By rotating a pinion (not shown) arranged in the protrusion 42c by a drive motor, the support column 42a is configured to move up and down.
[0038]
As the rotation drive unit 62, for example, as shown in FIG. 11, an upper end protruding portion 42b of the support column 42a is fitted into a pair of receiving portions 41a provided in a central portion of the lower surface of the table main body 41, and A pin 63 fixed to the receiving portion 41a side is penetrated through the upper end protruding portion 42b to be connected thereto, and a motor 66 fixed to the support column 42a side to a gear 64 integrated with the pin 63 disposed on the receiving portion 41a side. The table main body 41 is configured to rotate in the direction of the arrow shown in FIG. 9 by meshing the driving gear 67 attached to the motor and transmitting the rotational force of the motor 66 from the driving gear 67 to the gear 64 and the pin 63. ing. 9 and 11, reference numeral 68 denotes a cylindrical cover body.
[0039]
The main body locking means 45 includes, for example, as shown in FIG. 9, an electromagnet 71 disposed on the upper surface of the table main body 41 and a magnetic metal plate 72 fixed to the lower surface of the fixed base 113. The magnetic metal plate 72 is attracted by the magnetic force generated by the current supply, and the fixing base 113 is fixed at a predetermined position on the table main body 41.
[0040]
As shown in FIGS. 12 and 13, the force balance means 53 is disposed at the end of the table body 41 on the subject side, and applies a force corresponding to the inclination of the table body 41 to the subject M on the movable gantry 112. It is configured to be applied to the side end surface. That is, the cylindrical member 82 and the stepping motor 83 are fixedly supported by the support member 81 erected from the table body 41, and the pressing member 84 and the spring 85 which contact the end surface of the movable gantry 112 inside the cylinder 82. The adjusting body 86 is arranged in order, and the pinion 87 attached to the stepping motor 83 is meshed with a rack portion 86a provided below the adjusting body 86, and the position of the adjusting body 86 is displaced by the rotation of the stepping motor 83. Thus, the biasing force of the spring 85 against the pressing body 84 is adjusted, so that a different amount of force can be applied to the end surface of the movable gantry 112 according to the inclination of the table main body 41.
[0041]
For example, as shown in FIG. 11, the tilt sensor 51 has a rotary encoder 51a mounted on the outside of a gear 64 integrated with the pin 63, and detects a tilt state (angle) of the table body 41.
[0042]
As shown in an enlarged manner in FIG. 14, the remote controller 56 sets the raising key 91, the lowering key 92 of the table main body 41, the horizontal position of the table main body 41, and the forward tilt (tilt toward the subject M) position. A slide key 93 for continuous adjustment and a connection cable 94 to a control system are provided. In addition, Braille 95 (indicated by dots) meaning these may be attached to the vicinity of the ascending key 91, descending key 92, and slide key 93 so as to correspond to a person with low vision.
[0043]
Next, the operation of the optical table 1B for mounting an optometry apparatus according to the third embodiment will be described with reference to FIGS. 15 and 16, focusing on the case where the wheelchair mode is set by the mode switch 46.
[0044]
When the subject M in the wheelchair 100 reaches the vicinity of the table body 41 having a size that does not interfere with the wheels 101 and the elbow rest 102 and sets the wheelchair mode with the mode switch 46 (step S1), the examiner sets the wheelchair mode as described above. The raising key 91 of the remote controller 56 is operated by a required amount, whereby the vertical drive unit 61 of the driving means 44 raises the table body 41 by the amount of operation of the raising key 91 (for example, 10 cm) (step S2). The table body 41 is raised because the eye to be examined is slightly raised when the subject leans his head to the backrest of the chair as shown in FIG. This is because the optometry apparatus 111 cannot be set to the optometry appropriate position at the normal height position.
