Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a film carrier having a curl correction function, which is used when printing is performed using a developed film wound and stored in a cartridge.

[0002]

2. Description of the Related Art In recent years, in addition to recording an image on a photographic film, a magnetic recording medium or a memory device is provided in a photographic film or a cartridge for storing the photographic film to record photographing information, print information, and user identification information. Has been proposed (for example, JP-A-62-103625, JP-A-6-103625).
No. 2-208028, JP-A Nos. 1-279231 and 1
-289948). In this way, when other information is recorded together with the image and is intended to be used at the time of printing, if the film is returned to the customer in the form of a film piece that is cut every 4 to 6 frames as in the conventional case,
The various information may be divided, and the recording of the various information cannot be effectively used at the time of the next additional print. Therefore, it has been proposed to wind up and store one order in a cartridge without cutting the film after simultaneous printing into film pieces (for example, JP-A-1-279250 and 2-9519).
Publication).

[0003]

By the way, in order to reduce the storage space of the developed film, it is effective to wind the film on a thin spool, but it is effective to use a conventional triacetyl cellulose (TAC) as a base. The film has a strong curl during storage, and the flatness of the film may be deteriorated during reprinting such as additional printing, which may lead to deterioration of print quality and trouble of running of the film. On the other hand, as a method of improving the flatness of a film having a strong curl at the time of printing, a method of sandwiching with glass is used. In this case, Newton's ring is easily generated, dust is easily attached, and the screen position is changed. There are drawbacks such as difficulty in matching and poor workability.

The present invention has been made to solve the above problems, and provides a film carrier with a curl correction function, which enables a film having a curl to be printed and exposed without being sandwiched by glass. With the goal.

[0005]

In order to achieve the above object, the present invention provides a means for pulling out a film from a photographic film cartridge in which a developed film is wound and stored, and a state in which the pulled out film is stored. A means for removing the curl by winding the film upside down, a means for intermittently transferring the drawn film in the storage direction in the cartridge for printing, and a means for winding the transferred film into the photographic film cartridge. From the film carrier.

[0006]

The film which has been ejected from the cartridge is taken up by the take-up shaft arranged in the film carrier after passing through the exposure opening, in the opposite direction to the state in which it is stored in the cartridge. In this way, since the film is wound upside down, the curl of the film is corrected. At the time of winding, various information such as photographing information and print instruction information is read from the magnetic recording layer of the film. After all the film is wound on the winding shaft on the side of the film carrier, the film is wound and stored in the film cartridge. At the time of winding, each frame recorded on the film is sequentially set in the exposure opening, and each frame is printed and exposed on the color paper based on the photographing information and the like.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIG. 2, a printed negative film 10 returned to a user after simultaneous printing is wound and stored on a spool 12 in a cartridge body 11. The photographic film cartridge 13 has a function of moving the spool 12 in the feeding direction opposite to the film winding direction so that the leading end 10a of the film comes out from the film entrance / exit 14 of the cartridge main body 11 to find the film. Therefore, the cartridge body 1
The film storage chamber 15 of No. 1 is formed to have a size which is almost the same as or slightly larger than the maximum winding diameter of the film 10 when the film 10 is completely wound on the spool 12, and the film 10 when the spool 12 is rotated in the feeding direction. Prevents the roll from unraveling. As a result, the rotation of the spool 12 can be transmitted to the film leading end 10a, and the film leading end 10a can be discharged to the outside from the film entrance / exit 14.

Further, the film tip portion 10a is rounded and round-cut, so that the film feeding resistance at the time of the film cueing is reduced. A perforation 10b for feeding the leading end of the film is formed on the leading end 10a. Further, a positioning perforation 10d is formed in each frame 10e in the image recording portion 10c, and the perforation 10d is mechanically or optically detected to expose the frame of the camera or the film carrier of the printer. Each frame 10e of the film is sequentially set to and an image is recorded. A transparent magnetic recording layer is formed over the entire surface of the film on the side opposite to the emulsion side of the film, and the film information, photographing information, print instruction information, exposure correction information, etc. are formed on the film. Magnetically recorded at the time of manufacturing, photographing, printing, etc. Instead of the transparent magnetic recording layer, a track-shaped magnetic recording layer long in the film carrier feeding direction may be provided at a position where each frame 10e is removed.

