Abstract

PURPOSE:To improve the operability for re-retrieval of the device when the automatic retrieval is executed while giving entry of information frame address and to shorten the re-retrieval time by using a feeding control means rewinding a photo film until the 1st mark is detected. CONSTITUTION:When an error signal comes out of a terminal (b), an alarm signal is outputted from a terminal (c), a display device 25 is flickered by this signal so as to raise alarm of error to the operator. When a signal ''1'' is outputted from an output Q of an FF31, a transistor 34 is conducted and a film 1-frame back drive circuit 29. Then the film 1 is reversed for one frame's share and when a mark detector 11 detects a page mark, the film is stopped. Then the error alarm is released by inputting again correct frame address of the required film frame newly by an input device 41 after that. The re-input address is displayed on a display device 25 and also the automatic retrieval of the film frame of the correct address subject to re-input is executed.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an information retrieval device in a microfilm handling device such as a microfilm reader or rotary printer. What should the device do when an automatic search is executed by entering an information frame address that does not exist in the microfilm currently inserted into the device? The purpose is to improve the operability of the re-search process and shorten the re-search time by making it more reasonable.

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

In the figure, reference numeral 2 denotes a film cartridge inserted into the apparatus, and a roll microfilm 1 is wound onto a reel and stored in the cartridge. 3 is a rotation drive motor (film rewind motor) for the reel in the cartridge, 6 is a film feed roller (gear bus tan roller) disposed near the film exit portion 2a of the cartridge 2, and 5 is a rotation drive motor for the roller. - ta, 7 and 8 are solenoids and roller support arms for vertically swinging the roller 6; 9 and 1O are first and second film guide rollers;
13 is a film take-up reel, and 4 is a rotation drive motor (film take-up motor) for the reel.

Reference numeral 12 denotes a film automatic winding mechanism that automatically winds the leader tape la (FIG. 2 (a)) on the leading edge side of the microfilm transported by autoloading around the core 13a of the film winding reel 13. . The mechanism in this example is free to swing around a shaft 12a, and has a small roller 12b at its tip.
A pinch roller assembly is made up of an arcuate arm 120 which is supported by a pivot, and is biased by a tension spring 12d in a direction in which a small roller 12b at the tip of the arm 12 is always pressed into contact with the outer peripheral surface of the core 13a of the reel. Three sets are arranged at approximately equal intervals around the outer periphery of the reel core 13a.

A projection optical system 40 is disposed 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.

After inserting and setting the film cartridge 2 into the device, when the autoloading button (not shown) is pressed by Δ, the motors 5 and 4 are energized and the row 26 moves in the film feeding direction as shown by the arrow, and the film is wound up. The reel 13 is driven to rotate in the film winding direction. Also, the solenoid 7 is energized, the roller support arm 8 moves downward, and the roller 6 is moved and held in the film path of the film exit portion 2a of the cartridge 2. The lamp 14 is turned on.

The leading end of the leader tape 1a, which has a width wider than the distance between the pair of reel flanges, is fed out by the nip between the film feed roller 6 and the reel flange (not shown), and is fed out by the nip between the film feed roller 6 and the reel flange (not shown), and is fed out of the row 26 depending on the stiffness of the leader tape 1a. Due to the rotational force, the first film guide roller 9 → mark detector 1
The film travels along the lower side of 1 → the second film guide roller 0 → the film take-up reel 13, and reaches the core 13a of the film take-up reel 13. However, the mechanism 12 automatically enters the winding state.

In addition, between the film feeding row 26 and the first film guide roller 9, the first and second film guide rollers 9 and 1
A guide plate forming a film running path is provided between the second film guide row 210 and the film take-up reel 13, but it is not shown in the figure.

The feeding and automatic winding of the leader tape section 1a at the starting end of the film to the winding series reel core 13a by the above-mentioned film autoloading progresses, and the leader tape section 1
When the black start mark part MS (Fig. 2 (a)) interposed at the joint between the rear end of a and the front end of the film reaches the aperture part lid of the mark detector 11, the arrival is determined to be The mark is detected by the mark detection element in the mark detector, and the motor 5 and solenoid 7 are activated based on the detection signal.
When the current is cut off, the rotation of the film feed roller 6 is stopped, and the roller 6 escapes upward from the surface of the film 1 and is held in a non-acting state with respect to the film 1. Also, the power to the motor 4 is cut off, and the film take-up reel 130
Rotation is stopped. That is, the film in the cartridge 2 is not automatically loaded and automatically wound onto the take-up reel 13, and when the start mark part MS is located at the aperture part lid of the mark detector 11, the film stops running and waits. state.

