Description

  The present invention relates to a protective cover for a photoconductor for X-ray imaging used for intraoral X-ray imaging.

  As a measure for diagnosing caries, periodontal disease, etc., X-ray photography of the mouth is widely performed. One of the methods for X-ray imaging of the mouth is the mouth method. The intraoral method is a general term for measures for putting a photosensitive film in the mouth and exposing the photosensitive film by irradiating X-rays from the outside. The photosensitive film inserted into the mouth is packaged with a light-shielding film that transmits only X-rays and blocks sunlight or the like, and is mounted in the mouth. Then, after photographing, the packaging is removed in a dark room or the like, and the photosensitive film is taken out and developed.

  By the way, in recent years, an opportunity to use an imaging plate for X-ray photography instead of a photosensitive film has increased. The imaging plate is a photoconductor that can record an X-rayed image in a digital manner, and can be reused unlike an X-ray film.

  The imaging plate 100 used for the intraoral method has an external shape as shown in FIG. That is, the imaging plate 100 is a thin plate member with rounded four corners of a rectangle. The imaging plate 100 has a photosensitive surface 100a that is sensitive to X-rays. That is, the image data is recorded in digital format on the photosensitive surface 100a.

  For example, the imaging plate 100 is accommodated in a package 101 as shown in FIG. The packaging body 101 is a bag-like member having an internal space 102 for housing the imaging plate 100 and an opening 103 and having a function of shielding sunlight and the like. An adhesive tape 105 is provided in the opening 103. The package 101 accommodates the imaging plate 100 in the internal space 102 through the opening 103 (FIG. 10B). Then, as illustrated in FIG. 10C, the opening 103 is closed by the adhesive tape 105.

  Moreover, the package 110 as shown to Fig.11 (a) is also used conventionally. The package 110 includes a front side sheet 111 and a back side sheet 112. The front side sheet 111 and the back side sheet 112 are closed on three sides to form an accommodation space inside, and the remaining one side is opened to form an opening 113. The front sheet 111 is shorter than the back sheet 112. The imaging plate 100 is accommodated inside the package 110 (FIG. 11B), and the opening 113 is closed by bending the back sheet 112 along the opening 113 of the front sheet 111 or the imaging plate 100 (FIG. 11C). )). When the opening 113 is closed, corners 117 are formed in the package 110 as shown in FIG.

  Furthermore, as shown in FIG. 12A, a package 106 different from the packages 101 and 110, which is sufficiently longer than the length of the imaging plate 100, has been conventionally used. The package 106 has an opening 109 and an internal space similar to that of the package 101 of FIG. However, the opening 109 is not provided with an adhesive tape. As shown in FIG. 12 (b), after the packaging body 106 houses the imaging plate 100 in the internal space, the end on the opening 109 side is formed as shown in FIGS. The bent portion 106a is formed by bending in three stages, and the opening 109 is closed. Further, as shown in FIG. 12 (f), the cover 106 is fixed so that the bent portion 106a is not opened. The lid member 108 has a storage space in which a part of the package 106 can be stored, and an opening 108a that is an entrance of the storage space. That is, the bent portion 106 a of the package 106 is accommodated in the accommodating space from the opening 108 a of the lid member 108.

  The packaging bodies 101, 106, and 110 that contain the imaging plate 100 are held by a holder 104 shown in FIG. In FIG. 13, the case where the package 110 (FIG. 11) is held by the holder 104 among the packages 101, 106, 110 is depicted.

  The holder 104 has a holding part 114 and a fixing part 115. The holding unit 114 holds the package 110 in which the imaging plate 100 is stored from the left and right. The fixing unit 115 is a block-shaped part extending in a direction orthogonal to the imaging plate 100 held by the holding unit 114. When the fixing unit 115 is bitten by the upper and lower teeth of the patient, the holding unit 114 (imaging plate 100) is disposed at a predetermined position in the patient's mouth. When the package 110 containing the imaging plate 100 is placed in the mouth of a patient, X-rays are irradiated by an X-ray irradiation device (not shown) and X-ray imaging is performed.

