[1] [Technical field]

[2] The present invention relates to a cover device that can be combined with office and learning appliances, and more particularly to a picture, a video image, an electronic photo album, a photo, etc. that can be rotated to view two different formats and different angles in a vertical format or a horizontal direction. A cover device with a rotatable handheld or digital audiovisual mechanism.

[3] [Background]

[4] With the development of digital technology, electronic digital products such as PDAs, electronic photo albums, digital cameras and MP4s have been widely used in people's lives. These digital products are small in size, portable, and People are favored by the large amount of data storage and the characteristics of pictures and texts. This type of portable digital product caters to the rapid development of modern information technology and meets the needs of people in office, study and life.

[5] However, various digital products have certain conditions and limitations. For example, the most popular digital products such as PDAs, electronic photo albums, electronic digital cameras and MP4s are miniaturized, mobile and portable, so their size is bound to be limited, especially for color LCD screens. People naturally hope that the bigger the better, but in reality they are limited by the volume of the product. At present, the display screens of popular handheld computers (PDAs), electronic photo albums and MP4s on the market are all rectangular, and the displayed images have vertical and horizontal browsing formats, and people can realize the two formats through software. Conversion, but if the device such as a handheld computer is a stand-alone stand-alone machine, it can still be adapted to different formats by rotating the device, but if the handheld computer or the like is integrated with the cover device, such as 200410015427.5

No. disclosed in the Chinese invention patent

Multi-functional cover devices, etc., which combine the traditional folder with the PDA device to achieve the complementary advantages, but the position of the PDA device on the cover is fixed, while the picture on the cover is somewhat vertical. Some are horizontal, limited by the size of the screen, and the horizontal view of the screen with a vertical screen will be small, and vice versa. This can not be further illustrated by the following examples;

[6] For example, the 3.5-inch vertical screen display has a screen size of 71 (height) X53.4 (wide), and the full-screen display has a utilization rate of 100% for the vertical picture; when the horizontal picture is displayed, only 40 (high) X53 can be displayed for the full screen. .4 (wide), the screen display utilization rate is only 75%, which is only equivalent to the display effect of the 2.6-inch screen.
