Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sheet film package and a loading device, and more particularly, the present invention relates to a sheet film package and a loading device, and more particularly, a package that can be opened and closed and stores a large number of sheet films such as photographic materials is inserted into a casing. The present invention relates to a sheet film package and a loading device that enable the package to be opened within a light-shielded casing and the film inside the package to be delivered.

2. Description of the Related Art Generally, a method of recording an image of a subject such as a human body on a film using X-rays is widely used for medical diagnosis and the like. In this case, an X-ray film is loaded into an X-ray image capturing apparatus in a light-shielded state, and an image of the subject is recorded by directly irradiating the photosensitive emulsion surface of the film with X-rays.

Incidentally, in recent years, a radiation image recording and reproducing system that obtains a radiographic image of a subject using a storage phosphor (stimulable phosphor) has been developed and is rapidly becoming popular, especially in the medical field as mentioned above. . Here, the storage phosphor refers to radiation (X
rays, α rays, β rays, γ rays, electron beams, ultraviolet rays, etc.), some of this radiation energy is accumulated, and later when excitation light such as visible light is irradiated, the energy is A phosphor that emits photostimulable 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, in order to record an image on a recording material, an image recording device, for example, an image output laser printer device is employed. This device stores photosensitive sheet film, which is a recording material, through a magazine, etc., and takes out the film one by one using a sheet-fed mechanism that uses suction power, etc., and then extracts the film obtained from the stimulable phosphor sheet. A predetermined image is recorded by irradiating the film with laser light based on the electrical signal. The film on which the radiation image has been drawn using laser light is transported to an automatic developing device, where it is exposed to light through a developing process, and then accumulated at a predetermined location and used directly for medical diagnosis or for that diagnosis. It will be stored.

Incidentally, 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, it is necessary to There has been a strong desire to load film indoors, and various bright room loading methods have been proposed to make this possible. As an example, a package in which a sheet film is enclosed in a light-shielding bag is stored in a magazine, both ends of the light-shielding bag are exposed from the magazine, and one of the ends is cut off with a cutter or the like. There is something. In this case, the light-shielding bag is removed from the other uncut end side, and the film itself remains in the magazine.

However, when the light-shielding bag is removed from the magazine, there is a risk that light may enter through the opening of the light-shielding bag or the gap in the magazine and the film may be exposed to external light. Careful handling is required. In addition, a dedicated magazine is required, and it is necessary to prevent the magazine from being damaged when removing the light-shielding bag, and as a result, it is necessary to ensure the required strength of the magazine itself, so it is necessary to reduce the weight of the magazine and manufacture it. There are certain limits to cost reduction.

On the other hand, a cutting mechanism for cutting one end of the light-shielding bag and a light-shielding bag removal mechanism for taking out the film from the light-shielding bag after cutting are installed in the device, and a suitable film can be loaded by operating inside the light-tight device. Although it is conceivable to construct the device so as to obtain the state, in this case, the mechanism becomes extremely complicated and large-scale.

In addition, as another example, a light-shielding bag has been devised in which one end is opened in advance and simply folded, but in this case, the light-shielding bag is accidentally opened before the package is stored in the magazine. There is a risk that it will be damaged and cannot actually be used.

The present invention has been made to overcome the above-mentioned disadvantages, and after inserting an openable and closable box-shaped package containing a sheet film in a light-shielded state into a light-shielded casing, the By opening the body and making it possible to feed the film inside the package to the image recording unit, the package itself has the function of a magazine, eliminating the need for a dedicated magazine and eliminating the need for a dedicated magazine. The use of light-tight bags and special magazines is avoided, and as a result, problems such as light penetration when using light-tight bags and the complexity of the mechanism for opening the light-tight bags and taking out the film are eliminated. To provide a sheet film packaging body and a loading device which can easily and reliably load a film in a state in which the film is loaded, has a relatively simple structure, is lightweight, and is inexpensive.

In order to achieve the above object, the sheet film packaging body of the present invention connects a lower box member and a lower box member via a hinge portion so as to be openable and closable, and the inner side portions of the upper box member and the lower box member are connected to each other via a hinge portion. A light shielding member is disposed in the upper box member or the lower box member, an unexposed sheet film is stacked and stored in either the upper box member or the lower box member, the upper box member and the lower box member are fitted together, and the light shielding member It is characterized in that it is configured to prevent external light from entering the unexposed sheet film.

