Description

Camera fixing device for portable terminal {FIXED APPARATUS FOR CAMERA IN MOBILE PHONE}

The present invention relates to a camera fixing apparatus of a portable terminal, and more particularly, to rotate a camera housing fixedly rotatable to a portable terminal to provide a user with a feeling of click and at the same time to reduce the wear of the contact portion contacted during rotation. It relates to a camera fixing device of a portable terminal.

With the development of the information and communication industry, portable terminals having various functions and forms are being released. Typical portable terminal types include a general bar type, a flip type, a folder type, and a slide type terminal, and various additional functions are added to the terminals in addition to a voice call with the other party.

Recently, the portable terminal has been widely introduced as a 'video communication portable terminal' having a camera in a device for transmitting and receiving images as well as audio or photographing a subject. Such a portable terminal is provided with a detachable camera so that it can be used after being coupled to the terminal whenever necessary, or built in the terminal so that the user can take a picture when desired.

As described above, a folder type portable terminal equipped with a camera is described as an example among various types of portable terminals equipped with a camera.

1 is a perspective view of a portable terminal having a conventional camera, Figure 2 is a cross-sectional view taken along the line A-A of FIG. As shown in these figures, as shown in these figures, the portable terminal has a terminal body 10 composed of a lower folder 11 and an upper folder 21 rotatably coupled to each other, and a terminal body 10 It is provided with a camera 30 that is rotatably coupled with respect to.

The lower folder 11 is provided with a printed circuit board (not shown) constituting a circuit to perform various functions, the battery 13 for power supply is coupled to the back. A pair of fixed hinge parts 15a and 15b are formed at the upper edge of the lower folder 11 so that the upper folder 21 can be coupled to be rotated relative to each other, and the camera 30 is located at one side along the rotation axis direction. Rotation guide 19 is formed to support the rotatably.

On the inner and outer surfaces of the upper folder 21, main LCD panels (not shown) and sub LCD panels 22 are provided to output predetermined visual information, respectively, and fixed hinge parts 15a and 15b are formed at one edge thereof. Movable hinge portion 23 is formed to be coupled between. Inside the movable hinge portion 23 and the fixed hinge portion 15b on one side, each part of the hinge device 25, which is composed of two parts that are coupled to be movable relative to each other, is accommodated and coupled to the inside of the fixed hinge portion on the other side. The flexible printed circuit boards (FPCBs) 26 and the LCDs drawn out from the upper folder 21 are accommodated so as to face the printed circuit board side, respectively.

Meanwhile, the camera 30 includes a camera module 31, a camera housing 33 forming a receiving space of the camera module 31, and a handle member 37 coupled to one side of the camera housing 33. Doing.

The camera housing 33 is formed to have a cylindrical shape, and one side of the camera housing 33 is coupled to the fixed hinge portion 15a at a predetermined depth, and a viewing window 34 is formed on the circumferential surface to allow light to enter therein.

A fitting ring 39 is coupled between the rotation guide 19 and the module housing 33 to prevent play along the rotation axis direction of the camera housing 33, and the handle member 37 has a rotation axis direction. Accordingly, one side passes through the rotation guide 19 and the fitting ring 39 to be in contact with one side of the module housing 33 and is fixedly rotatably integrally coupled by the screw 38.

By such a configuration, the user can take a picture or video while turning the handle member 37 appropriately so that the camera housing 33 is rotated with respect to the terminal body 10 so that the camera module 31 faces the subject.

However, since the portable terminal having the conventional structure configured as described above has a structure in which the contact part is simply in sliding contact and is temporarily stopped when the camera module 31 is rotated so that the camera module 31 faces the subject. The use of time causes wear on the contact portion, which makes it difficult to fix the camera module 31 in a desired direction.

The object of the present invention devised in view of the above point is to improve the camera fixing structure of the portable terminal to provide a click feeling during rotation and at the same time portable to easily adjust the direction to the camera module toward the desired direction It is to provide a camera fixing device of the terminal.
