[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a photosensitive material processing apparatus for developing a film accommodated in a film container.
[0002]
[Prior art]
Conventionally, a 135-size negative film that is generally used is developed by removing the negative film from the spool shaft (or cutting it in the vicinity of the spool shaft) and transporting a plurality of processing tanks with transport rollers or the like. ing.
[0003]
Further, the developed negative film is cut every predetermined number of frames and returned to the customer as a piece negative.
[0004]
In recent years, there has been proposed a new system for returning a developed negative film in a state of being accommodated in a cartridge without cutting the negative film.
[0005]
In this new system, the negative film is taken out from the cartridge deposited by the customer and developed, and the developed negative film is accommodated in the original cartridge and returned to the customer.
[0006]
[Problems to be solved by the invention]
By the way, when developing a small amount of negative film, conventionally, the cartridge was disassembled and the negative film inside was cut and cut in the vicinity of the spool shaft, and the separated negative film was weighted and stored in the processing tank. A method of soaking in a solution (so-called hanging development) has been taken.
[0007]
In the new system, when the conventional suspension developing system is used, a device for removing the negative film contained in the cartridge from the spool shaft without disassembling the cartridge, and a device for engaging the developed negative film with the spool shaft of the cartridge Are required, and the development processing system becomes complicated.
[0008]
Here, in order to solve the above problem, there can be considered a method in which the negative film fed out of the cartridge is immersed in the processing liquid in the processing tank while the film end is locked to the spool shaft.
[0009]
Further, in a large apparatus such as an automatic developing machine, there is a problem that the processing tank becomes large because the negative film is conveyed by a roller.
[0010]
On the other hand, the suspension development method does not require a transport roller or the like, and thus the opening area of the processing tank can be made relatively small.
[0011]
However, the suspension development method has a problem that the processing must be performed while stirring the processing liquid by shaking the negative film up and down in order to prevent uneven development. Furthermore, even with the suspension development method, if a processing tank is provided for each processing solution, there is still a problem that the processing tank takes up space.
[0012]
In consideration of the above facts, an object of the present invention is to provide a photosensitive material processing apparatus capable of appropriately developing a new system film without taking time and effort.
[0013]
[Means for Solving the Problems]
The invention described in claim 1 is a photosensitive material processing apparatus for developing a long film, and has a sheath-like processing tank having a film insertion opening that allows the film to be taken in and out only in the longitudinal direction. The film slot Press with the pressing member Closing means for closing, a processing liquid inlet / outlet provided at both ends in the longitudinal direction of the processing tank, and a processing liquid supply connected to the processing liquid inlet / outlet for circulating, replacing, and discharging the processing liquid in the processing tank And a stirring means for stirring the processing liquid in the processing tank.
[0014]
In the photosensitive material processing apparatus according to claim 1, a long film is inserted into a sheath-like processing tank from a film insertion port, Press the film insertion slot with the pressing member of the closing means Close the film insertion slot. In the case of the film of the new system, the film can be sent out from the cartridge, and the film fed out can be inserted into the processing tank without being separated from the cartridge.
[0015]
Thereafter, the processing liquid is supplied into the processing tank from one processing liquid inlet / outlet, the processing liquid discharged from the other processing liquid inlet / outlet is returned to the one processing liquid inlet / outlet again, and the processing liquid is moved along the longitudinal direction of the processing tank. Circulate. At this time, the processing liquid in the processing tank is stirred by the stirring means, thereby generating turbulent flow and preventing uneven processing of the film.
[0016]
The photosensitive material processing apparatus of the present invention does not require a device for separating or joining the film from the spool shaft of the cartridge, and further does not require a transport roller for transporting the film, so that the processing tank can be reduced in size. The photosensitive material processing apparatus can be downsized.
[0017]
When the film is a color negative film, for example, color development is first performed with a color developer, then bleach-fixing is performed by replacing the bleach-fixing solution, and then rinsing is performed by replacing the rinse solution. By performing the processing and discharging the rinse solution, the development processing of the film is completed.
[0018]
Moreover, it is preferable that the dimension (thickness) of the direction along the thickness direction of the film in a processing tank shall be 20 to 200 times the thickness of a film. If it is less than 20 times, the amount of the treatment liquid may be insufficient, and if it is more than 200 times, the treatment tank will be stored larger than necessary and the treatment tank will be enlarged.