The printed film 10 having the above-described structure is wound up and housed in the cartridge main body 13 and is delivered to the user together with the finished print. When ordering reprint prints, this photographic film cartridge 13 is submitted to the photo lab. At the developing station, a printer processor as shown in FIG. 1 is used to perform additional printing. As is well known for printer processors,
A film carrier 16, a print exposure unit 17, a paper transport unit 18, and a paper processor unit 19 are provided.

The photographic film cartridge 13 to be reprinted is a film carrier 16 embodying the present invention.
Is set to. As shown in FIG. 3, the film carrier main body 21 is provided with a film transfer path 22 as is well known, and an exposure opening 23 is provided in the center thereof. A film holding frame 24 is attached by a mounting shaft 25 to the rear center of the film carrier body 21 so as to be openable and closable. This film holding frame 24

The carrier mask is in a state of being retracted from the film at the time of transferring the film, and the solenoid 10 presses the film 10 against the carrier body 21 side at the time of printing.

A cartridge storage recess 30 is formed in the film transfer path 22a on the film entrance side of the exposure opening 23. The photographic film cartridge 13 is stored in the cartridge storage recess 30. As shown in FIG.
A spool rotation shaft 31 that engages with the shaft end of the spool 12 of the stored cartridge 13 and rotates the spool is provided in the storage recess 30. The spool rotating shaft 31 is movable in the axial direction by a shift portion 32 so that the spool 13 does not retract from the storage recess 30 when the cartridge 13 is not housed and does not hinder the insertion of the cartridge 13 into the recess. .. A motor 35 is attached to the spool rotary shaft 31.
Is connected, and the forward and reverse rotations thereof cause the spool rotation shaft 31 to rotate the spool 12 in the film feeding direction or in the film winding direction opposite thereto.

Further, as shown in FIG. 3, a film winding section 40 is provided on the film pressing frame 24 at a position corresponding to the film transfer path 22b on the film exit side.
The film winding section 40 is provided with the cartridge storage recess 30.
The inside of the cartridge 13 is set in such a manner that the cartridge 13 is set inside and the film is in a reverse direction. The film winding unit 40 is composed of a winding shaft 41 and a film guide piece 42, like the film winding unit of the camera. The guide piece 42 guides the fed film leading end portion 10a to the winding shaft 41, and locks the film feeding perforation 10b of the film leading end portion 10a on the claw of the winding shaft 41, whereby the film leading end portion 1a.
0a is wound around the winding shaft 41. The drive of the winding shaft 41 is transmitted from the winding shaft motor 43 on the carrier base side via the gear 44, but instead of this, the winding shaft motor may be arranged in the film pressing frame 24. ..

As shown in FIG. 2, the film 10 which has been fed from the cartridge 13 by the rotation of the spool rotary shaft 31 in the feeding direction is pulled out from the cartridge 13 by the film feed roller pair 45. At the film exit side of the film feed roller pair 45, the film tip portion 10a is provided.
A film sensor 46 for detecting The film sensor 46 is composed of a photosensor of a light emitting and receiving type. After the film sensor 46 detects the film tip portion 10a, the spool rotation shaft 31 is brought into a free state, and thereafter, the film 10 is pulled out by the rotation of the film feed roller pair 45. Further, a magnetic head 47 for reading various recording information recorded on the magnetic recording layer of the film 10 is arranged next to the film sensor 46. A read signal from the magnetic head 47 is converted by the decoder 48 into various kinds of recording information, which are, as shown in FIG. 1, a controller 50 of the printer and an exposure amount calculator 57.
Sent to. Further, the holding frame 2 of the film carrier 16
In addition to the film sensor 46 and the magnetic head 47, a perforation sensor 51 is provided in the unit 4.
Based on this perforation detection signal, each frame to be printed is set in the exposure opening 23.