When the X-ray imaging is completed, the package 110 containing the imaging plate 100 is taken out from the mouth of the patient, the package 110 is removed from the holder 104, and the imaging plate 100 is taken out from the package 110.
Since the package 110 has been placed in the mouth of the patient, saliva is attached. For hygiene purposes, the photographer holds the package 110 in a gloved state and takes out the imaging plate 100 inside.

  Then, the imaging plate 100 is loaded into an image processing apparatus (not shown), and image data recorded on the imaging plate 100 is copied to the image processing apparatus. Then, the dentist displays an X-ray image of the tooth on a display or prints it with a printer to diagnose the patient's teeth.

JP-A-6-289543 Japanese Patent No. 2888451

  Incidentally, there is room for improvement in the packaging bodies 101, 106, and 110 that accommodate the above-described imaging plate 100 as described below.

  Patients undergoing X-ray imaging by the intraoral method often have abnormalities in their teeth and periodontal, and are often accompanied by pain and swelling. When the packaging bodies 101, 106, and 110, which are foreign objects, are accommodated in such a patient's mouth, the packaging bodies 101, 106, and 110 touch the affected area, and the patient feels pain.

  For example, when the package 110 shown in FIG. 11 (c) is held by the holder 104 (FIG. 13) and placed in the patient's mouth, the package 110 is formed with a corner 117. When the patient touches the patient's mouth (especially the affected area), the patient feels pain.

  Further, in order to hold the package 101 shown in FIG. 10C with the holder 104 (FIG. 13), the package 101 must be bent. A corner portion 107 (FIG. 10D) is formed on the folded package 101. When the corner 107 touches the patient's mouth, the patient still feels pain.

  Furthermore, in the package 106 shown in FIG. 12 (f), the corner portion 116 is formed by the bent portion 106a, but the corner portion 116 is not exposed by covering the bent portion 106a with the lid member 108 having the opening 108a. The lid member 108 contacts the patient's mouth instead of the bent portion 106a (corner portion 116). Since the corner portion of the lid member 108 is rounded, pain caused by touching the mouth is reduced. However, after taking an image, when the imaging plate 100 is taken out from the package 106, the lid member 108 must first be removed from the package 106, and then the bent portion 106a must be opened. Since the folded portion 106a has a folded fold, the opening 109 of the package 106 is difficult to open. Therefore, the photographer cannot easily take out the imaging plate 100 in the package 106 to the outside.

  Therefore, the present invention protects a photoconductor during X-ray imaging, and protects a photoconductor for intraoral X-ray imaging that can be easily taken out without adhering saliva to the photoconductor after X-ray imaging. It is an object to provide a cover.

  The invention according to claim 1 for solving the above-mentioned problems is a protective cover for a photoconductor for X-ray imaging which is disposed in the mouth and used for X-ray imaging of the teeth of the upper and lower jaws. The protective cover includes an interior member provided with a photoreceptor accommodating portion that accommodates part or all of the photoreceptor, and an exterior member provided with an interior member accommodating portion that accommodates part or all of the interior member. The interior member has an interior side opening through which a photoreceptor can be taken in and out, and the interior member housing part of the exterior member has an exterior side opening through which the interior member can be taken in and out. The interior member can be accommodated in the interior member accommodating portion of the exterior member in a state where the photoreceptor is accommodated in the photoreceptor accommodating portion of the interior member, and the interior member in which the photoreceptor is accommodated in the photoreceptor accommodating portion is provided. The interior member is accommodated in the interior member accommodating portion of the exterior member. It is possible to extract from the exterior side opening of the packaging member accommodating portion, and at this time, the photoreceptor is extracted from the interior side opening of the photoreceptor accommodating portion of the interior member, and the photoreceptor is left in the interior member accommodating portion of the exterior member. This is a protective cover for a photoconductor for intraoral X-ray photography.

