Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sheet film packaging body and a loading device, and more particularly, the present invention relates to a sheet film packaging body and a loading device, and more specifically, a packaging body containing a plurality of sheet films and having a film ejection opening closed with a cover member is inserted into the device. By inserting the cover member into a device and peeling it off while holding it between the holding means composed of the package and the device, the package is opened in a light-shielded device, and the film inside the package is sent out. The present invention relates to a sheet film packaging body and a loading device that enable this.

In general, radiation image films obtained by photographing objects such as human bodies using X-rays are widely used in medical diagnosis and the like. Conventionally, when taking radiographic images using such an X-ray film, the X-ray film is loaded into a radiation imaging device in a light-shielded state, and the emulsion surface of this film is directly irradiated with X-rays. The image of the subject is recorded.

Incidentally, recently, a radiation image recording and reproducing system that uses a stimulable phosphor to obtain a radiation vA transmission 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 employed. This device stores X-ray 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. 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 then is stored at a predetermined location and used for medical diagnosis, etc., if necessary.

By the way, in the image output laser printer device, when loading the X-ray film into the device, as in the conventional X-ray imaging device described above, the film must not be irradiated with external light, otherwise it will be exposed. It is. Therefore, the film loading operation is generally performed in a darkroom, but the efficiency of the loading operation is naturally low. Therefore, in order to improve the workability mentioned above, it became strongly desired to load the film in a normal bright room, and the technical idea to make this possible was published, for example, in Utility Model No. 56-7931. Disclosed.

That is, in relation to the prior art, FIG. 1a shows a cross-sectional view of a magazine 2 loaded into an X-ray imaging apparatus, etc., and this magazine 2 has a main body 4 and a butterfly that can be opened and closed. A chamber 8 is defined by the main body 4 and the lid 6. Holding rollers 10a and 10b are rotatably supported on the main body portion 4 and the lid portion 6, respectively, and are designed to prevent external light from being irradiated into the chamber 8 from the side of the holding rollers 10a and 10b. A light shielding member 12 is provided on the main body portion 4 and the lid portion 6. Further, a film ejection opening 14 is formed in the lid body 6, and a bendable handle 18 is formed at one end of a shutter member 16 provided in the lid body 6 for opening and closing the opening 14. ing.

A film package 20 is stored within this magazine 2. A plurality of unexposed films 24 are stored in the film package 20 while being protected by a cardboard 22, and both ends 20a and 20b of the film package 20 are exposed from the magazine 2 to the outside. It's exposed.

In such a configuration, first, the film packaging body 20
One end 20a is engaged with the handle 18 of the shutter member 16, and the other end 20b is cut with scissors or the like. Then,
As shown in FIG.
The shutter member 16 is pulled out from the magazine 2 by manual operation. As a result, the film package 20 is attached to the handle 18 and pulled out from the magazine 2, and since the film package 20 is held between the pinching rollers lQa and 10b, the film package 20 is held inside the film package 20. unexposed film 24 is fed into chamber 8. Furthermore, in this case, the chamber 8 in the magazine 2 is opened into the device 26 via the opening 14 . Therefore,
The unexposed film 24 is sucked by a vacuum suction device 28 and conveyed to a predetermined photographing 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 attached to and removed from 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, clamping rollers, etc., this dedicated magazine inevitably 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.

Furthermore, in order to load the film into the apparatus, after storing the film package in the magazine, one end of the film package is cut off, and the other end is hooked to a shutter member. , it is necessary to attach the magazine to the device and pull out the shutter member. 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 package that houses a plurality of films and is equipped with a flexible cover member that closes the film ejection opening. Then, the cover member is clamped via a clamping means constituted by the package and the device, and the package is opened in the device by pulling the cover member while ensuring a suitable light-shielding effect. This structure eliminates the need for the dedicated magazine used in the past, and makes it possible to load film in a bright room with a simple structure and in a light-dense condition, as well as to produce a lightweight and inexpensive sheet film. The object of the present invention is to provide a packaging body and a loading device for

In order to achieve the above object, the present invention provides a tray stand for storing a plurality of stacked sheet films, and a flexible cover member that is removably attached to the tray stand and closes an opening for taking out the film. an engaging portion is formed at one end of the tray base to cooperate with a light shielding means installed in the image recording device when the tray base is loaded, and the cover member is attached to the tray base. The length of the cover member is selected such that the other end thereof is bent and the end of the cover member extends outward from the end of the engaging portion. do.

