2. Description of the Related Art A printer processor is called a minilab and is installed in a DPE store or the like. This printer processor has a structure in which a printer unit that prints and exposes an image recorded on a negative film on photographic paper and a processor unit that develops the photographic paper that has been subjected to the print-exposure process are integrated. Therefore, simply by setting a long photographic paper in the printer processor, the photographic paper can be automatically cut, and the cut photographic paper can be conveyed and processed in the printer unit and the processor unit. In the printer section of this printer processor, the image on the negative film is enlarged to a selected fixed size and printed on the photographic paper, and the photographic paper on which the image is printed is sequentially conveyed to the processor section. Developed and finished as a photographic print.

By the way, photographic papers are usually arranged in a line in the processor section and processed while being conveyed. But,
With a printer processor capable of processing narrow to wide photographic paper, when conveying small size photographic papers for printing exposure processing and development processing, if they are conveyed side by side in a line, it will increase the processing capacity of the printer processor. for,
The number of photographic papers that can be processed is small, resulting in low efficiency.

Therefore, when carrying a small size of printing paper, it is necessary to soak the printing paper in each processing tank for a predetermined time for processing in particular. Can be improved.

As an example of the sorting device for arranging in a plurality of rows in this way, one disclosed in Japanese Patent Laid-Open No. 6-332144 is known. This publication describes a method in which the photosensitive material is sequentially shifted and fed in a direction intersecting the transporting direction, the feed speed is adjusted, and the photosensitive material is transported to the processor section in a staggered arrangement.

[0006] And, such a distribution device found in this publication and other publications so far uses a slide rail and a ball screw or a rack and pinion or a crank mechanism as a drive mechanism of the distribution table. , It adopts a structure in which the photosensitive material on the sorting table is sorted while being conveyed.

[0007]

As described above, in the conventional sorting device, not only the plurality of rollers for transporting the photosensitive material are arranged on the sorting table, but also the ball screw and the screw for sliding the sorting table are provided. Since the crank mechanism is arranged, the number of parts is large, a complicated and expensive mechanism is required, and the manufacturing cost is high.

Furthermore, the sorting table, which requires at least a size larger than the area of the photosensitive material to be sorted, must be slidably arranged, which requires a large space in the printer processor. It has a drawback that it is difficult to downsize.

In view of the above facts, an object of the present invention is to provide a low-cost photographic printer sorting apparatus and photographic printer which can sort a photosensitive material into a plurality of rows without requiring a large space.

[0010]

According to a first aspect of the present invention, there is provided a photographic printer sorting device which sorts a plurality of photosensitive materials to be processed while being conveyed into a plurality of rows. And a guide stand disposed opposite to the surface side, capable of moving along the sorting direction while being in contact with the exposed surface side of the photosensitive material, and static friction between the non-exposed surface side of the photosensitive material and the guide table. A distribution member having a coefficient of static friction with the exposed surface side of the photosensitive material that is larger than the coefficient.

According to a second aspect of the present invention, there is provided a sorting device for a photographic printer, which sorts a plurality of photosensitive materials to be processed while being conveyed, into a plurality of rows. The sorting device faces the non-exposed surface side of the photosensitive material. It is possible to move along the distribution direction while being in contact with the disposed ferromagnetic material and the exposed surface side of the photosensitive material, and from the static friction coefficient between the non-exposed surface side of the photosensitive material and the ferromagnetic material, And a plastic magnet formed by mixing a magnet material in a resin material and having a large static friction coefficient with the exposed surface side of the material.

A photographic printer according to a third aspect of the present invention is a photographic printer in which a photosensitive material is sent to a developing processing section in a state where the photosensitive material is distributed in a plurality of rows, and the developing processing is performed. The photographic printer is arranged facing the non-exposed surface side of the photosensitive material. Of the photosensitive material can be moved along the distribution direction while being in contact with the exposed surface side of the photosensitive material, and the exposure of the photosensitive material is determined by the coefficient of static friction between the non-exposed surface side of the photosensitive material and the guide table. And a distribution member having a large static friction coefficient with the surface side.

