[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an ophthalmologic apparatus in which an examiner can manually adjust a position shift between an eye to be examined and an apparatus main body by operating an operation member.
[0002]
[Prior art]
In an ophthalmologic apparatus such as an ocular refractive power measurement apparatus or a tonometer, it is necessary to align (position) the eye to be examined and the apparatus main body when performing the measurement.
[0003]
In order to perform this alignment adjustment, an operation member such as a joystick is provided for the ophthalmologic apparatus, and the position of the apparatus main body with respect to the eye to be examined is adjusted by operating (tilting, rotating, etc.) the operation member. .
[0004]
In this ophthalmic apparatus, when the joystick is largely tilted or rotated, the apparatus main body moves greatly, and when the joystick is rotated or tilted small, the apparatus main body moves small. The amount of movement of the apparatus main body is changed according to the amount to speed up the alignment adjustment (Japanese Patent Laid-Open No. 9-98951, etc.).
[0005]
[Problems to be solved by the invention]
However, an ophthalmologic apparatus such as a non-contact tonometer requires extremely high-precision alignment adjustment, and thus requires extremely fine adjustment near the alignment completion position. If a beginner who is unfamiliar with the operation performs this alignment adjustment, it may be difficult to perform delicate alignment adjustment because too much force is applied to the hand operating the operation member and the alignment completion position may be passed.
[0006]
In order to easily perform this delicate alignment adjustment, a configuration in which the amount of movement of the apparatus main body with respect to the amount of operation of the joystick is reduced in advance, for example, a configuration in which the amount of movement of the apparatus main body with respect to the amount of operation of the joystick can be halved. However, with such a configuration, when the amount of positional deviation of the apparatus main body with respect to the eye to be examined is extremely large, it is necessary to operate the joystick twice as much, which causes a problem that the operation becomes troublesome.
[0007]
The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide an ophthalmologic apparatus that can easily and quickly perform alignment adjustment even by an examiner unfamiliar with operation.
[0008]
[Means for Solving the Problems]
To achieve the above object, the ophthalmologic apparatus according to claim 1 adjusts the position of the apparatus main body by a manual operation of the apparatus main body that requires a predetermined alignment with the eye to be examined. An operation member that detects the operation amount of the operation member, a control unit that controls the amount of movement of the device body based on the output of the operation amount detection device, the eye to be examined, and the device body And an alignment state detecting means for detecting a positional deviation amount between the control unit and the control means when the positional deviation amount is within a predetermined range, the apparatus main body automatically aligns. An automatic alignment control mechanism for performing the automatic alignment control when the amount of positional deviation detected by the alignment state detection unit is outside a range in which automatic alignment control can be performed. Unit operation of operating members When the movement amount of the device main body per unit amount is set to be constant and the positional deviation amount is within a range where automatic alignment control can be performed, the device main body per unit operation amount of the operation member The amount of movement is set to be smaller than that in the case of being out of the range .
[0011]
The ophthalmic apparatus according to claim 2 , wherein the movement amount of the apparatus main body per unit operation amount of the operation member is a position when the displacement amount is within a range in which automatic alignment control can be performed. It is characterized in that the deviation amount becomes smaller as the deviation amount becomes smaller.
[0012]
The ophthalmic apparatus according to claim 3 , wherein the movement amount of the apparatus main body per unit operation amount of the operation member is constant when the displacement amount is within a range in which automatic alignment control can be performed. It is characterized by being kept at.
[0013]
The ophthalmologic apparatus according to claim 4 is provided with a stopping unit that stops the automatic alignment, and performs an approximate alignment between the eye to be examined and the operation main body by a manual operation using the operation member. Automatic alignment control is performed based on the amount of misalignment output from the alignment state detection means after completion of the alignment, and after the automatic alignment control is stopped by the stop means, The alignment adjustment can be performed manually using the operation member.
[0014]
By using such an ophthalmologic apparatus, when the amount of positional deviation between the eye to be examined and the apparatus main body is large, the apparatus main body can be moved greatly by operating the operation member, and when the amount of positional deviation is small Even if the operation amount is the same, the movement amount of the apparatus main body can be reduced, so that a delicate operation of the operation member is unnecessary, and alignment adjustment can be performed easily, quickly and with high accuracy.

