Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a microphotographic device, and more particularly to a microphotographic device that alternately repeats a predetermined number of frame-by-frame shooting and blank feeding.

2. Description of the Related Art Conventionally, microphotography systems have been well known in which documents, drawings, etc. are photographed on 16-side, 35-side films and the films are stored.

This type of microphotography system uses roll film to continuously process a large amount of documents, and one uses sheet-like microfiche film with, for example, 5 x 12 frames. micro-
A system for shooting 60 frames on fish film is known.

The former system is extremely efficient as a large-volume processing system for centrally managing huge amounts of documents in large companies, etc., but it is also suitable for large-scale offices that require easy processing of small amounts of documents. In this case, there is a disadvantage that it is rather inconvenient and the above system cannot be adopted, and even in the latter system, in order not to waste film,
Since it is necessary to take 60 frames, it is basically impossible to eliminate the above drawbacks, and microfiche cameras inevitably have complicated structures and mechanisms, making them expensive and large in size. There were other implementation issues besides the above.

Due to these problems, a small office micro system for small offices, abbreviated as SOM system, has been proposed in recent years.
Microphotographic equipment for OM systems has been commercialized.

However, this type of microphotography equipment currently on the market is aimed at specific users, wastes a lot of film, cannot increase the shooting speed very much, and basically uses roll film. However, there were some drawbacks that made it impractical for use in general small films, such as the inability to overcome the drawbacks of .

In addition, the detailed description of the invention in Tokukan Sho 49-91456 discloses a photographic device using a long electrophotographic photosensitive film as a photosensitive film for microphotography; It uses electrophotographic photosensitive film, which is inferior to silver halide film, and is complicated by the process of charging, exposing, and developing for each frame, and is limited in size due to the need for spacing between each frame. said to be done,
There were several problems in implementation, and there were practical problems in that the product was mechanically complex and expensive.

In order to eliminate the above-mentioned conventional problems, the present applicant has filed a patent application dated June 7, 1939 (title of the invention ``Micro photographic system and photographic device J'', in which the largest length film is fed a predetermined number of frames and a fixed length After feeding the film while alternately repeating the blank feed and taking pictures sequentially during the frame advance, cut the film into units in which the blank area corresponding to the blank feed and the frame-by-frame part are unified, and cut each fixed length film. We are proposing a microphotographic system suitable for the SOM system, in which the image is developed in the following manner.

The present invention, like such a microphotography system, alternately repeats frame-by-frame feeding and blank-feeding a predetermined number of times to cut a microphotograph in which frame-by-frame areas and blank areas are alternately continuous to obtain film units. In a micro-photography system, it is possible to simultaneously record the photographic contents of the time-lapse section, the order of the photographs, or necessary organizing data such as notes in the front or rear margin of the time-lapse section. The purpose is to provide a micro photographic device.

The organizing data in the present invention includes alphabetical characters, numbers, simple figures, or a combination thereof;
In short, various data useful for identifying the time-lapse portion can be used, such as a business card, a memo, or even an enlarged view of a portion of the document to be photographed.

In the present invention, the organizing data is collected by a sub-photographing optical system provided separately from the main photographic optical system that takes frame-by-frame photographs of the original.
The image is formed forward or backward with respect to the film advance direction of the photographing position of the main photographing optical system, and is recorded in the margin at the same time as the first or last frame-by-frame recording.

As mentioned above, the method of recording organization data in the front or rear margin of the time-lapse section is particularly suitable for the microphotography system that performs cutting and development processing for each film unit, as described above. Even in a system that processes the largest film continuously without cutting it to a fixed length, it can be used as organizing data when the frame-by-frame portion is later cut out and stored in a film jacket for storage. The present invention will be described in more detail below with reference to the illustrated embodiments. One unit of microphotographic film (hereinafter simply referred to as film unit u) is the basis of the microphotography system according to this embodiment.

For example, as shown in Fig. 1, a 12-frame time-lapse section a corresponding to one line of micro-flash film is continuous with the front end of the time-lapse section a, and serves as a leader. , and a blank area b that is not scheduled to be photographed.Every time 12 frames are taken using a roll film for micro photography, a film unit u is cut and separated from the roll film, and each film unit u is developed thereafter. Perform processing, etc. The dimensions of the above film unit u, especially the frame dimensions of photographed area a, the frame pitch, the front and rear margin dimensions, etc., should be・
Set according to the standards applied to the film.

