[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a photographic processing apparatus for processing a photosensitive material.

[0002]

2. Description of the Related Art As a specific example of the above-described photographic processing apparatus, an example of a photographic printing apparatus according to the prior art for printing and developing a film image on a photographic paper as a photosensitive material will be described with reference to FIG. The photographic printing apparatus 1 shown in FIG. 15 is roughly divided into a printer section P and a development processing section DE. A printer section P for detecting image information of the film, a scanner section SC including a light source 10 and a film transport unit U1 for a scanner section for transporting and positioning the film;
A light source 20 and an exposure unit EX for projecting and exposing the image information of the film onto the photographic paper 3 taken out from the cartridge 4.
Has an exposure section EX provided with an exposure section film transport unit U2 for transporting and positioning the film.
The exposed photographic paper 3 is developed in the developing section DE. The photo printing apparatus 1 further includes a controller (not shown) for controlling the operation of each unit. An operation console (not shown) for inputting various control instructions, a monitor TM for displaying image information read by the scanner unit SC, and the like are connected to the controller.

When a film to be printed is inserted into the scanner section SC, image information of the film is read for each frame by the scanner section SC, and the image information is sent to the controller. The film for which the reading of the image information has been completed by the scanner unit SC is transported to the exposure unit EX.

[0004] The printing paper 3 which has been exposed in the printer unit P forms a loop in the loop unit L, is conveyed to the developing unit DE, is developed, and is cut one by one corresponding to each frame of the film. It is discharged at the discharge section in a state where it has been removed. The development processing unit DE includes a plurality of processing tanks filled with a plurality of processing liquids for developing the exposed photographic paper 3 and a cutter for cutting the photographic paper 3 after the development processing for each frame. Provided.

[0005] The photographic printing apparatus 1 having the above configuration
Then, the transport direction of the photographic paper 3 in the printer unit P,
The photographic printing papers are arranged so that they are adjacent to each other in the same direction in the development processing unit DE. That is, the printer unit P and the development processing unit DE are arranged linearly or in series. What is important in the process of transporting the printing paper 3 is that the surface on which the image of the printing paper 3 is generally printed is called an emulsion surface A (B is the opposite side) immediately before being transported to the development processing unit DE. That is, the sheet is transported downward in the loop portion L located. The photographic paper 3 in the developing section DE is conveyed in this manner.
Is stabilized.

[0006]

In general, the prior art photographic printing apparatus, including the photographic printing apparatus having the above-described configuration, has the following problems. (1) Since the printer section and the development processing section are connected in a straight line, the overall length of the photographic printing apparatus becomes longer.

(2) To solve this problem,
Arrange the transport direction of the film and photographic paper orthogonally,
There is an example in which a configuration is used in which printing is performed so that the width of the film becomes the feed length of the photographic paper. In recent years, however, the frequency of printing 135 films that have been photographed in a mixture of full size and panorama size, and new standard films that have been photographed in a mixture of several formats on a single film, is increasing. To print these, it is more convenient to print in different formats by making the film feeding direction parallel to the photographic paper feeding direction, keeping the photographic paper width constant, and changing the feeding length. However, in this case, the total length of the photographic printing apparatus becomes long to obtain a photographic printing apparatus having the same capacity as the above arrangement.

(3) In a photographic printing apparatus in which the scanner section and the exposure section of the film are arranged at different positions, each operation can be performed at the same time, and the printing efficiency can be improved.
However, in such a machine, the scanner unit and the exposure unit are inevitably arranged in series, and it is inevitable that the total length of the apparatus becomes long by transporting the film and the printing paper in parallel.

(4) If the printer section and the developing section are arranged in series, at least one of the traveling directions of the film may be blocked by the developing section or the like, which may affect operability. (5) In general, in the printer section, the emulsion side of the photographic paper is directed upward and in the development processing section downward, the layout of the equipment components is more efficient and the processing stability is more convenient. Providing a path for reversing the direction of the emulsion side of the paper between the printer section and the development processing section lengthens the transport path, and attempts to reduce the length of the paper so as not to affect the length of the machine. If this is the case, the transport route becomes complicated.

(6) In the prior art, there is a means for changing the optical path of printing using a mirror to reduce the size of the apparatus.
In this case, since the reflected light is used, a larger amount of light is required, and when the mirror is contaminated with dust, the print quality is deteriorated and maintenance is required. (7) Since it is desired to reduce the installation area, the photographic printing apparatus must be designed to be compact. However, in order to satisfy the required functions, the same mechanism as before has to be compactly housed in the small photographic printing apparatus, and the maintainability and the like are reduced.

In view of the above-mentioned problems, while making the transport direction of the film and the transport direction of the photographic paper parallel,
It is necessary to change the optical path for printing using a mirror or the like,
Further, there has been a demand for a photographic printing apparatus having a structure in which the length of the photographic printing apparatus is made as short as possible without having to make each part of the photographic printing apparatus compact. More generally, there is a demand for a photographic processing apparatus which can arrange parts in a state where space is used most effectively, without being limited to the photographic printing apparatus as described above. One of the important points in the above problem is how to change the conveying direction of the conveyed photosensitive material to another direction.

Become.

Furthermore, in a preferred embodiment of the present invention, it is desirable that the direction changing mechanism is configured to reverse the surface of the photosensitive material. With such a configuration, for example, when the photosensitive material is photographic paper, the direction in which the emulsion surface on which an image is printed faces and the direction in which the opposite side faces are switched, so that the photographic paper is At the same time as changing the direction and shortening the length of the photographic printing apparatus, the image printing surface that was upward in the printer section is turned downward before being transported to the development processing section, and the arrangement of the equipment components is made more efficient, It is possible to improve the stability of the processing and the like.

In a preferred embodiment of the present invention, a pneumatic means for attracting the photosensitive material toward the main body by causing a difference in air pressure between the vicinity of the front surface and the back surface of the photosensitive material in the holding portion.
