Abstract

PURPOSE:To easily detect a place where jam occurs based on a jam mark by looking a developed film and to easily judge that the abnormality of an image photographed on the film is caused by the jam by obtaining such constitution that the jam of an original is detected and the jam mark is imprinted on the film. CONSTITUTION:An original carrying means, a jam detection means 90A, a one-dimensional light emitting means 86 which imprints data on the film 34 and a control means 88 are provided. In such a case, when the jam is detected by the detection means 90A, the jam mark is imprinted on the film 34 by the control means 88 by selectively making the respective picture elements of the emitting means 86 flicker while the film 34 is fed. Then, when the original is loaded again, it is continuously photographed after the jam mark. In such a way, when the jam occurs, such an effect is imprinted on the film 34. Thus, the place where the jam occurs is easily detected by looking the developed film 34 and the existence of the double exposure of the original is easily discriminated only by looking the neighborhood thereof.

Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention is applied to a rotary camera that takes pictures while moving an original and a film in opposite directions, and detects a jam in the original. This invention relates to a jam mark imprinting device that imprints jam marks on 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.

Although the document is continuously fed at a high speed at a constant speed, the document may be fed unevenly due to folds or scratches on the document, or may become jammed in the conveying path, resulting in a so-called jam. When this jam occurs, it is necessary to correct the jam in the document and then perform photographing an appropriate number of times before the document in which the jam occurred. For this reason, the document will be photographed twice in the vicinity of the document where the jam has occurred.

However, since reduced images are recorded on the film, there is a problem in that it is difficult to confirm where the jam occurred or which document is duplicated by looking at the film.

Also, when a jam occurs, the image taken with the film usually becomes longer (elongated or the image jumps), but just by looking at the developed film, it is difficult to determine the cause of the abnormality in the image. For example, when a long blank space appears, it is difficult to determine whether the document has been photographed completely or whether there is a jam and there is more to be done.

(Purpose of the Invention) The present invention was made in view of the above circumstances, and when a jam occurs, by imprinting the fact on the film, it is possible to see the position of the jam by looking at the developed film. To provide a rotary camera jam mark imprinting device which can easily detect the area and easily determine whether there is duplicate photographing of a document by looking only at this area.

(Structure of the Invention) According to the present invention, in a microfilm rotary camera that photographs an original and a film while moving them in opposite directions, the present invention provides an original transport means for continuously transporting a large number of originals to a photographing section. a jam detection means for detecting a jam in the document in the document transport means; a one-dimensional light emitting means for imprinting data on the film; This is achieved by a jam mark imprinting device for a rotary camera, which is equipped with a control means for stopping photography.

Here, the jam detecting means can be configured to monitor the passage time of the document near the machine shadow part, and determine that there is a jam if the passage time becomes too long.

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 jam mark at this position.

Alternatively, the number of original documents may be counted, and when a jam occurs, the number of photographed documents up to that point may be imprinted along with the jam mark. It may be configured such that when a jam occurs, the document is reinserted from the beginning, the document is continuously fed to the point where the jam occurs, and only the part beyond that point is photographed.

(Function) When the jam detection means detects a jam, the control means selectively blinks each pixel of the one-dimensional light emitting means while feeding the film, thereby imprinting a jam mark on the film. Then, when the original is input again, the original will be photographed after this jam mark.

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. A conveyance belt 20 is wound around an appropriate number of rollers, and a roller unit 22 is pressed against the upper surface of this belt 20, between which the document 14 fed from the auto feeder 10 is sandwiched. The document 14 is then turned upward and is raised by a suitable conveyance roller through the photographing glass 24, 24.The document 14 is then passed between the ejection roller 26 and the belt 28 pressed against it. The originals 14 are pinched and discharged to the stacker 30. The originals 14 are accumulated in this stacker 3° in the order in which they were photographed.The originals 14 are photographed while passing between the photographing glasses 24 and 24, while the originals 14 entering here are A front end and a rear end of the document 14 are detected by a document detection sensor 32. That is, a light emitting element 33 such as an LED is arranged to face the sensor 32 across the path of the document 14, and the sensor 32 detects the light from the document 14. The passage of the document 14 is detected by intermittent detection.

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 become long linear images in a direction perpendicular to the feeding direction of the original 14 by the slit 48.

