The second camera module 18 mounted under the button module 30 is exposed for photographing or video communication. When it is not necessary to use, the keyboard board 30 can be first slid to the left to its initial position, and then the button module 30 can be rotated in the counterclockwise direction until it returns to the initial position. It can be understood that the keyboard device 20 can be mounted on the body 10 only in a manner of rotating relative to the body 10, and after the button module 30 is rotated, the second camera module 18 can be completely exposed. It can be understood that the keyboard device 20 can be directly disposed on the body 10. At this time, the fixing base 91 can be omitted, and the supporting column 93, the rotating shaft supporting portion 95 and the sliding shaft 97 are disposed on the body 10. In summary, the present invention complies with the requirements of the invention patent, and patents are filed according to law. The above is only the preferred embodiment of the present invention, and the scope of the present invention is not limited to the above-described embodiments, and equivalent modifications or variations made by those skilled in the art in light of the spirit of the present invention are It should be covered by the following patent application.
