Abstract: A method for manufacturing a case of an electronic device includes the following steps. First, a vacuum formed film is formed on a first mold, and the vacuum formed film has a first surface and a second surface. Then, an electromagnetic shielding layer is formed on the first surface. Afterwards, a patterned film and the vacuum formed film are provided in the second mold, and an in-mold decoration injection molding process is performed to form a case body between the second surface and the patterned film.

Abstract: A button device, which is disposed beside a display unit, comprises at least a button unit. The button unit includes a first part, a second part, and a third part. In this case, the second part is adjacent to the first part. At least a light beam emitted from the display unit passes through the second part. The third part faces the first part. At least a light beam passing through the second part is transmitted to the third part, and then the light beam transmitted to the third part is reflected by the third part and passes through the first part.

Abstract: An overturn structure used in a dual-usage computer comprises a display panel and a base member for enabling the display panel and the base member to be rotated relative to each other to change the computer between the notebook computer mode and the tablet PC mode is disclosed to include two first knuckles fixedly provided at a lateral side of the display panel, two second knuckles fixedly provided at a lateral side of the base member, and two coupling devices each having a first pivot respectively pivoted to the knuckles at the display panel and a second pivot respectively pivoted to the knuckles at the base member and a connecting member connected between the first pivot and the second pivot to hold the first pivot and the second pivot in parallel.
