Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a copying apparatus that searches for a desired frame in a film having a large number of frames in which images are recorded, and copies the image of this frame.

In recent years, with the increase in the amount of information, microfilms that record large numbers of images have become widely used. Microfilms come in various forms such as roll films and fish films. A large number of frames are arranged on microfilm.Generally, when photographing a large number of subject manuscripts on microfilm, one group of manuscripts with related information content is printed on pages in consecutive frames. 1 group (1 item) on microfilm
Images with related information content are recorded in sequential frame groups in page order.

For example, when photographing patent specifications on roll microfilm, one patent specification consisting of multiple pages is recorded as pages on multiple consecutive frames on the microfilm.
l. A plurality of frames recording one patent cut of this one case constitute one group of information whose information contents are related.

When such a microfilm is used as an original for copying and the recorded images on the film are to be copied, a copying device such as a microfilm reader printer or a microfilm printer is used.

Normally, when copying recorded images on microfilm using a copying machine, the film is first fed, the desired group of frames to be copied is searched for on the microfilm, and the first frame of the desired group is selected. Project it onto the screen, observe and confirm the content, and then move the first frame to exposure position C.
Then, the operator turns on the copy command switch by hand to command the start of copying, and after copying the first frame H, the film is fed. After completing the operation, operate the copy command Sui Sochi again,
Thereafter, it was necessary to repeat the above operation for the number of frames in one group.

Therefore, the operation is very troublesome and time-consuming for the operator, and is extremely inconvenient.

Generally speaking, copying machines eject the copy paper from the copy paper outlet with the image forming side facing upward so that the user can check the image on the copy paper.For this reason, one group of frames is Group f, the first one? , /l) are successively copied, and among the copies stacked one after another on the "joshashi" gutter tray, the four copies with the copy image corresponding to the last frame of the frame group of the l group are the best. Since it is on top, 4λ of the copy paper
However, the order was reversed, and the operator had to read the paper sheets 111 and align them 113 so that the pages were in the correct order after copying was completed, which was extremely inconvenient.

SUMMARY OF THE INVENTION An object of the present invention is to overcome the above-mentioned disadvantages by automatically obtaining a copy of 5rFvr, 1L, 1 group of information, and to produce a copy in which the pages are aligned in a predetermined correct order.

Still another object of the present invention is that the device malfunctions due to a jam of copy paper while copying group information, and after removing the jammed copy paper and resolving the malfunction, it issues a command to start copying again. To automatically obtain copies of a desired group without having to restart the copy from the beginning in the case of /ζ.

In the present invention, various forms of microfilm such as roll film and fish film can be used as the microfilm, and it goes without saying that the copying magnification includes various enlargement magnifications.

As shown in Figure 6, the microfilm F has an image recorded on each frame f on the film, and a frame mark m is attached to the side of the frame corresponding to each frame.
For each frame group of one group with related information content, an issue mark m2 is attached to the side of the frame corresponding to the previous frame of each group of frames, that is, the frame in which the image of the first page is recorded. There is. The frame mark and subject mark have different densities from the film haze part. The first one is placed in different columns on the film.

In Figure 6, frames A, ・A2, B+・B, ・B.

constitute one group of frames, each frame is marked with a frame mark m, and the first frame of the frame group of one group, that is, frames A, , B on the first page.

The item mark m is attached to the item. Note that one group of frames may be composed of only one frame instead of a plurality of frames, but it goes without saying that the present invention can also be applied to such information. In addition, the microfilm F is assumed to have its leading edge on the right side in Fig. 6, and is wound from the leading edge of the film by the winding wheel 99, and one image is imprinted on the film in page order from the leading edge of the film. .

-=r-" 100 of the detectors rt are comma marks m.

101 is a frame mark detector for detecting the mark m2, and 101 is a mark detector for detecting the mark m2, each of which has a photoelectric conversion element, and generates a high-level electrical mark detection signal when receiving an optical signal from the mark. do. Each mark detector is connected to an information retrieval device and a copy control circuit, which will be described later.

When the carrier holding stand 50 is at the home position, the image of the frame of the microfilm F on the film carrier 90 placed at a predetermined illumination position (projection position) corresponding to the condenser lens 40 is displayed on the screen 8 via the optical system. projected on.