[0047]
The control circuit 401 calculates alignment position deviation amounts ΔX, ΔY, ΔZ in the X, Y, and Z directions based on the video signal from the CCD 28 stored in the frame memory 403. When automatic alignment is performed, the control circuit 401 controls the alignment mechanism I based on the alignment position deviation amounts ΔX, ΔY, and ΔZ, and performs automatic alignment.
[0048]
On the other hand, when the alignment is performed manually, the control circuit 401 uses the alignment position deviation amounts ΔX, ΔY, ΔZ and the signals from the rotation amount detection unit 102D and the rotary encoders 503, 504, and the motor 104 of the alignment mechanism I. , 107, 112 are controlled.
[0049]
FIG. 5 is a graph showing the relationship between the X direction displacement amount ΔX of the lateral movement mechanism I2 and the motor rotation amount θ per unit tilt amount of the joystick 102 in the X direction when alignment adjustment is performed by manual alignment. is there.
[0050]
The control circuit 401 compares the radius X1 of the aiming scale S shown in FIG. 4 with the positional deviation amount ΔX. If the positional deviation amount ΔX is larger than the radius X1 of the aiming scale S, that is, the alignment target image T is the aiming scale. When it is outside S, the motor rotation amount θ per unit tilt amount of the joystick 102 is set to a constant value θmax as shown in FIG.
[0051]
On the other hand, when the displacement amount ΔX is smaller than the radius X1 of the aiming scale S, that is, when the alignment target image T is inside the aiming scale S, the motor rotation amount θ per unit tilt amount of the joystick 102 is set to the position. Decrease in proportion to the amount of deviation ΔX. That is, as the alignment target image T approaches the center of the aiming scale S, the motor rotation amount θ per unit tilt amount is controlled to be smaller than θmax. Therefore, even if the joystick 102 is operated by the same operation amount as when the alignment target image T is outside the aiming scale S, the lateral movement amount of the apparatus main body becomes small.
[0052]
The control circuit 401 controls the motor rotation amount θ per unit rotation amount of the joystick 102 according to the Y-direction positional deviation amount ΔY.
[0053]
The control circuit 401 compares the radius X1 of the aiming scale S and the positional deviation amount ΔY. If the alignment target image T is outside the aiming scale S, the motor rotation per unit rotation amount of the joystick 102 is detected. The quantity θ is a constant value θmax. On the other hand, when the alignment target image T is inside the aiming scale S, the alignment target image T is reduced by decreasing the motor rotation amount θ per unit rotation amount of the joystick 102 in proportion to the positional deviation amount ΔY. Is controlled so that the motor rotation amount θ per unit rotation amount becomes smaller than θmax as the distance approaches the center of the aiming scale S. Therefore, even when the joystick 102 is rotated by the same operation amount as when the alignment target image T is outside the aiming scale S, the amount of vertical movement of the apparatus main body is reduced.
[0054]
Further, the control circuit 401 controls the motor rotation amount θ per unit tilt amount of the joystick 102 according to the positional deviation amount ΔZ in the optical axis direction.
[0055]
The control circuit 401 compares the Z-direction misalignment amount ΔZ with respect to the appropriate position with the Z-direction range Z1 in which automatic alignment is possible. If the misalignment amount ΔZ is larger than the Z-direction range Z1, the joystick When the motor rotation amount θ per unit tilt amount of 102 is a constant value θmax and the positional deviation amount ΔZ is smaller than the Z-direction range Z1, the motor rotation amount θ per unit tilt amount of the joystick 102 is set to the positional deviation amount ΔZ. By reducing the proportional amount, the motor rotation amount θ per unit tilt amount is controlled to be smaller than θmax as the positional deviation amount ΔZ approaches the appropriate position. Therefore, even if the joystick 102 is operated by the same tilt amount as when the positional deviation amount ΔZ is larger than the Z-direction range Z1, the amount of movement of the apparatus main body in the front-rear direction is reduced.
[0056]
[Action]
Next, the operation of the ophthalmologic apparatus according to the embodiment of the present invention will be described.
