Description

The present invention relates to an information retrieving device in a film handling device such as a film reader and the same reader / printer, and automatically retrieves the required information frame address by inputting the number of the required information frame by means of the information frame address designation input means. When executing the above procedure, the operation of the device is rationalized when the automatic search is executed by entering the information frame address that does not exist in the film currently used for the device by mistake. The purpose is to improve the operability for re-search and shorten the re-search time.

FIG. 1 is a perspective view showing a schematic configuration of a main part of an example of a microfilm reader or a reader printer.

In the figure, reference numeral 2 is a film cartridge inserted and set in the apparatus, and a roll microfilm 1 is wound around a reel and stored in the cartridge. 3 is a rotation driving motor for the reel in the cartridge (film rewinding motor), 6 is a film feeding roller (capstan roller) arranged near the film outlet portion 2a of the cartridge 2, and 5 is a rotation driving motor for the roller. 8 is a solenoid for vertically swinging the roller 6 and a roller support arm 9
Reference numeral 10 is a first and second film guide roller, 13 is a film winding reel, and 4 is a rotation drive motor (film winding motor) for the reel.

Reference numeral 12 denotes an automatic film winding mechanism for automatically winding the leading end leader tape 1a (Fig. 2A) on the leading end side of the microfilm, which has been conveyed by autoloading, around the core 13a of the film winding reel 13. The mechanism of this example has a shaft 12a.
An arcuate arm 12c having a small roller 12b pivotally supported at its tip end is freely swingable around the tip end of the arm 12 and a tension spring 12d is formed in a direction in which the tip end small roller 12b of the arm 12 is constantly pressed against the outer peripheral surface of the core 13a of the reel. Three pinch roller assemblies, which are biased to each other, are arranged on the outer periphery of the reel core 13a at substantially equal intervals.

Reference numeral 40 denotes a projection optical system arranged between the first and second film guide rollers 9 and 10, and includes an illumination lamp 14, a condenser lens 15, a film mark detector 11, a projection lens 16 and the like.

When the auto-loading button (not shown) is pressed after inserting and setting the film cartridge 2 into the device, the motors 5 and 4 are energized and the roller 6 is moved in the film feeding direction indicated by the arrow and the film is wound. The reel 13 is rotationally driven in the film winding direction. Further, the solenoid 7 is also energized and the roller support arm 8 is moved downward to move and hold the roller 6 in the film passage of the film outlet 2a of the cartridge 2. The lamp 14 is turned on.

The leading end of the leader tape 1a having a width wider than the distance between the pair of reel flanges is fed out by the nip portion between the film feeding roller 6 and the reel flange (not shown), and the rotational force of the roller 6 is generated by the rigidity of the leader tape 1a. Then, the first film guide roller 9 → the lower side of the mark detector 11 → the second film guide roller 10 → the film take-up reel 13 travels along the path to reach the core 13a of the film take-up reel 13. Then, the film leading end portion leader tape 1a is automatically wound around the outer peripheral surface of the core by the mechanism 12.

In addition, between the film feeding roller 6 and the first film guide roller 9, between the first and second film guide rollers 9 and 10.
Between the second film guide roller 10 and the film take-up reel 13, a guide plate forming a film traveling path is arranged, but these are omitted in the drawing.

The start of the film leader tape portion 1a by the film auto-loading is a black start which is inserted at the joint between the trailing end of the leader tape portion 1a and the leading end of the film 1 as the feeding and automatic winding of the leader tape portion 1a to the take-up reel core 13a progresses. The mark part MS (Fig. 2 (a)) is the mark detector 11
When it reaches the aperture portion 11d, its arrival is detected by the mark detecting element in the mark detector, and the motor 5 and the solenoid 7 are de-energized based on the detection signal to stop the rotation of the film feed roller 6. At the same time, the roller 6 moves upward from the surface of the film 1 and is held in a non-acting state with respect to the film 1. Further, the power supply to the motor 4 is cut off and the rotation of the film take-up reel 13 is stopped. That is, the film in the cartridge 2 is stopped in the standby state when the start mark portion MS is located at the aperture portion 11d of the mark detector 11 after the above-mentioned automatic loading and automatic winding on the take-up reel 13. Becomes