In addition, the width of the roll film used may be either 16 Yanagi or 35 Yanagi, but if you use 16 Yanagi, it is possible to
This is advantageous in that it can be compatible with fish films. In FIGS. 2 and 3 showing a photographic apparatus according to the present invention, reference numeral 1 denotes an original table provided on the top surface of a box 2 forming the main body of the photographic apparatus, 3 a lid that covers the original table 1 in an openable and closable manner;
4, 4 is a set of light sources arranged so as to uniformly illuminate the entire surface of originals such as documents and drawings placed on the original platen 1; 5 is a set of light sources as shown in FIG. 3; , a first mirror 6 which is a plane located below the document table 1 and facing the document table 1 at a predetermined inclination; 6 is a plane placed at an obliquely upper position that does not block the optical path leading to the first mirror 5; The pair of first and second mirrors 5 and 6 gradually focus the original image that has been reloaded on the document table 1, while also focusing the main photographing lens system and the sub-photographing lens system, which will be described later. The main photographing lens system forms an image of the document at a predetermined reduction ratio on its focal plane.

These light sources 4, 4, first and second mirrors 5, 6, and camera section 7 constitute a photographing optical system of this apparatus. For example, as shown in FIG. 6, the camera section 7 has a main optical system L that reduces the document ○ at a predetermined reduction ratio and forms an image at the photographing position. A time-lapse camera system 7a equipped with a shutter S that opens and closes against the film, and organizing data D such as notes and business cards placed on the side of the original 0 are connected to an appropriate position in front of the above-mentioned photographing position in the film feeding direction. It consists of a data photographing system 7b having a sub-optical system SL for imaging and a shutter s for opening and closing the sub-optical system SL with respect to the margin b of the film unit u.

In order to record the characteristic part 〇 of document 0 in the margin area b as organizing data, a sub-optical system SL' having a smaller reduction ratio than the main optical system L is provided to record the characteristic part 〇 in the margin area b. All you have to do is enlarge the part or ′ and record it.

The data shooting system 7 is the shirt s of the upper class data shooting system 7b.
If b is provided in the film advance direction of the time-lapse system 7a, it is opened at the same time as the first frame is taken, and if it is provided at the rear, it is opened at the same time as the last time-lapse, and necessary data is recorded in the margin text b. be able to do so.

The camera section 7' shown in FIG. 7 includes a data photographing system 7'b for recording numbers, characters, or a combination thereof as organization data in the margin b of the film unit u, and a stop-motion system 7a similar to the above. The data photographing system 7'b is attached to a data board d that can be operated with a dial, on which organizing data is sequentially printed, and is capable of illuminating only a predetermined section of the data board d when turned on. It consists of an illumination light source e installed so that If the opening operation of the shirt s is set in the same manner as described above, the illumination light source e
The shirt itself will also serve as a shirt. Note that a light emitting diode, a fluorescent display tube, etc. can be advantageously used as the light source. Again, in FIGS. 2 and 3, reference numeral 8 denotes a storage magazine in which a roll film 9 for microphotography is supported and stored on a reel 10 so as to be freely rewound. It is positioned and stored on the side of the

Reference numerals 11 and 12 denote a pair of film feed rollers located relatively close to each other on the left side of the camera section 7;
The leading edge of the roll film 9 fed out by a pair of guide rollers 13, 13' built into the film feeding section of the magazine 8 is caught at the focal plane, that is, in front of the photographing position, and a predetermined position is set in accordance with an operation command from a control means to be described later. Advance the film.

Between the guide rollers 13, 13' and the feed rollers 11, 12, the film is kept under constant tension to ensure good flatness, and at the photographing position, an exposure opening is set so that only a predetermined frame section can be exposed. (Not specifically shown.)
If necessary, pressing means such as a pressure plate may be used to press the film against the exposure aperture to ensure necessary flatness. 1
Reference numerals 5 and 16 denote cutting means which are located in front of the film feed rollers 1 and 12 and are composed of a pair of upper and lower cutting blades for cutting the film fed by the film feed rollers 11 and 12; It is operated when necessary in relation to the feed rotation of the film feed rollers 11 and 12 by a control means, which will be described later, to perform the prescribed length cutting of each film unit u as described above.

Reference numeral 17 denotes a developing processing chamber separated from the photographing optical system and the like by a partition plate 18 at the bottom of the box body 2;
2 is a two-layer processing tank consisting of, in order from the left side of the figure, a developing tank 20 containing a developing solution, a rinsing tank 21 containing a rinsing solution such as water, and a fixing tank 22 containing a fixing solution. This is a water washing nozzle for cleaning.

