Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sheet film package, and more particularly, a light-shielding cover member for closing a film take-out opening is attached to a tray stand for storing a plurality of sheet films;
The present invention relates to a sheet film packaging body that enables sheet film loading work in a light room in which the cover member is separated from the tray stand to define a sheet film takeout opening in a light-shielded device.

2. Description of the Related Art Generally, a radiographic image film obtained by photographing a subject such as a human body using X-rays is used for medical diagnosis and the like. Conventionally, when taking a radiation image using such a radiation film, the film is loaded into a radiation imaging device in a light-shielded state, and the emulsion surface of the film is directly irradiated with X-rays to obtain an image of the subject. are recorded.

Incidentally, recently, a radiation image recording and reproducing system that uses a stimulable phosphor to obtain a radiation transmitted image of a subject has been developed and is becoming widespread. Here, a storage phosphor is a material that, when irradiated with radiation (X-rays, α-rays, β-rays, γ-rays, electron beams, ultraviolet rays, etc.), stores some of this radiation energy and later emits visible light, etc. 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 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, The image is output as a visible image on a CRT or the like.

Here, when recording an image on a recording material, an image recording device, for example, an image output laser printer device is used. 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 an electrical signal obtained from a stimulable phosphor sheet. The device is configured to irradiate the film with a laser beam based on the image and record a predetermined image. Therefore, the film on which the new image has been recorded is conveyed into an automatic developing device, undergoes a developing process, and is then stored at a predetermined location, where it is used for medical diagnosis, etc., as necessary.

In this case, in the image output laser printer device, similarly to the conventional radiation image capturing device described above, when loading the photographic film into the device, the film must be handled so as not to be irradiated with external light. This is because it will be exposed to light. Therefore, film loading work is generally performed in a darkroom, but the efficiency of the loading work naturally deteriorates. Therefore, in order to improve the workability, it has become strongly desirable to load the film in a normal bright room, and the technical idea to make this possible is, for example,
No. 6-7931.

That is, in relation to the prior art, FIG. 1a shows a cross-sectional view of a magazine 1 loaded into a radiographic imaging apparatus, etc., and this magazine 1 has a main body 2 and a main body 2 that can be opened and closed. It includes a lid part 3 which is hinged, and a chamber 4 is defined by the main body part 2 and the lid part 3. Holding rollers 5a and 5b are rotatably supported on the main body portion 2 and the lid portion 3, respectively, and the holding roller 5a.

A light shielding member 6 is provided on the main body portion 2 and the lid portion 3 so that external light is not irradiated into the chamber 4 from the side 5b. Further, an opening 7 for taking out a film is formed in the lid 3, and a bendable handle 9 is formed at one end of a shack member 8 provided in the lid 3 for opening and closing the opening 7. ing.

A film package 10 is stored within this magazine 1. Inside the film packaging body lo is a padded cardboard 1.
A plurality of unexposed films 1 protected by 1
2 is housed in the magazine 1, and both ends 10a and 10b of the film package 10 are exposed to the outside from the magazine 1.

In order to load the film package 10 configured as described above in a bright room, first, the one end 10a of the film package 10 must be attached to the handle 9 of the shutter member 8.
The other end 10b is cut with scissors or the like. Next, as shown in FIG. 1, the magazine 1 is loaded into the X-ray imaging device 13, and the shutter member 8 is pulled out from the magazine 1 by manual operation. the result,
The film package 1o is attached to the handle 9 and pulled out from the magazine 1, and since the film package 10 is held between the pinching rollers 5a and 5b, the unexposed film 12 in the film package lo is It ends up remaining in the chamber 4.

Furthermore, in this case, the chamber 4 in the magazine 1 is opened into the device 13 through the opening 7 opened by the operation of pulling out the shutter member 8. Therefore, the unexposed film 12
is attracted by the vacuum suction device 14 and transported to a predetermined photographing position.

Further, as another conventional technique, there is a device disclosed in Japanese Utility Model Application Publication No. 56-5141. That is, FIG. 2a shows a cross-sectional view of a film package 15 to be supplied to an X-ray imaging device, etc., and this film package 15 includes a light-shielding container 17 which is a housing having an opening 16. A plurality of unexposed films 19 are stored in the light-shielding container 17 while being protected by a cardboard 18. Further, a flexible light-shielding member 20 is adhered to the opening 16 in a light-tight manner to protect the unexposed film 19 from external light. In this case, one end of the flexible light-shielding member 20 is curved vertically upward, and a locking hole 20a is bored in this one end edge.

