Although the image from stereoscopic vision observation possible multiple points of view being acquisition possible, it assures the narrow diameter conversion of the interposition section. In the light sensing portion and the said light sensing portion which the long interposition section (5) are provided inside, illumination light (L1 and L2) the two-dimensional the Drive section which is scanned (4) and illumination light (L1 and L2) the reflected light being in common illumination light (L1 and L2) the said illumination light (L1 and L2) two cores which are irradiated to the position where it slips mutually in the direction which is crossed in the optical axis (21a and 22a) the optical fiber which it possesses (2) and the core (21a and 22a) by vibrating to one body in the biaxial direction which the said optical fiber (2) crosses in the extended shaft, absorb lightDepending, each illumination light (L1 and L2) the image generation department which generates the image of the scan field (9) with the scanning-type endoscope device which it has it offers (1) from the reflected light which is detected the sensing station which detects the reflected light which absorbs light separately (8) with, the said sensing station (8) by.立体視観察可能な複数の視点からの画像を取得可能でありながら挿入部の細径化を図る。細長い挿入部(5)内に設けられ、照明光(L1,L2)を該照明光(L1,L2)の光軸に交差する方向に互いにずれた位置に照射する2つのコア(21a,22a)を有する光ファイバ(2)と、該光ファイバ(2)の長軸に交差する2軸方向にコア(21a,22a)を一体的に振動させることにより照明光(L1,L2)を2次元走査する駆動部(4)と、照明光(L1,L2)の戻り光を共通して受光する受光部と、該受光部によって受光された戻り光を別々に検出する検出部(8)と、該検出部(8)によって検出された戻り光から各照明光(L1,L2)の走査領域の画像を生成する画像生成部(9)とを備える走査型内視鏡装置(1)を提供する。
