듀얼 폴더 타입 휴대폰{dual folder-type hand-phone}Dual folder-type hand phone

본 발명은 듀얼(dual) 폴더 타입(folder-type) 휴대폰에 관한 것으로서: LCD창을 포함하는 폴더의 내부를 회전 할 수 있도록 구성하여, 하나의 LCD창으로서 폴더가 닫혔을 때 와 열렸을 때 이중으로 사용 할 수 있도록 마련된 듀얼(dual) 폴더 타입(folder-type) 휴대폰에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dual folder-type mobile phone: configured to rotate the inside of a folder including an LCD window, and when the folder is closed and opened as a single LCD window, A dual folder-type mobile phone provided for use.

휴대폰에 관한 기술은 비약적인 발전을 이루어 손안에 쏙 들어 올 수 있을 정도로 소형화 및 경량화 되었고, 화상통신까지 가능하게 되었을 뿐 만 아니라, 근거리에서 선이 없이도 데이터와 음성을 전송 할 수 있는 근거리 무선통신 기술인 블루투스(Bluetooth)의 적용으로 근거리에서 휴대폰을 원격에서 조작할 수 있게 되었다.The technology related to mobile phones has made remarkable progress, making it compact and light enough to fit in the hand, enabling not only video communication, but also Bluetooth, a short-range wireless communication technology that can transmit data and voice without a line at a short distance. Bluetooth allows users to remotely operate their mobile phones at close range.

이러한 발전은 휴대폰 이용자에게 보다 편리한 휴대 및 이용 기능을 제공함으로서 각광을 받고 있다. 휴대폰의 소형화 및 경량화에 있어서는 휴대폰에 사용되는 전자 부품의 소형화 및 경량화에 못지않게 중요한 것이 휴대폰의 기본적 구조 형태이다. 현재까지 개발 및 판매되고 있는 휴대폰들 중에, 보편화된 휴대폰 형태의 하나가 폴더 타입(folder-type) 휴대폰이다.These developments are in the limelight by providing more convenient portable and use functions for mobile phone users. In the miniaturization and light weight of a cellular phone, the basic structural form of the cellular phone is as important as the miniaturization and lightweight of electronic components used in the cellular phone. Among the mobile phones that have been developed and sold to date, one of the most popular types of mobile phones is a folder-type mobile phone.

폴더 타입(folder-type) 휴대폰은 폴더(folder)가 본체에 장착된 키패드를 보호하여 키의 오동작을 방지하고, 통화모드시 통화중의 음의 반사판 역활을 수행하여 음을 모아주며, 폴더에 스피커장치나 LCD창을 설치할 수 있기 때문에 본체 소형화에 대단히 유리하다.Folder-type mobile phone protects the keypad mounted on the main body of the folder to prevent the malfunction of the key, and collects the sound by performing the role of the reflector of the sound during the call mode, and the speaker in the folder It is very advantageous to miniaturize the main body because it can install a device or LCD window.

도1은 종래의 일 실시예에 따른 듀얼(dual) 폴더 타입(folder-type) 휴대폰의 사시도로서, 폴더부(10)가 닫혔을 때의 형태(33a)와 열렸을 때의 상태(3b)를 나타내는 사시도 이다. 통상적인 폴더 타입 휴대폰은 크게 세부분으로 구성되며, 본체부(20)와 폴더부(10), 본체부(20)와 폴더부(10)를 연결시키는 힌지부(30)로 구성된다. 상기 폴더부(10)는 힌지축(33b)를 중심으로 개폐 된다. 이때 상기 폴더부(20)에는 스피커장치(40), 내부LCD창(3d)와 외부LCD창(3c), 화상통화를 위한 렌즈(60)가 장착되고, 본체부(20)에는 다수개의 키를 포함하는 키패드가 설치되어 데이터를 입력한다. 그리고, 본체부(20)의 최하단에 마이크장치(50)가 위치한다.1 is a perspective view of a dual folder-type mobile phone according to a conventional embodiment, showing a form 33a when the folder portion 10 is closed and a state 3b when opened. It is a perspective view. A typical folder type mobile phone is composed of large parts, and includes a main body portion 20 and a folder portion 10, and a hinge portion 30 connecting the main body portion 20 and the folder portion 10. The folder portion 10 is opened and closed around the hinge shaft 33b. At this time, the folder unit 20 is equipped with a speaker device 40, the internal LCD window (3d) and the external LCD window (3c), the lens 60 for the video call, the main body 20, a plurality of keys An included keypad is installed to enter data. And the microphone apparatus 50 is located in the lowest end of the main-body part 20. As shown in FIG.

