使用勝手が悪く、また、電子的に正像に戻すには、画像
処理が複雑、高価になる。As described above, the conventional intraoral observation camera has a reflection mirror (or prism).
This is a side-viewing technique, and there is a problem that the image is inverted. Of course, it is possible to use an optical (for example, Dove prism) or electronically (manipulate by memory) inversion to return to a normal image, but to return to a normal image optically, the structure is complicated and large. However, it becomes heavy and is not convenient to use as a handpiece, and in order to return to a normal image electronically, image processing becomes complicated and expensive.

る。The present invention has been made in view of the above-mentioned circumstances, and in particular, a reflection mirror is not used, in other words, an image which is not an inverted image can be obtained, and the head portion is downsized to make the hand. The object is to provide a dental oral cavity observation camera that is easy to use as a piece and can realize an image shape including the angle of the head portion.

The converted electric signal is transmitted to the image display device through a lead wire arranged in the handpiece. The invention of claim 2 provides a light guide in the handpiece. The light of the front surface of the objective lens is illuminated by the light emitted from the tip of the light guide, and the invention of claim 3 emits light from the light guide. It is characterized in that a light emitting portion for emitting light is provided in a ring shape around the objective lens.