Furthermore, the present invention closes the film take-out opening to form an opening into which the film packaging body is inserted, which engages the cover member and has an engaging portion that bulges outward at one end. A roller is disposed in the vicinity of the opening to press against the engaging portion and clamp the cover member, and further an opening/closing member is provided for opening and closing the opening and guiding an end of the cover member to the outside. It is characterized by being configured with:

On the other hand, the upper part 38 has an opening 4 for taking out the film.
0, and a locking part 42 that enters the opening 40 from one side of the upper part 38 is provided, and the upper part 3
8 bulges outward from the other side to form an engaging portion 44 .

In this case, the engaging portion 44 is directed toward the outside of the tray stand 32 along the opening 40 and is inclined upward at a predetermined angle. The distal end portion 44a of the engaging portion 44 is formed into a substantially cylindrical shape, and the engaging portion 44 is provided with an opening 46 having a predetermined shape so that the operator can grasp it with his or her fingers.

Then, the cover member 34 is fixed to the upper part 38 of the tray stand 32. The cover member 34 is formed to be more than twice as long as the length in the longitudinal direction of the tray stand 32, and the cover member 34 is arranged so that one end thereof is aligned with the engaging portion 44 side.
4 is fixed to the upper surface of the upper part 38 with an adhesive or the like. At this time, the cover member 34 completely closes the opening 40 and the upper part 3
8 is folded back and carried on the engaging portion 44, and the distal end portion 34a protrudes outward by a predetermined length from the distal end portion 44a of the engaging portion 44.

The sheet film package 30 is basically constructed as described above. Next, a loading device for loading this package 30 will be explained.

In FIGS. 3 and 4, reference numeral 50 indicates a loading device, for example, an image recording device, according to the present invention, and the image recording device 50 is provided with a package loading mechanism 52. In this case, the package loading mechanism 52 includes a package receiving section 54, a roller section 56, and a loading port opening/closing section 5.

The pedestal 60 constituting the package receiving section 54 is inclined at a predetermined angle with respect to the vertical direction, and is bent in accordance with the shape of the package 30. In FIG. 4, a stopper member 62 for pressing and fixing the upper part 38 of the package 30 is provided at the lower end of the pedestal 60. The stop member 62 has a trapezoidal locking portion 63 and the locking portion 63.
and a rod portion 64 integrally formed with the rod portion 64, and a coil spring 66 is externally mounted on the rod portion 64.

On the other hand, a roller 68 constituting the roller section 56 enters the package loading opening 69 and is rotatably supported by the device 50. In this case, the roller 68 and the engaging portion 44 of the package 30 sandwich the cover member 34 and achieve a shielding function of blocking the incidence of external light.

Furthermore, an opening/closing member 70 constituting the loading port opening/closing section 58
has a bent cross-sectional shape, and one end thereof is connected to the device ll! through a support bar 72. 50 so that it can swing freely. Holes 75a and 76b are formed in both end edges of one surface 74 of the opening/closing member 70, respectively, and locking members 78a and 78b are fitted into the holes 75a and 76b (see FIG. 5).