Furthermore, in the sheet film loading device of the present invention, an opening is provided in the casing for loading a sheet film package consisting of an upper box member and a lower box member in which sheet films are stacked and stored, and furthermore, the sheet film loading device is provided with an opening in the vicinity of the opening. a light shielding means for closing the casing; and an opening/closing means for engaging one end of the upper box member to open and close the upper box member when a package is inserted into the casing. It is characterized by:

Next, preferred embodiments of the sheet film package and loading device according to the present invention will be described in detail with reference to the accompanying drawings.

1 to 3, reference numeral 10 indicates a first example of a package for storing a sheet-like unexposed film, and this package 10 includes an upper box 12, a lower box I4, light shielding members 20 and 22. (See Figure 3).

The upper box 12 and the lower box 14 have the shape of a rectangular parallelepiped box with one side removed. Therefore, the package 10 as a whole is such that the upper box 12 and the lower box 14 close their respective inner spaces. It has a box-shaped shape that fits together. In this case, upper box 1
2 and the lower box 14 do not require particularly high rigidity,
It can be constructed from relatively inexpensive members, and is preferably constructed using cardboard or the like, for example. here,
In the package 10, the part indicated by reference numeral A is the front, the part indicated by reference numeral B is the back, and the parts indicated by reference numerals C and D are the sides. On the back side B, the upper box 12 and the lower box 14 are hinged together, so that the front side A can be opened wide, as shown in FIG. In this case, the hinge part on the back side B side can be selected from various options. The hinge portion can be configured as follows. Furthermore, as shown in FIG.
An engaging portion 16 is provided protrudingly on the end portion of the back surface B side of the side surface C,
An arc-shaped elongated hole 18 that allows this retaining portion 16 to slide in a fitted state is provided in the side surface C of the upper box 12, and a similar retaining portion and elongated hole are also provided on the side surface side. The hinge portion can also be configured by:

On the other hand, a light shielding member 20 shown in FIG. 1 is attached to the lower box 14 so as to surround the inner side surface of the lower box 14.

In this case, the front A, back B, and side C, D of the lower box 14
A gap is defined between the inner side surface portion of the light shielding member 20 and the side wall portion of the light shielding member 20. Further, as shown in FIG. 3, a light shielding member 22 having the same structure as the light shielding member 20 is attached to the inside of the upper box 12. The light shielding members 20 and 22 are made of a material such as vinyl, which has a light shielding and moisture-proofing function that blocks the transmission of light and prevents moisture from passing through. That is, the third
As shown in the figure, when the package 10 is closed, the end of the light shielding member 20 comes into close contact with the light shielding member 22, and the side wall of the light shielding member 22 fits into the gap between the lower box 14 and the light shielding member 20. . As a result, a film storage chamber 24 that is shielded from light and has a moisture-proof effect is defined inside the package 10, and
Sheet-like films (not shown) are stacked in this film storage chamber 24.

In addition, in order to prevent the package 10 from being accidentally opened and outside light entering before the film stored in the package 10 is actually used, the upper box 1 is closed on the front A side of the package 10.
2 and the lower box 14 are preferably attached using adhesive tape.

The sheet film package 10 is basically constructed as described above.Next, the package receiving mechanism into which the package 10 containing the film is loaded will be explained.

The package receiving mechanism 26 shown in FIGS. 4 and 5 includes a guide member 28, a discharge member 30, a light shielding means 32, and an opening/closing means 34. As shown in FIG. 6, the package receiving mechanism 26 is disposed inside an opening 38 formed in a casing 36 made of a light shielding member. Note that the casing 36 includes a suction device and a conveyance device (not shown) for conveying the supplied film to the next stage image recording device.
will be decorated.

The guide member 28 is a member for guiding and locking the package 10 at a predetermined position in the casing 36, and has a generally rectangular shape, and has a bottom part 42 having a notch 40 and a bottom part 42. Side wall portions 44 and 46 erected at two opposing end portions of the portion 42 and a cutout portion 40 of the bottom portion 42
The locking portions 48a to 4 formed at the edge portion on the open side side of the
Consists of 8d. The locking parts 48a to 48d are formed to be spaced apart from each other by a predetermined distance and to stand upright perpendicularly to the bottom surface part 42. The guide member 28 is tilted and fixed so that the portions provided with the locking portions 48a to 48d are positioned downward (see FIGS. 7a to 7d).

In this case, a suction device for feeding the films one by one is provided above the guide member 28.

The discharge member 30 includes a rod 50 and a locking plate 52 fixed to the rod 50. The rod 50 is connected to a discharge member driving device (not shown) and is disposed below the notch 40. In this case, the locking plate 52 is configured to slide along the notch 40 by the discharge member driving device.

