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 an X-ray imaging device in a light-shielded state, and the emulsion side of this film is
X-rays are irradiated directly.

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, the storage phosphor means radiation 01
, α rays, β rays, γ rays, electron beams, ultraviolet rays, etc.), some of this radiation energy is accumulated, and later by irradiating excitation light such as visible light, a brightness corresponding to the accumulated energy is generated. A phosphor that exhibits exhaustion.

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 ff-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, It is output as a visible image on a CRT or the like.

Here, when recording a visible image on a recording material, an image recording device, for example, an image output laser printer device is employed. This device stores photographic film, which is a recording material, through a magazine, etc., takes out the film one by one using a sheet-fed mechanism such as a suction cup, and then converts it into electrical signals obtained from a stimulable phosphor sheet. Based on this, the film is irradiated with laser light to record a predetermined image. This 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 methods have been considered. An example of this bright room loading method is disclosed in Japanese Utility Model Application Publication No. 56-5141.

It is removably fixed to. Note that this cover member 34 is formed to have substantially the same dimensions as the upper surface portion 36. Further, the tip end 34a of the tray stand 32 facing the inclined surface 39 is curved slightly upwardly so as to move away from the inclined surface 39. It is configured to easily fit between the upper surface portion 36 and the cover member 34.

On the other hand, the front part 42 of the image recording device 40 to which the package 30 is attached, that is, the output laser printer device, has a width H2 in the height direction of the package 30, and a width H2 in the longitudinal direction of the package 30. A first opening 44 having a rectangular cross section and having the same size as the width of 3o is defined, and a second opening 46 having a predetermined height communicates with one end of the first opening 44. It is defined by In this case, the first opening 44 extends inward from the front surface part 42 by a predetermined distance, and the first opening 44 and the second opening 46 are formed at the same height, and are located at the base. It constitutes a surface 47. The boundary between the openings 44 and 46 is inclined at a predetermined angle with respect to the horizontal direction and is curved to form a chamber 48 in the image recording device 40.
A passage 5o that is open to the outside communicates with the outside. In addition, the base surface 4

In this case, the length of the blade portion 52 in the longitudinal direction has approximately the same dimension as the width of the package 30 (see FIG. 5). Further, the upper surface portion 54a and the lower surface portion 54b of the blade portion 52 are in a parallel relationship, and a cutting edge portion 56 is formed at one end of the lower surface portion 54b, inclined at a predetermined angle with respect to the upper surface portion 54a. In such a configuration, the cutting edge portion 56 faces the passage 50 having a cross-sectional shape substantially the same as the cross-sectional shape of the cover member 34, and the upper surface portion 54a of the blade portion 52 is placed on the upper surface portion 46a on the opening 46 side. For example, brazing is fixed by etc. At that time, the lower surface portion 54b of the blade portion 52 and the base surface 4
The dimensions of the blade portion 52 and the second opening portion 46 are selected so that the distance from the tray portion 7 is the same as the height Hl of the tray stand 32 including the cover member 34.

In addition, in order to improve the light shielding property when the package 30 is loaded on the wall surfaces around the first and second openings 44 and 46,
It is desirable that a raised material or the like be provided.

The sheet film loading device and sheet film package according to the present invention are basically constructed as described above, and the functions and effects thereof will be explained next.

First, the package 30 is inserted into the opening 44 of the image recording device 40 from the front end side where the opening 38 is provided.

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 541) of the blade portion 52 and the base surface 47
Since the distance between the two ends is equal to the height Hl of the tray stand 32, if the package 30 is inserted in the direction of the arrow, the cutting edge 56 will be located between the tip 34a of the cover member 34 and the inclined surface 39.
This cover member 34 is then peeled off from the tray stand 32 (see FIG. 5). Here, if the cover member 34 is made of a flexible material, the cover member 34 can be bent and inserted into the passage 50 after being peeled off from the tray stand 32. At this time, since the opening 44 has the same width as the height Hl of the package 30 and extends a predetermined length into the image recording device 40, the cover member 34 is When the tray is peeled off from the tray stand 32, no light from the outside enters into the opening 38 of the tray stand 32.

If the package 30 is displaced in the direction of the arrow in this way,
Its tip abuts against the locking surface 51, while the cover member 3
4 is introduced into the chamber 48 from the passage 50 and the package 30
The installation work is completed. Here, since the locking surface 51 and the front part 42 are separated by a distance H1, it is possible to suitably position the opening 38 of the tray stand 32 with respect to the chamber 48.

Further, the cover member 34 inside the chamber 48 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 in sheets, that is, after all the films A stored in the tray stand 32 are taken out, if the package 30 is displaced in the direction away from the image recording device w40, the above-mentioned The tray stand 32 and the cover member 34 can be removed integrally from the image recording device 40.

In addition, the used packaging body 30 is especially stored on the tray stand 3.
If 2 is made of an inexpensive resin material or cardboard,
It also becomes possible to dispose of it. Furthermore, 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 significantly. In addition, when using various films in this way, record the film type, film size, film loft number, etc. on each package in advance with a bar code, magnetic tape, etc., and record them on the image recording device. If the information is read and displayed by a reading means provided in the image recording device when the package is attached, it is convenient because the information necessary for image recording can be obtained when the package is used.

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. 6, the width in the height direction of the second opening portion 62 is formed to be the same as the height H of the tray stand 32,
A passage 5 is provided in the upper surface portion 62a defining the second opening portion 62.
An acute cutting edge 64 is formed at the boundary with 0a.

In such a configuration, it will be easily understood that the process of loading and unloading the package 30 into the image recording device 40a 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. The film may be deposited one by one by partially opening the opening.

As described above, according to the present invention, a cover member is removably adhered to a tray stand that stores a plurality of films by closing the film ejection 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 one tray through this peeling means. Therefore, there is an advantage that film can be loaded extremely easily in a bright room.

Furthermore, since the package is installed directly into the device,
It can be manufactured at low cost without using a dedicated magazine as in the past, and it is also lightweight, making it easier to load the film.

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.
