DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and an apparatus for conveying a photosensitive material in which a long photosensitive material such as a photographic film is co-wound with a processing film for forming a photosensitive material and is processed with a processing solution.

2. Description of the Related Art In recent processing of color photographic light-sensitive materials,
The leading role is shifting from centralized processing in large-scale laboratories to in-store processing called a minilab, and the processing mode is shifting to distributed small-volume processing. In addition, a minilab-scale processing equipment can be installed not only in photo shops but also in various stores, and can also be installed in stores of other industries, such as bookstores, gas stations, cleaning shops, supermarkets, and convenience stores. I will be able to be. Of course, such a development processing device placed in a store should preferably have a small installation area, and the configuration of the device must be simple in consideration of the operation, maintenance, and failure of the device.

Conventionally, a 135-size negative film generally used is detached from the spool shaft of the patrone (or cut near the spool shaft) and transported through a plurality of processing tanks by transport rollers or the like. A development process is performed.

Further, a developed negative film has been cut at a predetermined number of frames and returned to customers as a piece negative.

In recent years, there has been a new system called APS (Advanced Photo System) for returning a developed negative film in a cartridge without cutting the negative film.

In this new system, a negative film is taken out of a cartridge received from a customer and developed, and the developed negative film is stored in the original cartridge and returned to the customer.

For this reason, a device called a detacher for separating the negative film from the spool shaft of the cartridge and a device called an attacher for locking the developed negative film to the spool shaft of the cartridge are required.
When the process of separating the negative film from the spool shaft of the cartridge, the process of developing the separated negative film, and the process of locking the developed negative film to the spool shaft of the cartridge are performed by one device, It becomes complicated and causes an increase in the size of the device.

On the other hand, as described in, for example, JP-A-4-230745, there is a method in which a film is developed with a processing solution in a container while being wound around a dummy film having a convex portion. This method simplifies the structure of the container and is suitable for a small throughput.

[0009]

However, in the above method, the developing process of the photosensitive material cannot be performed properly unless the dummy film and the photosensitive material are co-wound securely.

In view of the above facts, an object of the present invention is to provide a method and an apparatus for conveying a photosensitive material suitable for a small processing amount and capable of reliably winding a photosensitive material and an interval forming film for processing a photosensitive material. .

[0011]

According to the first aspect of the present invention, a long photosensitive material accommodated in a photosensitive material container and a long photosensitive material processing interval forming film are accommodated in a processing tank. A method of transporting a photosensitive material, wherein the photosensitive material is co-wound to develop the photosensitive material, wherein a plurality of first protrusions are provided along the longitudinal direction near both ends in a width direction and formed to be lower than the first protrusions. A plurality of second projections are provided along the longitudinal direction inward of the first projection in the width direction, and the difference in height between the first projection and the first projection is larger than the thickness of the photosensitive material. The photosensitive material is removed from the photosensitive material storage container in a state where one end of the photosensitive material processing interval forming film having the one end is locked to a rotating shaft in the processing tank and one end is locked to a spool shaft of the photosensitive material storage container. The interval forming film for processing the photosensitive material. Out of the photosensitive material processing interval forming film and the photosensitive material container by rotating the rotating shaft. The film is co-wound with the rotating shaft.

Next, the operation of the photosensitive material conveying method according to the first aspect will be described. In the method for transporting a photosensitive material according to claim 1, the photosensitive material is disposed from the photosensitive material container to the vicinity of both ends in the width direction of the photosensitive material processing interval forming film with one end locked to a spool shaft of the photosensitive material container. Is fed so as to be inserted between the first projections, and the rotating shaft is rotated so that the photosensitive material processing interval forming film and the film sent from the photosensitive material container are co-wound around the rotating shaft in the processing tank. Is done. Thereafter, the photosensitive material in the processing tank can be developed by supplying the developing processing to the processing tank.

Here, one end of the photosensitive material processing interval forming film is locked to the rotating shaft in the processing tank.
By rotating the rotation shaft, the photosensitive material and the photosensitive material processing interval forming film can be reliably co-wound in the processing tank.

