Claims

[Scope of Claim for Utility Model Registration] A pedestal equipped with an optometric unit is mounted on the pedestal base so as to move within a predetermined range, and a safety device is provided to prevent the optometric unit from coming into contact with the eye to be examined. In the ophthalmological instrument, the safety device includes a stopper member extending in the front-rear direction on the pedestal base so as to be movable back and forth, and a contact portion on the pedestal side on the front side of the stopper member. A to-be-abutted portion is formed which abuts against and prevents the forward movement of the pedestal frame, and a to-be-latched portion that is continuous along the front-rear direction is formed on the stopper member, and furthermore, the stopper member is connected to the rearward direction. A spring member is provided that biases toward the stopper member, and a locking portion that engages and disengages from the locked portion of the stopper member is provided on the gantry base side, and the locking portion is connected to the locked portion of the stopper member. A biasing means for biasing in the direction of locking is provided, and the locking portion is moved from the locked portion of the stopper member against the biasing force of the biasing device upon detecting an operation of preparing for optometry measurement. An ophthalmological instrument characterized in that it is configured with a release means for detaching the device.
