Description

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 feeding apparatus capable of feeding a plurality of sizes of printing paper used for printing in an exposure section from a single paper roll.

[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 film) on a photographic light-sensitive material (hereinafter referred to as paper), the paper fed from a paper roll is cut into a predetermined length. It is known that a cut paper is formed, and the cut paper is conveyed to an exposure unit for baking.

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

When the print size is changed when the paper is printed by the above-mentioned photo printing device, it is necessary to supply the cut paper having the width corresponding to the print size to the exposure section.

By the way, at the time of switching the paper according to the change of the print size, several kinds of roll papers having different width dimensions are individually stored in the paper magazine,
By changing the paper magazine according to the change of the print size, it is possible to perform the printing process corresponding to the print size. 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-definition size, 8-cut size, 6-cut size, 4-cut size, etc., and each time you change the print size, you can select the required paper from various types of paper. Since it is necessary to replace the paper magazine with a new one, there arises a problem that the baking process cannot be performed efficiently.

The frame size of one frame of the film is divided into half size and full size, and different printing methods are used for printing. this is,
In half-size, a full-size frame is divided into halves for use, so the negative image becomes vertically long, and when printing is performed in the same manner as full-size printing, the image protrudes from the paper. Therefore, so-called "lateral baking" is performed in which the film is rotated by 90 degrees with respect to the paper roll for baking. On the other hand, the method of baking the film in parallel with the paper roll is called "vertical baking".

However, since such a half-size film is printed by being mixed with a full-size film at the time of printing, the transport direction of the film must be changed every time the frame size is different. There is also a problem that the baking process cannot be performed efficiently.

That is, as the printing size is diversified, a paper roll having a very large width is required, the replacement time of the paper magazine increases, and the processing efficiency decreases. Also, the operator's paper magazine selection work becomes complicated,
Work efficiency is also poor.

Further, since a plurality of paper rolls are used, the sensitivity characteristics of the papers are different, which causes a problem that color correction at the time of printing becomes complicated. Moreover, in that case, there is a problem that the paper roll which is rarely used changes with age.

Therefore, an object of the present invention is to supply printing paper of various sizes to the exposure section without preparing a plurality of paper rolls having different width dimensions.

[0011]

In order to solve the above problems, in the first invention, between a paper magazine containing a paper roll to be baked and a paper carrying / feeding device for carrying cut paper to an exposure unit. In addition, the processing means is provided with processing means for processing the paper fed from the paper magazine into cut paper of a required size and supplying the cut paper to the paper conveying device.

At this time, in the second aspect of the invention, the processing means causes the paper feeding device for feeding the paper from the paper roll in the paper magazine and the paper fed by the paper feeding device to have a predetermined length. The cutting device for cutting and the paper rotating means for rotating the cut paper, changing its direction, and supplying it to the paper transporting device, are configured.

In the third aspect of the invention, the cut paper, which is moved between the cutting device and the paper rotating device in a direction perpendicular to the transfer direction of the cut paper and is discharged from the cutting device, is transferred to the paper rotating device. The paper moving / supplying device is provided, and the cut paper receiving portion of the paper moving / supplying device is provided with a slitter for cutting the cut paper into a predetermined width.

Further, in the fourth aspect of the invention, the paper moving / supplying device is provided with a discharge roller for individually discharging the cut paper cut by the slitter to the paper rotating device.

On the other hand, the fifth aspect of the invention employs a construction in which a cutting device for cutting the cut paper into a required length is provided between the paper rotating device and the paper transporting device in the second invention.

On the other hand, in the sixth invention, a transfer means for transferring the cut paper between the feeding device and the paper rotating device in the second invention so as to move back and forth, and the cut paper transferred between the feeding device and the cutting device. That is, the paper holding means for temporarily holding the paper is adopted.

The configuration is provided with the detection means and the control device that creates the cut paper corresponding to the print size from the detection signals of the detection means by controlling the processing means.

[0018]

In the first aspect of the invention configured as described above, the processing means appropriately feeds the paper from the paper magazine, and appropriately cuts the fed paper so that various sizes used in the exposure unit can be obtained. In order to produce the above-mentioned print paper, it is possible to supply print papers of various sizes to the exposure section without preparing a plurality of paper rolls having different width dimensions.

[0019] For example, the dimensions of the print paper, the _{^{E-size, 3 1/4 × 4 3}} /4 inches, at _{^{2E-format, 4 3/4 × 6 1}} /
₂ inches Moreover, in the L-size, 3 _^1/2 × 5 inches, the 2L size, has a 5 × 7 inches, similar to the paper size, vertical and horizontal ratio of 1: As a √2 It is standardized.

For this reason, if 2E or 2L size print paper is cut in half and rotated vertically and horizontally by 90 degrees, E size and L
A print sheet of a standard size is obtained.

[0021] In addition, high-definition size and panorama size, _{^{respectively, 3 1/2 × 6 1}} /4 inch, 3 _^1/2 × 10
The width is the same as the inch.

Therefore, these sheets can be obtained only by changing the feeding size from the same roll.

From these things, in the second invention, the processing means is composed of a paper feeding device capable of feeding the paper for a required length, a cutting device for cutting the paper, and a paper rotating device for rotating the cut paper. This made it possible to create multiple sizes of print paper from paper rolls.

