2. Description of the Related Art In recent years, compact automatic developing machines called so-called minilabs have become widespread, and installation locations are not limited to places where people gather, such as supermarkets, game centers, retail stores, and station squares. Is coming. As a result, the amount of photosensitive material used has increased, and the frequency of new loading has also increased. To load a new photosensitive material,
It is necessary to load the magazine with sufficient consideration for shading.

However, since there are many amateurs in loading, it is inconvenient to load in a dark room. Therefore, in recent years, roll-shaped photosensitive material packages that can be loaded in a bright room have been proposed.

[0004] Conventionally, a black polyethylene bag has been used as a package for loading in a bright room. However, since it is inconvenient to load the magazine, a DL (Day L) is used.
A package packaged by a technique called “light loading” has been developed.

Conventionally, such a roll-shaped photosensitive material package is disclosed in, for example, Japanese Utility Model Publication No. 1-38582. This roll-shaped photosensitive material package,
As shown in FIG. 7A, a roll-shaped photosensitive material 4 in which a photosensitive material web 1 is wound around a cylindrical core member 2 and formed into a roll, and disposed on the flat side surfaces 3 on both sides of the roll-shaped photosensitive material 4 And a strip-shaped light-shielding cover 6 that covers the outer peripheral surface of the roll-shaped photosensitive material 4. . The light-shielding cover 6 is wider than the photosensitive material web 1 and the leader 7. When the outer peripheral surface of the roll-shaped photosensitive material 4 is covered, the side end portions 8 on both sides thereof project in the width direction of the roll-shaped photosensitive material 4. Further, a plurality of slits 9 are provided in the side end portions 8 on both sides thereof.

Then, the reader 7 is further wound around the roll-shaped photosensitive material 4 to the leading end, and is fixed with an end label 11 made of an adhesive tape or the like to prevent unraveling. Subsequently, the side surface light shielding member 5 is brought into contact with the side surface 3 of the roll-shaped photosensitive material 4,
The side end 8 of the light-shielding cover 6 is bent along the periphery of the side-surface light-shielding member 5 and adhered to the side-surface light-shielding member 5 to form a roll-shaped photosensitive material package 20 shown in FIG.

There is also a roll-shaped photosensitive material package disclosed in Japanese Utility Model Publication No. 56-16608. As shown in FIG. 8, the roll-shaped photosensitive material package 30 uses a light-shielding reader 12 having a light-shielding property instead of the light-shielding cover 6 used in the roll-shaped photosensitive material package 20 described above. As a side light-shielding member for shielding the side surface of the roll-shaped photosensitive material, a disk-shaped side cover 15 having an outer diameter larger than the outer diameter of both side surfaces 14 of the roll-shaped photosensitive material 13 and having a slit 17 in a peripheral portion 16 is provided. In addition, the peripheral portion 16 having the slit 17 is bent and adhered along the outer peripheral surface near the end of the roll-shaped photosensitive material 13. This configuration is different from the rolled photosensitive material package 20 described above, but the other portions have the same configuration.

There is also a roll-shaped photosensitive material package disclosed in Japanese Utility Model Laid-Open No. 6-6290. As shown in FIG. 9, the roll-shaped photosensitive material package 40 is different from the roll-shaped photosensitive material package 30 described above in that no slit is formed in the peripheral portion of the disk-shaped side light-shielding member 24. It is bent along the outer peripheral surface near the end of the roll-shaped photosensitive material and is adhered to the outer peripheral surface of the roll-shaped photosensitive material.

The rolled photosensitive material package 2
0, 30, and 40 are loaded in a magazine (not shown) in a bright room state and used for use.

[0010]

The light-shielding reader 120 is wound around the photosensitive material web 112 one or more times by a belt-like member whose width is equal to or slightly smaller than the width of the photosensitive material web 112 and whose length is equal to or greater than the outer periphery of the roll-shaped photosensitive material 110. One end thereof is joined to an end of a photosensitive material web 112 wound around the core 111 by a splice tape 113. Moreover, you may join by ultrasonic welding.

