Description of the Invention: [Technical Field] The present invention relates to an intraoral photographic aid capable of displaying an image obtained by photography. [Prior Art] Patent Document 1 proposes a dental X-ray imaging apparatus and is used for performing dental imaging using an X-ray apparatus. The dental X-ray apparatus includes a flat substrate, a light-receiving portion to which an X-ray film is attached, and a ring portion for determining an X-ray irradiation direction. When photographing the teeth, the examinee bites the holding substrate with the teeth, thereby fixing the position of the X-ray film relative to the teeth of the photographic subject. The photographer irradiates the subject's teeth with X-rays. Then, the photographer refers to the X-ray film which has been subjected to development. When an X-ray imaging element is mounted on the X-ray receiver, the display of the personal computer provided outside the dental X-ray apparatus displays the image output by the X-ray imaging element. [Problem to be Solved by the Invention] However, a person who cannot be well engaged, such as a child, cannot reliably hold a dental X-ray apparatus. Therefore, the dental X-ray apparatus relatively moves the teeth of the subject, and there is a possibility that the teeth of the subject cannot be reliably photographed. r 099117736 3 The present invention is directed to the photographic material of the photographic material. The purpose of the invention is to obtain an intraoral photographic aid that can be used as a means of solving the problem. The intraoral view of the present invention, the wrist, has a pluggable to %"", which is characterized in that it has an insertion portion that supports the extension to the outside of the mouth, and an extension from the insertion portion and a protruding connection. The end portion, like the receiving portion, is attached to the insertion portion and is not extended. The wrist does not have the interference with the teeth of the photographic subject. This kind of temperament/shadow aid is used. The person who keeps the support of the wrist to fix the oral cavity can also be easily and surely the child can not be well engaged. X-ray photography. =: It is possible to keep the image receiving unit and to rotate freely. The photographic aid device further has an image receiving surface of the body image; the above-mentioned mouth singer further has an indication portion which is extended from the direction of the right angle of the receiving surface of the image, +, ^ _ _ _ _ _ Extending from the image receiving portion so that; = degree refers to the path of the subject image; and the position indicating wrist is from the corner sound; = the end connected to the image receiving portion is said to be the best:: =: wrist precursor _ The specific position of the mm on the image receiving surface when the receiving surface is projected at a right angle. Since the image receiving body is located in the subject (4) during light photography, it is difficult for the photographer to know the position of the image receiving body mounting portion 20. However, according to the present embodiment, the photographer can grasp the position of the image receiving body mounting portion 20 via the viewing instructing portion 61. The angle indicating one part of the wrist and the position indicating wrist are preferably protruding out of the mouth. Further, a display unit for displaying an image output from the image receiving unit may be further provided, and the display portion may be attached to the support wrist. In this way, the photographer can view the image displayed on the display unit 40 to confirm the photographing result. In the case where an image is displayed on the display of a personal computer, in order to view the image, the direction in which the photographer observes must be changed from the teeth of the examinee to the display. In general, the occlusion position of the substrate 10 or the position of the X-ray device 50 is adjusted by the occlusion of the teeth, and the photographing is performed plural times. Therefore, it is very troublesome for the photographer to frequently change the viewing direction. According to this embodiment, the photographer does not need to change the viewing direction, but can simultaneously view a certain area of the examinee's teeth and an area where the image is displayed, so that the photographing result can be quickly confirmed. Preferably, the display unit is provided with a display surface for displaying an image, and is mounted so as to be rotatable relative to the support wrist so that the display surface faces the direction of the radiation source or the direction of the image receiving portion. By rotating the display surface of the display unit, the display surface can be directed toward the X-ray device side where the photographer is located, or toward the subject side, so that the photographer or the examinee can easily observe the image. When the examinee performs several times of photographing in a state in which the substrate is held by the occlusion, the face cannot be largely moved. However, according to the present invention, the examinee can see the image of the photographic result without largely moving the face. . ^ 099117736 5 201103488 Intraoral photography aids can also be constructed to have more: 1st slow line, set inside the wrist and support wrist, and connected to the image receiving part; and 2nd line 'set in the plug The inside of the wrist and the wrist are connected to the display; the image of the image received by the image receiving unit is output via the i-th line, and the part is processed in the σ cavity. The image processing unit is processed by the image processing unit. Since the communication is performed via the first and second line members provided inside the holding substrate, it is possible to prevent the cable from coming into contact with the inside of the mouth of the subject. It is better to have a grip for the women's extension at the extension. The photographer can securely fix the lion's cavity photography lion by holding the grip.

