Abstract

PURPOSE:To facilitate stripping operation of a light shielding mateial in the stage of stripping off the light shielding material from a light shielded container by bonding the light shielding container to the light shielding material so as to concentrate a stripping force to one point at at least the beginning of stripping. CONSTITUTION:A film package 10 is constituted of a light shielding container 14 for housing sheet film 12 and a strippable covering mateial 18 which shields light tightly to keep the film 12 isolated from light by covering an opening part 14a of the container 14. Since a bonded part 20a is formed obliquely to a direction orthogonal to the stripping direction of the material 18, the stripping force is concentrated in the first stage to one point of the oblique part 20, and the material 18 is stripped gradually from an end side of an end edge part 14b of the container 14 toward another end side. As the result, the material 18 is stripped without requiring relatively large tensile force. As described above, the light shielding material is stripped off very easily with small tensile force, and deterioration of light shielding effect before breaking seal is prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sheet film package, and more particularly, to a sheet film package configured such that a light-shielding member covering an opening of the light-shielding container can be easily peeled off from a light-shielding container housing the sheet film. Regarding the package.

A radiation image is recorded on an X-ray film by irradiating a human body or other object with radiation, and this is used for medical diagnosis, etc.
2. Description of the Related Art vA imaging devices have been widely used. In this case, the xIJi film is loaded into the X-ray imaging device in a light-shielded state, and the emulsion surface of the film is directly irradiated with X-rays to record an image of the subject.

By the way, recently, a radiation image recording and reproducing system has been developed that uses a storage phosphor (stimulable phosphor) to record radiation i3 hyperimages of a subject, and it has been used in the medical field as described above. I'm starting to rebel against the desk.

Here, a storage phosphor refers to a phosphor that, when irradiated with radiation (X-rays, α-rays, β-rays, R-rays, electron beams, ultraviolet rays, etc.), accumulates a part of this radiation energy and later emits visible light. A phosphor that exhibits stimulated luminescence according to the energy accumulated by irradiation with excitation light.

The radiation image recording and reproducing system described above utilizes this stimulable phosphor, in which radiation image information of a human body, etc. is recorded once on a sheet having a layer made of the stimulable phosphor, and then the stimulable phosphor sheet is is scanned with excitation light such as a laser beam to generate stimulated luminescence light, the resulting stimulated luminescence light is read out photoelectrically to obtain an image signal, and based on this image signal, recording on photographic light-sensitive materials, etc. The image is output as a visible image on a material, CRT, etc.

Here, when recording an image on a recording material, an image recording device, for example, an image output laser printer device is employed. The photosensitive sheet film (recorded by this device divided by 4 times 1) is stored in a package, etc., and the film is taken out one by one by a sheet-fed mechanism including a suction cup, etc.
A predetermined image is recorded by irradiating the film with a laser beam based on an electric signal obtained from the g4 phosphor sheet. Then, this film J is transported into an automatic developing device, and after undergoing a developing process, is stored at a predetermined location or is directly provided for diagnosis or the like.

Incidentally, in the image output laser printer device, like the conventional X-ray imaging device described above, external light must not be irradiated on the film J when loading the film into the device, but operability can be improved. It is desirable to increase the film loading capacity in a bright room, and various bright room loading methods are known to make this possible.

However, in the conventional bright room loading method, the film package is stored in a special magazine, this magazine is loaded into a device, and then the package is cut or otherwise loaded into the device. It can be taken out. Therefore, a dedicated magazine is required and must be made strong enough to withstand repeated attachment and detachment, and therefore the dedicated magazine itself has a considerable weight. As a result, a drawback arises in that it is troublesome for the operator to attach and detach the dedicated magazine. Moreover, since the dedicated magazine is provided with a shutter mechanism and the like, it becomes quite expensive. In particular, when using various films of different sizes, it is necessary to prepare a dedicated magazine for each size of film, which significantly increases manufacturing costs and is inconvenient in that it is not economically acceptable in practice. is pointed out.

In view of the above-mentioned inconvenience, the present applicant has developed a film package in which a flexible light-shielding cover member is attached in a peelable manner to the opening of a light-shielding container in which multiple films are stacked and stored without using a dedicated magazine. We proposed a bright room loading method in which the film package itself was directly loaded into the equipment (Japanese Patent Application No. 1986-2024, old issue No. 60-202).
No. 442 and the patent filed on the same day (=1) as the present application (
1)).

FIG. 1 shows a preferred example of a film package used in the bright room loading force method proposed by the present applicant.

That is, this FILNO package 2 stores a sheet-like film 6 stacked inside a light-shielding container 4, and the light-shielding container 4
By adhering a removable light-shielding cover member 8 to the opening 4a in the state shown by the two-dot chain line, the film 6 is held light-tight.