Further, 24 is a water tank for keeping the temperature of the processing tanks 20 to 22 constant, and the water temperature of the water tank 24 is maintained constant by an appropriate temperature control means (not shown). Solid line A in Figure 2
The curved path indicated by is a guide path for guiding the film unit u cut to a fixed length by the cutting means 15 and 16, and for example, as shown in FIG. Guide the film so that both sides are sandwiched between g and g, guide the film unit u to the developing processing chamber 17, and sequentially
After passing through the processes of development, rinsing, fixing, washing with water, and drying, the processed film unit u is guided into the film receiver 25.

The film unit u is fed after cutting by a large number of feed roller pairs r, . . . , r arranged in series along the upper sample guide path A. These feed rolls r,...,r are arranged at such a distance that their length along the guide path A is at least shorter than the length of the film unit u, and are independent as partially shown in FIG. They are each driven by a drive gear system GT. Further, as shown in FIG. 2, the length connecting the cutting point P of the film unit u and the point q in front of the single roller ra along the guide path A corresponds to the length of the film unit u. The pair of rollers r disposed in front of the developing tank 20 is fed by the rotation of the single roller ra provided in front of the pair of rollers, and after cutting, the developing process is performed. Only when the drive train GT of the system is driven by a processing command does the film unit u enter the developer tank 20 and start the development process. The feeding speed of the film unit u may be appropriately set in relation to the processing speed, and the feeding speed may be varied as necessary so as to realize an optimal processing process. Furthermore, if a two-class high-speed processing liquid is used as the processing liquid,
Processing can be speeded up, and a large number of film units u can be developed with a small amount of processing liquid. Next, referring to FIG. 8, the rotation control system of the feed rollers 11 and 12 will be explained.
It is a suitable intermittent rotation mechanism that rotates intermittently every rotation and feeds the roll film 9 by one pitch corresponding to one frame in one 1/6 rotation, and if necessary, it can be moved by two pitches by operating the operation button. It is preferable to be able to perform the above-mentioned feeding.

For each pitch of the feed rollers 11 and 12 of the intermittent rotation mechanism 3, an image is taken by opening and closing the shutter means (not shown) once. 31 is a small diameter gear coaxially attached to the feed roller 11, and 32 is a large concave gear that meshes with the gear 31. The gear ratio of these two gears 31 and 32 is set to 1:3, and the small diameter gear 31 and therefore the feed. loaf 1
The Daiyo Gya 32 is made to rotate once for every three rotations of 1.

The small diameter gear 31 and the large diameter gear 32 each have a cam 3.
3 and 34 are attached coaxially, and the first and second switches SW-1 and S are turned on and off by these cams 33 and 34.
Place W-2. The cam 33 turns on the first switch SW-1 once for each rotation of the small diameter gear 31, while the other cam 34 has a fan-shaped protrusion 34a provided over an angle of 1200 with respect to the rotation center. This fan-shaped protrusion 34a turns on the second switch SW-2 for 1/3 rotation of the large-diameter gear 32, and thus for one rotation of the small-diameter gear 31. The on signal of the second switch SW-2 is input to the intermittent rotation mechanism 30, and while the on signal is input, intermittent rotation of the feed loaf 11 is disabled and the feed roller 1 is continuously rotated once. As is clear from the foregoing, one rotation of the feed roller 11 corresponds to feeding the film six pitches, and therefore, one continuous rotation of the roller 11 results in six pitches of empty feeding. The phase relationship between the cam 33 of the small diameter gear 31 and the cam 34 of the large diameter gear 32 is such that the first two rotations of the small diameter gear 31 are 2/3 of the first half of the cam 34.
Corresponding to the rotation, the second switch SW-2 is set to be turned on at the fan-shaped protrusion 34a of the cam 34 during the next one rotation, and the first switch SW-1 is turned on at the first rotation of the cam 33. Sometimes, the first switch SW-1 and the second switch SW
-2 ON signals are simultaneously input, the AND gate 36 is opened, and the solenoid S connected to the output side of the AND gate 36 is opened.
OL is activated, and the upper blade 15 is pushed down by the operation of the solenoid SOL to cut the film. The installation position of the cutting means 15, 16, in other words, the cutting position P is determined from the center position B of the photographic lens system 7 by (the amount of film feed 1) - the rear end dimension m of the film unit u shown in FIG. ) a distance forward.