[0013]

The operation of the sorting apparatus of the photographic printer according to claim 1 will be described below.

Since the coefficient of static friction between the exposed surface side and the distribution member is larger than the coefficient of static friction between the non-exposed surface side of the photosensitive material and the guide table, the distribution member of the photosensitive material on the guide table. When it moves along the distribution direction while being in contact with the exposure surface side, the photosensitive material slides on the guide table and moves integrally with the distribution member as the distribution member moves. Therefore, a plurality of photosensitive materials can be distributed to a plurality of rows by sequentially moving the photosensitive material by the distribution member.

Then, the sorted photosensitive material is processed while being conveyed in the photographic printer.

Therefore, it is not necessary to dispose a large sorting table slidably, and it is not necessary to employ a complicated and expensive mechanism for the driving mechanism of the sorting table. Along with this, there is no need for a large space in the photographic printer to distribute the photosensitive material, and it is easy to downsize the device.

The operation of the sorting apparatus of the photographic printer according to claim 2 will be described below. This claim also has the same effect as that of claim 1, but uses a ferromagnetic material as the guide and a plastic magnet formed by mixing a magnet material in a resin material as the distributing member. Since there is no need for a solenoid or the like to press the sorting member against the guide, the mechanism of the sorting device is further simplified.

The operation of the photographic printer according to claim 3 will be described below. Similarly to claim 1, since the coefficient of static friction between the exposed surface side and the distribution member is larger than the coefficient of static friction between the non-exposed surface side of the photosensitive material and the guide table, the distribution member is placed on the guide table. In the state of being in contact with the exposed surface side of the photosensitive material, the photosensitive material moves integrally with the distributing member while sliding on the guide base along with the movement of the distributing member. Therefore, a plurality of photosensitive materials can be distributed to a plurality of rows by sequentially moving the photosensitive material by the distribution member.

Then, the photosensitive material after being exposed and sorted is sent to the developing processing section while being conveyed, and is subjected to the developing processing.

Therefore, similarly to the first aspect, it is not necessary to slidably dispose a large sorting table, and it is not necessary to employ a complicated and expensive mechanism as a driving mechanism of the sorting table. Along with this, there is no need for a large space in the photographic printer to distribute the photosensitive material, and it is easy to downsize the device.

FIG. 1 schematically shows a printer processor 10 which is a photographic printer according to an embodiment of the present invention. The photo printing unit 12 that constitutes the printer unit of the printer processor 10 has a structure in which the paper magazine 14 in which the printing paper P is stored can be loaded.

On the upper left side of FIG. 1 of the paper magazine 14, a drive roller 16 around which the vicinity of the front end of the photographic printing paper P is wound is rotatably supported. The driving roller 16 receives the driving force and rotates. Further, a pair of nip rollers 18 is arranged at a position facing the drive roller 16 with the printing paper P interposed therebetween.

On the other hand, in the photo printing unit 12, the motor 20
The cutter 22 which is operated by is installed, and the cutter 22 immediately cuts the photographic paper P coming out from the paper magazine 14.

In FIG. 1, a support base 46 is arranged on the right side of the cutter 22 on the downstream side in the transport direction of the printing paper P. A winding roller 52 around which the endless belt 44 is wound is arranged between the support base 46 and the cutter 22. Further, a nip roller 54 that holds the endless belt 44 between the winding roller 52 and the winding roller 52 is arranged above the winding roller 52.

A guide roller 56 around which the endless belt 44 is wound is arranged on the downstream side of the support base 46 in the conveyance direction of the printing paper P. Furthermore, the endless belt 44
Is wound around the tension roller 62 below the guide roller 56, and the guide roller 56 is driven and rotated by the driving force of a motor (not shown) to rotate the endless belt 44 in the clockwise direction in FIG.

