<P>PROBLEM TO BE SOLVED: To provide an ophthalmologic device which can reduce burden of an examiner and can vertically move an observation unit or the like in a suitable manner without increasing in size. <P>SOLUTION: The ophthalmologic device provided with the observation unit for observing eyes of a subject includes: a vertically moving mechanism for vertically moving the observation unit provided with a vertically moving part which supports the observation unit and can vertically move, a rotating operation member which is rotated by the examiner and a conversion unit which converts rotation of the rotating operation member to vertical motions of the vertically moving part; a motor which transmits a driving force to the conversion unit through a transmission member; a rotation sensor which detects the rotative force or the rotation of the rotating operation member; and a control unit for controlling the torque of the motor on the basis of signals from the rotation sensor which controls the torque of the motor in proportion to the rotating force or the rotation detected by the rotation sensor. <P>COPYRIGHT: (C)2012,JPO&INPIT |
