Half of the upper side of the light shielding cylinder 6 mounted on the front surface of the operation unit 11 of the camera body 1 is coated with an opaque paint (mainly black paint) or the like so as to prevent external light from passing therethrough. The light shielding part 6a covered by the light shielding plate and the lower half are comprised by the transparent see-through part 6b which can look inside.

The camera body 1 as described above is connected by a plurality of optical cables produced in the separately configured lighting device (2), the optical cable is an important function for illuminating the eye's iris by receiving light from the halogen lamp 21 In charge of.

The optical cables are composed of first to third optical cables 22a, 22b, and 22c in which two strands are formed in one pair, and each optical cable receives the light of the halogen lamp 21 to illuminate the iris. Is as follows.

In the front side of the halogen lamp 21 inside the lighting device 2 is provided with a light plate 24 is controlled by the small motor 23, the light receiving unit adjacent to the back surface of the light plate 24 It is inserted and installed in a row in the insertion hole formed in 22.

In addition, the lighting plate 24 is formed with a plurality of illumination holes 24a, 24b, 24c at each concentric position having different radii with respect to the center, and the illumination holes are different so as not to overlap each other. It is angled and consists of several groups. (See Figure 4)

Accordingly, the first to third optical cables installed in a line on the light receiving unit 22 adjacent to the rear surface of the lighting plate 24 sequentially receive halogen lamps 21 from the illuminators as the lighting plate 24 rotates. Will receive the light.

The first to third optical cables 22a, 22b, and 22c are directed by the lighting device 2 and connected to the camera body 1, wherein the first two optical cables 22a are hollow fixing rods. (52) and the inside of the heavy factory rod 51 is divided into both sides in the interior of the semi-circular lighting fixture (5) is installed so as to illuminate the left and right sides of the eye as shown in Figure 6, the second optical cable (22b) is shielded It extends to the inside of the cylinder 6 and is installed on the left and right sides of the zoom camera 3 (see FIG. 2), and the third optical cable 22c also extends to the inside of the light shielding cylinder 6 to extend the zoom camera 3. It is installed on the upper and lower sides.

In addition, the liquid crystal monitor 13 installed on the operation unit 11 of the camera body 1 is connected to a computer so that an image captured by the zoom camera 3 appears like a computer monitor.

On the other hand, the present invention is not limited to the number of installation of the optical cable to the first to third optical cable as in the above embodiment, it is possible to install the fourth to fifth optical cable between the second and third optical cable, this embodiment is The insertion hole of the optical cable is further extended to the light receiving unit 22, and the concave-shaped illuminating holes formed on the lighting plate 24 can be solved with a configuration that further increases so as not to overlap each other.

Referring to the operation of the embodiment of the present invention configured as described above are as follows.

The lighting fixtures 5 installed on the front surface of the operating unit 11 of the camera body 1 closely adhere so as to surround the eyeball, and simultaneously operate a switch (not shown) attached to the handle 12 to operate the servomotor ( When the 42 is operated, the traction cord 43 is wound around the driving pulley 42, and the eyeball extension 4 is angularly moved upwards from the axial point 44, such an angular motion. The eyeball expansion mechanism (4) is made in a state in contact with the upper skin of the eyeball to expand the eyeball so that the iris is well exposed.

The lighting plate 24 is operated by operating the switch on the handle 12 to light the halogen lamp 21 of the lighting device 2 and driving the small motor 23 at the same time as the eye is extended. When rotated, the illumination light of the halogen lamp 21 illuminates the eye through the optical cable installed in each insertion hole of the light receiving portion 22 through the illumination holes 24a, 24b, and 24c formed in the lighting plate 24. Since the above-described illuminators are formed spirally on concentric circles so as not to overlap each other, the first to third optical cables 22a, 22b, and 22c respectively receive illumination light sequentially to illuminate the eyeball in turn. will be.

