Abstract

PURPOSE:To easily assemble a blade and an upper reversal guide into a processing tank and to reduce the cost of a processor by arranging the upper reversal guide obtained by integrally forming a guiding part and a blade part between a 1st processing tank and a 2nd processing tank. CONSTITUTION:After a photographic paper 28 which is elevated and conveyed in a bleaching tank 24 passes an end part 52B, it is conveyed to above a washing tank 26 while it is guided by the circular arc-shaped guiding part 52. Then, the paper 28 is inserted between a roller 38 having a large diameter and a roller 40 having a small diameter on one side while it is guided to the end part 52A. Bleaching liquid is removed by a blade 54. Since the upper reversal guide 44 which conveys the photograpahic paper 28 to the washing tank 26 from the bleach tank 24 is integrally formed, the number of parts is reduced. Then, the blade 54 and the upper reversal guide 44 are easily assembled to the upper part of the processing tank because the blade 54 is attached to the upper reversal guide 44.

It is transported through the tank and subjected to various treatments.

An upper reversing guide for guiding the photosensitive material into an adjacent processing tank is disposed above each processing tank. The upper reversing guide includes a first guide that horizontally guides the photosensitive material sent upward from the first processing tank;
and a second guide that guides the photosensitive material horizontally guided by the first guide downward.

On the other hand, the first processing liquid adhering to the photosensitive material is taken out from the first processing tank and is deposited on a roller on the exit side of the photosensitive material in the first processing tank. For this reason, conventionally, a blade is provided on the exit side roller, and as the roller rotates, the blade removes the first processing liquid adhering to the roller.

[Problems to be Solved by the Invention] However, in the conventional photographic processing apparatus described above, the upper reversing guide is arranged in the first guide disposed above the first processing tank and in the upper part of the second processing tank. Since the guide is divided into a second guide and a second guide, there are problems in that the number of parts is large and the cost is high.

In addition, since the upper reversing guide is divided into two parts, the transport roller located at the exit of the photosensitive material in the first processing tank and the first
It is necessary to adjust the positions of the first guide and the second guide, and it is very troublesome to assemble the upper reversing guide, resulting in poor assembly performance.

Furthermore, since a blade is placed on the exit side of the photosensitive material in order to remove the processing liquid attached to the roller placed on the exit side, the upper reversing guide is placed above the first processing tank and the second processing tank. It was troublesome to assemble while positioning.

SUMMARY OF THE INVENTION In view of the above circumstances, it is an object of the present invention to provide a photographic processing apparatus having an upper reversing guide that can be easily assembled into a processing tank and reduce costs.

[Means for Solving the Problems] In order to achieve the above object, in the present invention, the photosensitive material fed upward from the pair of conveying rollers in the first processing tank is turned downward and subjected to the second processing.

It is characterized in that an upper reversing guide is disposed between the first processing tank and the second processing tank.

[Function] According to the present invention having the above configuration, the upper reversing guide is placed between the first processing tank and the second processing tank, and the upper reversing guide is connected to the upper part of the first and second processing tanks. Assemble. At this time, since the upper reversing guide is integrally fixed, there is no need to adjust the position of the upper reversing guide on the first and second processing tanks, and the upper reversing guide can be easily assembled to the transport rack. I can do it.

Further, the blade portion of the upper reversing guide comes into contact with a conveying roller disposed at the outlet of the photosensitive material in the first processing tank. As a result, the processing liquid carried out by the photosensitive material in the first processing tank and adhered to the conveyance roller is removed.

The upper reversing guide, which is disposed above the first processing tank and the second processing tank, directs the photosensitive material sent upward from the first processing tank downward by the guide part. It is inverted and guided into the second processing tank.
