Abstract: PURPOSE:To improve the accuracy of alignment and to execute the alignment of a large detection range by removing the influence of iris of an eye to be checked or reflected light from an eyelid at the time of the alignment. CONSTITUTION:A half mirror 1, lens 2 and television camera 3 are arranged on an optical axis in front of an eye E to be checked and the output of the television camera is connected to a signal processor 4. Then, an alignment light source 5 is arranged in the incident direction of the half mirror. Since a light flux from the light source for alignment forms a cornea reflected picture P in the cornea Ec, and when this cornea reflected picture is formed on an image pickup surface 3a of the television camera by the lens, the front eye part picture of the eye to be checked and the cornea reflected picture of the light source are projected on the image pickup surface. In such a case, reflection from the iris or eyelid of the eye to be checked is diffused reflection. However, since the reflection from the cornea is spherical reflection, the video signal of a scanning line S passing on a cornea reflected picture obtains an extremely strong cornea reflected part P'. Then, the two-dimensional position of this cornea reflected picture is detected and the alignment can be executed with the high accuracy over the wide range.
