DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technique for printing a photographic film on a photographic paper by printing and then developing the photographic paper to produce a print.

[0002]

2. Description of the Related Art The technology of printing from photographic film to photographic paper and developing it has been used for a long time, and it can be said that almost all technologies for black-and-white type have been used from the era of manual work to the fully automatic one.

[0003] However, with the rapid increase in use with the spread of color photography, a certain size (service size,
(L size etc.), high-speed processing has been performed. As so-called simultaneous printing, development has been carried out to promptly provide prints to customers.
On the other hand, the use of photographs has become more frequent, and the demand for large-size enlargement prints, which until now has been said to be used only by professional photographers, has increased. This can be said that large-size enlargement has become available to general users, supported by improvements in the sensitivity of photographic film, finer particles, and improvements in the shooting capability of cameras. In order to meet such demands, both printing apparatuses and automatic developing machines having a large width paper passage capable of processing large-size photographic paper have been prepared.

[0004] In order to arrange the lab and the operation efficiency of the apparatus, an automatic developing machine for photographic paper having a large width paper passage is provided.
It is necessary to avoid placing the printer separately from the conventional automatic processing machine with a narrow paper path such as the service size. To be processed. However, it is not efficient to process small-size photographic paper through a large-sized automatic developing machine normally one sheet at a time (in a single row), which is inefficient. In addition, small-size photographic papers that have been separately printed and exposed were brought together and manually inserted in a sufficient number of sheets to fit in the width of a paper passage of an automatic developing machine. Such manual work does not necessarily improve the overall efficiency just because it can be done.

[0005]

SUMMARY OF THE INVENTION The present invention eliminates the inconvenience of the prior art described above and provides a photographic sorting apparatus for feeding small-size photographic paper in a plurality of rows to a large-size automatic photographic paper developing machine. The purpose is to do

[0006]

According to the present invention, there is provided a photo-distributing apparatus for achieving the above object, which is light-tightly connected to a printing paper discharge section of a printing apparatus, and receives a printing sheet in the form of a cut-sheet which has been printed and exposed. A photo sorting device that sorts a plurality of rows in the traveling direction and simultaneously or sequentially sends the sorted photographic papers to an automatic developing machine connected or arranged in the downstream, wherein the sorting is determined according to the print size, It has a control means for determining the number of sorting columns.

Further, the photo sorting apparatus of the present invention is connected to a printing paper discharge section of a printing apparatus, receives a printing sheet in the form of a cut sheet that has been printed and exposed, sorts the printing sheet into a plurality of rows in the traveling direction, and sorts the sheets. A photographic paper sorting apparatus for simultaneously or sequentially sending photographic paper to an automatic developing machine connected or arranged in the downstream, wherein the determination of the sorting is performed by determining the number of sorting rows according to a print size or the number of sorting rows. A control means is provided for performing positioning so as to change the transport line sequentially over the entire area of the photographic paper transport roller of the automatic developing machine by sorting by the following number of rows.

[0008]

In the present invention, the photo distributing apparatus is light-tightly connected to the photographic paper discharge section of the printing apparatus because the printing apparatus is used in a light room and is printed and exposed on a cut sheet of photographic paper. It is distributed immediately and processed by an automatic processor to prevent the latent image from degenerating and to reduce the work in the dark room. Only from baking to completion of the developing process can be performed. However, this does not necessarily mean that the connection with the automatic developing machine is made light-tight. Reason,
When an automatic developing machine for a large size that has already been used is placed in a dark room, and it is useful for various purposes and the distribution device of the present invention is to be used, the automatic developing machine is left installed in the dark room, By providing the discharge opening of the sorting device connected to the printing device installed in the light room through the light shielding wall of the dark room, the sorted photographic paper can be inserted into the automatic developing machine in the dark room. It is. In the present invention, the determination of the sorting is made such that the number of sorting rows is determined according to the print size, because the processable width of the automatic developing machine is determined, so that the width of the adopted print size in the sheet passing direction is sorted and simultaneously determined. When passing through an automatic processor,
This is because it becomes a reference for calculating the number of sheets to be arranged so as not to overlap with the adjacent photographic paper.

The print size is for performing printing exposure to maximize the width of the photographic paper loaded in the printing apparatus, and one side of the print size is determined by the width of the photographic paper, and the other side is determined. The side is determined by the length of cutting the photographic paper. Therefore, in the present invention, since the width of the photographic paper loaded in the printing apparatus contributes to the calculation for sorting, the width of the photographic paper loaded in the printing apparatus is sent to the control means as information, and the sorting row is sent. The number may be calculated and determined, or the width of the photographic paper may be input by a separate input means and sent to the control means to calculate and determine the number of sorting rows.

