Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ophthalmologic apparatus for aligning an optometry section with an eye to be inspected to obtain predetermined eye information.

[0002]

2. Description of the Related Art Various types of conventional ophthalmic devices of this type are known. For example, Japanese Patent Application Laid-Open No. 1-277535 discloses an ophthalmic device for obtaining eye refractive power, intraocular pressure, fundus photography and the like. Has been done. When aligning the optometry unit with the subject's eye with this ophthalmologic device, the joystick, which is the operating rod, is tilted to the left and right and the front-back direction to manually drive the optometry unit in the same direction and rotate the joystick. By doing so, the optometry unit is manually driven in the vertical direction.

FIG. 8 shows an ophthalmologic apparatus for manually aligning an optometry section, in which a movable table 2 is installed on a fixed table 1 having a built-in power supply circuit and control circuit so as to be horizontally movable in the left-right and front-back directions. An optometry unit 3 including an optical system for optometry and a control circuit is installed on the movable table 2 via a vertical movement mechanism 4 so as to be vertically movable.

The movable table 2 is provided with a joystick 5 for manually driving the optometry unit 3 so as to be rotatable and tiltable, and a hard ball 6 at the lower end of the joystick 5 and an internal shaft can slide and rotate in the left-right direction. It is supported on the fixed base 1 by the horizontal guide unit 7. Further, a gear 8 coaxially provided on the joystick 5 and an internal shaft 9 of the vertical movement mechanism 4 are connected via a belt 10. As a result, the rotation of the joystick 5 rotates the inner shaft 9 of the vertical movement mechanism 4 via the belt 10 so that the optometry unit 3 can be driven in the vertical direction.

The electric circuit and control circuit built in the fixed base 1 and the electric circuit inside the optometry section 3 are connected by a bundle of electric wires 11. This bundle of electric wires 11 of the fixed base 1 and the movable base 2 is connected. It allows some movement in the horizontal plane. Note that the wire bundle 11 converts commercial power supplied to the inside of the fixed base 1 into necessary DC power to supply power to the optometry section 3, or transmits data obtained by the optometry section 3 to the main control circuit. ,
A control signal is transmitted from the main control circuit to the optometry unit 3.

On the other hand, in recent years, an ophthalmologic apparatus that electrically drives the optometry unit 3 in three-dimensional directions is disclosed in, for example, Japanese Patent Laid-Open No. 8-150115.
It is disclosed in the publication. This ophthalmologic apparatus is individually provided with driving means composed of a DC motor and a stepping motor for driving the optometry section 3 in the X, Y, and Z directions, and each driving means has a position for detecting a predetermined position. It is provided with a sensor, a position sensor for detecting the limit of the moving range, and the like. Therefore, the ophthalmologic apparatus that electrically drives the optometry unit 3 requires wiring for supplying electric power and control signals to each driving unit.

[0007]

However, in the ophthalmologic apparatus shown in FIG. 8, when a new function is added to the optometry section 3, various devices are added to the optometry section 3. In some cases, a new electric wire to be connected to the device is required, and the thickness of the electric wire bundle 11 may reach the allowable limit. In particular, an ophthalmologic apparatus that electrically drives the optometry unit 3 in three-dimensional directions includes three drive units for driving the optometry unit 3 in each of the X, Y, and Z directions, and for detecting these positions. Since the position sensor is provided, wiring for transmitting power and control signals to the drive unit and the position sensor is required, and the wire bundle 11 becomes thicker.

Further, even if the wires for power and control signals for the drive unit and the position sensor are branched from the wire bundle 11, not only the wire bundle 11 becomes thick, but also the required bending radius of curvature of the wire bundle 11 is increased. Also becomes larger, fixed base 1
May not fit inside. On the other hand, the wire bundle 1
When 1 is forcibly housed inside the fixed base 1, a stress difference or internal tension is generated in the electric wires passing inside and outside the bending radius of curvature, and the electric wires forming the electric wire bundle 11 are easily cut.

