[Prior Art] In general, an automatic photosensitive material processing device develops and then dries photographic material that has already been photographed. In particular, sheet-like photographic materials such as color photographic paper, X-ray film for direct photography, etc. For Ray film, printing film, etc., processing percentage
It is desired that the 'H be smaller in size, stable in processing, easy to fabricate, and easy to clean and maintain. Automatic processing equipment that processes silver halide photosensitive materials such as photographic film and photographic paper usually has processing WIIs (the content, order, number, etc. of the photosensitive materials to be processed) such as development, fixing, and water washing installed in the housing. (varies depending on the material) and a drying chamber, in which the photosensitive material is sequentially conveyed through each processing tank by conveyance means such as conveyance rollers, developed with each processing solution, and then transported into a drying chamber and exposed to warm air. Once dried, it is also discharged as an adult. Figure 11 shows a copying machine equipped with such an automatic processing device.
An example of a is a copying latent image forming device consisting of an image exposure unit 81S10 on the top stage, a paper feed 111s20 on the right side, and a photosensitive material conveying unit 30, and a developing unit 1' below the image exposure unit 10! 1RK40 and its left side dry fils5
The image exposure section 10 includes a document platen, a light source 12, a light source 12, a first
Mirror 13.1132 Consists of a mirror 14, a third mirror 15, a lens 16, and a shutter 17. Above light N212
And mirror 1: Exposure scanning by Li2, 1s is known electrophotography 8! However, by using an odd number of mirrors, the image is inverted, and a latent image corresponding to the original image is directly formed on the photosensitive surface of the photosensitive material. Here, the shutter 17 opens in synchronization with the above-mentioned exposure scanning and closes late at other times to prevent external light fog from occurring on the photosensitive material. The photosensitive material used here is silver halide 4, on which a positive image is formed by exposure and development.
It is a material with a high level of sensitivity. The photographic material is formed into a roll, and the magazine 21
It is stored in a light and sound state inside. The leading end of the roll-shaped silver halide photographic light-sensitive material (hereinafter referred to as roll-shaped light-sensitive material) R in the magazine 21 is fed into the conveying section 30 . The roll-shaped photosensitive material R inserted into the conveying section 30 is held by a group of conveying rollers that are in pressure contact with each other and is sent upward to a predetermined length (for example, A4 size short side, B41!11 short side, A3t-1
When the sheet is fed, it is cut by a cutting device into a cut sheet. This cut sheet-shaped silver halide photographic light-sensitive material (hereinafter referred to as sheet-shaped light-sensitive material) S is fed along a transport path shown by a dashed line in the figure. During this feeding process, while the sheet-like photosensitive material S is being fed and passing through the image forming position (focusing glass) 18 of the image exposure section 10, the exposure scanning member is moved onto the document table lath 11 in response to this. The original image is exposed and scanned with a predetermined width, and the resulting scanning exposure light flux passes through the lens 16 and the shutter 17 to the imaging position 18.
A latent image is formed on the sheet-like photosensitive material S. Furthermore, a sheet-like photosensitive material S1 on which a latent image has been formed. is sent to the development processing section 40 by a conveyance roller. The development processing section 40 includes (1) a first developer tank 41, a second developer tank 42, a bleach-fix tank 43, a first stabilizer tank 44, and a second stabilizer tank 4.
