Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




The present invention relates to film processing and, particularly, to a slot coater system and method of operation.




2. Description of the Related Art




In developing photographic film, a number of processing solutions are generally used to develop and stabilize the image on the photographic film. One such method for developing photographic film is traditional chemical film development. The traditional chemical film development process generally includes the steps of developing, stopping, fixing, clearing, washing, drying, and sealant. With the exception of drying, each of these processing steps generally requires the application of a different processing solution to the film. The processing solutions are generally applied to the film by showering or dipping the film in different containers of processing solutions. The used processing solutions are often hazardous chemicals and their disposal is regulated by government agencies.




A relatively new photographic film processing method is digital film development. Digital film development is a method of electronically digitizing the images stored on the film during the film development process. In electronic development, the electronic digitizing process involves scanning the film through the processing solution. In other words, when the image on the film is scanned, the film is still wet with processing solutions. As a result, it is desirable to uniformly apply the processing solution to the film.




Conventional methods have the disadvantage of failing to provide a uniform application of processing solutions. Another disadvantage of conventional processes is the requirement for disposal of used and excess processing solutions.




SUMMARY OF THE INVENTION




These and other drawbacks are overcome in large part by a system and method according to the present invention. Briefly summarized, a slot coater system and method of operation are provided for applying processing solutions to film. In one embodiment of the present invention, a slot coater is provided. In this embodiment, the slot coater includes a housing having an opening for dispensing a processing solution, a reservoir within the housing adapted to provide a substantially uniform pressure across the width of the housing, and a channel for delivering the processing solution from the reservoir to the opening. According to a particular embodiment, the slot coater is formed as a replaceable cartridge.




In another embodiment of the present invention, a film processing system is provided. In this embodiment, the film processing system comprises a delivery system that includes a slot coater operable to apply a processing solution to film. In a particular embodiment, the film processing system further comprises an imaging station operable to digitize an image on the film.




One or more embodiments of the invention provide important technical advantages. Various embodiments of the invention may have none, some, or all of these advantages. For example, in some embodiments, the slot coater has the advantage of applying a substantially uniform coat of processing solutions on the film. Another advantage is that the slot coater uses relatively little processing solution relative to conventional viscous film processing fluid. As such, disposal of excess film processing fluid is not required.

One embodiment of the slot coater head


24


is illustrated in greater detail in

FIGS. 3-5

. According to the embodiment illustrated, the slot coater head


24


includes a housing having an anterior portion


44


and a posterior portion


46


. A shim


48


having predetermined thickness separates the anterior portion


44


and the posterior portion

(

FIGS. 3

,


4


A,


5


C) includes an external face


50


, an internal face


52


, and side surfaces


54


,


56


. The side surfaces


54


,


56


may include beveled portions


58


,


60


respectively, which taper to a predetermined width to the surface


62


. The external face


50


also may include a beveled portion


64


, which tapers to the surface


62


. As will be discussed in greater detail below, the anterior portion


44


may further include a trough or reservoir


66


for holding developer, which is provided via a feed pipe


67


.




The posterior portion


46


(

FIGS. 3

,


4


A,


5


A) includes an external face


68


, an internal face


70


, and side surfaces


72


,


74


. The side surfaces


72


,


74


may include beveled portions


76


,


78


, which taper to the surface


80


, to match the surface


62


of the anterior portion


44


. The external surface


68


may include a beveled portion


82


, which tapers to the flat edge


80


.




The feed pipe or tube


67


may be provided to a hole


84


in the external surface


68


of the posterior portion


46


. As shown, the hole


84


extends through the posterior portion


46


and, with the feed pipe


67


, allows the processing solution


19


to enter the slot coater head


24


at a constant volumetric rate. The processing solution


19


is provided via the hole


84


to the reservoir


66


. The reservoir


66


functions to prevent a pressure gradient across the direction of flow. It is noted that while shown in face


68


, the hole


84


may be provided through any other surface. Similarly, the reservoir


66


may be provided at a variety of locations internally. Moreover, in other embodiments, a reservoir


66


may not be necessary. Thus, the figures are exemplary only.




A series of holes


86


may be provided as screw holes in both the anterior portion


44


and the posterior portion


46


to allow screws (not shown) to secure the anterior portion


44


to the posterior portion


46


and the shim


48


there between.




