Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial application field) The present invention relates to a trial lens set device used for trial production of spectacles of a subject.

2. Description of the Related Art Conventionally, in a subjective inspection apparatus for inspecting an eye of a subject in a subjective manner, a trial lens set device used for a hanging frame test of eyeglass prototyping is incorporated in an inspection table or the like. Or in the vicinity of a table.

In such a conventional device, after the trial lens is mounted on the hanging frame and the hanging frame test is performed at the final stage of the subjective examination, the subject who has completed the hanging frame test is guided to the next corner, It is common to welcome a new subject.

However, if the required number of trial lenses subjected to the above-mentioned hanging frame test for the previous subject remain on the table, it will hinder smooth perception test for the next subject.

Such a problem is particularly serious in terms of mass promotion of mass sales of eyeglasses in terms of sales promotion.

In addition, it is troublesome for the examiner in charge of the subjective examination to clear the trial lens remaining on the table at a predetermined position.

(Problems to be Solved by the Invention) The present invention has been made in view of the above circumstances, and can automatically store a trial lens in an initial storage position.
