The present invention relates to an ophthalmologic apparatus, and more particularly, to an ophthalmologic apparatus which comprises a lens disc and a cover unit which are moved or rotated by moving a pair of lens discs in the body during a single- To an optometric apparatus capable of preventing damage or psychological anxiety of the subject in advance.
The optometric apparatus is a mechanism for measuring the visual acuity of the examinee or examining the state of the eye, and a method of selecting a lens suitable for the visual acuity of the examinee while arranging a plurality of lenses sequentially in front of the eye of the examinee is used.
In the initial stage, after a wearer wears a frame made in the form of an eyeglass, a worker inserts a plurality of trial lenses at positions corresponding to the eyes of the subject in the frame, or inserts a plurality of trial lenses to inspect the visual acuity of the subject, The device was used.
However, such passive optometric apparatuses require the operator to arbitrarily select the trial lenses. In addition to this, it takes a considerable amount of time to select appropriate lenses, and a difference in the selection of the trial lenses is caused according to the skill of the operator. A problem that the proper lens can not be selected has arisen.
In order to solve such a problem, an automatic optometric apparatus has been developed and used which automatically rotates a circular disk provided with a plurality of trial lenses to select a trial lens suitable for the visual acuity of the subject.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and it is an object of the present invention to provide a lens disk and a cover which are moved or pivoted by allowing a pair of lens discs to move or pivot inside a main body, The present invention provides an optometric apparatus capable of preventing physical damage of a subject due to a subject and psychological anxiety of the subject in advance.
Another object of the present invention is to provide a method of measuring an unilateral PD by measuring the distance of one coin from the nose of a subject based on the subject's nose at the time of unilateral PD measurement by forming a co- And the like.
Another object of the present invention is to provide an ophthalmologic apparatus which can easily and accurately perform monocular PD measurement operation or ophthalmologic examination work by forming a face support portion on the back surface of a main body to support a face portion of the subject.
According to an aspect of the present invention, there is provided a portable terminal, comprising: a main body fixedly installed in a region to be installed; a pair of lenses, which are moved in left and right directions on one side of the main body, A lens provided on one side of the main body, a moving force providing means provided on one side of the main body and connected to one side of the lens disk to provide power to the lens disk, And a rotatable force providing means coupled to the other side for providing a rotational force to rotate the lens disc in the left-right direction, wherein the main body has a single receiving space formed therein so that the lens disc and the moving- And the ophthalmologic apparatus is accommodated in the space at the same time.
The main body is preferably formed on one side corresponding to the nose of the subject and includes a coagulation part for supporting the nose of the subject.
Further, the main body has a nose insertion groove formed at one side of the rear surface corresponding to the nose of the examinee, and the co-jigged portion is disposed at a position corresponding to the nose insertion groove at a predetermined interval from the back surface of the main body A supporting unit for supporting the nose of the examinee on one side thereof and an elastic member which is disposed between the supporting unit and the rear surface of the main body and which provides the elasticity of the supporting unit to the rear of the main body.
Preferably, the main body is formed in a shape corresponding to the face of the examinee on one side of the back side, and a face supporting part supporting one side of the face of the examinee is formed.
According to the present invention as described above, a pair of lens discs for moving left or right or turning left and right, and power means for providing a moving force and a turning force, respectively, are accommodated in a single cover portion, The operation of the constitution is performed inside the cover portion, so that there is an effect that the physical damage of the subject and the psychological anxiety of the subject due to the lens disk and the cover portion which are horizontally or horizontally rotated can be prevented in advance.
In addition, the present invention can measure an accurate monocular PD by measuring the distance of one coin from the subject's nose with respect to the subject's nose at the time of monocular PD measurement by forming the coagulated portion where the nose of the subject is supported on one side of the body There is an effect.
In addition, by forming the face support portion supporting the face portion of the examinee on the rear face of the body, there is an effect that the eye examination operation or the monocular PD measurement operation can be performed more easily and accurately.