The light blocking means 32 includes a light blocking plate 54.56, an arm 58.60 and a spring 62.64. The light shielding plate 54 has a substantially rectangular shape, and the long shaft 66 is fitted into the long end portion of the light shielding plate 54, and the long axis 66 is fitted into the relatively short end portion of the light shielding plate 54.
A short axis 68 is fixed parallel to 6. Both ends of the long shaft 66 are pivotally supported near the opening 38 of the casing 36 (see FIG. 6). Furthermore, a notch 70 is provided at one end of the arm 58.
is formed, and the short shaft 6 is engaged with this notch 70, and the arm 58 is disposed along the side wall 44.

Furthermore, the spring 62 is engaged with the other end of the arm 58, and one end of the spring 62 is fixed to a predetermined location within the casing 36. On the other hand, the light shielding plate 56 has the same configuration as the light shielding plate 54 and has a long axis 72 and a short axis 74. Furthermore, the arm 60 is configured similarly to the arm 58, and a notch 76 is defined at one end of the arm 60.

In this case, the light-shielding plate 56 is disposed in the opening 38 so as to be in close contact with the light-shielding plate 54 with the light-shielding plate 54 upside down and left and right reversed, and both ends of the long axis 72 are located at predetermined locations within the casing 36. It is pivoted on. The arm 60 is arranged along the side wall 46 with the arm 58 upside down, and the short shaft 74 engages with the notch 76 . Further, a spring 64 is attached to the other end of the arm 60, and one end of the spring 64 is fixed to a predetermined location within the casing 36. That is, in this case, the light shielding plate 54.5
When no force is acting on the light shielding plate 54.
56 is configured to always close the opening 38 in a light-tight state.

The opening/closing means 34 includes a shaft 78 and an opening/closing plate 80.82,
Recesses 79a and 79b are formed in the shaft 78 at a predetermined distance, and opening/closing plates 80 and 82 are fixed to the recesses 79a and 79b. The tip portions of the opening/closing plates 80 and 82 are bent to form claw portions 84 and 86. The opening/closing means 34 is arranged above the guide member 28. Both ends of the shaft 78 are pivotally supported at predetermined locations within the casing 36, and a rotational drive device (not shown) is connected to the shaft 78. In this case, the claw part 8
4 fits between the locking portions 48a and 48b of the guide member 28, and the claw portion 86 fits between the locking portions 48C and 148d.

The packaging body and loading device for film 1 to film according to the present invention are basically constructed as described above, and the functions and effects thereof will be explained next.

First, if the front A side of the package 10 containing the sheet film is attached with an adhesive tape, the adhesive tape is removed and the package 10 is fixed as shown in FIG. 7a.
is inserted into the casing 36 from the front A side through the opening 38. At that time, the light shielding plate 5 that was blocking the opening 38
4.56 is pushed toward the guide member 28 by the package 10, and as a result, the spring 62.64 (see FIG. 4)
As the arm 58.60 contracts, the arm 58.60 is displaced in its longitudinal direction, the light shielding plate 54.56 is opened, and the package 10 is inserted into the guide member 28 side. Then, the package 10 slides on the guide member 28, and the back side B of the package IO separates from the light shielding plate 54, 56, and as a result, the spring 62
．． 64, the light-shielding plates 54, 56 are closed, and the casing 36 becomes light-tight. Furthermore, the package 10 that has slid on the guide member 2B comes into contact with the locking portions 48a to 48d (see FIG. 5) and is locked (see FIG. 7). In this case, the claw portions 84 and 86 of the opening/closing means 34 are close to the lower part of the front A side of the upper box 12.

Therefore, the shaft 78 is rotated in the direction of arrow G by a rotation drive device (not shown). As a result, first, the claw portion 84.86
is locked on the front A side of the upper box 12, and then the front A side of the upper box 12 is lifted upward according to the arc-shaped displacement of the claw portions 84, 86 as the shaft 78 rotates in the direction of the arrow G. (See Figure 7C). That is, the package 10 is closed within the light-shielded casing 36 by such an operation of the opening/closing means 34.

Next, a suction bag M9 that constitutes a single-fed mechanism is used to send out the films one by one from the opening of the package 10 to the next device.
0 enters the lower box 14 side. By the operation of this suction device 90, the films in the package 10 are transported one by one through a transport path (not shown).

When the feeding of the film from the package 10 is completed, the suction device 90 is returned to its original position, and the shaft 78 is rotated in the direction of arrow H by the rotation drive device. The claw portions 84 and 86 that lock the upper box 12 with this
is rotationally displaced in the direction of arrow H, and finally the upper box 12 is replaced by the lower box 1.
4 and the package 10 is closed, resulting in a state similar to that shown in FIG.

