BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a photographic film cartridge for storing a long photographic film such as a developed negative film.

0002

2. Description of the Related Art In order to obtain a print from a negative film on which an image has been taken by a camera, a customer generally takes the negative film to a photo agency and requests that it be developed and printed (reprints). Negative film brought to a photo agency is developed and printed at a photo processing laboratory (laboratory).
Photo processing such as reprinting is performed.

That is, at a photo agency, the photographed negative film is stored in a DP bag with the details of the customer's order written on it and transported to a photo processing facility.
The photographed negative film is developed and printed according to the order details written on the P bag. The developed negative film is cut into several frames and stored in a negative sheet, and after being compared with the finished print, it is put back into the DP bag and returned to the photo agency, where it is handed to the customer.

[0004] In order to process a large number of negative films requested by a plurality of different photo agencies and customers at a photo processing facility, a series of processes are carried out while always matching the negative films and DP bags. Must. For this reason, in the past, ID stickers with ID codes printed on them to identify photo distributors and customers were attached to negative film and DP bags, and the ID stickers (ID codes) were read during a series of processing steps. As a result, the negative film and the DP bag were processed in correspondence with each other.

[0005] Therefore, the complicated work of pasting ID stickers onto individual negative films and DP bags is indispensable, which is extremely inefficient, and a countermeasure for this problem has been desperately needed. Furthermore, as mentioned above, the developed negative film is cut every few frames and stored in the negative sheet, so handling operations such as taking it out of the negative sheet and storing it again during the reprinting process are required. not easy,
It is difficult to respond.

Therefore, without cutting the developed negative film every few frames, it is rolled up again into layers and stored in a container, and during subsequent processing (when reprinting or returning to the customer), The present applicant has proposed a photo processing system that transports and handles this storage container (Patent Application No.
No. 84017).

[0007]

[Problems to be Solved by the Invention] In this case, a simple container equipped with a rotatable spool such as a general cartridge cannot be used as a container for storing the negative film by rewinding it into layers without cutting it. It is difficult to easily and reliably roll up and store it.

Further, the other end of the sorting device 40 is provided with a cartridge pocket portion 52 into which a cartridge 10 containing a negative film 20 is inserted and processed by a cartridge 50 or a developing device 42 to be described later. A film stocker section 54 is arranged on the side of the cartridge pocket section 52. The film stocker section 54 stores the negative film 20 (patrone 50 or cartridge 10) in a box-shaped film stocker 56 after sorting the negative film 20 (patrone 50 or cartridge 10) into simultaneous printing and reorder (reprint) printing based on order conditions. Can be done. This film stocker 56 can store a plurality (for example, 20 to 30) of cartridges 50 or cartridges 10 at one time. Also, corresponding to the negative films 20 sorted into the film stocker 56, the D
The DP bags 46 are sorted in the P bag stock section 48.

The developing device 42 has a general mechanism for developing the negative film 20, and stores cartridges 50 (undeveloped negative films 20) sorted by the sorting device 40 at one end. The film stocker 56 can be set. The developing device 42 can pull out the undeveloped negative film 20 from the set film stocker 56 and perform a developing process. Also,
The developing device 42 has a built-in cartridge winding section, and the developed negative film 20 is transferred to the cartridge 10.
It can be rolled up and stored. Furthermore, a film stocker 56 containing an empty cartridge 10 is set at the other end of the developing device 42, and the negative film 20 after development can be wound around the cartridge 10.

The printing verification device 44 has an exposure/printing section 58 and a developing section 60 for printing and exposing the negative film 20 and developing the photographic paper, and takes out the cartridge 10 from the film stocker 56 in which it is set. At the same time, the negative film 20 is sequentially pulled out and subjected to printing and development processing to produce a print 62.

Next, the operation of this embodiment will be explained in order according to the processing steps of the photographic processing system. The negative film 20 (patrone 50) on which the image has been exposed by the camera is brought to a photo agency. At the photo agency, a cartridge 50 (negative film 20 that has been photographed) is stored in a DP bag 46 in which the customer's order details are written and transported to a photo processing facility. Further, when the customer reorders (reprints) the print 62, the cartridge 10 containing the corresponding negative film 20 is stored in the DP bag 46.

In the photo processing facility, the sorting device 40 is equipped with DP bags 46 and cartridges 50 (or cartridges 1
0) is set. In the sorting device 40, cartridges 50 or cartridges 10 are sorted into simultaneous printing and reorder (reprint) printing based on order conditions, and then stored in film stockers 56, respectively. Further, the DP bags 46 are sorted accordingly.

Among the cartridges 50 or cartridges 10 sorted according to subsequent processing and stored in the film stocker 56, the film stocker 56 storing the cartridge 50 (that is, the undeveloped negative film 20) is sent to the developing device 42. It will be done. In the developing device 42,
From the set film stocker 56 to cartridge 5
At the same time, undeveloped negative films 20 are taken out and developed one after another. The developed negative film 20 is wound up into the cartridge 10 and further stored in the film stocker 56.

is exposed (as shown in FIG. 3). Next, the front lid 26 is rotated approximately 270 degrees around the support shaft 28, and as the front lid 26 rotates, the auxiliary lid 30 is relatively rotated to be in a straight line along the front lid 26. As a result, the front cover 26 and the auxiliary cover 30
is spanned between the insertion port 14 and the spool 18 (as shown in FIGS. 1 and 4). Therefore, the negative film 20 inserted through the insertion opening 14 is guided to the spool 18 by the front cover 26 and the auxiliary cover 30, is smoothly inserted toward the spool 18, is securely locked, and is wound up.

are extracted and printed to produce individual prints 62. Next, each print 62 is inspected, and the prints 62 that pass the test are stored in a DP bag 46 together with the cartridge 10 containing the negative film 20, and transported to a photo agency and handed to a customer.

