Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a copying apparatus that automatically obtains a copy of a desired group of information frames in a microfilm having a large number of information frames.

In recent years, with the increase in the amount of information, microfilms on which a large amount of information is recorded vertically are widely used.

There are various types of microfilm such as roll film and fish film, and a large number of information frames are arranged in parallel on the film. Normally, when a large number of subject manuscripts are photographed on microfilm, one document (one unit) with related information content is photographed in sequence on a series of frames on the microfilm. Therefore, on the microfilm, groups of information frames with related information contents are consecutively arranged at regular intervals. For example, when photographing a patent specification on roll microfilm, one page of a patent specification is taken as one frame, and the information for one item is displayed on the first page in a group of information frames with the number of frames corresponding to the number of tributes to one item. This information group for one item becomes one item (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 microfilm using a copying machine equipped with an information retrieval device, first copy the information frame group at the beginning (first page) of the desired item on the microfilm that requires copying. After searching for a piece and finding the first piece of the desired item, place the first piece at the copy position (print position), then operate the copy button to copy the first piece, and after copying the first piece, The operator feeds the microfilm and places the next (second page) frame at the copying position, then operates the copy button to copy the next frame, and repeats the above operation for only one frame. By repeating this process, a desired copy of each piece is obtained.

With this method, the operator has to feed the microfilm frame by frame, position the frame at the copying position, and operate the copy button, making the copying process extremely cumbersome, time-consuming, and very time-consuming. It was inconvenient. Additionally, in general, in copying machines, copy paper is ejected to the copy paper output tray with the copy image forming side facing upward (so that the operator can immediately observe the condition of the copy image on the copy paper). Since they are stacked on top in the order of output, when you start copying the information of a desired item from the first frame, the copy sheets that are rolled side by side in the copy paper output tray one after another are copies of the frame of the last page of the group of information frames of the desired item. The copy paper with the .

For this reason, the stacking order of the copy sheets is reversed, and the operator has to rearrange the stacking order of the copy sheets so that they are in page order from the top 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. An object of the present invention is to completely eliminate the above-mentioned drawbacks, and to make it possible to automatically start copying information on a desired item from the frame of the last page by performing a single copying operation.
The purpose of copying is to arrange and stack pages in a predetermined correct order.

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.

The present invention will be explained below using specific examples shown in the drawings.

FIG. 1 shows the entire microfilm reader printer to which the present invention is applied.

In the figure, the entire apparatus is composed of a print section (copy section) 1, an image observation section 2 provided above the print section 1, and a print control section 3. On the left side of the machine box 4 of the print section 1, there is a cassette 5 for storing a large number of copies and a copy paper output tray 6. It can be replaced with a cassette containing the . The printing section 1 has various image forming means, and copies the projected image of the microfilm onto the copy paper fed from the cassette 5, and places the copy paper on which the copy image has been formed with the image forming side facing upward. Eject to the ejection tray 6,
Stack them on top in the order they are discharged. The machine box 7 of the observation section 2 is provided with a transmission screen 8 onto which the projected image of the microfilm is projected and an optical system that projects the image onto the screen 8, and the projected image of the microfilm is observed on the screen 8. be able to. The print control unit 3 includes a power switch 10 for supplying power to the entire apparatus, a copy button 11 for giving a command to copy each frame of a desired item,
Search items for desired items to be searched, such as a search number input button 12 for inputting a case number, and a copy number setting button 12 for setting the number of copies of information to be copied. 13 are arranged respectively.