Further, as shown in FIG. 9, in the conventional ophthalmologic apparatus, the vertical movement mechanism 4 includes an X-direction drive unit, a Z-direction drive unit, and a Y-direction drive unit.
The directional driving unit is configured such that the X-direction driving unit and the Z-direction driving unit are connected by the wire bundle 15, the Z-direction driving unit and the Y-direction driving unit are connected by the wire bundle 16, and the Y-direction driving unit and the optometry unit 3 Are connected by a wire bundle 17. For this reason, the electric power and the control signal are divided into three stages and transmitted, so that the electrical contact resistance increases and radiation noise occurs, and the operation of the optometry unit 3 tends to become unstable.

An object of the present invention is to solve the above-mentioned problems and to provide an ophthalmologic apparatus which prevents damage to the transmission member and improves reliability.

[0011]

In order to achieve the above object, the present invention according to claim 1 provides an optometry means for obtaining eye information of an eye to be examined, and a horizontal 1 for aligning the optometry means to the subject's eye. Drive means for driving in the X direction, the Y direction in the vertical direction, and the Z direction in the horizontal multi-direction, and a transmission member for transmitting a data signal obtained by the optometry means or a control signal for controlling the optometry means via the driving means. In the arranged ophthalmologic apparatus, the drive means drives the optometry means in the X direction, an X direction drive means that drives the optometry means in the Y direction, and drives the optometry means in the Z direction. Z direction driving means, the transmission member has a Y direction transmission part for transmitting electric power or a control signal to the Y direction driving means, and the transmission part is movably arranged in the internal space of the X direction driving means.

FIG. 3 is a block diagram of an electric block circuit for controlling the optometry apparatus. The control board 61 is arranged inside the optometry section 23 and is connected to various devices inside the optometry section 23. In the case of an eye refraction measuring device or a tonometer, the LED 62 uses a light source for both measurement and alignment, an anterior segment illumination light source, a fixation lamp light source, and the like. Then, in the case of a fundus camera, instead of the LED 62, an infrared observation light source, a strobe light source,
A fixation light source is used.

In the case of the eye refraction measuring device, the sensor 63 is a position sensor for detecting whether or not the fixation guidance actuator is at a predetermined position, and in the case of the tonometer, when the eye E to be inspected is too close. As a proximity sensor to warn of danger, in the case of a fundus camera, it should be a position sensor that detects the movement of the reflective member for split illumination or the movement of the zoom lens for shooting, or the insertion of an optical member for alignment detection. It is used as a position sensor to detect the evacuation.

The actuator 64 is used for guiding the fixation in the case of the eye refracting device, for inserting or retracting the diaphragm in the case of the corneal curvature measuring device, and in the case of the tonometer, air is supplied to the eye E to be examined.
In the case of a fundus camera, it is used as a solenoid for driving the lens to drive the reflecting member for split illumination and to switch the observation of the anterior segment.

3 is directly connected to the I / O 66, and the actuator 64 is connected to the I / O 66 via the driver 67. Also,
The other sensor 68 is connected to the I / O 66 via an AD converter 69. The other sensor 68 is a temperature sensor used when correcting a measurement value that varies depending on the ambient temperature in the case of a corneal curvature measuring device, and detects the pressure of the air chamber for calculating the measurement value in the case of a tonometer. As a pressure sensor used to do this, or the optometry unit 23 uses the eye E
It is used as a proximity sensor that is used to detect the approach to and prevent their collision.

The CCD 70 is connected to the above-mentioned control board 28 via a video cable 71 and transmits a video signal to the control board 28. A plurality of CCDs 70 may be provided. In the case of an eye refraction / corneal curvature measuring device, a sensor for detecting fundus reflected light for measuring eye refractive power, a sensor for observing the anterior segment of the eye, and a ring-shaped light source for the cornea. Is used as a sensor for projecting light and detecting the reflected light.

The I / O 66 not only receives input of data signals of various devices of the optometry unit 23, but also has a role of allocating control signals from the control board 28 to the respective devices via the main electric wire 72. . In this case, the main electric wire 72 not only transmits a data signal and a control signal, but is also used as a power supply line and a common ground line for various devices.

On the other hand, on the control board 28, an X-direction drive motor 39 and a position sensor 73 for detecting the limit of the moving range of the left-right moving frame 38 in the X-direction and the initial position are connected to the motor driver 74. . Similarly, the control board 28

It is connected to the motor driver 74 via an electric wire 78.