Here, the light-shielding container 4 and the cover member 8 are bonded together in such a manner that the adhesive portion 7 on the periphery of the opening 1'' portion 4a and the adhesive portion 9 on the periphery of the cover member 8 are releasable when the film 6 is used to shield light. has been done. Further, the cover member 8 is configured to be slightly longer than the length in the longitudinal direction of the light-shielding container 4, and its edge portion 8a is curved upward and is not adhered to the light-shielding container 4. .

The film package 2 thus configured is loaded into the image output laser printer device from the edge 4h side of the light-shielding container 4 with the film 6 light-tightly held by the cover member 8, and the cover member 8 is inserted into the image output laser printer device. Bt is gradually peeled off from the light-shielding container 4 from the edge 8a, and the opening 4a is opened into the device. The solid line in FIG. 1 shows the state at this time.

Then, the film 6 in the light-shielding container 4 is taken out from the light-shielding container 4 by a suction cup or the like and conveyed to a predetermined recording section.

By the way, in such a film package 2, the adhesive part 7 of the light-shielding container 4 and the adhesive part 9 of the cover member 8 are uniformly separated in the vicinity of the edge part 4b of the light-shielding container 4, perpendicular to the peeling direction shown by the arrow. They are uniformly bonded by width bonding portions 7a and 9a. Therefore, when this cover member 8 is peeled off in the image output laser printer device, the peeling force is evenly distributed over the entire surface of the adhesive portions 7a, 9a, so that a load is applied per unit area of the adhesive portions 7a, 9a. The tensile force becomes extremely small. Therefore,
A considerable force is required to peel the cover member 8 from the light-shielding container 4. Moreover, the edge portion 8 of this cover member 8
When peeling occurs each time a is pulled, the load is concentrated on the edge 4b side of the light-shielding container 4, and for example, the edge 4[) side of the film package 2 may be lifted up within the device. As a result, it becomes impossible to smoothly peel off the cover member 8.

The present invention has been made in order to overcome all the above-mentioned disadvantages, and the present invention has been made in order to overcome all of the above-mentioned disadvantages. To provide a sheet filler cage, a sheet filler cage, and a cage 7 which facilitates the peeling work of a light shielding member by being configured so that the peeling force is concentrated at at least one point, and which can reliably open the opening 1-1 part. With the goal.

In order to achieve the above object, the present invention provides a light shielding member that holds the sheet film 1 in a light-tight manner in an opening of a light shielding container in which several sheets of sheet film are laminated and stored in a removable state. In the sheet film package adhered to the sheet film package, the light-shielding container and the light-shielding member are configured to be bonded to each other so that, when the light-shielding member is peeled off from the light-shielding container, the peeling force is concentrated at one point at least at the beginning of peeling. shall be.

Next, preferred embodiments of the sheet film package according to the present invention will be described in detail with reference to the accompanying drawings.

In FIG. 2, reference numeral 10 indicates a film package according to the present invention, and this film package 10 includes a light-shielding container 14 for storing a sheet-like film 12, and an opening 14a of this light-shielding container 14 that is covered with the film. 12
It basically consists of a removable light shielding cover member 18 that keeps the light tight.

The light-shielding container 14 is a rectangular housing having an opening 14a, and a bonding portion 20 for bonding the cover member 18 is formed at the periphery of the opening 14a, as shown by diagonal lines. In this case, inside the adhesive part 20, the light-shielding container 14
At the end edge portion 141], the adhesive portion 20a is formed so as to be oriented in a direction perpendicular to the longitudinal direction of the light-shielding container 14 and gradually become narrower. Note that the edge portion 1 of the light-shielding container 14
The side surface 14c on the side 4b has protrusions 22a on both ends thereof,
22b is formed, and a handle portion 24 is formed on the side surface portion 14d opposite to the side surface portion 14c.

On the other hand, the cover member 18 includes the side surface 14c of the light-shielding container 14,
It is configured with a rectangular bendable light shielding member formed to be slightly longer than twice the distance between 14d and 14d. The cover member 18 holds the film 12 light-tight by having an adhesive portion 26 removably adhered to the adhesive portion 20 of the light-shielding container 14, as shown by the two-dotted chain line in FIG. In this case, the cover member 18 has one end connected to the light-shielding container 14.
The intermediate portion is adhered to the adhesive portion 20a at the end edge portion 14b. Furthermore, the area from this intermediate portion to the other end edge portion 18a is left unadhered.

The sheet film package of the non-implemented type A (J basic fishing) is constructed as described above, and its operation and effects will be explained next.

Here, FIGS. 3 and 4 show the film package 10.
This figure shows a loading section 30 of the image recording apparatus into which the image recording apparatus is loaded. Inside this loading section 30, a lid body 34 is provided on the main body section 32 side.
is rotatably supported via a hinge 36, and this lid body 3
4, the package loading port 38 is configured to be openable and closable. Further, a guide roller 40 is pivotally attached to the upper end of the lid 34 and is sandwiched between the lid 34 and the main body 32 when the package loading port 38 is closed. In this case, the lid body 34 is such that the opening 14a of the film package 10 is connected to the main body 32 when the package loading port 38 is closed.
It is arranged so that it is oriented diagonally upward.

