DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a long photosensitive material connected via a splice, wherein a detection hole for detecting the splice is provided in the vicinity of the splice in the longitudinal direction of the photosensitive material. The present invention relates to a photographic processing apparatus capable of performing processing of the photosensitive material by mounting a photosensitive material storage magazine in which the photosensitive material formed as described above is stored in a roll shape.

[0002]

2. Description of the Related Art In such a photographic processing apparatus, a photosensitive material is exposed to a frame image of a negative film, or a digital image is exposed, and the exposed photographic material is developed and dried to be cut into a photographic print. To discharge outside the device. In order to process the photosensitive material, a magazine containing the photosensitive material is mounted at a predetermined position of a photographic processing apparatus.

[0003] In a photosensitive material storage magazine, a long photosensitive material is wound and housed in a roll shape, and the winding length may be as long as 100 or more tens of meters. In performing the photographic processing, predetermined processing is sequentially performed while the photosensitive material is pulled out from the photosensitive material storage magazine and transported. Ideally, the photosensitive material is accommodated in the photosensitive material accommodating magazine without a splice portion (connecting portion). However, in practice, the splice portion may be provided for reasons such as manufacturing.

Here, the splice will be described with reference to FIG. In FIG. 3, the front and rear portions of the splice portion are cut by a cutter (cutting means), and such a photosensitive material is referred to as a spliced portion-attached photosensitive material 3S. The photosensitive material 3S with a splice portion is provided with a splice portion 3b for splicing a long photosensitive material, and a detection hole 3a for detecting the presence of the splice portion 3b. The splice unit 3b splices the front and rear photosensitive materials by an appropriate method such as heat fusion.

The detection hole 3a is a hole formed along the longitudinal direction (conveying direction) of the photosensitive material, and has a length in the longitudinal direction x and a dimension in the conveying width direction y. The dimensions of the detection hole and the positional relationship from the splice portion 3b are defined by JIS and ISO standards.

Next, a brief description will be given of the structure of the conveying means provided in the vicinity of the discharge section among the conveying means of the photosensitive material 3 in the photographic processing apparatus. FIG. 5 is a side view of the transport unit T near the discharge unit 10, and FIG. 7 is a plan view of the transport unit T shown in FIG.

The photosensitive material is conveyed in the direction of the arrow in FIG. The transport means T includes a driving roller 39 and a pressure roller 40, a large-diameter roller 35 provided at a corner of the transport path, and a pair of pressure rollers 36 and 3 for pressing against the large-diameter roller 35.
7, a drive roller group 30 and a pressure roller group 31. As shown in FIG. 7, the pressing roller group 31 includes three pressing rollers 31a and 31 disposed along the conveyance width direction.
The pressure roller group 31 is supported by a support shaft 34. The drive roller group 30 also includes three drive rollers corresponding to the pressure rollers 31a to 31c.

The state of the photosensitive material 3S with a splice portion when it is conveyed will now be described. As shown in FIG. 5, the photosensitive material 3S is conveyed across the large-diameter roller 35 and the driving roller group 30, but is not a pressing roller group. The roller 31 is conveyed by the pressure roller 31a and the drive roller located at the center of the roller 31. The width h of the pressure roller 31a is set to be slightly smaller than the width y of the detection hole 3a (FIG. 7).

[0009]

Therefore, when the photosensitive material 3S with a splice is conveyed and the detection hole 3a reaches the position of the pressure roller 31a, the pressure roller 31a
Cannot transmit the transfer force. Even in such a case, the distance A between the end of the detection hole 3a and the end of the photosensitive material is sufficiently set so that the photosensitive material 3S with a splice portion can be reliably transported.
Even if the transfer force cannot be transmitted by a, the transfer force by the large-diameter roller 35 and the first pressure roller 36 on the upstream side can be transferred. That is, as shown in FIG. 5, the distance between the large-diameter roller 35 and the pressure roller group 31 is B, and A
If set to <B, photosensitive material 3S with splices
Cannot be transported. Therefore, at least A> B had to be satisfied.

