正する。Amendment 3.1.31. The brief description of the drawing is amended as follows. From line 11 on page 12 of the specification to line 15 on the same page, the phrase “Figure 2 A...shown” has been replaced with “Figure 2
The figure shows a light reception output curve, where A shows an alignment light reception output curve corresponding to the alignment data stored in the memory, B shows a pressure curve and a light reception output curve stored in the memory, to correct.

Claims

[Claims for Utility Model Registration] The main body of the device is aligned with respect to the eye to be examined using an alignment optical system, and the discharge of fluid is automatically started based on the light reception output of the alignment light receiving element, and the fluid is transferred to the eye to be examined. In a non-contact tonometer that measures intraocular pressure by spraying on the cornea, a memory is provided that stores changes in the light reception output of the alignment light receiving element from immediately before the start of corneal deformation due to the release of the fluid to immediately after the end of the corneal deformation as alignment data. An alignment check device comprising: an alignment check device for checking an alignment state from immediately before the start of corneal deformation to immediately after the end of corneal deformation based on the alignment data stored in the memory;