The first projection forms a gap through which the processing liquid passes between the overlapping photosensitive material processing space forming films. Further, the second projection which is in contact with the photosensitive material when co-wound is lower than the first projection, and the difference between the heights of the first projection and the second projection is larger than the thickness of the photosensitive material. Since it is large, a gap through which the processing liquid passes can be formed on both sides of the photosensitive material.

According to a second aspect of the present invention, in the method for transporting a photosensitive material according to the first aspect, when the photosensitive material and the photosensitive material processing interval forming film are co-wound around the rotating shaft, It is characterized by applying tension to the photosensitive material.

Next, the operation of the photosensitive material conveying method according to the second aspect will be described. In the method of conveying a photosensitive material according to the second aspect, the photosensitive material is co-wound with the photosensitive material processing interval forming film around the rotating shaft while applying tension to the photosensitive material. Accordingly, the photosensitive material is co-wound without loosening between the photosensitive material processing interval forming films.

According to a third aspect of the present invention, there is provided an elongated photosensitive material having a plurality of projections forming an interval between the elongated photosensitive material fed from the photosensitive material container and the photosensitive material. A method for transporting a photosensitive material in which a processing interval forming film is co-wound in a processing tank to develop the photosensitive material, wherein the photosensitive material and the photosensitive material processing interval forming film are co-wound. The photosensitive material is fed out of the photosensitive material container so that the surface of the photosensitive material opposite to the photosensitive surface faces the protrusion.

Next, the operation of the method for transporting a photosensitive material according to the third aspect will be described. In the method for transporting a photosensitive material according to the third aspect, the photosensitive material is fed out of the photosensitive material container so that the surface opposite to the photosensitive surface of the photosensitive material faces the projection. Therefore, when the photosensitive material and the photosensitive material processing interval forming film are co-wound around the rotating shaft, the surface opposite to the photosensitive surface of the photosensitive material faces the projection. Therefore, the projection does not contact the photosensitive surface of the photosensitive material.

According to a fourth aspect of the present invention, the long photosensitive material accommodated in the photosensitive material container and the long photosensitive material processing interval forming film are co-wound in a processing tank. An apparatus for transporting a photosensitive material for developing a photosensitive material, wherein an insertion opening for inserting the photosensitive material and the photosensitive material processing interval forming film formed in the processing tank,

And a second protrusion having a height difference from the first protrusion that is larger than the thickness of the photosensitive material, and the first protrusion and the second protrusion are not formed. A photosensitive material processing interval forming film having a non-projection region on one end side, and an interval forming film transporting means provided outside the processing tank and transporting the photosensitive material processing interval forming film in a direction of coming into contact with and separating from the insertion port; A rotating shaft provided in the processing tank, the other end of the photosensitive material processing gap forming film being locked, and winding the photosensitive material processing gap forming film, a driving unit for rotating the rotating shaft, Photosensitive material Detecting means for detecting the length, photosensitive material transporting means for transporting the photosensitive material in the direction of coming into contact with and separating from the insertion opening, closing means for closing the insertion opening, The interval forming film according to the length of the photosensitive material detected by the detection means, so that the projection-free region of the photosensitive material processing interval forming film corresponds to the insertion port at the time when the film is fed into the tank. Control means for controlling a conveying means, a driving means and a photosensitive material conveying means to convey the photosensitive material and the photosensitive material processing interval forming film.

The operation of the photosensitive material conveying device according to the fourth aspect will be described. The length of the photosensitive material is detected by the detecting means. The length is
It may be detected indirectly from the number of photographed photosensitive materials, or the actual length of the photosensitive material may be directly measured.

By rotating the rotating shaft by the driving means, the photosensitive material processing interval forming film can be wound around the rotating shaft of the processing tank. At this time, the interval forming film for processing the photosensitive material may be conveyed to the insertion port by the interval forming film conveying means. On the other hand, the rotating shaft is rotated in the direction opposite to the winding direction, and the interval forming film for photosensitive material processing can be transported out of the processing tank by driving the interval forming film transport means in the direction opposite to the winding direction. .

When the photosensitive material processing interval forming film is wound around a rotating shaft, the photosensitive material conveying means is driven to direct the photosensitive material toward the insertion opening of the processing tank, and the first of the photosensitive material processing interval forming films. If the photosensitive material and the photosensitive material processing space forming film are fed out so as to be inserted between the protrusions, the photosensitive material and the photosensitive material processing space forming film can be co-wound around the rotating shaft.

