Thus, the traveling distance of the film can be made short and the camera is miniaturized. Besides, the assemblage thereof is facilitated and the number of parts is reduced.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a data imprinting device applied to a rotary camera that photographs an original and a film while moving them in opposite directions.

(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, it has been considered to imprint various data such as date, time, photographic content, etc. onto the film. Conventionally, this data has been imprinted by holding the back of the film in contact with a flat back plate and focusing the light from the 8-segment light emitting elements on the film. That is, the film passing between the back plate and the light-emitting element was temporarily stopped, and the light-emitting element emitted light to imprint numbers and the like.

However, in this conventional device, since the film is fixed against the back plate, it is necessary to increase the travel distance of the film by the size of the back plate. This poses a problem in that it becomes an obstacle to downsizing the device, makes assembly troublesome, and increases the number of parts.

(Object of the Invention) The present invention was made in view of the above circumstances, and provides a data imprinting device for a rotary camera that is suitable for downsizing the device, improves assembly efficiency, and reduces the number of parts. The purpose is to

(Structure of the Invention) According to the present invention, it is an object of the present invention to provide a microfilm rotary camera that photographs an original and a film while moving them in opposite directions. A photographic lens that forms and photographs a reduced projected image of the document within a range that comes into close contact with the roller, and a one-dimensional light emitting device that is disposed oppositely within the range that the film of the photographic roller comes into close contact with and that imprints data onto the traveling film. means, a keyboard for inputting data to be imprinted, and control means for selectively causing each pixel of the -dimensional light emitting means to emit light in synchronization with the advance of the film in accordance with the input data. This is achieved by a rotary camera data imprinting device.

(Operation) Data input from the keyboard is stored in the control means, and the control means selectively blinks each pixel of the one-dimensional light emitting means in accordance with this data. Since the film is running at a constant speed during this blinking operation, predetermined data is imprinted on the film.

(Example) Fig. 1 is a conceptual diagram of an embodiment of the present invention, Fig. 2 is a perspective view showing an actual optical system, Fig. 3 is an enlarged view of its main parts, and Fig. 4 shows the document feeding mechanism. 5 is a front view showing the film feeding path, FIG. 6 is a view showing the keyboard, and FIG. 7 is a front view showing the film feeding path.
The figure shows an example of imprinting on film.

First, the outline of the document feeding mechanism 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 accumulated in this stacker 3° in the order in which they are imaged. Here, the original 14 is photographed while passing between the photographing glasses 24 and 24, and the front and rear ends of the original 14 entering the glass are detected by the original detection sensor 32. That is, a light emitting element 34 such as an LED is arranged to face a sensor 32 across the path of the original 14, and the sensor 32 detects passage of the original 14 by intermittent light emitted by the original 14.

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 outside the mirror glass 24, 24, and the images of the front and back screens of the original 14 are formed by mirrors 38a, b, respectively. 40, 42. Photographic 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 due to 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 machine shadow roller 56, a guide roller 58, and the like. 62 is this spool 6
It is a cutter placed in front of o, and is a developing 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 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 the driven roller 72 is moved toward the spool 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 that has been photographed 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 swapped, the driven roller 72 moves toward the spool 60 again and rotates the spool 6o 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, and a washing tank 76C1.
76D. The machined 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 made integrally and can be moved up and down, and by lowering them, the tanks 76A and -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 photographing roller 56,
In the range where the film 34 is in close contact with the machine shadow roller 56, that is, within the upper half circumferential surface of the machine shadow roller 56,
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 is controlled by the CPU 90.
, ROM92, RAM94, input interface (I
F) 96, comprising an earth power 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 an input interface 98.
It is stored in RAM 94° as necessary. Further, data to be imprinted on the film 34 is input from the keyboard 102.

As shown in FIG. 6, the keyboard 102 has a data input key group 104, a space key 106, a development key 108, etc., and data input using the data input key group 104 and messages indicating other operating conditions are displayed on a liquid crystal display board 110. 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, as shown in FIG. The date can be input by pressing the "r 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 r
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. In addition, the rAJ~rJ” key and the “
You can use the ``shift'' key to 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 photographing of the original 14 is completed, by pressing the "end" key and the "confirm" key, the user can command recording in the capital letters. The data to be recorded is the photographed front and back images 14A
, 14B may be recorded outside the frame.

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

(Operation) Next, the overall operation of this embodiment will be explained. First, prior to photographing the document 14, necessary data is imprinted onto the beginning of the film 34 or at a desired position. Imprinting is started by inputting the data to be recorded from the keyboard 102 with the film 34 stationary at the desired imprinting position, checking it on the data display panel 110, and pressing the "Confirm" key. That is, the film 34 starts to be fed, and the line LED 86 selectively emits light.

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 the photographed film 34 onto the spool 60. When the manipulation of a predetermined amount of manuscript 14 is completed, "End" is displayed.
If you press the key and then press the "confirm" key, the word "end" will be printed in large size.

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', and the spool 60 is swapped left and right. Thereafter, the driven roller 72 returns to the spool 60 side, rotates the spool 60 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.

The one-dimensional light emitting means used in this invention is a line LED86.
For example, a one-dimensional liquid crystal shutter in which minute liquid crystal shutters are arranged in a row between the light source and the film 34 can also be used.

(Effects of the Invention) As described above, the present invention not only forms an original image on a photographing roller around which a film is wound and photographs it, but also forms a one-dimensional image so as to face the film at the position where it is wound around the photographing roller. Since a light emitting means is provided and necessary data such as the date is imprinted on the film while the film is being fed, a back plate for holding the film is not required. This makes it possible to shorten the distance the film travels,
The device can be made smaller. Furthermore, since a back plate is not required, assembly becomes easier and the number of parts can be reduced.