[0019]
Moreover, the dimension of the direction along the thickness direction of the film in a processing tank is good also as the direction of the part corresponding to the width direction center part of the film larger than the part corresponding to the width direction both ends of a film. Thereby, the image area and the inner wall formed in the central part in the width direction of the film are separated from each other, and the image area can be prevented from being damaged. In this case, the dimension (thickness) in the direction along the thickness direction of the film in the treatment tank is 20 to 200 times the thickness of the film at the center in the width direction of the film, and the film corresponds to both ends in the width direction of the film The thickness is preferably 2 to 5 times the thickness.
[0020]
According to a second aspect of the present invention, in the photosensitive material processing apparatus according to the first aspect, the stirring means has a cross-sectional shape changing means for changing a cross-sectional shape in the tank.
[0021]
In the photosensitive material processing apparatus according to the second aspect, the sectional shape changing means changes the sectional shape in the tank. For example, it is possible to cause a flow in the processing liquid by reducing a part of the cross-sectional shape and greatly changing another part of the cross-sectional shape. By alternately increasing or decreasing the size, the processing liquid in the processing tank can be stirred.
[0022]
According to a third aspect of the present invention, in the photosensitive material processing apparatus according to the second aspect, the cross-sectional shape changing means includes a flexible wall formed of a flexible member on a part of the inner wall surface of the processing tank, And deforming means for deforming the flexible wall.
[0023]
In the photosensitive material processing apparatus according to the third aspect, the sectional shape in the tank can be changed by deforming the flexible wall by the deforming means, whereby the processing liquid in the processing tank can be agitated.
[0024]
According to a fourth aspect of the present invention, in the photosensitive material processing apparatus according to the third aspect, the flexible wall is provided on one side and the other side in the width direction of the processing tank.
[0025]
5. The photosensitive material processing apparatus according to claim 4, wherein the flexible wall is deformed by the deforming means so that the cross-sectional area in the processing tank on one side in the width direction is small and the cross-sectional area in the processing tank on the other side in the width direction is large. be able to. As a result, the treatment liquid in the treatment tank can be flowed along the width direction of the treatment tank and stirred.

(Function)
Next, the operation of this embodiment will be described.
[0126]
First, the customer loads the cartridge 14 containing the undeveloped film F into the recess 150 of the empty station 110 and closes the cover 148.
[0127]
When the cartridge 14 is loaded, the barcode 80 of the cartridge 14 is read by the barcode scanner 107, the main controller 202 determines how many sheets of film F are taken, calculates the development fee and the printing fee, The total amount is displayed on the display device 114.
[0128]
Note that the display device 112 on the side of the station 110 loaded with the cartridge 14 displays the time (waiting time) until the printing is completed or the finishing time.
[0129]
When the customer inserts the amount displayed on the display device 114 from the charge input unit 104, the ID card 118 is issued from the ID card entrance 120 (note that the change goes out to the tray 116).
[0130]
In the ID card 118, a reception number, a reception time, a finishing time, an identification number of the station 110 loaded with the cartridge 14, an ID number of the cartridge 14, the number of shots, and the like are recorded (printing, magnetic recording, etc.).
[0131]
The station 110 loaded with the cartridge 14 moves from the opening 108 into the casing 102 and stops at a predetermined position of the development processing unit 128. When the station 110 moves, the upper guide 310 and the lower guide 306 of the movable film guide 302 are retracted away from each other so as not to hit the station 110.
[0132]
When the station 110 stops, the chucking device 162 is activated, and the door driver 158 engages with the key hole 34 of the door shaft 32 and the spool driver 160 engages with the key hole 62 of the spool shaft 16.
[0133]
The cylinder 312 is driven, and the lower guide 306 and the upper guide 310 approach each other so that the roller 304 and the roller 308 can guide the film F to the processing tank 300.
[0134]
Next, in the station 110, after the motor 164 is rotated and the door 30 is opened, the spool driver 160 is rotated and the film F is sent out from the insertion port 28 of the cartridge 14.
[0135]
The film F fed from the cartridge 14 passes between the rollers 304 and 308 of the lower guide 306 and the upper guide 310 and is inserted into the processing tank from the opening of the processing tank 300. When the film F is inserted into the processing tank 300, the block 322 of the sealing device 320 is separated from the cutout portion 318 by a predetermined dimension. When the film F has been inserted into the processing tank 300, the block 322 is The notch portion 318 is pressed to seal the inside of the tank.