Here, the control means detects the photosensitive material to be developed by the detecting means so that the projection-free region of the photosensitive material processing interval forming film corresponds to the insertion port when the photosensitive material to be developed is fed into the processing tank. The distance forming film transporting means, the driving means, and the photosensitive material transporting means are controlled in accordance with the length of the photosensitive material, and the photosensitive material and the photosensitive material processing distance forming film are transported. More specifically, the length of the photosensitive material processing interval forming film is adjusted to the length of the longest photosensitive material to be developed.

When processing a photosensitive material having a short length,
The interval forming film for processing the photosensitive material is idlely fed by the difference between the longest photosensitive material and the shortest photosensitive material and wound on a rotating shaft, and thereafter, the transport of the photosensitive material is started. Thereby, when the photosensitive material to be developed is inserted into the processing tank, the non-projection area of the photosensitive material processing interval forming film can correspond to the insertion opening.

When the photosensitive material to be developed is fed into the processing tank, the projection-free region of the photosensitive material processing interval forming film corresponds to the insertion opening. In this state, the insertion opening is closed by the closing means. Since the photosensitive material and the non-projection region of the photosensitive material processing interval forming film are in close contact with each other, the inside of the treatment tank can be sealed.

When the photosensitive material and the photosensitive material processing space forming film are co-wound around the rotating shaft, the first projections are formed between the overlapping photosensitive material processing space forming film and the photosensitive material processing space forming film. Then, a gap through which the processing liquid passes is formed. Further, the second projection which is in contact with the photosensitive material when co-wound is lower than the first projection, and the difference between the heights of the first projection and the second projection is larger than the thickness of the photosensitive material. Since it is large, a gap through which the processing liquid passes can be formed on both sides of the photosensitive material.

In this state, by supplying the developing solution into the processing tank, the photosensitive material in the processing tank can be developed. Since the inside of the processing tank is sealed by the closing means, the processing liquid does not leak outside.

As shown in FIGS. 8 and 9, the other end of the embossed film 612 serving as the photosensitive material processing interval forming film is engaged with a winding drum 624 rotated by a motor 622.

In the processing tank 600, the film F as a photosensitive material is an embossed film 61 made of a synthetic resin or the like having a shape as shown in FIGS.
It is accommodated in the tank with the wrapper around 2.

On both sides in the width direction of the embossed film 612, high protrusions 614 as first protrusions are formed at predetermined intervals along the longitudinal direction, and inside thereof, low protrusions 616 as second protrusions are formed. It is formed along the longitudinal direction. As shown in FIG. 10A, a portion where the high protrusion 614 and the low protrusion 616 are not formed is provided on the side (left side in FIG. 10A) which is locked to the winding drum 624. The portion is located at the film insertion port 606 when the inside of the tank is sealed with the packing 610.

The total length L of the embossed film 612,

As shown in FIGS. 7 and 8, a portion on which a high protrusion 614 and a low protrusion 616 are formed is wound around the winding shaft 618 in advance for one turn and fixed.

In the present embodiment, the film F fed from the cartridge 14 is disposed between the high protrusions 614 as shown in FIG. It is wound on a take-up shaft 618 together with the embossed film 612.

Film F together with embossed film 612
When the film is wound on the winding shaft 618, the low protrusion 616 contacts the opposite side of the emulsion side of the film F, and a gap through which the processing liquid flows is formed on both sides of the film F as shown in FIG. You.

Here, the embossed film 612 can be formed of various materials as long as the high protrusion 614 and the low protrusion 616 are formed on the band-like base portion 612A as described above. For example, PET, PE
It can be formed of a film or fabric of synthetic resin such as N, PP, PE, polyester, etc., rubber such as EPT, butyl rubber, chloroprene rubber, silicon rubber, thermoplastic plastic such as TPE (elastomer), and metal such as stainless steel.

The embossed film 612 can also be formed by attaching pins (studs) made of stainless steel or the like to a band of a film or a fabric.