Further, as shown in FIG. 1, a photometric scanner 55 is arranged in the printer at a position facing the exposure opening 23 of the film carrier 16. As is well known, the photometric scanner 55 is composed of an image area sensor and the like, performs three-color separated photometry on the image at each point of the frame to be printed, and sends this photometric signal to the characteristic value calculation unit 56. The characteristic value calculation unit 56 calculates a characteristic value necessary for determining the printing exposure amount and sends it to the exposure amount calculation unit 57. The exposure amount calculation unit 57 calculates the printing exposure amount based on the characteristic value and various recording information from the decoder 48, and sends this to the controller 50.

Below the film carrier 16, a light source 6 is provided.
0, a filter drive unit 61, and a diffusion unit 62 are arranged. The filter driving unit 61 inserts a cyan filter 61a, a magenta filter 61b, and a yellow filter 61c in the optical axis of printing, and adjusts the light quality of the light source 60 based on the printing exposure amount. The diffusing portion 62 uniformly diffuses the dimmed printing light. A zoom lens 63 and a shutter 64 are arranged on the film carrier 16. The zoom lens 63 forms an image of a frame to be printed on the color paper 65.

The color paper 65 is wound into a roll and set at the print position by a pair of paper feed rollers 66 and 67. Then, the baking-exposed paper 65 is sent to the paper process unit 19, where it is developed, and then cut by the cutter into each frame,
It is discharged to the stacking unit 69.

The controller 50 determines each frame position data based on the detection signal of each perforation and the film feed amount, and stores this position data in the memory 71 in the controller 50 as the perforation count number as search data. .. Further, the controller 50 is
The set position of each color filter is calculated based on the printing exposure amount, and this is stored in the memory 71 in association with the frame position data. Further, the controller 50 determines the focal length of the photographing lens based on the pseudo zoom information of the recorded information,
This is similarly stored in the memory 71. Further, the controller 50 displays a command input from the keyboard 72 and various information from the decoder on the display 73. Then, when the film 10 is wound so as to be housed in the cartridge 13, each print target frame is positioned in the exposure opening 23 of the film carrier 16 using each position data, and the film is determined at the time of photometry. The filter drive unit 61 is controlled so that the set position is reached, and the printing exposure is performed. Further, in the case of pseudo zoom printing, the focal length of the zoom lens 63 is adjusted so as to obtain a predetermined print magnification. The method for determining the printing exposure amount based on the above-mentioned recorded information is described in detail in Japanese Patent Application No. 2-233573. The creation of the pseudo zoom print is described in detail in Japanese Patent Application No. 1-268523.

Next, the operation of this embodiment will be described with reference to FIGS. 4 and 5. First, the film cartridge 13 to be printed is set in the cartridge storage recess 30. When this set is detected by a sensor or the like, the controller 50 controls the shift unit 32 to insert the spool rotation shaft 31 into the shaft end of the spool 12 and then reverse the motor 35 to move the spool 12 in the film feeding direction. Rotate.
As a result, the film tip portion 10a is indexed from the cartridge body 11 (see FIG. 5A). Further, the controller 50 causes the film feeding motor 75 to rotate in the normal direction and rotates the film feeding roller pair 45. When the film leading end portion 10a which has been indexed passes the film sensor 46, the motor 35 stops rotating and the spool 12 is brought into a free state by the detection signal of the film sensor 46. Therefore, after this, the film feed roller pair 45
The film 10 is pulled out from the cartridge main body 11 by the rotation of. Further, the controller 50 causes the winding shaft motor 43 to rotate in the normal direction, and rotates the winding shaft 41 in the winding direction. As a result, the film tip portion 10a is moved to the guide piece 42
Is guided by the winding shaft 41 and is wound by the winding shaft 41.

As shown in FIG. 5B, this film 1
The magnetic head 47 reads the photographing information, the film information, and the print instruction information recorded on the transparent magnetic recording layer of the film 10 during the winding by the winding shaft 41 of 0. Decoder 48
Converts the read signal from the magnetic head 47 into various recording information and sends it to the exposure amount calculation unit 57 and the controller 50. Further, the scanner 55 measures the print target frame set in the exposure opening 23. The exposure amount calculated by the exposure amount calculation unit 57 based on the characteristic value and various recording information is sent to the controller 50, where the set position of each color film is calculated for each frame, and this is stored in the memory 71 together with the position data. It The memory 71 also stores the print magnification obtained based on the pseudo zooming information and the like. It is also possible to observe the recorded information displayed on the display 73 and, based on this, the operator operates the keyboard 72 to manually input the print data and the like.