The photosensitive material 3S with a splice portion cannot be used for printing and is discarded. It has been desired that the dimension A is reduced as much as possible to reduce the loss. Although it is conceivable to increase the width of the pressure roller 31a, as shown in FIG.
The large diameter rollers 32a to 32c are provided adjacent to 0a to 30c, and there is a limit in increasing the width of the pressure roller 31a.

A method of stopping the photographic processing of the photosensitive material 3S with a splice portion and removing the photosensitive material 3S with the splice portion from the inside of the apparatus can be considered, but the photographic processing operation is interrupted. Troublesome for.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a photographic processing apparatus capable of reducing the loss of photosensitive material.

[0013]

In order to achieve the above object, a photographic processing apparatus according to the present invention is a long photosensitive material connected via a splice section, wherein the splice section is located near the splice section. In a photographic processing apparatus capable of processing the photosensitive material by mounting a photosensitive material storage magazine in which the photosensitive material in which a detection hole for detecting a portion is formed in the longitudinal direction of the photosensitive material and the photosensitive material is stored in a roll shape is provided. Cutting means for cutting the photosensitive material drawn out of the photosensitive material storage magazine as a print of a predetermined size, and cutting the photosensitive material with a splice portion including the splice portion and the detection hole, and the cut photosensitive material. Transport means for transporting, and a transport roller provided in the transport means and having a width equal to or smaller than the width of the detection hole, Roller is characterized in that a width direction movement means for moving the splicing portion with the photosensitive material in the conveying width direction at a position not applied to the detection hole.

According to this configuration, a long photosensitive material is pulled out from the photosensitive material storage magazine mounted on the photographic processing apparatus, and is sequentially subjected to processes such as exposure. The long photosensitive material is cut to a predetermined print size by a cutting means in a processing step. The cutting means cuts a portion including the splice portion and the detection hole as a photosensitive material with a splice portion. The photosensitive material with the splice part
It is transported by transport means having narrow transport rollers, but it is designed to be transported in the state of being moved in the transport width direction by the width direction moving means, so that the narrow transport roller does not cover the detection hole It is moved in the width direction. In other words, the photosensitive material with the splice can be transported in a state where the detection hole is avoided, so that the transporting force of the transport roller can be reliably transmitted to the photosensitive material.

Therefore, the detection hole 3a as shown in FIG.
The distance A between the end of the photosensitive material 3S and the end of the photosensitive material 3S can be shortened, and the loss can be reduced.

As a preferred embodiment of the present invention, a sorting / conveying mechanism for switching the photosensitive material from a single-row conveying state to a multi-row conveying state is provided, and this sorting / transporting mechanism functions as the width direction moving means. Things are raised.

In order to enhance the processing capacity of the photosensitive material in the photographic processing apparatus, a sorting and transport mechanism for switching the transport state of the photosensitive material from one row to multiple rows may be provided. By making this sorting and transporting mechanism function as the width direction moving means, it is not necessary to provide a dedicated width direction moving means, thereby contributing to cost reduction and suppressing an increase in size of the apparatus.

By moving 0, paper 3 can be sorted into two rows. In the mechanism in FIG. 2, a configuration in which the data is divided into two rows is shown. However, the configuration is not limited to this, and a configuration in which the data is distributed into three rows or more rows may be employed.

<Structure of Conveying Means> Next, a brief description will be given of the structure of the conveying means T provided in the vicinity of the discharge section among the conveying means of the paper 3 in the photographic processing apparatus. FIG. 4 is a side view of the transport unit T near the discharge unit 10, and FIG. 4 is a plan view of the transport unit T shown in FIG. FIG. 6 shows FIG.
FIG. 4 is a front view of the conveying means T shown in FIG.