As shown in FIG. 11, the embossed film 6
12 has a thickness t of 0.05 to 2.0.
mm is preferable, and 0.2 to 1.0 mm is more preferable.
More preferably, it is 2 to 0.6 mm.

As described above, since the film F and the embossed film 612 are co-wound, the embossed film 61
2 needs to have almost the same flexibility as the film F. Further, the embossed film 612 must hold the film F, form a gap, and hold the film F. The embossed film 612 needs to have a gap holding property, flatness, and buckling resistance when co-wound. Good performance is essential. Taking these into consideration, 0.2 mm or more is practical for organic materials.

Next, when the thickness of the embossed film 612 is large, the size of the processing tank 600 to be wound becomes large, and the unbalance of the flow of the processing liquid due to the non-uniformity of the co-wound film F increases. The thickness equivalent to that of the film F is good in balance. In this sense, 1.0 mm or less is practical for organic materials.

The height H of the high protrusion 614 is preferably 0.3 to 3 mm, more preferably 0.5 to 1 mm.

The reason is as follows.
This is because, in order to maintain the gap between the two, it is necessary to provide a gap in which the film F is interposed and through which the processing liquid passes. In addition, a high protrusion 61 when co-wound
4 and the change due to deformation of the film F also need to be considered. For this reason, a height of 0.3 mm or more, which is higher than the film thickness, is required. Furthermore, if the gap is excessively vacant during co-winding, the flow rate and flow rate of the processing solution become inappropriate, which causes unevenness and bubble failure in the film F.

On the other hand, the height h of the low protrusion 616 is 0.1 to
It is preferably 1.5 mm, more preferably 0.2 to 0.5 mm.

The reason is as follows.
This is a value that secures a gap between the film 2 and the film F, and is sufficient if a minimum flow of the liquid is generated, and 0.2 mm or more is preferable in consideration of a change due to the low protrusion 616 and deformation of the film F. Also, the height need not be high. The gap due to this height is on the side opposite to the emulsion side of the film F and does not require much strictness, but the value of Hh is important.

However, when the film F is wound around the winding shaft 618 together with the embossed film 612, at least the emulsion side of the film F is 0.1 to 1.0 mm, preferably 0.2 to 0.5 mm Is preferably formed.

When the gap is less than 0.1 mm, the passage of the processing solution on the emulsion surface side is likely to be non-uniform. In particular, the size of the gap may be different between the vicinity of the low protrusion 616 and the place off the low protrusion 616. As a result, development unevenness and poor development are likely to occur.

The high protrusion 614 and the low protrusion 616
Is preferably formed in an arc shape (for example, hemispherical shape) so as not to damage the contacting partner.

The pitch P ₁ of the high protrusion 614 is 2
It is preferably from 10 to 10 mm, more preferably from 3 to 5 mm.

If the pitch P ₁ is too long, when the film F is wound around the winding shaft 618 together with the embossed film 612, the film F does not form a clean spiral, but becomes a polygonal wound state, or the emulsion surface of the film F The gap formed on the side may be too small in some cases, or the film F may contact the embossed film 612 in some cases.

On the other hand, the pitch P ₂ of the low protrusion 616 is 2
It is preferably from 10 to 10 mm, more preferably from 3 to 5 mm.

If the pitch P ₂ is too long, when the film F is wound on the winding shaft 618 together with the embossed film 612, the film F may not be formed in a clean spiral shape but in a polygonal wound state. In such a case, the gap formed on the emulsion surface side of the film F is partially changed, and in some cases, the film F may come into contact with the embossed film 612, and development unevenness or poor development is likely to occur. .

[0092] Further, as shown in FIG. 11, when viewed embossed film 612 in the width direction, the diameter L ₁ the thickness of the high protrusion 614, 0.5 to 2.0 mm are preferred, 0.
More preferably, it is 5 to 1.0 mm.

If the diameter L ₁ is larger than 2.0 mm, flow resistance and unevenness are generated when the processing liquid passes, which tends to cause uneven development and poor development. Further, the cross section perpendicular to the axis is preferably an elliptical shape or an airfoil shape that does not cause resistance when the processing liquid passes, and a shape that generates a uniform flow on the film surface is preferable.