In this manner, the frames to be printed are sequentially measured, and the exposure amount of each frame is calculated. When the film 10 is completely pulled out from the cartridge body 11, the perforation sensor 51 detects the film end mark. The film end mark is formed by arranging two positioning perforations 10e, for example. In addition to this, since the cartridge is displaced in the film transfer direction at the film end, the film end may be detected by detecting this displacement amount and further by detecting an increase in the transfer load.

After the film end is detected, as shown in FIG. 5 (C), the film 10 is transferred in the reverse direction, and the film 10 is wound into the cartridge body 11. Then, when the last frame is set in the exposure opening 23, the transfer of the film 10 is stopped. After that, the filter driving unit 61 and the shutter driving unit 74 operate to print the image of this frame on the color paper 65 based on the predetermined printing exposure amount. After printing, the frame is advanced by one frame, and the printed frame is transferred in the cartridge direction. As described above, the film 10 is wound around the winding shaft 41, and the winding direction is opposite to the state in which the film 10 is stored in the cartridge 13 so that the film 10 is not stored. Is wound so as to curl to the opposite side, so that the curl of the film 10 is corrected. Therefore, even if the film 10 is wound up and stored in the cartridge 13, the curl is corrected, so that the flatness is secured at the exposure position of the film carrier 16 by simply pressing the four circumferences of the film 10. .. Since the curling habit is corrected in this manner, it is not necessary to press the frame to be printed with the glass plate or the like to flatten the film, and it is possible to prevent the generation of Newton's rings or the like that occurs when the glass plate is used. ..

The color paper 52 that has been exposed by printing is developed in the processor unit 19, cut into each frame, and then discharged to the stacking unit 69. Further, when the reprint printing for one order is completed, the film sensor 46 detects the film tip portion 10a, and a predetermined time (time until the film tip portion 10a is completely stored in the cartridge main body 11) elapses after the detection. After that, each motor is stopped.
After that, the next photographic film cartridge 13 is set in the cartridge accommodating recess 30, and additional printing is performed in the same manner.

In the present embodiment, photometry is performed on each frame in the forward path in which the film 10 is wound around the winding shaft 41 to correct the curl, and subsequently, the characteristic value and the exposure amount are calculated in advance, Since the calculation of the characteristic value and the exposure amount that require a relatively long calculation time is completed in advance, only printing can be performed at the time of printing, and the overall printing time can be shortened. In this embodiment, the image area sensor is used for surface photometry, but in addition to this, a line sensor or the like is used to measure the frame for printing by sub-scanning the film feed. May be. Further, when the film is wound around the winding shaft 41, various recording information may be simply read, and photometry and printing may be performed in the returning path. Also,
When printing a normal 135 type film or the like, the guide piece 42 is retracted into the holding frame 24, and a guide piece that covers the opening of the storage recess 30 is provided. When the cartridge is stored, the guide piece is retracted into the recess 30 in conjunction with the storage, and the cartridge is recessed in the recess 30.
It is preferable to be configured to return to a position that covers the opening of the recess 30 when taken out from.

Further, in the above-mentioned embodiment, the case of additional printing is explained as an example, but in addition to this, when the photographed film is wound up and stored in the cartridge after the development processing and printing is performed using the film. Also, the present invention can be implemented. Further, in the case of the type in which the film cartridge 13 is set upside down in the above-mentioned embodiment and is set in the accommodating concave portion, the film carrier main body 21 is provided with a take-up shaft, and the film is wound in the opposite direction to the accommodating direction. Take
Similarly, the curl of the film can be corrected.

[0025]

As described above, according to the present invention,
The curl of the film wound and stored in the film cartridge can be removed with a simple structure. This makes it possible to print by simply pressing the four circumferences of the film, unlike printing by sandwiching it between glass, etc., so there is no inconvenience caused by the use of glass such as Newton's rings or dust being noticeable. The quality can be improved. Furthermore, since the traveling problem of the film due to the curl is eliminated, the film can be fed reliably. Further, even a film having a curl can be continuously processed automatically, so that a high processing capacity can be achieved.
