BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a stylus receiving mechanism and a portable computer therewith, and more specifically, to a stylus receiving mechanism capable of bi-directionally receiving a stylus and a portable computer therewith.
2. Description of the Prior Art
In modern information society, portable electronic devices are widely used in every field. A large quantity of data is communicated, processed, and stored in digital data format, thus computers used for reading and accessing data have become very important tools. Especially portable computers such as notebooks, personal digital assistants (PDAs) and global positioning systems (GPS), which by their small size, lightness, and portability, help users to search, browse, and store various kinds of data at anytime at any place. Therefore, portable computers have become one of the most important digital data platforms and the focus of much development. Concerning portable computers, both compactness and usability of the human input interface are emphasized; therefore a touch panel is used as part of the man machine interface (MMI). When a user uses a stylus to touch or press on the touch panel, the touch panel can sense the position or even the strength of the stress and control the computer according to the associated command.
Conventionally, a slot is formed on a lateral side of the portable electronic device, and the stylus is disposed inside the slot. However, since the stylus is fixed to one side of the portable electronic device, it is inconvenient for the user, who is accustomed to this side, to take the stylus from another side. For example, if the stylus is fixed to the right side of the portable electronic device, a left-handed person has to take the stylus by his/her unaccustomed right hand. Furthermore, the design of a stylus fixing mechanism disposed on the portable electronic device enlarges its size and increases its manufacture cost. If the portable electronic device is designed for waterproof function, it might reduce waterproof effect due to leakage of the stylus fixing mechanism. Thus, design of a stylus receiving mechanism capable of receiving a stylus effectively and conveniently is an important issue nowadays.

In this embodiment, the stylus receiving mechanism 56 includes two blocking parts 68. The location and the number of the blocking parts 68 are not limited to this embodiment, and depend on actual design demand. Two blocking structures 681 are formed on two ends of the blocking part 68 respectively. Each blocking structure 681 can be an inclined structure, and the inclined directions of the two inclined structures can be opposite to each other. Therefore, the two blocking parts 68 block a clip 541 of the stylus 54 in the second direction (−X direction) or in the first direction (+X direction) to respectively prevent the stylus 54 from falling out of the second opening 582 or out of the first opening 581 when the stylus 54 passes through the first opening 581 in the first direction (+X direction) or passes through the second opening 582 in the second direction (−X direction) to be received inside the chamber 583 of the handle 58. Besides, two grooves 70 are formed on the inner wall of the upper casing 60 of the handle 58 and disposed on two sides of the blocking part 68 respectively for accommodating a keyswitch 542 of the stylus 54 when the stylus 54 passes through the first opening 581 in the first direction (+X direction) or passes through the second opening 582 in the second direction (−X direction) to be received inside the chamber 583.
Please refer to FIG. 8, and FIG. 8 is a cross-sectional diagram of the stylus receiving mechanism 56 receiving the stylus 54 according to the preferred embodiment of the present invention. As shown in FIG. 3 and FIG. 4, the fastening part 64 presses the stylus 54 in the third direction (+Y direction) for fastening the stylus 54 inside the chamber 583 after the stylus 54 passes through the first opening 581 in the first direction (+X direction) or passes through the second opening 582 in the second direction (−X direction) to receive the stylus 54 inside the chamber 58. Furthermore, the blocking part 68 blocks the clip 541 of the stylus 54 in the second direction (−X direction) or in the first direction (+X direction) to prevent the stylus 54 from falling out of the second opening 582 or out of the first opening 581. Besides, the keyswitch 542 of the stylus 54 can be accommodated in the groove 70 of the inner wall of the handle 58, so as to receive and fix the stylus 54 inside the chamber 583 of the handle 58 firmly by the aforesaid fixing structures. In the aforesaid embodiment, the fastening parts 64, the blocking structures 681 of the blocking parts 68, and the grooves 70, of the receiving mechanism 56, can be in a pair configuration of structural design. The fastening parts 64, the blocking structures 68 of the blocking parts 64, and the grooves 70, of the receiving mechanism 56, even can represent a symmetrical structural design, so as to achieve the bidirectional stylus receiving mechanism when the stylus 54 passes through the first opening 581 in the first direction (+X direction) or passes through the second opening 582 in the second direction (−X direction). Such that the handle 58 can receive the stylus 54 in a bidirectional way, it provides the convenience of operation for both right-handed users and left-handed users.
Moreover, please refer to FIG. 1 and FIG. 2, in order to prevent the missing of the stylus 54, the portable computer 50 can further include a connecting part 72 connected to an end of the stylus 54 and a side of the host 52.