(2) A replenishment circulation system consisting of a replenishment pump 46, a circulation pump 47, and a liquid temperature adjustment tank 48 having an internal heater located below each of the above-mentioned treatment tanks; (3) Further below the above treatment tanks. Developer fL supply tank 498, bleach-fix solution supply 449B1
It is composed of a supply/drainage tank group consisting of a stable liquid supply tank 49C and a drainage tank 49D, a drive system, and a conveyance system. +iif The sheet-like photosensitive material S fed from the paper feed section 20 and the conveyance section 30 is subjected to color development and fog exposure in the developing tanks 41 and 42 to form a developed image on the photosensitive surface of the photosensitive material S. After being subjected to bleach-fixing treatment in the bleach-fixing tank 43, the photosensitive material S is stabilized with a water-washing substitute stabilizing solution in the first stabilizing tank 44 and the second stabilizing tank 45. 50 conveyor rollers 5
1. The sheets are transported by a transport wire 52, the upper and lower surfaces are dried by a hot air dryer 53, and the sheets are discharged and stacked from a discharge roller 54 onto a discharge tray 55 provided outside the machine. FIG. 12 shows processing L11! of a conventional automatic developing processing apparatus. Figure 1 shows the liquid replenishment circulation system. Development a in developer supply tank 49^ CO1 and V bleach constant; n? l! The bleach-fixing process in the replenishment tank 49 [1 is carried out through a replenishment pipe 46 and a circulation pump 47, a liquid temperature adjustment tank 48, and a developer tank 41, 42, respectively.
A certain amount is replenished into the bleach-fixing tank 43. Further, the developer CD in the developer tanks 41, 4Z is sucked out from the developer 4fi41 by the circulation pump 4), mixed with the newly supplied developer CD in the circulation pump 47, and the solution temperature is adjusted again! It is refluxed into the developing tank 42 through the 1i tank 48. Similarly, during bleaching, the bleach-fix solution inlet F in the fixing tank 43 is also circulated through the circulation pump 47, the solution temperature 1181, and the regulating tank 48, and during this time, the solution is mixed with a new replenishing solution and refluxed into the bleach-fix tank 43. Each of the above treatment tanks 41, 43, and 44 has an over 70-tube 4
11, 431, and 441 are provided respectively to maintain the liquid level of each processing tank constant. Each of the above J! I! Tanks 41, 4: (. In 44, new replenishment processing liquids are stored in replenishment tanks 49^, 49B, and 49C to compensate for the deterioration of each processing liquid CD, BF, and Sll.
A fixed amount f is replenished from As a result of this replenishment, the amount of processing liquid in the processing tank increases, a part of which flows into the over 70-pipe, passes through the tube, and drains into the drain tank 49Da+490b+4.
It is housed within 9Dc. These drain tanks are replaced with empty ones when the drain reaches G13 cups. On the other hand, the treatment liquid in the treatment tank has a limited treatment capacity even if the above-mentioned treatment capacity restoration measures are taken, and impurities and waste products may settle or become turbid, causing the entire amount of treatment liquid to be replaced with new liquid. It will be necessary to replace it with At this time, the pulp provided outside each processing tank is plugged with IJII, and the entire amount of each processing liquid flows into and is stored in the external tanks 49Ea, 49Eb, and 49Ec, and the empty processing tank and the internal conveyance roller group etc. After taking it out and washing it with water, a new treatment 1! l! Fill with liquid. This place J! l! The simultaneous liquid exchange must be performed at regular intervals or every time a predetermined number of sheet-like photosensitive materials are processed. In addition, it takes a long time to develop the photosensitive material,
The long transport distance and therefore the large number of transport rollers used inside and outside the processing tank, which must be rotated at a constant speed, have made the I fastest apparatus complex and expensive. In particular, when developing a thin photosensitive material, a larger number of conveying rollers are required. This is because the resistance of the processing liquid tends to cause the tip to deviate from the direction of travel of the photosensitive material. Furthermore, each of the processing tanks has 5 rack members! Since the processing tank contains many rollers, ID plates, etc., it is difficult to find and remove the photosensitive material that is jammed in the processing tank. For this reason, it is necessary to pull up the rack member from the processing tank and check the inside of the processing tank or the rack member, and this must be done for each processing tank. Such work requires time and effort, and also causes troubles such as spillage, scattering, and contamination of the processing liquid. In addition, a large volume of processing liquid can be kept at a constant temperature (for example, 38°C ± 0°C).
．． C), it takes a long time to warm up and consumes a lot of power. [Problems to be Solved by the Invention] In a developing processing apparatus having processing tanks as described above, not only does the apparatus become complicated and large because of each processing tank and rack members such as transport rollers, but it is also difficult to replenish processing liquid. ,Circulation,
The equipment becomes complicated due to wandering, replacement, etc., and the labor required for this is also large, which can lead to trouble. It is also difficult to handle paper jams.

