2. Description of the Related Art In general, a photographic processing apparatus comprises an image forming apparatus, a printing processing chamber having an exposure unit for printing an image on photographic paper, and processing tanks such as a developing processing tank, a bleaching processing tank, and a fixing / stabilizing processing tank. And a development processing chamber provided with

Further, a paper magazine in which roll-shaped photographic paper is stored and a plurality of transport rollers for pulling out the photographic paper from the paper magazine and transporting the paper are arranged in the printing chamber.

[0004] The photographic paper drawn from the paper magazine is cut into a predetermined size before being sent to the exposure unit, and the cut photographic paper is sent to an exposure table of the exposure unit by a transport roller. And print the image on photographic paper.

When performing so-called solid printing, in which the entire processed image of the film is printed on photographic paper while maintaining the size of the film, the film to be solid-coated is fixed in a film holder. Open the door of the fuselage, set the film holder on which the film was set between the exposure table and the light source in the exposure unit, in the holder unit arranged close to the exposure table, and closed the door. The baking process is performed.

[0006] However, in the pasty printing, an image of the entire film is usually printed on a piece of photographic paper cut to a predetermined size while maintaining the size of the film.
In the case of performing the solid baking by changing the film, it is necessary to perform an operation of replacing the film each time one solid baking process is completed.

[0007] This film replacement operation is performed by opening the opening / closing door of the machine, so that not only photographic paper on which an image has been printed but also unprinted photographic paper remains inside the machine. It is necessary to prevent this.

Accordingly, the photographic paper subjected to the printing process is transported to, for example, a development processing room which is shielded from external light, and the uncut photographic paper pulled out from the paper magazine is removed. , Because it is pulled out to the entrance of the exposure table of the exposure unit, when the solid printing is completed, if the uncut photographic paper is not rewound to the paper magazine, if the opening and closing door is opened,
The photographic paper is exposed to external light, causing fogging of the photographic paper.

[0009]

However, when performing solid printing, every time the exposure processing is completed, the exposed photographic paper is sent to the development processing chamber, and the unprocessed photographic paper is transferred to a paper magazine. Since it is necessary to open the opening / closing door after rewinding, it is necessary to consciously carry out these transporting and rewinding operations every time, and the workability is poor.

In addition, there is a case where the operator forgets to carry out and rewinds the printing paper, in particular, rewinds the printing paper, opens the opening / closing door, and covers the printing paper, and still wastes paper. Had occurred.

Furthermore, if the opening / closing door is opened without rewinding the photographic paper into the paper magazine, the uncut photographic paper is located at the entrance of the exposure table, and the film on which the film is set is located. When the fixing mask is pulled out, the photographic paper may be damaged, and the paper may be jammed.