As shown in FIG. 2, the printing section 1 has a photosensitive drum 15 having a transparent insulating layer formed on a photoconductive photosensitive layer, and the photosensitive drum 15 rotates at a foot speed in the direction of the arrow, The microfilm is positively 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 to light by the entire surface exposure lamp 19 to form an electrostatic latent image on the drum surface, and the developing device 20
The latent image is visualized. Next, the excess developer on the drum is squeezed out by a negative charger 21 without disturbing the image.
Then, the paper feed rollers 22, 23, 24 feed the cassette 5.
A sheet of copy paper (transfer paper) S sent from the photosensitive drum 15 is brought into close contact with the photosensitive drum 15, and the visible image on the drum 15 is transferred onto the copy paper S by the transfer charger 25. After the transfer, the copy paper S is separated from the drum 15 by a separation belt 26 and guided to a drying and fixing section 27. On the other hand, the remaining toner and developer are wiped off by a blade 28 that is pressed against the surface of the drum 15.
Repeat the next copy cycle again. Note that the paper feed roller 2
2 is constantly rotating, and when the drum 15 reaches a predetermined position, it descends in response to a signal generated and comes into contact with the topmost copy paper S in the cassette 5, sending out one copy paper from the cassette. After that, it rises again, and 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 loaves 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. The image of the illuminated microfilm frame is illuminated by the projection lens 34 as shown in the optical path a.
The entire image is enlarged and projected onto the screen 8 via mirrors 35, 36, and 37, or passes through the projection lens 34 as shown in optical path b, and is projected onto the mirror 35 and half mirror 38.
A part of the image is enlarged and projected onto the photosensitive drum 16 through a narrow mirror 41 and a shutter (not shown) in the form of a slit. Note that instead of the half mirror, a known total reflection mirror may be inserted into and removed from the optical path. Figures 1 and 4
In the figure, movable parts 47 and 48 are movably arranged on a pair of rails 45 and 46 arranged in parallel on the upper part of the machine box 4 of the printing part. The movable parts 47 and 48 fixedly support the carrier holding table 50 and reciprocate along the rails 47 and 48' integrally with the carrier holding table 50 by a drive mechanism to be described later. As shown in FIG. 4, the carrier holding stand 50 has a long hole 51 and a rectangular light guide hole 52 provided at a position corresponding to the condenser lens 401 in the machine box 4. 52 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 inorganic chain 68 is connected between this reduction sprocket gear 62 and other sprocket gears 63 to 67. It's being passed around. The sprocket gears 65 and 66 are each rotatably supported by a rotating shaft, one sprocket gear 65 being connected to the rotating shaft via a reverse clutch 70, and the other sprocket gear 66 being connected to a forward clutch 71. When the clutches 70, 71 are turned on, the corresponding sprocket gears 65, 66 and the rotation shaft are drivingly connected, and when the clutches 70, 71 are turned off, the respective sprocket gears are connected to each other. 65 and 66 rotate freely relative to the rotating ratchet. Sprocket gears 72 and 73 are fixed to one end of the rotating shaft of each sprocket gear 65 and 66, respectively, and an endless chain 74 is stretched between the sprocket gears 72 and 73. A small gear 75 fixed to the end of the sprocket shaft of the sprocket gear 66 and a large gear 76 are engaged with each other, and a wire 79 is wound around a pulley 77 fixed to the large gear 76 and an idler pulley 78. Both ends of 79 are fixed to pins 80 and 81 of movable 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, 71 is selectively operated, and when the forward clutch 71 is turned on in response to a copy command signal to be described later, the sprocket gear 66 and its rotating shaft are connected, and the small gear 75 and the large gear 76 are activated. The carrier holding table 50 is rotated and moved forward by the wire 79. On the other hand, when the reverse clutch 70 is turned on in response to a copy end signal, which will be described later, the sprocket gear 65 and its rotating shaft are connected, and the chain 7
4, the rotation shaft of the procket gear 66 rotates, and the carrier holding table 50 is moved back by the small gear 75, the large gear 76, and the wire 79. When both clutches 70, 71 are off, the rotating shafts of the respective procks 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 meshes with a gear 84 that is integrated with the photosensitive drum 15. Therefore, when the chain 68 is driven, the photosensitive drum 15 rotates in the direction of arrow C at a constant speed. Switches S, , S located at the top of the machine box 4
2 detects the position of the carrier holding stand 50; when the microswitch S, detects the carrier holding stand 50, the carrier holding stand 50 is at the home position; when the carrier holding stand 50 is located at the home position; 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 completed, the micro switch S2 switches 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 base 50 to move backward. When the microswitch SI 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 the microfilm carrier fixedly held on the carrier holding stand 5.
The carrier 90 is fixed to the carrier holding base 50 with screws.

Further, the film carrier 90 includes a fixed plate 94 for positioning the film magazine 93, and film feed rollers 95, 9.
6, film guide rollers 97, 98, and a film take-up roll 99. The film feed roller 96 is connected to a film drive motor, which will be described later, and rotates forward and backward. The spool core of the magazine 93 is connected to a motor (not shown) when the carrier 9 is attached, and also connected to the winding wheel 99.
The spool shaft is connected to a motor (not shown).

In order to apply a constant tension to the microfilm F between them, the spool ball of the magazine 93 and the spool shaft of the take-up reel 99 are each given a driving force from the outside of the motor so as to rotate in opposite directions. The microfilm F wound in a roll around the Subur 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 roll 99. The microfilm F is moved forward or backward by feed rollers 95 and 96.

Hereinafter, when the film is fed from the magazine 93 to the take-up roll 99, it will be referred to as forward feeding, and on the other hand, when the film is fed from the take-up roll 99 to the magazine 93, it will be called backward feeding. When the microfilm F passes over the closed opening 91, the lamp 39
illuminated by light from Mark detection devices 100 and 101 are arranged along the microfilm feeding path and detect marks on frames placed at the copying position, and detect marks provided on both sides of the film F.