According to the first aspect of the present invention, the photoreceptor is accommodated in the photoreceptor accommodating portion of the interior member, and further, the interior member is accommodated in the interior member accommodating portion of the exterior member. Double protection is provided by the exterior member. For this reason, when the photoreceptor is placed in the patient's mouth, saliva is less likely to adhere to the photoreceptor.
The interior member can be extracted from the exterior side opening of the interior member accommodating portion in a state where the interior member accommodating the photoreceptor in the photoreceptor accommodating portion is accommodated in the interior member accommodating portion of the exterior member. Then, the photoreceptor remains in the interior member housing portion of the exterior member.
Since the interior member accommodating portion can accommodate the interior member, a clearance is generated between the interior member accommodating portion and the photosensitive member. Therefore, the photoconductor can be easily moved in the interior member housing portion. That is, when the exterior side opening is faced downward, the photoreceptor is dropped, and the photoreceptor can be taken out from the exterior member without touching the photoreceptor.
Therefore, the photoconductor can be taken out from the protective cover to which the patient's saliva is adhered without touching the photoconductor. Further, the photoconductor can be taken out from the protective cover without adhering saliva to the photoconductor.

  According to the second aspect of the present invention, when a part of the photoconductor is exposed from the photoconductor housing portion of the interior member and the photoconductor is extracted from the interior opening of the photoconductor housing portion, an external force is applied from the outside of the exterior member. 2. The protective cover for a photoconductor for intraoral X-ray photography according to claim 1, wherein the exposed portion of the photoconductor can be held by hanging.

  According to the second aspect of the present invention, since a part of the photoreceptor is exposed from the photoreceptor housing portion of the interior member, when the interior member is housed in the interior member housing portion of the exterior member, a part of the photoreceptor is interior. It is exposed in the member accommodating portion. For this reason, since it is possible to apply an external force directly to the exposed portion of the photoreceptor through the exterior member and hold it, the photoreceptor can be fixed to the exterior member. Since the interior member is not fixed to the exterior member, only the interior member can be pulled out with the photosensitive member remaining in the interior member housing portion.

  The invention according to claim 3 is characterized in that a notch or a recess is provided in the interior side opening of the photoreceptor housing portion, and a part of the photoreceptor is exposed through the notch or the recess. A protective cover for a photoconductor for intraoral X-ray photography according to claim 1 or 2.

  According to the third aspect of the present invention, the interior side opening of the photoreceptor housing portion is provided with a notch or a recess, and a part of the photoreceptor is exposed through the notch or the recess. The exterior member and the photoreceptor can be gripped from the outside of the member, and only the exterior member and the photoreceptor can be fixed.

  In the invention according to claim 4, the interior member and the exterior member are each a bag-shaped member having four sides, and at least a vertex portion of each of the interior member and the exterior member intersecting each side of the exterior member is a circle. 4. The protective cover for a photoconductor for intraoral X-ray imaging according to claim 1, wherein the protective cover is formed in an arc shape.

  In the invention according to claim 4, at least one of the interior member and the exterior member at which the sides of the exterior member intersect each other is formed in an arc shape, so that no corner is formed on the protective cover. For this reason, when the protective cover is placed in the patient's mouth, it is difficult to press the mouth. In addition to being sensitive in the mouth, in the case of X-ray photography, the mouth is often inflamed or damaged. It is painful for the patient to place the photoreceptor, which is a foreign substance, in such a mouth while being accommodated in the protective cover. However, the protective cover according to the present invention can reduce pressure on the mouth and relieve the patient's pain.

  The interior member and the exterior member are each composed of a front side sheet and a back side sheet having four sides, the three sides of the front side sheet and the three sides of the back side sheet are in close contact, and three sides are closed, A photosensitive member accommodating portion and an interior member accommodating portion of an exterior member are formed, and at least one of the back side sheets has a light shielding property and extends to the opening side from the front side sheet, A notch or a recess is formed in the interior side opening side of the back sheet of the member, and when the photoreceptor is accommodated in the photoreceptor accommodating portion of the interior member, an intraoral method is formed so that exposed portions are formed on both sides of the photoreceptor. A protective cover for a photoconductor for X-ray photography can also be configured.

  The protective cover of the present invention does not require saliva to adhere to the photoconductor when it is placed in the patient's mouth. In addition, after X-ray photography, the photoconductor is removed from the protective cover without touching the photoconductor. It can be taken out. Therefore, it is hygienic, it is not necessary to clean the photoconductor, and the work efficiency is good.

