[0002]

2. Description of the Related Art There is known an optometry apparatus in which an optometry apparatus is arranged on an optometry table placed in front of a subject. As an instrument for optometry, an objective or subjective refraction measuring device or a device such as a slit lamp microscope is generally arranged. As a method of arranging the optometry apparatus on the optometry table, a method of attaching an arm to a column provided on the optometry table and suspending it from the arm is adopted in the subjective refraction measuring apparatus.

In the objective refraction measuring device,
A moving table that moves on the optometry table is provided, and a refraction measuring device is mounted on the moving table, and a retracted position and a use position (measurement position)
A method of moving between and is proposed. As a means for moving the moving table, a method is provided in which a guide rail is provided on the surface of the table, and the table is moved along the guide rail.
As described in Japanese Patent No. 152701 (invention name: optometry table), a method is known in which an extension plate is extended from a moving table to the back surface of the table and moved along a moving guide on the back surface of the table. On the optometry table, in addition to the instruments for optometry,
A control unit for operating an optometry instrument or the like is often placed. This control unit sends measurement data from an objective refraction measuring device to another device, or operates an objective refraction measuring device or an optotype presenting device.

[0004]

The store of an eyeglass store is generally small, and in order to effectively use the store space, it is necessary to keep the space for placing the optometry device as small as possible. But,
In an optometry device of a type in which an optometry device such as the above-described objective refracting device is mounted on a moving table, it is not possible to place another object on the optometry table within the range in which the device moves, so the control unit In order to place the above, the length of the optometry table needs to be at least the length in which the size of the control unit is added to the moving range of the instrument. Therefore, the conventional optometry apparatus has a drawback that the apparatus becomes large and a large installation space is required. Further, even in an optometry apparatus having a mechanism in which an arm is attached to a column provided on the optometry table and a subjective refraction measuring apparatus is hung on the arm, the visual field of the subject is ensured during the measurement. Since it is necessary, there is a drawback that the length of the optometry table must be increased just to put the control unit. In view of the above-mentioned drawbacks of the conventional apparatus, it is a technical object of the present invention to provide an optometry apparatus capable of efficiently performing an examination with a necessary minimum table length.

A tray arm 21 is fixed to the tray 20, the tray arm 21 goes around the side surface of the top plate 10, and a linear guide 22 on the back side of the top plate 22 is provided. Connected to. The linear guide 22 is movable along the guide groove 23. A roller 24 is arranged at the bottom of the tray 20, and the tray 20 moves in the longitudinal direction of the top plate 10 along the guide groove 23. The transmission cable and the power cable are held inside the tray arm 21, and the cables are not exposed to the outside.

As shown in FIG. 5, the control unit 3 is mounted on the top plate 10 via a mounting table 30. The structure of the mounting table 30 will be described with reference to FIGS. Figure 5
2 is a schematic view of the AA ′ cross section of FIG. 2, and FIG.
FIG. 7 is a schematic view of the section B-B ', and FIG. Reference numeral 31 denotes a moving plate on which the control unit 3 is placed, and the control unit 3 is provided at four corners of the moving plate 31.
An insertion hole 32 for inserting the foot is formed to stably hold the control unit 3. Moving plate 31
Two slide rails 33 are fixedly attached to the back surface of the. Reference numeral 34 denotes a slide rail receiver, and the slide rail receiver 34 is fixed to a fixed plate 35 attached to the top plate 10 by a metal fitting 36. The movable plate 31 is movable in the longitudinal direction of the top plate 10 with respect to the fixed plate 35 via a plurality of steel balls 37 arranged between the slide rail 33 and the slide rail receiver 34.

Reference numeral 38 denotes a spring. One end of the spring 38 is attached to the fixed plate 35 and the other end is attached to the moving plate 31, and the moving plate 31 is attached.
Is urged toward the automatic refraction measuring device 4 (rightward in FIG. 6). Reference numeral 39 denotes a limiting portion that limits the movement of the moving plate 31 in the right direction. The moving plate 31 includes the limiting portion 39 and the fixed plate 3.
It is usually located at the position where 5 contacts. Although the mounting table 30 is fixed to the control unit 3 in this embodiment,
By adding a rotation mechanism for rotating the control unit 3 on the moving plate 31 of the mounting table 30, the examiner can operate the control unit 3 while directly facing the control unit 3.

Next, the operation of the apparatus having the above-mentioned structure will be described focusing on the operation of the control unit. In order to perform the objective refraction test using the automatic refraction measuring device 4, the refraction measuring device 2 is rotated together with the arm 14 with respect to the pole 12, and the refraction measuring device 2 is rotated to the retracted position. The examiner moves the tray 20 on which the automatic refraction measuring device 4 is placed from the retracted position to the measurement position in front of the eye to be inspected by the linear guide 2

The mounting table 40 includes a holding plate 41 that holds the control unit 3, a holding plate arm 42 attached to the holding plate 41, and a shaft 43 that rotatably supports the holding plate arm 42 with respect to the top plate 10. To be done. Insertion holes for inserting the feet of the control unit 3 are formed at the four corners of the holding plate 41.

With the above-described structure of the mounting table 40, the holding plate arm 42 rotates about the shaft 43 and the holding plate 41 and the control unit 3 can be retracted, so that the objective refraction inspection apparatus 4 is moved to the measurement position. Even if the control unit 3 is moved, the control unit 3 retreats from the top 10 by being moved in advance or being pushed by the objective refraction inspection apparatus 4. Further, since the mounting table 40 has a degree of freedom in the rotation of the holding plate arm 42 as shown by the dotted line in FIG. 9, the examiner can freely select the position even during the inspection by the subjective refraction measuring device 2. hand,
The control unit 3 can be operated. Furthermore, when interviewing or filling out prescription rattan, etc., the control unit 3
It is possible to easily withdraw from the table surface simply by rotating the mounting table 40 without having to place it on another place, and the table surface can be widely utilized.

In the apparatus of the embodiment, the mounting table 40 is pushed by the automatic refraction inspection apparatus 4 or is manually rotated. However, a motor or the like may be attached to rotate the table 40 electrically. In this case, when the tray 20 on which the objective refraction inspecting device 4 is placed moves to a predetermined position, a detection means for detecting the position of the tray, such as the operation of a micro switch, is provided, and the motor is driven by the position of the tray 20. Then, the mounting table 40 can be retracted. Further, a single switch for rotating the mounting table 40 in the left-right direction may be arranged, or may be rotated in conjunction with the movement of the subjective eye examination apparatus 2 from the retracted position to the measurement position.