The trackball 24, the roller 25, and the switch panel 26 are connected to the MPU 80 via the I / O 79, and the display means 27 is connected to the video cable 71. The chin rest driving motor 81 and the printer 82 are connected to the I / O 84 via a driver 83. As a result, the chin rest driving motor 81 operates based on the control signal from the driver 83 to move up and down the chin rest on which the subject's chin is placed. Further, the printer 82 uses the information obtained by the optometry unit 23, for example, the eye refraction measurement value, the eye pressure measurement value,
It is designed to print images such as fundus images.

The video signal detected by the CCD 70 is directly output to the display means 27 as a video via the video cable 71, and the video signal is AD-converted by the IC 85.
And a path for AD conversion and input to the frame memory 86. In addition, MPU80 is ROM87
The system program stored in is loaded and a series of operations for optometry is performed. The control board 28 is connected to a power supply circuit 88 for supplying electric energy obtained from a commercial power supply to various devices and distributing the power.

Here, when an electric wire of the same material and the same structure is largely bent, that is, when the bending curvature of the electric wire is made small, the number of bendings until the electric wire is cut is reduced, but the same material and the same structure are used. When the electric wire is bent slightly, that is, when the bending curvature of the electric wire is increased, the number of times of bending until the electric wire is cut can be increased.
On the other hand, since the height of the chin rest and the height of the electric optical stand are adjusted, the movement range of the optometry unit 23 in the Y direction is about 30 mm. Further, since the depth of carving of the face of the examinee differs depending on the examinee, the optometry unit 23
The range of movement in the Z direction is about 40 mm, which can cope with variations in the forehead of the subject and the distance between the jaw and the cornea in the axial direction. However, since it is necessary to measure both eyes E of the subject, the moving range in the X direction is about 90 mm.

Therefore, in this embodiment, the video cable 71, the main electric wire 72, and the electric wires 76 and 78 for electrically connecting the control board 28 and the control board 61 are formed by integrally covering a plurality of flat conductors. The tape-shaped electric wire is a flat cable 89. The flat cable 89 is located inside the drive unit 22, and has a first bent portion 89a, a flat portion 89b, and a second bent portion 89c sequentially from the control board 28 side. In this case, the first bent portion 89a includes the video cable 71, the main electric wire 72, and the electric wires 76 and 78.
The flat portion 89b and the second bent portion 89c include the video cable 71 and the main electric wire 72.

The first bent portion 89a slightly extends upward from the control board 28, and then horizontally bends between the guide shaft 35 of the X-direction drive unit 31 and the feed screw 36,
The side surface of the Y-direction drive motor 52 makes one round. The flat portion 89b extends flatly from the end portion of the first bent portion 89a, which makes one round of the Y-direction drive motor 52, to the vicinity of the control board 61, and the second bent portion 89c has the flat portion 89b.
Is bent in a U-shape from the upper end portion of and is connected to the control board 61.

Both ends of the first bent portion 89a are fixed, and both ends of the second bent portion 89c are also fixed so that the length of the first bent portion 89a and the length of the second bent portion 89c do not change. I have to. On the other hand, the first bent portion 89a is configured to be movable in the X direction and the Z direction between the guide shaft 35 of the X direction drive unit 31 and the feed screw 36.
The flat cable 89 is fixed by a flexible member so that partial stress is not generated even when the flat cable 89 is bent.

In this optometry apparatus, when the examinee places his or her chin on the chin rest of the face receiving portion, the examiner operates the chin rest driving switch of the switch panel 26 to adjust the height of the eye E to the face. Align with the mark on the receiving part. Further, the eye E to be inspected is the display means 27.
If not, the trackball 24 and the roller 25 are operated to move the optometry section 23 so that the eye E to be inspected is displayed on the display means 27. At this time, data corresponding to the operation amounts of the track ball 24 and the roller 25 is I / O 79.
To the MPU 80, and the MPU 80 calculates the drive amounts in the X, Y, and Z directions of the optometry unit 23 based on the input data, and the X direction drive motor 39, the Z direction drive motor 45, Y The direction drive motors 52 are controlled respectively.