The transport means T includes a driving roller 39, a pressure roller 40, a large-diameter roller 35 provided at a curved corner of the transport path, a pair of pressure rollers 36, 37 for pressing the large-diameter roller 35, and a drive. A roller group 30 and a pressure roller group 31 are provided. The pressure roller 36 has a support shaft 38. As shown in FIG. 7, the pressing roller group 31 includes three pressing rollers 31a and 31 disposed along the conveyance width direction.
The pressure roller group 31 is supported by a support shaft 34. The drive roller group 30 also includes three drive rollers 30a, 30b, and 30c corresponding to the pressure rollers 31a to 31c (see FIG. 6). These drive rollers 30a to 30c and pressure rollers 31a to 31c function as transport rollers.

As shown in FIG. 6, each drive roller 30a,
Large diameter rollers 32a, 32b,
32 c is provided on the support shaft 33. Paper 3
Since the paper magazine 3p is accommodated in the form of a roll, the paper magazine 3p originally has the curl and the curl is formed in the same direction while passing through the drying unit 9. If the paper 3 is discharged from the discharge unit 10 while having such a habit, the paper 3 is discharged in a state where the leading end thereof hangs down, so that the subsequent sorting operation does not work.

Then, as shown in FIG. 6, the paper 3 is discharged from the discharge section 10 in a state where the paper 3 is forcibly deflected in the conveying width direction (the paper 3 is stiffened), so that the sorting operation of the discharged paper 3 is performed. Can be done properly. Since the mechanism for deflecting the paper 3 is employed in this manner, the width of the pressure rollers 31a to 31c cannot be increased. If the width is too large, the paper 3 is strongly held, stress is applied to the paper 3, and the paper 3 may be damaged.

<Transportation of Splice Paper> The transport of the splice paper 3S will now be described. When it is detected by the sensor 21 that the paper 3 pulled out from the paper magazine 3a has the splice 3b, the cutter 5 As a result, splice paper 3S having a predetermined size is formed. This splice paper 3S
Are not used for exposure, and therefore pass through the exposure table 6 as they are. At this time, the splice paper 3S is transported in the direction of the arrow as shown in FIG. 3, and the right side in FIG.

Next, when the sheet passes through the switchback mechanism, the sheet is conveyed in a state where the front and back are reversed and the left side in FIG. Then, when the splice paper 3S is sent to the sorting / conveying mechanism 17, the splice paper 3S is moved by a predetermined amount in the width direction. That is, the sorting and conveying mechanism 17 functions as a width direction moving unit.

At this time, the moving amount in the width direction is δ, and FIG.
Is shown in The splice paper 3S passes through the development processing unit 8 and the drying processing unit 9 while being moved in the width direction, and is discharged from the discharge unit 10 by the transport unit T. FIG. 4 shows the positional relationship between the splice paper 3S and the pressure roller group 31 at this time. Since it is moved by δ in the width direction, the central pressure roller 31a does not touch the detection hole 3a, and the two pressure rollers 31a,
31b is used to convey the spliced paper 3S at both ends in the width direction.

Accordingly, the splice paper 3S can be discharged from the discharge unit 1 without the help of the driving force of the large-diameter roller 35 located on the upper side of the driving roller group 30 and the pressure roller group 31.
It can be discharged from zero. Therefore, the dimension A shown in FIG. 3 can be shortened, and loss paper can be reduced.

<Another Embodiment> The photographic processing apparatus according to the present embodiment is an apparatus that projects and exposes a frame image of a negative film. However, the present invention is not limited to this, and the present invention is also applicable to a photographic processing apparatus that exposes a digital image to a photosensitive material. It can be applied.

2. In the photo processing apparatus to which the paper magazine is mounted, the present embodiment describes the paper magazine 3p in which the paper 3 having the splice is stored, but the paper magazine 3p in which the paper 3 without the splice is stored is mounted. Of course, it can be processed. 3. In the present embodiment, the cutter 5 as the cutting means is arranged on the upper side of the exposure table 6, but is not limited to this.
