2. Description of the Related Art In wet processing of a photosensitive material, the photosensitive material is sequentially transported and immersed in a processing solution (for example, a developing solution, a bleaching solution, a fixing solution, washing water, etc.) stored in a plurality of processing tanks. It is done by doing.

Conventionally, in a photosensitive material processing apparatus for performing such processing, the upper portion of each processing tank is open and the level of the processing liquid stored in the processing tank is open to the atmosphere. Problems such as deterioration and deterioration of the treatment liquid due to evaporation, temperature decrease, and contact with air have occurred.

In order to solve this problem, in order to cover the liquid surface of the processing solution with a fluid layer such as paraffin, and to enable the photosensitive material to be carried into and out of the processing solution, A photosensitive material processing apparatus provided with an opening forming means for forming an opening in a fluid layer has been disclosed (Japanese Patent Application Laid-Open No. HEI 01-2001).

The processing solution may enter the adjacent processing tank and cause contamination. Particularly, the contamination between the developing solution and the bleaching solution (or the bleach-fixing solution) is a problem because the photographic property of the light-sensitive material is extremely deteriorated. When such contamination occurs, all of the processing liquid in the processing tank must be replaced, which requires labor, time, maintenance of an unprocessable state during replacement, economic efficiency, and an increase in the amount of waste liquid. It is not preferable in various points such as.

In recent years, due to the spread of photo processing systems, the expansion of applications, or the necessity of dealing with emergencies, a place other than a still place, for example, a vehicle, a ship, an aircraft, an elevator, etc. In some cases, a photosensitive material processing device such as an automatic developing machine or a wet copying machine may be installed.

As the pumps 23a to 23d, 27a and 27b, for example, a centrifugal pump, a diaphragm pump, a bellows pump and a roller pump can be used.

As the flow meters 24a to 24d, 28a and 28b, any type can be used as long as they can detect the amount of the processing liquid passing through the pipeline, and in particular, an integrating flow meter is preferable. , Impeller type, gear type, etc. may be used.

Further, each of the pipelines 22a to 22d, 26a, 2
One end of 6b is connected to, for example, the bottom of a predetermined processing tank among the processing tanks 2 to 7. In this case, it is preferable that the one end is connected via a detachable connector (not shown). Thereby, one end of each of the pipelines 22a to 22d, 26a, 26b can be selectively connected to any of the processing tanks 2 to 7, and the arrangement pattern of the processing liquid in the processing tanks 2 to 7 and The composition, the flow direction of the processing liquid between the processing tanks, and the like can be appropriately selected and changed.

Such selection and change may be made in accordance with the type of the photosensitive material S to be processed and the processing conditions. The photosensitive material processing apparatus 1 may be used for moving objects such as vehicles, ships, aircrafts, and elevators, which will be described later. In the case of installation, it can be set individually to suit each moving object, which is advantageous. For example, for photosensitive material processing equipment installed in vehicles and aircraft for news and coverage, the piping configuration is such that rapid processing is possible, and photosensitive material processing equipment mounted on ships that require long voyages For this, a piping configuration that can further reduce the replenishment amount and the waste liquid amount of the processing liquid can be adopted.

Next, the operation of the processing liquid replacement device 20 will be described.

In synchronization with the processing of the photosensitive material S, replacement of the processing solution in each processing tank, that is, supply and discharge of the processing solution, is performed.

First, the supply and discharge of the developer will be described. When a signal for operating the pump (hereinafter referred to as a pump operation signal) is output from the control means 30, this pump operation signal is transmitted to the pumps 23a and 27a via lines 33a and 37a, respectively. The pumps 23a and 27a start driving almost simultaneously. As a result, new developer in the liquid storage space 21a is transferred to the conduit 2
2a, the exhausted developer in the developing tank 2 is sucked, and the drained tank 25 is drained through the pipe 26a.
Will be introduced.

