Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a copying method for automatically obtaining a copy of a desired information frame in a microfilm having a large number of information frames.

In recent years, with the increase in the number of information departments, microfilm, which records a large amount of information in a reduced form, has become widely used.There are various forms of microfilm such as roll film and fish film, and A large number of information frames are arranged in parallel on the microfilm.Normally, when photographing a large number of subject manuscripts on microfilm, one document (one unit) with related information content is placed in a series of frames on the microfilm. They are photographed in order. Therefore, on the microfilm, information frames with related information contents are consecutively arranged at regular intervals.

For example, when photographing patent specifications on roll microfilm, each patent specification has 1 page as 1 frame, and the number of frames corresponds to the number of pages in 1 document. The information pieces are recorded in order from the beginning, and this one piece of information piece material becomes one piece (one unit) of information related to the information content.

When copying information recorded on such microfilm, a copying device such as a microfilm reader printer or a microfilm printer having an information retrieval device is used.

When copying each frame of a desired item on a microfilm using a copying machine equipped with an information retrieval device, first, copy the information at the beginning of the information frame material for the 9 items on the microfilm that require copying (first page). ) and select the desired piece 1. After searching for the first frame, move the first frame to the copy position (print position)
The operator then operates the copy button to copy the first frame. After copying the first frame, the operator feeds the microfilm and places the next (second page) frame at the copying position. , then operate the copy button to copy the next piece, and then
]-, By repeating the operations for one frame, copies of each frame of the desired frame are obtained.

In this method, the operator must feed the microfilm frame by frame, position the frame at the copying position, and operate the copy button, making the copying process very troublesome and time-consuming. It was extremely inconvenient.

Additionally, in general, in copying machines, copy paper is ejected to the copy paper ejection tray with the copy image forming side oriented "-" (so that the operator can immediately observe the condition of the copy image on the copy paper). and are stacked in E in the order of discharge,
When you start copying the desired information from the first frame, the copy sheets stacked one after another on the copy paper output tray are those with the copy image of the last page of the desired information piece material. come. As a result, the stacking order of the copy sheets is reversed, and the operator has to rearrange the stacking order of the copy sheets from "-" to the page order after copying is completed, which is very inconvenient. A collating machine can be used to automatically arrange the pages in order, but this has the disadvantage that the equipment is expensive.

The purpose of the present invention is to completely eliminate the drawbacks of writing, and to make it possible to automatically start copying information on a desired item from the frame of the last page by simply performing a copy command operation once. It is in.

In the present invention, various forms of film such as roll film and fish film can be used, and copying can be performed at various copying magnifications.

For example, a search number entry capo 12 for inputting a case number and a copy number setting dial 13 for setting the number of copies of information to be copied are provided.

As shown in FIG. 2, the printing unit 1 has a photosensitive drum 15 in which a transparent insulating layer is formed on the photoconductive photosensitive layer, and the photosensitive drum 15 rotates at a constant speed in the direction of the arrow. The microfilm is permanently charged by a charger 16, and then when it reaches an exposure section 17 onto which an image of the microfilm is projected, the image is subjected to slit exposure and at the same time is AC charged by an AC charger 18. Then, the entire surface is exposed by an overall exposure lamp 19 to form an electrostatic latent image on the drum surface.
The latent image is visualized by the developing device 20. Next, the excess developer in the tram is squeezed out by the negative charger 21 without disturbing the image. Next, a sheet of copy paper (transfer paper) S fed from the cassette 5 is brought into close contact with the photosensitive drum 15 by the paper feed rollers 22, 23, 24, and a visible image on the drum 15 is charged by the transfer charger 25. is transferred onto copy paper S''-. After the transfer, the copy paper S is transferred to the drum 15 by the separation belt 26.

Note that the paper feed roller 22 is constantly rotating, and the drum 15
When the paper reaches a predetermined position, it descends in response to a signal generated and comes into contact with the secondmost sheet of copy paper S in the cassette 5, and after feeding one copy paper from the cassette, it is lifted up again. ,
Subsequent paper feeding is performed by timing rollers 23 and 24.

In the drying and fixing section 27, the copy paper S is placed on a heated hot plate 2.
9, the back side is brought into close contact with the paper, and the paper is dried and fixed. The dry and fixed copy paper S is discharged to the discharge tray 6 via discharge rollers 30 and 31.

