Title:
OPHTHALMOLOGIC APPARATUS AND CONTROL METHOD OF OPHTHALMOLOGIC APPARATUS
Document Type and Number:
Japanese Patent JP2023145008
Kind Code:
A
Abstract:
To provide an ophthalmologic apparatus capable of easily determining whether or not a movement limit position is set in a proper range, and to provide a control method of the ophthalmologic apparatus.SOLUTION: An ophthalmologic apparatus includes: a relative movement part (driving mechanism 13) for relatively moving an apparatus body (measurement head 14) with respect to an eye E to be examined; a movement limit position acquisition part (safety stopper position acquisition part 56) for acquiring a movement limit position (safety stopper position SP) of the apparatus body; a forward movement control part 58 for performing forward movement for moving the apparatus body to a front side; a non-contact type sensor (capacitance type sensor 36) capable of detecting, in a non-contact manner, approach of the apparatus body to the face of a subject; an estimation part 64 for estimating positional relationship in a front-back direction of the eye to be examined with respect to the apparatus body on the basis of a result of the detection by the non-contact type sensor while the forward movement is performed; and a determination part 66 for determining whether or not the movement limit position acquired by the movement limit position acquisition part is in a proper range on the basis of the positional relationship estimated by the estimation part.SELECTED DRAWING: Figure 7
