DETAILED DESCRIPTION OF THE INVENTION Reference will now be made in detail to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings. Now changing to Figure 1, which is a plan view illustrating a mobile terminal 1 according to a first embodiment of the present invention. As shown in Figure 1, the mobile terminal 1 includes a first body 10 and a second body 20 connected to one another such that the second body 20 can be rotated horizontally on the first body. In more detail, the mobile terminal 1 includes a hinge module 30 installed in the upper right corner between the first and the second body 10 and 20 in such a way that the second body 20 can be rotated horizontally. In addition, the location of the hinge module 30 advantageously allows a large open area to exist in the first body 10. Note that the location of the hinge module 30 may also be in the corner upper left between the first and second bodies 10 and 20. In addition, the right and left sides refer to the right and left directions in Figure 1 and the upper and lower sides refer to the upper and lower directions in Figure 1 Furthermore, as shown in Figure 1, the second body 20 has a smaller length than the first body 10 such that when the second body 20 is closed with respect to the first body 10, a portion of the first body is exposed. 10. In addition, a keyboard 12 is formed in the exposed portion. The mobile terminal 1 also includes a microphone 15 at the lower front end of the first body 10, and first and second horns 23 and 24 at the upper and lower front ends of the second body 20, respectively. The second body 20 also includes a display 21. Accordingly, the user can receive or make another incoming or outgoing call from a third party using the keypad 12, the microphone 15, and the horns 23 and 24 without opening the second body 20. In addition, when the second body 20 is rotatably open, the first horn 23 also rotates, thereby providing the user with a stereo sound by networking with the second horn 24. In more detail, Figure 2 is a plan view illustrating the second body 20 which is in an open state after having been rotated 90 ° clockwise from the closed state illustrated in Figure 1. As shown in Figure 2, the mobile terminal 1 also includes the keyboard 11 formed on the front surface of the first body 10. As shown, the keyboard 11 is exposed when the second body 20 is rotated 90 °. The keyboard 12 is also exposed (i.e., the keyboard 12 is always exposed). In addition, the first keyboard 11 includes a plurality of keys with numbers, characters in English, etc., which the user can select to capture information. The keypad 12 includes arrow keys, a send key, a menu key, a search key, etc., which the user can use to select a particular function or menu. Accordingly, the user can receive or make another incoming call or outgoing call from a third party using the first keypad 11 and / or the keypad 12 when the second body 20 is rotatably open. In addition, the keypads 11 and 12 may be a keyboard of the type that is pressed operated in a pressure form or a touch-sensitive keyboard operated in a tactile manner. Accordingly, and with reference to Figures 1 and 2, because the hinge module 30 is eccentrically disposed in the upper right corner between the first and second bodies 10 and 20, the keyboard 11 has a relatively large area. That is, the rotating mobile terminals of the related art include a hinge module placed in the central part of the mobile terminal, which reduces the amount of area available for the keyboard in the first body. In addition, the hinge module 30 is disposed in such a position that when the first and second bodies are in a closed position as in Figure 1, the upper portions of the first and second bodies 10 and 20 coincide with each other. This type of configuration forms a bar-type mobile terminal. Further, as shown by the dotted line in Figure 2, when the second body 20 is rotated, the side edge portion of the second body 20 is higher than the upper edge portion of the first body 0, thereby forming a mobile terminal in the form of T. In addition, the screen 21 displays a vertical screen when the second body 20 is closed with respect to the first body 10, as shown in Figure 1 and displays a horizontal screen when the second body 20 is opened with with respect to the first body 10 as shown in Figure 2. In the open state, the user can easily carry out an edit operation in text transmission mode, enjoy a video in the VOD mode, or a television program in the mode diffusion, etc., on the screen 21. Now changing to Figures 3 and 4, which are a diagrammatic side view and an assembled side view, respectively, illustrating the mobile terminal shown in Figure 1 and in Figure 2. As shown, the mobile terminal 1 includes a keypad mounting portion 17 for mounting the keypad 12 which is always exposed (i.e., when the second body 20 is open and closed). Also included is another keypad mounting portion 16 disposed immediately below and below the mounting portion of the keyboard 17 for mounting the keypad 16. Accordingly, as shown in Figure 4, the second body 20 is internally mounted from the second. keyboard assembly portion 17 and this way is mechanically stable Also note that in Figure 4 an upper surface of the second body 20 is higher than an upper surface of the first body 0 (ie, higher than an upper surface of the keyboard mounting portion 17 of the first body 10). Next, Figure 5 is a side view illustrating a mobile terminal 90 according to another embodiment of the present invention. In this embodiment, an upper surface of a second body 92 of the mobile terminal 90 has the same height as the upper surface of the keyboard mounting portion 96 for mounting