DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a photographic light-sensitive material supply apparatus for cutting a photographic light-sensitive material into a predetermined length and conveying the cut photographic light-sensitive material to an exposure unit.

[0002]

2. Description of the Related Art As a photographic printing apparatus for printing a negative image of a negative film (hereinafter, referred to as a film) on a photographic photosensitive material (hereinafter, referred to as paper), a paper fed from a paper roll is cut into a predetermined length. 2. Description of the Related Art Conventionally, cut paper is formed, and the cut paper is conveyed to an exposure unit and printed.

Here, the paper roll is usually stored in a paper magazine, and is fed out of the paper magazine.

[0004] When the print size is changed when printing on paper with the above-described photo printing apparatus, it is necessary to supply cut paper having a width corresponding to the print size to the exposure unit.

[0005] By the way, when switching papers in accordance with a change in print size, several types of roll paper having different width dimensions are individually stored in a paper magazine,
If the paper magazine is replaced in accordance with the change of the print size, the printing process corresponding to the print size can be performed. However, the print sizes include E size, L size, 2E size, 2L size, There are many sizes such as European service size, panorama size, high-vision size, 8-cut size, 6-cut size, 4-cut size, etc., and whenever the print size is changed from such various types of paper, select the necessary paper Therefore, there is a problem that the printing process cannot be performed efficiently because the paper magazine needs to be replaced.

Further, the frame size of one frame of the film is divided into a half size and a full size, and different printing methods are used in printing. this is,
In the half size, since the full size frame is used by dividing it into 使用, the negative image becomes vertically long, and when printing is performed in the same manner as in the full size at the time of printing, the image protrudes from the paper. For this reason, what is called “horizontal baking” is performed in which the film is rotated by 90 degrees with respect to a paper roll for baking. On the other hand, a method of baking a film in parallel with a paper roll is referred to as “vertical baking”.

However, since such a half-size film is subjected to a baking process while being mixed with a full-size film at the time of baking, an operator changes the transport direction of the film every time the film size differs. Therefore, there is a problem that the printing process cannot be performed efficiently.

That is, 1. With the diversification of print sizes, a very large width of paper is required, the time required for changing paper is increased, and the processing efficiency of the machine is reduced.

[0009] 2. The selection of the paper magazine by the operator becomes complicated, and the work efficiency is reduced.

[0010] 3. Workers were required and automation was difficult.

[Effect] In the first invention configured as described above,
A plurality of paper magazines containing paper rolls with different widths are provided, and cut paper is supplied from the magazine to the paper transport device by a paper transfer device, so that multiple print sizes with different paper magazines can be changed without replacing the paper magazine. Cut paper can be efficiently supplied to the paper transport device. For this reason, print printing processing can be performed extremely efficiently, and various kinds of printing can be easily performed in a short time.

In the second invention, the paper delivery device includes a paper rotating device that rotates the cut paper received from the cutting device and changes the direction of the cut paper.
The direction of cut paper supplied to the paper transport device can be freely changed by the paper rotating device, so one cut paper can be printed in different printing methods such as "vertical printing", "horizontal printing", "full size", "half size" Since it can correspond to different negative dimensions and different print sizes such as "E size" and "2E size",
The type of roll paper prepared for the baking process can be reduced. For this reason, the processing efficiency of the machine can be improved. Further, the size of the device can be reduced.

In the third invention in which the paper delivery device supports the paper rotating device on the arm, even if the paper magazine increases, if the paper magazine is arranged around the paper delivery device, it is possible to transfer the cut paper. Can be performed with a single arm, thereby suppressing an increase in cost.

In the fourth aspect of the present invention, in which the paper magazine feeding device, the cutting device, and the paper delivery device are provided with a control device for supplying cut paper to the supply end of the paper conveyance device, the negative screen detection means and the width are provided. By providing the detecting means and the film transport direction detecting device, the screen size and the printing direction can be detected simply by inputting the print size, and the cut paper can be automatically supplied to the paper transport device. Can be automated. In addition, it is possible for the operator to perform another operation, and the cost can be reduced.