FIG. 7 shows an information retrieval device, in which 1 (11 is the subject mark detector shown in FIG. 5, 1 ] (l is a counting circuit that counts the subject mark signals output from the subject mark detector 101, Reference numeral 111 is a comparison circuit that compares the current count value of the counting circuit 110 with the case number of the desired group input into the search number type capotan 12.

Consists of a subtraction circuit. 112 is a D/A converter, and 113 is a forward/reverse switch for switching the film feeding direction.

114 is a film drive motor, and the film feed roller 9
5.96 is connected to b.

Now, if the case number of the desired group to be searched that has been input into the search number input button 12 is A, and the number of b case marks (counted value) counted by the counting circuit 110 is 13, the subtraction circuit calculates A-B= Create C, determine the +/- of this C, and check its +/-
- Send a signal corresponding to a code and a numerical value to the forward/reverse switch 113 via the D/A converter 112. The output signal of the D/A converter 112 switches the forward/reverse switch 113 and outputs the signal to the drive motor 11.
4, the feed rollers 95 and 96 rotate to feed the film F, and when the calculated value of the subtraction circuit 111 becomes zero, that is, the input item number matches the count value of the counting circuit, and fccI : A high level match signal is output from the subtraction circuit 111, and this signal causes the motor 114 to stop.
Hufffilm stops.

Therefore, when the subject mark detector 101 detects the subject mark attached to the frames of the earlier application in the desired group of frames, the first frame is placed at a predetermined position illuminated by the lamp 39, and the film F is stopped. The image of the first frame is projected onto the screen 8 and can be read. At this time, the mark detector 100 is detecting the frame mark attached to the first frame.

1s2.153 is a delay circuit, and 154 is a copy production section.

When the copy making section 154 receives the output signal c of the delay circuit 153 (referred to as an exposure start signal), the forward clutch 71 is turned on as described above, and the various image forming means of the copy making section 1 described above are activated in a predetermined order. It operates to form a copy image of the microfilm on the copy paper S. G, o・Gl,・

It starts when you input it, and the Nyo Kafilm moves and the search is performed. When the search device 201 searches for desired information, it generates a high level match signal from the terminal 201, thereby stopping the film. , this coincidence signal causes a flip-flop FF. The value is set. Search device 201
The coincidence signal output from the terminal S is the subtraction circuit 1 in Fig. 7.
The calculated value of 11 will be obtained when the power I becomes zero. Note that the high level signal output from the terminal may be obtained when the case number is input to the search device.

As mentioned above, flip-flop FF. It is set when the power switch 10 is turned on, and is reset when the search device 201 completes the search. Therefore, the flip-flop FF. When in the key set state, the retrieval device stores information indicating that the search has been performed, and this stored information is erased when the power switch 10 is turned off to clear the device failure. In addition.

Flip-flop F
It is also possible to set F Io to clear the memory f14.

The film forward feeding device 150 is constructed as shown in FIG. Flip 70 Tsubu FF.

One input terminal a of is an AND gate G,. connected to,
The other input terminal is connected to an AND gate G, 1, and a flip-flop FF. The Q output terminal is connected to the delay circuit 300 and the forward drive circuit 30.
1 to the aforementioned film drive motor 114, and the Q output terminal is connected to a brake mechanism 302 for stopping the film feed rollers 95, 96. Therefore, the film advance device 150 operates to move the film forward when the AND gate G1 opens, and to stop the film when the AND gate G1 opens.

The output terminal C of the delay circuit 13100 is an AND gate G,1
It is connected to the. Delayed episode jli! 1300 is a flip 70 tube FF. When is set, a high level signal is output after a predetermined time delay of eight. The AND gate G+o opens when the copy command switch 11 is operated while the flip-flops Jl liN and o are in the reset state.
Also, when the film is being fed forward, G++ is opened when the mark detector 1fl1 detects the mark while the film is being fed forward.
Similarly, it is composed of a delay circuit, a reverse drive circuit, and a brake mechanism, and the delay circuit] 52 or the AND rate G1. The output of G14 operates the brake mechanism to stop the film.

When the film backward feeding device 151 is feeding the film backward, the output force 1. A high level signal is output from terminal -e.

Antogame) G opens when the frame mark detector 100 detects a frame mark while the film is being fed backwards.

It is assumed that mark detector 1(](1,1(11) generates a high-level mark signal when receiving an optical signal from a mark.