The locking members 78a, 78b have inclined surfaces 80a, 80b.
Locking parts 82a, 82b and pressing parts 84a, 84b provided with
Flange portions 85a and 86b are provided at one end of the pressing portion 84a184b. And the hole 76a
, 76b, and the locking members 73a, 78b are inserted into the hole 7.
5a and 76b, and further, the plates 90a and 90b are fixed to the surface portion 74, and the locking members 78a and 78b are engaged with the opening/closing member 70. In this case, the groove portion 91 defined by the surface portion 74 and the plates 90a and 90b is for inserting the cover member 34, and therefore, the groove portion 91 is formed so as to correspond to the width and thickness of the cover member 34. It is desirable to select the dimensions of the plates 90a, 90b. Note that it is preferable that the opening/closing member 70 is provided with a handle 93.

On the other hand, lock members 78a and 78 are provided on the image recording device 50 side.
Inclined surfaces 92a, 9 that engage with the locking portions 82a, 82b of b.
Engaging portions 94a and 94b are provided.

Further, the device 50 is provided with a shutter member 95, and a bent thin plate-shaped shutter 96 is engaged with the tip of the shutter member 95.

Further, the apparatus 50 is equipped with a suction mechanism 98 and a transport mechanism (not shown) for transporting the supplied sheet film F to the next stage image recording section.

The sheet film packaging body and loading device of this embodiment are basically constructed as described above, and the functions and effects thereof will be explained next.

Therefore, the work that loads the package 30 into the package loading mechanism 52 will be explained.

First, the opening/closing member 70 is swung to open the loading port 69 to the outside. That is, as shown in FIG.
The pressing parts 84a, 84b of the locking members 73a, 78b provided on both sides of the hole 76a, 7 are pressed by the operator's fingers.
6b, the locking parts 82a, 82b engage the engaging part 9.
The engagement relationship with 4a and 94b is released. Therefore, by swinging the opening/closing member 70 in the direction of arrow A via the handle 93, the loading port 69 is opened to the outside.

Next, the operator inserts the package 30 into the package receiving part 54 from the loading port 69 while holding the package 30 through the opening 46 formed in the engagement part 44 . At this time, the tip of the upper part 38 of the package 30 displaces the locking part 63 of the stopper member 62 in the direction of the arrow against the elastic force of the coil spring 66, so that the package 30 is stored in the pedestal 60. At this point, the stopper member 62 acts to press the upper part 38 due to the elastic force of the coil spring 66.

When the package 30 is stored in the pedestal 60 in this manner, the cover member 34 attached to the package 30 is held between the engaging portion 44 and the roller 68.

That is, the engaging portion 44 is inclined upward at a predetermined angle from the upper portion 38, and its tip portion 44a is pressed against the roller 68. In this case, the engaging portion 44 is made of a resin-based material having a predetermined elasticity, and therefore, the cover member 34 is held elastically between the distal end 44a of the engaging portion 44 and the roller 68 without any gaps. Ru.

Furthermore, when the opening/closing member 70 is swung in the direction of arrow B, the inclined surfaces 80a, 80b of the locking portions 82a, 82b are moved to the engaging portion 94.
The locking members 78a, 78b are in contact with the inclined surfaces 92a, 92b of the coil springs 88a, 94b.
It enters into the holes 76a and 76b against the elastic force of. Then, when the locking portions 82a, 82b are separated from the engaging portions 94a, 94b, the locking portions 82a, 82b are moved to the hole portions 76a, 82b by the elastic force of the coil springs 88a, 88b.
76b, and as a result, the opening/closing member 70 is fixed to the loading device 50 and closes the loading port 69. that time,
The tip 34a of the cover member 34 is led out to the outside through a groove 91 formed in the opening/closing member 70.