On the other hand, on the main body 32 side, a suction cup 44 constituting a single-fed mechanism is configured to enter into the opening 14a of the film package 10 via a shutter member 42. in this case,
The shutter member 42 can be pulled out to the outside of the loading section 30, and the fully drawn state is detected by a limit switch 46 provided on the main body section 32 side. In addition,
The lid body 34 has protrusions 22a, 22 of the film package 10 loaded when the package loading port 38 is closed.
A retaining portion 48 into which b is fitted is formed.

Therefore, as shown by the two-dot chain line in FIG.
As shown in FIG.
It is installed in an inclined state on the lid body 34 of. At this time, the projections 22a and 22 provided on the side surface 14C of the light-shielding container 14
b is fitted into the engaging portion 48, and the film package 10 is fixed. Here, the cover member 18 of the film package 10 is bent at the end edge 14b of the light-shielding container 14 located below the loading section 30, and the end edge 18a of the cover member 18 is bent at the upper end of the lid 34. The guide 10 is positioned so as to protrude outward through the guide 40 which is pivotally connected to the guide 10.

Next, the package loading port 38 is closed by rotating the lid body 34 about the hinge 36 in the direction of 8 (clockwise). At this time, the end edge 18a side of the cover member 18 is It is sandwiched between the loading section 32 and a portion thereof is exposed to the outside of the loading section 30.

After the film package 10 has been loaded in this way, the cover member 18 is pulled in the direction of the arrow shown in FIG. is peeled off from the film package IO. In this case, the tensile force for pulling out the cover member 18 is applied to the adhesive portion 20a at the edge portion 14b of the light-shielding container 14 via the guide roller 40.

Here, as shown in FIG. 2, the adhesive portion 20a is formed to be inclined with respect to a direction perpendicular to the direction in which the cover member 18 is peeled off. Therefore, the peeling force is initially concentrated at one point of the adhesive portion 20a that is inclined, and the cover member 18 is gradually peeled off from one end side of the edge portion 14b of the light-shielding container 14 toward the other end side. That is, the tensile force for peeling off the cover member 18 is sufficiently concentrated on a portion of the bonded portion 20a. As a result, the cover member 18 can be peeled off without requiring any significant tensile force. Next, the cover member 1 after being peeled off from the adhesive portion 20a
If 8 is pulled further, the peeling operation will be more easily accomplished.

After the opening 14a is opened in this manner, the shutter member 42 is pulled out from the loading section 30, and the opening 14a is opened into the image recording apparatus.

Here, whether or not the opening 14a is reliably opened into the image recording apparatus is detected by a limit switch 46 that a part of the shutter member 42 comes into contact with.

Next, the film 12 housed in the film package 10 is moved to a suction cup 4 constituting a single-fed mechanism facing the opening 16.
4 and transported to a predetermined recording section.

Incidentally, in such a film package 10, the shape of the edge portion 14b of the light-shielding container 14 can be selected from various shapes.

This alternative embodiment is shown in FIG. That is, the edge portion 5 of the light-shielding container 14 to which the intermediate portion of the cover member 18 is adhered
0 in the same shape as the adhesive portion 20a, it becomes extremely easy to apply adhesive to the adhesive portion 20a of the edge portion 50 of the light-shielding container 14, for example.

Further, the shape of the adhesive portion 20a according to still another embodiment is shown in FIGS. 6 and 7.

That is, the adhesive portion 52 shown in FIG. 6 is the cover member I8.
It is formed so as to be inclined in a direction perpendicular to the peeling direction, and its width is configured to be substantially constant.

Also in this case, since the peeling force of the cover member 18 initially acts on the tip end 52a, the peeling operation itself becomes extremely easy.

The bonded portion 54 shown in FIG. 7 is formed to be inclined toward both sides from the central portion 54a of the tip of the edge portion 14b, and the cover member 18 extends from the center of this bonded portion 54 to both sides. Peels off evenly.

Therefore, there is no possibility that a component force in the lateral direction with respect to the peeling direction of the cover member 18 will occur, and the cover part 418 can be accurately peeled off along the peeling direction.
This has the effect of making the peeling work easier.

As described above, according to the present invention, the joint portion between the light-shielding container that stores the sheet film and the light-shielding member that covers the opening [1] of the light-shielding container is inclined with respect to the direction perpendicular to the peeling direction of the light-shielding member. It is configured to do so. Therefore, when the light-shielding member is peeled off from the light-shielding container, the tensile force is concentrated on a part of the bonded portion, and the light-shielding member can be peeled off very easily with less tensile force.

Moreover, since there is no need to take measures such as reducing the bonding force at the bonding portion, a sheet film package can be obtained in which the light-shielding properties of the sheet film stored in the light-shielding container are not degraded in any way before opening.

Although the present invention has been described above with reference to preferred embodiments, the present invention is not limited to these embodiments.
Of course, various improvements and changes in design are possible without departing from the gist of the present invention.
