The rotary folder-type mobile communication terminal of the present invention comprises: a body part 10 having a button-operating unit 11 disposed on the upper surface thereof; a folder part 20 having an LCD window 21 facing the body part 10; a rotating hinge part 30 comprising a hinge 31 and a fixing element 32 for rotatably connecting the body part 10 and the folder part 20; and a folding hinge part 40 for opening/closing the folder part 20. Between the body part 10 and the folder part 20 is disposed an auxiliary connection part 50. The rotating hinge part 30 is mounted to the folder part 20 and the auxiliary connection part 50. The folding hinge part 40 is mounted to the auxiliary connection part 50 while the folding hinge part 40 is spaced apart from the rotating hinge part 30. Specifically, the rotating hinge part 30 is mounted on a prescribed axis formed at the folder part 20 and the auxiliary connection part 50, and the folding hinge part 40 is mounted on another prescribed axis formed at the auxiliary connection part 50, which is different from the axis of the rotating hinge part 30. At the upper end of the auxiliary connection part 50 adjacent to the folding hinge part 40 is formed a cutout groove 51 such that the cutout groove 51 extends in the lateral direction of the auxiliary connection part 50 from one end of the folding hinge part 40. On the upper surface of the body part 10 inside the cutout groove 51 is formed a space part 60, on which is disposed a protrusion part 61. The upper end of the auxiliary connection part 50 is connected to the protrusion part 61 by means of the folding hinge part 40. The hinge 31 is mounted in the folder part 20, and the fixing element 32 is mounted in the auxiliary connection part 50. The rotating hinge part 30 is spaced apart from the folding hinge part 40 so that the space part 60 necessary for arranging large-sized parts, such as a camera having a great number of pixels, is sufficiently obtained. The folding hinge part 40 connects the auxiliary connection part 50 to the body part 1 while the folding hinge part 40 is spaced apart from the rotating hinge part 20. The folder part 20 is folded or unfolded by means of the folding hinge part 40 so that the folder part 20 is closed or opened. The cutout groove 51 is formed at the auxiliary connection part 50 such that the space part 60 is provided on the upper surface of the body part 10. The protrusion part 61 is disposed on the space part 60 of the body part 10 such that the protrusion part 61 is protruded upward in the cutout groove 51. Consequently, a large arrangement space sufficient to arrange a camera having a great number of pixels is obtained. Also, the fixing element 32 is mounted in the auxiliary connection part 50, and the hinge 31, which is preferably integrally formed with the fixing element 32, is mounted in the folder part 20. Consequently, a large arrangement space sufficient to arrange a camera having a great number of pixels is obtained through the provision of the space part 60, and thus the camera can be mounted in the rotary folder-type mobile communication terminal of the present invention without increasing the size and the thickness of the folder part 20. In other words, a large-sized camera can be easily mounted in the rotary folder-type mobile communication terminal through the provision of the space part 60, and the dimensional change of the folder can be minimized through the provision of the auxiliary connection part 50 so that the fixing element 32 is mounted in the auxiliary connection part 50 and the hinge 31 is mounted in the folder part 20. According to the present invention as described above, the folding hinge part 40 and the rotating hinge part 30 are mounted on different axes while the folding hinge part 40 and the rotating hinge part 30 are spaced apart from each other so that the space part 60 is provided, whereby the dimensional change of the folder is minimized. FIG. 3 is a perspective view, in part, of the rotary folder-type mobile communication terminal according to the preferred embodiment of the present invention showing the connection of essential components of the rotary folder-type mobile communication terminal, and FIG. 4 is a front view, in part, schematically showing the rotary folder-type mobile communication terminal shown in FIG. 3. The construction of the rotary folder-type mobile communication terminal according to the preferred embodiment of the present invention will now be described in detail with reference to FIGS. 3 and 4. At the folder part 20 is disposed a hinge-locating member 80 for securely locating the hinge 31 of the rotating hinge part 30, and at the auxiliary connection part 50 is disposed a fixing element-locating member 70 for securely locating the fixing element 32 of the rotating hinge part 30. Specifically, the fixing element-locating member 70 has an insertion groove 71 formed at the center thereof. The fixing element 32 of the rotating hinge part 30 is inserted in the insertion groove 71 of the fixing element-locating member 70. At both sides of the insertion groove 71 are formed engagement grooves 72 while the engagement grooves 72 are arranged symmetrically to each other. At the rear of the engagement grooves 72 are formed projection parts 73, respectively. Specifically, the projection parts 73 surround the engagement grooves 72, respectively. The fixing element-locating member 70 is provided at both ends thereof with fixing parts 74, respectively. The hinge-locating member 80 has an insertion tube 81 formed at the center thereof. The hinge 31 of the rotating hinge part 30 is fixedly inserted in the insertion tube 81 of the