Hereinafter, the protective cover of the embodiment of the present invention will be described.
First, the imaging plate 4 (photosensitive member) will be described with reference to FIG. The imaging plate 4 is a member configured by applying a material that emits fluorescence when irradiated with a laser beam after receiving X-rays to a plastic substrate (organic film). That is, the imaging plate 4 has a photosensitive surface 5. The outer shape of the imaging plate 4 has a substantially rectangular thin plate shape. The four corners of the imaging plate 4 are processed into an arc shape (R processing).

  The imaging plate 4 that has been exposed to X-rays by an X-ray irradiation device (not shown) is loaded into a processing device (not shown), and a photographed X-ray image is copied (extracted) to the processing device side. After copying, the image data recorded on the imaging plate 4 is erased by the processing device. The imaging plate 4 from which the image data has been erased is reused.

  Next, the protective cover 1 will be described.

  As shown in FIG. 1B, the protective cover 1 has an interior member 2 and an exterior member 3.

  The interior member 2 includes a front side sheet 6 made of, for example, polyethylene or polyolefin, and a back side sheet 7. The front side sheet 6 transmits light and can visually recognize the inside of the accommodating portion 11 described later. The back sheet 7 has a light shielding function (light shielding part). The front sheet 6 and the back sheet 7 are thin, substantially rectangular sheet members that are easily deformed when pressed. The length of the front sheet 6 is shorter than the length of the back sheet 7. Further, the three sides of the front sheet 6 are welded to the three sides of the back sheet 7, and the opening 10 is formed on the other one side. That is, an exposed portion 7 a exposed from the front sheet 6 is formed on the front side of the back sheet 7. A cutout portion 13 is provided on the end side 12 of the exposed portion 7a. The notch 13 is a recess having a shape in which the end side 12 (edge) is recessed.

  Further, as shown in FIG. 1B, a bottom portion 9 is formed on the side opposite to the end side 12 in the interior member 2. The bottom portion 9 is a portion where the front side sheet 6 and the back side sheet 7 are welded. The bottom portion 9 is formed with a protruding portion 14 that protrudes outward in the same plane as the interior member 2. The four corners of the interior member 2 and the exterior member 3 are preferably rounded in an arc shape in accordance with the shape of the imaging plate 4.

  A storage portion 11 (storage space) is formed between the front sheet 6 and the back sheet 7. The accommodating portion 11 is a space that is closed on three sides by a bottom portion 9 and side portions 8 a and 8 b that are continuous with the bottom portion 9. The accommodating portion 11 communicates with the outside via the opening 10. The distance between the side portions 8a and 8b in the accommodating portion 11 is set to a distance that can just accommodate the imaging plate 4. Further, the length of the back sheet 7 is substantially the same as the length of the imaging plate 4. That is, the length of the front sheet 6 is shorter than the length of the imaging plate 4.

  The exterior member 3 includes a front side sheet 16 and a back side sheet 17 made of the same material as the interior member 2. The front sheet 16 and the back sheet 17 are substantially rectangular sheet members. The length of the front sheet 16 is shorter than the length of the back sheet 17. Further, the three sides of the front sheet 16 are welded to the three sides of the back sheet 17, and an opening 20 is formed on the other side. That is, an exposed portion 17 a exposed from the front sheet 16 is formed on the front side of the back sheet 17.

  As shown in FIG. 1B, a bottom 19 is formed on the side of the exterior member 3 opposite to the end side 22. The bottom portion 19 is a portion where the front side sheet 16 and the back side sheet 17 are welded. A projecting portion 24 that projects outward in the same plane as the exterior member 3 is formed on the bottom portion 19.

  A storage portion 21 (storage space) is formed between the front sheet 16 and the back sheet 17. The accommodating portion 21 is a space closed on three sides by the bottom portion 19 and the side portions 18 a and 18 b continuous with the bottom portion 19. The accommodating portion 21 communicates with the outside via the opening 20. The distance between the side portions 18 a and 18 b in the housing portion 21 is set to a distance that can just accommodate the interior member 2. Further, the length of the back sheet 17 is substantially the same as the length of the interior member 2.

