Ophthalmic apparatus
First Claim
1. An ophthalmic apparatus comprising:
- measuring means for inspecting or measuring a patient'"'"'s eye;
moving means for moving said measuring means relative to the patient'"'"'s eye;
designating means for designating an eye to be measured;
photographing means capable of photographing a face including both eyes of the patient;
first detecting means for detecting positional relationship between said measuring means and each of right and left eyes respectively based on an image signal from said photographing means;
alignment detecting means for detecting an alignment condition of said measuring means relative to the eye; and
leading means for leading said moving means so that said measuring means may be alined within the predetermined range relative to the eye based on results detected by said first detecting means and said alignment detecting means.

Abstract
An ophthalmic apparatus comprising a measuring device for inspecting or measuring a patient'"'"'s eye, a moving device for moving the measuring device relative to the patient'"'"'s eye, a designating device for designating an eye to be measured, photographing device capable of photographing a face including both eyes, first detecting device for detecting positional relationship between the measuring device and each of right and left eyes respectively based on an image signal from the photographing device, an alignment detecting device for detecting an alignment condition of the measuring device relative to the eye, and a leading device for leading the moving device so that the measuring device may be alined within the predetermined range relative to the eye based on results detected by the first detecting device and the alignment detecting device.

12. An ophthalmic apparatus comprising:
-
measuring means for inspecting or measuring a patient'"'"'s eye; moving means for moving said measuring means relative to the patient'"'"'s eye; designating means for designating an eye to be measured; photographing means capable of photographing a face including both eyes of the patient; first detecting means for detecting positional relationship between said measuring means and each of right and left eyes respectively based on an image signal from said photographing means; first controlling means for controlling said moving means so that said measuring means may be alined close to the position of the eye designated by said designating means based on results detected by said first detecting means; target projecting means for projecting an alignment target onto the eye under the condition that said measuring means is aligned close to the position of the eye; second detecting means for detecting an alignment condition of said measuring means relative to the eye by detecting an image of the target projected by said target image projecting means; second controlling means for further controlling said moving means so that said measuring means may be aligned to be capable of measuring based on results detected by said second detecting means; judging means for judging suitability of the alignment based on results detected by said second detecting means; and measurement starting signal generating means for generating a starting signal for measurement, which causes said measuring means to work at the time when it is judged by said judging means that the alignment is appropriate. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)