The observation section 2 has a projection lens 34, mirrors 35, 36, 37, and a half mirror 38 as shown in FIG. Illuminated by the lens 40, the image of the illuminated microfilm frame passes through the projection lens 34 as shown by optical path a, and is reflected by the mirrors 35, 36.
After passing through °37, the entire image is enlarged and projected onto the screen 8.
Alternatively, as shown above, the optical path passes through the projection lens 34, passes through the mirror 35, the half mirror 38, the narrow mirror 41, and the shutter (not shown), and a part of the image is enlarged and projected onto the photosensitive drum 15 in the form of a slit. Note that a known total reflection mirror may be inserted into and taken out of the optical path instead of the half mirror.
A movable member 47,48 is movably arranged at 5°46. The movable members 47, 48 fixedly support the carrier holder 50, and reciprocate along the rails 47, 48 together with the carrier holder 50 by a drive mechanism to be described later. As shown in FIG. 4, the carrier holding table 50 has a long hole 51 and a rectangular light guide hole 52 provided at a position corresponding to the condenser lens 40 in the machine box 4. 53 is a screw hole for fixing a microfilm carrier, which will be described later.

In FIG. 4, the driving force of a motor 60 driven at a constant speed is transmitted to a reduction sprocket gear 62 via a reduction mechanism 61, and an endless chain 68 is connected between this reduction sprocket gear 62 and other sprocket gears 63 to 67. It has been passed. Sprocket gears 65 and 66 are each rotatably supported by a rotating shaft, one sprocket gear 65 is coupled to the rotating shaft via a reverse clutch 70, and the other sprocket gear 66 is coupled via a forward clutch 1. When the clutch 70.71 is turned on, the corresponding sprocket gear 65.66 and the rotation shaft are drivingly connected, and when the clutch 70.71 is turned off, each sprocket gear 65.66 is connected to the rotation shaft. rotates freely about the rotation axis. Sprocket gears 72 and 73 are located at the ends of the rotating shafts of each sprocket gear 65 and 66, respectively.

It is fixed to pins 80.81 of member 47. The wire 79 is wound so as to reciprocate around the movable members 47 and 48 in accordance with the direction of rotation of the small gear 75. Either one of the clutches 70 and 71 is selectively activated, and the forward clutch 71 is activated in response to a copy command signal, which will be described later.
When the sprocket is turned on, the gear 66 and its rotating shaft are connected, the small gear 75 and the large gear 76 rotate, and the carrier holding table 50 moves forward by the wire 79. On the other hand, when the reverse cruncher 0 is turned on by a copy command signal, which will be described later, the sprocket gear 65 and its rotating shaft are connected, and the rotating shaft of the sprocket gear 66 is rotated via the chain 74, and the small gear 75 and the large gear 76 are connected to each other. , the carrier holding table 5o is moved back and forth by the wire 79. When both clutches 70, 71 are off, the rotating shafts of the sprockets 65, 66 do not rotate, and therefore the gears 75, 76 do not rotate, so the carrier holding table 50 stops.

The drum driving sprocket gear 67 is coupled to an intermediate gear 83, and the intermediate gear 83 is a gear 8 integrated with the photosensitive drum 15.
4 and 1 are cocooned together. Therefore, when the chain 68 is driven, the photosensitive drum 15 rotates at a constant speed in the direction of the arrow IJC.

Switch S located in part -1 of machine box 4, ,
S is for detecting the position of the carrier holding stand 50, and when the microswitch Sl detects the carrier holding stand 50, the carrier holding stand 50 is at the home position, and the carrier holding stand 50 is at the home position. At this time, the microfilm image is projected onto a screen and can be viewed.

When a print signal, which will be described later, is sent to the forward clutch 71, the carrier holding table 50 moves forward from this home position and starts copying the microfilm, and when the copying operation is finished, the micro switch 32 moves the carrier holding table 5.
0 is detected, a copy end signal is output from the microswitch S2, and this signal turns on the reverse clutch 70, thereby causing the carrier holding table 50 to move backward. When the microswitch S detects the carrier holding stand 50, the reverse clutch 70 is turned off and the carrier holding stand 50 stops at the home position.

FIG. 5 shows a microfilm carrier fixedly held on the carrier holding stand 50, and the microfilm carrier 90 is connected to the long hole 51 and the screw hole
The carrier 90 has openings 91 and screw holes 92 at positions corresponding to the carriers 90 and 2, respectively, and the carrier 90 is fixed to the carrier holding base 50 with screws.

