As illustrated in FIG. 1, the slide type mobile communication terminal 100 is unfolded or folded while the LCD unit 110 slides in the longitudinal direction of the main body 120.

The camera 130 is installed at an upper end of the LCD unit 110, that is, at an end located in a moving direction to be unfolded. The camera 130 is mounted on the upper case 112H and the lower case 112L of the LCD unit 110. Groove 113 of a predetermined width and length is formed to be. The camera 130 is positioned inside the groove 113, and the rotation shafts 134a and 134b of the camera 130 are inserted into two inner surfaces facing each other in the groove 113 to rotate 270 degrees. In the rotation range of 270 degrees, the camera lens unit 131 is in the groove 113 at a point where the direction of the camera lens unit 131 is located in a direction opposite to the direction of the LCD 111 (hereinafter referred to as a 'base direction'). 270 degrees to the point towards the inner bottom surface of the. Therefore, the lens unit 131 of the camera 130 may be secured in the 180 degree photographing range of the front, the up, and the rear of the mobile communication terminal 100 located in one direction.

Hereinafter, the mobile communication terminal configured as described above will be described in more detail.

As shown in FIG. 2, a groove 113 is formed at an upper end of the LCD unit 110. The groove 113 has a predetermined depth, and the width of the groove 113 is greater than or equal to the length of the camera 130. to be. The LCD unit 110 is divided into an upper case 112H and a lower case 112L, and the grooves 113 are divided into upper portions of the upper case 112H and the lower case 112L, respectively.

Through-holes 116 are formed at two inner side surfaces of the groove 113 formed at the upper end of the LCD unit 110. The first and second rotation shafts 134a and 134b protruding from both side ends of the camera 130 are respectively inserted into the through holes 116, respectively, and are centered on the first and second rotation shafts 134a and 134b. The camera 130 rotates about the axis.

On the other hand, a stopper 119 is formed inside the lower case 112L corresponding to the first rotation shaft 134a, and the stopper 119 limits the rotation angle of the camera 130 to 270 degrees. In addition, the inner side of the upper case 112H is provided with a pressing member 140 to press the first rotating shaft 134a, thereby preventing the self-rotation of the camera 130, to maintain the rotation angle of the camera 130 do. Meanwhile, the FPCB 139 extending from the camera module 132 passes through the second rotation shaft 134b and surrounds the second rotation shaft 134b, and then is connected to the PCB 118 of the LCD unit 110.

In more detail, sixteen grooves 135 are formed along the circumference of the first rotation shaft 134a in the longitudinal direction of the first rotation shaft 134a. And a stopper rib 137 is formed in the cross section of the 1st rotating shaft 134a. Here, the camera 130 includes a camera module 132 having a large camera lens, a camera case 133 formed at both ends of the first and second rotation shafts 134a and 134b surrounding the camera module 132, and And an FPCB 139 extending from the camera module 132 and connected to the PCB 118. In the camera 130 configured as described above, the stopper rib 137 is eccentrically formed without being located at the center of the cross section of the first rotation shaft 134a. Therefore, the stopper rib 137 rotates while drawing the trajectory of the circle along the rotation of the first rotary shaft 134a.

Inside the upper case 112H of the LCD unit 110, a stopper 119 is formed in contact with the stopper rib 137 formed on the first rotation shaft 134a of the camera 130, and the stopper 119 is a stopper rib ( Located in the trajectory of the circle drawn by 137, the stopper rib 137 is in contact with the side and top of the stopper 119. That is, when the camera 130 is located in the basic direction, the stopper rib 137 is located in contact with the side of the stopper 119, and when the camera 130 rotates, the stopper rib 137 rotates along the trajectory of the circle. As described above, when the camera 130 rotates 270 degrees and the camera lens unit 131 is positioned toward the inner bottom surface of the groove 113, the stopper rib 137 contacts the top surface of the stopper 119. Therefore, the camera 130 rotates only by 270 degrees due to the interference between the stopper rib 137 and the stopper 119.

Meanwhile, the pressing member 140 is fixed inside the upper case 112H of the LCD unit 110. The pressing member 140 is a latch plate 141 having a 'c' shape in which the middle portion in the longitudinal direction is bent twice inward, and includes a first rotating shaft (B) between two opposite inner surfaces 141I of the latch plate 141. 134a is positioned to receive elastic force from two inner surfaces 141I. In addition, protrusions 143 are formed on the two inner surfaces 141I, respectively, and the protrusions 143 match the grooves 135 formed on the first rotation shaft 134a. Thus, as the camera 130 rotates, the protrusion 143 of the latch plate 141 is beyond the groove 135 to mate with the other groove 135. At this time, the force applied by the user to rotate the camera 130 must apply a force greater than or equal to the elastic force of the latch plate 141, so that the camera 130 rotates to prevent self-rotation of the camera 130. In the latch plate 141, the screw 145 penetrating through the closing surface 141C is fastened to the inner surface of the upper case 112H of the LCD unit 110. The latch plate 141 is made of stainless steel, has a thickness of 0.2 mm, and the protrusion 143 protrudes 0.3 mm in the shape of a dome. And the depth of the groove 135 is preferably 0.3mm.

