按，内視鏡係一種裝置，其運用在管體前端裝設鏡頭， 並將該管體穿入欲檢查的裳置内部之後，再讓鏡頭所擷取 到的影像在顯示器上顯現，供使用者瞭解裝置内的狀況。 由於内視鏡的使用特性特別適合運用在管路的檢查，所以 應用内視鏡檢查家庭排水管線、社區下水道、熱交換器中 的管路或觸媒轉換器内管線…也逐漸被重視。…、° 由上述内容可知内視鏡的使用環境為管路内部，若使 用常見的内視鏡’則因為只有在管體前端裝賴影模組， 所以使用H朗管體前方的纽。若是㈣者運用此 種内視鏡觀察管體侧面影像，則會因為觀察角度的影響產 生影像失真的問題。對此’已經有如我國專利公告第 ^麵號專利「_内視鏡裝置」的 第 ，用第二影像掏取模組14負責操取_第二視 =的::用者可秦察管體側面影像避免產生 惟’前述多視角内視鏡裝置在 度下僅能觀察管路部分管路内壁情況，=探 定深度下全周管路内壁情況，勢必需要轉動内視= 201235000 L才錢察全周管路内壁情況。不過，因為内視鏡使用 ==體是連結在一起的，所以轉動内視鏡管體也 同寺而要轉_㈣，這會讓使用者在 不便性。除此之外，瞢妒咖如α 體内。卩的裱境並非穩定，在管體無 法轉動的情況下，㈣法_全辟路㈣情況。 對於上述問題已經有英國公告第咖3424198號專利 所提供之管路檢查裝置，可以檢查全周管路内壁。惟，隨 ==像解析度不斷地提升，造成鏡頭的設計複雜度 以及鏡聽#增加。若是以此專_結構㈣，當 側視攝影鏡頭15_崎度增加㈣要 時 造成管檢查裝置的管體直徑過大，増加使用上的不便與= 【發明内容】 本發明之主要目的在於提供一種變換側視 視内視鏡’其毋需轉動管斷可觀察全辭路㈣情況。 ，本發明之另一目的在於提供一種變換側視之 視内視鏡，其可在提升㈣鏡影像解析度的 ^ 加管體直徑長度。 避免巧 緣是’為了達成前述目的，依據本發明所提供之 變換侧視位置之側視内視鏡，包含有：一管體，具有一产 形的視窗；-驅轉裝置，係設置在該管體内；—反射元件化 係在該管㈣受_驅轉裝置驅使轉動，該反_件且有 -反射面，該反射面對應該視窗轉動讓該管體侧方周圍的 影像透過該視窗抵達該反射面；-側視攝韻組係以與 201235000 該管體同軸向的方式設於該管體内且對應該反射面，擷取 該反射面反射的影像；以及一侧視光源，設於該管體内， 用以產生光線照射該管體側方環境。 藉由將3亥管體伸入欲觀察管路内，操作該驅轉裝置帶 動S玄反射元件轉動，即可將該視窗外全周管路内壁情況經 由該反射面反射至該側視攝影模組，供該側視攝影模組擷 取影像。同時該側視攝影模組，係與該管體u同軸向的方 式擷取該反射面反射的影像，而非直接擷取該管體侧方的 景;^像，所以就算該側視攝影模組長度增加亦不會造成内視 鏡的管體直徑增加’維持使用上的便利。 【實施方式】 為了詳細說明本發明之技術特點所在，茲舉以下之一 較佳實施例並配合圖式說明如後，其中：Press, the endoscope is a device that uses a lens attached to the front end of the tube body and inserts the tube into the interior of the skirt to be inspected, and then the image captured by the lens is displayed on the display for use. Learn about the conditions inside the device. Since the use characteristics of the endoscopes are particularly suitable for use in pipeline inspections, the use of endoscopes to inspect domestic drainage lines, community sewers, pipes in heat exchangers or pipelines in catalytic converters has also received increasing attention. ..., ° It can be seen from the above that the use environment of the endoscope is inside the pipeline. If a common endoscope is used, the button in front of the H-tube is used because only the front end of the tube is attached to the shadow module. If the (4) person uses this type of endoscope to observe the side image of the tube, the image distortion will occur due to the influence of the observation angle. In this case, the second image capturing module 14 is responsible for the operation of the second image capturing module 14 as follows: The side image avoids the occurrence of the above-mentioned multi-angle endoscope device. Only the inner wall of the pipeline part can be observed under the degree of the degree. = The inner wall of the pipeline is full under the depth of the probe. It is necessary to rotate the internal view = 201235000 L The inner wall of the pipeline throughout the week. However, because the endoscopes use the == body to be joined together, rotating the endoscope tube also turns to the same temple as _(4), which makes the user inconvenient. In addition, 瞢妒 如 α α α α α. The embarrassing situation is not stable. In the case that the pipe body cannot be rotated, (4) the law _ full road (four) situation. For the above problems, the pipeline inspection device provided by the British Patent No. 3,424,198 has been able to inspect the inner wall of the pipeline. However, as the == image resolution continues to increase, resulting in the complexity of the lens design and the increase in the mirror #. If this is a special structure (4), when the side view photographic lens 15_saturation increases (4), the diameter of the pipe body of the pipe inspection device is too large, and the inconvenience in use and the use of the invention are as follows. [Inventive] The main object of the present invention is to provide a Transforming the side-viewing endoscopes, they need to turn the tube to observe the situation of the whole road (4). Another object of the present invention is to provide a side view mirror that converts the side view, which can increase the length of the tube body by increasing the resolution of the (four) mirror image. A side view mirror for changing a side view position according to the present invention is included in the present invention, comprising: a tube body having a shaped window; and a driving device disposed at the side The inside of the tube; the reflective element is driven in the tube (4) by the _ drive device, the reverse member has a reflective surface that is rotated by the window so that the image around the side of the tube passes through the window Arriving at the reflecting surface; - the side view camera group is disposed in the tube body in the same axial direction as the 201235000 tube body, corresponding to the reflecting surface, capturing the image reflected by the reflecting surface; and the side view light source, In the tube body, the light is used to illuminate the lateral environment of the tube body. By extending the 3H tube into the pipeline to be observed, and operating the driving device to drive the S-reflector to rotate, the inner wall of the entire circumference of the window can be reflected to the side-view camera through the reflecting surface. Group for the side view camera module to capture images. At the same time, the side view photographic module captures the image reflected by the reflecting surface in the same axial direction as the tube body u, instead of directly capturing the side view of the tube body, so even if the side view photographic mode An increase in the length of the group does not result in an increase in the diameter of the tube of the endoscope' to maintain ease of use.
