Referring to
Particularly, since the user operates the game by directly pressing the control buttons 3220 on the input device 3200, the user can enjoy a control sense as that of using a general joystick. Namely, purchasing of an additional joystick is unnecessary, and plug/unplug operations of the joystick are avoided, which not only saves money, but also has an excellent convenience. On the other hand, since the touch pad 3210 and the control buttons 3220 are integrated to the input device 3200, number of accessories of the portable computer 3000 can be reduced. When the input device 3200 is not used, it can be disposed in the accommodating space 3112 to prevent losing the input device 3200. Moreover, according to a design of the wireless transmission, a distance between the user and the host 3100 can be increased, so as to protect eyesight of the user.
In the present embodiment, the host 3100 of the portable computer 3000 includes a base 3110, a display device 3130 and a withdraw device 3140. The accommodating space 3112 is disposed on the base 3110, and a bottom surface of the accommodating space 3112 has a plurality of concave areas 3112a. When the input device 3200 is disposed in the accommodating space 3112, the touch pad 3210 is exposed outside the base 3110, and the control buttons 3220 are accommodated into the concave areas 3112a. The display device 3130 is pivotally connected to the base 3110, so that the display device 3130 can be opened and closed relative to the base 3110. However, the portable computer 3000 can also apply a flat panel design. Namely, the host 3100 is not limited to be divided into the pivotally connected base 3110 and the display device 3130. Certainly, in other designs, the host 3100 can be divided into more parts.
The withdraw device 3140 is disposed aside the accommodating space 3112 for withdrawing the input device 3200 from the accommodating space 3112. In the present embodiment, the withdraw device 3140 for example has a press design. When the user is about to fetch the input device 3200, he may just press the withdraw device 3140, and the withdraw device 3140 can prop up the input device 3200 from the accommodating space 3112, which is quick and convenient. Certainly, the withdraw device 3140 can also have other suitable designs which are not described herein. Alternatively, a notch (not shown) can be maintained around the accommodating space 3112, so that the user can directly fetch the input device 3200 via the notch.
Moreover, the host 3100 also has a plurality of first contacts 3150 disposed in the accommodating space 3112, and the input device 3200 has a plurality of second contacts 3260 corresponding to the first contacts 3150. When the user disposes the input device 3200 into the accommodating space 3112, the first contacts 3150 in the accommodating space 3112 contact the second contacts 3260 on the input device 3200. Now, the host 3100 can supply power to the input device 3200 for charging the input device 3200. Charging the input device 3200 by using the host 3100 can save a cost of purchasing an external charger, which can both save the power and the money.
Selectively, the host 3100 can also have a non-contact charging module 3160 for charging the input device 3200. By applying the non-contact charging module 3160, no contact is required to be allocated on the host 3100, and the input device 3200 can be directly charged by just putting the input device 3200 into the accommodating space 3112. In the present embodiment, the non-contact charging module 3160 is, for example, an electromagnetic induction-type non-contact charging module, which applies electromagnetic induction and power conversion techniques to implement the charging. By applying the non-contact charging module 3160 to perform the charging, problems caused by poor contact of the terminals can be avoided. Though in the present embodiment, the host 3100 can perform the contact charging or the non-contact charging to the input device 3200, only one of the two charging methods is required to be selected and applied to the portable computer 3000, or the input device 3200 can be charged via the external charger (not shown).
In detail, the input device 3200 further includes a first part 3240 and two second parts 3250. The first part 3240 has a first surface 3242 and an opposite second surface 3244, wherein the touch pad 3210 is located on the first surface 3242, and the control buttons are located on the second surface 3244. The second parts 3250 are pivotally connected to two side edges of the first part 3240, respectively, and the second parts 3250 are suitable for being rotated to close to or depart from each other. In
When the user uses the input device 3200 to play the game, the two second parts 3250 can be rotated outwards as that shown in
The control buttons 3220 include a direction key 3222, a plurality of function keys 3224 and a plurality of setting keys 3226. The direction key 3222 is used for controlling directions. When the user presses the direction key 3222, a corresponding control signal is generated for controlling a moving direction of a main object of the computer game. The function keys 3224 are, for example, four keys arranged up and down, left and right. When the user presses one of the function keys 3224, a control signal is generated and transmitted to the host 3100 for executing a specific function corresponding to the function key 3224, for example, jumping, attacking, menu switching, accelerating, etc. The setting keys 3226 are, for example, setting keys corresponding to setting functions of the game. For example, when the user presses one of the setting keys 3226, a control signal is generated to control pausing or starting of the game.
Moreover, the input device 3200 further has a plurality of function keys 3270, and the touch pad 3210 and the function keys 3270 are, for example, located at a same side of the input device 3200. In the present embodiment, the function keys 3270 may correspond to the left and right keys of a general mouse.
The aforementioned described functions and locations of the control buttons 3220 are not used for limiting the present invention, and the functions of the control buttons 3220 can also be determined by the user himself, and the locations of the control buttons 3220 can also be suitably changed.
As described above, though a pattern of the input device 3200 including the touch pad 3210 and the game joystick is described, music playing or other functions can be extra combined to the input device 3200. Namely, the host 3100 can be remotely controlled by the control buttons 3220 to execute an operation of playing music.
In summary, in the portable computer of the present invention, the input device having a wireless transmission design is integrated with the touch pad and the game control accessories, and the host has a space for containing the input device. Therefore, assembling of the external joystick upon the portable computer of the present invention is unnecessary, which is convenient for utilization. Moreover, the host can be used to directly charge the input device, so that purchasing of the external charger is unnecessary, and meanwhile the usage convenience is improved. In addition, the input device is suitable for being spread out, so as to meet a design of human-factors engineering, by which both of the practicality and the comfortability are satisfied.
