Next, a circuit system of the trial lens setting device 1 will be described with reference to FIG.

The trial lens set device 1 is configured to control the display elements 14 based on various optometry information from the optometry devices 22 and 23.
a, 14b, 14c,…, 15a, 15b, 15c,…, 16a, 16b, 16c,…, 17a, 17
, 17c,... are provided.

The display control means 35 is an interface 36 for transmitting information between the optometry devices 22 and 23, and fetches optometry information from the optometry devices 22 and 23 via the interface 36, and displays a display corresponding to the content. CPU 37 that sends control signals
And a storage unit 38 for storing the optometry information, and a display controller 39 for transmitting a lighting signal for lighting each display element based on a display control signal from the CPU 37.

The display elements 14a, 14b, 14c, ..., 15a, 15b, 15c, ..., 16a,
, 17a, 17b, 17c, ... are connected to the display controller 39 via the corresponding microswitches MSW.

Further, the display controller 39, the battery 40 via the micro switch MSW ₀ provided on the lower surface of the eye examination table 21 is connected, when the micro switch MSW ₀ becomes open, the power supply of the display controller 39 is interrupted Thus, one of the display elements being turned on is turned off.

Next, the operation of the trial lens set device 1 having the above configuration will be described.

For example, the SPH value 9.0, CYL value of the right eye from the subjective optometer 23
It is assumed that the optometry information including the 2.75 SPH value of the left eye and the CYL value of 3.0 is sent to the CPU 37 via the interface.

The CPS 37 sends the optometry information to the storage unit 38, and sends a display control signal including these contents to the display controller 39. Thereby, the display controller 39
A lighting signal is sent to the display element 15a corresponding to the SPH value 9.0 of the right eye and the display element 17b corresponding to the CYL value 2.75, and both display elements 1
Turn on 5a and 17b.

At the same time, the display controller 39 sends a lighting signal to the display element 14b corresponding to the SPH value 8.0 of the left eye and the display element 16a corresponding to the CYL value 3.0, and turns on both display elements 14b and 16a. At this time, if there is no corresponding trial lens, a plurality of the lenses are displayed in combination so as to have a predetermined value.

This allows the examiner to illuminate the display elements 15a, 17b, 14b, 16
The trial lenses 10a, 12b, 9b, 11a respectively corresponding to a can be identified immediately and without error, and these can be taken out and mounted on the mounting portions 33a, 33b of the trial frame 30.

Each trial lens 10a, 12b, 9b, 11a is stored in the storage section 6a, 8 respectively.
When detached from b, 5b, 7a, all of the corresponding microswitches MSW are in the open state, so that all the lit display elements 15a, 17b, 14b, 16a are turned off. This eliminates unnecessary power waste. In addition, if the color is turned on instead of being turned off even if it is removed, it is easy to understand when returning to the original state, and it is easy to understand when taking out a trial lens having a value before and after the value obtained by the optometry.

Each of the trial lenses 10a, 12b, 9b, 11a taken out of the trial lens set device 1 is stored in the original storage unit.
6a, after returning 8b, 5b, the 7a, when fully pushed trial lens set apparatus 1 in optometry table 21, micro-switch MSW ₀ shown in FIG. 4 is opened, thereby, the power source of the display controller 39 is the cross-sectional Since each of the display elements corresponds to a corresponding one, no power is wasted when the trial lens set device 1 is not used.

It is more effective if applied to a trial lens set device having a larger number of trial lenses using a trial lens in which a trial lens for refractive power and a trial lens for cylindrical power are integrally formed. Therefore, a display means such as a lamp may be provided to identify the corresponding drawer.

The present invention can be variously modified in addition to the embodiments described above.

For example, by classifying the display elements such as red for the right eye and green for the left eye, the identification efficiency of the examiner can be further improved.

In addition, a display unit indicating the angle of the cylindrical axis of each trial lens may be provided at an appropriate place of the storage unit.

[Effects of the Invention] According to the present invention described in detail above, with the above-described configuration, the trial lens corresponding to the optometry information of the subject can be accurately and promptly operated under the operations of the lighting control unit and the display unit. And a trial lens set device that can be used for a trial frame.
