DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a subjective optometric apparatus for performing a subjective test by presenting a visual target to a subject facing the subject.

[0002]

2. Description of the Related Art In a subjective optometry apparatus for inspecting visual functions such as visual acuity while a face of a measurer confronts and interacts with a person to be measured, a optometry table equipped with an optometer is conventionally arranged, and is placed on the table. A control section for controlling the optometry, such as switches necessary for measurement, was placed. When operating such an optometric apparatus, it is necessary for the measurer to proceed with the measurement while paying sufficient attention to the attitude and state of the subject. However, in recent years, the number of examination items has increased, and the optometry apparatus has become multifunctional. Therefore, a measurer who is not skilled in operation cannot perform measurement without looking at a complicated operation procedure table.

Therefore, it has been considered that the optometry information is displayed on a display device such as a CRT to present not only the measurement result but also the measurement procedure to the measurer. As this kind of technique that has been already disclosed, for example, there is an invention of an optometry apparatus with a display disclosed in JP-A-64-62117. According to the present invention, a CRT display that displays optometry information in a pattern of characters and graphic patterns is placed on an optometry table, and a control unit in which a plurality of operation switches such as a lens switch, a mode changeover switch, and an optotype switch are arranged is used. We operate on table for use.

[0004]

However, in the above-mentioned prior art, since the CRT display and the control unit are arranged on the optometry table, the measurer processes the measurement data using this table. In addition, when creating a predetermined document such as a medical record or a medical chart, the work is hindered. In addition, there is a case where a CRT display is not necessary for a conversation with a subject at the time of optometry,
It is also necessary to show the display contents to the subject. Therefore, there is a problem that the operation of rotating the display each time is troublesome.

Further, when an objective optometry apparatus is arranged on an optometry table and a combination of the two is performed, the table area is further reduced and the sense of oppression to the subject is increased. It is also considered that the objective optometer is slid on the table and moved to the front of the measurer in use, but for this purpose, the control unit must be temporarily removed, for example, in a drawer of the table. . As described above, the conventional optometry apparatus has various problems in performing an efficient optometry operation.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances , and has improved the utilization of the table upper surface , and has been described in detail.
It is an object of the present invention to provide a subjective optometry apparatus that presents measurement information to a subject.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the subjective optometry apparatus of the present invention will be described below with reference to the drawings. FIG. 1 is a plan view showing a subjective optometer for measuring refractive power for distance and near vision.
In this apparatus, a person to be measured is located in front of the front side of the figure, and faces the person to be measured with the optometry table 1 interposed therebetween to perform optometry. A circular window 3 is provided at a substantially central portion of the optometry table 1.
Is provided. The window 3 is covered with a flat glass plate, and the rectangular display 2 is disposed below the window. Further, the display 2 incorporated in the optometry table 1 is capable of rotating by 180 ° in each of the left and right directions about the center position of the window 3 as an axis. Present measurement information.

FIG. 2 is a front view of the subjective optometry apparatus of FIG. The measurement head 4 is movably disposed by a head arm 5 at a predetermined position between the subject and the subject. The head arm 5 is rotatably attached to a support column 6 provided at the back right of the optometry table 1. At the time of measurement, the measurement head 4 is located at the position shown in FIG. The vertical position can be adjusted according to In the subjective measurement, for example, a near bar is attached to the measuring head 4 and a predetermined target plate is presented to the subject. The strut 6 has a built-in control device necessary for subjective measurement. On the right side of the optometry table 1, an objective refractometer (Automa
A tic refractometer (AR) 7 is slidably installed in the left-right direction. The objective measurement by the objective refractometer 7 is usually performed prior to the subjective measurement,
At that time, the measuring head 4 is rotated to the storage position on the side surface of the objective refraction measuring device 7, and the objective refraction measuring device 7 is moved to the position above the center window 3 of the optometry table 1. In addition,
A column 8 supporting the optometry table 1 houses the base of the subjective optometry apparatus.

In this optometry apparatus, not only a display device such as a CRT conventionally disposed on a table surface, but also a control unit such as a keyboard is removed from the table. Since the display 2 is built in the optometry table 1, the surface of the optometry table 1 can be used widely and effectively.

FIG. 1 shows an input wireless mouse 9 and a light receiving unit 10 on the optometry table 1. Each of the wireless mice 9 is a simple one having about 1 to 3 operation keys, and an infrared signal output from the mouse is received by the light receiving unit 10. In addition to the wireless mouse 9, the optometry apparatus is provided with a patient key (not shown) as input means used by the subject. Using these, the person to be measured and the person to be measured, respectively,
While viewing the display 2, various command signals are sent to the optometry apparatus main body. An input screen required for the subjective test is presented on the display 2, and the measurer uses the wireless mouse 9 to interactively interact with the input screen, for example, a command necessary for controlling the lens system of the measuring head 4 and a command for switching the target. You can choose.