Therefore, by grasping the tip end 34a of the cover member 34 and pulling it out in the direction of arrow C, the cover member 34 is held at the top of the tray stand 32 while being held between the tip end 44a of the engaging portion 44 and the roller 68. It is peeled off from 38. in this case,
Since the distal end portion 44a of the engaging portion 44 is formed in a substantially cylindrical shape, there is little friction with the cover member 34.
can be pulled out smoothly. Also, tray stand 3
Since the tip of the upper part 38 of 2 is pressed by the stopper member 62, the tray stand 32 does not move during the peeling operation of the cover member 34 (for this reason, the cover member 34 can be peeled off even better). It will be held in

Further, the cover member 34 is attached to the tray stand 3 over a predetermined length.
2 and then pull out the shutter member 95 in the direction of arrow C, the shutter 96 is displaced in the direction of arrow C and the opening 4° of the tray stand 32 is opened to the image recording device 50.
Develop within. Next, the suction mechanism 98 is driven to sequentially pick up the sheet films F stored in the tray stand 32.
After being fed to a transport mechanism (not shown), an image is recorded on this film F. In addition, since the tray stand 32 is provided with the locking part 42, the sheet film F in the tray stand 32 will not fall into the apparatus 50.

In the above manner, the sheet film F in the tray stand 32 is
When all the trays are taken out, the suction mechanism 98 takes out the tray stand 3.
2, the recess 39 is engaged with the recess 39 provided on the bottom surface of the
Since external air flows into the suction mechanism 98 through the suction mechanism 98, it is detected that no sheet film F remains within the package 30. Then, the drive of the suction mechanism 98 is stopped, and as described above, the opening/closing member 70 is swung in the direction of arrow A to take out the empty package 30 from the package loading mechanism 52. Next, if necessary, a new package 30 containing a predetermined number of sheet films F is added to the package loading machine I.
In the case where the sheet film F is sequentially sent to the image recording section after being loaded into the I52, the sheet film packaging body 3 is used in this embodiment.
0 is directly loaded into the package loading mechanism 52, and the sheet film F is configured to be able to be sent out within the image recording section 250. That is, the sheet film F can be loaded by simply inserting the relatively lightweight package 30 into the package loading mechanism 52 without using a dedicated magazine as in the prior art. Moreover, the loading operation of the sheet film F essentially consists of an opening/closing process of the opening/closing member 70, an insertion process of the packaging body 30, and a peeling process of the cover member attached to the packaging body 30. This simplifies the previously complicated work and allows extremely efficient loading of the sheet film F. Furthermore, tray stand 3
By sandwiching the cover member 34 between the engaging portion 44 formed in the sheet film F 2 and the roller 68 provided in the package loading mechanism 52, the peeling operation of the cover member 34 is performed well, and external light is removed from the sheet film F. It prevents irradiation. Note that since the gripping opening 46 is formed in the engaging portion 44, the package 30 can be transported even more easily. The package 30 is lightweight and has considerable strength.

By the way, in this embodiment g, the engaging part 44 is inclined upward from the upper part 38, but the engaging part 44 is extended outward along the upper part 38, and on the other hand, for example, the elasticity of a coil spring is It will be easily understood that even if the roller 68 is configured to be pressed against the engaging portion 44 through force, the same effect as in the embodiment 1 can be achieved. Further, although the distal end 44a of the engaging portion 44 is formed in a cylindrical shape, if at least the opening 40 side (the side that the roller 68 contacts) of the distal end 44a is formed in a curved shape, the distal end 44a
may be integrally formed with the engaging portion 44 in a plate shape. Furthermore, it goes without saying that the tray stand 32 can be made not only of resin-based materials but also of cardboard or the like as long as it has a predetermined hardness.

As described above, according to the present invention, the engaging portion that bulges outward is formed on the tray base constituting the film package, and on the other hand,
A roller that slides into contact with the engaging portion is disposed on the loading device side,
The light-shielding cover member is held between the engaging portion and the roller to facilitate the peeling operation of the cover member, and to suitably prevent external light from entering the light-shielding cover member. Therefore, the package itself can serve as the magazine without using a dedicated magazine that is quite expensive and heavy as in the past. Moreover,
Film loading work in a bright room has become extremely simple.
Advantages such as being able to efficiently perform the film loading operation can be obtained.

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.