FIG. 2(a) is a partially omitted plan view of an example of a roll microfilm. There are various film frame search mark modes that can be added to roll microfilm. This example shows one of them, the so-called 3-level grip mode. In the figure, ・KB(, ・2...)・KF(1・

This is the aperture section. Aperture part 11c of film 1rrz main body case lla
Runs in the lower part of the country. 17a@17bII17c are three optical fibers, and one end of these optical fibers is inserted into the aperture part 11c of the cane bottom plate in the main body case lla.
They are held by a holding part side located on the lower side of the holder, and are arranged with their ends facing downward and looking into the aperture along the lower side of the aperture. Each mark M is formed by photographing the lower end surfaces of the three optical fibers 17a, 17b, and 1.7c onto the lower edge of the film 1.
13. The lower edge of MP@MP and the start mark M8 and the end mark PJE pass as the film 1 runs. 18a, 18b, and 18c are the above three optical fibers 1
These are three phototransistors whose respective other end surfaces of 7a, 17b, and 17C are connected. The optical axis of the projection optical system 40 passes through the approximate center of the aperture portion 11c of the bottom plate of the case and the aperture portion lid of the top surface of the lid case.

FIG. 4 is a perspective view of a key box 41 (or operation panel) as an information piece address designation input means (input device);
is the numeric keypad used to enter batch, file, page, etc. numbers, 21 and 22 are the batch and file keys that are pressed when entering batch numbers and file numbers using the numeric keypad 19, respectively, and 20 is the upper keypad 19, batch key 21, and file keys. Key 22 is used to specify and input the required information frame address, and the search key starts post-checking. 23 and 24 are the 1-frame advance key ((l-) key) and 1-frame return key (←) key for film information frames, respectively. ), 25 is a display device that displays the specified input information frame address number, errors, etc. 26 is clear gear.

Then, by operating the keys on the key box 41, a desired film frame address is designated and input into the control circuit (search control circuit). Specifically, if you want to search for 3 batches, 1 file, and 2nd batch film frame KP2 (Fig. 2 (0)), enter "3" on the numeric keypad 19 and press the batch key 21. , then enter "1J and enter file key 2.
Press 2, then enter [2]. As a result, the address of the required film frame is designated and input.

Further, the designated input film frame address is displayed on the display 25.

If the search mode for the film to be used is the 2-level grip mode of file and page, enter the number of files and press the file key 22, then enter the number of pages, and the 1-level In the case of the grip mode, the required frame addresses are designated and inputted by entering the page number (keys 21 and 22 are not used).

The frame address is designated and input as described above, and then the search key 20 is pressed. Then, as mentioned above, the autoloading knob of the roll film 1, the core 13 of the take-up reel 13,
The film start end leader tape section 1a is automatically wound around the start mark section MSff of the film 1.
The i-mer is energized. As a result, the film take-up reel 13 is driven to rotate, and the film 1 on the cartridge 2 side travels toward the take-up reel 13 side. As the film 1 travels, the marks on the lower side of each film frame are exposed to the three optical fibers 17a and 17b of the mark detector 11.
- Intermittent optical signals passing under the downward end face of 17C and incident on the respective fibers 17a, 17b and 17C as they pass through the phototransistors 18a and 18
b.The light enters 18C and is converted into an electric signal, and passes through the mark detector 11 section sequentially by the micro-convenience controller (tr) search control circuit.f.Detection of a fixed film frame.Detection of the type of mark MB-MF/MP. , the number of passes is counted, and an automatic search for the required information piece is executed. Then, the information piece of the designated and inputted location is detected by the mark detector 11.
When the take-up reel 130 is located at the aperture portion 11C/lid, the rotation of the take-up reel 130 is automatically stopped, and a still image of the required information frame is enlarged and projected onto a screen (not shown) by the projection lens 16. In the case of a reader printer, by pressing the object button, the image of the information frame is projected onto a photoreceptor or the like, and the object is photographed.

Each film frame search mark MB (I.

Force 2...) "FCl 2...)" P(1 2) count is the Nocturnal mark M in this example, as will be described later.
As for B, the first one, MB, is counted as 1, and the numbers are sequentially counted up to the last one of the film.

Regarding file mark MF, for each batch, the file mark MF (1-2-) in the batch is counted as 1, with the first MF being 1, and the count is reset every time it enters the next batch. .Also, regarding page mark MP, in-file page mark MP (1'
2. ) are counted sequentially with the first one MP, as 1,
The count is reset each time the next file is entered.