a mounting keyboard 95. Figure 5 also illustrates a mounting portion. of keyboard 94 for mounting another keyboard 97 and a hinge module 93. Accordingly, with the configuration shown in Figure 5, mobile terminal 90 has a simpler appearance and better stability. Turning now to Figures 6-8, they are diagrammatic views of the hinge module 30 shown in Figures 1 and 2. As shown in Figures 6 and 8, the hinge module 30 includes first and second hinge members 31 and 32 configured to be installed in parallel and formed inside a plate. The first hinge module 31 is formed on the upper surface of the first body 10 and the second hinge module 32 is formed on the lower surface of the second body 20 in a position corresponding to the first body 10. Figures 6 and 8 also illustrate the second hinge member 32 having an axis 33 disposed perpendicular to the first and second hinge members 32. The shaft 33 also supports the first hinge member 31 such that the first hinge member 31 is horizontally rotatable with respect to the second hinge member 32. Also, as shown in Figures 7 and 8 , the first and second hinge members 31 and 32 and the shaft 33 have a hole through which a connector for electrically connecting the first and second bodies 10 and 20 passes. In addition, a mechanism of elastic force is provided between the first and second hinge members 31 and 32 to thereby provide an elastic force in a rotational direction when the first hinge member 31 is rotated with respect to the second hinge member 32. In greater detail, as shown in the Figures 7 and 8, the spring force mechanism includes a fixed cam 40, fixed to the first hinge member 31. The fixed cam 40 also includes a cam profile formed on an outer circumferential surface thereof. The spring force mechanism also includes the cams 50A and 50B and a spring 80 installed around the cams 50A and 50B. In the example shown in Figure 4, the cam 50A is movable while the cam 50B is not. The spring 80 elastically provides a rotational force to the cam 50A. That is, the cam 50A is linearly movable in a radial direction around the fixed cam 40 on the first hinge member 31 such that the second body 20 can be rotated with respect to the first body 10. In more detail the profile of the fixed cam 40 is formed at a 90 ° angle in the clockwise direction of the watch from a closed position of the second body 20 such that the second body 20 stops in its closed position and in its open position after being turned 90 °. In addition, as shown in Figure 8, the fixed cam 40 includes a first curved portion 41 and a second curved portion 42 on the outer circumferential surface thereof. The first curved portion 41 is bent to stop the second body 20 in the closed position and the second curved portion 42 is formed to stop the second body 20 in its open position. That is, the first and second curved positions 41 and 42 of the fixed cam 40 interact with the movement cam 50A to stop the second body 20 both in its open and closed positions. Furthermore, in the above description, only the first cam 50A is movable. However, if the profile of the fixed cam 40 is formed to center in a double symmetric fashion on the axis 33, the second movement cam 50B can also be installed to be movable in the radial direction. In addition, as shown in Figures 7 and 8, the first movement cam 50A includes a protrusion which stops the projection 51 coming into contact with the profile of the cam on the fixed cam 40, and a rotary wheel 52 provided at the stopping protrusion 51. In this way, the movement cam 50 moves along an upper portion of the profile of the fixed cam 40 in such a way that the second body 20 can be rotated 90 ° with respect to the first body 10. In addition, the rotary wheel 52 reduces a frictional force of the movement cam 50A and thus the second body 20 can be gently rotated. Figures 6-8 also illustrate the hinge module 30 that includes a guide portion 70 formed between the second hinge member 32 and the first movement cam 50A. The guide part 70 is configured to allow the first movement cam 50A to move linearly towards and away from the axis 33 (or the fixed cam 40). In more detail, the guide portion 70 includes a groove-like guide channel 72 formed in the second hinge member 32 and a guide protrusion 71 formed in the first movement cam 50A. In this way, the guide protrusion 71 slides within the guide channel 72. In addition, the guide portion 70 is preferably disposed at both ends of the first movement cam 50A to prevent the first movement cam 50A from shaking when the cam 50A does it move. In addition, the spring 80 is formed to surround the first and second cams 50A and 50B such that the spring 80 can be easily assembled. However, because the spring 80 only needs to provide an elastic force to pull the first and second cam 50A and 50B toward each other, the spring 80 can also be formed to connect both ends of the first and second movement cams 50A and 50B such that the cams 50A and 50B come together. In addition, Figures 6-8 further illustrate the hinge module 30 that includes a stop portion 60 provided between the second hinge member 32 and the fixed cam 40 to allow the first hinge member 31 to stop in a stop position. exact with respect to second hinge member 32. As shown, the stopping portion 60 includes an arc-shaped guide channel 62 in the second hinge member 32 and a stopping protrusion 61 projecting from the fixed cam 40. The length of the channel guide 66 corresponds to the available rotation angle of the second body 20. An operation of the hinge module 30 will now be described with reference to Figures 9-11. In more detail, Figure 9 illustrates a state in which the second body 20 closes with respect to the first body 