이러한 종래의 듀얼(dual) 폴더 타입(folder-type) 휴대폰은, 폴더부(10)에 외부LCD창(3c)과 내부LCD창(3d)을 두어, 폴더부(10)가 닫힌 상태에서는 외부LCD창(3c)을 이용하고, 폴더부(10)가 열린 상태에서는 내부LCD창(3d)을 이용 할 수 있도록 하여, 사용자의 편리성을 도모하고자 하였으나, 다음과 같은 문제점이 있다.The conventional dual folder-type mobile phone has an external LCD window 3c and an internal LCD window 3d in the folder unit 10, and the external LCD in the state in which the folder unit 10 is closed. While using the window 3c and allowing the internal LCD window 3d to be used in the open state of the folder unit 10, attempts to facilitate user convenience have the following problems.

폴더부(10)에 내부LCD창(3d)과 외부LCD창(3c), 두개의 LCD창이 설치되어, 폴더부(10)의 두께가 두꺼워지고 무거워져서 소형화 및 경량화에 불리해졌으며, 이에 따른 추가 비용이 발생하여 제조원가가 높아 졌다. 또한, 현재에는 외부LCD창(3c)을 내부LCD창(3d)보다 작은 LCD창으로 구성하여 수신 상태 및 배터리 상태 등의 간이 정보를 제공하고 있으나, 근거리에서 선이 없이도 데이터와 음성을 전송할 수 있는 근거리 무선통신 기술인 블루투스(Bluetooth)의 적용으로, 근거리에서 휴대폰을 원격에서 조작할 수 있게 됨에 따라 폴더부(10)가 닫힌 상태에서의 통화가 증대하고 있다, 이러한 경우 현재의 작은 외부LCD창(3c)으로서는 효율적으로 대응할 수 없으며, 외부LCD창(3c)을 내부LCD창(3d)의 크기로 확대한다 하더라도, 소형화 및 경량화에 더욱더 불리해 지며 제조원가의 추가 이용 또한 증대되는 문제점이 있다.Two LCD windows, an internal LCD window 3d and an external LCD window 3c, are installed in the folder part 10, so that the thickness of the folder part 10 becomes thick and heavy, which is disadvantageous in miniaturization and light weight, and thus additional. Costs have increased and manufacturing costs have increased. In addition, at present, the external LCD window 3c is configured as an LCD window smaller than the internal LCD window 3d to provide simple information such as a reception state and a battery state, but can transmit data and voice without a line at a short distance. With the application of Bluetooth, which is a short-range wireless communication technology, as the mobile phone can be remotely operated at a short distance, calls are increasing while the folder unit 10 is closed. In this case, the current small external LCD window 3c ) Cannot be effectively coped with, and even if the external LCD window 3c is enlarged to the size of the internal LCD window 3d, it is more disadvantageous for miniaturization and weight reduction, and there is a problem that further use of manufacturing cost is also increased.

본 발명은 상술한 문제점을 해결하기 위한 것으로서: LCD창을 포함하는 폴더의 내부를 회전 할 수 있도록 구성하여, 하나의 LCD창으로서 폴더가 닫혔을 때와 열렸을 때 이중으로 사용 할 수 있도록 마련된 듀얼(dual) 폴더 타입(folder-type) 휴대폰을 제공하기 위한 것이다.SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems: by configuring the inside of the folder including the LCD window can be rotated, a dual LCD provided as a single LCD window to be used when the folder is closed and double ( dual) To provide a folder-type mobile phone.
