Title:

OPHTHALMOLOGIC APPARATUS AND CONTROLLING METHOD THEREOF

Document Type and Number:

Japanese Patent JP2023001864

Kind Code:

A

Abstract:

To provide an ophthalmologic apparatus which can carry out alignment easily in a short time while preventing contact of an ocular characteristic acquisition part with a face of a subject during the alignment, and a controlling method thereof.SOLUTION: An ophthalmologic apparatus includes: a detection control part 60a which continues output of a detection signal by a relative position detection part (a Z alignment detection optical system 26) in performing alignment; a non-contact type sensor (a capacitance sensor 36) which can detect the approach of an ocular characteristic acquisition part to a face of a subject in a non-contact manner; a determination part 60b which continuously determines whether a detection value of the non-contact type sensor is greater than a threshold value or not in performing the alignment; and a risk avoiding operation control part (a stop control part 60c) which performs a risk avoiding operation when the relative position detection part cannot detect a relative position, and the determination part determines that the detection value is greater than the threshold value. When the relative position detection part detects the relative position, or the determination part determines that the detection value is not greater than the threshold value, the alignment is continued.SELECTED DRAWING: Figure 14
