Abstract

PURPOSE:To easily detect a place where the burn-out of a lamp is caused based on a lamp burn-out mark by looking a developed film and to easily judge that the abnormality of an image photographed on the film is caused by the burn-out of the lamp by obtaining such constitution that the burn-out of the lamp of an original is detected and the lamp burn-out mark is imprinted on the film. CONSTITUTION:An original carrying means, an exposure lamp, a lamp burn-out detection means 150 which detects the disconnection of the lamp, a light emission means 86 and a control means 88 are provided. In such a case, when the burn-out of the lamp is detected by the detection means 150, the lamp burn-out mark is imprinted on the film by the control means 88. Then, when the original is loaded again, it is continuously photographed after the lamp burn-out mark. In such a way, when the disconnection is caused, such an effect is imprinted on the film 34. Thus, the position where the burn-out of the lamp is caused is easily detected by looking the developed film 34 and it is easily discriminated only by looking the neighborhood thereof whether the original is repeatedly photographed to be overlapped or not.

Description

Detailed Description of the Invention (Industrial Application Field) The present invention is applied to a rotary camera that photographs an original and a film while moving them in opposite directions. This invention relates to a lamp burnout mark imprinting device that detects the lamp burnout mark and imprints the lamp burnout mark on the film.

(Technical Background of the Invention) A rotary camera is one type of microfilm camera. In this method, the original and the film are moved in opposite directions, and images are sequentially and continuously taken from one end of the original through a narrow slit.

Here, while an original is being photographed, the lamp may go out due to breakage of the filament of an exposure lamp that illuminates the original. When this lamp burns out, the film will continue to run without being photographed. Furthermore, when the lamp burns out, it is necessary to replace the lamp and then resume photographing an appropriate number of times before the document in which the lamp burnout occurred. For this reason, documents will be photographed redundantly in the vicinity of the document where the lamp has burnt out. However, since the film contains a reduced image, it is difficult to check where the lamp burnout occurred or which documents are duplicated by looking at the film.

Furthermore, when a lamp burns out, the film usually becomes blank, but it is difficult to know with certainty the cause of the abnormality that has occurred in the image just by looking at the film after development. For example, there is a problem in that it is difficult to determine whether this long blank space is caused by the completion of photographing the document, or whether it is caused by a burnout of the lamp and whether there is a continuation.

(Purpose of the Invention) The present invention has been made in view of the above circumstances, and by imprinting a message to that effect on the film when a lamp burnout occurs, it is possible to see the film after development and see that the lamp burnout has occurred. To provide a device for imprinting a burnout lamp mark on a rotary camera, which makes it possible to easily detect the position where a document has been photographed, and to easily determine whether or not a document has been photographed repeatedly by looking only at this area. .

(Structure of the Invention) According to the present invention, this object is to provide a microfilm rotary camera for photographing an original and a film while moving them in opposite directions, and to provide a method for transporting a plurality of originals to successively pass through a photographing section. means, an exposure lamp for illuminating the document in the photographing section, and lamp-out detection means for detecting a break in the lamp;
A lamp-out mark imprinting device for a rotary camera, comprising a light-emitting means for imprinting data on the film, and a control means for imprinting a lamp-out mark by the light-emitting means and stopping photographing of the document based on detection of a lamp out. achieved.

Here, the lamp burnout detection means can be configured to detect lamp burnout when the amount of light from the lamp becomes below a certain level.

The light emitting means can be a one-dimensional light emitting means, and the document can be photographed on the film at the position where it is wound around the photographing roller, and the one-dimensional light emitting means can imprint the lamp burnout mark at this position.

Alternatively, the number of originals may be counted, and when the lamp burns out, the number of images taken up to that point may be printed along with the lamp burnout mark. It may be configured such that when the lamp burns out, the original is reinserted from the beginning, the original is fed to the point where the lamp burns out, and only the part beyond that point is photographed.

C) When the lamp burnout detection means detects a lamp burnout, the control means imprints a lamp burnout mark on the film. Then, when you input the original again, the original will be printed after this lamp out mark (.

FIG. 8 is a diagram showing an example of imprinting data on film, FIG. 8 is a diagram showing an example of imprinting a lamp burnout mark, and FIG. 9 is an operation flowchart.

