The prism lens 122 is mounted on a portion where image information is incident, and refracts image information incident in a vertical direction to provide the image information in a horizontal direction. The prism lens 122 may have a triangular cross-sectional structure. The prism lens 122 may vertically refract image information entered through the first direction to form the first auto focus lens 124, 126 and the first image sensor 128, respectively. Accordingly, the first auto focus lens 124, the first image lens 126, and the first image sensor 128 may be disposed adjacent to each other in the horizontal direction.

The first autofocus lens 124 is disposed adjacent to the prism lens 122 and is disposed between the prism lens 122 and the first image lens 126 and through the prism lens 122 The focus of the image information to be entered is automatically adjusted.

The first auto-focus lens 124 may be a liquid lens or a voice coil lens (VCM) lens. The first autofocus lens 124 can obtain a focused image by simply positioning the first camera module 120 at a desired position in the patient's mouth without any special operation.

Accordingly, there is no need to extend the angle of view of the lens to an excessive extent, images with less distortion can be obtained, and time for adjusting the focus can be saved, thereby reducing the shooting time and increasing convenience for the patient and the user.
