Abstract
A stopper knob (108) is provided on the side surface of a base (101). If a joy stick (107) is tilted forward lowering the stopper knob (108), a platform frame (109) advances, and the main body of an instrument can be roughly aligned with a subject eye to be tested. If the alignment is completed, the stopper knob (108) is released. In the ophthalmic instrument of the present invention, automatic alignment which performs precise alignment on the subject eye is not started by only releasing the stopper knob (108). The ophthalmic instrument is provided with a microswitch (111). When the platform frame (109) is pulled on a tester's side by the joy stick (operating stick) (107) and the microswitch (111) engages with a protruding portion (112) fixed to the base (101), automatic alignment is started.