First, an outline of the document conveying means will be explained based on FIG. 2.4.

In FIG. 4, the reference numeral 10 is an auto feeder, and the input port 12
Documents 14, such as handprints, are stacked and input, and a normal roller 16 contacts the top surface of the top document 14, while a reverse rotation roller 18 opposing this contacts the bottom surface of the document 14. Then, the stacked documents 14 are sent one by one from the top to the photographing section. Reference numeral 20 denotes a conveyor belt wrapped around an appropriate number of rollers. A roller unit 22 is pressed against the upper surface of this belt 20, and the document 14 fed from the auto feeder 10 is sandwiched between the two and conveyed. It will be done. The document 14 is now turned upwards and raised by appropriate transport rollers past the photographing glasses 24,24. The original 14 is then sandwiched between the ejection roller 26 and the belt 28 pressed by the ejection roller 26 and ejected to the stacker 30. The originals 14 are placed in this stacker 30 in the order in which they are printed.
It accumulates. Here, the original 14 is imaged while passing between the photographing glasses 24 and 24, and the front and rear edges of the original 14 entering the glass are detected by the original detection sensor 32. That is, the light emitting element 3 such as L E'D is placed across the path of the original 14.
3 is arranged to face the sensor 32, and the sensor 32
Passage of the original 14 is detected by intermittent exposure of the original 14 to this light.

When the original 14 passes through the photographing glasses 24, 24, both sides thereof are simultaneously photographed on a film 34, which will be described later. That is, the second
As shown in the figure, the original 14 is illuminated by a plurality of exposure lamps 36.36 arranged on the outside of both photographing glasses 24.24, and the images of the front and back screens of the original 14 are reflected by mirrors 38a, b, 40, respectively. .42.Photographing lens 4 by 44
6 and forms an image on the film 34 located below this lens 46. Here, the front and back images formed on the film 34 are formed by the slit 48 into long linear images in a direction perpendicular to the feeding direction of the original 14.

A shutter 50 is located above the photographing lens 46 and interrupts the passage of photographing light.

Next, the feeding path of the film 34 traveling at a constant speed below the lens 46 will be explained based on FIG. In this section, 52 is a supply side spool of the film 34, and the film 34 supplied from this spool 52 is fed to the guide roller 5.
4. The film is wound onto a winding-side spool 60 via a photographing roller 56, a guide roller 58, and the like. 62 is this spool 6
It is a cutter placed in front of 0, and is a cutter placed in front of development key 1, which will be described later.
It is activated by pressing 08. Machine image roller 56 here
is located at a higher position than the guide rollers 54 and 58, and the film 34 runs in close contact with the upper half circumference of the image roller 56. Note that the photographing lens 46 is located above this machine shadow roller 56, and the reduced projection image is projected onto this machine shadow roller 56.
The image is formed on the upper film 34. Further, the guide roller 58 is rotated by a motor at a constant speed to determine the feeding speed of the film 34.

A pair of take-up spools 60 are held on both sides of a horizontal rotating shaft 64 (only one is shown in FIG. 5). A disc 66 is fixed to the right end of the spool 60, and a drive belt 68 is disposed between the disc 66 and the spool 60. This drive belt 68
is wound around a driving roller 70 and a driven roller 72, and travels counterclockwise (in the direction of the arrow) as shown. When the driven roller 72 is moved toward the subur 60 by an electromagnetic nozzle (not shown), the belt 68 comes into contact with the periphery of the spool 60, causing the spool 60 to rotate clockwise (in the direction of the arrow) in FIG. Film 34 shot in this state
is wound up, and when a predetermined amount of photographing is completed and a "develop" key 108, which will be described later, is pressed, the cutter 62 cuts the film 34. Furthermore, when the driven roller 72 is moved toward the disc 66 and the belt 68 is brought into contact with the disc 66,
By rotating the rotating shaft 64 by 180 degrees, the position of the spool 60 can be changed to the left or right with the rotating shaft 64 in between.

When the left and right sides of the spool 60 are switched, the driven roller 72 moves toward the spool 60 again and rotates the spool 60 clockwise. Film 34 that was shot and wound for this purpose
This time, it will be sent out in the opposite direction, and it will be sent to the developing processing section 7.
Sent to 4.

