An image fiber for transmitting an image, a lens for forming an image on the end face of the image fiber, a light guide for illumination light for transmitting illumination light, etc. are provided.

。From the illumination light source 68, illumination light is directed through the illumination fiber 67 and "emanates from the tip of the intracavity monitoring probe 60." The illumination light is reflected by the reflecting mirror 61 and directed downward to illuminate the inside of the oral cavity. The light from the object passes through the reflecting mirror 6
1 is reflected, enters the lens on the end face of the probe 60, and forms an image on the end of the image fiber.

もできる。The image transmitted by the image fiber can be observed visually or with the naked eye by the receiver optical system within the image receiver adapter 63. Instead of viewing it directly, it is filmed using a television camera 64, recorded on a video tape recorder 65, and then displayed on a video monitor 66.
You can also do it.

]; It is extremely convenient to be able to record images on tape. It also allows multiple people to observe the affected area at the same time. You can also zoom in to 14 to see the detailed image.
しがしながら、このような画像観察装置を実際に使用し
てみると、いまひとつ欠点のある事か分った。However, when I actually used this type of image observation device, I realized that it had one drawback.
画像の左右が逆転する、という事である。This means that the left and right sides of the image are reversed.
反身４鏡６１８こよって、左右が逆転するのである。Due to the anti-body 4 mirror 618, the left and right sides are reversed.
ミラーを使うと、左右が反転するのは第５図に示すよう

る。When a mirror is used, it is natural that the left and right sides are reversed, as shown in Figure 5. In FIG. 5, +a+ represents the right-handed coordinates where the object exists. The optical axis is -4-. f
+3+ i; i is a coordinate system that represents the image reflected in the mirror. The direction of the optical axis is opposite. Since there is no dust in terms of
Ru.
ｊｌｓ ３図に示すように、ｆｆｆｉ小な器具の先の反
射鏡に映った像を観察する場合、このような左右の反転
はあまり気にならない。jls As shown in Figure 3, when observing the image reflected in the reflecting mirror at the end of a small fffi instrument, such horizontal reversal is not of much concern.
歯科医師は、反射鏡の像から実際のありさまを推測する
のに習熟しているし、画像が小さく、暗いので、反射鏡
で見ることのできる虚像が左右反対でも奇異な感じはな
い。ミラーに映る像が左右反対であるのはあたりまえの
事である。Dentists are skilled at inferring the actual state of the body from the mirror image, and since the image is small and dark, it is not unusual for the virtual image seen through the mirror to be reversed left and right. It is natural that the image reflected in the mirror is opposite to the left and right.
しかし、第４図に示すような犬がかりな画像観察装置を
用いて１口腔内を見る場合、左右反転した像が大きいビ
デオモニタの画商に１，１える、というのは奇妙なこと
である。左右反転しない像が画面内に現われて欲しいも
のである。However, when viewing the inside of one oral cavity using a dog-like image observation device as shown in FIG. 4, it is strange that the left-right inverted image appears on a large video monitor. I want an image that is not horizontally flipped to appear on the screen.
（つ）本発明の画像観察装置
本発明はこのような欠点を解決する事を目的とする。反
射鏡が１枚であるから、像の左右が反転するのである。(1) Image observation device of the present invention The present invention aims to solve these drawbacks. Since there is only one reflecting mirror, the left and right sides of the image are reversed.
反射回数か偶数回であれは、左右逆転現象は起らない。If the number of reflections is an even number, the left-right reversal phenomenon will not occur.