Next, the operation of searching for information on a desired group using the microfilm shown in FIG. 6 and obtaining copies of the frames of this group will be described.

First, when the power switch 10 is turned on, the setting circuit 200
The signal output from flip-flop FFho
is set. Next, when the case number of the desired group is input into the search number entry capotan 12, the detection device 201 is activated. The film is fed by the operation of the search device, and the information on the desired group of microfilm F and Oki is searched by the above-described operation. Now, if we set multiple frames B1, B, .B, as information of a desired group in Figure @6, and search for this information and copy it, the single mark detector 101 will detect the first one. When the mark m' of frame B of , , is detected, the film stops, and the image of the first frame B1 is automatically projected onto the screen 8. When the search operation of the search device #201 is completed, a high level signal is output from the terminal of the search device 201, and this signal sets the flip-flop FF.

stores that the detection operation has been performed.

After this, when the operator turns on the copy command unit 11 and commands the start of copying, the AND gate GIo opens,
The forward feeding device 150 is operated, and the film F is fed forward by the feeding rollers 95, 96 in the direction of arrow a (second direction) in FIG.

During the forward movement of the film, the single mark detector 101 detects the next mark of the desired group, that is, the first frame C1 of the next group closest to the last frame of the desired group.
When the subject mark m'l is detected, the AND gate GH is opened by the mark signal from this subject mark and the AND gate G1. The brake mechanism 302 is activated by the output signal to stop the film.

After a predetermined period of time has elapsed since the brake mechanism was activated (when the film F has come to a complete stop), a high level signal is output from the delay circuit 152, and this signal activates the film backward feeding device 151. As a result, the film F is moved by the feed rollers 95 and 96 in the opposite direction to that described above, that is, in the sixth direction.
It is sent backward in the direction indicated by the arrow in the figure (first direction).

On the other hand, the output signal of the delay circuit 152 sets the flip-flop F)i'', .During the backward feeding of the film F, the frame mark detector 100 is attached to the last frame of the desired group, and Frame mark, i.e. Frame B
, when the frame mark , is detected, the AND gate G14 opens, and the signal output from the AND gate activates the brake mechanism to stop the film.

After the brake mechanism is activated and a predetermined period of time has elapsed from C (the film F is completely stopped), a high-level signal is output from the delay circuit 153, and this low-level signal is sent to the copy making section 154 as an exposure start signal. Rare.

The copy making section 154 operates, and as described above, the carrier holding table 50 moves and a verification operation is performed for B3 placed at the illumination position.

When the copying of frame B8 is completed, the microswitch S shown in FIG. In addition,
This exposure end signal may be generated in conjunction with other operations of the copy making section (1) (preferably, it may be generated after the exposure operation is completed).

Flip 70 knob FF,, when the exposure end signal is output due to being in the set state, ant game) G,!
opens, and the output signal of this AND gate Gll+ causes
The film backward feeding device 151 is activated again. Frame B,
The copy sheet S on which the image has been copied is ejected to the ejection tray 6.

The film F is fed backward again by the operation of the film backward feeding device 151, and when the frame mark detector 100 detects the frame mark attached to the frame B on the film F, the film stops in the same way as described above, and the frame B, A copy operation is performed on the file. Frame B.

The copy paper S carrying the copy image is discharged to the discharge tray 6 and stacked on top of the previous copy paper.

After the copying of frame B is completed, the film F is fed backwards again in the same manner as described above, and when the frame mark detector 100 detects the frame mark of the first frame B, the film stops in the same manner as described above, and Copying operation is performed and frame B
The copy paper S carrying the copy image is discharged onto the discharge tray 6.

On the other hand, the frame mark detector 100 detects frame B at the beginning.

When the frame mark of frame B is detected, the single mark detector 101 detects the frame mark of frame B, frame mark m', and outputs a mark signal, and this signal opens the AND gate G, 3, which causes the flip-flop FF'++ is set. As a result, when the exposure end signal is generated from the copy making section 154 after the copying of frame B is completed, the AND gate G16 is opened and the frame B is copied.
A one-tube flop F r o is set. At this time, flip 70 knob F1. Since it is in the set state, even if the exposure end signal is output, the gate Gll+ is closed and no film advance or copying operation will be performed thereafter. The output signal of the computer game) G, , is sent as a copy completion signal to a display unit (not shown), and the display unit lights up to indicate that the copying of the desired group of frames has been completed. At this time, the lamp 39 may be turned on to project the image of the first frame B1 onto the screen, thereby notifying the completion of copying. Thereafter, the user searches for information on other groups using the search device in the same manner as described above, and when the copy command switch is operated after the search is completed, the copying operation of the frames of the desired group is automatically performed in the same manner. Therefore, the operator can automatically obtain a copy of the desired group of frames by simply operating the copy command Sui Sochi, and the pages of the copy will be aligned in the correct order, allowing the copy The work is simple and there is no need to align the pages after copying as in the conventional method, which is very convenient in practice.

