11*12el13... between the reference edge of the frame and the reference edge of the mark, and the control section 43
OM43A standard mode stop position information or memory 43
Film stop data corresponding to the stop position information of the memory card stored in memory card B is read out from the ROM 43A, and the time from detecting a mark of a desired image to stopping the film is determined based on this stop data. In other words,
The image is stopped at a fixed position by changing the time from when a mark is detected until the brake is activated depending on the recording position of the mark relative to the frame. In addition,
The position correction data corresponding to the distance is stored in the ROM 43A, and the film is stopped immediately when the mark of the desired image is detected, and then the film is stopped using the position correction data in the standard mode or the stop position information stored in the memory card. The stop position of the image may be corrected by transporting the film in a predetermined direction by a set amount based on the corresponding position correction data.

Further, the control unit 43 is controlled to discriminate and count mark detection signals output from the mark detector 14 based on the standard mode mark form information stored in the ROM 43A or the mark form information stored in the memory card. For example, in the case of a memory card using film F3, the control unit 43
The mark detection signal output from the first mark detector 14a is counted by the first counting section based on the mark form information of the memory card stored in the memory 43B, and the mark detection signal is output from the second mark detector 14b. is controlled to be counted by the second counting section.

In the case of a memory card that uses film F4, the control unit 43 determines the frame mark m, frame mark m3, and frame mark m3 according to the pulse width of the mark detection signal based on the mark form information stored in this memory card, The mark detection signal of the frame mark is sent to the first counting section, and the mark detection signal of the subject 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 section 43 controls the blink portion P based on the standard mode or the image polarity information, density information, magnification information, etc. stored in the memory 43A.

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.

Next, when you finish using the cartridge 1, take it out from the cartridge receiving part, and take out the memory card 17 from the specified position, when you use another new cartridge, it is necessary to use a film that is not in the standard mode. Memory card 1 that corresponds to the film you are using
7, you can perform correct search operations.

That is, when a new cartridge is installed in the cartridge receiving section and a memory card corresponding to the film in the cartridge is installed in the card receiving section, the card detector 40A detects the memory card, and the reader 40B reads the information stored in the memory card. Read and go through the same steps as above,
A search for desired image information on the microfilm in the new cartridge can be performed. When no memory card is installed, the standard mode is set, so if a cartridge containing standard mode film is installed, a correct search can be performed in the standard mode. Note that if the memory card is not installed in the predetermined position or if the memory card is installed, the standard mode, the mode corresponding to the memory card, and the individual contents or specific contents of each mode are displayed on the display 42. The information may be displayed to inform the user of available film modes and the like.

Further, although the mode using film F is set as the standard mode, a mode using another film may be set as the standard mode.

The search information provided on the film is not limited to the marks used in the embodiment, but barcodes, 9-character numbers, etc. can also be used.

In addition, the image recording medium is not limited to microfilm.
Optical disks, magnetic disks, magnetic tapes, etc. can also be used.

In the above embodiment, the memory card is attached to and removed from the main body of the apparatus, but it may also be attached to and removed from the keyboard, or attached to the cartridge, and then attached to and removed from the apparatus body together with the cartridge.

〔effect〕

As described above, according to the present invention, there is no fear of making a mistake or forgetting an input operation, and it is possible to switch to a predetermined state simply by inserting a memory card, and as a result, desired information can always be retrieved correctly. This has the effect of making the operation extremely simple.