[Means to solve the problem]

The main purpose of the present invention is to eliminate such drawbacks in the conventional technology and to prevent changes in finished image quality due to deterioration and deterioration of the processing solution, and also to simplify the development processing apparatus, improve work efficiency, and facilitate troubleshooting. The purpose of this is to reduce speed, zooming time, and power consumption. The automatic developing section 31 of the present invention achieves the above object! , the apparatus is an automatic processing apparatus that automatically develops an exposed photosensitive material with a processing solution such as a developer, a bleach-fix solution, a stabilizer, etc., in which the above-mentioned processing J!
A rotatable applicator roll that applies the JJ liquid, a rotatable opposing roll that conveys the photosensitive material in contact with it from the back side of the photosensitive surface, and a rotatable opposing roll that is placed close to the applicator roll and coats the circumferential surface of the applicator roller. The apparatus is characterized in that it comprises a processing liquid discharging means for uniformly applying the processing liquid, and a processing liquid supply means for supplying the processing liquid to the discharging means. DESCRIPTION OF THE PREFERRED EMBODIMENTS The detailed practical application of the present invention will now be described with reference to illustrated embodiments. Note that the present invention is not limited to the aspects of this embodiment. FIG. 1 is a cross-sectional view showing the overall structure of an automatic processing apparatus according to the present invention. In the figure, the block unit placed on the leftmost side is the first developing section 100, the second block unit adjacent to it on the right side is the second developing section 200, and the third block unit on the right side is the transport ff1s. It is 300. Continuing to the right, a bleach-fixing section 400, a first stabilizing section 500,
A second stable section 600 and a transport section 70-O are arranged. These seven block units constitute a development processing section. Also, on the right side of the transport section 700,! 510
A drying section 50 having a structure similar to that shown in the figure is arranged.
A one-dot line passing through the center of the seven block units is a conveyance path through which the sheet-like photosensitive material S passes. The reversal type photosensitive material used in the present invention is a photosensitive material in which a positive image is formed through exposure and development processing, and is used to obtain high-quality copied images, especially color copied images. , a silver halide photographic light-sensitive material is used. Suitable examples of such silver halide photographic materials include internal latent image type or other direct reversal type silver halide photographic materials, and reversal type (reversal development type) silver halide photographic materials. Further, the support (base) of the silver halide photographic light-sensitive material may be opaque paper or the like or a transparent film. Further, the silver halide photographic material may be either color or black and white. In the copying apparatus shown in FIG. 8, the silver halide photographic light-sensitive material is drawn out from the paper feed section 20 and made into a sheet, and delivered to the conveyance section 30, where the image exposure section 10 exposes and scans the original image. A latent image is formed on the photosensitive surface. Thereafter, the sheet-like photosensitive material S is sent to the first developing section 100 of the developing processing section. At this time, the sheet-like photosensitive material S is inserted and conveyed into the feed opening of the first developing section with the photosensitive surface facing upward. The first developing section 100 includes a developing wL coating roll 101 and a developer discharging means 110 arranged above the photosensitive surface, and a counter roll 102 and a water coater RI 120 arranged on the lower surface side of the sheet-like photosensitive material S. It is composed of force and et al. Further, the second developing section 200 similarly includes a developer application roll 2.
