Patent ID: 7715023

Claim:
A jig mounting apparatus for mounting a jig on an eyeglass lens, comprising: a detection optical system including an aperture stop, a light source configured to irradiate an optical light flux via the aperture stop toward a surface of the eyeglass lens, a reference marker being formed on the surface, a focusing optical system configured to focus the optical flux irradiated from the light source, and an imagine device provided on a position optically approximately conjugate with said aperture stop and configured to focus the optical flux focused by the focusing optical system on a space portion alone an optical axis direction from the surface of said eyeglass lens and to detect the reference marker of the eyeglass lens based on the light flux focused on the space portion; a determining device configured to determine a mounting point based on the reference marker detected by the detection optical system; and a mounting device configured to mount the jig on a surface of eyeglass lens by positioning a mounting center of the jig at the mounting point.