Further, as shown in FIG. 11, it is preferable that the inside of at least the high protrusion 614 is blocked. For example, when the film F is wound around the winding shaft 618 together with the embossed film 612, the high protrusion 61 is necessarily provided somewhere.
The place where 4 overlaps comes out. At this time, if the inside of the high protrusion 614 of the embossed film 612 is concave, FIG.
When the embossed films 612 overlap as shown in FIG. 2, the high protrusions 614 on the winding shaft 618 side enter the recesses of the high protrusions 614 located thereon, and maintain the space between the embossed films 612 and 612. May occur.

Also, as shown in FIG.
The distance between the inside of the projection 4 and the high projection 614 is set to be slightly wider than the width of the film F, and the low projection 616 is set at a position that does not cover the image frame 64 (see FIG. 4).

Are protrusions 614 that are high in the width direction as shown in FIG.
And low projections 616 may be paired,
As shown in FIG. 10B, a high protrusion 614 and a low protrusion 616 in the width direction may be paired.

The heater 50 and the heater 852 are connected to and controlled by the controller 122. (Operation) Next, the operation of the present embodiment will be described.

In the initial state of the apparatus, as shown in FIG. 9, the station 104 is located at a position away from the processing tank 600, and the roller 818 of the arm 814 is located above the motor 802 for driving the lever 800.

When the cartridge 14 containing the undeveloped film F is loaded into the recess 116 of the station 104 and the start button is turned on, the rotation lever 118 is turned on.
Rotates to hold the cartridge 14. Thereafter, the barcode 80 of the cartridge 14 is read by the barcode scanner 121, and the control device 122 temporarily stores the number of shots of the film F (that is, the length of the film F) and the film type.

Next, the motor 802 operates to operate the lever 80.
0 rotates clockwise, and the station 104 holding the cartridge 14 is moved to the processing tank 6 as shown in FIG.
It is located near 00.

Next, the chucking device 130 operates,
The door driver 126 is connected to the key hole 34 of the door shaft 32.
Then, the spool driver 128 is engaged with the key hole 62 of the spool shaft 16.

After that, the door driver 126
2, the spool driver 128 is rotated by the motor 134, and the cueing of the film F is performed.

When the film F is sent out from the cartridge 14, the rollers 806, 808 and the winding shaft 61
8, the film F and the embossed film 612 are wound around the winding shaft 618 of the processing tank 600 as shown in FIG.

Here, the spool shaft 1 of the cartridge 14
In FIG. 6, a film F is wound up with the emulsion surface inside. Therefore, in the present embodiment, the surface opposite to the emulsion surface (photosensitive surface) of the film F comes into contact with the low protrusion 616 of the embossed film 612 and is wound around the winding shaft 618, so that the processing of the entire emulsion surface is ensured. And no adverse effect on the flexible emulsion surface.

Further, the winding speed of the film F by the winding shaft 618 is set slightly higher than the feeding speed of the film F by the motor 134. For this reason, the film F is wound around the winding shaft 618 together with the embossed film 612 without slackening under tension.
The contact between the emulsion surface of the film F and the embossed film 612 due to the loosening of the film F in the processing tank 600 can be reliably prevented.

The timing at which the conveyance of the embossed film 612 is started depends on all the image frames 64 of the film F.
Is inserted into the processing bath 600, the portion where the high protrusion 614 and the low protrusion 616 are not formed becomes the processing bath 60.
The operation is performed so as to face the film insertion port 606 of No. 0.

Therefore, the timing at which the conveyance of the embossed film 612 is started differs depending on the length of the film F (the number of shots). The cartridge 1
4 according to the number of shots of the film F read from the barcode 80 of No. 4 (that is, the length of the film F).
2 determines the timing at which the conveyance of the embossed film 612 is started.

Here, since the entire length of the embossed film 612 is set according to the longest film F to be processed, when the short film F is processed, the embossed film 612 is fed in advance and the winding shaft 618 is used. Then, feeding of the film F is started.

When all the image frames 64 of the film F are inserted into the processing tank 600, the cylinder 608 is operated as shown in FIG.
14 and the portion where the low protrusion 616 is not formed and the film F are pressed against the film insertion port 606 by the packing 610, and the film insertion port 606 is closed.