FIG. 2A is a schematic plan view in the middle of an example of the roll microfilm. There are various film frame search mark modes attached to the roll micro film. This example shows one of the so-called 3-level blip modes. In the figure, KB (1, 2 ...), KF (1, 2 ...), KP

It is a heading piece for large classification taken in front of each first file piece KF ₁ of KF (1, 2 ...). If you compare this to a book, you will see a batch piece KB (1.2
…) ・ File piece KF (1.2…) ・ Page piece KP (1.2)
…) Correspond to chapters, sections, and pages in husband and wife books. Reference numeral 1a denotes the above-mentioned leader tape portion at the leading end of the film, and 1b denotes the trailer tape portion at the trailing end of the film connected to the rear end portion of the film 1. The tape portion 1b is wound around the core of the reel in the cartridge. There is. ME is a black end mark portion which is interposed at a joint portion between the rear end portion of the film 1 and the tape portion 1b.

FIG. 3 is a partially cutaway enlarged perspective view of the mark detector 11. This example uses an optical fiber. 11
The mark detector case is a shallow rectangular box with an open top. Reference numeral 11b is a lid case that covers the main body case 11a. Reference numeral 11c denotes an aperture portion formed at a substantially central portion of the bottom plate of the main body case 11a so as to be larger than the film piece, and 11d denotes an aperture portion formed at a substantially central portion of a top surface of the lid case 11b and having substantially the same size as the film piece. The film 1 runs under the aperture portion 11c of the main body case 11a. 17a ・ 17b
Reference numeral 17c denotes three optical fibers. One end of each of these optical fibers is held by a holding member 11e arranged on the lower side of the aperture portion 11c of the case bottom plate in the main body case 11a, and the ends thereof are held. The parts are arranged facing downward along the lower side of the aperture part so as to be looked into the aperture. Thus, each mark MB formed by photographing the lower end face of the above three optical fibers 17a-17b / 17c to the lower image of the film 1
The lower images of MF / MP and start mark MS / end mark ME pass as film 1 runs. 18a ・ 18b ・ 18c
Are three phototransistors in which the other end faces of the three optical fibers 17a, 17b, and 17c are connected. The optical axis of the projection optical system 40 is the aperture part 11c of the bottom plate of the main body case.
And passes through substantially the center of the aperture 11d on the top surface of the lid case.

FIG. 4 is a perspective view of a key box 41 (or operation panel) as information frame address designation input means (input device), and numeral 19 is a ten-key pad 21 for inputting numbers such as batch file pages.
・ 22 is the batch key and file key to press when entering the batch number and file number with the numeric keypad 19, and 20 is the above numeric keypad 19 and batch key 21. A search key for starting the search after designating and inputting the required information frame address with the file key 22, 23 and 24 are one frame feed key ((+) key) and one frame return key ((-) key) of the film information frame respectively. , 25 are display devices for displaying the designated and input information frame address number, error, etc. 26 is a clear key.

Then, a desired film frame address is designated and input to the control circuit (search control circuit) by operating the key of the key box 41. Specifically, for example, if you want to search the file piece KP ₂ (Fig. 2 (b)) of 3 batches, 1 file, and 2nd page, enter "3" with the numeric keypad 19, press the batch key 21, and then Enter "1" and press the file key 22,
Then, "2" is registered. As a result, the address of the required film piece is designated and input. Further, the designated and input film frame address is displayed on the display 25.

If the search mode of the used film is the 2-level blip mode of file and page, the number of files is entered, the file key 22 is pressed, and then the number of pages is entered. -In the level blip mode, by inputting the number of pages (keys 21 and 22 are not used), the required frame addresses are designated and input respectively.