On the other hand, on the tip side of the light-shielding reader 120, a narrow portion 122 having a narrow shape is formed through a tapered portion 121 whose width is gradually narrowed from both ends near the tip toward the tip. Have been. The tapered portion 121 is preferably linear, and the angle γ with the edge of the light-shielding reader 120 is preferably 30 to 60 °, and most preferably 45 °.

The light-shielding reader 120 has a function as a peripheral light-shielding member for protecting the peripheral surface of the photosensitive material web 112 from light, moisture, dust and the like. Therefore, the packaging film material constituting the light-shielding leader 120 has sufficient light-shielding properties, moisture-proof properties and the above-mentioned relationship as the light-shielding leader 120, and has physical strength (such as hard to tear) having a relationship with a side light-shielding member described later. ) Is not particularly limited as long as it does not adversely affect the photosensitive emulsion on the photosensitive material such as fog, and various packaging film materials can be used. Further, in addition to the above properties, it is more preferable to use a packaging film material having a property that one surface is easily thermally bonded and the other surface is hardly thermally bonded. Specifically, a light-shielding polyethylene film containing carbon black, or a laminated film obtained by combining a light-shielding polyethylene film containing carbon black with paper, polyester, aluminum foil, or the like is preferable. The light-shielding reader 120 has a total thickness of 100 to 2 mm.
It is preferably about 00 μm.

Further, as shown in FIG. 1, a terminal label 140 formed of a removable adhesive tape is attached to the tip of the light-shielding reader 120. Is fixed to the outer peripheral surface of the light-shielding reader 120 to prevent unwinding. When the end label 140 is loaded into the magazine,
It is torn to release the unwinding prevention and pull out the light-shielding reader 120. For this reason, it is preferable to use a material having good tearability, particularly a paper label, as the material of the end label 140. Also, this terminal label 140
Although not shown, a symbol such as an arrow indicating the setting direction to the magazine, and a design such as data indicating a winding length and a width may be applied to the magazine.

The roll core 111, the photosensitive material web 112, the light-shielding reader 120 and the end label 140 constitute a roll-shaped photosensitive material scroll 100A.

The side light-shielding member 130 is provided at the end surface of the roll-shaped photosensitive material scroll 100A, specifically, at the core 11.
A portion larger than the outer diameter of the roll-shaped photosensitive material 110 which is adhered to the end face of the roll-shaped photosensitive material 110 by an emulsion-based adhesive or an adhesive tape or the like, or does not cover the side surface of the roll-shaped photosensitive material 110, that is, an excess peripheral portion d is joined to the end of the roll-shaped photosensitive material 110, and the outer periphery of the light-shielding reader 120 that covers the outer peripheral surface of the roll-shaped photosensitive material 110 by folding at a plurality of locations with crests and valleys substantially in the direction of the center. It is folded down along the surface, and is stuck and fixed to the outer peripheral surface of the light-shielding reader 120. The outer peripheral surface of the light-shielding reader 120 to which the peripheral edge d of the side-surface light-shielding member 130 is adhered and fixed is exclusively a wide portion of the light-shielding reader 120.
Is attached and fixed so as not to cover the outer peripheral surface of the narrow portion 122 on the distal end side. Therefore, as shown in the figure, the peripheral edge portion d of the side light shielding member 130 is attached and fixed so as to partially cover the tapered portion 121 of the light shielding reader 120.

It is preferable that the side light-shielding member 130 is adhered with an adhesive force that requires a force of 1 kgf or more when peeled from the end face of the roll-shaped photosensitive material scroll 100A in the 90 ° direction. If the rolled photosensitive material 110 is adhered with a smaller force than this, if the rolled photosensitive material 110 is displaced and becomes a so-called bamboo shoot, the side surface light shielding member 1
It is not preferable because the light-shielding property may be released due to the peeling of 30.

The bending of the peripheral edge d of the side surface light shielding member 130 can be performed mechanically, and in detail, the means described in Japanese Patent Application No. Hei 9-117007 can be employed.

