A flexible cover member that shields a sheet film take-out opening constituting a package from light; a sheet film loading device and a sheet configured to easily load a sheet film in a bright room that can be peeled from the package; This invention relates to a film package.

Generally, radiographic images of a subject such as a human body using X-rays are used for medical diagnosis.
Conventionally, in order to record such radiographic images,
An X-ray film is loaded into a radiography device in a light-shielded state, and the emulsion surface of the film is directly irradiated with X-rays.

Incidentally, recently, a radiation image recording and reproducing system for obtaining a radiographic image of a subject using a storage phosphor (stimulable phosphor) has been developed, and it is becoming widespread, especially in the medical field as mentioned above. . here,
A storage fluorophore is a material that emits radiation (X-rays, α-rays, β-rays,
When irradiated with γ-rays, electron beams, ultraviolet rays, etc., a part of this radiation energy is accumulated, and when it is later irradiated with excitation light such as visible light, it emits stimulated luminescence according to the accumulated energy. means.

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 obtained stimulated luminescence light is read out photoelectrically to obtain an image signal, and based on this image signal, a recording material such as a photographic light-sensitive material, This is to output it as a visible image on a CRT or the like.

Here, when recording a visible image on a recording material, an image recording device, such as an image output laser printer device, is employed. This device stores photographic film, which is a recording material, through a magazine etc.
After this film is taken out one by one using a sheet-fed mechanism such as a suction cup, a predetermined image is recorded by irradiating the film with laser light based on the electrical signal obtained from the stimulable phosphor sheet. be. The film is then conveyed into an automatic developing device, passes through a developing process, and is then accumulated at a predetermined location.

In the image output laser printer device, like the conventional X-ray imaging device described above, when loading the film into the device, the film must not be exposed to external light, but in order to improve workability, normal There has been a strong desire to load film in a bright room, and various bright room loading systems have been considered. An example of this bright room loading method is disclosed in Japanese Utility Model Application Publication No. 56-5141.

That is, FIG. 1a shows a cross-sectional view of the film package 2 to be supplied to an X-ray imaging device, etc.
The film package 2 includes a light-shielding container 6 which is a housing having an opening 4, and a plurality of unexposed films 10 are housed in the light-shielding container 6 while being protected by a padded cardboard 8. ing. Further, a flexible light shielding member 12 is adhered to the opening 4 in a light-tight manner to protect the unexposed film 10 from external light. In this case, one end of the flexible light shielding member 12 is curved in the vertical direction, and a locking hole 12a is bored in the one end edge.

The film packaging body 2 constructed in this way has a first
It is stored in the magazine 14 shown in FIG. b and positioned by the storage section 16. Here, the magazine 14 is provided with a shutter member 18, and a locking protrusion 20 is implanted at the end of the shutter member 18.
After the magazine 14 is fitted into the hole 12a of the flexible light shielding member 12, the magazine 14 is loaded into an X-ray imaging device (not shown) or the like. Next, the other end of the shutter member 18 is pulled out from the magazine 14 by manual operation. As a result, the flexible light-shielding member 12 is peeled off from the light-shielding container 6 by the locking protrusion 20 that is engaged with the hole 12a, and the opening 4 is opened in the X-ray imaging apparatus. Thereafter, the unexposed film 10 is sucked by the vacuum suction device 22 and transported to a predetermined photographing position.

However, in the prior art as described above, a dedicated magazine must be used to store the film package. This dedicated magazine must be manufactured strongly so that it can withstand repeated attachment and detachment, and therefore the dedicated magazine itself has a considerable weight. Therefore, there arises a drawback that the work of attaching and detaching this special magazine is troublesome for the operator. Moreover, since the dedicated magazine is equipped with a shutter mechanism, etc., it has the disadvantage of being 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 in practice,
It has been pointed out that this is economically unacceptable.