01, developer discharge means 210. It is composed of a facing roll 202, a water application means 2201, and a second exposure means 230. FIG. 2 is a perspective view showing the main parts of the first developing station 100. As shown in FIG. The developer application roll 101 is rotatably supported on the wall surface of the unit housing 103. A drive tooth 111104 fixed to the shaft end of 01 is connected to a drive source (not shown) (
It is rotated by being rotationally driven by a motor). The opposing roll 102 is rotatably supported in detail by two levers (not shown), and a driven tooth $105 fixed to the shaft end of the roll 102 meshes with the drive gear 104 to rotate at the same speed as the coating roll 101. It is rated as 1 grade. A gap is provided between the applicator roll 101 and the opposing roll 102, which is equal to the thickness of the photosensitive material and the thickness of the coating liquid layer by 4'1, so that the liquid does not run out. The facing roll 102 was brought close to the coating roll 101 so that the water on the facing roll 102 came into contact with the coating roll. The developer discharging means 110 is removably fixed to the housing 103 in parallel with the rotation axis of the coating roll 101. The developer discharge means 110 consists of discharge members 112 and 113 fixed to a fixture 111. FIG. 3(^) shows a perspective view of the discharge means 110, and FIG. 3(B) shows a perspective view of the discharge member 113. The above-mentioned discharge member consists of an upper discharge member 112 and a lower discharge member 113 which are brought into close contact with each other at the joint surface at the center of the dowel, and has a tunnel-shaped developing solution circulation passage 114 formed therein. The front wall surface of the discharge members 112 and 113 has a predetermined width of m.
A wide slit-shaped nozzle 115 is opened, and the inside of its Il1 opening communicates with the flow path 114. Further, an opening 117 is formed in the bottom of the lower discharge member 113 on the north end side of the inlet portion 11B of the flow path 114,
It is connected to tube 118. In the third section 1 (8), a line Sr1 indicates the flow direction of the developer. The developer sent from the inlet portion 116 passes through the flow path 114 and is discharged from the slit-shaped nozzle 115 in a constant layered manner. Note that a valve means 119 is connected to the pipe 118, and since the valve means is normally a "pitch", the developer does not flow out through the pipe 118. Only when cleaning the flow passage 114, the valve means is opened to allow cleaning water to flow into the flow passage 114 and discharge it to the outside through the pipe 118. FIG. 4 is a sectional view of the developer discharge means connected to the developer supply means. The developer supply means is a device for supplying the developer to the developer discharge means, and is composed of a pedestal portion 120 and a developer container 130. There is a tapered recess ff1s122 on the two sides of the cradle 121 of the pedestal part 120, and the developer liquid 'fl container 13
It has a clearance so that the cap member 132 of No. 0 can be easily attached and detached. A tapered outflow passage 123 is provided at the bottom of the opening g122.
is connected to. The right end of the outflow passage 123 [1 part 1
24 is connected to the inlet portion 11G of the flow path 114 of the discharge member. 125 is a packing member that connects and fixes the outlet ff1S124 of the pedestal 121 and the inlet portion 116 of the discharge member to prevent leakage of liquid, and 126 is a fixture that fixes the packing member to the support 127. . Further, 128 is a side plate for positioning the developer container 130. Next, FIG. 5 shows an exploded partial perspective view of the developing 'tL container 130. In the figure, the developer container 130 is the container main body 13
1, cap 132, plunger 133, coil spring 1
34, and a spring support plate 135, all of which are made of a material that cannot be immersed in a processing solution such as a developer. The container body 131 is a closed container capable of containing a predetermined amount of developer, and a male thread 131B is formed in the lower processing liquid outlet opening 131^. The cap 132 has a female thread formed inside thereof to be screwed into the male thread 13113 of the lead-out opening 131^, and an opening at the lower end is tapered, and the plunger (movable plug) is inserted into this tapered opening. The tapered portion of the member) 133 fits tightly. A small hole or small notch 133A is provided in the 7-run portion of the planter 133, and communication between the opening at the lower end of the cap 132 and the inside of the container is possible through the small hole or small notch 133^. In addition, the cap 132
A support plate 135 is fixed and integrated with the inner wall surface of the main body. Since a fill spring 134 is compressed and built in between the spring support plate 135 and the plunger 133, it is not possible to simply turn the developer container 130 upside down.