At this time, the amount of the processing liquid that has passed through the pipe 22a (the processing liquid supply amount) and the amount of the processing liquid that has passed through the pipe 26a (the processing liquid discharge amount) are respectively determined by the flow meter 24a. And 28a, and this information is input to the control means 30 via lines 34a and 38a, respectively, and is processed. The processing liquid supply amount and the processing liquid discharge amount detected and measured by the flow meters 24a and 28a correspond to the appropriate amounts (target values) of the processing liquid supply amount and the processing liquid discharge amount stored in the memory of the control unit 30 in advance. Be compared.

When the supply amount of the processing liquid becomes an appropriate amount (when the target value is reached), a signal (hereinafter referred to as a pump stop signal) for stopping the operation of the pump is output from the control means 30. The signal is transmitted to the pump 23a via the line 33a, and the pump 23a stops.

At the time when the discharge amount of the processing liquid becomes an appropriate amount (at the time when the target value is reached), a pump stop signal is output from the control means 30, and this pump stop signal is transmitted to the pump 27a via the line 37a. Then, the pump 27a is stopped.

The target value of the supply amount of the processing liquid is substantially equal to the target value of the discharge amount of the processing liquid, or is smaller than the target value of the discharge amount of the processing liquid in consideration of the reduction of the developing solution due to the taking out of the photosensitive material S. It is preferable to set a slightly larger value.

Next, the supply and discharge of the processing liquid other than the developing liquid will be described. When a pump operation signal is output from the control means 30, the pump operation signal is output to the lines 33b to 33b.
3d and 37b, pumps 23b-2
3d and 27b, and these pumps 23b-
23d and 27b start driving at substantially the same time. Thereby, a new bleaching liquid in the liquid storage spaces 21b to 21d,
The fixer and the washing water are respectively provided in the conduits 22b to 22d.
The bleach-fixing solution is supplied to the bleaching bath 3, the fixing bath 5 and the washing bath 7 via the
The liquid is introduced into the drainage tank 25 through the pipe 26b.

As shown by the arrow in FIG. 2, when the washing water is supplied into the washing tank 7, the increased amount of the washing water causes the photosensitive material S to pass between the blades 16 of the passage 15d for movement between the tanks. In this case, the water flows into the washing tank 6 through a slight gap (hereinafter referred to as a blade gap) between the blades 16 formed near both ends of the photosensitive material S in the width direction, and further, the washing water in the washing tank 6 is washed. The water flows into the fixing tank 5 through the gap between the blades of the inter-tank transfer passage 15c. The fixing bath 5 is supplied with washing water from the gap between the blades and a fixing solution (which may be a concentrated solution of the fixing solution) from a pipe 22c. It flows into the bleach-fixing tank 4 through the gap of the blade 15b.

On the other hand, when the bleaching solution is supplied into the bleaching tank 3, the increased amount of the bleaching solution flows into the bleach-fixing tank 4 through the gap between the blades of the inter-tank moving passage 15a.

Thus, in the bleach-fixing tank 4, the bleaching solution and the fixing solution are supplied from the adjacent bleaching tank 3 and the fixing bath 5, respectively, and these are mixed to form a bleach-fixing solution.
Then, the increased amount of the bleach-fixing solution is discharged out of the tank via the pipe 26b.

In supplying and discharging the processing liquid, the amount of the processing liquid passing through each of the pipes 22b to 22d (the processing liquid supply amount) and the amount of the processing liquid passing through the pipe 26b (the processing liquid) Emission amount) is measured by the flow meters 24b-2
4d and 28b, detected and measured, this information
The signals are input to the control means 30 via the lines 34b to 34d and 38b, respectively, and are processed. Flow meter 24
The processing liquid supply amount and the processing liquid discharge amount detected and measured by b to 24d and 28b are appropriate amounts (target values) of the processing liquid supply amount and the processing liquid discharge amount stored in the memory of the control unit 30 in advance. Is compared to

At the time when the supply amount of the processing solution in each of the bleaching solution, the fixing solution, and the washing water becomes an appropriate amount (at the time when the target value is reached), a pump stop signal is output from the control means 30. Are transmitted to the pumps 23b to 23d via the lines 33b to 33d, respectively, and the predetermined pumps 23b to 23d are stopped.

