Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention is applied to a rotary camera that shoots an original and a film while moving them in opposite directions, and detects a jam (jam) of the original. The present invention relates to a jam mark imprinting device that imprints a jam mark on a film.

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

Here, the document is continuously fed at a high speed at a constant speed. However, the document may be misaligned due to folds or scratches on the document, or jammed in the conveyance path to cause a so-called jam. When this jam occurs, it is necessary to correct the jam of the original document, and then to shoot back an appropriate number of times before the original document in which the jam occurs. Therefore, the originals are duplicated and photographed in the vicinity of the jammed original. However, there is a problem that it is difficult to see where the jam occurred and which originals are duplicated by looking at the film because a reduced image is taken on the film.

Also, if a jam occurs, the captured image of the film is usually lengthened or the image jumps, but just by looking at the film after development, it is possible to know exactly what caused the abnormality that occurred in this image. Was difficult. For example, when a long blank space occurs, there is a problem that it is difficult to judge whether the photographing of the document is completed or a jam occurs and there is a continuation.

(Object of the Invention) The present invention has been made in view of such circumstances,
When a jam occurs, the fact is printed on the film so that the position where the jam occurs can be easily detected by looking at the developed film. It is an object of the present invention to provide a rotary camera jam mark imprinting device capable of easily determining whether or not an image has been captured.

(Construction of the Invention) According to the present invention, an object of the present invention is to provide a microfilm rotary camera for photographing a document and a film while moving the document and film in opposite directions. A jam detecting means for detecting jamming of the original by the original conveying means, a one-dimensional light emitting means for imprinting data on the film, and a jam mark imprinted by the light emitting means on the basis of jam detection for the original. This is achieved by a jam mark imprinting device of a rotary camera having a control means for stopping photographing.

Here, the jam detecting unit may be configured to monitor the passage time of the document near the photographing unit and determine that the document is a jam when the passage time becomes excessive.

It is possible to shoot a document on a film at a position wound around a shooting roller and allow the one-dimensional light emitting means to imprint a jam mark at this position.

Alternatively, the number of originals may be counted, and when a jam occurs, the number of captured images up to that point may be imprinted together with the jam mark. It is also possible to re-feed the original document from the beginning when a jam occurs, feed the original document to the place where the jam occurs, and shoot only the area ahead.

(Operation) When the jam detecting means detects a jam, the control means selectively blinks each pixel of the one-dimensional light emitting means while feeding the film to imprint the jam mark on the film. Then, if the manuscript is put in again, the manuscript is continuously photographed after the jam mark.

FIG. 5 is a side view showing the document feeding means, FIG. 5 is a front view showing a film feeding path, FIG. 6 is a view showing a keyboard, FIG. 7 is a view showing an example of imprinting data on the film, and FIG. FIG. 9 is a diagram showing an example of imprinting a jam mark, and FIG. 9 is an operation flow chart.

First, the outline of the document conveying means will be described with reference to FIGS.

In FIG. 4, reference numeral 10 denotes an auto feeder, and originals 14 such as bills are inserted into the input port 12 in an overlapping manner, and the uppermost original is placed thereon.
While the forward rotation roller 16 contacts the upper surface of the document 14, the reverse rotation roller 18 opposed thereto contacts the lower surface of the document 14. Then, the stacked originals 14 are sent to the photographing unit one by one in order from the top. Reference numeral 20 denotes a transport belt wound around an appropriate number of rollers.
22 is pressed, and the document 14 sent from the auto feeder 10 is sandwiched and sent between them. The document 14 is turned upward here, and is raised between the photographing glasses 24, 24 by an appropriate transport roller. The document 14 is discharged to the stacker 30 while being sandwiched between the discharge roller 26 and the belt 28 pressed by the discharge roller 26. The originals 14 accumulate on the stacker 30 in the order in which they were photographed. Here, the document 14 is photographed while passing between the photographing glasses 24, 24, while the front end and the rear end of the document 14 entering here are detected by the document detection sensor 32. That is, a light emitting element 33 such as an LED is placed in the sensor 32 across the passage of the document 14.
The sensor 32 detects the light from the document 14
Is detected, the passage of the document 14 is detected.

As the document 14 passes through the photographing glasses 24, 24, both sides thereof are simultaneously photographed on a film 34 described later. That is, as shown in FIG. 2, the original 14 is illuminated by a plurality of exposure lamps 36, 36 arranged outside the two photographing glasses 24, 24,
14 front and back images are mirrors 38a, b, 40, 4 respectively
The light is guided to a photographing lens 46 by 2 and 44, and forms an image on a film 34 located below the lens 46. Film here
The front and back images formed on the image 34 become linear images long in the direction orthogonal to the feeding direction of the document 14 by the slit 48. A shutter 50 is located above the taking lens 46 and interrupts the passage of the taking light.