The piece address is designated and input as described above, and then the search key 20 is pressed. Then, as described above, automatic loading of the roll film 1 and automatic winding of the leader tape portion 1a of the film starting end portion on the core 13a of the take-up reel 13 are performed, and the start mark portion MS of the film 1 is changed to the aperture portion 11d of the mark detector 11. The film winding motor 4 of the apparatus positioned at the standby position is energized. As a result, the film take-up reel 13 is rotationally driven, and the film 1 on the cartridge lid 2 side travels to the take-up reel 13 side. As the film 1 travels, the marks on the lower side of the individual film frames become the three optical fibers of the mark detector 11.
Intermittent optical signals that sequentially pass under the downward end faces of 17a, 17b, and 17c and are incident on the optical fibers 17a, 17b, and 17c as they pass are incident on the phototransistors 18a, 18b, and 18c, and are electrically connected. Detection marks of individual film frames that are converted into signals and sequentially pass through the mark detector 11 section by the search control circuit including the microcomputer MB / MF / MP
Type detection, passage number counting, etc. are performed, and an automatic search for required information pieces is executed. The rotation of the take-up reel 13 is automatically stopped when the designated and input information piece of the specified information piece is positioned on the aperture portions 11c and 11d of the mark detector 11, whereby the still image of the required information piece is not shown by the projection lens 16. Is projected on the screen. In the case of a reader printer, when the copy button is pressed, the image of the information frame is projected on the photoconductor or the like to execute copying.

Each film piece search mark of film 1 MB (1.2 ...) ・
In the case of this example, the counts of MF (1.2 ...) and MP (1.2 ...) are counted sequentially from the first batch mark MB to 1 as the first MB ₁ for the batch mark MB, up to the last one in the film. Will be done. With respect to the file mark MF, the file mark MF (1, 2, ...) In the batch is sequentially counted as the first MF ₁ for each batch, and the count is reset every time the next batch is entered. For the page mark MP, the page mark MP (1.2
...) are sequentially counted with the first MP ₁ as 1, and the count is reset each time the next file is entered.

After the automatic search for one required information piece, the projection projection observation on the screen, or the copying is finished, the next required information piece address is set and input by the key operation of the key box 41, and the aperture parts 11c and 11d of the mark detector 11 are currently positioned. Whether the information piece of the address B set and input next based on the address A of the previously searched information piece located at the position is on the film take-up reel 13 side of the position of the mark detector 11 or the cartridge 2 It is judged by the control circuit whether it is on the side, the film take-up motor 4 or the rewinding motor 3 is rotationally driven, and the film 1 travels to the take-up reel 13 side or the cartridge 2 side. Similarly, an automatic search is executed,
The next required frame is located at the aperture parts 11c and 11d of the mark detector 11.

By the way, in such an information frame searching device, the register number of the address B of the required film frame to be searched is erroneously registered and the frame address B which does not exist in the film 1 set in the device is registered and noticed. If you start the automatic search with 20 search keys without it (hereinafter referred to as "register error search"),
Specifically, for example, as in the above example, 3 batches, 1 film,
When searching the file piece KP ₂ (Fig. 2 (b)) on the second page, the number "3" for the batch and the number "1" for the file were registered correctly when the number operation of the film piece address was performed. The page should be entered as "2", but the page number, such as "5", which does not exist in the 3 batches and 1 file is mistakenly entered, and then the search key 40 When the automatic search is started by pressing, the film 1 in the cartridge 2 is gradually wound up to the take-up reel 13 side without finding the address corresponding to the wrongly placed address in the case of the conventional device, and finally The end mark part ME of the film 1 is the mark detector 11
When the position is reached, the film running is stopped at that time, and an error warning is displayed on the display 25. The same applies when the batch or file numbers are misregistered.

So the operator noticed the number of misplacement of the piece address for the first time,
As a countermeasure, the error warning is released, the film 1 is moved, and the last piece of the film is positioned at the aperture parts 11c and 11d of the mark detector 11, and the address of this last piece is confirmed and the address is searched again. , The correct address of the required information frame, 3 batches, 1 file, 3 pages are input again, and the automatic search is executed again.

