Abstract
An ophthalmic apparatus in which a tilt angle of an operating rod corresponds to a position of an inspection unit adapted to inspect an eye to be examined, and a movable range of the inspection unit is wider than a tilt able range of the operating rod, the apparatus comprising: a detection unit adapted to detect the tilt angle of the operating rod by detecting an electrical signal generated by tilting the operating rod; a calculation unit adapted to calculate a position of the inspection unit which corresponds to the tilt angle; a moving unit adapted to move the inspection unit to a position calculated by the calculation unit; and a switching unit adapted to switch between interruption and resumption of calculation processing performed by the calculation unit.