The film package 15 constructed in this way is positioned by a storage section 22 housed in a magazine 21 shown in FIG. Here, the magazine 21 is provided with a shutter member 23, and after the hole 20a of the flexible light shielding member 20 is engaged with the engagement protrusion 24 implanted at one end of the shutter member 23, , the magazine 21 is loaded into an X-ray imaging device or the like (not shown). Next, the shutter member 23
The other end is pulled out from the magazine 21 by hand or the like. As a result, the flexible light-shielding member 20 is peeled off from the light-shielding container 17 by the locking protrusion 24 that engages with the hole 20a, and the opening 16 is opened inside the X-ray imaging apparatus or the like. Then, the unexposed film 19 is sucked by the vacuum suction device 25 and conveyed to a predetermined imaging position.

However, in the prior art described above, a dedicated magazine must be used to store the film package.

Since this dedicated magazine is repeatedly loaded into the image recording apparatus, it needs to be manufactured strongly so that it can withstand long-term use, and as a result, 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 provided with a shutter mechanism and the like, it is inevitably 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.

Furthermore, in order to load the film into the device, it is necessary to engage the end of the film package or the light shielding member to the shutter member, load the magazine into the device, and then pull out the shutter member. It is said that As a result, the disadvantage is that the loading operation of such a film is complicated and takes a considerable amount of time.

The present invention has been made in order to overcome the above-mentioned disadvantages, and includes a removably flexible cover member fixed to a tray stand for storing a plurality of films in a stacked manner, and the cover member is attached to the tray stand. The length of the cover member is selected and configured so that the end portion of the cover member is bent at one end and exposed to the outside of the device when the tray stand is loaded into the device;
It has a simple structure in which an opening for taking out the film can be defined in the tray stand by pulling and peeling off the cover member from the tray stand with the tray stand loaded in the device in a bright room and shielded from light. An object of the present invention is to provide a lightweight and inexpensive sheet film packaging body that eliminates the need for a conventionally used dedicated magazine.

In order to achieve the above object, the present invention comprises a tray base for storing a plurality of sheet films in a stacked manner, and a flexible cover member that is removably fixed to the tray base and closes a film take-out opening. In the packaging body, the cover member is folded back at one end of the tray base and extends from the other end of the tray base so that it is exposed to the outside of the device when the packaging body is loaded into the device. It is characterized by selecting the

The cover member 34 is formed to be twice or more larger than the length of the tray stand 32 in the loading direction, and a part of the cover member 34 completely closes the film ejection opening 40, and the end portion of the cover member 34 is folded back at approximately the middle of the front surface portion 42 and extends further outward than the rear surface portion.

The sheet film package of this embodiment is basically constructed as described above. Next, an image recording apparatus into which the package 30 is loaded will be described.

4 and 5, reference numeral 54 indicates a main body of the image recording apparatus, and a package loading section 5 is attached to the main body 54.
6 is provided. One end of the lid 58 constituting the package loading section 56 is attached to the main body 54 via a support pin 60 so that it can be opened and closed, and a locking member 62 is provided at the other end of the lid 58. It is being In this case, the locking member 62 is configured to be able to be displaced by the elastic force of a spring (not shown), and this locking member 62 engages with the main body 54 to fix the lid 58 to the main body 54. Also,
A roller 6 is attached to a package loading opening 64 that is opened and closed by a lid 58.
6 is inserted, and the roller 66 can be displaced relative to the main body part 54 through the elastic force of a coil spring (not shown).

On the other hand, the pedestal 68 on which the package 30 is placed is inclined at a predetermined angle with respect to the vertical direction, and is bent in accordance with the shape of the package 30. A stopper member 70 is provided at the lower end of the pedestal 68 for pressing and fixing the front end surface 42 of the package 30. The stopper member 70 includes a trapezoidal locking portion 72 and a rond portion 74 integrally formed with the locking portion 72, and a coil spring 76 is mounted on the rond portion 74.

Further, a shutter member 78 is provided in the main body portion 54, and a sheet mechanism 80 is disposed in a chamber within the main body portion 54 that is opened and closed by the shutter member 78.

Therefore, the operation of loading the package 30 into this image recording apparatus will be explained.

