Field of the Invention The present invention relates to a dental imaging apparatus, and more particularly, to a dental imaging apparatus capable of acquiring skeleton information of a tooth outside an oral cavity, as well as three-dimensional movement and control of a photographing unit, Provided is a dental out-of-mouth imaging apparatus capable of rotating the rotation of the photographing unit 360 degrees or more freely, and restricting the rotation to about 400 degrees so as to prevent damage to the cable that softens the photographing unit.

The dental imaging device is for identifying various problems related to the patient's teeth and support structures or for observing diseases, symptoms, conditions and the like.

Such a dental imaging apparatus has been disclosed in Korean Patent Laid-Open No. 10-2009-0120909 entitled " Oral Exposure System x-ray Oral Imaging System ".

The oral cavity photographing apparatus comprises an x-ray image photographing apparatus for photographing an oral cavity x-ray image of a patient in contact with the outside of one side of the maxilla of a patient, An X-ray light source device for providing an X-ray light source to the X-ray imaging apparatus from the outside of one mandible of a patient; Ray imaging device and the X-ray light source device are arranged so that the optical axes of the X-ray imaging device and the X-ray light source device are aligned to face each other, and the X- Ray image taking device is positioned outside the maxillary bone of the patient to position the extracorporeal radiographing position of the tooth skeleton automatically when the patient is positioned outside the mandible of one side of the patient; And a support mount which is coupled to the support base through a JAVA LASIK support base and which is provided with a wheel at the bottom to adjust the position of the support base. , It is possible to visually confirm the patient's tooth information at the time of treatment, thereby improving the precision and safety of the operation.

However, in the conventional oral image taking apparatus, since the rotational movement of the support is limited to a maximum of 360 degrees, there is a problem that the oral cavity is not smoothly photographed due to the experience of a professional worker shooting the oral cavity.

This is because the JAVA LASIK support band exists as a connection body between the support and the mount. The JAVA LASIK support band is a bellows formed with corrugations, which can move in the bending mode but is not easy to rotate. Therefore, the rotation of the support is inevitably restricted, and the angle of view is not easily changed. Particularly, when the support is bent around the Xyla LASIK supporter, the support (the support with the X-ray imaging device and the X- There is also a problem that the stability of the supporting state is deteriorated due to its own weight.
