PROBLEM TO BE SOLVED: To provide an ophthalmologic apparatus capable of reducing positional deviations of a movable part corresponding to voids in drive mechanisms.SOLUTION: An ophthalmologic apparatus 1a comprises: a system control unit a movable part 3a on which an optometry unit 6 for measuring a subjects eye E is mounted, and which is movable relative to a fixed part 2 and an X-axis drive mechanism 33 and a Z-axis drive mechanism 32 for moving the movable part 3a relative to the fixed part 2. The system control unit measures the amounts of voids formed in the X-axis drive mechanism 33 and the Z-axis drive mechanism 32 in the move direction of a power transmission member, and controls the X-axis drive mechanism 33 and the Z-axis drive mechanism 32 on the basis of the measured amounts of voids.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2016,JPO&INPIT【課題】駆動機構における隙間に対応する可動部の位置ずれを低減することができる眼科装置を提供する。【解決手段】眼科装置1aは、システム制御部と、被検眼Eの測定を行う検眼部6が設けられ固定部2に対して移動可能な可動部3aと、可動部3aを固定部2に対して移動させるX軸駆動機構33およびZ軸駆動機構32とを有し、システム制御部は、X軸駆動機構33およびZ軸駆動機構32の動力伝達部材の運動方向に形成される隙間量を測定し、測定した隙間量に基づいてX軸駆動機構33とZ軸駆動機構32を制御する。【選択図】図1