The tapered portion 33 is tightly fitted to the tapered portion of the cap 132, and the developing QCD inside the container body 131 does not leak to the outside. With the developer container 130 inverted, the pedestal 12
When the cap 132 is dropped into the recess i 122 of No. 1, the protrusion 111s 129 provided at the bottom of the recess g 122 pushes up the plunger 133, and the fitting of the tapered portion separates to create a gap, so that the container body Developer CD in 131
The water passes through the hole in the support plate 135 and the small hole or small notch 133^ in the plantar 133, and further passes through the gap between the two tapered parts, flows out to the bottom of the recess 122, and flows out from the outflow passage 123 into the discharge member 112. , 113 flow path 114
, and is further discharged from the nozzle 115 to the outside, and is developed onto the circumferential surface of the rotating application roll 101 arranged in close proximity.
A thin liquid layer of CD is formed. The developing solution CD is replenished from the closed container 130 to the application means side, and the developing solution [As the remaining amount of CD decreases, the container 13
The upper air pressure inside the container 130 decreases, and the cap 13 of the container 130
2 and the recess 122 of the pedestal 121, outside air flows into the container 130. However, since the small hole or small notch 1338 provided in the 7th run part of the planter 133 acts to limit and alleviate the amount of air flowing in, the outside air can enter the container 130 and further into the flow path 123.
, 114 will not be subjected to large vibrations.
Note that the air amount limiting small hole or small notch is located on the support plate 1.
A similar effect can be obtained even if it is provided at 35. Pt56 diagram shows the above-mentioned first developing section 100 and second developing section 2.
00, and FIG. 7 is a partially enlarged sectional view thereof. Moreover, FIG. 8 is an external perspective view of the developer application section. As shown in the explanatory diagram of PtS7, the developer CD in the flow path 144 is discharged from the nozzle 115 and adheres to the hydrophilic circumferential surface of the coating roll 101 that rotates in opposition to it in a uniform layer thickness. The photosensitive material S is uniformly coated on the photosensitive surface of the photosensitive material S conveyed to any nipping position of the opposing rolls 102, and then sent in the direction of the arrow. Here, reference numerals 106 and 107 are guide plates for feeding the photosensitive material in a predetermined direction. On the other hand, water application means 140 is provided below the opposing roll 102. The water application means 140 consists of a water tank 141 containing water, a lifting means (not shown) for moving the water tank 141 up and down, and a water supply means (not shown) for supplying water into the rising water tank 141 and keeping it at a constant water level. . That is, when the water tank 141 rises, the water surface in the water 4fll 141 reaches the opposite roll 102.
Immerse the surrounding surface of the material to make it wet. As a result, dirt caused by the developer crystallized on the application roll 101 is cleaned by application of water by the opposing roll 102. Note that since the back side of the photosensitive surface of the photosensitive material S does not contribute to development, no problem occurs even if the counter roll 102 wet with water comes into contact with the back side of the photosensitive surface. On the other hand, a heater 106 and a temperature sensor (not shown) are fixedly installed above each unit body 103.203 of the first developing section 100 and the tjS2 developing section 200. For example, a red-hot sheathed heater or the like is used, and a resistance thermometer or the like is used as the temperature sensor. In the coating and developing method, although it is difficult to control the temperature of the developer CD in the container body 131, it is difficult to control the temperature of the developer CD in the container body 131. The developing solution CD is maintained at a constant temperature by controlling the ambient temperature. This promotes and stabilizes the reaction of the developer. Next, in the second developing section 200, the coating roll 20
1. The facing roll 202, the developer discharge means 210, and the water application means 2401 have the same structure and operation as the first developing section 100, but the second n-light means 250 is fixedly installed on the upstream side of the application roll 201. ing. The Pt52 exposure means 250 is
It consists of a cold cathode space 251 connected to the :rl source, a color filter 252, a transparent lath plate 253, and a light shielding wall 254 that accommodates these and is fixed to the casing 203. Note that 206 and 207 are side plates of the photosensitive material S. Further, the water application means 240 is shown in a lowered state, and the water surface is separated from the circumferential surface of the opposing roll 202. The bleach-fixing 'XJ@400 is also manufactured in the same way as the first developing section 100, and consists of a coating roll 401, an opposing roll 402, a bleach-fixing 7J liquid discharging means 410, a water application means 440, and a bleach-fixing liquid supplying means. Furthermore, a heating element 450 is provided upstream of the application roll 401. The heating element 450 is made by uniformly winding a nickel and chromium ribbon wire around heat-resistant mica, wrapping the J8 edge with mica, covering this with a metal plate, and then press-molding it with a press machine to form a strip. It is a flat plate type heating element. A unit of a conveying section 300 is provided between the bleach-fixing section 400 and the second developing section 200, and includes conveying rollers 301 and 302 that rotate at every speed and a heating element 350. Note that 303 and 503 are temperature sensors provided at the bottom of each side plate of the conveyance section 300 and the Pt51 stabilization section 500,
For example, it is a resistance thermometer, which measures the ambient temperature during development and bleach-fixing reactions to adjust the temperature. A heater 406 is fixedly installed above the conveying section 300 and the bleach-fixing g400. Further, a tjS1 stabilizing section 5 is provided downstream of the bleach-fixing section 400.
