| description | PROBLEM TO BE SOLVED: To image a specimen image in a desired range, while suppressing enlargement of a biological information acquisition device, concerning the biological information acquisition device including an optical system for image transfer. SOLUTION: The biological information acquisition device 55 includes a light guide 90 for guiding a light flux through a plurality of light reflecting surfaces, and an imaging part 85 for imaging a subject image by receiving the light flux output from the light guide 90. The light guide 90 includes an input surface for inputting the subject image on the front, includes a first light reflecting surface arranged oppositely to the input surface on the back side, and further includes a second light reflecting surface extending in the thickness direction of the light guide. By adopting the light guide 90, the specimen image is obtained in the desired range, while suppressing enlargement of the biological information acquisition device 55. COPYRIGHT: (C)2010,JPO&INPIT |
