CROSS-REFERENCE TO RELATED APPLICATIONS

5 This application claims the benefit of co-pending United States provisional

application Serial No. 60/040,662 entitled "Spool Caddy For Use With Dry Optical

Image Processing of Roll Film" filed on March 11, 1997.

BACKGROUND OF THE INVENTION

1. Field ofthe Invention

10 This invention is directed generally towards an apparatus and method for use in

dry processing any photographic roll film, and more particularly towards a spool caddy

for use with a system, such as the system disclosed in Polaroid Case No. 8221, entitled

"System for Optical Dry Processing of Spooled Photographic Film", having United

States provisional application serial No. 60/040,388 filed on March 11, 1997 and also

15 filed as an utility patent application even date herewith, for pad processing of

photographic roll film, such as 35 mm film.

2. Description ofthe Prior Art

Pad processing is a well known dry optical image processing technique for

processing a photographic film using webs, also known as pads, which contain

20 processing fluids. Pad processing is considered a dry processing technique since liquid chemical baths are replaced with reagent laden webs which have been

imbibed with processing chemicals. Sometimes a pad is saturated with processing

chemicals and at other times, the processing chemicals are stored in a rupturable

pod. When the pod is ruptured, the processing chemicals are spread across the

web as a first step towards film development.

In U. S. Patent No. 5,440,366 issued August 8, 1995 to Reiss and Cocco, a

system and method are disclosed whereby individual processing pads are sequentially

wrapped onto a single processing spool. One embodiment discloses a processing

spool which houses all the processing webs such as: a first reagent laden web which

could be imbibed, for instance, with developing chemicals; a second reagent laden web

which could be imbibed, for instance, with bleaching and fixing chemicals; and a third

reagent laden web which could be imbibed, for instance, with washing and stabilizing

chemicals. A photographic film is housed in a separate standard 35mm cartridge. The

first web is combined with the film for a first preset time, then the first web and the

film are separated and the second web and the film are combined for a second preset

time, then the second web and the film are separated and the third web and the film are

combined for a third preset time. After the third web and the film are separated, the

optical processing of the photographic film is complete. An alternative embodiment

uses a standard size 35 mm cartridge for housing both the processing webs and the

photographic film. However, the standard size 35 mm cartridge limits the number of

exposures available from such a combined web/film spool. If the cartridge was made larger to hold more exposures, then it would not fit into a standard 35mm camera.

Also, the complete separation or isolation of each processing web from one another

and from the film is quite difficult.

The above and other disadvantages of existing processing systems are

overcome through the use of a spool caddy built in accordance with the principles of

the invention for use with a dry optical image processing system. The spool caddy

isolates processing spools from one another, and supports both the film cartridge and a

multitude of processing spools during processing.

SUMMARY OF THE INVENTION

A spool caddy for use with an optical dry image processor for processing a

photographic roll film housed in a film cartridge includes: a plurality of processing

spools, each containing a reagent laden pad for providing a processing step when

combined with an emulsion side ofthe film for a predetermined dwell time; and a

structure for detachably securing and supporting each processing spool in isolation

from one another. The structure can also accommodate the film cartridge. One end

of each processing spool and the film is attached to the structure.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Figure 1 is a perspective exploded view of a first embodiment of a spool caddy

1 which conforms to the principles of the present invention. The three major

components of the spool caddy 1 are the body 10, the snap plate 40 and the binding

lever 60. Each ofthe major components is preferably molded or otherwise made from

a strong, inexpensive, lightweight material such as polystyrene or any other plastic.

These components when assembled together form the spool caddy 1, shown with a

single processing spool 80 in Figure 2.