Furthermore, the film carrier 90 includes a fixed plate 94 for positioning the film magazine 93, and a film feed roller 95.9.
6. It has film guide rollers 97 and 98, and a film take-up reel 99. The film feed roller 96 is connected to a film drive motor to be described later, and rotates forward and backward.

The spool shaft of the magazine 93 is connected to a motor (not shown) when mounted on the carrier 90, and the spool shaft of the take-up rule 99 is connected to a motor (not shown). In order to give a constant tension to the microfilm F between them, the spool shaft of the magazine 93 and the spool shaft of the take-up reel 99 are each driven by a motor with driving force such that they rotate in opposite directions. 6. The microfilm F wound in a roll around the spool shaft of the magazine 93 exits the magazine 93, passes through feed rollers 95 and 96, passes through guide rollers 97 and 98, and is wound onto a take-up reel 99.

The microfilm F is moved forward or backward by the feed rollers 95 and 96 d. Hereinafter, when the film is fed from the magazine 93 to the take-up reel 99, it will be referred to as forward feeding, and on the other hand, when the film is fed from the take-up reel 99 to the magazine 93, it will be called backward feeding.

When the microfilm F passes over the aperture 91, the lamp 3
It is illuminated by light from 9. ioo and tot are mark detection devices that are arranged along the microfilm feeding path and detect the marks of the frames placed at the copying position, and detect the marks provided on both sides of the film F.

As shown in Figure 6, the microfilm F has information recorded on each frame f arranged in a line on the film, and a frame mark ml is placed corresponding to each frame, indicating the information content related to it. A mark m2 is placed corresponding to the first piece of the pieces. The piece mark 112 is placed on one side of the piece, and the piece mark 112 is placed on the other side of the piece, so that the two marks can be distinguished.

Information is recorded on the quality pieces in order of pages starting from the leading edge of the film.

In FIG. 6, pieces A1, A2. B, ・
B2 and B3 are each one piece of information, and a piece mark Ill is attached to each piece, and an item mark m2 is attached to the first piece A, , B, which records the information on the first page of quality. There is. Note that one piece of information is not for multiple pieces, but for l.
Although the information may be composed of only pieces, the present invention can of course be applied to such information as well.

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.
99.

Of the mark detection devices shown in FIG. 5, 100 is a piece mark detector for detecting the piece mark ml, and 101 is a piece mark detector for detecting the piece mark m2, each of which has a photoelectric conversion element. Each mark detector is connected to an information retrieval device and a print control circuit, which will be described later.

When the carrier holding stand 50 is at the home position, an image of a frame of the microfilm F on the film carrier 90 placed at a position corresponding to the condenser lens 40 is projected onto the screen 81 through the optical system.

FIG. 7 shows an information retrieval device, where lot is the subject mark detector shown in FIG. 5, and 110 is the subject mark detector lot.
a counting circuit for counting the number of mark signals output from the 111
is a comparison circuit which compares the current count value of the counting circuit 110 with the case number of the desired case inputted from the search number input capotain 12, and is composed of a subtraction circuit. 112 is a D/A converter, 11
3 is a forward/reverse switch for switching the film feeding direction; 114;
A 1f film drive motor is connected to the film feed roller 96.

Now, if the case number of the desired case to be searched that has been input into the search number input capotan 12 is A, and the number of case marks counted by the counting circuit 110, that is, the count value is B, then in the subtraction circuit A-B=
C is generated, the +-- of this C is determined, and a signal corresponding to the +/- sign and numerical value is sent 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, drives the drive motor 114, feeds the film F by the feed rollers 95 and 96, and stops the film when the output of the subtraction circuit ill becomes zero. stop+l
G. Therefore, when the subject mark of the first frame of the desired frame material is detected by the subject mark detector 101, the first frame is placed at the copying position where it is illuminated by the lamp 39, and the film F is stopped. The image is projected onto the screen 8 and can be observed.

FIG. 8 shows the print control circuit, where 11 is the copy button shown in FIG. 1, 100 and 101 are the piece mark detectors and single mark detectors shown in FIG. 5, and 150 is the copy button 11 pressed. This film backward feeding device operates in response to a high level copying command signal generated when the film is operated, and outputs a high level signal from the end-C during forward feeding.

Reference numeral 151 is a device for feeding the film backwards, and outputs a high level signal from the terminal e while the film is being fed backwards.