However, if the error warning is displayed only after the film 1 is wound up to the end mark portion ME, it wastes time and is not rational. In addition, there are many key operations from when the user notices an address number mistake on the error warning display until the automatic search is redone, which is troublesome and troublesome.

The present invention has been developed and proposed in view of the above, and the operation of the device in the case of a misregister search is rationalized to shorten the time for re-search and improve the operability. This type of information piece searching device is provided.

A specific example will be described below. FIG. 5 is a schematic diagram showing the input and output of the search control circuit. Reference numeral 27 is a search control circuit including a microcomputer. The input is a page mark signal 18a 'from the mark detector 11 file mark signal 18b' batch. Mark signal 18c 'and key box 41 numeric keypad 19, search key 20, batch key
These are key signals from the 21 key, 22 key, (+) key, 23 (-) key, and 24 clear key. Outputs include a display 25 and a film feed control circuit 28.

FIG. 6 is a block diagram showing an example of the search control circuit 27.

A counter 30 includes a page mark counter 30a for counting the page mark signal 18a ', a file mark counter 30b for counting the file mark signal 18b', and a batch mark signal 18b.
It has a batch mark counting unit 30c for counting c '.

When the film 1 travels in the direction in which the film 1 is wound on the take-up reel 13 (forward running), each mark counting unit adds and counts the input mark signals, and conversely runs in the direction in which it is rewound into the cartridge 2 (reverse running). At this time, the input mark signal is subtracted and counted.
Also, the page mark counting section 30a is reset when the mark detector 11 detects the file mark MF and the count value becomes "0" or "1", and the file mark counting section 30b
Is reset when the mark detector 11 detects the batch mark MB and becomes a count value "0".

Further, the search control circuit 27 stores each of the batch file page stored in the storage unit 31 and the input unit (key box) 41 which stores the address A of the frame searched before the search is started. It has a comparison circuit 32 for comparing the number and the count value of each counter of the counter 30. 34 is an OR gate. The storage unit 31 stores the value of each counting unit 30a, 30b, 30c of the counter 30 when the search key 20 is pressed, that is, the address A of the piece searched before the start of the search.

The comparison circuit 32 outputs a signal indicating the film feeding direction from the terminal a based on the comparison result, and corresponds to the number for each classification (batch file page) input to the input device 41 or stored in the storage unit 31. When the count value of the mark counting unit of the counter 30 matches, the film stop signal is output from the terminal b, and the input batch number and the count value of the batch mark counting unit or the input file number and the count value of the file mark counting unit are output. After any match occurs, when either of them does not match (judged to be an input number error), a signal is output from terminals c and d.

When the search is performed, the search can be performed either by traveling the film forward or backward, but the following description will be made assuming that the film is normally driven by the search start command to perform the search. In the case of traveling in the reverse direction, first, the piece with the batch mark of the piece group to which the desired piece belongs is searched, and then the film is normally moved to search for the desired piece.

FIG. 7 and FIG. 8 are operation flow charts of the film frame searching apparatus described above.

(A) In the case of normal search When the film frame address B which should not be searched is input to the search control circuit 27 by the key operation of the input device 41 (step 1) and the search key 20 is turned on (same 2), the film 1 runs normally. (Id. 3) is performed and the search is started. Along with this, the mark detection signals 18c ', 18b', and 18a 'of the batch file page are successively input from the mark detector 11 to the counter 30, and these mark detection signals are respectively added to the counting section of the counter 30. Counted at 30c, 30b, and 30a. Then, in the comparison circuit 32, each number of the batch file page input by the above-mentioned number and the batch mark counting section 30c counting the batch mark signal 18c ', the file mark counting section 30b counting the file mark signal 18b', and the page Mark signal 18
When the contents of the page mark counting section 30a counting a'are matched (steps 4, 6, and 8), a stop signal is output from the terminal b of the comparison circuit 32, and the film feed control circuit 28 causes the motor to be driven by the stop signal. 4 is stopped, and the normal traveling of the film is stopped (step 9). That is, the film piece at the specified address B designated and inputted is the aperture portion of the mark detector 11.
The rotation of the take-up reel 13 is automatically stopped at the time of being positioned at 11c and 11d, and the image of the film piece is enlarged and projected on a screen (not shown) by the optical system 40. Alternatively, copying is executed by pressing the copy button.

