Abstract

Provided is an ophthalmologic apparatus, which is configured to perform observation and photographing of an eye to be examined via an objective lens, and which allows the observation or the like of the eye to be examined irrespective of a posture of an examinee. The ophthalmologic apparatus includes: a main body part including an optical system and the objective lens that are configured to perform the observation and the photographing; a stand part configured to support the main body part with respect to an installation surface; a chin rest part configured to place a chin of an examinee thereon; and a forehead rest configured to bring a forehead of the examinee into abutment therewith. In the ophthalmologic apparatus, the chin rest part, the forehead rest, and the objective lens can be integrally changed in elevation angle with respect to the stand part.

First claim

What is claimed is:

1. An ophthalmologic apparatus, which is configured to perform observation and photographing of an eye to be examined via an objective lens, the ophthalmologic apparatus comprising:
a main body part comprising an optical system and the objective lens that are configured to perform the observation and the photographing;
a stand part configured to support the main body part with respect to an installation surface;
a chin rest part configured to place a chin of an examinee thereon; and
a forehead rest configured to bring a forehead of the examinee into abutment therewith,
wherein the chin rest part, the forehead rest, and the main body part are capable of integrally changing in elevation angle with respect to the stand part, while maintaining positional relationships of the chin rest part, the forehead rest, and the main body part.

2. An ophthalmologic apparatus according to claim 1 , further comprising a grip handle part which is fixed to the main body part, configured to be grasped by the examinee while maintaining a posture at a time of the observation and the photographing of the eye to be examined,
wherein the grip handle part, the chin rest part, the forehead rest, and the main body part are capable of integrally changing in the elevation angle with respect to the stand part, while maintaining positional relationships of the grip handle part, the chin rest part, the forehead rest, and the main body part.

3. An ophthalmologic apparatus according to claim 1 , further comprising:
a rack part supported by the stand part, configured to support the main body part slidably within a predetermined plane;
a display part configured to display an image obtained by one of the observation and the photographing of the eye to be examined;
an operation panel comprising an operation member configured to operate at least one operation portion of the display part and the main body part; and
a guide rail part located around the rack part, and configured to support the operation panel slidably to move the operation panel around the main body part.

4. An ophthalmologic apparatus according to claim 3 , wherein the guide rail part is configured to support the operation panel slidably and rotatably.

5. An ophthalmologic apparatus according to claim 1 , further comprising:
a frame part comprising the chin rest part and the forehead rest; and
a light-emitting part which is provided on the frame part configured to inform the examinee of a position of the frame part by emitting light.

6. An ophthalmologic apparatus according to claim 5 , further comprising a light-emitting part control part configured to sense one of a state in which the chin of the examinee is placed on the chin rest part and a state in which the forehead of the examinee is brought into abutment with the forehead rest, and turn off the light-emitting part in accordance with the sensing.

7. An ophthalmologic apparatus, which is configured to perform observation and photographing of an eye to be examined via an objective lens, the ophthalmologic apparatus comprising:
a main body part comprising an optical system and the objective lens that are configured to perform the observation and the photographing;
a stand part configured to support the main body part with respect to an installation surface;
a display part configured to display an image obtained by one of the observation and the photographing of the eye to be examined;
an operation panel comprising an operation member configured to operate at least one operation portion of the display part and the main body part; and
a guide rail part located around the main body part, and configured to support the operation panel slidably to change a positional relationship between the main body part and the operation panel by moving the operation panel around the main body part.

8. An ophthalmologic apparatus according to claim 7 , wherein the guide rail part is configured to support the operation panel slidably and rotatably.

9. An ophthalmologic apparatus, which is configured to perform observation and photographing of an eye to be examined via an objective lens, the ophthalmologic apparatus comprising:
a main body part comprising an optical system and the objective lens that are configured to perform the observation and the photographing;
a stand part configured to support the main body part with respect to an installation surface;
a chin rest part configured to place a chin of an examinee thereon;
a forehead rest configured to bring a forehead of the examinee into abutment therewith;
a frame part comprising the chin rest part and the forehead rest; and
a light-emitting part which is provided on the frame part, configured to inform the examinee of a position of the frame part by emitting light.

10. An ophthalmologic apparatus according to claim 9 , further comprising a light-emitting part control part configured to sense one of a state in which the chin of the examinee is placed on the chin rest part and a state in which the forehead of the examinee is brought into abutment with the forehead rest, and turn off the light-emitting part in accordance with the sensing.
