The present invention relates to a mobile communication terminal for displaying an image captured by a camera lens on an auxiliary liquid crystal screen, and more particularly, a mobile communication terminal for displaying an image captured by a camera lens on an auxiliary liquid crystal screen to accurately capture a user or the like. It is about.

Recently, the mobile communication terminal has been increasingly miniaturized due to high sensitivity and light weight of electronic components, and the functions of the mobile communication terminal have been diversified according to the needs of consumers. In addition to the call function of the mobile communication terminal, a mobile communication terminal having various functions such as a game, internet search, E-mail reception and transmission, payment, etc. has been generalized. Recently, a camera lens is installed in the mobile communication terminal. The mobile communication terminal has been commercialized by adding a role of a camera phone for taking the shape of an object with a mobile communication terminal and an image mobile communication terminal for taking a shape of the object with a camera and transmitting it to the counterpart.

A conventional mobile communication terminal equipped with such a camera lens will be described with reference to FIGS. 1A and 1B.

1A is a perspective view in which a camera lens is mounted in a conventional clamshell mobile communication terminal, and FIG. 1B is a configuration diagram in which a camera lens is installed in a conventional folder.

1A and 1B, the configuration and operation of a camera lens mounting apparatus of a clamshell mobile communication terminal will be described below.

In the folder type mobile communication terminal having a main body 20 and a folder 21, a microphone 24, which is a transmitter, is provided on an inner surface of the main body 20, and a plurality of key buttons 23 are installed, and a folder 21 is provided. On the inner surface of the) is provided a liquid crystal display 25 and a sign language speaker 26 showing the letters and numbers, forming a hinge portion 22 for coupling the one end of the folder 21 and the main body 20, In the upper center of the folder 21, the camera lens 27 is installed to change the direction so as to implement a mobile image terminal and a camera phone function.

The folder 21 forms a lever hole 29 at a position spaced apart from the lens hole 28 cut in order to install the camera lens 27 at the top center. Guide ribs 30 are formed on both sides of the lens hole 28, respectively, so that the central ribs 27a and 27b of the camera lens 27 are rotated on the guide ribs 30.

A rotation lever 31 is installed on one side central axis 27a of the camera lens 27 so that the rotation lever 31 protrudes slightly toward the surface of the lever hole 29 of the folder 21, and the camera lens 27 The stopper 32 which prevents rotation to more than 180 degrees is provided in the other side central axis 27b of the side).

The leaf spring 33 is provided between the guide rib 30 and the camera lens 27, respectively. The lens hole 28 has a quadrangular shape and installs a rectangular camera lens 27 in the lens hole 28, and the camera lens 27 is 180 degrees by the rotation lever 31 provided on the central axes 27a and 27b. It can rotate.

When the folder 21 is opened from the main body 20 in the above-described clamshell mobile communication terminal, the camera lens 27 installed in the upper center portion is directed inwards to be used as an image mobile communication terminal. When the user rotates the camera lens 27 using the rotation lever 31 in this state, the camera lens 27 is rotated 180 degrees and no longer rotated by the stopper 32 installed on the central axis 27b. The camera lens 27 is switched to face the outside so that it can be used as a camera phone.

The stopper 32 prevents the camera lens 27 from being rotated by more than 180 degrees so that the wire 34 which transfers the image data of the camera lens when twisted by the rotation lever 31 is not twisted, and the camera lens 27 ) Is not shaken when rotated by the leaf spring 33 installed between the guide rib 30 and the lens.

However, in the mobile communication terminal having the above structure, since the lens hole 28 provided with the camera penetrates a part of the folder 21, the size of the printed circuit board configured in the folder 21 is reduced. There are many difficulties in circuit configuration.

Accordingly, since the available area of the key button 23, the microphone 24, and the liquid crystal display 25 provided on the inner side of the folder 21 is narrowed, there is a disadvantage that it is difficult to miniaturize the mobile communication terminal.

In addition, when the camera is rotated only in one direction, the cable coupled to the camera may be twisted and damaged, so that the mobile communication terminal equipped with the camera is provided with a rotation limiting device for limiting the rotation angle of the camera. The mobile communication terminal has a disadvantage in that the product structure is complicated by additionally providing a separate rotation limiting device in addition to the camera coupling device.

In addition, there is a concern that the cable may be damaged if the cable is twisted repeatedly even if the rotation limiting device is additionally provided.

Accordingly, an object of the present invention is to provide a mobile communication terminal capable of accurately photographing a user and the like by displaying an image captured by a camera lens on an auxiliary liquid crystal screen.

3A is a configuration diagram showing the internal configuration of the hinge 300, and FIG. 3B is a cross-sectional view taken along the line A-A 'of FIG. 3A.