That is, when the illumination hole 24a at the furthest position of the lighting plate 24 coincides with the first optical cable 22a provided at the bottom of the light receiving unit 22, the second to third optical cables 22b and 22c are provided. ) Is a state in which the illumination light is blocked, the illumination light of the halogen lamp 21 through the first optical cable 22c at both sides of the lighting fixtures 5 through the first optical cable 22c until the illumination hole 24a leaves the first optical cable 22a as described above. The left and right eyes of the eye are illuminated and the eye is photographed using a simultaneous zoom camera 3 to image on the monitor of the computer. Thus, when the left and right sides of the eye are illuminated using the first optical cable 22a, The depth of the iris, wrinkles, and the like can be precisely observed, and the lighting plate 24c is continuously rotated by the driving of the small motor 23, so that the illuminator 24c is the first optical cable ( If it is out of 22a), the next illuminator 24b will coincide with the second optical cable 22b. As the illumination light is received by the second optical cable 22b and illuminates the iris from the left and right sides of the simultaneous zoom camera 3, the entire structure of the iris is imaged on the monitor by the zoom camera 3 and the iris. Can be observed precisely. In addition, when the illuminator 24b is released from the second optical cable 22b by the continuous rotation operation of the lighting plate 24, the illuminator 24c at the smallest concentric position is coincident with the third optical cable 22c. The first optical cable extending up and down of the sub zoom camera 3 illuminates the iris at the furthest position, and at this time, the above-described third and second optical cables illuminate portions that cannot be clearly illuminated. will be.

As described above, the illumination holes 24a, 24b, and 24c in which the illumination light of the halogen lamp 21 is formed at different angles in the concentric circles in the configuration of rotating the illumination plate 24 slowly are operated as the illumination plate 24. Since the first and third optical cables 22a, 22b, and 22c are repeatedly formed on the light source, the first and third optical cables 22a, 22b, and 22c receive illumination light sequentially and repeatedly to repeatedly illuminate the iris from all sides. By taking pictures of the iris brightened by the illumination of the optical cables and displaying the image on a computer monitor, the entire organization of the iris can be observed more precisely to make an accurate diagnosis.

On the other hand, the first and the third optical cable can be individually illuminated by the two strands constituting it, in this case it is possible by configuring the illumination holes of the lighting plate 24 as in the embodiment of FIG. That is, a small illuminator that transmits the illumination light only to one strand of the optical cable on one side of the illuminator 24a, 24b, and 24c that enables the illumination light to be simultaneously illuminated by the two strands constituting the first and third optical cables. (a) When (b) is formed, the first and third optical cables can sequentially light one strand, and then two strands can simultaneously perform lighting operation, highlighting a part of the iris to be observed and inspected. In addition, the first and the third optical cable performs a lighting operation at the same time by forming a large light hole (24d) in the lighting plate 24 so that the illumination light can be received throughout the first and the third optical cable This allows you to capture and image the entire iris clearly.

In addition, the method of controlling the small motor 23 driving the lighting plate 24 selects an illuminator and an optical cable to continuously illuminate a part of the iris, thereby precisely observing and inspecting the iris. Diagnosis can be obtained.

In the embodiment of the present invention as described above, the liquid crystal monitor 13 installed on the main body of the camera 1 is configured such that an image shot by the zoom camera 3 appears like a computer monitor. It is possible to check the shooting state of the zoom camera with the liquid crystal monitor 13 while focusing the eyes on the use portion of 1), thereby reducing the effort of turning the eyes on the monitor of the computer.

According to the present invention as described above, the doctor can operate the camera using only one hand to perform the diagnosis of the iris conveniently, and repeatedly photographed by the zoom camera as an optical cable from all four sides of the iris when the iris is diagnosed. In addition to being able to present images on a computer monitor simultaneously, the effect is that the iris can be observed and diagnosed more precisely. There is an effect that the image can be immediately confirmed as a liquid crystal monitor, and since the camera body and the lighting device are connected by a flexible optical cable, it is a practical design that provides an advantage of easy handling of the camera.

The present invention is to enable the computer imagination of the eye iris from the various angles in the computer photography of the eye using the optical cable, so that the element of the iris can be clearly imaged.