In this case, in the third aspect of the invention, the paper moving and feeding device moves at right angles to the transport direction of the cut paper, receives the cut paper from the cutting device, and cuts the cut paper into an appropriate width by a slitter. Can be cut. In addition, since the paper moving and feeding device cuts the cut paper to an appropriate width, if it is discharged as it is, the exposure axis and the central axis of the cut paper do not coincide with each other during exposure, and printing cannot be performed. In addition, the shaft can be positioned so that the cut paper, which is moved and ejected at a right angle during the ejection, can be exposed in the exposure unit.

As described above, according to the third aspect of the invention, since the cut width can be freely determined, it is possible to widen the selection width of usable paper rolls.

Further, in the fourth invention, each of the cut papers cut by the slitter of the paper moving and supplying device can be discharged to the paper moving and supplying device by the discharging roller, so that the cut paper can be supplied without waste. Moreover, it is possible to stop the supply of unnecessary paper.

On the other hand, in the fifth invention, a cutting device is provided between the paper rotating device and the paper conveying device in the second invention so that the rotated cut paper can be cut, so that the cut paper is transferred in one direction. It can be cut into various sizes.

Further, in the sixth aspect of the invention, since the cut paper is moved back and forth between the feeding device and the paper rotating device by the transferring means, the cutting can be repeated by one cutting device while rotating the cut paper by the paper rotating device. Can cut various sizes. At this time, the paper holding device temporarily holds the cut pieces that are not supplied to the paper transporting device and cuts the cut pieces into a required size so that the cut pieces can be supplied to the paper carrying-out device.

In the seventh invention, the control device determines the size of the print sheet by the negative screen detecting means and the film conveying direction detecting means and supplies it to the paper conveying device.

That is, the negative screen detecting means detects whether the screen size of the film is half size or full size.
In addition, the film transport direction detection means detects the film printing direction, and the control device determines the vertical and horizontal dimensions of the print to be supplied to the paper transport device depending on whether the film is vertically or horizontally burned, and the processing means according to the dimension. Each device can be operated to make cut paper.

That is, in this feeding device, the paper 5 is fed by driving the paper feeding device 7, the traveling roller 52 and the drive roller 39 of the paper rotating device 10.
When the leading edge of the paper 5 is detected by the leading edge detecting device 16 after being inserted through the guide plate 57, the paper 5 is extended by 6 inches and temporarily stopped and cut by the cutting device 8 in order to correspond to the length dimension. Cut paper 1 after cutting
5 is moved to a position where the center of the cut paper 15 and the center of rotation of the paper rotation device 10 coincide with each other by the drive roller 39 of the paper rotation device 10, and the cut paper 15 is moved to 9
Rotate 0 degrees. This rotated cut paper 15
The sheet is conveyed in the reverse direction. At that time, in order to avoid collision with the tip of the paper 5 after cutting, the drive roller 11 of the paper feeding device 7 is reversed, and the rewinding amount is calculated from the rotation speed of the roller 11, The paper 5 is rewound into the magazine until the front end of the paper is ejected from the guide plate 57.

Thereafter, the plunger 32 is operated to lower the guide plate 57 downward, and the drive roller 39 of the paper rotating device 10 and the drive roller 55 of the traveling roller 52 are reversed to reverse the cut paper 15 to the guide plate 57. When the tip is detected by the tip detecting device 16, the reverse feeding is stopped. Therefore, the leading end of the cut paper 15 is held by the traveling roller 52, and the cut paper 15 is once held by the paper guide 53.

The cut paper 15 thus held is again driven by the traveling roller 52 to drive the paper rotating device 1.
The transfer is performed toward 0, and the tip is detected again by the tip detection device 16
When it is detected by, it is stopped at the position 4 inches from the transfer. Then, the cutting device 8 is operated to perform the cutting.
The cut paper 15 that has been cut is transferred to the paper rotating device 10. At this time, in the case of horizontal baking, the paper is transferred to the paper carrying device 2 without being rotated.
In the case of vertical baking, the paper is rotated to 90 ° and transferred to the paper transport device 2. By doing so, the cut paper 15 having a required size can be supplied to the exposure unit 42 regardless of vertical baking and horizontal baking. Paper 1 left
5 can be supplied to the exposure unit 42 by driving the traveling roller 52 and transferring it to the paper transporting device 2 without operating the cutting device 8. At that time, by vertical and horizontal firing,
It suffices to operate the paper rotating device 10.

As described above, in this embodiment, the direction of the cut paper 15 is changed by the paper rotating device 10 and the cut paper 15 is held by the holding means, so that the transfer means can advance and retreat with respect to the cutting device. Thus, the cutting device 8 can perform cutting many times, and the cut paper 15 having a size smaller than the width of the paper 15 can be produced.

In the embodiment, 8 inches (20 cm)
Although the width of the paper is shown, the invention is not limited to this, and, for example, as shown in FIGS.
Paper rolls of other widths such as 10 inches and 12 inches can be freely used according to the print size used in the exposure section.

[Effect] According to the above-mentioned invention, the processing means is provided between the paper magazine and the paper transporting device to process the paper roll fed from the paper magazine into a required size, and various paper rolls can be processed from a single paper roll. Since the paper of the size is prepared and can be supplied to the exposure unit, the following effects can be obtained.

The paper magazine replacement time is eliminated, and the processing efficiency is improved. Since the paper selection work can be automated, the work of selecting the paper magazine for the worker is eliminated and the burden on the worker can be reduced. Therefore, the worker can also perform another work. A single paper type makes color correction easy during printing. The storage of a plurality of papers and paper magazines is not required, and the storage location and maintenance thereof are not required. Since only one paper magazine is required, the device can be made smaller and lighter.
