Scanning type ocular fundus imaging device

A scanning type ocular fundus imaging device comprising:

• a light projecting optical system that projects light from a light source on an ocular fundus of a subject eye via an objective lens optical system, the light being scanned as scanned illumination light using a scanning optical system;
• a light receiving optical system that receives reflected light from the ocular fundus via the objective lens optical system and the scanning optical system;
• a light receiving pinhole disposed in a vicinity of an ocular fundus conjugate position in the light receiving optical system;
• and
• a light shielding member disposed in the light receiving optical system to shield harmful reflected light from a lens plane of the objective lens optical system,
• wherein the light receiving optical system and the objective lens optical system are configured such that a light beam of scanned back-projection light is separated on the lens plane of the objective lens optical system from a light beam of the scanned illumination light, wherein the scanned back-projection light is scanned by the scanning optical system after exiting the light receiving pinhole and passing through a circumference of the light shielding member or after exiting a light receiving element and passing through a circumference of the light shielding member and the light receiving pinhole, wherein same scanning as that for the scanned back-projection light is performed for the scanned illumination light.