Next, a procedure for housing the imaging plate 4 in the protective cover 1 will be described.
As shown in FIG. 2, the imaging plate 4 is first accommodated in the accommodating portion 11 of the interior member 2. That is, the imaging plate 4 is inserted into the housing portion 11 from the opening 10 of the interior member 2 so that the photosensitive surface 5 faces the back sheet 7 (light shielding side). The imaging plate 4 comes into contact with the bottom 9 in the housing 11 and stops. At this time, the end side 12 of the back sheet 7 and the end side of the imaging plate 4 substantially coincide. Further, the distance between the side portions 8a and 8b in the accommodating portion 11 is a length that can accommodate the imaging plate 4 just. Therefore, a slight resistance is generated when the imaging plate 4 is put in and out of the interior member 2.

  Further, as shown in FIG. 2B, a part of the back side of the imaging plate 4 is exposed from the notch 13 of the back side sheet 7. Further, a part (exposed portion 15) on the surface side of the imaging plate 4 is exposed from the front sheet 6 as shown in FIG. The front side sheet 6 is transparent, and the imaging plate 4 in the accommodating part 11 can be visually recognized.

  As shown in FIG. 3, the interior member 2 that accommodates the imaging plate 4 is accommodated in the exterior member 3. As shown in FIG. 4A, the interior member 2 is accommodated from the opening 20 of the exterior member 3 into the accommodation portion 21 as shown in FIG. At this time, as shown in FIG. 3B, the protruding portion 14 of the interior member 2 projects from the end side 22 of the exterior member 3. The exposed portion 15 of the imaging plate 4 is blocked from the outside by the exterior member 3. As shown in FIG. 3B, the notch 13 (FIG. 2B) of the interior member 2 is close to the protrusion 24 of the exterior member 3.

  The distance between the side portions 18a and 18b in the accommodating portion 21 is a length that can just accommodate the imaging plate 4. Therefore, a slight resistance occurs when the interior member 2 is taken in and out of the exterior member 3. The photosensitive surface 5 of the imaging plate 4 is shielded from sunlight and the like by the back side sheet 7 of the interior member 2 and the back side sheet 17 of the exterior member 3. Furthermore, the photographer can visually recognize the imaging plate 4 through the transparent front side sheet 6 of the interior member 2 and the transparent front side sheet 16 of the exterior member 3.

  The imaging plate 4 (FIGS. 3A and 3B) accommodated in the protective cover 1 is held by the holder 30 or the holder 40 shown in FIG. 7A or FIG. X-ray imaging is performed in the mouth. The holder 30 is used when holding the imaging plate 4 in a vertical posture. The holder 40 is used when holding the imaging plate 4 in a horizontal posture. The holder 30 (or 40) supports three sides (three sides) of the four sides (four sides) of the protective cover 1 in which the imaging plate 4 is accommodated. The protective cover 1 is held by the holder 30 (or 40) and is placed in the patient's mouth. The four corners of the interior member 2 and the exterior member 3 are rounded in an arc shape. Therefore, even if the protective cover 1 (the interior member 2 and the exterior member 3) hits the patient's mouth, the patient hardly suffers pain.

  Moreover, since the imaging plate 4 is doubly protected by the interior member 2 and the exterior member 3, it is difficult to form a tooth profile when the patient accidentally bites. Therefore, the protective cover 1 can improve the durability of the imaging plate 4. After X-ray imaging, the holder 30 (40) is taken out from the patient's mouth, and the imaging plate 4 protected by the protective cover 1 is removed from the holder 30 (or 40).

  The photographer (or dentist) holds the protective cover 1 with his gloved hand and takes out the imaging plate 4. Specifically, as shown in FIG. 5A, the photographer grasps the vicinity of the protruding portion 24 of the exterior member 3 and grasps the imaging plate 4 through the exterior member 3. That is, in the vicinity of the protruding portion 24, there is a cutout portion 13 of the interior member 2, and the backside of the imaging plate 4 is exposed in the housing portion 21 of the exterior member 3 by the cutout portion 13. The protrusion 24 has both a function as an index indicating the position of the notch 13 of the interior member 2 and a function of making it easier to hold the exterior member 3 when the photographer pulls out the interior member 2 from the exterior member 3.

