Hereinafter, an embodiment of the structure of a mobile communication terminal equipped with a camera according to the present invention will be described in detail with reference to the accompanying drawings.

Figure 3 is a perspective view showing the appearance of a mobile communication terminal equipped with a camera according to the present invention, Figure 4 is an exploded perspective view of a mobile communication terminal equipped with a camera according to the present invention, Figures 5a and 5b are constituting the present invention 6A and 6B are cross-sectional views illustrating 6-6 'of FIG. 3 in a state in which a folder part and a main body part are slid and closed or open by sliding the spring module of the slide module. 7A to 7D are side views for explaining the operation of the present invention.

Referring to FIGS. 3 and 4, the structure of the mobile communication terminal equipped with the camera of the present invention includes a folder unit 100 having a first hinge arm 120 embedded so that the camera 130 can photograph one direction. )Wow; A connection part 200 provided with a second hinge arm 210 which forms a hinge coupling with the first hinge arm 120 so that the folder part 100 is rotated and opened or folded; The connection part 200 includes a main body 400 that is opened or closed by sliding while being fastened to be able to slide a predetermined distance.

The folder unit 100 includes a display 110 on one surface and displays multimedia information such as information on the operation of the mobile communication terminal and pictures and videos, and at one end thereof, a first hinge arm 120 is installed. The external display 140 is provided on the surface.

In the first hinge arm 120, a digital camera 130, such as a charge-coupled device (CCD) or a complementary metal oxide semiconductor (CMOS) type, is embedded to photograph the outside in the direction in which the display 120 is displayed.

The connecting portion 200 has a second hinge arm 210 which forms a hinge coupling with the first hinge arm 120 and can rotate at a predetermined angle with the folder portion 100. In this embodiment, the first hinge arm ( 120 is the center hinge arm, the second hinge arm 210 is composed of a side hinge arm to form a hinge coupling, the folder portion 100 is folded to the connecting portion 200 in the first hinge arm 120 The built-in camera 130 faces rearward.

The bottom surface of the connecting portion 200 is slidable by being fastened to the main body 400 by the slide module 300, the slide module 300 is the sub-rail 310 and the main body 400 is fixed to the connecting portion 200 Consists of the main rail 320 is fixed to the guide ribs 311 formed to form a '' 'in the sub-rail 310 in the guide groove 321 provided on the side of the main rail 320 is inserted into the guide As the rib 311 slides in the guide groove 321, the subrail 310 and the main rail 320 are slidable with each other.

The direction in which the subrail 310 slides with respect to the main rail 320 is in a state in which the connection part 200 fixed to the subrail 310 and the main body part 400 fixed to the main rail 320 overlap and are closed. The connection portion 200 is a direction protruding upward of the main body portion 400, the sliding distance is suitably such that the hinge of the connection portion 200 is completely exposed to the rear of the main body portion 400.

When the subrail 310 and the main rail 320 are fixed to the connecting portion 200 and the main body 400, respectively, the subrail 310 is inserted from the bottom of the connecting portion 200 to be screw holes 312 of the side surface. It is fixed by screwing through, the main rail 320 is seated in the groove (410) groove (410) formed to fit the shape of the main rail 320 in the main body 400 screw hole 322 of the side It is fixed by screwing through.

Meanwhile, a spring device 330 may be added to the slide module 300 so that the subrail 310 slides only a predetermined distance by the external force with respect to the main rail 320.

Referring to FIG. 5, the spring device 330 has one end protruded from the subrail 310 while the spring 332 is installed on the lever shaft 331 rotatably fixed to the main rail 320. When the subrail 310 is inserted into the insertion groove 333 and the subrail 310 slides the main rail 320 by a predetermined distance by an external force while the subrail 310 is closed with the main rail 320 (Fig. 5a), the lever shaft 331 is a lever movement, the spring 332 is compressed by the insertion groove 333 and is restored while applying the elastic force to the sub-rail 310, the rest is automatically slide the sub-rail 310 is The main rail 320 is opened (FIG. 5B).

In addition, the slide module 300, the detection means for applying a detection signal to the control circuit for controlling the overall function of the mobile communication terminal by detecting the open or closed state by sliding the subrail 310 with respect to the main rail 320 340 is added.

Since the detection means 340 has a number of well-known technologies, for example, the permanent magnet 341 and the magnetic force sensor 342 are respectively provided at corresponding positions of the subrail 310 and the main rail 320. In the state in which the subrail 310 and the main rail 320 are closed, the magnetic force sensor 342 may apply a detection signal to the control circuit, and in the open state, may detect the slide state without generating a detection signal. .

When the control circuit recognizes that the folder unit 100 is opened by the sensing means, the control circuit drives the camera photographing menu, so that the user can take a picture if there is any key input.

The folder unit 100 and the main body unit 400 are connected to each other by a signal connection line such as a flexible printed circuit board (FPCB) 500, and power signals and operation signals are exchanged.

The FPCB 500 is inserted into the second hinge arm 210 through the first hinge arm 120 from the folder part 100 and then slides integrally with the subrail 310 as shown in FIG. 6. After being guided through the guide 600 is connected to the main body 400 to connect a signal.

The FPCB guide 600 protrudes in a plate shape from the side of the subrail 310, or is fixed integrally to the connecting portion 200 and slides together with the subrail 310 while the subrail 310 slides on the main rail 320. In the closed state (FIG. 6A) or the open state (FIG. 6B), the excess length of the FPCB 500 is guided so as not to be twisted in the connection part 200, thereby preventing damage to the FPCB 500.

Looking at the use and operation of the mobile communication terminal equipped with a camera according to the present invention made as described above with reference to FIG.

The user normally carries and stores the folder unit 100 of the mobile communication terminal by sliding and closing the main body unit 400 while being rotated and folded. (FIG. 7A).

If the user wants to make a phone call or the like, the user may simply rotate and open the folder unit 100. At this time, since the camera 130 built in the first hinge arm 120 faces the user, the camera photographing menu using an input key may be used. The user may take a picture of himself / herself while viewing the display 110 (FIG. 7B).

Alternatively, when the folder unit 100 is rotated and opened, when the folder unit 100 is opened by sliding the folder unit 100 with respect to the main body unit 400, the detecting unit 340 detects the slide open state and applies a signal to the control circuit to automatically open the folder unit 100. By entering the camera shooting menu, you can shoot yourself (Fig. 7c).

If the user wants to photograph the subject at the rear of the terminal, when the folder unit 100 is in a folded state when it is rotated, the sensor unit 340 simply slides and opens the folder unit 100 with respect to the main body unit 400. And automatically enters the camera shooting menu. At this time, the camera 130 embedded in the first hinge arm 120 protrudes with respect to the main body 400 in the rearward facing direction and thus is exposed to the external display 140. It is possible to take a picture by a predetermined key operation. (FIG. 7D)

If the folder unit 100 is rotated and opened in this state, the camera 130 faces the user again, thereby photographing the user himself (FIG. 7C).

Meanwhile, the arrow shown in FIG. 7 indicates a direction in which the camera 130 can take a picture.

According to the mobile communication terminal according to the present invention as described above, both the front and rear of the mobile terminal can be conveniently photographed, and the operation for photographing is novel, thereby providing a new feeling of use.