As shown in Figure 3, the microfilm F has information recorded on each frame f arranged in a line on the film, and a frame mark m, corresponding to each frame, is placed to indicate information related to the information content. A matter mark m2 is placed corresponding to the first piece of the piece group.

The piece mark m is placed on one side of the piece, and the piece mark is placed on the other side of the piece, so that the two marks can be distinguished. In each group of frames, information is recorded from the beginning of the film to the younger Gongjun.

In FIG. 6, piece A.・A2, B.・B2 and & are each one piece of information, each piece is marked with a piece mark m, and the first piece A,, B, which records the information on the first page of each piece.
The item mark m2 is attached to the item.

It should be noted that one piece of information may consist of only one piece instead of a plurality of pieces, but it goes without saying that the present invention can be applied to such information as well. Also, microfilm F is the 6th
In the figure, the leading edge of the film is assumed to be on the right side, and the film is wound onto the winding reel 99 from the leading edge. Of the mark detection devices shown in FIG. 5, 100 is a piece mark m,
A piece mark detector 101 detects the piece mark m2, and a piece mark detector 101 detects 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 holder 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 8 via the optical system.

FIG. 7 shows an information retrieval device, where 101 is the subject mark detector shown in FIG. 5, and 110 is the subject mark detector 101.
a counting circuit for counting mark signals output from 111;
is a comparison circuit which compares the current count value of the counting circuit 110 and the case number of the desired case inputted from the search number input button 12, and is composed of a subtraction circuit.

112 is a D/A converter, 113 is a forward/reverse switch for switching the film feeding direction, 114 is a film drive motor,
It is connected to a film feed roller 96.

Now, if the case number of the desired case to be searched entered into the search number input button 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 created, the ten/- of this C is determined, and a signal corresponding to the ten/one 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, and outputs the feed roller 95.
, 96, the film F is fed, and the film is stopped when the output of the subtraction circuit 111 becomes zero. Therefore, the issue mark of the first piece of the frame group of the desired issue is detected by the issue mark detector 101.
When detected, the first frame is placed at the copying position illuminated by the lamp 39, the film F is stopped, and the image of the first frame is projected onto the screen 8, which can be observed. Figure 8 shows the print control circuit.
1 is the copy button shown in Figure 1, 100 and 101 are the 5th
The frame mark detector and frame mark detector 150 shown in the figure are film forward feeding devices that operate in response to a copy command signal at the level generated when the copy button 11 is pressed, and are fed forward. A high level signal is output from terminal c.

Reference numeral 151 denotes a film backward feeding device which outputs a high level signal from terminal e during backward feeding.

152 and 153 are delay circuits, and 154 is a print drive circuit. When the print signal outputted from the delay circuit 153 is received, the forward clutch 71 is turned on, and the image forming means of the print section 1 is operated in a predetermined order and placed at the copying position. Copy the image on the microfilm.

○．・G2...○5 is AND gate, FF.・FF2 indicates flipflop. The forward feeding device 150 is constructed as shown in FIG.
The set input terminal a is connected to the copy button 11, the reset input terminal b is connected to the output terminal of the AND gate ○, and the set output terminal c is connected to the aforementioned film drive motor 114 via the forward drive circuit 155. The reset output terminal d is connected to a brake mechanism (not shown) for stopping the film feed rollers 95 and 96. One input terminal of the AND gate G is connected to the set output terminal c of the flip-flop FF3 constituting the forward feeding device 150, and when the film F is being fed forward, a high level is output from the output terminal c of the film forward feeding device 150. signal is sent. The backward feeding device 151 is also configured in the same manner as the forward feeding device, and when the film F is being fed backward, a high level signal is sent from the output terminal e of the backward feeding device 151 to one input terminal of the AND gate G2. It will be done. It is assumed that the mark detectors 100 and 101 generate a mark signal of .

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

First, by the above-described operation, the information retrieval light is used to search the microfilm F for information on the desired item to be copied.

For example, in Figure 6, piece B. .&...& is the information of the desired item, the item mark m'2 placed corresponding to the first piece B, is detected by the item mark detector 101, and the piece B,
It is assumed that information of is projected on the screen 8.
Next, when the operator presses the copy button 11, the forward feed device 150 is activated by a copy command signal output from the copy button 11, and the film F is moved between the feed rollers 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, FF2 are reset. 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 m''2 closest to the last frame B3 of the desired subject, the subject mark detector 1
AND gate G is opened by the mark signal output from 01, the film is stopped by the output signal of AND gate G, and after a predetermined time (after film F has completely stopped)
A backward feed signal is output from the delay circuit 152, and this signal activates the backward feed device 151, so that the film F is fed backward by the feed rollers 95, 96 in the opposite direction to that described above, that is, in the direction of arrow b in FIG.

