Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for developing and processing photographic film, and more particularly to a method for accumulating film after processing.

[0002]

2. Description of the Related Art A photographic film, which is a 35 mm film, enables continuous shooting of a large number of frames such as 36 or 24 images, and is easy to handle because it is not as long as a motion picture film, and is widely popular. ing.

The development process of photographic film is generally carried out by an automatic developing machine in order to stabilize the process and enable a large number of processes.

In the automatic processor, a developing tank, a bleaching tank, a fixing tank,
It has a mechanism in which stable or washing tanks are arranged in order, and the photographic film is processed while being sequentially conveyed by a conveying means, dried through a drying section and discharged.

In order to convey a photographic film, it is generally performed that a leader for smoothly curling a photographic film, which is easily curled, is attached to the tip, and a conveying force is transmitted to the leader to convey the photographic film. . This leader is thicker than a photographic film and mainly uses a sheet-like resin having a strong rigidity, and its dimensions are often a little wider than the photographic film, and its length is set appropriately.

[0006] The conveying means employs a system in which the conveying force is transmitted to the leader by a sprocket, a toothed belt or the like.

The leader is also used to align and suspend the photographic film when it is carried out after the development processing. This is a method in which a photographic film connected to the leader is supported by a leader receiver provided in the discharge section and hung down.

Although the length of the leader is appropriately set depending on the structure of the automatic developing machine, a particularly short one is called a short leader and tends to be distinguished.

In the case of the short leader, as described above, there is an advantage that the alignment is good when supported by the leader receiver.

When the lower end of the photographic film discharged in this way and suspended in the discharge part has such a length as to come into contact with the bottom part or the floor, dust or the like adheres to the photographic film or the film members are entangled with each other. However, there was a problem that it was easily scratched and scratched.

The reason why the lower end of the photographic film has a length in contact with the bottom and the floor as described above is that the length of the automatic developing machine is 1500 mm or more in the example of taking 36 sheets of the 35 mm film described above. This is because, when the operability is important, the photographic film cannot be set high enough so that it does not touch the floor.

Under these circumstances, there is a demand for a film collecting method in which the lower end of the discharged film does not come into contact with the floor or the bottom while reducing the height of the automatic processor.

[0013]

In view of the drawbacks of the prior art, even if the height of the automatic developing machine is low, the processed photographic film can be aligned and stored without contacting the floor or bottom. An object of the present invention is to provide an accumulation method and an automatic processor.

[0014]

In order to achieve the above object, the film collecting method of the invention according to claim 1 is such that a long photographic film is connected to the rear end of the short leader and successively dipped in a processing solution. In an automatic developing machine for developing and drying and discharging the discharged photographic film, the short leader is supported by the short leader receiver, and the lower film receiver and the upper turn roller bend the photographic film in the traveling direction. It is characterized by being suspended.

According to a second aspect of the present invention, in the film stacking method, the short leader discharged from the film discharging section is guided ahead of the path of discharging the film with the short leader in the film discharging section of the automatic developing machine. A short leader receiver to be received, a lower film receiver provided below the short leader receiver, and a half of the distance between the curved portion of the short leader receiver and the wall surface of the automatic developing machine, which is above the lower film receiver. It is characterized in that a film is bent and suspended between a film support member including an upper turn roller having a center near a wall surface of an automatic processor.

Furthermore, in the film collecting method according to the third aspect of the present invention, the vertical height H of the upper turn roller is
It is characterized by having a relationship of H ≧ (1600−h) / 3 when the height difference between the inflection part of the short leader receiver and the upper turn roller is h.

According to a fourth aspect of the film collecting method of the present invention, the upper turn roller of the first or third film collecting method is pivotally supported by an arm, and the arm is rotatably supported by a pivot shaft. It is characterized in that the upper turn roller can be swung about the support shaft so as to move toward and away from the side wall of the automatic developing machine.

The automatic developing machine according to the invention of claim 5 is
The film collecting method according to any one of claims 1 to 4 is applied.

[0019]

In the present invention, the short leader is wider than the photographic film, is attached to the leading end of the photographic film by means such as adhesion, and passes through the conveying means in the form of leading the photographic film.

In the present invention, when the short leader discharged from the automatic developing machine reaches the short leader receiver, the progress of the short leader is stopped and the succeeding photographic film hangs downward. At this time, since the discharging operation of the automatic developing machine is still continuing, the sag of the photographic film extends downward in a U-shape convex downward,
The letter-shaped lower end reaches the lower film receiver and is prevented from extending downward. Since the U-shaped descent is arranged between the short leader receiver and the upper turn roller, the lower end of the U-shaped sag as described above reaches the lower film receiver, and The subsequent photographic film, which is prevented from extending downward and continues to be discharged from the automatic processor, comes into contact with the upper turn roller and bends along the peripheral surface of the upper turn roller. The trailing edge of the photographic film that has started to droop again between the roller and the side wall of the automatic processor and has finished discharging from the automatic processor falls between the upper turn roller and the side wall of the automatic processor, Suspended by the upper turn roller and hanging down.