On the other hand, prints 62 that are rejected as a result of the inspection and verification are sent back to the sorting device 40 together with the negative film 20 and cartridge 10, and the printing conditions (exposure correction information, etc.) are corrected and the above-mentioned process is repeated. Repeated.

As described above, since the cartridge 10 according to this embodiment includes the front cover 26 and the auxiliary cover 30,
The negative film 20 can be easily and reliably wound up and stored.

Next, another embodiment of the present invention will be described. Note that parts that are basically the same as those in the first embodiment are given the same reference numerals as in the first embodiment, and their explanations are omitted.

FIGS. 6 and 7 show side views of a photographic film cartridge 70 according to a second embodiment.

In the cartridge 70, an oblong support hole 76 is formed in the opposing side wall 74 of the main body 72, with its longitudinal axis extending in the vertical direction of the main body 72, and a spool 78 is extended over the support hole 76. It is rotatably supported. Therefore, the spool 78 is movable in the vertical direction of the main body 72 along the support hole 76.

The upper lid 82 as a lid attached to the insertion port 80 of the main body 72 can close or open the insertion port 80 by sliding along the width direction of the main body 72. . When the upper lid 82 is slid and the insertion port 80 is opened, the spool 78 inside the main body 72 is exposed.

The front cover 84 has a support shaft 86 on the side of the upper cover 82.
installed by. The front lid 84 has a negative film 20 ejection port 88 formed on the side wall of the main body 72.
This outlet 88 can be closed in response to the
By rotating around 6, the take-out opening 88 is opened, and the negative film 20 can be pulled out from inside the main body 72.

On the other hand, a cam 90 constituting interlocking means is arranged below the spool 78, and an intermediate roll 92 is arranged between the cam 90 and the spool 78 so as to be in contact with both. Therefore, when the cam 90 rotates, the spool 78 is pushed up via the intermediate roll 92,
It can be moved upwardly along the support hole 76. A gear 94 is coaxially and integrally fixed to the axis of the cam 90, and furthermore, the gear 94 meshes with a gear 96 disposed near the cam 90 and also constituting interlocking means. Below the gear 96 is a rack 98 that also constitutes interlocking means.
is arranged and meshes with the gear 96. The rack 98 is movable along the width direction of the main body 72, and can rotate the gear 96 by moving along the axis. One end of a link rod 100 bent in an L-shape and also constituting interlocking means is fixed to one end of the rack 98, and the intermediate portion of the link rod 100 extends toward the top of the main body 72. The other end is fixed to the above-mentioned upper lid 82. Therefore, when the upper lid 82 slides, this is transmitted to the rack 98 via the link rod 100, and the rack 98 is moved integrally with the upper lid 82 in the same direction.

In this cartridge 70, when the upper cover 82 slides in the direction of opening the insertion port 80, the rack 98 is moved in conjunction with this, and the gears 96 and 94 are moved.
The cam 90 is rotated via. For this reason, spool 7
8 is pushed up and moved upward along the support hole 76 to approach the insertion port 80. Therefore, the negative film 20 inserted through the insertion opening 80 is easily engaged with the spool 78, and is reliably wound up and stored.

As described above, in the cartridge 70 according to this embodiment, the spool 7 is opened in conjunction with the opening movement of the upper lid 82.
8 is brought close to the insertion opening 80, so that the negative film 20 can be easily and reliably wound up and stored.

[0040] In this embodiment, the interlocking means is composed of the link rod 100, the rack 98, the cam 90, etc., but the present invention is not limited to this, and other compositions may be used. For example, as shown in FIGS. 8 and 9, the edge of the upper lid 82 may be bent at a substantially right angle and extended along the side wall of the main body 72 to form an arm portion 102 as an interlocking means. An oval cam hole 104 whose longitudinal axis is inclined with respect to the support hole 76 of the main body 72 is formed in the arm portion 102 . An end portion of a spool 78 inserted into and supported by the support hole 76 is movably inserted into the cam hole 104 . Therefore, when the upper lid 82 slides in the direction of opening the insertion port 80, the spool 78 moves into the cam hole 104.
It is configured such that it is pushed upward along the support hole 76 while being pressed by the peripheral edge portion of the support hole 76 .

In this case as well, the spool 78 is connected to the support hole 76.
Since the negative film 20 is moved upward along the insertion opening 80 and approached the insertion opening 80, the negative film 20 inserted through the insertion opening 80 is easily engaged with the spool 78, and is reliably wound up and stored. Furthermore, the mechanism for interlocking the movement of the spool 78 with the movement of the upper lid 82 is also simplified.

Next, FIG. 10 shows a perspective view of a photographic film cartridge 110 according to a third embodiment.

In the cartridge 110, the spool 114
An insertion opening 116 is provided on the inner periphery of the side wall of the main body 112 that supports the
A guide groove 118 is formed at a position corresponding to . The guide groove 118 is formed along the insertion movement trajectory of the negative film 20 from the insertion opening 116 to the spool 114, and guides the negative film 20 inserted from the insertion opening 116 to the spool 114. .

In this cartridge 110, the insertion port 11
The negative film 20 inserted from 6 is forcibly moved toward the spool 114 while being guided by the guide groove 118. Therefore, it is reliably locked onto the spool 114, wound up, and stored.