The video signal is transmitted from the first cable 11 to the display unit 40 of the display unit 40, and the support surface is a display surface 41 from the support wrist 1 〇 0991 Π 736: a rectangular flat plate. In addition, the ax rotation of the vertical axis of the wrist 10 is slightly extended. It is installed in the second system of the wrist 1G. 201103488 12 ’ is used to connect the image processing unit and the display unit of the personal computer. The personal computer transmits power and video signals to the display unit via the second browsing line 12, and displays the image based on the video signal on the display surface 41. Next, the connecting means of the image receiving body mounting portion 20 and the short arm portion 10b will be described with reference to Fig. 2 . The image receptor mounting portion 20 and the short arm portion 10b are connected by a universal joint (free joint) 13 so as to be freely rotatable. The universal joint 13 is composed of a ball portion 14 and a receiving portion 21. The ball portion 14 is spherical and is attached to the front end of the rod extending from the short wrist portion 1b. The receiving portion 21 is provided on the back surface of the surface on which the X-ray image receiving body 25 is mounted in the image receiving body mounting portion 2A. The receiving portion 21 has a spherical recess having a diameter slightly larger than the outer diameter of the ball of the ball portion. The ball portion 14 is housed in the recess of the receiving portion 21, and is frictionally engaged with the inner circumference of the recess. The frictional force generated between the ball portion μ and the receiving portion 21 is such that the size of the image receiving body mounting portion 20 can be moved by the photographer using the finger force, and the image receiving body is mounted even when an external force is slightly applied. The size of the part 2 does not move. In this way, the image receiving body mounting portion supports free rotation of the 1Gb. The photographer can move the sight image receiving body portion 20' to adjust the angle to the short wrist portion 10b. Next, a means for photographing with the i-th intra-oral photographic assisting device T will be described using FIG. u 'The examinee is such that the angle of the examiner's mouth is fixed to the long wrist 10a and the short wrist 099117736 8 201103488 minor angle side when the tooth τ of the photographing object in the joint portion of the 1 (10) is the left deep tooth. Including the first intraoral photography aid 1 . Then, one portion of the support wrist 10 and the image receptor mounting portion 20 are inserted into the oral cavity of the examinee, and the dent of the photographic subject tooth T and the support wrist 10 are perpendicular, and are held by the photographer or the examinee. Part 15. In this manner, the X-ray light-receiving body 25 is placed on the back side of the photographic subject tooth T. At this time, the first intraoral photography assisting device 1 does not have a member that interferes with the imaging subject T. The photographer or the examinee maintains the X-ray apparatus 50 in a manner in which the X-ray irradiation direction, the position of the tooth T, and the positional relationship of the X-ray light-receiving body 25 are suitable for the bisecting method. At this time, the angle of the image receiving body mounting portion 20 to the support wrist 10 can be changed to make it suitable for the angle of the bisecting method. Then, the photographer can irradiate the X-rays to perform photography. The video signal output from the X-ray light receiving unit 25 is transmitted to the personal computer via the first cable 11, and image processing is applied to the image processing unit of the personal computer. The image signal after the image processing is transmitted to the display unit 40 via the second cable 12, and the image based on the image signal is displayed on the display unit 40. The display unit 40 is provided in a portion of the support wrist 10 that is not inserted into the oral cavity of the examinee when the examinee includes the intraoral imaging assisting device 1. At the time of shooting, the display surface 41 of the display unit 40 is disposed to face the X-ray device 50. In this manner, the photographer can view a certain area of the tooth T of the subject of the examinee while observing the image displayed on the display unit 40. On the other hand, the display unit 40 may be arranged to rotate so that the display surface 41 of the display unit 40 [s 099117736 9 201103488 faces the subject. At this time, the examinee can observe the image displayed on the display unit 40. In this way, the photographer can view the image displayed on the display unit 40 and confirm the result of the photographing. In the case where the display of the display on the personal computer is displayed, in order to view the image, the direction in which the photographer observes must be changed from the tooth of the examinee to the display toward the display. In general, the position of the X-ray light-receiving body 25 or the X-ray device 50 is adjusted, and the photographing is performed plural times. Therefore, it is very troublesome for the photographer to frequently change the direction of the line of sight. According to the present embodiment, the photographer does not need to change the direction of the line of sight, but can simultaneously view a certain area of the teeth of the examinee and an area in which the image is displayed, so that the photographing result can be quickly confirmed. The electrical connection between the X-ray light-receiving body 25 and the personal computer, and the electrical connection between the display unit 40 and the personal computer are performed via the first and second cables 11 and 12 provided inside the support wrist 10, so that the cable can be prevented. In contact with the mouth of the examinee. Further, since the display surface 41 of the display unit 40 can be faced to the direction of the photographer by the rotation, and the subject side can be faced, the photographer and the examinee can easily observe the image obtained by the photographing. In particular, when viewing the photograph. As a result, while the state