The present invention provides a portable terminal comprising: a main body having a handle and being portable； An eyepiece housing installed to be movable forward and backward on one side of the passage portion； An eyepiece provided inside the eyepiece housing for observing the eyes of the examinee at an eye side of the observer； An objective lens which is provided on the other side of the passage portion and which is located on the eye side of the examinee so as to form an image on the eye side of the examinee； A relay lens positioned between the eyepiece lens and the objective lens and reversing the image reversed by the objective lens； An illumination unit for irradiating light for observing a fundus of a subject； And an eyepiece lens unit which is installed to be rotatable in both directions so as to expose or protrude from the main body, and which moves the eyepiece lens housing repeatedly forward and backward by unidirectional rotation of the operating wheel. According to the present invention, it is possible to move the eyepiece back and forth only by unidirectional rotation of the operating wheel, thereby improving convenience of operation and reliability of operation and improving assembling property of the fixing member for fixing the operating wheel and lever And it is possible to eliminate the inconvenience of the observer by making it possible for the observer to wear the glasses when inspecting the eyes of the examinee and to secure the distance between the observer's eye and the eyepiece lens to protect the eyepiece from the external contact And the reflected light by the cornea of the examinee can be suppressed.본 발명은 손잡이가 마련되고, 휴대가 가능하며, 전후로 통로부가 형성되는 본체； 상기 통로부의 일측에 전후로 이동 가능하게 설치되는 접안렌즈하우징； 상기 접안렌즈하우징의 내측에 설치되고, 관찰자의 눈 측에 위치하여 피검자의 눈을 관찰하기 위한 접안렌즈； 상기 통로부의 타측에 설치되고, 피검자의 눈 측에 위치하여 피검자의 눈 측에 상을 맺도록 하는 대물렌즈； 상기 접안렌즈와 상기 대물렌즈 사이에 위치하고, 상기 대물렌즈에 의해 반전된 상을 역전시키는 릴레이렌즈； 피검자의 안저를 관찰하기 위한 광을 조사하는 조명부； 및 상기 본체에 노출 내지 돌출되도록 작동휠이 양방향으로 회전 가능하게 설치되고, 상기 작동휠의 일