After completing the automatic search for one required information piece, enlarged projection observation on the screen, or photographing, set and input the address of the next required information piece using the key operation of the key box 41. Search for the next located information frame Set the above information frame based on the address of the adjacent information frame Is the information frame at the next manually entered address located closer to the film winding reel 13 than the position of the mark detector 11 or closer to the cartridge 2? The control circuit determines whether the film is rewinding, and the film winding motor 4 or the rewinding motor 3 is driven to rotate, and the film 1 travels on the take-up reel 13 side or the cartridge 2 side, and the above-mentioned optical information frame is rotated. In this case, an automatic search is similarly performed, and the next required piece is located in the aperture section 11C/lld of the mark detector 11.

By the way, in such an information frame search device, the address number of the required film frame to be searched is incorrectly set, and a frame address that does not exist in film 1 set in the device is set, and the search key is pressed without paying attention to it. When you press 20 to start an automatic search (hereinafter referred to as a numeric error search), specifically, for example, 3 batches, 1 file, 2nd page file piece Kid (see Figure 2). (b)) When searching for the film frame address, [3] for the bunch and [1] for the file were set correctly, but for the page, it should be set as ``1-2''. However, if you accidentally enter a page number that does not exist in the 3 batches/1 file, for example, "5", and then press the search key 40 to start an automatic search without noticing the 1st number mistake. In the case of the conventional device, the film 1 in the cartridge 2 is gradually wound toward the take-up reel 13 without finding the location corresponding to the location of the misplacement number, and finally the end mark i13MB of the film 1 is When the film reaches the position of the mark detector 11, the film travel is stopped and an error warning is displayed on the display 25. The same thing happens if you misplace the bunch or file number.

For the first time, the operator noticed the number of incorrect piece addresses.
As a countermeasure, cancel the error warning, move the film J and mark the aperture section 11C of the detector 11.
Place the last frame of the film in this position, check the address of this last frame, enter that address as the reference address for the rich search, and then enter the correct address of the required information frame in 3 batches, l file, and 3 pages. After re-entering the key, the automatic search is executed again.

However, if the error warning is displayed only after the film 1 is wound at the end mark MEJ, time is wasted and it is not rational. Furthermore, the process from noticing a mistake in address number when an error warning is displayed to automatically searching and correcting the address requires many key operations, which is time-consuming and troublesome.

The present invention has been developed and proposed in view of the above, and is a practical application that streamlines the operation of the device in the case of misplaced searches, reduces the time required for searching again, and improves operability. The purpose of this invention is to provide this kind of information verification device.

This will be explained below using a specific example. 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, and the input is the page mark signal 18 from the mark detector 11.
a', file mark signal 18b', batch mark signal 18C, and the keys of the key box 41 including the numeric keypad 19, search key 20, bunch key 21, file key 22, (+l key 23, (-1 key 24, clear key 26) The outputs include a display 25, a film feed/stop control circuit 28, and a one-frame back drive circuit 29.

FIG. 6 is a block diagram showing an example of the inspection control circuit 27. 30 is a counter and the page mark signal 18
A page mark counting section 30a that counts a''k, a file mark counting section 30 that counts the 7-aisle mark signal 18b'
It has a bunch mark counting section 30c that counts b and bunch mark signals 18C'. Each mark counting part is film 1
travels in the direction in which it is wound up by the winding reel 13 (forward travel)
When the cartridge 2 is rewound, the input mark signal is added and counted, and when the cartridge 2 is rewound (reverse travel), the input mark signal is subtracted and counted. Also, the page mark counting section 3
0a is reset when the mark detector 11 detects a file mark MF and the count value is not "0" or [1], and the file mark counting section 30b is reset when the mark detector 11 detects a batch mark MB. It is reset and the count value becomes rOJ.

Furthermore, inside the search control circuit 27, there is an input device (
There is a comparison circuit 27' that compares each batch file page number input into the key box 41 with the count value of each counting section of the counter 30. 31 is a flip-flop circuit, 32 and 33 are OR gates, and 34 and 35 are transistors.

The comparison circuit 27' stores a counter 3 corresponding to the number for each classification (bunch file page) input to the input device 41.
When the counted values of the 0 mark counting section match, a film stop signal is output from terminal a, and the input batch number and the counted value of the punch mark counting section or the input file number and the counted value of the file mark counting section match. After that, when any one of them does not match (it is determined that there is a mistake in the input number), a signal is output from terminals S and C.

When performing a search, it is possible to perform a search by running the film forward or backward; however, the following description will be made assuming that the search is performed by running the film forward in response to a search start command. When traveling in reverse, the film is first searched for the punched frame in the frame group to which the desired frame belongs, and then the film is moved forward to search for the desired frame.

FIG. 7 is an operational flow diagram of the film frame retrieval device described above.