Further, when the package 30 is displaced in the direction of the arrow, the tip of the package 30 comes into contact with the blade part 52. In this case, the lower surface portion 54b of the blade portion 52
The distance between and the base surface 47 is the height H ₁ of the tray stand 32
Therefore, when the package 30 is inserted in the direction of the arrow, the cutting edge 56 enters between the tip 34a of the cover member 34 and the inclined surface 39, and the cover member 34 is inserted into the tray stand 32. (See Figure 5). Here, if the cover member 34 is made of a flexible material, this cover member 34
After being peeled off from the tray base 32, it can be bent and inserted into the passage 50. At that time, the opening 44 has the same width as the height _H2 of the package 30,
In addition, since this opening 44 extends a predetermined length into the image recording device 40, when the cover member 34 is peeled off from the tray stand 32, light from the outside will pass through the opening of this tray stand 32. There is no possibility of intrusion into the 38.

When the package 30 is displaced in the direction of the arrow in this manner, its tip comes into contact with the locking surface 51, while the cover member 34 is introduced into the chamber 48 from the passage 50 and the package 30 is attached. The work is finished.
Here, since the locking surface 51 and the front portion 42 are separated by a distance H ₃ , it is possible to suitably position the opening 38 of the tray stand 32 with respect to the chamber 48 . In addition, the indoor cover member 34 is guided by the partition plate 58 and does not interfere with the suction cup 60 or the like. Therefore, the single-fed mechanism including the suction cup 60 is driven to transport the films A stacked and stored in the tray stand 32 one after another to a recording section (not shown).

When all the films A are dispensed, that is, the films A stored in the tray stand 32
After all the trays are removed, the tray stand 32 and the cover member 34 can be removed from the image recording device 40 as a unit by displacing the package 30 in a direction away from the image recording device 40.

Furthermore, the used packaging body 30 can be disposed of, especially if the tray stand 32 is made of an inexpensive resin material, cardboard, or the like. Moreover, when using various films of different sizes, even if packaging bodies corresponding to the films of each size are prepared, the cost will not increase to any significant extent. In addition, when using various films in this way, record the film type, film size, film lot number, etc. on each package in advance with a bar code, magnetic tape, etc.
If the information is read and displayed by a reading means provided in the image recording device when the package is attached to the image recording device, it is convenient to obtain the information necessary for image recording when using the image recording device. .

By the way, in this embodiment, a blade is fixed inside the image recording device in order to peel off the cover member, but an acute-angled edge that replaces the blade is integrally formed inside the image recording device. You may also use the This will be described below as a second embodiment. Components that are the same as those shown in FIG. 4 are designated with a suffix a, and their explanations will be omitted.

That is, as shown in FIG.
The width in the height direction of the second opening 62 is formed to be the same as the height _H1 of the tray stand 32, and the upper surface part 62a defining the second opening 62 has an acute cutting edge at the boundary with the passage 50a. A portion 64 is formed.

In such a configuration, the image recording device 40a
It will be readily understood that the process of loading and unloading the package 30 into and out of the image recording device 40 is performed in the same manner as in the image recording device 40 described above.

In the embodiment described above, the opening 38 is formed in a part of the upper surface 36 of the tray stand 32, but the entire upper surface 36 of the tray stand 32 is left as an opening, and the cover member 34 is peeled off. A portion of the opening may be opened to separate the film.

As described above, according to the present invention, a cover member is removably adhered to a tray stand for storing a plurality of films by closing the film take-out opening, and the cover member is peeled off into an image recording apparatus. A peeling means such as a blade is provided for this purpose. Therefore, when attaching the package to the image recording device,
The cover member can be automatically peeled off from the tray stand via this peeling means. Therefore, there is an advantage that film can be loaded extremely easily in a bright room. Furthermore, since the package is directly installed into the device, it can be manufactured at low cost without using a dedicated magazine like in the past, and it is also lightweight, making it easier to load the film. I can do it.

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