1.52, l 53 is a delay circuit, 154 is a copying circuit, and when receiving the signal output from the delay circuit 153, the forward clutch 71 is turned on, and the image forming means of the print section l is printed in a predetermined order. It is activated and copies the image on the microfilm placed at the copying position.155 is a timer.G, ・02-----G is an AND gate, G is an OR gate, FF, ・FF2 is a printer. The input terminal of the timer 155 is connected to the output terminal of the piece mark detector 100, and the output terminal is connected to the AND gate G+ via the OR gate G6.
+ Connected to the input terminal of G3.

The forward feeding device 150 is constructed as shown in FIG.
The set input terminal a of the flip-flop FF3 is connected to the copy button 11, the reset input terminal is connected to the output terminal of the AND gate G1, and the set output terminal C is connected to the aforementioned film drive motor via the forward drive circuit 156. 114, and the reset output terminal d is connected to a brake mechanism (not shown) for stopping the film feed rollers 95 and 96.
It is connected to the. One input terminal of the AND gate Gl is a flip-flop FF constituting the forward feeding device 150.
3, and when the film F is being fed forward, a high level signal is sent from the output terminal C of the film forward feeding device 150. The reverse feed device 151 is also configured in the same manner as the III forward feed device,
When the film F is being fed backwards, the backward feeding device 151
A high level signal is output from the output terminal e of the ant gate G2.
is sent to one input terminal of

It is assumed that mark detectors 100 and 101 generate high-level mark signals when receiving optical signals from marks.

Next, the operation of copying desired information in the above-mentioned apparatus will be explained.

First, the information retrieval device searches for information on the desired item to be copied in the microfilm F by the above-described operation. For example, in FIG. 6, if piece B, 82 φ83 is set as the desired item information, the item mark m2 placed corresponding to the top piece B is detected by the item mark detector 101, and piece B1 It is assumed that the information of is projected on the screen 8-1-.

Next, when the operator presses the copy button 11, the copy 'rf
The forward feeding device 150 is activated by a copying command signal output from the button 11, and the film F is transferred to the feeding roller 95.96.
is fed forward in the direction of arrow a in FIG.

On the other hand, by pressing the copy button 11, the flip-flops FF, FF, and FF are pressed.

While the film F is being fed forward, when the subject mark detector 101 detects the subject mark of the next information of the desired information, that is, the subject mark m2 closest to the last frame B3 of the desired subject, the subject mark detector 101 outputs the subject mark m2. The film is stopped by the output signal of the AND gate G1, and after a predetermined time (after the film F has completely stopped), a backward feed signal is output from the delay circuit 152. This signal activates the reverse feed device 151,
The film F is fed backward by the feed rollers 95 and 96 in the opposite direction to that described above, that is, in the direction indicated by the arrow in FIG. ff16. During backward feeding of film F, frame mark detector 10
When 0 detects the frame mark of the last frame of the desired frame, that is, the frame mark of frame B3, the AND gate G2 listens, and the output signal of the AND gate stops the film. After stopping t=8), a print signal is output from the extension circuit 153, and this print signal activates the copying circuit 154 to move the carrier holding table 50 and copy the frame B3.

On the other hand, the flip-flop FF is set by the output signal of the AND gate G2.

When the copying operation of the last piece B3 is completed, it is shown in FIG. The microswitch S2 that detects the position of the carrier holding base 50 is turned on, and the print drive circuit 15 is thereby turned on.
A copy end signal is output from 4.

Note that this copy end signal may be generated in conjunction with other operations of the print section 1, but it is preferable to generate it after the exposure operation is completed.

Since flip-flop FF2 is in the reset state, when GM 'i' end 4rj is output, AND gate G4 is opened, a signal is output from AND gate G4, and this signal causes film backward feeding device 151 to operate again. The film is fed backwards.

By this time, the copy sheet S on which the image of frame B3 has been copied in the print section 1 is discharged to the discharge tray 6.

11 after the film! ; The film F is again fed backward by the operation of the feeding device 151, and the frame mark detector lo is detected.

When detecting the frame mark of frame B2 of film F1-, the film is stopped, and frame B2 is copied in the same manner as described above. When the copy paper S on which the image of frame B2 has been copied is discharged to the discharge tray 6, this copy paper is stacked on top of the previously discharged copy paper.

After the copying of frame B2 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 copy paper S on which frame B has been copied is detected as described above. It is ejected to the ejection tray and stacked on top of the second sheet of copy paper.

