[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rack cleaning apparatus for a photosensitive material processing apparatus for cleaning rollers and guides provided outside the photosensitive material processing apparatus for immersing a photosensitive material in a processing solution.

[0002]

2. Description of the Related Art A light-sensitive material such as an image-exposed film or printing paper is developed, fixed, washed with water by a light-sensitive material processing device such as an automatic developing device, and then dried to be finished. In such an automatic developing device for processing a photosensitive material, processing solutions such as a developing solution, a fixing solution, and a washing water are stored in processing tanks such as a developing tank, a fixing tank, and a washing tank. A conveyance path for the photosensitive material is formed between the processing tanks inside and between the processing tanks adjacent to each other by rollers, guide plates, and the like.

The photosensitive material inserted into the automatic developing device is successively immersed in a developing solution, a fixing solution and washing water while being conveyed through a conveying path composed of rollers and guide plates, and is subjected to development, fixing and washing treatments. Is done.

By the way, the processing liquid carried out from the upstream processing tank by the photosensitive material as the photosensitive material passes is attached to the rollers arranged between the processing tanks adjacent to each other. The processing liquid adhering to the roller evaporates water during the processing of the photosensitive material for a long time or while the operation of the apparatus is stopped, and the components in the processing liquid are deposited.
The processing liquid component deposited and adhered to the roller damages the surface of the photosensitive material when the next photosensitive material passes, or is brought into the processing tank on the downstream side by the photosensitive material and is transferred to the inside of the processing tank on the downstream side. This will contaminate the processing liquid.

Therefore, some automatic developing devices are provided with a mechanism for cleaning the rollers arranged outside the liquid. A mechanism for cleaning the roller is, for example, provided with a pipe provided with a nozzle for cleaning water on the upper part of the roller, and when the processing of the photosensitive material is interrupted for a predetermined time, the cleaning water is discharged from the nozzle at a predetermined time interval. The treatment liquid adhering to the surface of the roller is washed off by dripping on the surface of the roller. At this time, the roller is rotated so that the peripheral surface of the roller is uniformly washed, and the surface of the guide is also washed by the scattered washing water.

[0006]

However, when an attempt is made to wash the surface of the guide together with the roller with a large amount of washing water, there arises a problem that the washing water enters the treatment tank and dilutes the treatment liquid. It is washed with a little water. Therefore, the cleaning water scattered on the peripheral surface of the roller cannot reliably clean the surface of the guide, and the components in the treatment liquid remaining and deposited on the surface of the guide are
The surface of the photosensitive material to be processed next may be soiled or damaged to impair the quality of the processed photosensitive material.

The present invention has been made in consideration of the above facts, and provides a rack cleaning apparatus for a photosensitive material processing apparatus capable of reliably cleaning the surface of a guide for guiding the photosensitive material together with a roller arranged outside the liquid. The purpose is to do.

According to the second aspect of the present invention, the cleaning control means of the cleaning water supply means switches to some of the cleaning water ejection means for a certain period of time to eject the cleaning water. here,
From the pressure of the cleaning water supplied to the cleaning water ejection means and the time during which the cleaning water is supplied, the amount of the cleaning water ejected can be accurately known.

If this part of the cleaning water jetting means is provided, for example, in a processing tank that stores a processing solution that is difficult to be diluted with the cleaning water, the amount of the cleaning water recovered in the processing tank by cleaning the rack. If the amount of diluting water when replenishing the replenisher is adjusted from the amount of wash water, it is possible to prevent the treatment liquid in the treatment tank from being diluted by the wash water. Can be prevented.

According to the third aspect of the present invention, as the washing water jetting means, for example, a washing nozzle for jetting the washing water while diffusing the washing water is used depending on the shape of the jet outlet at the tip of the nozzle or the shape around the jet outlet. . This cleaning nozzle is arranged on the rack side plate, and the cleaning water is jetted from the rack side plate side toward the roller and the guide surface. This reliably prevents interference with the conveyance path of the photosensitive material when the cleaning water is sprayed over a wide area along the axial direction of the roller or the like .