The shim


48


(

FIG. 5B

) is relatively thin and, when secured between the anterior portion


44


and the posterior portion


46


, provides a sealed channel through which the developer may be applied. The shim


48


includes a base portion


88


and extending members


90


,


92


. The base portion


88


and the extending members


90


,


92


include screw holes to match those of the anterior and posterior portions. It is noted that in some embodiments, a shim is not necessary; the desired gap may be directly formed into the anterior and/or posterior portions. The interior surfaces


94


,


96


of the extending members


90


,


92


, and the interior surface


98


of the base portion


88


, in conjunction with the interior surfaces


52


,


70


, of the anterior portion


44


and the posterior portion


46


, define the channel of width T for the developer. The width T is chosen to allow developer to be applied to the film's emulsion layer.




Further, as seen in

FIG. 4B

, the anterior portion


44


and the posterior portion


46


are separated by the shim (not shown) at a distance t. The slot or channel width t is chosen to optimize the coating process. Finally, the surfaces


62


,


80


of the anterior and posterior portions


44


,


46


are maintained at a gap width


100


, such as 50 to 500 microns, above the film layer


20


. Finally, the slot coater head


24


may be positioned at an angle of about 80-100 degrees with respect to the film surface.




It is noted that in alternate implementations, the slot coater head


24


is applied directly to the surface of the film


17


. In one such alternate implementation, the slot coater head


24


includes a porous material (not shown), such as a felt-like material, a brush-like material, or a plurality of capillaries, occupying at least a portion of the slot. The porous material may be positioned to directly coat the surface of the film


17


. Thus, the figures are exemplary only.

24




b


may be fixed to rotate about axis C.




In the embodiments shown in

FIGS. 6A and 6B

, the slot coater head


24


is formed as a separate unit from the cartridge or syringe pump. In such an embodiment, the slot coater head


24


may typically be formed from metal, plastic, or similar material. In alternate embodiments, however, the slot coater head and the cartridge or pump may be provided as an integrated, replaceable unit. Exemplary slot coater assemblies employing integrated slot coater heads

c


. Finally, it is noted that, while shown in a vertical configuration, the slot coater assembly


22




c


may be provided at various angles from vertical, so long as the angle between the film


17


and the slot coater head


24




c


is maintained to allow delivery of the processing solution


19


.





FIG. 7B

illustrates a similar embodiment, though employing a syringe pump rather than a collapsible cartridge. In particular, the cartridge


102




d


is embodied as a syringe which includes a slot coater head


24




d


integrated therewith. The syringe


102




d


includes a pusher


124




b


for pushing against the processing solution


19


and forcing it out the slot coater head


24




d


. An end of the pusher


124




b


forms a coupler


122




d


which is attachable to a driving member


118




d


, such as a lead screw. The driving member


118




d


and a motor


116




d


together form a driving unit


114




d


. The driving member


118




d


is driven by the motor


116




d


in a manner similar to that described above.




An alternative coupling for the slot coater head to the cartridge and/or syringe pump is shown in FIG.


7


C. In particular, a slot coater head


24




e


may be coupled to the syringe pump or cartridge


102




e


by way of a rigid tube


126


. In any of the embodiments of

FIGS. 7A-C

, the slot coater head


24


may be integrated with the cartridge or syringe in a single manufacturing process. The cartridge and syringe pump may be formed with the slot coater head


24


from injection molded or blow molded plastic.




As noted above, a capping station


30


(

FIG. 1

) may be provided to cap or seal the slot coater head


24


when not in use. Such a capping station


30


is provided to prevent evaporation of the developer or undesirable effects that may result from exposure to air or contaminants. The capping station


30


may also be provided to wipe clean the head of the slot coater


24


and may also be used to provide a reservoir for purging or priming the slot coater.




The capping station


30


may be formed as part of the integrated cartridge(s) described above with reference to

FIGS. 7A-7C

or may form a separate unit. One embodiment of a capping station is shown in FIG.


8


. The capping station


30


includes a receiving portion


128


which may be dimensioned to fit against the slot coater head


24


. In particular, the receiving portion


128


may include beveled portions to match the bevels of the slot coater head


24


. As shown, the slot coater head


24


includes a mounting member


130


for mounting on a support


132


. The capping station's receiving portion


128


also includes a mounting member


134


for mounting. The receiving portion


128


as shown is slidable along support


132


by way of the mounting member


134


and is attached to an actuator (not shown) which may be provided within the digital film processor. The actuator slides the receiving portion


128


into position against the slot coater head


24


when not in use. The receiving portion


128


may also be provided with a reservoir (not shown) for purging or priming the slot coater.