10. As shown, the stopping protrusion 51 of the first movement cam 50A and the rotary wheel 52 are stopped at the first curved portion 41 of the fixed cam 40. As shown in Figure 10, when the second body 20 is rotated slightly clockwise, the fixed cam 40 is rotated in the opposite direction and the first cam 50A moves in a direction away from the second cam 50B. In addition, since the fixed cam 40 is being rotated, the stopping protrusion 51 and the rotating wheel 52 pass an existing dead point between the first and second curved portions 41 and 42. At this time, the first cam 50A moves further. near the second cam 50B by virtue of the elastic force of the spring 80. In this way, the second body 20 is automatically rotated in the direction in which it was initially rotated. In addition, as shown in Figure 11, when the stopping protrusion 51 and the rotating wheel 52 reach the second curved portion 42, the second body 20 stops rotation.

Turning now to Figure 12, it is a plan view illustrating an open state in a mobile terminal 100 according to a second embodiment of the present invention. As shown, the mobile terminal 100 includes a first body 110, a second body 120 and a hinge module 130. The hinge module 130 is disposed in the upper right corner between the first and second bodies 110 and 120 and is configured to allow the second body 120 to rotate 90 ° and 180 ° with respect to the first body 110. Figure 12 illustrates the second body 120 being rotated 180 ° with respect to the first body 110. Furthermore, as shown in Figure 12, the mobile terminal 110 includes a first keyboard 1 which is exposed when the second body 120 is rotated 90 °, a second keyboard 112 is always exposed, and a third keyboard 113 which is exposed when the second body 120 rotates 180 °. The first and second keypads 111 and 112 carry out the same roles as keyboards 11 and 12 in the first embodiment of the present invention. The third keyboard 113 is preferably a directional keyboard that includes directional arrows. The mobile terminal 100 also includes a screen 121 in the second body 120, speakers 123 and 124 and a microphone 115 (similar to the first embodiment). In this way, when the second body 120 rotates at 90 ° and 180 °, the screen 121 displays both horizontal and vertical screens. For example, when the second body 121 rotates 90 ° in a manner similar to the first embodiment, the display 121 is horizontal and the first keyboard 11. In this way, the user can carry out an editing operation, etc., using the first keyboard 111 and displaying the screen 121 horizontally. Then, when the second body rotates another 90 ° (that is, a total of 180 °), the third keyboard 113 is also exposed and the screen 121 is vertical and slightly moved to the right part of the first body 110. In this way, in this instance, the user can play games or carry out a search operation using the arrow keys on the third keyboard 113. Next, Figure 13 is a plan view illustrating the hinge module 130 of the mobile terminal in Figure 12. As shown, the hinge module 130 includes a first movement cam 150A installed to be linearly movable with respect to a fixed cam (not shown in Figure 13). The hinge module 130 also includes a stopping portion 160 having a guide channel 162 with a radius (length) of about 180 ° and a stopping protrusion 161 configured to cause the second hinge member 132 to stop at exactly the point of rotation of 180 ° with respect to a first hinge member (not shown). Further, as shown in Figure 14, an outer surface of a fixed cam 140 includes a first curved portion 141 configured to capture the movement of the cam 150 when the second body 120 is closed with respect to the first body 10, a second curved portion 142 configured to capture the movement of the cam 150 when the second body 120 is rotated by 90 °, and a third curved portion 143 configured to capture the movement of the cam 150 when the second body rotates 180 °. In addition, similar to the first embodiment, the hinge module 130 also includes a second cam 150B, a stopping protrusion 151, a rotating wheel 152 and a spring 180. An operation of the hinge module 130 will now be described with respect to Figures 14-18. As shown in Figure 14, when the second body 120 is closed with respect to the first body 110, the stopping protrusion 151 and the rotating wheel 152 are connected in the first curved portion 141 of the fixed cam 140. As shown in FIG. Figure 15, when the second body 120 rotates slightly according to the clockwise, the first cam 150A moves in a direction away from the second cam 150B. further, as in the first embodiment, when the fixed cam 140 is being rotated, the stopping protrusion 151, and the rotary wheel 52 pass a dead point existing between the first and second curved portions 141 and 142. At this time, the first cam 150A moves closer to the second cam 150B by virtue of the spring force of the spring 180. In this way, the second body 120 is automatically rotated in the direction in which it was initially rotated. Figure 16 illustrates the stopping protrusion 151 and the rotating wheel 152 connecting to the second curved portion 142 such that the second body 120 stops rotating. In addition, as shown in Figure 17, when the second body 120 is slightly rotated additionally in the clockwise direction, the stopping protrusion 151, and the rotating wheel 152 passes into a dead point existing between the second and third curved portions 142 and 143. At this time, the first cam 150A moves in a direction closer to the second cam 150B through the spring force of the spring 180. In this way, the second body 120 is automatically rotated in the direction in which the second body 120 was initially