On the other hand, the endless belt 44 has a large number of small holes 45 (shown in FIG. 2) formed over the entire area thereof, and a part of the endless belt 44 is placed on the upper surface of a support base 46. Has a large number of holes (not shown) corresponding to the small holes 45 of the endless belt 44. Furthermore, the communication duct 6
6 is connected to this support base 46. The communication duct 66 includes a fan box 7 provided with a suction fan 68.
Connected to 0.

On the other hand, above the endless belt 44 moving on the support base 46, an easel device 64 for printing an edged image on the photographic printing paper P is provided.

The casing 10A constitutes the outer frame of the printer processor 10. In particular, the upper surface of the photo printing unit 12 is formed by the work table 11, and the light source 26 is installed on the work table 11. .

On the left side of the light source 26 in the figure, C, M, Y
A diffusion box 28 is arranged so as to sandwich the CC filter 24 composed of three sets of filters, and the diffusion box 28 diffuses the light from the light source 26. The exit side of the diffusion box 28 faces the negative film N on the negative carrier 30 arranged on the work table 11.

From the above, the light beam generated by the light source 26 is C
After passing through the C filter 24, it is diffused by the diffusion box 28 and passes through the negative film N on the negative carrier 30.

On the other hand, as shown in FIG.
The optical axis S of the light beam is placed in the photoprinting section 12 directly below 0.
A prism 36 and a zoom lens 38 are attached so as to be respectively arranged above.

Therefore, the light rays that have passed through the negative film N and become the exposure light rays pass through the prism 36 and then through the zoom lens 38 whose magnification can be changed, and are then printed under the easel device 64. An image of the negative film N is formed on the paper P.

A density measuring device 40 for measuring the density of the negative film N is arranged in the photographic printing section 12, and a light beam bent in the horizontal direction by the prism 36 is sent to the density measuring device 40. It is like this.

Further, in the optical path between the zoom lens 38 and the easel device 64, there is a black shutter 41 which prints and exposes the light, whose color and intensity are adjusted by the CC filter 24 and which has passed through the negative film N, for a predetermined time. It is provided.

Since the photographic printing section 12 is structured as described above, the photographic printing paper P sent from the paper magazine 14 is cut to a desired length by the cutter 22 and then placed on the endless belt 44. It is conveyed to an image printing position, which is a position on the optical axis S of the exposure light beam. When the black shutter 41 is opened for a predetermined time, the exposure light beam from the light source 26 side reaches the photographic printing paper P via the prism 36, the zoom lens 38, etc., and the image recorded on the negative film N is printed on the photographic printing paper P. The portion where the image is printed is the image portion.

At this time, the air in the support base 46 is sucked by the suction fan 68 and blown out to the outside.
Are attracted to the endless belt 44 as indicated by arrow A.
Therefore, the photographic printing paper P is not only simply placed on the endless belt 44 but also sucked toward the endless belt 44 side, so that the photographic printing paper P is reliably conveyed by the endless belt 44, and
It will be arranged horizontally on the image printing position.

Further, the photographic printing paper P on which the image printing has been completed
Is sent out from the support table 46 by the endless belt 44 onto the steel table 112 which is a guide table made of steel, which is a kind of ferromagnetic material.

As shown in FIGS. 2 to 6, a ball screw 11 rotatably supported on the steel base 112.
The arm 116 is attached via 4 and the motor 118 connected to the ball screw 114 rotates the ball screw 114, thereby moving the arm 116.

Each arm 116 has an arm 1
Three rail holes 122 extending in the longitudinal direction of 16 are bored, and guide members 130A, 130B and 130C are arranged so as to be fitted into the rail holes 122, respectively.

On the other hand, three stepping motors 120 are respectively fixed to the base end side of the arm 116, and by driving and rotating these stepping motors 120, the wires 124 connected to the guide members 130A, 130B, 130C are rotated. Then, the individual guide members 130A, 1
30B and 130C are moved along the rail hole 122.

