Hereinafter, with reference to the accompanying drawings Figures 1 to 9 will be described a preferred embodiment of the present invention.

First, two support shafts 3 are installed at an upper end of the support plate 1 to be placed on a flat surface, such as a desk, and a face support 4 for facing the forehead of the patient at the top of the support shaft 3. Is formed, the middle portion of the support shaft (3) is provided with a face rest provided with a height adjustable jaw support (2).

The face support is provided with a distance adjusting means 5 and the case member (6).

The distance adjusting means (5) forms a support tube (51) that can be multi-stepped on each side of the front surface of the face support (4), the end of the support tube 51 is formed with a ring-shaped coupling ring (52) It is configured so that the support shaft to be installed in the coupling ring 52 can be fixedly coupled.

That is, the case member 6 fixed to the coupling ring 52 is moved back and forth by the indentation operation of the support tube 51 to be in close contact with the face of the patient against the face support 4. .

The case member 6 is a place where the optical fiber and the lamp which substantially emit light are installed, and a separate connection portion 64 is formed on the upper portion of the case 61 of the cylindrical body, and the light shielding portion 62 is made of rubber material at the tip portion. ) Is formed.

The case 61 is fixedly supported by the connecting portion 64 to the support shaft 63 which is fixedly coupled to the coupling ring 52, so that the connecting portion 64 can move left and right on the support shaft 63. The cylindrical casing 61 is configured to move both the left and right eyes of the patient by a predetermined distance and to illuminate both the left and right eyes of the patient.

On the other hand, the dimming case 65 for the optical fiber and the lamp is installed on both sides of the front end portion of the case 61, a plurality of couplings for inserting a plurality of optical fibers having a diameter of 2mm or less in the dimming case (65a, 65b) The holes 66 are arranged in a vertical direction so that the light radiated from the optical fiber is irradiated in a rectangular shape, and a plurality of lamp holes 67 for combining two lamps up and down on one side of the coupling hole 66. Is formed.

In addition, since the dimming case 65 is coupled to both side wall surfaces of the case 61 by hinge shafts 68 protruding from the upper and lower ends thereof, the dimming case 65 may be rotated by a predetermined angle to adjust the dimming angle.

On the other hand, there is provided a dimming means (7) for controlling the lighting of the optical fiber and the lamp installed in the case member (6),

The dimming means 7 includes a power supply unit 71 for outputting a predetermined voltage, first and third relay switches RL1 to RL3 for switching the output voltage of the power supply unit, and the first and third relay switches ( Halogen lamp 73 which is lighted by the output voltage of the 1st and 3rd voltage variable parts 72a-72c which depressurizes or boosts the output voltage through RL1-RL3, and the said 1st voltage variable part 72a. )Wow. The optical fiber 74 is installed in the coupling hole 66 of the dimming cases 65a and 65b and illuminates the iris and the white part of the eye with the light source of the halogen lamp 73, and the lamps of the dimming cases 65a and 65b. Lamps 75a to 75d respectively installed in the holes 67 and illuminated by the output voltages of the second and third voltage variable parts 72b and 72c to illuminate the upper and lower iris and the white part of the eye, and the optical fiber or lamp Key portion 76 for instructing selective lighting and illumination control, and optical fiber or lamps installed in the first and second dimming cases 65a and 65b are selectively turned on according to the key input, It is composed of a control unit 77 for controlling each unit to be adjusted.

The key portion 76 is provided with a selection key for selecting an optical fiber 74 or lamps 75a to 75d, an illumination control key for illuminance control, and the front of the lamps 75a to 75d for light condensing. It is desirable to form a lens.

Among the lamps 75a to 75d, two lamps 75a and 75c are installed in the dimming case 65a on one side, and the other two lamps 75b and 75d are installed in the dimming case 65b on the other side. By selectively illuminating the upper and lower iris and the white part of the eyeball.

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

First, the patient's chin for iris imaging is placed on the chin rest (2), and then the forehead portion is brought into close contact with the face support (4). In this state, the cylindrical case 61 is pushed or pulled to support the distance adjusting means (5). As the tube 51 emerges, the cylindrical case 61 is in close contact with the eye area of the patient, and the light shielding part 62 formed at the front of the case 61 is in close contact with the eye area, so that external light enters the case 61. It will not flow.

In this state, when the user inputs a specific key of the key portion 76 to select the dimming of the optical fiber 74, and operates the illuminance adjustment key to select the iris observation mode, the control of the control unit 77 that received this command In operation, the first relay switch RL1 is turned on to pass the output voltage of the power supply unit 71, and the voltage variable unit 72a reduces the output voltage of the power supply unit 71 and supplies it to the halogen lamp 73. The halogen lamp 73 emits light in a slightly dark state.

