When the first rod portion overlaps with the second rod portion, the one of the rotation supporting devices is collapsed. When the first rod portion is not overlapped with the second rod portion, it is an unfolded state of the rotation support device. With the above structure, when the rotation supporting device is in the folded state, the rotation supporting device and the input device can be housed in the bottom case, and when the rotation supporting device is in the unfolded state, the input device is exposed to the casing and the second rod portion is used for Support the housing. Due to the novel construction of this creation, it can provide industrial use, and it has improved efficiency. Therefore, it applies for a new type of patent according to law. [Embodiment] The above and other objects, features and advantages of the present invention will become more apparent and understood. Hereinafter, please refer to FIG. 1 to FIG. 7 together with the first embodiment of the portable electronic device and the rotation supporting device thereof. First, please refer to FIG. 1 to FIG. 2b for various states of the portable electronic device and the rotation supporting device thereof. FIG. 1 is a schematic view showing the collapsed state of the first embodiment of the portable electronic device and the rotation supporting device thereof; FIG. 2a and FIG. 2b are the first embodiment of the portable electronic device and the rotating support device thereof. A collapsed state of an embodiment is converted to an expanded state. As shown in FIG. 1 to FIG. 2b, the portable electronic device 1 of the present invention comprises a screen 10, an input device 20, a housing 30 and a rotating support device 40. The middle housing 30 further includes a surface 31 and a bottom case 32. And the surface 31 is combined with the screen 10. The rotation support device 40 is respectively connected to the input device 20 and the housing 30_. The rotation support device 40 further includes a first rotation shaft 4, a second rotation shaft 42, a first rod portion 43, and a second rod portion 44, wherein the first rotation shaft 41 is connected. The bottom case φ 32 is connected to the first rod portion 43 and the second shaft 42 is connected to the first rod portion 43 and the second rod portion 44°. When the relative positions of the first rod portion 43 and the second rod portion 42 overlap, the rotation support device is The folding state of the 40 (as shown in FIG. 1 ), at this time, the rotation supporting device 40 and the input device 20 can be received in the bottom case 32 , which is the folded state of the supporting device 40 , and the first rod portion 43 includes the receiving space 431 . The second rod portion 44 can be accommodated. If the input device 20 is pulled in the direction indicated by the arrow in FIG. 1, the first rod portion 43 is slid relative to the housing 30, and the second rod portion 44 is slid relative to the first rod portion φ43. The portable electronic device 1 of the present invention is rendered in the state of FIG. 2a. It should be noted that the first rotating shaft 41 is located at A in FIG. 2a and FIG. 2b, and the second rotating shaft 42 is located at B in FIG. 2a and FIG. 2b. For the detailed interaction relationship between the first rotating shaft 41 and the bottom casing 32, please refer to 3 and FIG. 4, the detailed rotation relationship between the first rotating shaft 41 and the bottom case 32 is referred to FIG. 5, and the detailed connection relationship between the second rotating shaft 42 and the first rod portion 43 and the second rod portion 44 is shown in FIG. 7 is a schematic diagram of the unfolded state of the first embodiment of the portable electronic device and the rotation supporting device thereof, and the interaction relationship of each component will be described in detail in the following paragraph. 5 M416118 The enlarged view of A in FIG. 2a and FIG. 2b is shown in FIG. 3 to FIG. 5.