The side light shielding member 130 has a sufficient light shielding property,
It must have bendability, guarantee that there is no pinhole, and strength characteristics. Therefore, the side light-shielding member 130 has a good bending property, and has a tear strength close to both the longitudinal and transverse directions, so that the adhesive portion with the light-shielding reader 120 is easily torn. 150% or less, tensile strength 2
00 kg / cm or less, a tear strength of 20 g or more and 50 g or less, and a tensile strength and a tear strength which are weaker in a circumferential direction and in a width direction of the light-shielding reader 120.
Among them, it is particularly preferable to form a material having a tear strength of 50% or less so as to have a total thickness of 200 μm or less.

In the present invention, the side light shielding member 130 is
The conductive material is made of a conductive material, and examples of the conductive material include a conductive metal plate. Among them, an aluminum plate is preferable in terms of performance, weight, price, and the like.

As the conductive material, a material obtained by laminating an aluminum foil on a base material can be used. As the base material, paper containing or impregnated with conductive fine particles or conductive fine powder, for example, paper impregnated with carbon black can be used.

Such a conductive material preferably has a surface specific resistance of 10 ¹³ Ω or less. If it exceeds this, the effect of releasing the charge charged on the roll-shaped photosensitive material package 100 is insufficient.

When the side light-shielding member 130 is formed of a conductive material, the electric charges charged on the package 100 and the photosensitive material are discharged from the side light-shielding member 130 or discharged by another discharging means to remove static electricity. The adverse effect on the photographic performance of the photosensitive material due to the occurrence can be prevented. At the time of static elimination, as will be described later, a method in which the package 100 is released to the magazine side where the package 100 is loaded may be used.

As another preferred embodiment of the present invention, FIG.
As shown in FIG. 7, when the above-described laminate of the conductive metal plate 130a and the paper 130b is used as the side light shielding member 130, the paper 130b is disposed on the side in contact with the photosensitive material, and It is also preferable to provide one or more through-holes h in 130b, and to form the conductive coating layer 130c while filling the through-holes h on the upper surface of the paper 130b.

In another preferred embodiment of the present invention,
The core 111 in contact with the photosensitive material is formed of a conductive material as described above.

It is more preferable that both the side light shielding member 130 and the core 111 in contact with the photosensitive material are formed of a conductive material.

As shown in FIG. 2, a back member 131 made of black paper impregnated with a conductive material such as carbon black is provided between the side light-shielding member 130 and the end surface of the roll-shaped photosensitive material 110. Is preferably interposed.
The back surface member 131 is preferably bonded in advance to a surface of the side surface light shielding member 130 facing the end surface of the core 111. By using a black light-shielding material for the back surface member 131, the light-shielding property can be improved.
Is further strengthened than when used alone. Further, by impregnating with a conductive material such as carbon black, the conductive material becomes a component of the conductive material integrally with the side surface light shielding member 130, and the static electricity removing function of the side surface light shielding member 130 can be maintained.

The back member 131 is a side light shielding member 130.
And the outer diameter of the side surface light-shielding member 1
30 and is larger than the outer diameter of the roll-shaped photosensitive material 110. Therefore, there is an advantage that the adhesive does not adhere to the end surface of the photosensitive material web 112 even if the adhesive is applied to the back of the side light shielding member 130.

In FIG. 1, reference numeral 150 denotes a label material for close contact made of an adhesive tape or the like.
A part of the narrow portion 122 on the distal end side of the light-shielding reader 120 with respect to a tearing start portion (a portion where the peripheral edge d of the side-surface light-shielding member 130 and the tapered portion 121 intersect) to pull the side light-shielding member 130 by pulling 0 Affixed over the edge at. Thus, for example, when the roll-shaped photosensitive material package 100 is loaded into the magazine, the operator mistakenly pulls the light-shielding reader 120, and the tearing start portion where the peripheral edge d of the side light-shielding member 130 and the tapered portion 121 intersect. It is possible to avoid a situation in which the peripheral edge portion d is broken and the light-shielding property is released due to a direct pulling force acting on the peripheral portion d.