  Further, since the front side sheet 6 of the interior member 2 is shorter than the back side sheet 7, the surface side of the imaging plate 4 is also exposed in the accommodating portion 21 of the exterior member 3. Therefore, since the front and back of the imaging plate 4 are exposed in the housing portion 21 of the exterior member 3, the photographer can grasp the exposed portion through the exterior member 3. The photographer grips the protruding portion 14 of the interior member 2. Here, the protruding portion 14 protrudes outward from the bottom portion 9 of the interior member 2. Therefore, the protrusion 14 and the imaging plate 4 do not overlap. Then, as shown in FIGS. 5B and 5C, the photographer pulls out the interior member 2 from the exterior member 3.

  As a result, the imaging plate 4 remains in the housing portion 21 of the exterior member 3, and the imaging plate 4 is directly housed in the housing portion 21. The interval between the side portions 18 a and 18 b in the accommodating portion 21 is larger than that of the imaging plate 4, and a clearance 25 is generated between the side portion 18 a (side portion 18 b) and the imaging plate 4.

  Therefore, the imaging plate 4 can slide with little resistance relative to the exterior member 3. As shown in FIG. 6A, when the opening 20 of the exterior member 3 is directed downward, the imaging plate 4 in the housing portion 21 slides smoothly with respect to the exterior member 3 by the action of gravity. (FIG. 6B). The imaging plate 4 falls from the exterior member 3 onto a floor surface (not shown).

  Here, in the state shown in FIG. 5A, the photographer is wearing gloves, and the patient's saliva is attached to the protective cover 1. However, by first extracting only the interior member 2 from the protective cover 1 and dropping the imaging plate 4 from the exterior member 3, the imaging plate 4 can be recovered without adhering saliva to the imaging plate 4. The photographer drops the imaging plate 4 onto a clean floor or desk, and picks up the imaging plate 4 with a clean hand from which the glove with saliva attached is removed. That is, the photographer can easily take out the imaging plate 4 in a clean state. Therefore, it is not necessary to wash the imaging plate 4.

  In the embodiment described above, an example in which only the back sheet 7 of the interior member 2 and the back sheet 17 of the exterior member 3 have light shielding properties is shown. Either one may be sufficient. The front side sheet 6 of the interior member 2 and the front side sheet 16 of the exterior member may have a light shielding function. The photosensitive surface 5 of the imaging plate 4 is opposed to the surface having the light shielding function of the interior member 2 and / or the exterior member 3.

  Moreover, although the length of the front side sheet | seat 6 of the interior member 2 showed the example shorter than the back side sheet | seat 7, it does not interfere even if the length of both sheets corresponds. That is, in that case, the front sheet 6 is provided with a notch similar to the notch 13 of the back sheet 7 so as to overlap the notch 13 so that the imaging plate 4 can be grasped through the exterior member 3. Alternatively, the length of the interior member 2 (the depth dimension of the accommodating portion 11) is shorter than the length of the imaging plate 4 so that a part of the imaging plate 4 accommodated in the accommodating portion 11 protrudes from the interior member 2. May be. In this way, a part of the imaging plate 4 protrudes from the housing part 11 of the interior member 2 and is exposed in the housing part 21 of the exterior member 3. Therefore, the imaging plate 4 can be gripped through the exterior member 3.

  The cutout portion 13 provided on the end side 12 of the back sheet 7 can be a recess that is recessed toward the bottom portion 9. The notch 13 (recess) is preferably in the center of the end 12, but may be off the center. A plurality of notches 13 (concave portions) may be provided on the end side 12.

  Further, the length of the interior member 2 (the depth of the accommodating portion 11) may be shorter than the length of the imaging plate 4. If it does in this way, a part of both surfaces of the imaging plate 4 will be exposed in the accommodating part 21 of the exterior member 3. FIG. Therefore, in this case, the cutout portion 13 (concave portion) is not necessary on the end side 12 of the back sheet 7.

  Furthermore, in above-mentioned embodiment, although the side parts 8a and 8b which partition the accommodating part 11 of the interior member 2 were closed over the full length of the front side sheet | seat 6 (shorter sheet | seat), in the side parts 8a and 8b You may make it close from the site | part on the way to the bottom part 9, without closing the opening 10 vicinity. That is, the back sheet 7 and the front sheet 6 need to be closed in the vicinity of the bottom 9 in the side portions 8a and 8b, but may be close to each other on the opening 10 side.