[0136]
Next, the development processing of the film F will be described.
The reducer 360 is charged with a color developer for one bottle in advance, and is heated to a predetermined temperature (45 ° C. in this embodiment) by the heater 362.
[0137]
When the inside of the tank is sealed, the pump 342 is driven, and the color developer stored in the reducer 360 is replaced with a pipe 358, a solenoid valve 338, a pipe 340, a pump 342, a pipe 344, a solenoid valve 346, a pipe 348, It is supplied to the processing tank 300 through the in-line ceramic heater 350, the pipe 352, the electromagnetic valve 354 and the pipe 356.
[0138]
When all the color developer in the reducer 360 is discharged, the solenoid valve 338 is switched, and the color developer in the tank is replaced with a pipe 336, a solenoid valve 338, a pipe 340, a pump 342, a pipe 344, a solenoid valve 346, and a pipe. 348, the in-line ceramic heater 350, the pipe 352, the solenoid valve 354, and the pipe 356 are circulated.
[0139]
When processing a photosensitive material such as a film with a processing solution, it is preferable to flow the processing solution in a turbulent flow with respect to the photosensitive material in order to prevent uneven processing. That is, when the processing liquid is circulated in the longitudinal direction of the processing tank 300, the processing liquid in the tank is almost laminar, and there is a concern that processing unevenness occurs in the width direction of the film F. For this reason, when the color developer is circulated along the longitudinal direction, the piston 602 is reciprocated by the cylinder 604. On the inner surface of the piston 602, a plurality of ribs 608 that are projected in a substantially semicircular shape are formed in the width direction, so that the flow in the width direction of the film F flows in the color developer in the tank when the piston 602 moves. As a result, a turbulent flow is generated in the color developer in the tank, and the color developer is well stirred. For this reason, the process nonuniformity of the film F can be prevented. Since the inside of the tank is sealed by the sealing device 320, the color developer does not leak out of the tank even if a pressure fluctuation acts during stirring. Thereby, the color development processing of the film F is appropriately performed.
[0140]
Note that the temperature of the color developer is kept constant by the in-line ceramic heater 350 so that the temperature of the color developer does not decrease during circulation. When the color developer is circulated in the tank, the turntable 368 is rotated by a predetermined angle so that a new bottle 370 is disposed above the punching device 376 and the bottle 370 disposed above by the punching device 376 is operated. The color developer is introduced into the reducer 360. This color developer is used for the next film F processing. In this case, the piston 602 is reciprocated while being circulated by the pump 342. However, the reciprocation of the piston 602 may be performed only by stopping the circulation. At this time, the treatment liquid may be small. Moreover, in order to prevent a temperature fall, you may heat the main body of the sheath-shaped processing tank 300. FIG. Further, circulation and stirring may be performed in the inching operation of the pump 342 and the piston 602.
[0141]
When the development processing of the film F is completed after a predetermined time has elapsed, the pump 342 is stopped, the electromagnetic valve 346 is switched, and the color developer in the tank and the piping is discharged to the drainage tank 390 via the piping 388. The
[0142]
When all the color developer is discharged after a predetermined time has elapsed, the solenoid valve 354 is switched and the pump 412 is driven, and the bleach-fix solution in the bleach-fix solution tank 400 is supplied with the pipe 416, the pump 412, the pipe 408, the electromagnetic It is supplied to the processing tank 300 through the valve 406, the pipe 404, the electromagnetic valve 354, and the pipe 356, and the bleach-fixing solution in the tank is further supplied to the bleach-fixing solution tank 400 through the pipe 392, the electromagnetic valve 394 and the pipe 396. Return and circulate. Further, when the bleach-fixing solution is circulated, the piston 602 is reciprocated by the cylinder 604, and the bleach-fixing solution in the tank is well stirred. Thereby, the bleach-fix process of the film F is performed appropriately.
[0143]
When the predetermined time has elapsed and the bleach-fixing process of the film F is completed, the pump 412 is reversed, and the bleach-fixing solution in the tank and the pipe is returned to the bleach-fixing solution tank 400. In addition, the liquid in the piping 392, the electromagnetic valve 394, and the piping 396 falls naturally.