Next, the ejection member 3 is moved by the ejection member driving device (not shown).
0 to the opening 38 side. This displacement causes the locking plate 52 to push the package 10 toward the third opening side. At that time, the back side B side of the package 10 presses the light shielding plates 54 and 56,
Accordingly, the springs 62, 64 (see FIG. 4) are expanded, the light shielding plates 54, 56 are opened, and the package 10 is discharged to the outside of the opening 38 (see FIG. 7C). That is, the ejecting member 30 and the ejecting member driving device correspond to ejecting means for ejecting the package 10 inserted into the casing 36. Then, by pulling out the package 10, the film loading operation is completed.

Note that when opening the package 10 as shown in FIG. The body 10 is connected to the locking parts 48a to 48d.
(Refer to Figure 4) The rotary drive device is configured to start the rotary drive device by detecting contact with the rotary drive device using a Mitsut switch or an optical switch, and using a detection signal from the switch. You can also do it. In this case, since the package 10 is automatically opened following insertion of the package 10 through the opening 38, the operation is even simpler and preferred. Further, by detecting the completion state of opening of the package 10 by the opening/closing means 34 using a limit switch or the like, and introducing the detection signal to the single-fed mechanism including the suction device 90, the package 10 can be opened. It will be readily appreciated that the film feeding process following opening could be automatically initiated.

Furthermore, after all the films in the package 10 are fed by the operation of the suction device 90, even if the suction device 90 operates, the film will not be supplied to the next device. Therefore, a sensor is provided on the film transport path to detect the passage of the film, and a signal from this sensor is used to detect the completion of film feeding, and by using the detection signal, the suction device 90 is returned to its original position. The package 1 is opened and closed by the opening/closing means 34 after returning and stopping the operation of the suction device 90.
It is also possible to configure the system to automatically perform the 0 blockage.

Further, by providing a limit switch that detects the end of rotation of the opening/closing means 34 in the direction of arrow H, and configuring the discharge member drive device to be linked to this limit switch, the package 10 can be automatically discharged. I can do it.

That is, as described above, the package 10 is removed from the opening 38.
It is possible to configure the system so that all the operations following the insertion operation are automatically and continuously executed. In this case, the operator can simply peel off the adhesive tape stuck to the front A side of the package 10. The loading of the film is completed by simply inserting the package 10 into the package receiving mechanism 26 through the opening 38.

Note that even if the film in the package 10 is not completely finished and you want to use a film of another size, the film inside is shielded from light by performing the above-mentioned ejecting operation of the package 10. Since it is possible to take out the package 10 from inside the casing 22 while the package 10 is still in use, even if there is any film left inside the package 10, the remaining film can be freely replaced with another type of film midway through without wasting the remaining film. I can do it.

Next, in FIGS. 8 and 9, second and third examples of packaging bodies according to the present invention are shown. In addition, in FIG. 8 and FIG. 9, the same reference numerals as above indicate the same components.

A package 92 shown in FIG. 8 uses light shielding members 94 and 96 having a plurality of side wall portions forming layers in the horizontal direction. In this case, as shown in the figure, the light shielding member 94
．． Since the plurality of side wall portions 96 are alternately and loosely fitted to form a so-called labyrinth structure, the intrusion of light and moisture is preferably prevented, and a more complete light-shielding and moisture-proofing effect can be obtained.

A packaging body 98 shown in FIG.
00 is adopted, and the part on the back B side of the box 100 is fixed to the lower box 14. In this case, since the portion of the upper box 100 that is displaced when the package 98 is opened is relatively small, the opening/closing plate 8 constituting the opening/closing means 34 correspondingly becomes relatively small.
0 and 82 are shorter, and because less space is required to open the package 98, the package receiving mechanism 26 can be made smaller.

According to the present invention, as described above, it is possible to use low-cost members as materials for the packaging body that houses the film,
For this reason, the packaging itself is inexpensive, and since the packaging provides suitable light-shielding and moisture-proof conditions, it is also suitable for storing films.Furthermore, the packaging is box-shaped and can be opened and closed, allowing it to function as a magazine. This makes it easy to take out the film inside the package inside the light-shielded casing, which eliminates the problems of conventional methods such as light intrusion and the complexity of the mechanism when using a light-shielding bag and a special magazine. In addition, the film loading operation can be easily automated, and as a result, the film loading operation can be simplified.

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.