As shown in FIG. 4, the lid 58 is swung in the direction of arrow C to open the package loading port 64 to the outside, and the package 30 is inserted into the pedestal 68 from the loading port 64.

At this time, the surface part 42 of the upper part 38 of the package 30 displaces the locking part 72 of the stopper member 70 in the direction of the arrow against the elastic force of the coil spring 76, and the package 30 moves onto the pedestal 68.
When the stopper member 70 is housed in the stopper member 70 , the stopper member 70 acts to press the surface portion 42 due to the elastic force of the coil spring 76 .

In this case, a plurality of sheet films F are stacked and stored in the package 30 in advance, and the film removal opening 40 is closed with the cover member 34, and the end of the cover member 34 is inserted into the package loading port. 64 (see Figure 4).

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 5).

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 fifth
As shown in the figure, the tip side of the tray stand 32 to which the cover member 34 is fixed with adhesive or the like tries to rise in the direction of arrow G. However, since the distal end surface portion 42 of the tray stand 32 is pressed toward the pedestal 68 side by the stopper member 70, the tray pedestal 32 is firmly fixed to the pedestal 68 and will not be displaced.

Eventually, the cover member 34 is reliably peeled off from the upper part 38 of the tray stand 32, and the film take-out opening 40 is opened sufficiently to allow the sheet film F to be taken out. Although the surface portion 42 of the tray stand 32 is formed into a single plate shape, due to the relationship with the stopper member 70, for example, as shown by the two-dot chain line in FIG. Of course, it may also be configured by

Further, after pulling out the shutter member 78 in the direction of the arrow E, if the sheet film mechanism 80 is driven, 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.

In this case, in this embodiment, in order to form the sawtooth-shaped step portion 48 on the inner surface of the surface portion 46 of the tray stand 32, the single wafer mechanism 80
Therefore, two sheets of film F are placed on the tray stand 3 at a time.
It cannot be removed from 2. That is, when the take-out operation is performed, the lower end of the sheet film F comes into contact with the stepped portion 48, that is, the protrusion, and vibrates. Therefore, even if a plurality of sheets of film F are taken out at the same time due to static electricity or the like, the sheet film F that is not directly attracted to the sheet feeding mechanism 80 is attracted, detached from the sheet film F that is in the process of being conveyed, and is placed inside the tray stand 32. It will be stored. Moreover, since the upper part 38 of the tray stand 32 is provided with a locking part 44 that protrudes into the film take-out opening 40, the sheet film F stored in the tray stand 32 can be attached to the tray stand 32.
It won't fall off.

In this way, under the driving action of the single-fed mechanism 80, the package 3
After all of the sheet film F in 0 is fed out, the sheet feeding mechanism 80 engages with the recess 52 formed on the lower inner surface of the tray stand 32, and the sheet film F is fed into the tray stand 32.
When it is detected that no wafer remains, the driving of the single wafer mechanism 80 is stopped. Here, the shutter member 78 is displaced in the direction opposite to the arrow E to close the inside of the main body 54, the lock member 62 is released and the lid body 58 is swung in the direction of the arrow C, and the empty package is 30 is removed from the package loading section 56. Next, if necessary, a predetermined number of sheet films F
The new package 30 containing the film can be placed on the pedestal 68, and the sheet film F can be loaded into the main body 54 according to the procedure described above.

In this case, in this embodiment, the package 30 is directly loaded into the apparatus main body 54 with the film removal opening 40 of the tray stand 32 closed with the cover member 34, and the lid 58 is
After closing the package loading port 64 through the opening 64, the end portion of the cover member 34 exposed to the outside is pulled to open the film removal opening 40 inside the apparatus main body 54. That is, since the packaging body 30 has the same effect as a magazine, the dedicated magazine used in the past becomes unnecessary, and the loading operation of the sheet film F becomes even simpler. Furthermore, the film removal opening 40 can be opened with the package 30 loaded in the apparatus main body 54 and the inside of the apparatus main body 54 suitably shielded from light by the roller 66 and the lid 58. The effect that loading work can be easily accomplished in a bright room is obtained.

Furthermore, one end portion of the cover member 34 that is folded back at the front surface portion 42 of the tray stand 32 and extends rearward is connected to the upper surface of the other end portion of the cover member 34 or the If it is releasably adhered to the upper part 38 of the tray stand 32, handling of the folded cover member 34 becomes extremely easy. That is, it is possible to avoid inconveniences such as the ends of the cover members 34 falling toward other packages 30 when the packages 30 are transported or when a plurality of packages 30 are stored in close proximity.