Accordingly, the light irradiated from the halogen lamp 73 is moved through the optical fiber 74 to be reflected on the eye of the patient.

Since the optical fiber 74 is installed in the coupling hole 66 of the dimming cases 65a and 65b provided on both sides of the case 61, the light irradiated from the optical fiber 74 is applied to the iris and the white part of the eye, respectively. When the iris is clearly illuminated and the irradiated light is not precisely matched to the iris and the white, the illumination cases 65a and 65b are rotated at an angle to set accurately.

When the light is irradiated accurately to the iris and the white part by the above operation, the iris photographing mode is set by operating the illuminance adjusting key of the key part 76 after putting the separate photographing device 80 to the rear end of the cylindrical case 61. do.

When the iris photographing mode is set, the control unit 77 controls the voltage variable unit 72a to increase the output voltage, and the halogen lamp 73 receiving the output voltage of the voltage variable unit 72a receives very bright light. Will be emitted.

Accordingly, since the light reflected from the optical fiber 74 is also brightened, the iris photographing device in close contact with the rear end of the case 61 blocks external light and illuminates the iris and the white part by the bright light of the optical fiber 74. In this state, the iris can be taken clearly.

On the other hand, when an abnormality occurs in the halogen lamp 73 and the illumination of the optical fiber 74 cannot be implemented, lamps 75a to 75d are used.

That is, when a user selects a lamp by operating a specific key of the key unit 76, the first relay switch RL1 is turned off by the control operation of the controller 77, and the second and third relay switches RL2 are turned off. As the RL3 is turned on, the output voltage of the power supply unit 71 is supplied to the lamps installed in the dimming cases 65a and 65b through the voltage variable parts 72b and 72c.

At this time, the control unit 77 first turns on the second relay switch RL2 to turn on the lamps 75a and 75b respectively provided at the upper ends of the dimming cases 65a and 65b on both sides. The upper iris and the white part are illuminated. Then, when the user inputs a separate key again, the controller 77 turns off the second relay switch RL2 and at the same time turns on the third relay switch RL3 to turn on. The lamps 75c and 75d respectively provided at the bottom of the dimming case are turned on, so that the lower iris and white part of the eyeball are illuminated.

In such a state, when the iris is to be photographed using the lamp light, when the specific photographing key provided in the key part 76 is inputted, the control unit 77 controls the voltage variable parts 72b and 72c to supply the power source 71. By increasing the output voltage of the light, the light irradiated from the lamps 75a to 75d becomes very bright, so that the iris camera 80 can take a very clear iris.

Since the condenser lens is installed at the front end of the lamp, the light irradiated from the lamp is concentrated in one place to more effectively illuminate the iris.

In addition, a prism may be provided at the tip of the lamp to concentrate the light of the lamp in one place.

8 and 9 illustrate another embodiment of the present invention,

The flexible tube 91 is installed on both sides of the upper surface of the cylindrical case 61 and the angle is freely adjusted, and is formed of a 'b' is coupled to the front end of the flexible tube 91 and the optical fiber 74 is inserted into the end thereof. A plurality of coupling holes 92 are configured to further illuminate the iris at a variety of angles by freely adjusting the angle of the flexible tube 91 formed in a straight line in the vertical direction.

An optical fiber 74 is inserted into the flexible tube 91, and the optical fiber 74 is inserted into a plurality of coupling holes 92 formed at the end of the dimming case 93 and irradiated from the optical fiber 74. The light forms a vertical rectangle.

According to another embodiment as described above, the light can be irradiated from the side of the iris by the free angle control of the flexible tube 91 and the dimming case 93 formed in a 'b' shape so that the reflected light is hardly generated when the iris is photographed. You can expect the effect.

Accordingly, not only the iris can be photographed from various angles using the flexible tube 91 but also the iris can be illuminated even without blocking external light.

As described above, the present invention constitutes a dimmer device equipped with an optical fiber and a lamp for illuminating the eyeball inside the case formed of a cylindrical body on the front of the face support that supports the patient's face when photographing the eye's iris, and the user's height By configuring a separate control means for adjusting the illumination of the optical fiber and the lamp according to the operation, by illuminating the patient's eye with the concentrated light in the state that the external light is shielded to obtain a clearer iris image, A flexible tube that can be freely adjusted is installed on both sides of the upper surface of the case, and a dimming case formed by the letter 'A' at the end of the flexible tube and a coupling hole formed in a straight line in the vertical direction is installed to prevent various irradiation without blocking external light. This is an iris photography dimmer that allows you to shoot the iris at an angle.