When the discharge amount of the processing liquid becomes an appropriate amount (at the time when the target value is reached), a pump stop signal is output from the control means 30, and this pump stop signal is transmitted to the pump 27b via the line 37b. Then, the pump 27b is stopped.

The sum of the target values of the processing solution supply amounts of the bleaching solution, the fixing solution, and the washing water is substantially equal to the target value of the processing solution discharge amount, or the amount of the developer brought in by the photosensitive material S and the washing. It is preferable to set the value in consideration of the difference in the amount of water taken out.

When the replenisher tank 21 becomes empty, it is replaced with a new replenisher tank 21. When the drainage tank 25 becomes full, the processing liquid waste liquid in the tank is discharged to the drainage tank 2.
5 is discarded, and a new empty drainage tank 25 is set.

The composition and pH of the mother liquor of the processing solution in each of the processing tanks 2 to 7 and each replenisher in the replenisher tank 21 are not particularly limited, and are appropriately selected according to the type of the photosensitive material S to be processed. do it.

Table 1 below shows preferable values of the supply amount (replenishment amount) of each processing solution.

[0066]

[Table 1]

In the present invention, as described above, the evaporation, deterioration and deterioration of the processing solution are suppressed, and no contamination of the processing solution occurs. The amount is as small as about 50 to 90%, and as a result, the amount of waste liquid is also small.

The treatment liquid replacement device 20 is not limited to the configuration shown in the drawing, and in particular, the arrangement pattern of the pipelines can be arbitrary. For example, drainage is also performed from the washing tank 6,
It is also possible to adopt a configuration in which washing water does not flow into the fixing tank 5, or a configuration in which the processing liquid is supplied and discharged to each of the processing tanks 2 to 7.

In the photosensitive material processing apparatus of the present invention, the type of the photosensitive material S to be processed is not particularly limited, and may be color or black and white. For example, a color negative film, a color reversal film, a color positive film, a color photographic paper, a color reversal photographic paper, a black-and-white negative film, a black-and-white reversal film, an X-ray photographic material, a black-and-white photographic paper, a black-and-white reversal photographic paper, a microfilm, etc. ,
The size is not particularly limited.

The light-sensitive material processing apparatus of the present invention is, for example, a large automatic developing machine, a small automatic developing machine (minilab), a wet copying machine, a printer processor, a video printer processor, a photographic print making coin machine, and a plate inspection machine. It can be applied to various photosensitive material processing devices such as color paper processing machines.

The photosensitive material processing apparatus of the present invention has been described above with reference to the illustrated structural examples, but the present invention is not limited to these. In particular, the configuration and arrangement of the processing tank are appropriately determined according to the type of photosensitive material to be processed and the like. For example, in the processing of color photographic paper, a developing tank,
It has a configuration in which three bleach-fixing tanks and a washing tank are juxtaposed.
Further, processing tanks for various purposes can be added, such as providing a preliminary washing tank or an adjusting tank between adjacent processing tanks, for example, between the developing tank 2 and the bleaching tank 3. Further, the lids 8 and 9 are not installed in all the processing tanks, but at least the necessary processing tanks (for example, a developing tank and a bleaching tank (bleach-fixing tank, fixing tank) that are highly required to prevent contamination). It may be installed only on one side).

[0072]

As described above, according to the photosensitive material processing apparatus of the present invention, since the upper opening of each processing tank is shielded by the lid, it is possible to prevent evaporation, deterioration and deterioration of the processing liquid. Therefore, the replenishment amount and the drainage amount of the processing liquid can be reduced. In addition, there is no need to provide a driving source or a mechanically movable part as a means for loading, unloading, and moving between the tanks, so that the structure is not complicated, the apparatus is not enlarged, and there is no failure. .

Furthermore, even when the photosensitive material processing apparatus is shaken or vibrated, the processing liquid does not suffer from contamination due to spillage of the processing liquid or deterioration of the processing liquid due to contamination, and good photographic properties can be stably obtained. For this reason, it is advantageous to install the photosensitive material processing apparatus of the present invention in a moving object such as a vehicle, a ship, an aircraft, an elevator, etc.