The body 10 acts as means, as shown in Figure 3C, for detachably securing and

supporting a number of processing spools 80, 90, 100, 110, as well as the film

cartridge 70, in isolation from one another. The body 10 includes a base 12, a plurality

of arms 14 and a wedge shaped cavity 20 positioned along the central longitudinal axis

16 ofthe spool caddy 1. The cavity 20 is indexed, notched or keyed in a lower section

ofthe body by a rectangular notch 22. Moreover, a slot 24 for engaging a film leader shown. The body 10 is keyed by a notch 18 as shown in Figure 2 which acts as a

means for enabling positional alignment of the spool caddy 1 in relation to other

components of a pad processing system (not shown). Other known means for

positional alignment of the spool caddy 1 can be used if desired. For instance, the

spool caddy 200 of Figures 8 and 9 can be aligned with any external structure (not

shown) via a keyed binding lever 204 as shown in Figure 11. The binding lever 204

includes a knurled top section 222, a retaining ring 224, an annular rib 226 and a lower

section 228. The lower section 228 in this case is oval shaped for a snug fit into the

lower section 230 (see Figure 10) of the cavity 212. The section 228 is designed to

extend beyond the plane of the base 210 for cooperation with an appropriately shaped

receptacle in an external structure, so that the spool caddy 200 will be keyed, i.e.

positionally aligned, to the external structure.

Turning back to the spool caddy 1 of Figures 1 and 2, the snap plate 40, having

a thickness "z", includes a centrally located cavity shaped opening 46 similar in shape

to the cavity 20 ofthe body 10, as well as a slot 25 corresponding to the slot 24 ofthe

body 10. The snap plate 40 functions as means for detachably retaining or holding

both a plurality of processing spools, such as the processing spool 80 of Figure 2, and

the film cartridge 70 of Figure 6A. The snap plate 40 may be clover shaped as shown

in Figures 1 and 2, or its shape could vary as shown by the snap plate 140 of Figure 4,

as long as it has the ability to detachably retain processing spools and film cartridges.

The snap plates 40 and 140 are both capable of detachably holding five spools, although the snap plates could be designed in cooperation with the spool caddy 1 to

retain more or less spools if desired. The snap plate 40 of Figure 2 includes five

identical leaf shaped sections 50 defining five identical spaces therebetween, each

space having a cross-sectional distance "a" and a narrow region of distance "m" at the

perimeter ofthe snap plate 40. Similarly, the snap plate 140 of Figure 4 includes five

claw shaped arms 45 each having a pair of claws 49 and 51 which also define five

identical spaces therebetween each having a cross-sectional distance "a" and a narrow

distance "m" located near the ends of the claws. The snap plate 40 or 140 and the

body 10 can be glued together, snapped together, screwed together, or otherwise held

together by any known fastening means. The embodiment of Figure 1 provides

clearance holes 42 in the snap plate 40 and raised bosses 44 on the body 10 which

allows the two parts to be joined together by ultrasonic staking to form the body/snap

plate assembly. The snap plate 140 of Figure 4 includes clearance holes 43 which

would be aligned with appropriately positioned raised bosses (not shown) replacing the

bosses 44 on the body 10.

The snap plate 140 also includes centrally located cutouts 130, 132 and 134 as

illustrated in Figures 4 and 5B. The cutout 130 is an hour glass shaped opening

defined by distances y„ y₂ and y₃, where y, = y₃ = y₄ , y₄ < y, and y₄ > y₂ (see also

Figure 5A). Cutout 134 is separated from the cutout 130 by a section 133, and cutout

132 is separated from the cutout 130 by a section 131. The binding lever 60 is designed as a means for detachably retaining, in

cooperation with the body 10, a film leader 76 ofthe film 71. First, the film leader 76

is inserted into the cavity 20 ofthe caddy body 10, then the binding lever 60 is inserted

through the top of the body/snap plate assembly so that the spring 62 is aligned with,

and snaps into, the notch 22. The diameter x₅ ofthe head 64 ofthe binding lever 60 is

large enough so that the head 64 can not pass into or through the cavity 20. Also, the

force of the spring 62 pushes the spring 62 against the internal wall of the notch 22 to

securely bind the lever 60 in the cavity 20. Hence, once the binding lever 60 is

inserted into the cavity 20 it cannot be removed. After insertion of the binding lever

60, the head 64 and the indent 66 of the binding lever 60 will both protrude above the

snap plate 40 as shown in Figure 2 to act in cooperation as a handle for inserting and

removing the spool caddy 1 from a pad processing system.

The binding lever 60 of Figure 1 includes: a shaft 68 of diameter x₆ and height

x,; an indent 66 of length x₃; a head 64 having a diameter x₅ and a thickness x₄; and a

spring 62 of length x₇ having a spring force which tends to extend the spring 62 away

from the shaft 68 as shown. When a force is applied to the spring 62 to bring it nearly

parallel with the longitudinal axis 16 ofthe shaft 68 (shown by dotted lines), the length

x₇ defines the distance from the bottom ofthe shaft 68 to the top end ofthe spring 62.