As described above, since the leading end of the photographic film is supported at the position of the short leader receiver above and suspended twice in the air while being bent twice, the lower end of the photographic film comes into contact with the floor or the bottom of the automatic processor. Therefore, it is possible to prevent dust and dirt accumulated on the floor or bottom from adhering to or scratching the photographic film.

In the above description, the suspension from the discharge of the first photographic film with the short leader has been described, but the automatic developing machine does not end with one processing, but enables a plurality of continuous processing. From the above, the photographic film with the short leader is successively discharged after the discharged and suspended photographic film. That is, when the trailing edge of the first photographic film with a short leader leaves the drive of the automatic processor and falls as described above, the discharge of the second photographic film with a short leader is started and the short leader of the leading edge is the same as above. And the following photographic film is guided to the already suspended first photographic film with a short leader and is accommodated in an overlapping manner.

Since the photographic films with short leaders, which are discharged one after another in this manner, are stacked and aligned and suspended,
Since they do not shake and do not rub against each other, scratches can be prevented.

Since the photographic films discharged from the automatic developing machine are sufficiently dried, they do not adhere to each other even when they are suspended and stacked as described above.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, a detailed description will be given of embodiments with reference to the drawings.

FIG. 1 is a sectional view of an automatic developing machine for photographic film, to which the film collecting method of the present invention is applied.

First, the processing process of the photographic film will be described.

The photographic film F, which has been photographed, has a short leader 13 attached to the leading end thereof and is inserted from the inlet on the left side of the automatic developing machine 1, and has a developing tank 9, a bleaching tank 19, a fixing tank 10,
The washing or stabilizing tank 11 is sequentially processed by a conveying means, is sufficiently dried in a drying section 12, and is discharged to a discharging section 2 by an exit roller 3. The short leader 13 attached to the leading end of the discharged photographic film advances to the right on the guide 4, reaches the inflection portion 5, changes its direction upward, and stops while leaning on the short leader receiver 6. Since the photographic film connected to the short leader 13 is gradually fed out by the feeding force of the outlet roller 3, the photographic film continues to hang downward in a U shape in accordance with the hole in the center of the guide 4 to form a first loop, forming a U shape. When the lower end of the shape contacts the lower film receiver 7 and further lowering is prevented, the photographic film bends along the upper turn roller 8 and the upper turn roller 8
A U-shaped dangle is formed on the left side of the photographic film, but the trailing edge of the photographic film comes out from the output roller 3 and hangs down as shown in the figure.

Since the distance A from the side wall 18 of the automatic developing machine to the center of the upper turn roller 8 is set to be smaller than the horizontal distance B from the center of the upper turn roller 8 to the inflection portion 5, The loop formation is smoothly performed, and the upper turn roller 8 does not interfere. This also allows
The upper turn roller 8 is arranged so as to smoothly suspend the latter half of the photographic film.

When the height from the center of the upper turn roller 8 to the bottom or the floor is H and the height difference from the center of the upper turn roller 8 to the inflection portion 5 is h, H ≧ Because of the relationship of (1600-h) / 3, the trailing edge of the photographic film suspended as shown in the figure does not reach the bottom or floor.

Next, FIG. 2 shows a second embodiment, in which the upper turn roller 8 is pivotally supported by an arm 15, and the arm 15 is pivotally supported.
It is rotatably supported by 16, and is capable of swinging about the support shaft 16 such that it approaches the side wall 18 of the automatic developing machine 1 or separates from it as shown in the drawing. The operation of the upper turn roller 8 will be described. First, until the photographic film reaches the outlet roller 3, the upper turn roller 8 waits in a state of being shifted to the left side in the figure (that is, in a state of being close to the side wall 18). N seconds after the photographic film starts to emerge from the exit roller 3 or when the photographic film droops in a U shape and its lower end is detected by the film detection sensor 17, the upper turn roller 8
Is moved to the right, the second half of the following film hangs down to the left of the upper turn roller 8. When the upper turn roller 8 is movable in this way, the distance A is set to B as described above.
The constraint of making it smaller may be removed.

In this way, long photographic film
The lower film receiver 7, the upper turn roller 8, and the short leader receiver 6 are suspended in the air and do not come into contact with the floor or the like. The upper surface of the lower film receiver 7 may be provided with protrusions or holes to promote the removal of dust so that dust and dirt do not adhere to the film.

Next, FIG. 3 shows the shape of the upper turn roller 8 in which the diameter of the roller is made thin at the center and the dimension C is 6
By setting it to 2.2 mm or more and less than 70.0 mm, the bending guideability of the photographic film is improved and the film misalignment is prevented.

FIG. 4 shows the sectional shape of the lower film receiver. By setting the width D to be 62.2 mm or more and less than 70.0 mm, the lower end of the photographic film hanging in a U shape can be supported without difficulty. The descent is stopped and the occurrence of scratches is prevented.

[0035]

As described above, according to the present invention, even if the height of the automatic processor is low, the processed photographic film can be stored in line without contacting the floor or the bottom. It is possible.