While the film F is being fed backwards, when the frame mark detector 100 detects the frame mark of the last frame of the desired frame, that is, the frame mark of Kenpaku 3, the AND gate G2 opens, and the film is stopped by the output signal of the AND gate. After a predetermined period of time (after the film F has completely stopped), a print signal is output from the delay circuit 153, and this print signal activates the print drive circuit 154 to move the carrier holding table 50 and move the frame &
is copied. On the other hand, flip-flop FF is set by the output signal of AND gate G2.

When the copying operation of the last piece is completed, as shown in Fig. 4,
The microstitch S2 that detects the position of the carrier holding table 50 is turned on, and thereby the print drive circuit 154
A copy end signal is output from.

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 the flip-flop FF2 is in the reset state, when a copying end signal is output, the AND gate G4 is opened and a signal is output from the AND gate G4. This signal causes the film backward feeding device 151 to operate again, and the film is fed backward. Ru.

The copy sheet S on which the image of frame & has been copied in the print section 1 up to this point is discharged to the discharge tray 6.

The film F is fed backward again by the operation of the film backward feeding device 151, and the frame mark detector 100 detects the film F.
When the frame mark of frame B2 above is detected, the film stops,
Copying of the piece is performed 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 superimposed on the previously discharged copy paper. After the copying of frame B2 is completed, the film F is fed backward 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 ejected in the same manner as described above. It is ejected to a 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 piece mark detector 101 detects the piece mark m' of piece B.
2 is detected, and at this time, the mark signal output from the event mark detector 101 opens the AND gate G3 and sets the flip-flop FF2.

After the copying of frame B is completed, the print drive circuit 154 generates a copy completion signal, but since the flip-flop FF2 is in the set state, the AND gate G4 does not open, and the signal for operating the backward feeding device 151 is not output from the AND gate G4. Output is inhibited, which prevents film advance and copying operations. On the other hand, when the copy end signal is generated, the AND gate G5 opens, and the output signal of the AND gate G5 causes a display unit (not shown) to display that copying of each frame of the desired item has been completed, or lights up the lamp 39. Then, the image of the first frame B is projected on the screen to notify the completion of the copying operation. Thereafter, the user searches for other information using the search device in the same manner as described above, and by operating the copy button after search, the desired search information is similarly copied. 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, without having to rearrange them in order after copying as in the past. Also, there is no need to provide a dedicated collating machine, making copying extremely easy. FIG. 10 shows another embodiment of the print control circuit, in which parts similar to the previous embodiment are designated by the same reference numerals.

13 is the copy number setting dial shown in FIG. 1, 200 is a counter that counts the copy completion signal output from the AND gate G5, and 201 is a comparison between the current counted value of the counter 200 and the number of copies set by the copy number setting dial 13. A comparison circuit compares two input numerical values every time the count value of a counter 200 changes, outputs a copy command pulse signal at an appropriate timing when they do not match, and does not output a copy command pulse signal when they match.

In the apparatus shown in FIG. 10, when copying N copies of a desired group of frames A, ~Ax, when the number of copies setting dial 13 is set to the number of copies N and the copy button 11 is operated, the information of the desired item is copied. The last piece Ax in the group of pieces is placed at the copy position, and from this last piece Ax to the first piece A. As described above, copies are made one copy at a time.

When the copying operation for one copy from the last piece Ax to the first horse ship is completed, a copy completion signal is output from the AND gate G5, and this signal is counted by the counter 200. In other words, the counter 200' counts the number of times one piece of information has been copied. When the counter 200 performs a counting operation, the comparison circuit 201 compares the counted value of the counter 200 and the set value of the number of copies setting dial 13, and if the two do not match, outputs a copy command pulse signal, and this pulse signal advances the film forward. The device is activated, causing the same operation as when the copy button 11 is operated. That is, the last piece Ax is placed at the copying position again, and copies are made one copy at a time from the last piece Ax to the first piece A. In this way, the second copy operation is performed. Thereafter, the copying operation is repeated one copy at a time in this order from Ax piece to A piece in the same manner as described above, and when N copies are made for A, to Ax piece, the count value of the counter 200 (becomes N). When the set number of copies N matches, the comparator circuit 201 does not output the copy command pulse signal, thereby completing the copying of the desired number of copies for the desired item.

In this way, a desired number of copies of the copy sheets arranged in order can be obtained. Note that the present invention can also be used with a film in which information is recorded sequentially from the rear end of the film, and in this case, the forward and backward feeding of the film is performed in the reverse order of the previous embodiment. Become.

In this case as well, the subject mark is placed on the side of the top (first page) frame. As described above, according to the present invention, it is possible to automatically copy a group of frames with related information content by using two types of marks on a film, and moreover, it is possible to copy a plurality of copies.
It is very convenient to be able to automatically obtain copies that are aligned in order, and there is no need for a special machine to align the pages.
