Detailed ways

The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

As shown in FIG. 1 , the present invention is a multi-page turnable tablet, which includes a handwriting input sensing layer and a substrate 2 with a control device inside, and the sensing layer is arranged on the substrate 2 . The sensing layer is more than one sensing page 1, and one side of the sensing page 1 is connected to the substrate. The settings of the sensing area 12, function keys 13 and shortcut keys 14 on each sensing page 1 are different. For example, web pages, writing pages, chatting pages, drawing pages, etc. each have their own sensing areas, function keys or shortcut keys.

As shown in Figures 1 and 2, the connection between the sensing page 1 and the substrate 2 of the present invention is a loose-leaf connection. Of course, the connection between the sensing page 1 and the substrate 2 can also be a book-like bonding, or a hinge-like pivoting connection. When a specific page needs to be used, it can be turned page by page just like a book.

As shown in FIGS. 1 and 2 , in order to protect the sensing page 1 , a tablet protection upper cover 3 is provided on the sensing page 1 , and the upper cover 3 and the base plate 2 are hingedly connected.

Further, since the induction area 12, function key 13 or shortcut key 14 of each page induction page 1 is different, such as going up a web page, writing page, chatting page, drawing page, etc., in order to facilitate the computer to cooperate with different function pages, switch different driving , the handwriting board is provided with a page turning sensor 4, the output terminal of the page turning sensor 4 is connected to the page detection circuit in the control device, the output of the page detection circuit is to the encoder, and the output of the encoder is connected to the CPU in the control circuit through the bus . Corresponding to different sensing pages, after the CPU obtains the detection and identification information, it can automatically switch the driver so as to correspond to the function of the current sensing page. In order to identify each sensing page, the page turning sensor 4 can be divided into a first part and a second part that cooperate with each other, and the first part of the page turning sensor can be arranged on the substrate 2 or on the sensing page 1, and the corresponding , the second part of the page turning sensor is arranged on the sensing page 1 or the substrate 2 .
