Description of the Invention: [Technical Field of Invention] 3 Field of the Invention The present invention relates to a folding electronic device for use in a mobile phone, a notebook type personal computer, an electronic notebook, a DVD display, a remote control, and the like Two sets of single-axis hinged biaxial hinge devices are arranged in parallel with the rotating mechanism portion. [" '才支冬恃】 Background of the Invention 10 In general, a two-fold type mobile phone includes a structure in which a single-axis hinge device is combined with a first frame provided with a keyboard and a display image is loaded. In the second housing of the liquid crystal display (LCD), the switching operation of rotating the second housing (LCD side) is performed centering on the axis of the single-axis hinge. The two-fold type mobile phone further includes a configuration in which a biaxial hinge of a structure in which two axes are crossed by 15 is combined with the first frame and the second frame, whereby the first frame and the first frame are combined with each other. The second frame can be opened and closed by one of the single-axis hinges, and the second frame of the liquid crystal display can be rotated by another single-axis hinge orthogonal thereto. Further, in the two-fold type mobile phone as shown in Fig. 17, the single-axis hinge system that connects the first and second frames and the second frame and is switchable is disclosed as follows: the shaft 100 is punched and compressed. In the coil spring 101, the torque generating portion including the rotating cam 103 and the fixed cam 104 is provided at both ends of the compression coil spring 101, whereby high durability, downsizing, and weight reduction can be achieved (for example, reference) Patent Document 1). 5 1308943 The three-fold type mobile phone as described above is a structure in which a single uniaxial hinge is attached between the second frame and the second frame to perform a switching operation, so that a single-axis hinge is used as a center. When the switch is operated, in order to avoid conflict between the i-frame and one of the second frames, a rotary brake mechanism that can limit the rotation angle to -5 degrees is provided. The rotary brake mechanism is called a so-called frame brake mechanism. At the same time, the protrusion 3 is provided to be in contact with the first body and the second frame provided with the hinge, and the third frame is abutted to restrict the second frame and the second frame. The switching angle of the second frame. ► Therefore, the two-fold type mobile phone is usually set to 10 by the frame brake mechanism so that the second frame is 180 with respect to the first frame. The following rotation angles are used when they are turned on. In such a two-fold type mobile phone, the second frame structure can be approximated to approximately 360 with respect to the first frame. Rotate within the angular range or rotate the first frame and the second frame 180. In the state of the state, there is a strong demand for the diversification of the open state and the increase of the degree of freedom of the rotary motion.
