<P>PROBLEM TO BE SOLVED: To provide an eye examination apparatus capable of reliably preventing the front part of a measurement instrument body from coming into contact with the face of a subject when moving the measurement instrument body, and also rapidly performing measurement. <P>SOLUTION: The eye examination apparatus includes: a measurement instrument body position detecting means 25 for detecting the present position of the measurement instrument body 12 with respect to the original point position (0, 0); a contour line position coordinate data storage part 26 for storing contour line position coordinate data Q1, Q2, Q1', Q2' with respect to the original point position; a feature point position coordinate data storage part 26 for storing the portion of the face of the subject, on which the front part of the measurement instrument body 12 is predicted to be abutted, as feature point position coordinate data N', C2', C1' by defining the portion as the feature point and defining the original point as reference; a determining means 25 for determining, based on the contour line position coordinate data and the feature point position coordinate data, whether the front part of the measurement instrument body abuts onto the face of the subject when keeping driving as it is, based on a driving command; and a control means 25 for controlling the measurement instrument body, so as to avoid the face of the subject, based on the determination result of the determining means 25, regardless of the driving command. <P>COPYRIGHT: (C)2011,JPO&INPIT |