The development processing section 74 is located below the spool 60, and includes a development tank 76A, a fixing tank 76B, a washing tank 76G,
76D. The photographed film 34 sent out from the spool 60 is transferred to each of these tanks 76A-D.
After passing through the interior and being processed, it is sent to a drying section 78.

The tanks 76A to 76D are integrally made and can be moved up and down, and by lowering them, the tanks 76A to 76D are removed from the path of the film 34 and the processing liquid is exchanged.

The drying section 78 transfers the film 34 that has been washed with water to the heater 8.
The film 34 dried here is stored in a film tray 82. This film tray 82 may be provided with a take-up reel 84, and the film 34 may be wound directly onto this reel 84.

86 is a line LED as a one-dimensional light emitting means, which is made by arranging minute light emitting diodes in a line. This line LED 86 is located on the side of the photographing roller 56,
In the range where the film 34 is in close contact with the photographing roller 54, that is, within the upper half circumference of the photographing roller 54,
A one-dimensional image is formed in the width direction of the film 34.

Each LED constituting each pixel of this line LED 86 is
Control means 88 (first
(Fig.) is selectively blinked, and predetermined data is imprinted on the film 34. This control means 88 includes a CPU 90,
ROM92, RAM94, input interface (IF
) 96 and an output interface 98. The feed speed of the film 34 is detected by an encoder lOO attached to the guide roller 58, and its output is read into the CPU 90 via the input interface 98 and stored in the RAM 94 as necessary. Also film 3
The data to be imprinted on the paper 4 is inputted from the keyboard 102, a lamp burnout detection means 150, a sheet number detection means 90A, etc., which will be described later.

The keyboard 102 has a data input key group 104, a space key 106, a development key 108, etc. as shown in FIG. 0 is displayed as appropriate.

The CPU 90 outputs, via the output interface 98, a signal that causes each pixel of the line LED 86 to selectively emit light in accordance with a predetermined operation program stored in the ROM 92. Based on this output, the drive circuit 1) 2 selectively causes each pixel to emit light, thereby imprinting predetermined data onto a predetermined position on the film 34.

The data to be imprinted can be, for example, the data shown in FIG. 7, which is inserted into the beginning and end of the photographed portion of the film 34. The date can be input by pressing the "Date" key in the data input key 104, and in the case of photographing a bill, the bank code, branch code, etc. can also be automatically input. Hold down the "Shift" key and "
You can command the time by pressing the "Date" key. Furthermore, by pressing the "Start" key, an instruction can be given to record "Start" in capital letters at the center of the width of the film 34. Also, use the rAJ~rJJ keys and
Using the ``shift'' key, you can command pre-registered characters such as ``commercial bill'' and ``other store ticket.'' After completing these commands, pressing the "confirm" key starts the imprinting operation. Further, after the image of the original 14 is finished, by pressing the "end" key and the "confirm" key, it is possible to command recording in the capital letters. The data to be recorded is the photographed front and back images 14A,
Blip 1) 4 may be recorded outside the frame of 14B.

Note that the "Space" key 106 is used when the film 34 is not photographed (it is used when the film 34 is not photographed).
When the key 108 is pressed after the exposure is completed, the film 34 is cut by the cutter 62 and development is started.

Next, a description will be given of imprinting a mark indicating a lamp out (lamp out mark).

When the lamp 36 is burnt out, the lamp burnout detection means 150 (
(Fig. 1). This means 150 includes a plurality of light sensors 152.15 which detect the light of each lamp 36 separately.
2 and a comparator 154 that outputs a lamp burnout signal i when the amount of light from each optical sensor 152 falls below a certain level. Therefore, when one of the lamps 36 burns out, the output of the corresponding optical sensor 152 becomes low level, and the comparator 154 outputs a lamp burnout signal ρ to the control means 88.

The CPU 90 also controls a sensor 3 that monitors the passage of the original 14.
It also has the function of a number detection means 90A that counts the outputs of 2 and calculates the number of shots.

When the lamp burnout detection means 150 detects a lamp burnout, the control means 88 imprints the lamp burnout mark M and the number of shots N at this time on the film 34 (FIG. 8).

(motion) Next, the overall operation of this embodiment will be explained using FIG. 9.

