In addition, a large number of guide plates are bridged between the stays arranged above and below, and these guide plates constitute a guide for converting the leading end of the photosensitive material into the conveying direction. That is, in the processing rack, a large number of guide plates and rollers are arranged between the side plates to form a conveyance path for the photosensitive material, which increases the number of assembly steps, but the size of the guide according to the width of the photosensitive material that can be used. The degree of freedom is high because it is only necessary to replace some of the parts when setting the shape and shape or changing the length of the transport path.

With the increasing use of resin molding, there has been proposed a processing rack in which a side plate, a stay and a guide are integrally molded and rollers are assembled. In this processing rack, the guides for the photosensitive material are integrally molded, so it is only necessary to assemble the rollers and place them in the processing tank, which greatly simplifies the process of assembling the processing tank of the photosensitive material processing apparatus. ing.

And the bearing inserted into the second through hole of the guide frame holds the peripheral portions of the through holes of the side plate and the guide frame between the protruding portion and the flange portion to fix them. And

[0009]

The processing rack according to the first aspect of the present invention is constructed so that the pair of side plates are maintained in the facing state by the guide frame. Rollers that apply a conveying force to the photosensitive material are stretched between the side plates. The guide frame is formed with guides for guiding the photosensitive material conveyed by the rollers in a predetermined direction, and the rollers and the guides form a conveying path for the photosensitive material between the pair of side plates.

The processing rack is configured to determine and fix the relative position between the side plate and the guide frame by means of a bearing that supports at least a part of the rollers. Assemble the side plate and the guide frame at the position determined by the bearing. That is, the bearing is used to fix the side plate and the guide frame.

This processing rack has a structure in which a guide frame forms a stay forming a rack and a guide for guiding the photosensitive material in a predetermined direction, and the side plate and the guide frame are individually molded of resin, It has a configuration in which these are assembled. Therefore, it is possible to reduce the number of parts for constructing the rack and the number of assembling steps. Further, each of the side plate and the guide frame can be individually molded, and the molding process is extremely easy.

A processing rack according to claim 2 of the present invention comprises:
The bearings define the structural means for fixing the guide frame and the side plates. A bearing for rotatably supporting the roller connects the side plate and the guide frame with their relative positions determined.

The side plate and the protruding portion of the guide frame are sandwiched by the flange of the bearing and the protruding portion so as not to separate from each other. If the protrusion of the bearing is inserted into the notch provided in the first and second through holes, and the bearing is rotated in this state to displace the protrusion with respect to the notch, the bearing will have the first and second through holes. The guide frame does not come off from the side plate, so that the guide frame does not come off from the side plate.

As described above, the processing rack of the present invention is composed of the side plate and the guide frame, and these are connected by the bearing to be assembled. Therefore, it is easy to assemble the processing rack. Further, by changing the shape of the side plate or the guide frame, the size and shape of the entire processing rack can be changed, and at least a part of the processing rack can be shared with other size processing racks. For example, processing racks having different film widths that can be used can be assembled by combining guide frames having different guide widths with the same side plate.

Incidentally, the protrusion of the bearing may be in a state of protruding from the outer peripheral portion of the bearing due to an urging force or the like. In this case, the protrusion may be housed against the biasing force and the bearing may be inserted into the through holes of the side plate and the guide frame.