The length x₇ also corresponds to the length "k" ofthe notch 22 located adjacent to the

lower portion ofthe cavity 20 in the caddy body 10. The distance x, ofthe shaft 68 of

the binding lever 60 equates to the sum ofthe height "w" ofthe caddy body 10 and the width "z" ofthe snap plate 40 so that when the spool caddy 1 is completely assembled

as shown in Figure 2, the shaft head 64 and the indent 66 both protrude above the snap

plate 40.

Once the spool caddy 1 is assembled as shown in Figure 2, any movement of

the binding lever 60 in a direction crossing the central longitudinal axis 16 ofthe spool

caddy 1 is hampered by the force ofthe spring 62. Furthermore, any movement ofthe

binding lever 60 in a direction parallel to the longitudinal axis 16 is hampered by both

the head 64 and the physical engagement ofthe spring 62 within the notch 22.

When the user decides to process the film within a 35mm film cartridge 70

using a spool caddy 1 having a snap plate 40 and a binding lever 60, he first feeds the

film leader 76 into the slot 24 of the caddy body 10 and along the flat surface 125 of

the cavity 20 (see Figures 2, 3B and 3C). Next, the binding lever 60 is inserted as

described above so that the spring 62 snaps into the notch 22 and the film leader 76

becomes bound between the shaft 68 and the flat surface 125 in the cavity 20. The

film cartridge 70 is then detachably secured onto the spool caddy 1 by snapping the

core 72 of the film cartridge 70 into the clover leaf shaped snap plate 40. In order to

release the film leader 76, the user laterally applies pressure to the head 64 of the

binding lever 60 so that the shaft 68 moves slightly away from the flat surface 125.

A second type of binding lever 120 for use with the snap plate 140 of Figure 4

is shown in side view in Figure 5 A. The binding lever 120 includes a shaft 128 having

a cutout section 126. The shaft 128 has a diameter y₄, and further includes an annular rib 122 having a diameter greater than y₄. The binding lever 120 is designed to operate

in cooperation with the cutout section 130 of the snap plate 140 (see Figures 4 and

5B). The binding lever 120 is placed in an initial unlocked position as shown in Figure

5C by inserting lever 120 through y₃ of the cutout 130 and into the body/snap plate

assembly from the top until the spring 62 snaps into place within the notch 22.

The binding lever 204 of Figure 11 for use with the spool caddy 200 of Figure

8 has an annular rib 226 which functions in the same manner as the annular rib 122 of

the binding lever 120 shown in Figures 5 A, 5B and 5C. The top section 222 is knurled

for ease in gripping by the user. The lower section 228 extends beyond the plane of

the base 210 of the spool caddy 200 for cooperation with an appropriately shaped

receptacle in an external structure (not shown) for positional alignment of the spool

caddy 200. The retaining ring 224 functionally replaces the spring 62 (see Figure 5A)

by securing the binding lever 204 in the slot 212. Specifically, the spool caddy 200 is

assembled (without the spools installed) as shown in Figures 8 and 9 by inserting the

binding lever 204 into the cavity 212 of the body 202, then overlaying the snap ring

206 and attaching (e.g. by gluing, snap-fitting, heat sealing, etc.) the snap ring 206

onto the body 202. The retaining ring 224 thereafter prevents removal of the binding

lever 204 from the body 202.

When the user decides to process a 35mm film cartridge 70 using the spool

caddy 1 of Figure 1 having a snap plate 140, first, he feeds the film leader 76 into the

slot 24 of the caddy body 10 and into engagement with the flat surface 125 in the cavity 20. Then, he inserts the binding lever 120 into the unlocked position of Figure

5C so that the film leader 76 is loosely positioned in the cavity 20 between the flat

surface 125 and the shaft 128. The user then applies a lateral force to the head 124 of

the binding lever 120 so that the binding lever 120 is shifted and snapped into the

locked position shown in Figure 5D, whereby the film leader 76 is securely fastened in

the cavity 20 between the flat surface 125 and the shaft 128. When pushing the

binding lever 120 into the locked position, the binding lever 120 passes from y₃ (see