00 and second stable ff1S600 units are fixedly installed. Like the first developing section 100, the first stabilizing section 500 is provided with a coating roll 501, a counter roll 502, and a stabilizing liquid discharging means 510. Similarly f52 stable ff1
s 600 includes a coating roll 6゜1 and an opposing roll 602.
, a stabilizing liquid discharge means 610 is provided. Adjacent to this second stable ff1s 600 is a transport section 700.
are provided, and internal conveyance rollers 701 and 702 squeeze the photosensitive material that has been stabilized in the 12 stabilizing section 600 and send it to the drying section 50 adjacent to the right. The drying ff550 includes a conveyance roll 51, a conveyance wire 52,
It is composed of a hot air dryer 553 and a discharge roll 54. Next, the operation of the automatic processing apparatus having the above structure will be explained with reference to FIG. First, when the main switch (not shown) is turned on, the heaters 106, 406, and 506 start generating heat, reach a predetermined temperature, and enter a standby state. Next, when the copy button is pressed, the photosensitive material is sent out from the conveying section 30, the original image is exposed and scanned at the imaging position ra18, and then sent into the automatic development processing station VC. First, in the first developing section 100 of the unit, a developing QCD having a constant liquid thickness is uniformly applied to the exposed photosensitive material S in the atmosphere as described above, and development proceeds. At this time, the lower opposing roll 10
Since the photosensitive material S is wetted by the water application means 140, the back surface of the photosensitive material S is wetted with water and swollen by immersion. Subsequently, in the second exposure means 250, the illumination light from the cold cathode tube 251 is transmitted through the color filter 252, and the color A! is,

The developing solution CD is uniformly applied onto the photosensitive material S by the roller 0, the coating roll 201, and the opposing roll 202, thereby promoting development. Next, it is sent to the bleach-fixing section 400 via the conveying section 300. During this time, the heating elements 350 and 450 promote and stabilize the developing reaction. In the bleach-fixing section 400, a bleach-fix solution n is applied onto the photosensitive surface of the photosensitive material S by a coating roll 401, an opposing roll 402, a bleach-fix solution discharge means 4501, and a water application means 440.

Here, reference numeral 500 denotes a conveying section comprising a roll and a guide plate for conveying the photosensitive material S from the bleach-fixing section 400 in the lower tank to the first stable section 600 in the upper layer. In addition, fjS1 stable part 600. The second stabilizing section 700 is composed of a processing tank a, an idle roller, a guide plate, and a squeeze roller at each outlet, and the photosensitive material S sent into the stabilizing liquid tank is immersed here and stabilized. It is washed with water and sent to the next drying section 50. In the drying section 50, the wet photosensitive material S after washing with water is dried by a stream of hot air as it passes through this section. The photosensitive material S that has passed through the drying section 50 is conveyed upward along the conveyance guide plate and by the rotating conveyance rollers, and is then reversed and discharged onto the paper discharge tray 800 . Effects of the Invention As described above in detail, the automatic processing apparatus according to the present invention discharges each processing solution from a nozzle onto a coating roll and exposes it to light in the atmosphere when performing at least development processing and bleach-fixing processing. Apply uniformly over the material surface.