On the other hand, when the piece mark of piece B is detected, the item mark detector 101 detects the item mark m2 of piece B1, and the AND gate G3 listens to the mark signal output from the item mark detector 101 at this time, and FF2 is set. Print drive circuit 15 after copying of frame B1
4, a copy end signal is generated, but the flip-flop F
Since F2 is in the set state, the AND gate G4 does not open, and the output of the signal for operating the backward feed device 151 from the AND gate G4 is prohibited, so that film advance and copying operations are not performed. On the other hand, when the copy end signal is generated, the AND gate G is opened, and the output signal of the AND gate G5 causes the display unit (not shown) to display the number indicating that the copying of the desired piece has been completed, or the lamp 39 is turned on and the image of the first frame B1 is projected on the screen to notify the completion of the copying operation. Thereafter, the user searches for other information using the search device 111 in the same manner as described above, and by operating the copy button after search, the desired search information is copied in the same manner. Therefore, by simply operating the copy button once, the operator can automatically copy each piece of the desired item and obtain copies aligned in order, and as in the past, the pieces are duplicated and then rearranged in order. Copying can be done extremely easily without the need for special plywood.

By the way, the desired piece of information is the last RR on the film.
For example, in the case of the information in FIG.
If the frames X+ and X2 are the information frame materials for the last frame of film 1- (there are no frames to the left of frame x2 in Figure 6), then after searching for the first frame x of the desired frame, When the copy button is operated to advance film F in the same manner as described above, the next mark does not exist on the film, so the film is stopped as is, and then the film is advanced backwards and the last frame x 2 is Therefore, in FIG. 3, the timer 155 is activated by the mark signal generated when the piece mark detector 100 detects the piece mark. The timer 155 outputs a high-level pulse signal when a set time has elapsed after activation, and when it receives the next mark signal before the set time elapses, it is reset and starts operating again.

The set time of this timer 155 is set to the time required to feed the film a distance longer than the distance between the farthest adjacent frame marks in at least one frame material.

That is, the timer outputs a pulse signal when it operates for a time longer than the time interval of mark signals generated for each piece mark in one piece of information.

Therefore, when the piece mark detector 100 detects a piece mark, the timer 155 is activated, and if the piece mark detector 100 detects the next piece mark before the timer operates for the set time, the timer 155 is reset and reset. It starts working again. In other words, if the piece mark is detected within the set time of the timer, a pulse signal will not be output from the timer 155.
When the film is fed to a portion near the end and the last frame mark on the film (the frame mark of frame X2 in FIG. 6) passes the mark detection position of the frame mark detector 100,
A pulse signal is output from the timer 155 after a set time.

Therefore, during forward feeding, after the subject mark detector 101 detects the last subject mark mx, even without detecting the subject mark, the frame mark detector 100 detects the last frame x2 of the film 1-. After a set time has elapsed after detecting the frame mark, the timer 155 outputs a pulse signal, and this pulse signal opens the AND gate G1 via the OR gate G6, and the signal output from the AND gate G1 causes the film to stop. The delay circuit 152 is activated, and a backward feed signal is output from the S delay circuit, and this signal activates the backward feed device 151. Thereafter, copies are automatically made from the last two pieces of the desired item in the same manner as described above. It will be done.

Note that the timer may be activated by the signal from the piece mark detector instead of the signal from the piece mark detector, and in this case, there is 8 yellow that changes the set time of the timer. When photographing information on film, blank areas (non-image areas) that are longer than the normal spacing between frames may be provided between each company's information frames (film). There are no piece marks or item marks),
Even when using a film with long blank areas like this, the next mark can be detected if the mark next to the mark of the desired mark is farther from the last frame of the desired mark than usual. Since the forward feeding of the film can be stopped by a signal from the timer before the film is moved forward, and then the film can be fed backward, the last frame can be quickly placed at the copying position and copying can be started.

Note that the present invention can also be used with a film in which information is recorded in page order from the rear end of the film; in this case, the film is fed forward or backward, or in the reverse order of the previous embodiment. It turns out.

In this case as well, the subject mark is placed on the side of the top (first page) frame.

As described in 1-1 above, according to the present invention, even if a mark is no longer detected during film feeding, it is possible to automatically copy a set of frames related to information content, and moreover, it is possible to automatically copy a set of frames with related information contents. Since copying is started, copies can be obtained in order, which is extremely convenient, and there is no need for a special machine that can print one page.