The above-mentioned blank feed amount 1 of the film is therefore equal to 6 pitches at the above-mentioned feed setting, and the trailing edge dimension m is equal to the sum of 1/2 pitch and the width c of the uncut portion at the trailing edge of the film unit U. . The dimension of this uncut width c is, for example, a jacket (
It may be set to an appropriate size according to the standard (see FIG. 7). In addition, as shown by the number 26 in FIGS. 2 and 3, a blower is attached to the upper inner wall of the box body 2 to supply external air to the upper part of the box body 2, and the above-mentioned partition plate 1
If air is sent from the upper side into the lower original image processing chamber 17 through the ventilation hole 18a which also serves as the film passage hole 8, and the evaporated gas of the processing liquid does not enter the upper side, the upper side It is advantageous to prevent corrosion of
If the processing chamber is sealed except for both □ 18a and 18b so that the air that entered the processing chamber 17 from the ventilation hole 18a is discharged outside the machine from the exit 18b of the finished film, the hot air from the drying section can be used to control the temperature. 24 will no longer be affected. Further, a switchboard section 40 constituting a command section of the photographic apparatus is installed on one side of the upper side of the box main body 2 as shown in FIG. 3, and as shown in FIG. on the side,
Main switch button 40, processing liquid temperature display lamp 4
2. A counter 43 indicating the remaining amount of film, an indicator 44 indicating the number of frames to be taken, a processing command switch 45,
By arranging the photographing switch 46, etc., it is possible to achieve a design that is convenient for operation.

In the above configuration, the photographer grasps the handle 3a of the lid 3 to open the document to be photographed, places it on the document table 1, and when using the organizing data D such as a memo, business cards, etc., the photographer places the document close to the document. After holding the document and data D flat with the lid 3 at a predetermined position, press the shooting button 46 to capture the first one.
Simultaneously with frame-by-frame photography, the shutter s of the data photography system 7b is activated to photograph the data D on the margin b of the film unit u.

In addition, when using numbers and characters as data for organization, operate the data board d using a dial, set the characters and numbers to be recorded, and turn on the light source e when shooting the first frame. The set characters and numbers are recorded in the margin b. For frame-by-frame shooting from the second frame onward, the day-to-day shooting systems 7b and 7b' are not activated, and shooting is repeated in sequence. When the shooting of 12 frames is completed, the feed roller 11 is automatically rotated one more rotation by the control program device. The film is then idly fed, and at the same time when one rotation of the feed roller 11 is completed, the solenoid SOL is activated and the cutting means 15 and 16 cut the film to a fixed length.

Further, when it is desired to carry out cutting processing when photographing 11 frames or less, when the processing command button 45 is pressed, the remaining photographing sections are continuously operated to perform the blank feed and the predetermined amount of blank feed to perform standard length cutting. The film unit u that has been cut to a specified length is guided into the developing processing chamber 17 along the guide path A by the feeding flow r, . After sequentially passing through a developing tank 20, a rinsing tank 21, and a fixing tank 22, and being developed and fixed, the film unit u is washed with water by a nozzle 23 and dried, and the dried film unit u is fed into a film receiver 25.

In addition, when the temperature display lamp 42 indicates that the set value of the processing temperature control means has not been reached, the photographing button 46 may not be activated even if the photographing button 46 is pressed, and the next photographing may be performed in parallel while the processing after cutting is in progress. This can be easily carried out using ordinary control techniques, but in this way, it is possible to prevent photographing failures and to prevent deterioration of photographing efficiency due to waiting for processing.

If the film unit u with the organizing data recorded in the margin b in this manner is stored in a row of a commercially available film jacket J as shown in FIG. 9, there is no risk of powder loss.

When processing a large number of documents at once, the first
If you record a symbol indicating the order of shooting (for example, R-1 as shown in Figure 1) in the margin when taking pictures of each frame, you can check the order of pushing into the jacket J or the jacket that should be pushed. There is no risk of making mistakes, so it is convenient for organizing. In this way, each film unit u is arranged and inserted into the jacket J, and when the predetermined editing is completed, the margin part b is cut off from the stop-motion part a in the jacket and removed.

It should be noted that the apparatus shown in the above embodiments is merely an example of the photographic apparatus according to the present invention, and it goes without saying that various changes can be made within the scope of the technical idea of the present invention.

As is clear from the detailed description above, according to the present invention, organizing data for each film unit can be appropriately recorded as necessary in the margin area that constitutes the film unit together with the stop-motion area. Even in small offices that require copying of a small number of manuscripts of different types, microfilm can be organized and edited without fail, such as by inserting it into a jacket, based on the recorded organizing data after the film has been developed. You can take advantage of the jacket's advantages.

Further, in the present invention, since the organizing data is recorded in the margin area using a separate photographing optical system, the organizing data can be recorded in a large size, and organizing and editing can be easily performed.