[0057]
First, the examiner operates the joystick 102 while observing the anterior segment image displayed on the monitor 200 to perform rough adjustment of the focus of the anterior segment image and to perform rough alignment so that the pupil enters the scale S. Make adjustments. As the pupil is adjusted to enter the aiming scale S, the alignment target image T located outside the aiming scale S moves to the center of the aiming scale S.
[0058]
When the alignment target image T is outside the aiming scale S, as shown in FIG. 5, rough alignment can be performed with a predetermined motor rotation amount θmax (maximum value). The general alignment can be completed quickly.
[0059]
When the rough alignment is completed, automatic alignment is started, and the control circuit 401 controls the motors 104, 107, 112 of the alignment mechanism I. When alignment adjustment with sufficient accuracy is performed by automatic alignment, measurement of the eye to be examined is automatically started.
[0060]
When the alignment cannot be adjusted with sufficient accuracy by automatic alignment due to fixation eye movement of the eye to be examined, the automatic alignment is stopped after the automatic alignment is performed for a predetermined time, and a display urging the manual alignment by the examiner is displayed on the monitor 200. Is displayed.
[0061]
Manual alignment is performed by the examiner operating the joystick 102 to move the alignment target image T to the center of the aiming scale S.
[0062]
Since the amount of positional deviation is reduced by performing automatic alignment for a predetermined time, an extremely delicate joystick operation is required to perform high-precision alignment adjustment. As shown in FIG. 5, the amount of movement of the apparatus main body per unit operation of the joystick 102 when the amount of positional deviation is small is set to be smaller than that during rough alignment (that is, when the amount of positional deviation is large). Even when the joystick 102 is operated by the same operation amount as that for rough alignment, the amount of movement of the apparatus main body can be reduced, and high-precision alignment adjustment is easy without performing a delicate joystick 102 operation. And can be done quickly.
[0063]
[Modification]
In the embodiment of the present invention, as shown in FIG. 5, the motor rotation amount θ per unit tilt amount of the joystick 102 is controlled in proportion to the positional deviation amount of the alignment mechanism I, but as shown in FIG. As described above, when the alignment target image T is outside the aiming scale S (when the displacement amount ΔX is larger than X1), the motor rotation amount θ per unit tilt amount is uniformly set to θ2, and the alignment target image. When T is inside the aiming scale S (when the positional deviation amount ΔX is smaller than X1), the motor rotation amount θ is stepped so that the motor rotation amount θ per unit tilt amount is uniformly θ3. The shape may be changed.
[0064]
By changing the motor rotation amount θ stepwise, as in the above embodiment, the apparatus main body H can be moved largely with a slight tilt amount during the approximate alignment, so that the approximate alignment can be terminated quickly. In the case of performing fine alignment adjustment, the amount of movement of the apparatus main body can be reduced even when the joystick 102 is operated with the same operation amount as in the approximate alignment. High-precision alignment adjustment can be performed easily and quickly without any operation.
[0065]
Further, even when the relationship between the positional deviation amount and the motor rotation amount θ per unit tilt amount of the joystick 102 is expressed as a quadratic function, the same effect as the present invention can be obtained.
[0066]
Further, in the embodiment of the present invention, the manual alignment is performed after the automatic alignment is performed for a predetermined time. However, the present invention is not limited to this, and a stop switch for forcibly stopping the automatic alignment is provided. The automatic alignment may be forcibly stopped to enable manual alignment, or the automatic alignment operation may be eliminated and the alignment adjustment may be performed only by manual alignment throughout. Even in such a configuration, the same effect as that of the present invention can be obtained by controlling the relationship between the positional deviation amount and the motor rotation amount θ per unit tilt amount of the joystick 102 as shown in FIGS. Play.
[0067]
【The invention's effect】
As described above, according to the ophthalmologic apparatus according to the present invention, the apparatus main body can be largely moved by the operation member at the time of the rough alignment, so that the rough alignment can be quickly completed. Further, when the alignment adjustment is performed by manual alignment, even when the operation member is operated with the same operation amount as in the approximate alignment, the movement amount of the apparatus main body can be made smaller than in the approximate alignment. Therefore, it is not necessary to perform a delicate operation using the operation member, and even an examiner unfamiliar with the operation can easily and quickly perform the alignment adjustment with high accuracy.