Next, a film running at a constant speed below the lens 46
The feed route 34 will be described with reference to FIG. In this figure 52
Is a spool on the supply side of the film 34.
The film 34 supplied from the above is wound on the winding side spool 60 via the guide roller 54, the photographing roller 56, the guide roller 58, and the like. Reference numeral 62 denotes a cutter arranged in front of the spool 60, which is operated by pressing a developing key 108 described later. Here, the photographing roller 56 is located at a position higher than the guide rollers 54 and 58, and the film 34 runs in close contact with the upper half peripheral surface of the photographing roller 56. The photographing lens 46 is located above the photographing roller 56 and forms a reduced projection image on the film 34 on the photographing roller 56. The guide roller 58 is rotated at a constant speed by a motor, and determines the feed speed of the film 34.

The take-up spool 60 is held by a pair on both sides of the horizontal rotary shaft 64 (only one is shown in FIG. 5). A disk 66 is fixed to the right end of the spool 60, and a drive belt 68 is provided between the disk 66 and the spool 60.
Is provided. This drive belt 68 is a drive roller
70 and the driven roller 72, and travels in the illustrated counterclockwise direction (arrow direction). When the driven roller 72 is moved to the spool 60 side by an electromagnetic solenoid (not shown), the belt 68 contacts the peripheral edge of the spool 60 and the spool 60
Is rotated clockwise (arrow direction) in FIG. In this state, the film 34 that has been photographed is wound up, and when the photographing of a predetermined amount is completed and the “development” key 108 described later is pressed, the cutter 62
As a result, the film 34 is cut. Also this driven roller
When 72 is moved to the side of the disk 66 and the belt 68 is brought into contact with the disk 66, the rotary shaft 64 is rotated 180 °, and the position of the spool 60 can be switched between the right and left with the rotary shaft 64 interposed therebetween. When the spool 60 is left-right swapped, the driven roller 72 moves to the spool 60 side again, and rotates the spool 60 clockwise. For this reason, the film 34 that has been photographed and wound up is sent out in reverse this time, and sent to the development processing unit 74.

The development processing unit 74 is located below the spool 60 and includes a development tank 76A, a fixing tank 76B, and washing tanks 76C and 76D. The photographed film 34 sent out from the spool 60 is sequentially processed through these tanks 76A to 76D, and then sent to the drying unit 78. The tanks 76A to 76D are integrally formed and can be moved up and down. When the tanks 76A to 76D are lowered, the tanks 76A to 76D escape from the path of the film 34 to exchange the processing liquid.

The drying unit 78 heats and dries the film 34 having been subjected to the water-washing process by the heater 80, and the dried film 34 is stored in a film tray 82. The film tray 82 may be provided with a take-up reel 84, and the film 34 may be wound directly on the reel 84.

Reference numeral 86 is a line LED as a one-dimensional light emitting means, in which minute light emitting diodes are arranged in a line. The line LED 86 is located on the side of the photographing roller 56, and in the range where the film 34 is in close contact with the photographing roller 54, that is, in the range of the upper half peripheral surface of the photographing roller 54, a one-dimensional image in the width direction of the film 34. Image.

Each LED constituting each pixel of the line LED 86 is selectively turned on and off by the control means 88 (FIG. 1) in synchronization with the feed speed of the film 34, and prints predetermined data on the film 34. The control means 88 includes a CPU 90, a ROM 92, a RAM 94, an 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
The data to be imprinted on 4 is input from the keyboard 102, the jam detecting means 90A, the number detecting means 90B, etc., which will be described later.

As shown in FIG. 6, the keyboard 102 has a data input key group 104, a space key 106, a development key 108, and the like. Data input by the data input key group 104 and messages indicating other driving conditions are displayed on the liquid crystal display panel 110. It is displayed as appropriate.

The CPU 90 outputs a signal for selectively causing each pixel of the line LED 86 to emit light via the output interface 98 according to a predetermined operation program stored in the ROM 92. Based on this output, the drive circuit 112 causes each pixel to selectively emit light,
Predetermined data is imprinted at a predetermined position on the film 34.