[0045]
Next, the examiner operates the slide key 93 of the remote controller 56 by a required amount, whereby the rotation drive unit 62 of the drive unit 44 moves the table body 41 from the horizontal position according to the operation amount of the slide key 93. The subject M is continuously inclined to the forward inclined position (for example, an inclination angle of 10 degrees) toward the subject M (step S3), and the eye height adjustment of the optometric apparatus 111 with respect to the subject's eye E of the subject M in the wheelchair 100 is performed. Then, as shown in FIG. 16, the optometry apparatus 111 is set to a proper optometry position for the subject M in the wheelchair 100.
[0046]
At this time, the rotary encoder 51a constituting the tilt sensor 51 detects the tilt angle of the table main body 41 and sends a detection signal to the control unit 50 (step S4). Based on the detection signal of the tilt sensor 51, the movable gantry 112 is fixed at a predetermined position on the table main body 41 to prevent the movement of the apparatus main body 110 at the time of optometry, thereby ensuring safety. Further, when the main body lock means 45 does not operate, the subsequent processing is interrupted, so that the safety for the subject M can be further improved.
[0047]
Next, the calculating means 52 calculates an applied force (for example, 800 g, etc.) necessary for balancing the power at the time of the moving operation in the inclined state of the movable base 112 corresponding to the inclination of the table main body 41 based on the detection signal (step). S5). The force balance means 53 rotates the stepping motor 83 under the control of the control unit 50, displaces the position of the adjusting body 86, and adjusts the urging force of the spring 85 against the pressing body 84. An amount of applied force (for example, 800 g or the like) is applied to the end surface of the movable gantry 112 according to the inclination of the main body 41 (step S6).
[0048]
As a result, the examiner can ensure the operability such as the coarse movement operation of the movable gantry 112 performed by the joystick 114 as completely the same as when the apparatus main body 110 is in the horizontal state. In this manner, it is possible to secure an appropriate optometry position of the optometry apparatus 111 for the eye E of the subject M in the wheelchair 100 and operability of the examiner, and perform the optometry process on the eye E. Yes (step S7).
[0049]
When the examiner accidentally operates the slide key 93 of the remote controller 56 by a required amount or more and the table main body 41 is tilted too much, the detection signal of the tilt sensor 51 becomes a predetermined angle (for example, 30 degrees or the like). ), The main body locking means 45 immediately energizes the electromagnet 71 and fixes the fixed base 113 at a predetermined position on the table main body 41 by the generated magnetic force. Sliding to the side can also be prevented.
[0050]
According to the third embodiment, the subject M places his / her own face on the chin rest 115 provided on the apparatus main body 110 without taking an unreasonable posture, and moves the subject's eye E to the subject of the optometry apparatus 111. It can face the side end face and undergo optometry (measurement of eye refractive power, etc.). Note that, even when the apparatus main body 110 does not include the chin rest 115, the subject M faces the subject E to the subject side end face of the optometry apparatus 111 without taking an unreasonable posture. Can be processed.
[0051]
In particular, by tilting the table body 41, and thus the apparatus body 110 forward, toward the subject M, the proper position of the optometry apparatus 111 with respect to the subject's eye E, and the optical path connecting the subject's eye E and the optometry apparatus 111, naturally Since the proper position is ensured by adjusting the figure as it is, the optometric apparatus 111 can be adjusted to the direction of the line of sight of the subject's eye E of the subject M. In this case, even in the case where the chin rest 115 is removed in advance, the optometry can be performed in an easy posture, the fatigue can be reduced, and the optometry can be performed without any pain.
[0052]
Incidentally, it is of course possible for the subject M to adjust the eye height position of the optometric apparatus 111 by operating the remote controller 56 in accordance with his own eye height position and the line of sight.
[0053]
Further, depending on the dimensions of the table main body 41, for example, a rack, a pinion mechanism, and a drive motor may be interposed between the bottom of the apparatus main body 110 and the table main body 41 to move the apparatus main body 110 itself on the table main body 41. It is also possible to secure an appropriate optometry position of the optometry apparatus 111 with respect to the eye E to be examined. In this case, operability can be improved by adding a key for moving the apparatus body 110 forward and backward to the remote controller 56.
[0054]