Next, the examiner confirms that the eye E to be inspected is displayed on the display means 27, and thereafter operates the measurement start switch of the switch panel 26. As a result, auto-alignment starts, and the video signal detected by the CCD 70 is input to the image AD conversion IC 85 via the video cable 71, converted into image data, and stored in the frame memory 86.

Then, the MPU 80 extracts a corneal reflection image emitted from the light source of the optometry section 23 and reflected by the cornea of the eye E to be examined from the image data, and calculates the amount of deviation from the proper position in the X, Y, and Z directions. Then, the amount of movement of the optometry unit 23 in the X, Y, and Z directions is calculated based on these displacement amounts, and the motor driver 7
X direction drive motor 39, Z direction drive motor 4
5, output to the Y-direction drive motor 52. During this time, MP
The U80 sequentially takes in image signals for alignment detection from the CCD 70 and repeatedly confirms whether or not the optometry unit 23 is aligned at an appropriate position. And the optometry unit 2
When 3 is aligned in the proper position, the optometry operation is automatically started.

When measuring the refraction value, the MPU 80 detects the reflected light of the light source projected on the fundus of the eye with another CCD, and the frame memory 8 through the image AD conversion IC 85.
Store in 6. Then, the MPU 80 calculates the eyeball diopter, performs the fog operation of the fixation target by the action of the fixation fixation, stores the fundus reflected light again, and finally calculates the spherical power, the astigmatic power, and the astigmatic axis angle.

When the intraocular pressure value is measured, the solenoid is controlled to drive the piston after the alignment is completed, and the air in the air chamber is ejected from the nozzle toward the eye E to be inspected. Then, the cornea reflected light when the eye E is deformed is received, and the pressure value of the air chamber at the time of maximum light reception is converted into an intraocular pressure value.

In the case of the fundus camera, after the alignment is completed, the lens for switching from the anterior segment observation to the fundus observation and the split reflecting member are driven, the split image of the fundus reflection is detected by the CCD 70, and the shift amount of the focus lens is detected. Is calculated. Next, the focus lens is driven according to the amount of this shift, and the focus of the fundus image detected by the CCD 70 is automatically adjusted. After the focus is properly adjusted, the strobe light source automatically emits light and the fundus image is transferred to the CCD 70.
To the frame memory 86 via the image AD conversion IC 85
, And the fundus image is stored in the frame memory 86.

In this embodiment, the X-direction drive unit 31 having the largest space and the Z having the next largest space.
Since the first bending portion 89a of the flat cable 89 is arranged in the direction drive unit 32, the bending radius of curvature of the flat cable 89 can be increased. Therefore, the stress generated in the flat cable 89 can be reduced, and the flat cable 89 can be prevented from being cut.

Further, since a flat cable 89 formed by integrally covering a plurality of flat conductors is used instead of bundling a plurality of conventional electric wires formed by protecting a core wire with a coating, stress is not generated at the bent portion. Does not occur, that is, no stress is generated in a certain electric wire, a tensile tension is generated in a certain electric wire, and a problem that the electric wires are entangled with each other, and the assembling work is facilitated.

The flat cable 89 is fixed to the fixed portion 21.
Since the control board 28 on the side and the control board 61 in the optometry unit 23 are directly connected without being divided, the electrical contact resistance of the flat cable 89 does not increase, and the radiation noise does not occur. The optometry unit 23 can be stably driven, and the reliability can be improved.

In the above-described embodiment, the inner end of the first bent portion 89a of the flat cable 89 is fixed to the Y-direction drive motor 52 by making a round of the side surface of the Y-direction drive motor 52. Even if the 1-bent portion 89a is fixed to another portion of the Y-direction drive motor 52 so as to have another shape, the stress generated in the flat cable 89 can be suppressed.

For example, as shown in FIG. 4, the first bent portion 89
a is fixed so as not to surround the Y-direction drive motor 52 at all, or as shown in FIG.
5 and the Y-direction drive motor 52 so as to be positioned between them, or as shown in FIG.
The Y-direction drive motor 52 is fixed so as to make a half-circle from the 5 side, or the first bent portion 89a is fixed so that the Y-direction drive motor 52 is made to make a substantially half-circle from the feed screw 36 side as shown in FIG. You can also