Therefore, when inspecting visual functions such as visual acuity while interacting with the subject using the subjective optometric apparatus, the measurer uses the wireless mouse 9 while presenting an optotype to the subject. By looking at the measurement result displayed on the display 2, it is possible to accurately input the work items necessary for the next measurement. In addition, by rotating the display 2 by 180 ° as necessary, the subject can receive an explanation of the measurement situation from the subject while viewing the measurement results shown on the same table. Here, it is preferable that the display 2 has a flat panel type display screen, for example, an electroluminescence (EL) substrate, a liquid crystal, a plasma display, or the like, in order to be incorporated in the optometry table 1.

Next, a rotation mechanism for driving the display 2 to rotate will be described. FIG. 3 is a partial cross-sectional view showing a rotation mechanism built in the optometry table 1. FIG. 4 is a plan view of the rotation mechanism of FIG. 3 as viewed from above, and FIG. 3 shows a cross section taken along a line indicated by a dashed line III-III in FIG.

The drive motor 11 is fixed to the surface of a table face plate 12 formed integrally with the optometry table 1 in the window 3. A drive pulley 13 is connected to a drive shaft 11a protruding from the drive motor 11 to the back side of the table face plate 12. In addition, a circular hole 15 having a diameter substantially equal to the length of the long side of the rectangular EL display screen 14 is formed in the table face plate 12. Guide rollers 16 are fixed at three places around the hole 15 on the surface of the table face plate 12, and a guide ring 17 is supported by these guide rollers 16 so as to be rotatable around an axis 17a. This guide ring 17
A driven pulley 18 is integrally screwed to the lower surface of the table, and is connected by a wire 19 so that the driven pulley 18 penetrates the hole 15 and interlocks with the driving pulley 13 on the back surface of the table face plate 12. .

As can be understood from the plan view shown in FIG. 4, both ends 19a and 19b of the wire 19 are fixed to the peripheral end faces of the driven pulley 18 which are separated from each other by 180 °. The wire 19 is wrapped around the driven pulley 18 by a half turn clockwise from one end 19a thereof, then is further wrapped around the driven pulley 18 again via the driving pulley 13 by a half turn, and reaches the other end 19b. Thus, the wire 19
Are fixed so that the driven pulley 18 rotates only 180 ° in the left-right direction regardless of the rotation of the driving pulley 13. An EL display unit 21 is fixedly mounted on a guide ring 17 which rotates integrally with the driven pulley 18 via a mounting plate 20. The EL display unit 21 has an EL display screen 14 attached to the upper surface, and a signal line (not shown) provided on the rear surface.

A dog 22 is provided on the mounting plate 20, and the dog 22 is detected by limit switches 23 and 24 fixed to the table face plate 12. That is, the signals from the limit switches 23 and 24 are output at positions where the EL display unit 21 is rotated by 180 ° counterclockwise or clockwise, respectively. Therefore, by using these signals, the rotation of the drive motor 11 can be stopped, and twisting of the signal lines and the like of the EL display unit 21 can be prevented.

FIGS. 5 to 8 are views showing examples of the measurement screen displayed on the display 2. FIG. FIG. 5 shows an inquiry screen displaying items to be interviewed for the subject. Here, rotation of the display is instructed by designating the operation menu 25 at the upper left of the screen. As a result, the subject can himself / herself input the inquiry data while viewing the inquiry screen. In addition, age, gender, occupation

FIG. 6 shows a data list screen displaying data stored in the optometry apparatus. From the data list screen, data to be input or changed can be clicked by using a mouse cursor.

FIG. 7 shows an explanatory screen based on the refractive error classification table. The measurer can rotate the display 2 to explain the contents of the optometry to the subject, and use the information to promote the subject's understanding of the subjective optometry before the optometry operation.

FIG. 8 shows a screen for explaining the measurement results. While displaying this screen to the subject, an accurate instruction can be given to the subject based on the optometry result. In the above description, in addition to the measuring head 4 on the optometry table 1,
The objective refraction measuring device 7 is arranged so that the objective, subjective, and measurement can be continuously performed. However, the present invention is also applicable to a device including only a subjective optometer. Work can be performed efficiently. In addition, the rotation mechanism of the display 2 is configured by a pulley and a wire in FIGS. 3 and 4, but may be configured by using a gear mechanism. In addition, although the wireless mouse 9 is used as the pointing means, various commands can be input from the display by using a normal wired mouse, a light pen, a touch panel, or the like.