  In the protective cover 1 of the present embodiment, neither the interior member 2 nor the exterior member 3 needs to be bent as in the packaging bodies 106 and 110 in FIGS. 11 and 12, so that corners are not formed. Therefore, it is difficult to press the patient's mouth and to hurt.

  Further, in the example shown in FIG. 1, the imaging plate 4 can be moved in the longitudinal direction of the interior member 2 (left and right as viewed in FIG. 1) so that it can be accommodated in and removed from the accommodating portion 11. However, the opening 10 may be closed, and the side 8a or 8b may be opened instead. And you may make it make it enter / exit into the accommodating part 11 through the side part 8a or 8b which opened the imaging plate 4. FIG. Similarly, the opening 20 of the exterior member 3 may be closed, the side portion 18a or 18b may be opened, and the interior portion 2 may be opened or removed through the side portion 18a or 18b.

  When only the side portion 8a (or side portion 8b) of the interior member 2 is opened, the interior member 2 may be taken in and out through the opening 20 of the exterior member 3 shown in FIG. Only the side portion 18a (or side portion 18b) of the third side may be opened, and the interior member 2 may be taken in and out from the opened side portion 18a (or side portion 18b) portion.

  That is, the interior member 2 may open the short side (opening 10) of the imaging plate 4, and the exterior member 3 may open the long side (side portions 18a and 18b) of the imaging plate 4. Similarly, the interior member 2 may open the long side (side portions 8a and 8b) of the imaging plate 4, and the exterior member 3 may open the short side (opening 20) of the imaging plate 4. Furthermore, the interior member 2 may open the long side (side portions 8a and 8b) of the imaging plate 4, and the exterior member 3 may also open the long side (side portions 18a and 18b) of the imaging plate 4. .

  In order to open only the side part 8a (or side part 8b) of the interior member 2, the side part 8a (or side part 8b) side of the front side sheet 6 is made shorter than the back side sheet 7, and further to the back side sheet 7 A notch such as the notch 13 is provided. Or the accommodation depth of the accommodating part 11 is set so that a part of imaging plate 4 may protrude from the side part 8a (or side part 8b). And the protrusion part like the protrusion part 14 is provided in the closed side part 8b (or side part 8a) of the interior member 2.

  Next, a protective cover according to another embodiment will be described with reference to FIG.

  Fig.8 (a) shows the protective cover 31 of embodiment different from FIGS. As shown in FIG. 8A, the protective cover 31 has an interior member 32 and an exterior member 33. The interior member 2 and the exterior member 3 shown in FIG. 1 are provided with openings 10 and 20 on the short side of a rectangle and the other three sides are closed, but in the protective cover 31 shown in FIG. Openings 34 and 35 are provided on the long side (lower side) of the interior member 32 and the long side (upper side) of the exterior member 33, and the other three sides of the interior member 32 and the exterior member 33 are closed. It is different.

  The interior member 32 and the exterior member 33 have a front side sheet and a back side sheet similar to the interior member 2 and the exterior member 3 shown in FIG. 1, and accommodating portions 42 and 43 are formed between the two sheets, respectively.

  The accommodating portion 42 of the interior member 32 communicates with the opening 34, and the imaging plate 4 can be accommodated in the accommodating portion 42 via the opening 34. A notch 38 is provided in the opening 34 (the front sheet and the back sheet), and when the imaging plate 4 is accommodated in the accommodating part 42, a part of the imaging plate 4 is exposed from the notch 38.

  The accommodating portion 43 of the exterior member 33 communicates with the opening 35, and the interior member 32 can be accommodated in the accommodating portion 43 through the opening 35. When the interior member 32 is accommodated in the accommodation portion 43, the protruding portion 37 of the interior member 32 protrudes from the opening 35, and the state shown in FIG.