On the other hand, the FPCB 139 which penetrates the second rotating shaft 134b is connected to the PCB 118 after the second rotating shaft 134b is loosely wound around the second rotating shaft 134b. In this way, while the FPCB 139 is wound around the second rotation shaft 134b, the FPCB 139 is tightly wound or loosened loosely on the second rotation shaft 134b in accordance with the rotation of the camera 130. 139 may leave the second rotation shaft 134b. In order to prevent this, the partition 117 facing the end of the second rotation shaft 134b is formed in the lower case 112L of the LCD unit 110. The partition wall 117 prevents the FPCB 139 surrounding the second rotation shaft 134b from scattering outward of the second rotation shaft 134b. Here, in the basic direction of the camera lens unit 131, the FPCB 139 is in a state of winding the second rotation shaft 134b to the maximum. In addition, in the basic direction of the camera lens unit 131, the stopper rib 137 is positioned in contact with the side surface of the stopper 119.

When the camera 130 is rotated 270 degrees in the basic direction so that the camera lens unit 131 faces the inner bottom surface of the groove 113, the FPCB 139 is maximally loosened, and the stopper rib 137 ) Is in contact with the top of the stopper 119.

Meanwhile, as shown in FIG. 4, the magnetic force sensor 150 is positioned at the upper end of the PCB 118 embedded in the LCD unit 110, and the magnet 151 is fixed inside the camera case 133. Therefore, as the camera 130 rotates, the magnet 151 moves away from or close to the magnetic force sensor 150. The magnetic force sensor 150 compares the actual magnetic force measured in real time with a set magnetic strength to measure actual magnetic force. Generates an electrical signal when is greater than or less than the set magnetic strength. As shown in FIG. 4, the magnet 151 is closest to the magnetic force sensor 150 when rotated 180 degrees in the basic direction of the camera lens unit 131. As such, when the magnet 151 is closest to the magnetic force sensor 150, the magnetic force sensor 150 generates an electrical signal, and the upper and lower sides of the LCD 111 screen are changed by the signal.

In the mobile communication terminal 100 configured as described above, the outside of the camera case 133 is formed with a plurality of slip preventing grooves 136 in the longitudinal direction. The slip preventing groove 136 is configured to prevent slipping when the user rotates the camera 130. In the rotation of the camera 130 by 270 degrees, the protrusion 143 of the latch plate 141 makes eight clicks while crossing the eight grooves 135 formed on the first rotation shaft 134a. In addition, in the upper and lower cases 112H and 112L of the LCD unit 110, as shown in FIG. 2, the speaker, the vibration motor 115, the earpiece holder and the like are mounted on the side of the groove 113.

Hereinafter, an operation relationship of the slide type mobile communication terminal configured as described above will be described.

The user positions the camera lens unit 131 in the opposite direction of the LCD 111, which is a basic position. Then, the camera lens unit 131 faces the subject, and photographs while looking at the LCD 111. On the other hand, when the user wants to photograph themselves, the camera 130 rotates 180 degrees so that the camera lens unit 131 faces itself. In this process, the FPCB 139 surrounding the second rotation shaft 134b is gradually loosened. In the rotation process of the camera 130, the latch plate 141 elastically deforms, and the protrusion 143 passes over eight grooves 135. That is, the user rotates the camera 130 by 8 clicks. The rotation angle corresponding to 8 clicks is 180 degrees. When the direction of the LCD 111 and the direction of the camera lens unit 131 are the same so that the camera 130 rotates to photograph itself, the magnetic force sensor 150 generates an electrical signal as described above. The screen of the LCD 111 is changed by the signal, and when the user looks at the LCD 111, the subject himself appears to be normally symmetric with himself. The user photographs himself in this state.

Meanwhile, in the shelf photographing mode, when the camera photographing is completed, the camera lens unit 131 is positioned to face the inner bottom surface of the groove 113 by rotating the camera 130. Then, the camera lens unit 131 may be closed by the upper and lower cases 112H and 112L of the LCD unit 110 to block contamination by external pollutants.

As described in detail above, the slide type mobile communication terminal provided with the rotating camera of the present invention has an advantage in that the camera is positioned in a groove formed at the upper end of the LCD to photograph front, rear, and up, and thus has an extended shooting range.

On the other hand, in the past, there has been developed a folding mobile communication terminal equipped with a rotary camera, the rotary camera used here is mounted to the hinge coupling portion of the folding mobile communication terminal. Therefore, it was difficult to mount a camera module larger than the hinge diameter. However, in the present invention, since the camera is mounted in a groove open at the top of the LCD in the slide type mobile communication terminal, the installation of the camera module does not occur even if the size of the camera module is increased. Recently, as the camera mounted on the mobile communication terminal implements optical zoom, the size of the camera is increasing.

On the other hand, the slide-type mobile communication terminal with a rotary camera of the present invention can be positioned so that the lens portion of the camera facing the inner side of the groove when not photographing to prevent contamination of the lens portion.

Although the technical idea of the slide-type mobile communication terminal with a rotary camera of the present invention has been described above with the accompanying drawings, this is by way of example and not by way of limitation of the present invention.