Note that in this embodiment, the cover member 34 is attached to the tray stand 32.
Although the cover member 34 is peeled off from the tray stand 32 in the loading direction, for example, the peeling direction of the cover member 34 may be selected to be perpendicular to the loading direction of the tray stand 32. That is, if the cover member 34 is peeled off in a direction perpendicular to the loading direction of the tray stand 32 (short direction), there is an advantage that the peeling operation can be easily performed.

Further, in this embodiment, the end portion of the recovery member 34 is bonded over substantially the entire surface of the upper portion 38 of the tray stand 32, but the tray stand 32 and the cover member 34 may be adhered to each other using other methods. I can do it. That is, a continuous protrusion is formed in the upper part 38 so as to surround the film removal opening 40, and the protrusion and the cover member 34 are welded together, for example. Therefore, the protrusion and the cover member 34 are integrally bonded to each other, so that the film take-out opening 40 is completely closed, and the operation of peeling off the cover member 34 is simplified.

Next, a sheet film package according to another embodiment of the present invention is shown in FIG.

Note that the same reference numerals are given the same reference numerals with the suffix "a" attached to the same components as in the first embodiment described above, and detailed explanation thereof will be omitted.

In this case, a protrusion 84 is provided on the tip end surface 46a of the lower portion 36a.
a and 84b are formed to bulge outward. Then, a flexible cover member 34a is removably adhered to the upper part 38a of the tray stand 32a, and a part of the cover member 34a completely covers the film ejection opening 40a, and the end of the cover member 34a A grip frame portion 86 having a predetermined width is formed by cutting out from both sides of the portion. Further, a hard guide member 88 is firmly fixed to the rear end side of the tray stand 32a so as to cover a part of the cover member 34a. At that time, the opening 40 is opened at the position where the cover member 34a is peeled off from the tray stand 32a and comes into contact with the guide member 88.
The mounting position of the guide member 88 is selected so that a is sufficiently opened.

The package 30a configured in this manner is loaded into a device configured in substantially the same manner as the device main body 54 shown in FIGS. 4 and 5, similarly to the first embodiment described above. In this case, in the device according to the second embodiment, holes (
4) is bored and the stopper member 70 is removed. That is, in this second embodiment, the protrusions 34a and 84b provided on the tray stand 32a and the hole in the pedestal 68 are used instead of the tip end surface portion 42 of the tray stand 32 and the stopper member 70 shown in the first embodiment. The tray stand 32a is configured not to be displaced when the cover member 34a is peeled off. Therefore, it is easily understood that the loading operation of the package 30a is performed in the same manner as the package 30 of the first embodiment described above.

Further, in this case, when the cover member 34a is peeled off from the tray stand 32a, it is confirmed that the cover member 34a engages with the guide member 88 and the film ejection opening 40a is opened in the apparatus. At this point, the sheet film loading operation is completed.

In this manner, in this embodiment, the cover member 34a is not completely peeled off from the tray stand 32a, so that a more light-tight light-shielding state is ensured between the apparatus main body and the cover member 34a. On the other hand, a narrow grip portion 86 is provided at the end of the cover member 34a.
, the operator can easily peel off the cover member 34a using the grip portion 86.

Furthermore, sheet film packages according to other embodiments of the present invention are shown in FIGS. 7 and 8.

Therefore, it is possible to obtain the effect that the second cover member 34e can be peeled off more easily than in the first to fourth embodiments.

As described above, according to the present invention, a flexible cover member is fixed to a tray stand for stacking and storing a plurality of sheet films by closing the film ejection opening, and this cover member is attached to the tip side of the tray stand. The length of the cover member is selected so that the cover member can be bent at the rear end side of the tray stand and further exposed to the outside of the apparatus. Therefore, with the tray stand loaded into the apparatus and the end of the cover member exposed to the outside, the inside of the apparatus is shielded from light, and the end of the cover member is pulled to open the film ejection opening in a light-tight manner. It can be opened in the device in the state. That is, this makes it possible to easily load the sheet film in a bright room, and also eliminates the need for a conventionally used magazine, thereby further simplifying the sheet film loading operation. Moreover, since the structure of the package is simple, there is an advantage that it can be manufactured at low cost.

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.