of the wrist support wrist 10 is simultaneously photographed, the examinee cannot move the face significantly, but according to the embodiment, the examinee does not have to move the face significantly. You can see the image of the photographic result. In addition, the present invention is different from the dental X-ray imaging apparatus of the prior art which is held by the occlusion of the teeth, and the photographer holds the 099117736 10 201103488 intraoral imaging assisting device 1 by holding the gripping portion 15, so that the child cannot be satisfactorily The person who is occluded can also securely hold the intraoral imaging assisting device 1 so that the X-ray irradiation direction, the position of the tooth T, and the positional relationship of the X-ray light-receiving body 25 are suitable for the bisecting method. Next, the second intraoral imaging assisting device 60 of the second embodiment will be described with reference to Figs. 4 and 5 . The same components as those in the first embodiment are denoted by the same reference numerals, and their description is omitted. Referring to Fig. 4, the second intraoral imaging assisting device 60 further includes an indicating portion 61. The instructing portion 61 extends from the image receiving body mounting portion 20 in a direction in which the image receiving surface 26 is formed at a right angle, and instructs the photographer to indicate the center of the image receiving surface 26. The indication portion 61 has an angle indicating wrist 62 that protrudes from the side surface of the image receiving body mounting portion 20, and a position indicating wrist 63 that extends from the end portion of the angle indicating wrist 62. The angle indicating arm 62 is composed of two corner posts, and protrudes at right angles from the center of the side surface of the image receiving body mounting portion 20, and is bent at a right angle and extends in a direction perpendicular to the image receiving surface 26. The direction of the right angle of the image receiving surface 26 is the direction in which the X-ray is incident. The position indicating wrist 63 is a corner post which extends at right angles from the extended end of the angle indicating wrist 62.

The length of the angle indicating wrist 62 is such that the position indicating wrist 63 is not inserted into the mouth when the image receiving body mounting portion 20 is inserted into the oral cavity. Since the wrist 61 is fixed to the image receiving body mounting portion 20, the wrist 61 is rotated relative to the wrist 10 as the image receiving body mounting portion 20 rotates. The indicator portion 61 is composed of a member permeable to X-rays. Therefore, it is not imaged by the X-ray image receiving body 25. Next, a means for photographing the tooth T by the second intraoral photographic assisting device 60 will be described with reference to Fig. 5 . When the examinee contains the second intraoral photographic assist device 60, one of the angle indicating wrist 62 and the position indicating wrist 63 are located outside the oral cavity. The photographer or the examinee holds the X-ray device 50 in such a manner that the X-ray irradiation direction, the position of the tooth T, and the position of the X-ray receiving body 25 are suitable for the bisecting method. At this time, the X-ray irradiation axis Y is parallel to the angle indicating shaft 62, and the X-ray device 50 is held so as to pass the position indicating the front end of the wrist 63. Then, the photographer irradiates the X-rays to perform photography. In this manner, the photographer can view a certain area of the subject T of the subject of the subject, while observing the image displayed on the display unit 40. In addition to being rotatable, the image receiving body mounting portion 20 is located in the oral cavity of the subject during imaging, so it is difficult for the photographer to know the correct position of the image receiving body mounting portion 20. However, according to the present embodiment, the photographer can grasp the position of the image receiving body mounting portion 20 by looking at the pointing portion 61. Further, in any of the embodiments, the shape of the support wrist 10 or the grip portion 15 may be, for example, a cylindrical shape or the like that can support the image receiving body mounting portion 20. Further, the first and second cables 11 and 12 may be provided outside the support wrist 10. Alternatively, the first cable 11 may be guided inside the support holder 10 via the inside of the image receiving unit mounting portion 20. Avoid contact between the mouth and the cable. Alternatively, the X-ray image receptor 25 may be integrally formed with the image receptor mounting portion 20. Further, the power supply to the X-ray image receiving unit 25 and the display unit 40 has been described as being performed from the personal computer via the first and second cables 11 and 12, but electric power may be supplied from another power source. For example, it is also possible to supply electric power from a battery provided on the support wrist 10. In this case, the transmission of the image signal from the X-ray image receiving body 25 to the personal computer, the transmission of the control signal from the personal computer to the X-ray image receiving body 25, and the control signal from the personal computer to the display unit 40 or The transmission of the video signal may be performed by wireless communication such as Bluetooth without passing through the first and second cables 11 and 12. Further, the image processing unit of the personal computer has been described as applying image processing to the image signal obtained by the X-ray image receiver. However, it is also possible to provide an image processing unit such as a DSP in the support wrist 10 and to photograph the auxiliary device in the oral cavity. 1 completes the form of photography, image processing and display. In addition, it is also possible to use the photographic subject tooth T or the like to engage the support wrist 10. 099117736 13 201103488 As shown in Fig. 2, the photographic subject tooth T or the like is directly contacted in the state of supporting the wrist 10, and the adjustment can be performed therebetween.
