Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a photographic printing processing apparatus, and more specifically, the present invention relates to a photographic printing processing apparatus, and more specifically, a printing section prints a photographic image from a negative film or the like onto a strip of photographic paper, and the photographic paper is delivered in the strip-like form to a developing processing section. The present invention relates to a photographic printing processing apparatus.

In a photographic printing processing device, in order to directly perform the intermittent printing of prints on strip-shaped photographic paper and the continuous development processing (hereinafter simply referred to as "processing"), the speed of both is increased. 1ii4 Various efforts have been made to mix the sum. Then, they can be divided into 1 types: strips of photographic paper that have been printed are cut into sheets (cut into sheets, each frame by frame).
There are two types of methods: a method in which the edges are delivered to the processing section, and a method in which the strips are delivered to the processing section on a band-shaped support without cutting each image frame.

The former sheet-forming method has problems in terms of harmonizing the speed of print printing and processing, but it also has problems with machines that require a large number of rollers in the processing section to convey the photographic paper cut into small pieces. The drawback is that the drawing is sloppy and the equipment is expensive.

On the other hand, in the latter method, which processes the photographic paper as it is in the form of a strip, the leading edge of the photographic paper is used as a leader, and the paper is conveyed through a chain using a photographic paper guide clip (hereinafter simply referred to as a "clip").
It has the advantage that the mechanism is simple because it is conveyed by engaging with a leading member such as the paper, but in order to balance the speed of print printing and processing, it is necessary to separate the strip of photographic paper from the unprinted part. In some cases. In order to cope with such a case, this ILF photographic printing processing apparatus has a means for cutting the strip of photographic paper, and at the same time, attaches the above-mentioned first insult g1 (material) to the tip "W" of the cut strip of photographic paper. It is desirable to have a means for matching.
