The present invention relates to an oral camera, which allows the oral camera to obtain a stable and clear image while assembling a plurality of lenses accurately and stably so as to increase durability and to easily separate and replace only damaged parts when damaged. Was developed to； A camera body having a prism lens at the front end to bend the image of the viewing portion 90 degrees to be sent to the rear, and to transmit the image to the rear image sensor by a plurality of lenses therein, and the camera body mounted therein. In the oral cavity camera is configured to include a case having at least one operation button； The camera body is mounted to be spaced apart from the rear of the first doublet lens, the first doublet lens of the shape combined with the front of the prism lens of the front end, the front diffusion lens and the rear converging lens behind the prism lens A second doublet lens having a first converging lens and a rear double converging lens spaced apart from the rear of the first converging lens and coupled to a front converging lens and a rear converging lens； A third doublet lens having a shape in which a second converging lens, a rear converging lens is spaced apart from the rear of the second converging lens, and a front converging lens and a rear converging lens are combined； The image is transmitted to the rear image sensor through the fourth double-lens lens having a shape in which a converging lens and a rear diffuser lens are combined, and a third converging lens mounted to be spaced apart from the rear of the fourth doublet lens. That relates to oral camera features.본 발명은 구강 카메라에 관한 것으로서, 구강 카메라가 안정적이고 선명한 화상을 얻을 수 있도록 하면서 복수 개의 렌즈를 정확하고 안정적으로 안착하여 조립되도록 하여 내구성을 높이고 손상시 손상된 부분만 용이하게 분리하여 교체할 수 있도록 하기 위하여 개발된 것으로；전방 끝단에 프리즘 렌즈를 구비하여 관찰부의 화상을 90도 절곡시켜 후방으로 보내도록 하고 내부의 복수 개의 렌즈에 의하여 화상을 후방의 이미지센서로 전달시키도록 하는 카메라 본체와, 내부에 상기 카메라 본체를 장착하도록 하고 하나 이상의 조작버튼을 구비하는 케이스를 포함하여 구성되는 구강 카메라에 있어서；상기 카메라 본체는 전방 끝단의 프리즘 렌즈와, 상기 프리즘 렌즈 후방의 전방의 확산