(a) In the case of normal search When the film frame address to be searched is input to the inspection control circuit 27 by key operation of the input device 41 (step 1) and the search key 2o is turned on (step 2), film 1 is moved forward (step 1). 3) is performed and the search is started. Along with this, each mark detection signal 180', 18b', 18a' of the batch file page is input from the mark detector 11 to the counter 30 one after another, and each of these mark detection signals is input to the counter 30, respectively. It is counted as 30C, 30b, and 30a. Then, in the comparison circuit 27', the batch mark counting section 30 counts each batch file page number inputted above and the batch mark signal 18C'.
C. When the contents of the batch mark counter 30b that counted the file mark signal 118b' and the page mark counter 30H that counted the page mark number 18a' match (steps 4 to 8), the terminal of the comparison circuit 27' A stop signal is output from a, the stop signal activates the second register 35, and the film feed/stop control circuit 28
is activated and the film stops running (step 9). That is, when the film frame at the designated I9r standard location is located at the aperture portion 11C/lid of the mark detector 11, the rotation of the take-up reel 13 is automatically stopped, and the image of the film frame is displayed on a screen (not shown) by the optical system 40. ) is enlarged and projected. Alternatively, the subject is executed by pressing the subject button.

(b) In the case of misplacement search Specifically, as in the example above, in order to search for film frame KP2 in Figure 2 (b), the correct frame address is 3 bunches, 1 file, 2 pages, For example, when you should have entered the page number, you made a mistake in the page number and entered the page number "5", which does not exist in the 3 bunches/1 file, to start an automatic search. In this case, in the process of automatic search (C), first, the entered punch number matches the contents of the hit mark number section (steps 4 and 5), and then the entered file company name and the contents of the file mark counter match (steps 4 and 5). Match (steps °6 and 7). When the last page mark MP in the file is counted and the last page mark MP in the file is counted, the next file mark MF2 is counted. The count in the file mark counter 30a is reset, and the contents of the file mark counting section 30b and the input file number no longer match (step 10).

As a result, it is determined that a numbering error has occurred, and when the file mark counting section 30b counts the signal of the file mark MF2 according to the above method, an error signal is output from the terminal of the comparator circuit 27', and this error signal causes the shifting flip-flop Pu 31
is set. At this time, the signal rlJ is outputted from the output Q, and the transistor 35 is made conductive via the orate 33, and the film feed/stop control circuit 28 is activated, so that the film travels at the aperture portion i of the mark detector 11.
Stops with file frame KF2 corresponding to file mark ■F2 positioned on 1c/lid (step 11)
.

Also, when the terminal number 2 is output from the terminal C, a number signal is output from the terminal C, and in response to this signal, the display 25 flashes to warn the operator of an error (step 12). This warning causes an error mark or text to be displayed on the display, generates a sound such as a buzzer, or lights up a warning lamp, but continues until it is turned on. Also clip front 31
When the signal [1] is output from the output Q, the transistor 34 becomes conductive and the film one frame bank drive circuit 29 operates (step 13).

As a result, the film 1 is moved backward by one frame, and when the mark detector 11 detects the page mark MP3, the film stops. In other words, the mark 1.7 is placed on the aperture section 11c/lid of the output device 11, and the frame immediately before the file frame KF2.
That is, 3 bunches, 1 file, 3 pages of film frame KP.
The film stops when 3 is positioned (step 14).
9).

Thereafter, by re-entering the correct frame address of the desired film frame on the input device 41 and pressing the search key 20, the error reporting power is removed, and the re-entered address is displayed on the display 25.
will be displayed, and an automatic search will be executed for the film frame at the correct address that was re-entered. By the way, press the – key to
The desired film frame may be found by moving the film backwards one frame at a time.

The above example is for the case where the page number is entered incorrectly (numbering error), but if the file number is entered incorrectly, when the next higher mark, that is, the batch mark is counted, the manual batch number And the batch mark counting section will be inconsistent, so this is it! It is determined that there is an error in the Ill setting, and the operation flow from Step 17 to Steps 11 to 14.9 starts as in the case described above.

As described above, even if the apparatus of the present invention performs a positioning error detection, unlike the conventional apparatus, the film 1 is not wound at the end mark ME-E of the film end, and the film mark or bunch mark next to the film frame address where the positioning error has been made does not occur. When the number is counted, film winding is automatically stopped midway, and an error warning is issued, which makes it possible to realize that the number has been set incorrectly. Therefore, there is no time loss in winding up the film 1 to the end.

When the film is stopped halfway, it is possible to perform a re-search using the correct frame address.The key operation in this case is simple, and unlike conventional devices, it is possible to perform a re-search using the correct frame address. Time is shortened and operability is improved.