[0144]
When the predetermined time has passed and the bleach-fixing solution is returned to the bleach-fixing solution tank 400, the pump 412 is stopped, the solenoid valves 406 and 394 are switched and the pump 414 is driven, and the rinse solution in the rinse solution tank 402 is The pipe 418, the pump 414, the pipe 410, the electromagnetic valve 406, the pipe 404, the electromagnetic valve 354, and the pipe 356 are supplied to the treatment tank 300, and the rinsing liquid in the tank further includes the pipe 392, the electromagnetic valve 394, and the pipe 398. Is returned to the rinse liquid tank 402 and circulated. Further, when the rinse liquid is circulated, the piston 602 is reciprocated by the cylinder 604, and the rinse liquid in the tank is well stirred. Thereby, the rinse process of the film F is performed appropriately.
[0145]
When the rinsing process for the film F is completed after a predetermined time has elapsed, the pump 414 is reversed, and the rinsing liquid in the tank and the piping is returned to the rinsing liquid tank 402. In addition, the liquid in the piping 392, the electromagnetic valve 394, and the piping 398 falls naturally.
[0146]
When the rinsing liquid in the tank is completely discharged after a predetermined time has elapsed, the pump 414 stops, the block 322 of the sealing device 320 is separated from the cutout portion 318, and the station 110 holding the cartridge 14 moves at a constant speed. To move in the direction of arrow B and stop at a predetermined position immediately before the end of the endless track 142 on the arrow B direction side.
[0147]
When the station 110 moves, the processed film F is sequentially drawn out of the tank, and when passing through the drying unit 130, the water absorbing paper 426 of the water absorbing device 420 absorbs moisture on the surface of the film F, and the drying fan 422 is heated. The film F is dried by blowing air.
[0148]
When the station 110 is stopped, the film F is wound up, and when the first image frame 64 on the cartridge 14 side is positioned at the opening of the negative carrier 450, the transport of the film F is temporarily stopped and the black shutter 464 is operated for a predetermined time to perform exposure. The image of the image frame 64 is printed on the photosensitive material 475. The image frame 64 can be stopped at the opening of the negative carrier 450 by detecting the perforation 66 of the film F with a sensor.
[0149]
The photosensitive material 475 on which the image has been printed is coated with water by the water coating unit 476 and then conveyed to the heat development transfer unit 136 in a state of being superimposed on the image receiving material 485 and is sandwiched between the laminating roller and the heating roller. The photosensitive material 475 and the image receiving material 485 are heated to a predetermined temperature. As a result, the movable dye of the photosensitive material 475 is released, and the released dye is transferred to the dye fixing layer of the image receiving material 485 to form an image on the image receiving material 485.
[0150]
Thereafter, the photosensitive material 475 and the image receiving material 485 are separated, and the used photosensitive material 475 is wound around the winding shaft 490.
[0151]
On the other hand, the image receiving material 485 cutter 494 on which an image is formed is cut to a predetermined size to form a so-called print 122 and falls into a basket 498 below.
[0152]
Thereafter, when printing of all the images is completed in the same manner, the spool driver 160 is rotated to wind up all the film F on the spool shaft 16 of the cartridge 14, and the door 30 is closed. When the door 30 is closed, the energization to the solenoid 170 is stopped, and the front ends of the door driver 158 and the spool driver 160 are separated from the cartridge 14.
[0153]
Thereafter, when the station 110 moves in the direction of arrow B and reverses at the end on the arrow B direction side of the endless track 142, the extrusion device 174 is operated to open the cover 148 and drop the cartridge 14 into the opening of the duct 500. Let The cartridge 14 passes through the duct 500 and falls into the basket 498 in which the print 122 is placed.
[0154]
When the print 122 is finished, for example, a message “print of reception number XX is finished” is displayed on the display device 114.
[0155]
Then, when the customer inserts the corresponding ID card 118 into the ID card entrance 120, the ID card 118 is verified, and the basket 498 in which the cartridge 14 and the print 122 are accommodated is moved to the inside of the automatic door 124, and the automatic door 124 is opened and the customer can remove the print 122 and cartridge 14 from the basket 498.
[0156]
In the printer processor 100 according to the present embodiment, the development processing is performed in the single processing tank 300 having the minimum necessary capacity, so that the space occupied by the processing tank can be minimized. Further, since an apparatus for separating or joining the film F from the cartridge 14 is not required, the printer processor 100 corresponding to the new system can be reduced in size and can be installed in a narrow space.
[0157]
In addition, since the color developer is disposable, the film F can be processed under optimum processing solution conditions.