Figure 5B) through the region y, of the cutout 130 and into the locked position of

Figure 5D corresponding to the region y, of the cutout 130. When the binding lever

120 passes through the region y₂ of the cutout 130, the sections 131 and 133 will

slightly bend away from the cutout 130 and into the respective cutouts 132 and 134,

thus momentarily expanding the distance y₂ to allow passage ofthe binding lever shaft

128. After passage of the binding lever 60, the sections 131 and 133 resiliently return

to their original positions. The resultant locked position of the binding lever 120 is

illustrated in Figure 5D whereby the annular rib 122 is bound upon the inner surface

125 of the cavity 20 with the film leader 76 secured therebetween (not shown). Once

the film leader 76 is secured within the cavity 20, the film cartridge 70 can be

detachably secured onto the spool caddy 1 by snapping the core 72 of the film

cartridge 70 between two claws 49 and 51 ofthe snap plate 140.

The film leader 76 can be readily removed from the binding lever 120 by

moving the binding lever 120 into its unlocked or release position. This is accomplished by pushing the head 124 ofthe binding lever 120 from y, through y₂ and

into y₃, as viewed in Figure 5B, whereby the film leader 76 is then loosely positioned

between the annular rib 122 of the shaft 128 and the flat surface 125 to facilitate

removal therefrom.

The processing spools 80, 90, 100 and 110 of the current embodiment are each

factory installed into the spool caddy 1 in the same manner in which processing spool

80 is shown to be installed in Figure 2. Each processing spool as well as a standard 35

mm film cartridge 70 contains a hollow core 72 with dual drive tangs 74 recessed

therein (see Figures 6A, 6B, 6C, 7A, 7B and 7C) for transferring rotational drive force

from a source (not shown) to the core 72. The structure and dimensions of each

processing spool 80, 90, 100 and 110 is similar to that shown in Figures 7 A, 7B and

7C. Each processing spool and film cartridge contains a core 72 of diameter h, which

protrudes from one end ofthe body ofthe spool or cartridge by a height h₂.

The spool caddy 1 is designed to accommodate any 35 mm film cartridge or

processing spool by snapping the core 72 through the appropriate narrow region "m"

ofthe snap plates 40 or 140 and into the space having a cross-sectional distance "a" as

shown in Figures 1 and 4, whereby a = h, and m < a. Since the length and thickness of

the webs within the processing spools may likely be greater than the length and

thickness of the image carrying medium 71 within the film cartridge 70, then the

diameter h₄ of the processing spools may likely be greater than the diameter h₃ of a

standard size 35 mm film cartridge. Thus, the spool caddy 1 is built to accommodate spools having various diameters. Moreover, the snap plates 40 and 140 are made of a

flexible, resilient plastic which allows resilient spreading of the leaf sections 50 in the

snap plate 40 and the claws 49 and 51 in the snap plate 140 during insertion or removal

of the core 72. Once a processing spool is snapped into place in the spool caddy 1 as

shown in Figure 2, it is held there until a force is applied to remove the core 72

through the gap "m". The force required for inserting or removing the core 72 from

either snap plate 40 or 140 is adjustable by changing the material from which the snap

plate 40 or 140 is made, changing the thickness "z" of the snap plate 40 or 140, or by

adjusting the length and width of a channel 47 for each arm 45 ofthe snap plate 140.

Each processing spool contains a web having a protruding leader which is

fixedly attached to one arm 14 of the caddy body 10 as shown in Figure 3C. For

example, the web 82 of spool 80 has a protruding leader 86 which is fixedly attached

to one arm 14 at point 84. Alternatively, the web 82 can be secured to the body 10 as

shown in Figure 3D via a nub 81 located at the end of the web 82 which is inserted

into a slot 83 during installation of the processing spool 80 into the spool caddy 1.

Figure 3E illustrates a web 82 connected to arm 14 via a rivet 15 which allows

pivoting of the web 82 about the rivet 15 during unwinding and rewinding of the web

82 onto the spool 80. Any other known means can be used for fastening the web 82 to

the body ofthe spool caddy.