  After X-ray imaging, the protrusion 37 of the interior member 32 of the protective cover 31 shown in FIG. 8B is held with one hand, and the vicinity of the protrusion 41 of the exterior member 33 is held with another hand. A cutout portion 38 of the interior member 32 is disposed in the vicinity of the protruding portion 41, and the imaging plate 4 is exposed in the housing portion 43 from the cutout portion 38. Therefore, when the vicinity of the protrusion 41 is provided, the exterior member 33 and the imaging plate 4 can be grasped simultaneously. Therefore, the interior member 32 can move with respect to the exterior member 33 and the imaging plate 4, and the interior member 32 can be pulled out from the protective cover 31. When the interior member 32 is pulled out, the imaging plate 4 comes out of the accommodating portion 42 of the interior member 32 and is disposed in the accommodating portion 43 of the exterior member 33. A clearance (not shown) is generated between the housing portion 43 of the exterior member 33 and the imaging plate 4. The clearance (not shown) is the same as the clearance 25 shown in FIG. 5C and FIG. For this reason, when the opening 35 is directed downward, the imaging plate 4 falls out of the housing portion 43 of the exterior member 33 through the opening 35 and falls.

FIG. 9A and FIG. 9B show still another embodiment.
As shown in FIG. 9A, the protective cover 51 has an interior member 52 and an exterior member 53.

  The interior member 52 has a front side sheet 48 and a back side sheet 49, and an accommodating portion 47 is formed between both sheets. The interior member 52 is different from the interior member 2 in FIG. 1 and the interior member 32 in FIG. 8 in that two adjacent sides (long side and short side) of the four sides are open. That is, the interior member 52 is provided with open sides 56 and 57 and closed sides 58 and 59. A protruding portion 54 is provided on the closed side 58 (long side) of the interior member 52. A cutout 55 is formed in the opening side 57 (long side) of the interior member 52.

  Similarly to the interior member 52, the exterior member 53 has a front side sheet 61 and a back side sheet 62. A storage portion 65 is formed between the sheets 61 and 62. Two adjacent sides (long side and short side) of the four sides of the exterior member 53 are open. That is, the exterior member 53 is provided with open sides 66 and 67 and closed sides 68 and 69. A protruding portion 64 is provided on the closing side 68 (long side) of the exterior member 53.

The opening sides 56 and 57 of the interior member 52 are closed by the closing sides 69 and 68 of the exterior member 53, and the opening sides 66 and 67 of the exterior member 53 are closed by the closure sides 59 and 58 of the interior member 52. The imaging plate 4 is isolated from the outside.

  When the imaging plate 4 is taken out from the protective cover 51 shown in FIG. 9B, first, the outer member 53 and the imaging plate 4 are gripped at the same time by holding the vicinity of the protruding portion 64 of the outer member 53. Since the notch 55 of the interior member 52 is disposed in the vicinity of the projecting portion 64, the exterior member 53 and the imaging plate 4 can be gripped simultaneously if the projecting portion 64 is present. And it has the protrusion part 54 of the interior member 52, and the interior member 52 is pulled out.

  As a result, the imaging plate 4 is disposed directly in the housing portion 65 of the exterior member 53. A clearance is generated between the housing portion 65 and the imaging plate 4, and the imaging plate 4 can move within the housing portion 65 with little resistance. Therefore, when the opening side 66 or 67 is directed downward, the imaging plate 4 falls from the exterior member 53.

  In the above-described embodiment, the imaging plate is employed as the photosensitive member, but a photosensitive member (X-ray film) other than the imaging plate can be similarly protected by the protective cover 1. That is, the X-ray film covered with the light shielding cover is accommodated in the protective cover 1 (the interior member 2 and the exterior member 3), and after the X-ray photography, the photographed X-ray film covered with the light shielding cover is packaged. Drop from the member 3 and take it out. Saliva is not attached to the light shielding cover of the X-ray film in this state, and it is hygienic. Therefore, no cleaning is required and development can be performed immediately in a dark room.

  In addition, there are two types of imaging plates 4 for children and adults, and the imaging plate 4 for children is slightly smaller than the imaging plate 4 for adults. Therefore, the sizes of the protective cover 1 (interior member 6, exterior member 7), protective cover 31 (interior member 32, exterior member 33), and protective cover 51 (interior member 52, exterior member 53) of each embodiment described above. Is arbitrarily set according to the size of each imaging plate 4 for children and adults.