The imprinted data can be, for example, the data shown in FIG. 7 to be inserted in the leading portion and the trailing portion of the film 34. The date can be input by pressing a "date" key in the data input keys 104. In the case of printing a bill, a bank code, a branch code and the like can be automatically input together with the bill. The time can be commanded by pressing the "Date" key while holding down the "Shift" key. When the "start" key is pressed, it is possible to instruct to record "start" in capital letters in the center of the width of the film 34. In addition, "commercial bills" and "other store tickets" registered in advance using the "A" to "J" keys and the "shift" key
Registered characters such as can be specified. By pressing the "confirm" key after these commands are completed, the imprinting operation starts. After the photographing of the document 14 is completed, if the "end" key is pressed and the "confirmation" key is pressed, the recording in uppercase can be instructed. The data to be recorded may be a blip 114 to be recorded outside the frame of the photographed front and back images 14A and 14B.

The "space" key 106 is used when the film 34 is fed in the air without shooting. The "develop" key 108 is pressed after the photographing is completed, so that the film 34
Is cut by the cutter 62 to start development.

Next, the imprinting of a mark indicating a jam (jam mark) will be described. When the document 14 is jammed in the conveyance path, the output of the document sensor 32 does not change. CPU9 in Figure 1
0 has a function of the jam detecting means 90A, and this means 90A monitors the change time of the output signal of the sensor 32, and when the change time interval becomes longer than a certain value, it is judged that the document 14 is jammed, that is, jam. Further, the CPU 90 counts the output of the sensor 32 and obtains the number of shots.
It also has the function of.

When the jam detecting means 90A detects a jam, the control means 88 prints the jam mark M and the number of shots N at this time on the film 34 (FIG. 8).

(Operation) Next, the overall operation of this embodiment will be described with reference to FIG. First, necessary data is transferred to the head of the film 34 or a desired position prior to the photographing of the document 14. The imprinting is performed by inputting data to be recorded from the keyboard 102 with the film 34 stationary at the position where the imprinting is desired (FIG. 9, step 200), and after confirming the data on the data display panel 110, "" Key is pressed (step 202). That is, the feeding of the film 34 starts, and the line LED 86 selectively emits light (step 204).

After the data such as predetermined characters and numbers are imprinted, if you stack the original 14 and set it on the auto feeder 10, the original 14
Are sent out one by one from the top, and the leading edge of the
Detected at 32. After a time set by the timer after the detection, the shutter 50 is opened, and the front and back images 14A and 14B 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 operation is continuously performed to wind the filmed film 34 on the spool 60 (step 20).
6). When the photographing of the predetermined amount of original 14 is completed (step 208)
If the "end" key is pressed and then the "confirm" key is pressed, the character "end" is enlarged (step 210, see FIG. 7).

When the jam detecting means 90A detects a jam during shooting (step 212), the control means 88 stops the feeding of the film 34 (step 214). And again film 3
4 is sent, and the "jam" mark and the "nth sheet" indicating the number n of shots that have been taken without jamming are printed from the light emitting means 86 (step 216), and the feeding of the film 34 is stopped. Let If the operator puts the originals 14 into the auto feeder 10 again without changing the order from the beginning (step 21
8), the control means 88 feeds up to the nth original 14 immediately before the jam occurs, and starts photographing again from the (n + 1) th original (step 220).

If you press the "Develop" key 108 after shooting is completed, the cutter 62
Cuts film 34. This cut end is spool 60
Driven roller 72 of the belt 68
The belt 68 rotates the disk 66 by 180 ° from the side to the disk 66 side, and the spool 60 is switched right and left. Then driven roller
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 unit 74. The developed film 34 is dried and guided to the tray 82.

In this embodiment, the number of images taken up to the place where the jam occurs together with the jam mark is also imprinted, but the present invention can achieve the intended purpose by imprinting only the former. Further, the sensor 32 for detecting a jam also serves as a sensor for the number of shots, but it goes without saying that both sensors may be separate.

It is desirable that the jam mark is represented by characters of a size that can be read with the naked eye, but as a mark different from the blip 114 at the same position as the blip 114 shown in FIG. You may make it imprint.

(Effects of the Invention) As described above, according to the present invention, the jam of the original is detected and the jam mark is printed on the film. Therefore, when the film after development is viewed, it is easy to find the place where the jam occurs from the jam mark. Therefore, it is possible to easily determine that the abnormality of the image captured on the film is caused by a jam.

Here, the jam detecting means has a simple structure if the jam is detected from the passage time of the document, and it is convenient to count the number of shot images by using the signal of the passage time. 2), (4)).

If the film is wrapped around a shooting roller to capture an image of the original, and the jam is also printed on the shooting roller, the length of the running path of the film can be shortened, which is suitable for downsizing of the apparatus (claim (3)).

Also, the number of shots is stored in memory, and when a document is reloaded from the beginning when a jam occurs, the originals are fed up to or near this number of shots, and shooting is performed from the jammed document or a document just before that. If it is continued, the operation becomes simple (claims (5) and (6)).