In the embodiment of Figure 3C, spool 80 is a developer spool which contains

a reagent laden web 82 imbibed with developing chemicals; spool 90 is a blix (i.e. bleaching and fixing) spool which contains a reagent laden web 92 imbibed with a

combination of bleaching and fixing chemicals; spool 100 is a wash spool which

contains a web 102 soaked with a combination of washing and stabilizing agents; and

spool 110 is a blotter spool which contains a web 112 of dry non-woven material.

The assembled spool caddy 1 contains the body 10, the snap plate 40, the

binding lever 60, and the preselected processing spools. The number and contents of

the processing spools of a particular spool caddy can vary according to the needs for

processing a particular roll film. For instance, if separate bleaching and fixing steps

are desired, then the blix spool 90 could be replaced by two separate spools, one

containing a reagent laden web imbibed with bleaching chemicals, and the other

containing a reagent laden web imbibed with fixing chemicals. The spool caddy 1

would then require six arms 14 and the snap plate 40 would require six leaf shaped

sections 50.

Of course, processing spools with other processing capabilities could be added

to the spool caddy 1 if desired. The number of arms 14 on the caddy body 10 and the

number of leaf shaped sections 50 on the snap plate 40, or claws 45 on the snap plate

140, can change in accordance with the number of spools desired or required for film

processing. Moreover, the arms 14 can take any desired shape as long as they provide

both support for the various spools, and isolation of those spools from one another.

Also, any snap plate design may be used that allows the snap plate to detachably hold

each spool in place. Furthermore, the processing spools could be encased in hard shell cartridges, similar to 35m cartridges, so that a snap plate could detachably retain the

bodies ofthe hard shell processing cartridges, rather than the cores as described above.

A modified version ofthe above-described spool caddy 1 would house only the

processing spools, i.e. the modified spool caddy 1 would not house the film cartridge

70. In this embodiment, the structural components ofthe spool caddy 1 which interact

solely with the film 71 or the film cartridge 70 become unnecessary. In other words,

the binding lever 60, the slot 24 and the cavity 20 would no longer be needed.

Figure 8 is a perspective exploded view of a second embodiment of a spool

caddy 200 which conforms to the principles of the present invention. The three major

components of the spool caddy 200 are the body 202, the snap ring 206 and the

binding lever 204. Each of the major components is preferably molded or otherwise

made from a strong, inexpensive, lightweight material such as polystyrene or any other

plastic. These components when assembled together form the spool caddy 200, shown

assembled (without processing spools) in Figure 9.

The operability of the three components 202, 204 and 206 is similar to that of

the previously described parts 10, 60 and 40, respectively shown in the spool caddy 1

of Figure 1. The body 200 is similar to the body 10 by functioning to detachably

secure and support a group of processing spools, plus a film cartridge, in isolation from

one another. The body 200 includes a base 210, a plurality of arms 208 and a cavity

212 positioned along the central longitudinal axis 218 of the spool caddy 200. The

body 200 also includes a spacer section 219, located between two arms 208, which can be enlarged, diminished or eliminated as necessary to provide proper spacing and

orientation ofthe desired number of processing spools to be mounted on the body 200.

The body 202 ofthe spool caddy 200 is a single molded piece which includes a

plurality of claw-shaped arms 45 each having a pair of claws 49 and 51. A processing

spool or film cartridge is installed onto the spool caddy 200 by snapping the core 72 of

the selected spool between the claws 49 and 51 in the same manner as shown for the

embodiment of Figure 2. Alternatively, each selected spool can be mounted or

removed from the body 202 via cutouts 214 which allow the bottom portion (opposite

core 72) ofthe selected spool to be engaged by a mechanism (not shown) for removing

or returning the selected spool from or to the spool caddy 200, respectively.

The inventive spool caddy as claimed and described herein in various

embodiments can be used for pad processing any photographic roll film with a variety

of image processing systems such as, but not limited to, the processing systems

disclosed in Polaroid Case No. 8221 filed on even date herewith. The functionality of

the spool caddy in cooperation with other elements of a pad processing system are

described in detail in the above related patent application.

It is to be understood that the above described embodiments are merely

illustrative of the present invention and represent a limited number of the possible

specific embodiments that can provide applications of the principles of the invention.

Numerous and varied other arrangements may be readily devised in accordance with these principles by those skilled in the art without departing from the spirit and scope

ofthe invention as claimed.
