Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to an input device of a portable computer, which mainly comprises a keyboard, a top cover, a support base, and a communication connection unit. The most convenient and quickest way to enter information into a portable small computer on a communication connection unit or into a personal digital assist system, and the top cover can be removed and turned back. It is a compact, space-saving, portable user input device that is user-friendly and easy to use.

[0002]

[Prior art]

 With the development of computer technology, computer-related products have become indispensable in our lives. The most common type is a small portable computer or a personal digital assist system, but handwriting input, which is one of the conventional input methods, always requires a large number of characters to be input. It puts a heavy burden on those who work. In addition, an easy-to-use external portable keyboard is needed to input large numbers of characters conveniently and quickly.

[0003]

[Problems to be solved by the invention]

 Conventional external portable keyboards are generally divided into foldable keyboards and portable keyboards that are not. Foldable keyboards are small in volume after folding, making them convenient to carry. However, the internal circuit is liable to break down because it folds or falls every time it is used. Foldable portable keyboards are by no means ideal for those who work long hours typing large numbers of characters.

[0004] Furthermore, ordinary portable keyboards do not cause failures as frequently as foldable keyboards, but because of their large volume, there seems to be room for improvement. Generally, when the portable computer is placed on the keyboard, the center of gravity of the keyboard itself is not stable. For this reason, the portable keyboard has a support to stabilize the center of gravity of the portable keyboard attached to the portable small computer. The commonly used columns are built into the portable keyboard. Inevitably, the thickness of the keyboard itself increases, and its compactness is far from ideal.

[0005] Further, the upper cover of the conventional portable keyboard is connected to the support base and the communication connection unit to be integrated. That is, the upper cover, the support pedestal, and the communication connection unit are connected to form one support unit. When using a portable small computer or a personal digital assistant system (PDA), the top cover cannot be easily removed, so take up space and inadvertently touch the top cover when operating, the keyboard may be turned over In the worse case, there is a risk that the support base and the communication connection unit may be damaged.

Further, in the conventional portable keyboard, the communication connection unit and the signal transmission of the keyboard portion use a conductor. According to the method of transmitting a signal through the conductor, the conductor itself is large in volume, and is limited to a portable small computer that transmits simple information data or a PDA, and a relatively complicated portable type that requires a constant transmission speed. Not applicable to computers or PDAs.

[0007]

[Means for Solving the Problems]

 The input device of the portable computer of the present invention includes a keyboard, a top cover, a support base, and a communication connection unit. The keyboard has an opening at the top, and the shaft extends inward on both sides. There are protrusions on the two axes. The bottom surface of the keyboard is a flat surface on which several keys are arranged. If necessary, provide a fixing groove in the plane. Also, make a recess at the bottom of the keyboard. The recess has several shaft holes, so that the support plate can be folded back in combination with a support plate having several shafts. The top lid has an opening. At the edge of the opening there is a tank for sliding. There are two hooks at the entrance of the opening. There is a fixing protrusion on the edge of the top lid, which corresponds to the fixing groove in the plane of the keyboard. The top lid can be placed on any of the four sides of the keyboard to match the contour of the keyboard rim. The support pedestal has a bottom seat. The bottom seat has a plate extending upward to support it. The outside of the supporting plate has a protruding edge. There are stoppers on both sides of the bottom seat lower part. The communication connection unit includes a communication connection device. A flexible printed circuit board (FPC) is provided between the communication connection device and the keyboard, and is used for transmitting and receiving signals. The communication connection unit and the support pedestal are combined to form a shaft hole according to the outer shape of the communication connection unit, and the shaft holes simultaneously correspond to both axes of the opening of the keyboard. The trough for sliding the top cover corresponds to the protruding edge of the support pedestal. Then, the hooks of the upper lid are fixed to both axes of the opening of the keyboard. Further, the protrusions on both axes of the opening of the keyboard are stopped by stoppers of the support base. Since the corresponding positions of the projection and the stopper are different, the angle between the plane of the keyboard and the support pedestal is also different.

[0008]

[Action]