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 figure, 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. Here is the shooting roller 56
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 photographing roller 56. The photographing lens 46 is located above the photographing roller 56, and the reduced projection image is projected onto the photographing 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 this driven roller 72 is moved toward the spool 60 by a magnetic blade (not shown), the belt 68 comes into contact with the periphery of the spool 6o, rotating the spool 60 clockwise (in the direction of the arrow) in FIG. let Film 3 shot in this state

When the key 108 is pressed, the cutter 62 cuts the film 34.
is cut. When the driven roller 72 is moved toward the disk 66 and the belt 68 is brought into contact with the disk 66, the rotating shaft 64 is rotated by 180 degrees, and the position of the spool 60 is swapped to the left and right across the rotating shaft 64. be able to. When the left and right spools 6o are swapped, the driven roller 72 moves toward the spool 60 again and rotates the spool 60 clockwise. For this reason, the film 3 that was machined and wound
4 will now be sent out in the opposite direction, and will be sent to the development processing section 74.

The development processing section 74 is located below the spool 60, and includes a development tank 76A, a fixing tank 76B, and a washing tank 76C1.
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-D are integrally made and can be moved up and down, and by lowering the tanks 76A-D, the tanks 76A-D 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 machine shadow 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 100 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
Data to be imprinted on the paper 4 is inputted from the keyboard 102, jam detection means 9OA, sheet number detection means 90B, 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. It 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 112 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 manually. 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
By using the ``shift'' key, you can command registered characters such as ``commercial bill'' and ``other store world'' that have been registered in advance. 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,
The blip 114 may be recorded outside the 14B frame.

Note that the ``space j key 106'' is used when the film 34 is to be fed without photographing. ``Development''
When the key 108 is pressed after photographing is completed, the film 34 is cut by the cutter 62 and development is started.

Next, imprinting of a mark indicating a jam (jam mark) will be explained. When the original 14 gets stuck in the conveyance path, the output of the original sensor 32 does not change. C in Figure 1
The PU 90 has the function of a jam detection means 90A, and this means 90A monitors the change time of the output signal of this sensor 32, and if the change time interval is longer than a certain value (when the original 14
It is determined that there is a blockage or jam. Also this C
The PU 90 also has the function of a number detection means 90B that counts the output of the sensor 32 to determine the number of shots.

When the jam detection means 90A detects a jam, the control means 88 imprints the jam 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, prior to photographing the document 14, necessary data is imprinted onto the beginning of the film 34 or at a desired position. This imprinting is performed by manually inputting the data to be recorded from the keyboard 102 with the film 34 stationary at the desired imprinting position (FIG. 9, step 200), checking it on the data display panel 110, and then clicking "Confirm". It begins by pressing a key (step 2o2). 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 IO, 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-described operations are performed continuously to wind the photographed film 34 onto the spool 60 (step 206). Predetermined amount of manuscript 14
When the photographing is completed (step 208), the user presses the "R" key and then presses the "confirm" key, and the word "end" is printed in large size (step 210, see FIG. 7).

When the jam detection means 90A detects a jam 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 "F jam" mark and the "nth sheet" indicating the number n of shots that have been completed without jamming (step 216). Stop feeding. If the operator feeds the originals 14 into the auto feeder 10 again without changing the order from the beginning (step 218), the control means 88 feeds the originals 14 up to the nth sheet immediately before the jam occurs, and )
Photographing is started again from the first frame (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, the belt 68 rotates the disc 66 by 180 degrees, and the spool 60 is swapped left and right. Thereafter, the driven roller 72 returns to the spool 60 side, rotates the spool 6o in the same direction, and sends 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 shots taken up to the point where the jam occurred is also imprinted along with the jam mark, but the present invention can achieve the intended purpose even if only the former is imprinted. Further, although the sensor 32 for detecting a jam is also used as a sensor for detecting the number of images to be taken, it is of course possible to use separate sensors.

It is preferable that the jam mark be expressed in characters large enough to be read with the naked eye, but a mark separate from the blip 114 is placed outside the frame of the photographed images 14A and 14B at the same position as the blip 114 shown in FIG. It may also be imprinted.

(Effects of the Invention) As described above, the present invention detects a jam in a document and imprints the jam mark on the film. Therefore, by looking at the film after development, it is easy to identify the location where the jam occurred based on the jam mark. It can be detected easily that an abnormality in an image taken on a film is caused by a jam.

Here, the jam detection means can be configured simply by detecting a jam based on the passage time of the document, and it is convenient because the number of sheets that have been scanned can be counted using the signal of this passage time. (21, (4)).

If the image of the document is captured by winding it around a film-like image roller, and if the jam is also imprinted on this image-taking roller, the length of the film traveling path can be shortened, making it suitable for downsizing the device ( Claim (3)).

You can also store the number of shots in memory, and when a jam occurs and you want to reload the original from the beginning, you can feed the film up to or around this number of shots and start shooting from the jammed original or from a slightly earlier original. If it continues, the operation becomes easier (Claims (51, (61))