[0010] Next, "distribution by the number of columns within the number of distribution columns calculated by the control means" means that the entire processable width of the automatic developing machine is not used. By sorting as it exists, it is possible to sort to the outermost end of the processable width of the automatic developing machine irrespective of the print size. Therefore, the sequential transport line according to claim 2 of the present invention. By changing the transport line from the outermost end of the processable width of the automatic developing machine to the other uppermost end in order, and continuing the developing process, a specific part in the automatic developing machine can be changed. Alternatively, it is intended to prevent stains and the like from adhering and accumulating on a specific transport line, thereby preventing image stains from being generated early in printing.

BRIEF DESCRIPTION OF THE DRAWINGS FIG.

FIG. 1 is an overall configuration diagram of an embodiment of a photographic processing system provided with a photographic distribution device according to the present invention.

In FIG. 1, a printing apparatus 1, a sorting means 2, an automatic developing machine 3, and an accumulating means 4 are connected so that a series of processes are continuously performed.

First, in the printing apparatus 1, an image of the negative film 9 loaded on the negative carrier is conveyed to the exposure table 7 by the projection lens 8 and transferred to the exposure stand 7 by the light illuminated by the light source 10. An image is formed on paper P and printing exposure is performed. Prior to the printing exposure, the photographic paper P was stored in the original magazine 5 as a long roll.
After being sent out by the sending-out means 23 and cut by a cutter 6 according to a desired print size by a measuring means (not shown), it is transferred to the conveying means 24 in the exposure table 7 and conveyed, and reaches the central exposure position and stops. Then, after the desired printing exposure is completed, the sheet is transferred to the next intermediate transfer unit 25 by the transfer by the transfer unit 24 again, transferred to the upper right, and transferred to the entrance roller pair 26 of the next sorting unit 2. . The transfer speed of the inlet roller pair 26 is determined by the printing device 1
And the transfer speed of the intermediate transfer means 25 may be high.

Next, the printing paper P conveyed by the pair of entrance rollers 26
Enters the sorting unit 11, engages with the guide 22, stops the conveyance, and moves the guide 22 in the direction perpendicular to the plane of FIG.
The engaged printing paper P is shifted to one side of the transport path. In this embodiment, an example is shown in which two rows are allocated. However, the present invention is not limited to two rows, and a plurality of rows can be easily implemented by appropriately setting the above-mentioned offset stroke. In this embodiment, there are two rows, and the printing paper P
When the conveyance is restarted after the sheet 1 is shifted to the rear side, the photographic paper P1 is delivered to the next roller pair 12, and is conveyed by being driven downward by the roller pair 12. Then, the next pair of rollers 13 and 14 are set so that the nip pressure is set to be low and the photographic paper P1 is driven to rotate by pushing the photographic paper P1.
It is pushed between the rollers 14 and stops moving when it leaves the pinch of the roller pair 12.

In this embodiment, since there are two rows, the roller pair
13 and 14 are divided into two rows in the direction perpendicular to the plane of FIG. 1 and each roller pair is a shaft-supporting type that is not connected to a shaft. Therefore, the length of the roller pair is determined for each of the two rows. When a small-size photographic paper is pushed in, the roller pairs in the row concerned are driven to rotate, and the roller pairs in other rows are not rotated.

Next, the photographic paper P2 which has entered the sorting section 11 is engaged with the guide 22 which has returned to the center after the above-mentioned shifting, is shifted toward the front, and when the conveyance is resumed, the printing is resumed. The paper P2 is delivered to the next pair of rollers 12, and is conveyed by being driven downward by the pair of rollers 12. At this time, since the photographic paper P2 is pushed along the row before the next pair of rollers 13 and 14, the back side of the pair of rollers 13 and 14 holding the already pushed first photographic paper P1 is pressed. Since the shaft is not connected to the row, the photographic paper P1 on the far side does not move by the pressing of the photographic paper P2 in the front row this time.
Then, the photographic paper P2 in the front row also stops moving when it leaves the nipping of the roller pair 12.

The photographic papers P1, P2 arranged in two rows in this manner
Since P2 is performed within one order, since it is of the same size, the movement is stopped when the pair of rollers 12 is left apart, so that not only the rear end positions are aligned, but also the front end in the traveling direction is aligned. .

