휴대용 단말기의 로타리 힌지{ROTARY HINGE OF MOBILE TERMINAL}ROTARY HINGE OF MOBILE TERMINAL

본 고안은 휴대용 단말기의 로타리 힌지에 관한 것으로, 더욱 상세하게는 휴대용 단말기의 덮개부를 회전시키도록 상기 덮개부의 중앙에 고정되는 휴대용 단말기의 로타리 힌지에 관한 것이다.The present invention relates to a rotary hinge of a portable terminal, and more particularly to a rotary hinge of a portable terminal fixed to the center of the cover portion to rotate the cover portion of the portable terminal.

일반적으로 정보통신 기술의 발달에 따라 이동 통신을 이용한 휴대폰 및 개인용 정보 단말기(이하 'PDA'라 함)은 점차 현대인의 필수품으로 자리 잡고 있다.In general, with the development of information and communication technology, mobile phones and personal digital assistants (hereinafter referred to as 'PDAs') using mobile communication are gradually becoming a necessity of modern people.

이와 같이 현대인의 필수품화 되어가는 휴대폰은 전화통화의 고유기능에만 국한되지 않고, 무선호출과 무선을 이용한 팩스, 정보의 송수신 및 화상을 이용한 쌍방 전화통화 등을 할수 있는 기능을 가진 최신 휴대폰이 등장하고 있으며, PDA도개인용 프로그램을 사용하여 달력, 노트, 계산기 뿐만 아니라 통신 및 이를 이용한 휴대폰 기능을 갖는 제품도 등장하고 있다.As such, mobile phones, which are becoming a necessity of modern man, are not limited to the unique functions of telephone calls, and the latest mobile phones with functions for making wireless calls, faxes using wireless, sending and receiving information, and two-way telephone calls using images are emerging. In addition, personal digital assistants (PDAs) are emerging, as well as calendars, notes, and calculators, as well as products with communications and mobile phone functions.

상기와 같이 휴대폰 및 PDA(이하 "휴대용 단말기"라 함)는 그 형태와 구조가 다양하게 개발되어 사용되고 있고, 그 중에서도 휴대폰은 조작부가 형성된 본체와 상기 본체의 전면에 결합되는 덮개를 구비하며, 상기 본체와 덮개는 그 사이에 설치되는 힌지에 의해 상호 개폐가능하도록 설치된다.As described above, mobile phones and PDAs (hereinafter referred to as "portable terminals") have been developed and used in various forms and structures, and among them, the mobile phones include a main body having an operation unit and a cover coupled to the front of the main body. The main body and the cover are installed to be openable to each other by a hinge provided therebetween.

상기와 같이 덮개를 구비한 휴대폰은 덮개의 내측에 형성된 액정화면이 세로방향이 긴 형태로 사용되고 있어 전화통화시에는 문제가 없다.As described above, the mobile phone having a cover is used in a form in which the LCD screen formed inside the cover is long in the vertical direction, and thus there is no problem during a telephone call.

그러나, 휴대용 단말기로, TV수신 또는 영화 등을 볼 때에는 액정화면과 수신데이터와의 불일치가 발생되는 분제점이 있다.However, in the portable terminal, there is a problem in that inconsistency between the LCD screen and the received data occurs when watching TV or watching movies.

즉, 일반적인 TV나 영화 화면등은 가로가 세로 보다 폭이 넓게 이루어져 있는 것이다.That is, a general TV or movie screen is made wider than it is vertical.

본 고안은 이러한 종래의 문제점을 해결하기 위하여 이루어진 것으로, 그 목적은 휴대용 단말기의 덮개부을 회전시켜 액정화면의 가로방향을 넓게 하도록 하는 휴대용 단말기의 로타리 힌지를 제공함에 있다.The present invention has been made to solve the conventional problems, and an object thereof is to provide a rotary hinge of a portable terminal to rotate the cover portion of the portable terminal to widen the horizontal direction of the LCD screen.