(B) In the case of searching for a numerical input error Specifically, as in the above-mentioned example, in order to search for the file piece KP ₂ in FIG. 2 (b), the correct piece address, 3 batches, 1 file, 2 pages, is entered. As an example, when you should enter the number, you miss the number of the page and enter the page number "5" that does not exist in the 3 batches / file and start the automatic search. In the process of the automatic search, the batch number entered by the number and the contents of the batch mark counting unit match first (steps 4 and 5), and the file number entered by the number and the contents of the file mark counting unit match. Yes (steps 6 and 7). Then, when the page marks MP in 3 batches and 1 file are sequentially counted and the last page mark MP ₃ in the file is counted, the next file mark MF ₂ is counted (step 20). While the count of the page mark counting section 30a is reset, the file mark counting section 30b and the contents of the file number input by the numerical register do not match (step 7).

Therefore, the file mark counting unit
An error signal is output from the terminal c of the comparison circuit 32 when 30b counts the signal of the next file mark KF ₂ .
This error signal causes the film feeding control circuit 28
Stops motor 4. That is, the normal running of the film is
The mark detector 11 stops with the corresponding file piece KF ₂ of the file mark MF ₂ positioned on the aperture portions 11c and 11d (step 11).

Further, when an error signal is output from the terminal c, a warning signal is output from the terminal d, the display 25 blinks by this signal, and the operator is warned of the error (step 12). This warning may be made by displaying an error mark or character display on the display, making a sound such as a buzzer, or turning on a warning lamp. This error warning will continue unless any key in the keybox is turned on.

Further, when an error signal is output from the terminal c, the stored value of the storage unit 31 (address A of the frame searched before the start of the search) is transferred to the comparison circuit 32 (step 13). The comparison circuit 32 compares the transferred storage value A with the contents of the counter 30, and based on the comparison result, sends the film in the direction in which the frame of the address A stored in the storage unit 31 is searched. The film feed signal is output from the terminal a. The feed signal causes the film feed control circuit 28 to drive the motor 3 or the motor 4 to feed the film in a predetermined direction (step 14). Then, in the comparison circuit 32, the transferred stored value A, that is, each number of the batch file page of the frame searched before the search is started and each counting section 30a, 30b, 30
When the contents of c match each other (steps 15 to 17), a stop signal is output from the terminal b of the comparison circuit 32, the signal stops the motor, and the film stops running (step 9). The original piece that was searched before you made a mistake is automatically searched. After that, the correct piece address of the required piece is re-entered in the input device 41 and the search key 20 is pressed to automatically search for the piece of the re-entered correct piece. In that case, the key operation is simple, and the re-search time is shortened and the operability is improved in the case of making a misregistration as compared with the conventional device.

The above example is for the case where the page number is entered incorrectly (misregistration), but when the file number is entered incorrectly, the next higher mark, that is, the batch mark, is counted (step 21). Since the input batch number and the batch mark counting section do not match, it is determined that there is a misregistration, and the operation flow from step 5 to steps 11 to 17 and 9 is entered as in the case described above.

Steps 4 ', 5', 6 ', 7', 15 ', 16' indicate the steps of feeding and running the film.

As described above, in the apparatus of the present invention, the film 1 is the end mark portion of the film as in the conventional apparatus even if the number registration error search is performed.
The film winding number is not wound up to ME, and the film winding is automatically stopped halfway when the next file mark or batch mark is counted. Therefore, there is no time loss when the film 1 is wound up to the terminal end.

Then, after returning to the state before the search is started, it is possible to execute the re-search with the correct frame address again. In that case, the key operation is simpler and the re-search when the numerical entry error search is performed compared to the conventional device. Time is shortened and operability is improved.