rotated. Furthermore, as shown in Figure 18, the stopping protrusion 151 and the rotating wheel 152 then connect to the third curved portion 143 such that the second body 120 stops rotating. Turning now to Figure 19, it is a plan view illustrating a mobile terminal 200 according to a third embodiment of the present invention. As shown, the mobile terminal is in an open state when the second body 200 is rotated 90 ° in the counter-clockwise direction with respect to the first body 2 0. In this state, the screen 221 is a horizontal screen so the image can be displayed horizontally and not inverted. As in other embodiments, the mobile terminal 200 also includes speakers 223 and 224, a first body 210, keyboards 211 and 221, microphone 215, and a hinge module 230. In addition, a cam profile on the fixed cam in the module Hinge 230 is formed in both directions in such a way that the second body 220 can be turned counterclockwise to open and then in the direction of the clock hands to close. Next, Figure 20 is a control block diagram of the mobile terminal according to an embodiment of the present invention. As shown in Figure 20, the mobile terminal includes a controller 85 for changing a mode of the terminal according to a rotational direction and / or an angle of the second body. Also included is at least one sensor 86 for sensing the rotational direction and angle of the second body and for transmitting a corresponding signal to the controller 85. The sensor 86 is positioned to be able to detect the rotational direction of the second body angle. For example, the sensor 86 may be provided between the first and second bodies. In addition, the sensor 86 is preferably Hall impact that can sense a magnet (not shown) in one of the first and second bodies. Accordingly, when the sensor 86 perceives the rotational direction and / or the angle of the second body, the sensor 86 transmits a corresponding signal to the controller 85 and the controller 85 changes the corresponding display mode of the mobile terminal. For example, the controller 85 may change an image displayed on the screen 87 from a horizontal screen to a vertical screen or a vertically inverted image. The mobile terminal described with respect to Figure 20 can be applied to any embodiment of the present invention described above. Turning now to Figure 21, it is a flow chart illustrating a method for changing a screen mode of the mobile terminal of according to one embodiment of the present invention. Figure 20 will also be referred to in this description. As shown in Figure 21, the mobile terminal is in a standby state when the second body is closed on the first body (S10). The controller 85 then determines whether the second body has rotated (S12). If the second body has rotated (Si in S12), the sensor 86 perceives the direction of rotation and the angle of rotation of the second body (S14). The controller 55 then determines whether the angle of rotation is 90 ° in the clockwise direction (S16). For example, Figure 2 illustrates the second body 20 being rotated 90 ° in a clockwise direction. If the rotation angle is 90 ° in the clockwise direction (If in S16), the controller 85 changes the mode of the terminal in a TV reception mode (S18). If the angle of rotation is not 90 ° in one direction in a clockwise direction (Not in S16), the controller 85 determines whether the angle of rotation is 90 ° counterclockwise (S20). If the angle of rotation is 90 ° in the counterclockwise direction (If in S20), the controller 85 changes the mode of the terminal in the Game mode (S22). If the angle of rotation is not 90 ° counterclockwise (Not in S20), the controller 85 determines whether the angle of rotation is 180 ° (S24). If the angle of rotation is 180 ° (If in S24), the method returns to step S10. Otherwise (Not in S24), the method returns to step S14. In addition, the particular mode to which the terminal is automatically changed by the controller 85 can be stored previously and no additional manipulation of the keys by the user is necessary. In this way, the user can automatically change the terminal to various desired modes according to a rotation of a second body by changing the particular mode stored in the memory as necessary. In addition, the particular mode may be at least one of standby mode, and call mode, and text transmission mode, etc. As described so far, the mobile terminal and the method for changing the mode according to the embodiments of the present invention have many advantages. For example, a portion of the first body that is exposed when the second body is open is lengthened because the hinge module is arranged to be eccentric to one of the left or right sides between the first and second bodies. Accordingly, a larger keyboard can be installed in the exposed portion of the first body. In this way, the mobile terminal can be better used. In addition, because the direction of the image displayed on the screen is automatically changed by the rotation of the second body, an optimal screen is provided so that the user can enjoy a video or watch television. Since the present invention can be represented in various forms without departing from the spirit or essential characteristics thereof, it should also be understood that the modalities described above are not limited by any of the details of the foregoing description, unless it is specified what contrary, but rather should be widely constructed within its spirit and scope as defined in the appended claims, and therefore all changes and modifications that fall within the assignments and limits of the claims, or equivalences of such assignments and limitations therefore, are intended to be encompassed by the appended claims .