Next, in this embodiment, since two rows are set, when the two rows have been allocated as described above, the roller pair 1
Conveyance of 3 and 14 is started, and the two rows are simultaneously conveyed upward through the roller pair 15 and transferred to the automatic developing machine 3.

The photographic paper which has been subjected to the development processing by the automatic developing machine 3 is discharged to the tray 16 by discharge rollers 27. Tray 16
A push rod 17 attached to an extruding means comprising a mechanism (not shown) built in the printer waits for the photographic paper P to be discharged to the tray 16 and moves vertically to the plane of FIG. And the photographic paper P2 is dropped and stacked on the stacking section in front.

In this example, since there are two rows, the photographic paper P2 on the front side falls first into the stacking section, and then the photographic paper P1 on the back side falls and is stacked. By repeating one after another, photographic paper for one order is stacked on the stacking unit, and the order is also adjusted.

As described above, in the sorting means 2, in this embodiment, the roller pair is divided into two rows as means for pushing the sorted photographic paper into the transport section in a plurality of rows.
The number of divisions may be increased by a desired number of rows, or the pair of rollers 13 and 14 may be released without being divided and locked so that the driven rotation is not performed. It is also possible to adopt a method in which the paper can be pushed in, the rollers 13 and 14 are pressed against each other when the pushing is completed, and the photographic paper is nipped and the conveyance is started. In order to simultaneously rotate the rollers divided into a plurality of rows at the time of resuming the conveyance, each of the roller pairs 13 and 14 has one shaft, and the rotating drive roller is in contact with the outer periphery thereof.

Next, regarding a plurality of determinations, the photographic paper processable width of the connected automatic developing machine is wide in accordance with large-size printing, and this width is input to the arithmetic and control means as a specified size. The print size is determined according to the order in accordance with the photographic paper width of the magazine loaded in the printing apparatus, and is input to the arithmetic control means to calculate the number of rows.
The processing may be performed with the number of columns according to the arithmetic control without particular designation, or the processing may be performed with the number of columns selected within the number of columns by the arithmetic operation by a separately provided selecting unit. This is because it is advantageous for the stability of the processing to complete the processing for one order with as many rows as possible in consideration of the number of prints for one order. The term "stable processing" as used herein means particularly stable development processing.After the processing is continuously performed to the full width of the photographic paper, the photographic paper abuts when the photographic paper is suddenly shifted by one line. This is because the processing liquid stain often adheres to the portions that have not been removed, and the stain may adhere to the photographic paper to be passed next, causing image stains. Therefore, it is preferable to complete the assignment for each order as evenly as possible, and in consideration of the necessity of another assignment for the next order, the assignment can be completed or reset for each order.

FIG. 2 is a schematic diagram showing a state in which the photographic paper sorted by the photo sorting device is conveyed in the automatic developing machine 3.

Referring to FIG. 2, a description will be given of an embodiment in which the transfer lines are sequentially changed over the entire area of the photographic paper transfer rollers of the automatic developing machine by sorting by the number of rows within the number of sorting rows. In FIG. 2, W is the processable width (maximum width) of the automatic developing machine.

As shown in FIG. 2, first, the sorting was performed in two rows, and the two rows were sequentially sorted from the back side. If the continuous operation is continued in this state, the dirt adhesion indicated by the hatched portion D progresses, so that the transport line is sequentially changed in the forward direction, and that the dirt and the like adheres and accumulates on a specific portion or a specific transport line. To prevent.

In order to explain the outline of the operation of the automatic developing machine 3 shown in FIG. 2, the sorting device provided upstream of the automatic developing machine 3 first allocates the image to the innermost row and the second row adjacent thereto. The photographic paper P is transferred to a roller conveying means of a developing tank 30 which is a first processing tank of the automatic developing machine 3, developed, and then successively passed through a bleach-fixing tank 40, a washing or stabilizing processing tank 50, and dried. The paper is dried in the section 60, discharged as a print on the tray 16, and pushed forward by the push rod 17 of the extruding means which has been waiting, and is accumulated.

It is preferable from the viewpoint of the system configuration to sequentially change the transport line for each order, but the present invention is not limited to this.

[0029]

As described above, the photographic sorting apparatus of the present invention is constructed as described above, so that the multi-row processing is performed according to the print size and the automatic developing machine is effectively used, so that the processing capacity is improved. , And a stable processing ability can be maintained since the adhesion of dirt is not concentrated.