It should be noted that, when the film is moved for information retrieval due to the operation of the retrieval device, the copying operation is not performed.

For example, the logic circuit may be set so that even if the copy command switch 11 is turned on in the middle of a search, G, , G, and 4 are closed.

In the above embodiment, during the copying operation for one group of information,
We have explained an example in which there was no failure in the device and the copying was performed smoothly, but now one group of frames B l.

When copying B, , B, frame B is copied during the third copy, that is, while copying the first frame B1.
A case will be described in which the copying paper on which . After turning off the power switch 10 and removing the jammed copy paper,
When the power switch 10 is turned on again, the flipflop FF and o are set, and the flipflop FF' is set.
The memory of lo is erased. Next, copy command switch 1
When turning on 1 to command the start of copying, the AND gate Ga
t is open (.

An exposure start signal is output from the delay circuit 153, and the copy making section 154 is activated again by this exposure start signal, and frame B is copied. Therefore, if you operate the copy command switch again after the fault is cleared, the frame that is currently in the position where it can be copied immediately, that is,
Copying is performed from frame B, which is placed at the copying position when the fault is cleared. When the copying of frame B is completed, the flip-flop F3. Since G is in the set state, G and G are opened, and the copying operation of the frames of the l group is completed. Therefore, even if a failure occurs in the apparatus during the copying operation for one group of frames.

The copying operation can be restarted from the frame at the time of failure.

Since the copying operation does not have to be repeated from the first frame, unnecessary copies are not made, which is practically effective.

FIG. 1O shows still another embodiment of the present invention, in which the power switch is turned off, the malfunction of the apparatus is removed, the power switch is turned on again, and the copy command switch is operated. In the embodiment shown in FIG. 10, the copying is redone starting from the frame that is currently at the position where it can be copied immediately.

The film is moved back one frame to the previously copied frame, and the copy is repeated from the previous frame.

A case in which the power switch 10 is turned off, the jammed copy paper is removed, the power switch 10 is turned on again, and then the copy command switch 11 is turned on will be described.

When the copy command switch 11 is turned on, the film forward feeding device l115o is operated, and the film is forwardly fed.

When the frame mark detector 100 detects the mark attached to frame B during forward movement, the flip 70 knob F F l

opens. ANDGATE G1. When the film is opened, the brake mechanism of the film backward transport device 151 is activated and the film is stopped.

On the other hand, ANDGATE G3. When the delay circuit 153 is opened, the delay circuit 153 is activated, and the copy production section 154 is activated by the internal light start signal outputted from the delay circuit 153.

A copying operation is performed for frame B.

Furthermore, the output signal of the delay circuit 153 resets the flip-flops F F and o.

Thereafter, the operation is similar to that described above, and when the copying of the image of the first frame B is completed, the AND gate G36 opens.

The copying of the frames of the predetermined group is completed. Therefore, even if the previously copied copy paper jams when starting copying the next frame, a copy without missing pages can be automatically obtained.

It is clear that the present invention can also be used with a film in which information is imprinted on the pages from the rear end of the microfilm, and in this case, the forward and backward feeding of the film will be reversed from the above embodiment. Dew.

As described above, according to the present invention, if a command to start copying is issued after a search is completed, the copying operation is started from the last frame, and if a command is issued to start copying after a fault is cleared, the frame is placed at the copying position when the fault is cleared. Since the copying operation starts from the frame that is currently in use, even if the device malfunctions due to a jam, it is possible to automatically obtain copies that are aligned with the pages, and there is no need to start copying from the beginning when the malfunction is cleared. This eliminates unnecessary copying. Furthermore, automation can save labor for the user. Further, a sorter for aligning the pages is not required, and the entire machine can be made smaller.