hinge-locating member 80. At one side of the insertion tube 81 is formed an engagement projection 82. The hinge-locating member 80 is provided at both ends thereof with fixing parts 83, respectively. The fixing element-locating member 70 is mounted in the auxiliary connection part 50 while the fixing element 32 is inserted in the insertion groove 71. The hinge-locating member 80 is mounted in the folder part 20 while the hinge 31 is inserted in the insertion tube 81. When the folder part 20 is rotated about the rotating hinge part 30 by 180 degrees, the engagement projection 82 of the hinge-locating member 80 mounted in the folder part 20 is engaged into one of the engagement grooves 72 of the fixing element-locating member 70 mounted in the auxiliary connection part 50. When the folder part 20 is further rotated about the rotating hinge part 30 by 180 degrees, the engagement projection 82 of the hinge-locating member 80 mounted in the folder part 20 is engaged into the other of the engagement grooves 72 of the fixing element-locating member 70 mounted in the auxiliary connection part 50. In this way, the folder part 20 is securely engaged with the auxiliary connection part 50. While the engagement projection 82 of the hinge-locating member 80 is engaged in the corresponding engagement groove 72 of the fixing element-locating member 70, the engagement projection 82 is securely held by means of the projection parts 73 of the fixing element-locating member 70. The fixing element-locating member 70 is securely fixed to the auxiliary connection part 50 by means of the fixing parts 74. Similarly, the hinge-locating member 80 is securely fixed to the folder part 20 by means of the fixing parts 83. FIG. 5 is a perspective view showing a fixing element-locating member of the rotary folder-type mobile communication terminal shown in FIG. 3, and FIG. 6 is a perspective view showing a hinge-locating member of the rotary folder-type mobile communication terminal shown in FIG. 3. The operation of the rotary folder-type mobile communication terminal according to the preferred embodiment of the present invention will now be described in detail with reference to FIGS. 5 and 6. The fixing element-locating member 70 and the hinge-locating member 80 are disposed in such a manner that the fixing element-locating member 70 and the hinge-locating member 80 contact each other while the engagement projection 82 of the hinge-locating member 80 is engaged in one of the engagement grooves 72 of the fixing element-locating member 70. When the folder part 20 is rotated about the rotating hinge part 30 by 180 degrees, the engagement projection 82 of the hinge-locating member 80 is engaged into the other engagement grooves 72 of the fixing element-locating member 70 so that the folder part 20 is securely engaged with the auxiliary connection part 50. Specifically, when the engagement projection 82 of the hinge-locating member 80 is rotated 180 degrees about the insertion tube 81 while the engagement projection 82 of the hinge-locating member 80 is engaged in one of the engagement grooves 72 of the fixing element-locating member 70, the engagement projection 82 of the hinge-locating member 80 is engaged into the other engagement groove 72 of the fixing element-locating member 70. Consequently, further rotation of folder part 20 is prevented. The fixing element 32 of the rotating hinge part 30 is securely inserted in the insertion groove 71 of the fixing element-locating member 70. The hinge 31 of the rotating hinge part 30 is securely inserted in the insertion tube 81 of the hinge-locating member 80, which faces the insertion groove 71 of the fixing element-locating member 70. When the engagement projection 82 of the hinge-locating member 80 is engaged into the corresponding engagement groove 72 of the fixing element-locating member 70, the engagement projection 82 contacts the projection parts 73 of the fixing element-locating member 70. As a result, the engagement projection 82 of the hinge-locating member 80 is securely held by means of the projection parts 73 of the fixing element-locating member 70. Consequently, whenever the folder part 20 is rotated 180 degrees clockwise or counterclockwise relative to the auxiliary connection part 50, the engagement projection 82 of the hinge-locating member 80 is engaged into the corresponding engagement groove 72 of the fixing element-locating member 70, whereby further rotation of the folder part 20 is prevented, and thus the folder part 20 is securely engaged with the auxiliary connection part 50. As apparent from the above description, the present invention provides a rotary folder-type mobile communication terminal that is capable of providing a large arrangement space sufficient to arrange a large-sized component, such as a large-sized camera having a great number of pixels, and related parts therein. Consequently, the present invention has the effect of mounting the large-sized component in the rotary folder-type mobile communication terminal without increasing the thickness or the size of a folder part of the rotary folder-type mobile communication terminal as compared to the conventional rotary folder-type mobile communication terminal. Furthermore, the rotary folder-type mobile communication terminal according to the present invention has a simple folder-holding structure for stably and securely holding the folder part after the folder part is rotated. Consequently, production costs of the rotary folder-type mobile communication terminal are reduced. Although the preferred embodiment of the present invention has been disclosed for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims.