These guide members 130A, 130B, 13
In FIG. 6, solenoids 132 each having a plunger 134, which is a vertically allocating member, are attached to 0C. Here, on the surface of the plunger 134 facing the photographic paper P, for example, a rubber hardness test (A
It is attached with silicone rubber with a hardness of 30 degrees.

Therefore, the exposed surface side of the photographic printing paper P, which is the emulsion surface, and the surface of the plunger 134 on which the silicone rubber is attached, face each other, and the non-exposed surface, which is the surface opposite to the emulsion surface. The side and the steel base 112 face each other. Then, from the coefficient of static friction between the non-exposed surface side and the steel base 112, the exposed surface side of the printing paper P and the plunger 134.
The coefficient of static friction between and is larger.

From the above, as shown in FIG. 2, the photographic printing paper P is conveyed by the endless belt 44 to the place where the photographic printing paper P rides on the steel table 112. Plunger 134
The photographic paper P from the exposed surface side of the photographic paper P with the steel stand 112.
Hold between and. Then, the stepping motor 120 corresponding to the guide material 130A is rotated, and is slid to the right along the rail hole 122 in FIG. 2, which is the distribution direction, so that the non-exposed surface side of the printing paper P is placed on the steel table 112. Slide the photographic paper P to the position shown in FIG.

As shown in FIG. 3, when the second printing paper P arrives, it is similarly pressed by the plunger 134 of the guide material 130B and moved to the position shown in FIG. Further, as shown in FIG. 4, when the third printing paper P arrives, it is similarly pressed by the plunger 134 of the guide material 130C, and the printing paper P is moved to the position of FIG.

In this way, the processor unit 72, which is the developing unit, completes the exposure for one row in the range where parallel processing is possible,
When the printing paper P is stored on the steel base 112, the ball screw 114 is rotated by the motor 118 while the printing paper P is held between the steel base 112 and the steel base 112 by the plunger 134, and the steel base 112 and the printing paper P are separated from each other. The arm 116 is moved while sliding between them, and the three printing papers P are simultaneously guided to the processor side as shown by the chain double-dashed line in FIG.

That is, by utilizing the difference in static friction coefficient,
The conveyed printing papers P are sequentially arranged in any one of the three rows on the steel table 112, and are conveyed to the processor section 72 side. As a result, the photographic printing paper P can be transported with higher efficiency than when the photographic papers P are transported in one line in the processor unit 72. However, when the wide photographic printing paper P is transported, it is naturally transported in one line.

After that, the photographic printing paper P is printed with a plurality of rollers 140.
Development, bleach-fixing,
It is conveyed to the processor unit 72 which performs each process of washing and drying.

Next, the operation of this embodiment will be described. Since the coefficient of static friction between the exposed surface side and the plunger 134 is larger than the coefficient of static friction between the non-exposed surface side of the printing paper P and the steel table 112, the plunger 134 is
In the state of being in contact with the exposed surface side of the photographic printing paper P on 12,
When moving along the sorting direction, the photographic printing paper P slides on the steel base 112 and moves integrally with the plunger 134 as the plunger 134 moves. Therefore, the photographic printing paper P is sequentially guided by the guide materials 130A, 130B, 130C.
The plurality of printing papers P can be sorted into a plurality of rows by moving with the plunger 134.

Then, the sorted printing papers P are processed while being conveyed in the processor section 72.

Therefore, it is not necessary to dispose a large sorting table slidably, and it is not necessary to employ an expensive mechanism for the driving mechanism of the sorting table, so that the cost can be reduced. Along with this, a large space is not required in the printer processor 10 for allocating the printing paper P, which facilitates downsizing of the device.