As shown in FIG. 3A, the hinge 300 is largely inserted into the main body hinge hole and rotates according to the rotation of the main body inserting part 310 and the cover inserted into the cover hinge hole. The cover is inserted into the insertion portion 320.

Referring to FIG. 3B, the main body inserting part 310 is formed at right angles to the rotational axis of the main body inserting part 310 and is formed symmetrically about the rotational axis, and the center of rotation of the main body inserting part 310 is defined. A streamlined cam 312 having a width in the passing direction is provided.

The cover insert 320 is a shaft 326 coupled to the main body insert 310 through the inner center in the longitudinal direction, a spring 325 positioned to surround the shaft 326, and the spring The cam is located between the cam 312 and the cam 312, and rotates according to the rotation of the lid insert 320, and includes a slider groove 323 formed to bury the cam 312. And a slider 322 for linear movement in the longitudinal direction of the shaft 326 according to the contact position with the 312. In addition, after the main body insertion part 310 is inserted into the main body hinge hole and the cover inserting part 320 is inserted into the cover hinge hole, the main body 100 and the cover 200 around the hinge 300. When the body rotates, the main body inserting part 310 rotates according to the rotation of the main body, and the cover inserting part 320 rotates according to the rotation of the cover 200. The hinge hole (not shown), the cover insertion part 320 and the cover hinge hole 240 have a cross section having one or more edges or an asymmetric cross section.

Looking at the operation of the hinge 300 is as follows.

As shown in FIG. 3A, in the state where the cam 312 is buried in the slider groove 323, the main body inserting portion 310 is inserted into the main body 100, and the lid inserting portion 320 is inserted into the lid 200. After being inserted, when the main body 100 and the cover 200 rotate about the hinge 300, the main body inserting part 310 rotates along the main body 100 and the cover inserting part. 320 is rotated along the cover 200. When the main body 100 and the cover 200 are opened, the main body inserting portion 310 and the cover inserting portion 320 rotate in opposite directions. Accordingly, the slider 322 is a shaft 326. At the same time as the center axis of the rotation and at the same time as the contact with the cam 312 is a linear movement in the direction in which the spring 325 is compressed by the depth of the slider groove 323. When the rotation angle of the main body insertion part 310 and the cover insertion part 320 reaches 180 degrees and the cam 312 reaches the position of the slider groove 323 again, the slider 322 is the spring. The spring 325 is linearly moved by the elastic force of 325, and the cam 312 is buried in the slider groove 323 again. As described above, after the main body insertion unit 310 and the cover insertion unit 320 are rotated 180 degrees, the cam 312 is buried in the slider groove 323 in the main body 100 and the cover 200. Is fixed at a certain opening angle.

In general, when the main body 100 and the cover 200 are opened, the opening angle between the main body 100 and the cover 200 is not maintained at 180 degrees, but is opened at about 150 degrees, which is a user-friendly angle. Being primarily fixed, the hinge 300 is rotated 30 degrees in a direction opposite to the direction in which the main body 100 and the cover 200 are opened during initial assembly of the main body 100 and the cover 200. It is because it is assembled in the laid state.

Figure 4a shows a shape in which the cover of the clamshell mobile communication terminal for the full opening of the cover to which the present invention is applied.

As shown in FIG. 4A, when the cover 200 is opened, the main body 100 and the cover 200 are generally fixed at 150 degrees by opening and closing at a convenient angle for the user. When the assembly of the main body 100 and the cover 200, the hinge 300 is assembled by turning the cover 30 by 30 degrees in the direction in which the cover 200 is in contact with the main body 100, thereby the main body 100 And when the cover 200 is opened at 150 degrees, the cam 312 is buried in the slider groove 323 by the elasticity of the spring 325 and fixed. In addition, compared with FIG. 1, it can be seen that the rotation opening 130 is escaped so as not to interfere with the hinge barrel 230 and the cover 200 so that the cover 200 can be rotated further in the direction of increasing the opening angle. have.

FIG. 4B illustrates a shape in which the main body and the cover are opened at 180 degrees in the state of FIG. 4A.

When a force is applied to the main body 100 and the cover 200 in a direction of increasing the opening angle in the state of Figure 4a as shown in Figure 4b the main body 100 and the cover 200 is opened to 180 degrees. At this time, since there is no part that interferes with the rotation of the cover 200, the hinge 300, the hinge knuckle 140, the hinge barrel 230 and the like will not be damaged. In addition, when the force applied in the state of Figure 4b is removed, the opening angle of the body 100 and the cover 200 is returned to the initial opening angle of about 150 degrees again to maintain the state of Figure 4a. This is because even if the cam 312 rotates by 30 degrees while the cam 312 is completely buried in the second slider groove 324, the applied force is removed because the cam 312 does not completely leave the slider groove 323. When the slider 322 is pushed toward the cam 312 by the elastic force of the spring 325, the cam 312 is completely buried in the slider groove 323.