In addition, as discussed above, the slot coater


24


may be fixed to pivot about axis C (

FIG. 6A

,


6


B) by a locating system


28


(FIG.


2


). The locating system


28


then pivots the slot coater head


24


from a position in which it applies processing solution to the film


17


to a position where the capping station's receiving portion


128


may be applied. During rotation, the slot coater head


24


may also be positioned to wipe against the receiving portion


128


, so as to provide a degree of cleaning.




Modern electronic cameras code image information as bar codes along the edge of film, for example, between the edge of the film and the film sprocket holes. Such information may include, for example, frame number and film type, and the like. One way to read this information is by using the slot coater to apply processing solution along the entire surface of the film. To prevent processing solution from leaking through sprocket holes in the film, potentially damaging the imaging system, a leak controller according to an implementation of the invention is provided.




In particular,

FIG. 9A

illustrates a leak controller


136




a


positioned to prevent leakage of developer off the film


17


or to clean such developer that does leak. The leak controller


136




a


may be embodied as any device suitable to either remove or prevent leaks from the film from affecting the transport and imaging system(s).




A particular implementation of a leak controller


136




b


is illustrated in FIG.


9


B. The leak controller


136




b


is implemented as backing material, such as one or more adhesive tapes applied to the film


17


behind the sprocket holes. Alternatively, the backing material may comprise simply a strip of material held in place by surface tension or the transport mechanism.





FIG. 9C

illustrates another approach to leakage control. In particular, the leakage controller


136




c


of

FIG. 9C

includes one ore more sprockets


137




a


-


137




n


having “teeth” that fit within the sprocket holes in the film


17


and thereby prevent the processing solution from leaking through. Sufficient sprockets may be provided for the processing solution


19


to dry enough so that it no longer runs through. A similar approach is shown in the implementation of FIG.


9


D. The leak controller


136




d


is implemented as one or more sprocket belts, again having teeth adapted to fit the sprocket holes of the film


17


and push up processing solution


19


and prevent it from leaking through.





FIGS. 9E and 9F

illustrate leak controllers


136


which employ air to control leakage. In

FIG. 9E

, the leak controller


136




e


is implemented as a blower


138


that is used to dry out the processing solution


19


before it can leak through the sprocket holes. The blower


140


may include a heating element


140


. The leak controller


136




f


of

FIG. 9F

employs one or more suction devices


142




a


-


142




n


to pull the developer through the sprocket holes so that it does not leak through. Any device suitable to create the desired level of suction may be employed.




The leak controller


136




g


of

FIG. 9G

is implemented as one or more flexible or non-flexible squeegee blades


144




a


-


144




n


that are rotated into position against the underside of the film


17


to remove the processing solution


19


as it falls through the sprocket holes. The processing solution


19


is then removed from the squeegee blades with a doctor blade


146


. A similar approach is shown in the leak controller


136




h


of FIG.


9


H. In this case, the processing solution


19


on the squeegee blade or blades


144




a


-


144




n


is cleaned off on a wheel


148


and the wheel cleaned by another squeegee


146


.




An alternative to applying processing solution


19


to the entire surface of the film


17


is to apply processing solution


19


only to the image area of the film


17


and also only to the area of the film


17


containing coded data, thereby ensuring that no processing solution is applied to clog the sprocket holes. An implementation of a slot coater for this purpose is shown in FIG.


10


. Shown are film


17


and a slot coater


24


. The film


17


includes an image area


149


, sprocket holes


150




a


,


150




b


, and a coded information area


152


. The slot coater


24


may be embodied as a slot coater similar but smaller in form and/or footprint than the slot coater described in FIG.


3


and

FIG. 4

above. Alternatively, the slot coater


24


may be implemented as a disposable “pen” having a porous tip


154


that is maintained in contact with the surface of the film


17


. Alternatively, an “ink jet”-type head may be employed to apply the developer to the coded information area


152


.




Once the processing solution


19


has been applied, a film processing system similar to that denoted by reference numeral


16


above may be used to read the coded information. The processor


18


may then use this information during development of the image area


149


, as generally described above.