Further, the printing paper P is prevented from concentrating only at a specific position in the processor section 72, and the printing paper P
It becomes difficult to cause uneven processing. Further, when processing the photographic paper P in the processor unit 72, it is not necessary to divide the transport path for each of the photographic paper P distributed, so that the maximum width that can be processed in the processor unit 72 is irrespective of the print size. The printing paper P can be processed freely.

In the present embodiment, when processing a large-sized printing paper P, all the guide materials 130A, 1A
It is not always necessary to use 30B and 130C, and one guide member may press the photographic printing paper P and move it to the center of the transport path.

Further, in this embodiment, after the photographic printing paper P is sorted, the transport path is bent by 90 °. However, the structure may be such that the arm can be swung, and the arm may be rotated by 90 ° and transported. In addition, the processor unit 72 is arranged in a right angle direction,
It can also be conveyed in the same conveying direction.

A second embodiment of the sorting apparatus for a photographic printer according to the present invention is shown in FIGS. 7 and 8, and this embodiment will be described based on these figures. The same members as those described in the first embodiment are designated by the same reference numerals, and the duplicate description will be omitted.

As shown in FIGS. 7 and 8, this embodiment uses a steel roller 152 made of steel which is rotated by a drive source (not shown) instead of the steel base 112.

At both ends of the steel roller 152,
Arms 154 that are rotatably supported around support shafts 156 are arranged, respectively.
A ball screw 158 is arranged so as to connect between one end sides of the.

The ball screw 158 is screwed with a bushing 164 in which a nipping roller 162 which is a distribution member capable of contacting the steel roller 152 is rotatably arranged on the outer peripheral side. This bush 164 has bush 1
A motor 166 for rotating 64 itself is attached,
By rotating the bush 164 on the ball screw 158 by the motor 166, the bush 164 and the sandwiching roller 162 can be moved along the ball screw 158.

On the other hand, the other ends of the pair of arms 154 are respectively connected to the plungers 170 of the solenoids 168, and the coil springs 172 are connected to the solenoids 168.
Is intervened between. Therefore, when the other end of the arm 154 is pulled down by the operation of the solenoid 168,
A nipping roller 162 arranged on one end side of the arm 154
Moves away from the steel roller 152, but the solenoid 1
When 68 is not operated, the nipping roller 162 moves the steel roller 152 by the urging force of the coil spring 172.
Is in contact with.

The material of the nip roller 162 is JI.
A rubber having a hardness of 9 to 30 degrees in a rubber hardness test (type A) by S is preferable, and in this embodiment, an EPDM of 25 degrees is particularly preferable.
A system synthetic rubber roller was used.

Therefore, as in the first embodiment, the exposed surface side of the printing paper P and the holding roller 162 face each other, and the non-exposed surface side and the steel roller 152 face each other. To do. The static friction coefficient between the exposure surface side of the printing paper P and the nipping roller 162 is larger than the static friction coefficient between the non-exposed surface side of the printing paper P and the steel roller 152.

As described above, the printing paper P on which the image has been printed is sent out from the support base 46 by the endless belt 44 onto the steel roller 152, which is a guide base.
7 and FIG.
As shown in (A), the nipping roller 162 nips the printing paper P with the steel roller 152.

The nip roller 162 is connected to the motor 16
6, the ball screw 158 is moved in the upper right direction in FIG. 7, for example, and the printing paper P is distributed. At this time, since the printing paper P is sandwiched between the steel roller 152,
The nipping roller 162 moves while the non-exposed surface side of the printing paper P slides on the steel roller 152.

As a result, the printing paper P sandwiched between the steel roller 152 rotated by the drive source and the sandwiching roller 162 which is in contact with the steel roller 152 and integrally rotates, is sent to the processor section 72. Will be done.

When the second sheet of photographic paper P arrives, the nip roller 162 causes the solenoid 1 to move, as shown in FIG. 8 (B).
By the operation of 68, the paper is once separated from the steel roller 152, moved to the central position on the ball screw 158, and the operation of the solenoid 168 is stopped, so that the photographic paper P is similarly pinched. After that, the photographic printing paper P is moved to the position in the lower left direction in FIG. 7, and is sent to the processor unit 72.

