Field of the Invention The present invention relates to a measuring rack for a photosensitive material processing apparatus for measuring an amount of cleaning water for cleaning an extra-liquid transport section for transporting a baked photosensitive material into a processing solution in a processing tank. .

[0002]

2. Description of the Related Art According to a printer processor, photographic paper is exposed and printed by a printer unit, and after printing, each process of development, bleach-fix, and washing is performed by the processor unit.
Subsequently, drying is performed in the drying section, and then discharged to the stock section.

[0003] The development, bleach-fixing, and washing processes are performed in processing tanks such as a developing tank, a bleach-fixing tank, and a washing tank, respectively.
Each processing tank is provided with a processing rack for transferring photographic paper into the processing liquid.

At the top of the processing rack, there is provided an extra-liquid transport section comprising rollers, guides, and the like for introducing photographic paper into the liquid and drawing out the photographic paper from the liquid for other processing. A crossover rack is provided outside the processing liquid.
The processing liquid slightly adheres to the extra-liquid transport unit when the photographic paper is transported. For this reason, if the operation is stopped for a long time, such as at night, after finishing work with the treatment liquid adhered, the treatment remaining on the photographic paper at the beginning of the next process will remain attached to the extra-liquid transport unit. The liquid may be transferred and become dirty.

[0005] To prevent this, it is necessary to remove the crossover rack at the end of work, wash the extra-liquid transport section, and remove the processing liquid adhering thereto. Then, after the cleaning, the crossover rack having the extra-liquid transfer section must be mounted again.

[0006] Therefore, an automatic cleaning apparatus capable of automatically cleaning the crossover rack without removing or mounting the troublesome crossover rack has been considered.

That is, the automatic cleaning apparatus has a structure in which a cleaning nozzle is provided in a crossover rack, and the cleaning nozzle sprays cleaning water toward the extra-liquid transport section for a predetermined time, and then rotates the roller for a predetermined time. Then, the washing water is sprayed for a certain time, and then the roller is inverted for a certain time. And it is such that washing is performed by repeating this several times.

On the other hand, since the concentration of a processing solution such as a developing solution or a bleach-fixing solution changes due to evaporation of water, an amount of water corresponding to the amount of evaporation is replenished in order to keep the concentration of the processing solution constant. There is a need. Therefore, it is conceivable that the supply of water is covered by the washing water for washing the extra-liquid transport unit, that is, the washing water is provided with an evaporation correction function.

In such a case, in order to keep the concentration of the processing liquid constant, it is necessary to accurately grasp the amount of the cleaning water discharged from the cleaning nozzle. However, it is not preferable that the structure becomes complicated or the operation becomes complicated.

Therefore, for example, it is not necessary to transfer the washing water from the measuring rack 292 to a measuring cylinder or the like to measure the washing water, and the working labor can be further reduced.

Therefore, the measuring rack 292 is mounted in place of the crossover rack 218 having the extra-liquid transfer section, and the amount of the washing water stored in the measuring rack 292 is measured by reading the scale 324. Thus, the amount of the cleaning water discharged from the cleaning nozzles 262, 264, and 266 can be accurately and easily grasped.

As described above, if the amount of the measured washing water is grasped, the concentration control of the treatment liquid becomes thorough. In addition, even when there are a plurality of processing tanks, it is convenient if one weighing rack 292 is used in common for each processing tank, because only one is required.

Further, the storage sections 312 and 314 are provided with at least the large diameter sections 312A and 314A and the large diameter sections 312A and 314A.
A, 312A, 314 with a smaller cross section than A, 314A
A and small diameter portions 312B and 314B formed continuously, and the scale 324 is provided at a portion corresponding to the small diameter portion 312B. In addition, the change is enlarged and the amount of the washing water can be read more accurately.

When the washing water stored in the weighing rack 292 is discharged from the weighing rack 292, the weighing rack 29 is disposed such that the pair of outlets 316 and 318 are on the lower side.
If 2 is inclined, it is possible to discharge easily.

On the other hand, to mount the cleaning nozzle unit 254, the cleaning nozzles 262, 264, 266 are connected to the through holes 268, 2
70, and the locking piece 272 is
Is elastically locked with the locking hole 275. As a result, the case 256 is attached to the side wall 224 of the crossover rack 218. In the mounted state, the cleaning nozzles 262, 2
By discharging the cleaning water from the liquids 64, 266, the rollers 226, 22 located outside the liquid, ie, outside the liquid,
8, 300, 302, guides 242, 244, etc. can be cleaned.

The maintenance and inspection of the cleaning nozzles 262, 264 and 266, the crossover rack 218 and the processing rack 58
In order to remove the cleaning nozzle unit 254 for maintenance and inspection, etc., the locking piece 272 is disengaged from the locking hole 275, and the cleaning nozzles 262, 264, 266 are released from the through holes 268, 270 in the side wall 224. I just need.

As a result, the crossover rack 21
8 can be easily attached and detached, and in the mounted state, the cleaning nozzles 262, 264, and 266
And the positions of the cleaning nozzles 262, 264, and 266 are held at predetermined positions suitable for the extra-liquid transport unit. In order to remove the cleaning nozzle unit 254, it is necessary to further disconnect the connection between the L-shaped tube 260 and the upstream pipe 282.

Since the pair of storage portions 312 and 314 are connected to each other by the communication portion 322, the scale 324 is provided only in one of the storage portions 312 and 314. 314 may be provided respectively. Further, the weighing rack 292 is formed of, for example, a transparent synthetic resin such as ABS, but is not limited thereto. For example, the scale portion may be formed of transparent glass or the like.

The present invention is not limited to the above embodiment. For example, in the above-described embodiment, the processor unit of the printer processor has been described. However, the processor unit is not limited to such a unit. For example, the processor unit may be provided independently. The photosensitive material is not limited to photographic paper, but may be a negative film or the like.

[0081]

As described above, in the measuring rack for the photosensitive material processing apparatus of the present invention, the amount of cleaning water discharged from the cleaning nozzle can be easily and accurately grasped.