First, necessary data is imprinted on the beginning of the film 34 or at a desired position prior to the image of the original 14. For this imprinting, input the data to be recorded from the keyboard 102 with the film 34 stationary at the desired imprinting position (FIG. 9, step 200), confirm it on the data display panel 1)0, and then press " The process begins by pressing the "Confirm" key (step 202). That is, the film 34 starts to be fed, and the line LED 86 selectively emits light (step 204).

After data such as predetermined characters and numbers are imprinted, the originals 14 are stacked and set in the auto feeder 10, and the originals 14 are fed out one by one from the top, and the leading edges of the originals are detected by the original sensor 32. .

After the time set by the timer after this detection, the shutter 50 is opened, and images 14A and 14B of the front and back sides of the document are simultaneously photographed on the running film 34.

When the trailing edge of the document 34 is detected by the document sensor 32, the shutter 50 is closed after a certain period of time. The above operations are performed continuously to wind up the machined film 34 onto the spool 60 (step 206). When a predetermined amount of the document 14 has been imaged (step 208), the operator presses the "r end" key and then presses the "confirm" key to print the word "end" in large size (step 210, see FIG. 7).

When the lamp burnout detection means 150 detects lamp burnout during photographing (step 212), the control means 88 stops feeding the film 34 (step 214). Then, the film 34 is fed again, and the light emitting means 86 imprints the "lamp out" mark M and the "nth sheet" indicating the number n of shots completed without the lamp going out (step 216). The feeding of the film 34 is stopped. If the operator feeds the documents 14 into the auto feeder 10 again without changing the order from the beginning (step 218), the control means 88 will load the documents 14 up to the nth document immediately before the lamp burnout (step 218).
is skipped and photographing is started again from the (n+1)th image (step 220).

After photographing, press the "Develop" key 108 to release the cutter 6.
2 cuts the film 34. When this cut end is wound around the spool 60, the driven roller 72 of the belt 68 moves from the spool 60 side to the disc 66 side, and the belt 68 rotates the disc 66 by 180'', switching the spool 60 from side to side. 72 returns to the spool 60 side, rotates the spool 60 in the same direction, and sends out the film 34 to the development processing section 74. The developed film 34 is dried and guided to the tray 82.

In this embodiment, the number of plane images up to the point where the lamp burnout occurred is also printed along with the lamp burnout mark, but the present invention can achieve the intended purpose even if only the former is printed. Further, in the case where there are a large number of lamps, it is preferable to provide a separate optical sensor 152 for each lamp to detect lamp burnout. However, the number of optical sensors 152 can be reduced if the electrical wiring of a plurality of lamps is connected in series so that when one lamp burns out, all the lamps connected in series will burn out. .

It is preferable that the lamp burnout mark be expressed in characters large enough to be read with the naked eye, but a blip 1) 4 is placed outside the frame of the images 14A and 14B in the same position as the blip 1) 4 shown in FIG. 7 above. It may also be imprinted as a separate mark.

Although the one-dimensional light emitting element 86 is used in the above embodiment,
A two-dimensional light-emitting element may be used, and in this case, the film 34 is kept stationary for imprinting.

(Effects of the Invention) As described above, the present invention detects the burnout of the lamp on the original and imprints the burnout mark on the film.
If you look at the developed film, you can easily detect the location of the lamp burnout from this lamp burnout mark, and you can easily determine that the abnormality in the image taken on the film is due to the lamp burnout. Section (1)).

Here, the configuration of the lamp burnout detection means is simple if the lamp burnout is detected from the output level of the optical sensor that detects the amount of lamp light (Claim (2)). If the number of photographed documents is also imprinted, it is convenient to be able to accurately identify documents that have not yet been photographed (II Claim 4)).

If the image of the original is captured by wrapping the film around a photographing roller, and if the lamp burnout is also imprinted on this photographing roller, the length of the film traveling path can be shortened, making it suitable for downsizing the device ( Claim (3)).

4゜Also, store the number of shots in memory, and if you want to feed the original from the beginning again when the lamp burns out, feed the film up to or around this number of shots, and then start from the original where the lamp burnt out or just before that. If you continue the image from the original, the operation will be easier (ill query (5)
