Latest Patents

Hanaoka's latest patents include an innovative optical sighting device. This device is designed to be installed on firearms and features an objective system that forms an inverted image of a target object on a first focal plane. Additionally, it incorporates an erect system that reverses the inverted image to create an erect image on a second focal plane. The erect system consists of lenses arranged between the two focal planes and a movable cylinder that holds these lenses. An adjustment mechanism allows for the tilting of the movable cylinder's axial direction, utilizing an advancing-retracting shaft and a double torsion spring to bias the cylinder.

Another significant patent is the reticle unit and optical sighting device. This invention includes a reticle with a sight line and an optical fiber that forms a dot by guiding light from a light source to the center of the sight line. The light incident portion of the optical fiber has a spherical surface, while the light-emitting portion features an inclined surface that reflects light. This design ensures that the light-emitting portion is positioned at the center of the sight line, enhancing accuracy for users.