Next, the development processing of the film F with the processing liquid will be described. When the processing tank 600 is sealed, the color developing solution in the color developing tank 700 is sent to the processing tank 600 via the pump 706, the solenoid valve 708, the solenoid valve 710, and the connection 602. At this time, the air release solenoid valve 7
50 is opened and the air inside is pushed out, and the processing tank 60 is opened.

Thereafter, the pump 706 stops and the solenoid valve 7
10 is switched, the electromagnetic valve 750 is closed, and the color developing solution in the processing tank 600 circulates through the pump 724, the electromagnetic valve 726, and the electromagnetic valve 710 for a predetermined time.

Thereafter, the electromagnetic valve 710 is switched, and the pump 706 and the pump 724 are operated to return the color developing solution to the color developing solution tank 700. At this time, the solenoid valve 7
50 is opened, and the processing tank 600 is replaced with air.

Next, the bleach-fixing solution in the bleach-fixing solution tank 702 is sent to the processing tank 600 via the pump 712, the solenoid valve 714, the solenoid valve 708, the solenoid valve 710, and the connection portion 602. At this time, the air release solenoid valve 750 opens,
The internal air is pushed out, and the processing tank 600 is filled with the bleach-fix solution.

Thereafter, the pump 712 stops and the solenoid valve 7
10 is switched, the electromagnetic valve 750 is closed, and the bleach-fix solution in the processing tank 600 circulates through the pump 724, the electromagnetic valve 726, and the electromagnetic valve 710 for a predetermined time.

Thereafter, the electromagnetic valve 710 is switched, and the pump 712 and the pump 724 are operated to return the bleach-fix solution to the bleach-fix solution tank 702. At this time, the solenoid valve 7
50 is opened, and the processing tank 600 is replaced with air.

Thereafter, the stable liquid in the stable liquid tank 704 is supplied to the pump 716, the solenoid valve 718, the solenoid valve 714, and the solenoid valve 70.
8, the processing tank 60 via the solenoid valve 710 and the connection portion 602
Sent to 0. At this time, the air release solenoid valve 750
Is opened to push out the air inside, and the processing tank 600 is filled with the stabilizing liquid.

Thereafter, the pump 716 stops and the solenoid valve 7
10 is switched, the electromagnetic valve 750 is closed, and the stable liquid in the processing tank 600 circulates for a predetermined time via the pump 724, the electromagnetic valve 726, and the electromagnetic valve 710.

Thereafter, the solenoid valve 710 is switched, and the pump 716 and the pump 724 operate to return the stable liquid to the stable liquid tank 704. At this time, the electromagnetic valve 750 opens, and the processing tank 600 is replaced with air.

Note that, while processing the film F with one processing liquid, the pump 724 may be reversed to appropriately reverse the direction in which the processing liquid flows in the processing tank 600.

As described above, the film F is formed into a color developing solution,
When the processing is sequentially performed by the bleach-fixing solution and the stabilizing solution, the cylinder 608 is operated to separate the packing 610 from the film insertion port 606.

Before the processing of the film F with the processing liquid is completed, the controller 122 controls the fans 828, 832,
The heaters 830 and 834 are energized to set the inside of the duct 822 to θ ₁ ° C and the inside of the duct 824 to θ ₂ ° C (provided that θ ₁ <θ ₂ ).

When the packing 610 separates from the film insertion slot 606, the motor 802 operates and the lever 800 rotates in the counterclockwise direction to rotate the station 104.
Is disposed at a position away from the processing tank 600 as shown in FIG. 17, and the film F is wound around the roller 818 of the arm 814.

Thereafter, the linear moving mechanism 816 operates to move the arm 814 in the direction of the arrow L, and the processed film F is sequentially pulled out of the processing tank 600 while being wound around the rollers 818 of the arm 814. As shown at 18, it is fed into the drying box 820. At this time, the take-up shaft 618, the take-up drum 624, the rollers 806 and 808 rotate in unison with the film F to be pulled out, and are unraveled by a fixed amount.

[0151] The filter fed into the drying box 820
Lum F is heated by the warm air (θ _Two° C) and duct
822 warm air (θ₁° C)
The drying process for a given period of time is performed.