When the third printing paper P arrives, the nipping roller 162 is again moved to the center position in the same manner, and the printing paper P is nipping similarly. And this time,
The processor unit 7 is used as it is without moving the nip roller 162.
It will be sent to 2.

Next, the operation of this embodiment will be described. As in the first embodiment, the nipping roller 162 is the steel roller 1
52, in contact with the exposed side of the photographic paper P,
When the printing paper P moves along the sorting direction, the printing paper P slides on the steel roller 152 and moves integrally with the holding roller 162 as the holding roller 162 moves. Therefore,
By sequentially moving the photographic paper P by the nip roller 162, the plurality of photographic paper P can be sorted into a plurality of rows.

Then, the sorted printing paper P is processed while being conveyed in the processor section 72.

Therefore, as in the first embodiment, it is not necessary to slidably arrange a large sorting table, and it is not necessary to use an expensive mechanism as a driving mechanism of the sorting table. Along with this, a large space is not required in the printer processor 10 for allocating the printing paper P, which facilitates downsizing of the device.

In the above embodiment, the nipping roller 16
Although the number of 2 is set to one, a plurality of two or more may be used. By using a plurality of lines in this way, it is possible to speed up the sorting process.

Further, as the material of the sandwiching roller 162 used in the above embodiment, the material of the paper feeding roller used for feeding the paper of the printing apparatus is also suitable. For example, RT
V silicone rubber, foamed sponge rubber, Nosolex rubber manufactured by Nippon Zeon Co., Ltd. may be used, and further, Microcell Polymer Roll (trade name, ENDUR-C) manufactured by Inoac Corporation is also suitable.

Further, in order to stably slide the printing paper and to keep the nip force between the nipping roller 162 and the steel roller 152 constant, a plastic magnet formed by mixing a magnet material in a resin material is used. May be.

In this case, the nipping force of an actuator such as a solenoid is not used for completely nipping, but the nipping roller 162 may be simply dropped on the steel roller 152 which is a ferromagnetic material. That is, in this case, the photographic printing paper can be held by the magnetic force of the magnet with a constant weight, and a solenoid or the like for pressing the holding roller 162 against the steel roller 152 is not necessary.

Further, a soft material such as rubbers and elastomers, or a material having a large static friction coefficient such as nylon is suitable for the surface of the plunger 134 facing the printing paper and the outer peripheral surface of the holding roller 162.

On the other hand, the materials of the steel base 112 and the steel roller 152 are polyacetal resin, urea resin,
Suitable are melamine resin, phenol resin, high molecular weight polyethylene resin, resin containing fluorine atom, steel and stainless steel. Further, the surface of the material may be coated with a fluorine compound for reducing the frictional force.

Further, the photographic printing paper P sorted according to the above-described embodiment of the present invention is processed by the processor section 72, dried and sent to the sorter, and is generally dropped on a stacking belt or a conveyor to be stacked. It However, it is conceivable to adopt a sorting device similar to that of the above-described embodiment as a device for accumulating photographic paper, and dispose this allocating device instead of the accumulating belt or the conveyor to accumulate the photographic paper P. In this case, the photographic printing paper P, which is sorted and processed by the processor unit 72 and comes out of the processor unit 72, is guided to the guide table of this sorting device, and the sorting device performs an operation reverse to that of the above-described embodiment to print. The paper P is collected.

That is, in the conventional printing paper stacking method, the printing papers are dropped and collected on the stacking belt or the conveyor by gravity, so that the papers are likely to be misaligned. However, if a sorting device similar to the above embodiment is adopted, Since the exposure surface side is in close contact with the movable sorting member for stacking, the printing papers can be neatly aligned and stacked.
