Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sheet film package, and more particularly, the present invention relates to a sheet film package, and more particularly, a light shielding member is removably attached to a tray stand for storing a plurality of sheet films by closing a film ejection opening. The present invention also relates to a film packaging body which is configured such that a hard outer cover is detachably provided on the tray stand to prevent damage to the light shielding member and can be used for various purposes.

2. Description of the Related Art Radiographic imaging apparatuses are commonly used that irradiate a subject such as a human body with radiation, record a radiographic image on an X-ray film, and use this for medical diagnosis. In this case, an X-ray film is loaded into the radiographic image capturing apparatus 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 radiographic image recording and reproducing system that obtains a radiographic image of a subject using a storage phosphor (stimulable phosphor) has been developed, and it has become widespread in the medical field as mentioned above. be.

Here, a storage phosphor is a material that, when irradiated with radiation (X-rays, α-rays, β-rays, T-rays, electron beams, ultraviolet rays, etc.), stores a portion of this radiation energy and later emits visible light, etc. A phosphor that generates stimulated luminescence according to the accumulated energy when irradiated with excitation light.

The above-mentioned radiation image recording and reproducing system utilizes this stimulable phosphor, and the radiation image information of the human body etc. is stored and recorded on a sheet having a layer made of the stimulable phosphor. The sheet is scanned with excitation light such as a laser beam to generate stimulated luminescent light, the resulting stimulated luminescent light is read photoelectrically to obtain an image signal, and based on this image signal, images are recorded 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 an image recording material, an image recording device, for example, an image output laser printer device is employed. This device stores a photosensitive film, which is an image recording material, through a film package, and takes out the film one by one using a sheet-fed mechanism including a suction cup.
The film is irradiated with a laser beam modulated based on an image signal obtained from a stimulable phosphor sheet, and the image accumulated and recorded on the sheet is exposed and recorded. Then, this film is transported into an automatic developing device and, after undergoing a developing process, is stored at a predetermined location or is directly provided for medical diagnosis or the like.

Incidentally, in the image recording device, as in the conventional radiation image capturing device described above, when loading the film into the device, the film must not be irradiated with external light.
This is because the film will be exposed. Therefore, when loading film into an image recording apparatus or the like, it is generally inconvenient that the film must be loaded in a dark room.

Therefore, in order to improve operability, it is strongly desired to load the film in a bright room, and various bright room loading methods have been proposed to make this possible. An example of this bright room loading method is disclosed in Japanese Utility Model Application Publication No. 56-5141. This is shown in FIG.

That is, FIG. 1a shows a cross-sectional view of a film package 2 to be supplied to an image recording apparatus, and this film package 2 includes a housing-like light-shielding container 6 having an opening 4. A plurality of unexposed films 10 are stored in the light-shielding container 6 while being protected by a cover 8. Further, a flexible light-shielding member 12 is attached to the light-shielding container 6 so as to close the opening 4 in a light-tight manner, thereby protecting the unexposed film 1O from external light. In this case, the flexible light shielding member 1
2 is curved upward in the vertical direction, and a locking hole 12a is bored in this one end.

The film package 2 constructed in this way is stored in the magazine 14 shown in FIG. 1, and positioned by the storage section 16. Here, the magazine 14 includes a shutter member 1.
8 is provided, and the hole 1 of the flexible light shielding member 12 is inserted into the locking protrusion 20 implanted at one end of the shutter member 18.
After the magazine 2a is engaged, the magazine 14 is loaded into an image recording device (not shown).Next, the other end of the shutter member 1 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 displacement of the locking protrusion 20 that engages with the hole 12a, and the opening 4 is opened in the image recording apparatus. Next, the unexposed film 10 is sucked through the opening 4 by the vacuum suction device 22 and transported to a predetermined photographing position.

However, in the prior art 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, a drawback arises in that it is troublesome for the operator to attach and detach the dedicated magazine. Moreover, since the dedicated magazine is equipped with a shutter mechanism, etc., it becomes quite expensive.Especially when using various films of different sizes, it is necessary to prepare a dedicated magazine corresponding to each size of film. However, it has been pointed out that the manufacturing cost increases significantly, which is economically unacceptable in practice.

Furthermore, in the prior art described above, a flexible light-shielding member for closing the opening of the film package is exposed to the outside. Therefore, when the film packages are transported or stacked in a predetermined storage position, other film packages often come into contact with the light shielding member. Since the light-shielding member is made of a relatively soft and flexible material, there is a risk that the light-shielding member will be damaged by the hard light-shielding container and the unexposed film will be exposed to external light. arise. In particular, it has been pointed out that a light-shielding container in the form of a housing has a disadvantage in that the light-shielding member and the film are easily damaged at the corners.

On the other hand, the light-shielding container into which all the unexposed film has been sent out within the image recording apparatus is generally discarded after being taken out from the image recording apparatus.

However, even if the light-shielding containers themselves are relatively inexpensive, as the frequency of use of the film increases, the number of used light-shielding containers increases, and if they are not used for other purposes, it becomes extremely uneconomical. The inconvenience of becoming a thing is exposed.

The present invention has been made in order to overcome the various disadvantages described above, and provides a tray stand for storing a plurality of sheet films in a stacked manner, and a peelable flexible structure for closing the film ejection opening of the tray. A light-shielding first cover member and a hard second cover member removably attached to the tray stand, and the tray stand itself is directly loaded into the apparatus and the first cover member is peeled off. to open a film ejection opening in the device, and when transporting or storing the package, a second cover member is attached to prevent damage to the first cover member due to external force, and further, The second cover member is attached to the tray stand after all the sheet film has been taken out, and used as a case for transporting or storing developed film, for example, thereby making it possible to replace the conventionally used dedicated magazine. To provide a sheet film packaging body that does not require the above and can be used for multiple purposes.

In order to achieve the above object, the present invention provides a tray stand for storing a plurality of sheet films in a stacked manner, and a thin film-like flexible light-shielding film that is removably fixed to the tray stand and closes a film ejection opening. The present invention is characterized in that it comprises a first cover member made of a material, and a second cover member made of a hard member that covers the first cover member and is removably attached to the tray stand.

Then, the lid body 58 is swung in the direction of the arrow to close the package loading port 64, and the lid body 58 is
is fixed to the main body portion 54. On the other hand, the cover member 34 is held between the roller 66 and the inner surface of the lid 58, and its end portion is led out to the outside through a gap 82 defined between the lid 58 and the main body 54. (See Figure 4).

Next, grasp the end of the cover member 34 and move it in the direction of arrow E.
When the cover member 34 is pulled in the direction shown in FIG. In this case, when the cover member 34 is pulled in the direction of arrow E, the tip side of the tray stand 32 to which the cover member 34 is fixed tries to rise in the direction of arrow G, as shown in FIG.

However, since the columns 46a and 46b of the tray stand 32 fit into the holes 70a and 70b of the pedestal 68, the tray pedestal 32 is firmly fixed to the pedestal 68 and is not displaced. Never.

As a result, the cover member 34 is reliably peeled off from the upper part 40 of the tray stand 32, and the film take-out opening 42 is opened sufficiently to allow the sheet film F to be taken out.

Further, after pulling out the shutter member 78 in the direction of the arrow E, if the sheet film mechanism 80 is swung, the plurality of sheet films F stored in the package 30 are transferred one by one to an image recording section (not shown). It will be transported by suction.