When the drying of the film F fed into the drying box 820 is completed after a certain period of time, the inside of the duct 822 becomes θ ₃ ° C, and the inside of the duct 824 becomes θ _4.
° C (however, θ ₃ > θ ₄ ), the spool driver 128 is rotated by the motor 134, the roller 806 is again rotated by the motor 804, and the winding drum 62
4 is rotated by a motor 622, and the film F is sequentially wound around the spool shaft 16 of the cartridge 14 at a constant speed.

[0153] undried portion of the pulled out from the processing tank 600 film F is dried is blown hot air (θ ₃ ° C) of the hot air (θ ₄ ° C) and the duct 822 of the duct 824 while being conveyed You.

As described above, also in the present embodiment, a difference is made in the drying ability between the side closer to the cartridge 14 and the side farther from the cartridge 14.
By setting the drying conditions during stoppage and the drying conditions during conveyance as described above, the film F can be dried in a short time with minimum energy.

In this embodiment, since the warm air is blown from both sides of the film F conveyed in a substantially U-shape, when the film F separates from the rollers 806 and 808, there is a possibility that the films F come into contact with each other. There is a film F
Since the shielding member 280 is interposed between the films, contact between the films is avoided, and drying can be performed stably.

When the cartridge 30 is completely wound around the spool shaft 16, the door 30 is closed and the door driver 12 is closed.
The spool driver 128 moves away from the cartridge 14.

After that, the rotating lever 118 rotates and retracts from the concave portion 116, and the cartridge 14 containing the developed film F can be taken out.

When the film F reaches a predetermined processing amount, the control device 122 drives the pumps 736, 738, and 740 to replenish the tank with a predetermined amount of replenisher. In addition, the deteriorated processing solution is switched by the electromagnetic valve 726 to discharge the waste liquid 4.
It can be discharged to 54. [Second Embodiment] A second embodiment of the present invention will be described with reference to FIG. The same components as those in the above-described embodiment are denoted by the same reference numerals, and description thereof will be omitted.

In this embodiment, the film F pulled out of the cartridge 14 is sent to the processing tank 600 while being sandwiched between a roller 948 rotated by a motor 946 and a driven roller 950 pressed against the roller 948.

The speed at which the film F is wound by the winding shaft 618 is set to be slightly higher than the speed at which the film F is conveyed by the motor 946. For this reason, the film F is wound around the winding shaft 618 together with the embossed film 612 without being loosened under tension, and the emulsion surface of the film F and the embossed film 612 due to the film F being loosened in the processing tank 600. Contact can be reliably prevented.

When the film F is pulled out by the roller 948 and the driven roller 950, it is not necessary to apply a voltage to the motor 134 of the spool driver 128 for rotating the spool shaft 16 to rotate the spool 134.

The method of applying tension to the film F when co-wound with the embossed film 612 is not limited to the method of the above embodiment.

If the winding tension of the film F is large, the film F is applied with too much force, so that the film F is wound in a polygonal shape, a mark is formed on the film F, or the film F slips. Problems such as unevenness and scratches occur.

On the other hand, if the winding tension of the film F is small, the film F becomes loose and undulates, so that the film F and the embossed film 612 cannot be wound neatly and become bamboo-like. In addition, adverse effects such as failure to maintain a predetermined interval occur.

That is, the tension of the film F is 10 g
5,000 g, preferably 50 g to 500 g.

The embossed film 612 has a tension of 50 g to 8000 g, preferably 100 g to 10 g.
It is good to be 00g.

As a method of applying tension to the film F, besides a control method in which the speed at the sending side is slightly slower than that at the winding side, for example, the tension may be applied to the film F even when a brake is applied to the motor or roller at the sending side. The tension can also be applied to the film F by pressing a tension roller or the like against the film F being conveyed. The method of applying tension to the film F is not limited to these methods.

As another method of giving tension to the film F, if a condition in which the film can be wound with a constant tension even when the winding diameter changes by utilizing the characteristics of the torque motor, a simple and relatively good result can be obtained. Obtainable.

In the present invention, not only APS films but also other types of films such as 135 films can be processed, and any type of film can be used as long as it is long.
