[Industrial application field]

The present invention relates to an optometry apparatus that includes a table for attaching optometry instruments to the table, and an instrument to be examined on the table, in which the center position of the table is movable. [0011] The frame 11 having a disc shape has a plurality of carriers 15 having a supporting point 13 sufficiently distant from the center of the horizontal frame 11. A groove-like guide rail 15b is provided on the table 1 so that an instrument 7 such as a vision tester can be mounted (as shown in FIG. 2), and the movable table 5 can be [0014] In addition, a stopper (not shown) is provided for pulling out the optometry table 3. The instrument 7 is mounted on the mounting table so as to be rotatable on the vertical plane 11a. They are rotatably carried at a distance from each other on this circumference. :The horizontal carrier table 15aL1 is moved through the refrigerant table 5. 7 is fixed on the movable table 5 with bolts, etc.) The wheels 9 are guided by the carrier table 15a. In the old version, the instruments 7 were always arranged horizontally on the carrier 15, as shown in FIG. 2, so that the movable table 5 would not move. The shape of the case 33 is such that only the eye examination table 3 side can be opened. Further, the case 33 is suspended from a rope 41, and the rope 41 is wound around the case 33 to move it up and down in response to a counter driving force. [0027] How to use the optometry apparatus having such a configuration [0028] This method of use is almost the same as the ``th'' embodiment, and instead of rotating as in the embodiment, the desired instrument 7 is rotated vertically. To take out, the desired instrument 7 is aligned with the optometry table 3 and pulled out. If the device 7 is replaced with another device 7, the other device 7 may be closed. The roller 35 is guided by the column 31, and the balance is adjusted by 7 and 8 43 via two upper and lower pulleys 37 and 39. Two motors 17 are connected to the required pulley 39, which will be explained below. The difference is that the mounting table is

Now that we have completed 1, we have created a cross-sectional view 1 showing the relationship between the optometrist space and the final check by moving both the consultant examiner and the examinee across the table (perspective view of the consultant 1). ...Optometry table 3a...Rail 5...Movement table 7...Instrument

Claims (1)

[Claims] 1. An optometry apparatus comprising a table used for consulting and an instrument for optometry installed at a retracted position of the table except in front of the subject's eye, wherein the instrument is moved between the retracted position and the table via a moving means. An optometry device characterized in that it is provided movably between a central position and a central position.
