Description of the Related Art In a conventional ophthalmologic apparatus, an ophthalmic image is electronically photographed and recorded on a recording medium such as a hard disk, a floppy disk, an optical disk, and the photographed data such as the name and ID number of a subject is taken. It is considered that an image is recorded on a recording medium by voice independently of the image capturing operation. Moreover, the shooting of the ophthalmic image and the recording of the shooting data are performed by separate switches.

[0003]

However, since the photographing of the ophthalmic image and the recording of the photographing data are performed in a dark room as described above, if the switches for photographing the ophthalmic image and recording the photographing data are different, the operation is not performed. It was a bad thing.

Therefore, the present invention provides an ophthalmologic apparatus having improved operability for photographing an ophthalmic image and recording the photographing data by providing a single switch for photographing the ophthalmic image and recording the photographing data. It is intended to be provided.

<Operation> Next, the operation of such a configuration will be described.

When photographing a slit image of the cornea of the eye of the subject, the head of the subject is supported on the chin rest 3 and the head of the subject is applied to the forehead rest 4. . In this state, the jaw rest 4 is moved up and down by a well-known up-and-down adjusting means (not shown) to coarsely move the eye to be inspected of the examinee up and down, and the movable table 11 is coarsely moved left and right to move the microscope unit 17. It is roughly adjusted to one eye of the examinee (the examinee's eye).

After this, the examiner 21 wears the contact lens 27.
While supporting with the left hand 26 against the cornea of the subject's eye, the right hand 2 while looking into the eyepieces 20, 20
5, the operation lever 22 is grasped, and the operation lever 22 is tilted forward, backward, leftward and rightward, and the movable table 11 is finely moved forward, backward, leftward and rightward to perform alignment in the front-rear direction and the left-right direction with respect to the eye to be inspected, and the operation lever 22 is rotated. Then lift 1
By finely moving 3 up and down, vertical alignment is performed.

The arithmetic control circuit 30 projects the illumination light for observation provided on the slit illumination light projection device 16 onto the eye to be inspected through the illumination light source control circuit 31 during this alignment. Then, after this alignment is completed, the imaging switch 23 protruding from the upper end of the operation lever 22 is pressed to perform imaging with the slit illumination light of the cornea of the eye to be inspected.

By this operation, when the arithmetic control circuit 30 receives the pressing operation signal of the photographing switch 23, it controls the operation of the slit illumination light projection device 16 via the illumination light source control circuit 31, and the slit illumination light projection device 16 is operated. The slit illumination light for slit imaging is projected from the eye to the subject's eye of the subject's head supported on the chin rest 3.

At this time, a quick return mirror (not shown) in the connecting tube 19a is arranged in the optical path of the microscope section 17 by a driving means (not shown) such as a solenoid, and the eye to be inspected enters the microscope section 17 from the cornea of the eye to be inspected. All the reflected light from the cornea is guided to the television camera 19 side, and a slit image (ophthalmologic image) of the cornea of the eye to be examined is formed on the television camera 19.

An electronic image signal is output from the television camera 19 (electronic image pickup means), and the electronic image signal is input to the arithmetic control circuit 30 as a digital ophthalmic image signal. The arithmetic and control circuit 30 includes an image processing means 3
The ophthalmic image information signal (ophthalmic image information data) of the eye to be inspected is constructed in the frame memory 33 as image data via 2.

On the other hand, when the examiner 21 continues to press the photographing switch 23 during this photographing, the arithmetic and control circuit 30 makes the voice information (voice comment) enterable from the microphone 24. In this state, the examiner 21 speaks subject data such as subject information and the state of the affected part of the subject eye to the microphone 24 while observing the subject's eye.
The voice signal from 4 is input to the arithmetic control circuit 30.

Then, the arithmetic control circuit 30 temporarily stores the input audio signal in a memory (not shown) or a recording medium of the information recording / reproducing device 34, and when the photographing switch 23 is released (pressing force). Is released), one frame of ophthalmic image data constructed in the frame memory 33 is recorded in the information recording / reproducing device 34, and is temporarily stored in the memory (not shown) or the recording medium of the information recording / reproducing device 34. The audio signal data thus saved is recorded on the recording medium of the information recording / reproducing device 34. At this time, the ophthalmologic image data and the audio signal data (captured data) are recorded so as to be associated with each other with associated ID numbers.

By pressing the reset switch 28,
You can re-enter the voice comment. It is also possible to add a comment to the already input voice. In this case, a comment can be easily added by providing a switch for adding a voice comment, for example.

<Other Example> The above-mentioned photographing switch 23 is
It can also be a foot switch (not shown).

Further, the photographing switch 23 may be a two-step push type switch. In this case, the shooting switch 2
3 by one-step pressing operation (the shooting switch 23 is half pressed), the electronic image signal is temporarily recorded as ophthalmic image data in the frame memory 33 (temporary recording medium), while the two-step pressing operation of the shooting switch 23 ( Shooting switch 2
3 is completely depressed), the examiner 21 puts the microphone 24
A voice comment (voice data) can be input from (voice input means). In this case, if only the one-step push operation is performed, only the ophthalmic image can be captured.

On the contrary, by pressing the photographing switch 23 one step (the photographing switch 23 is half pressed), the examiner 21 inputs a voice comment from the microphone 24 (voice input means), while the photographing switch 23 is pressed. It is also possible to temporarily record the electronic image signal in the frame memory 33 (temporary recording medium) as ophthalmologic image data by a two-step pressing operation (a state in which the photographing switch 23 is completely pressed down). In this case, only the voice comment can be recorded.

Then, the audio signal output from the microphone 24 is temporarily recorded in the memory (not shown) or the recording medium of the information recording / reproducing device 34 in association with the ophthalmic image data, and the photographing switch 23 is released. The ophthalmic image data of the frame memory 33 and the temporarily recorded audio signal data are recorded with ID numbers (corresponding to) associated with the recording medium of the information recording / reproducing apparatus 34.
