Description

Camera installation structure of mobile terminal {ESTABLISHMENT STRUCTURE FOR CAMERA IN MOBILE DEVICE}

The present invention relates to a foldable portable terminal, and more particularly, to a foldable portable terminal in which a user can easily photograph a subject in all directions while checking an image of the subject through an LCD window.

A portable terminal is a personal information terminal that a user carries and uses, such as a mobile phone and a PDA. Recently, as the demand of consumers for multimedia increases, a large number of portable terminals having functions of playing video, photographing, and playing high-quality sound have been developed and sold. In particular, in order to shoot a video, it is necessary to attach the camera. However, there is a disadvantage that it is difficult to properly use the camera's original functions by attaching the camera to the limited space of the portable terminal.

1 to 3 are diagrams illustrating a conventional portable terminal with a camera for each type.

1 is a perspective view of a folder fixed type portable terminal, in which a main part 10 provided with a keypad 11 and a folder part 20 provided with a screen (not shown) are hinged by a hinge part 30, and a camera ( 22 is installed on the upper surface of the folder part 20.

Therefore, when the user wants to photograph the subject, the folder unit 20 is opened, the upper surface of the folder unit 20 faces the subject, and after confirming the image to be photographed on the screen (not shown), the keypad 11 Use to shoot.

However, the conventional portable terminal having such a configuration has a disadvantage in that the user cannot check an image to be photographed on a screen (not shown) when photographing a subject located on the user side based on the portable terminal.

2 is a front view of a portable terminal in which a camera is mounted on a hinge portion, in which a main portion (not shown) having a keypad (not shown) and a folder portion 120 having a screen (not shown) are installed on the hinge portion 130. The hinge is coupled by, the camera 122 is installed on the hinge 130.

Since a conventional portable terminal having such a configuration can take a picture by rotating the hinge unit 130, the portable terminal can take a picture while checking an image to be captured on a screen (not shown) even when the subject is located at either the front or the rear of the user.

However, when the subject is located on the side of the user, it is difficult for the user to check the image through a screen (not shown).

3 is a perspective view of a swivel type portable terminal, in which a main part 210 having a keypad 211 and a folder 220 having a screen 221 are hinged by a hinge 230. The hinge portion 230 includes a first hinge portion 231 hinged so that the folder portion 220 can be folded with the main portion 210, and the folder portion 220 is perpendicular to the first hinge portion 231. It consists of a second hinge portion 232 coupled to the first hinge portion 231 so as to rotate freely about the axis of rotation in the direction.

The camera 222 is installed on the side of the first hinge portion 231.

In the conventional swivel type portable terminal as described above, the second hinge part 231 may not only rotate in a direction in which the folder part 220 is folded with the main part 210 by the first hinge part 231. As a result, the folder portion 220 can also rotate in the direction perpendicular to the hinge axis of the first hinge portion 231, so that the folder portion 220 can face almost all directions.

Accordingly, the user may photograph the subject located in any direction while looking at the screen 221.

However, the second hinge portion is composed of one rotating shaft in structure, and all the loads generated when the folding of the folder portion 220 is concentrated on the second hinge portion 232 has a problem in that the structural weakness.

The present invention has been made to solve the above problems, and the user can easily photograph the subject in all directions while checking the image of the subject through the LCD window, and provides a structurally robust folding portable terminal. The purpose.
