DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to FIG. 5, a schematic perspective view of a computer peripheral device according to a preferred embodiment of the present invention is illustrated. An exemplary computer peripheral device is a cursor control device 5. The cursor control device 5 as shown in FIG. 5 comprises a first housing 51, a second housing 5, a connecting member 53 and a judging circuit 54. The cursor control device 5 further includes an optical sensor 60 inside the first housing 51 and triggered to generate a cursor control signal. A receptacle (not shown) is defined within the second housing 52 for accommodating at least a battery (not shown) therein. The connecting member 53 is made of a conducting material. Via the connecting member 53, the first housing 51 is coupled with the second housing 52. The connecting member 33 has a rotating shaft 530. By means of the rotating shaft 530, the second housing 52 is rotatable relative to the first housing 51. Likewise, since the second housing 52 is rotatable relative to the first housing 51, the cursor control device 5 may be switched between a cambered configuration (as shown in FIG. 4(c)) and a flat configuration (as shown in FIG. 4(a)) according to the user's requirement.

Moreover, the judging circuit 54 is arranged inside the first housing 51, and includes a first conducting contact 541 and a second conducting contact 542. Selectively, the first conducting contact 541 and the second conducting contact 542 are electrically connected to the connecting member 53 through a first flexible metallic plate 543 and a second flexible metallic plate 544, respectively.

A major feature of the present invention will be illustrated in more details as follows. In a case that the second housing 52 is rotated relative to the first housing 51 with rotation of the rotating shaft 530 such that the cursor control device 5 has a cambered configuration, the first conducting contact 541 is electrically connected with the second conducting contact 542 through the connecting member 53. Under this circumstance, the judging circuit 54 will activate the function of controlling cursor movement. In another case that the second housing 52 is rotated relative to the first housing 51 with rotation of the rotating shaft 530 such that the cursor control device 5 has a flat configuration, the connecting member 53 is not electrically interconnected between the first conducting contact 541 and the second conducting contact 542. Under this circumstance, the judging circuit 54 will activate the function as a remote controller. As a consequence, the cursor control device 5 can be operated in different function modes by switching the configurations thereof. Moreover, when the cursor control device 5 is operated in a function mode, the other function mode is disabled, and thus the power consumption of the battery is saved.

Referring to FIG. 6, a schematic perspective view of the connecting member 53 used in the cursor control device 5 of the present invention is illustrated. In addition to the rotating shaft 530, the connecting member 53 further includes a first connecting plate 531 and a second connecting plate 532. The first connecting plate 531 and the second connecting plate 532 are fixed onto the first housing 51 and the second housing 52, respectively. The first connecting plate 531 is coupled to the second connecting plate 532 via the rotating shaft 530, such that the second connecting plate 532 is rotatable relative to the first connecting plate 531 and the second housing 52 is rotatable relative to the first housing 51 via the rotating shaft 530. As shown in FIG. 6, a rotating surface 5302 of the rotating shaft 530 further includes a notch 5301. When the second housing 52 is rotatable relative to the first housing 51, the notch 5301 is also rotated to different positions. Depending on the positions of the notch 5301, the first conducting contact 541 is electrically connected with the second conducting contact 542 through the connecting member 53 or electrically disconnected from the second conducting contact 542. The related principles will be illustrated in more details as follows.

Please refer to FIGS. 7(a) and 7(b), which are partially schematic perspective views illustrating electrical connection and electrical disconnection between the first conducting contact 541 and the second conducting contact 542. As shown in FIG. 7(a), in the case that the second housing 52 is rotated relative to the first housing 51 such that the cursor control device 5 has a cambered configuration, the notch 3201 of the rotating surface 5302 of the rotating shaft 530 is rotated to a first position, which is distant from the second flexible metallic plate 544. Under this circumstance, the first flexible metallic plate 543 is in contact with the first connecting plate 531 of the connecting member 53, and the second flexible metallic plate 544 is in contact with the rotating surface 5302 of the rotating shaft 530. Consequently, the first conducting contact 541 is electrically connected to the second conducting contact 542 through the connecting member 53, so that the judging circuit 54 will activate the function of controlling cursor movement. As shown in FIG. 7(b), in another case that the second housing 52 is rotated relative to the first housing 51 such that the cursor control device 5 has a flat configuration, the notch 3201 of the rotating surface 5302 of the rotating shaft 530 is rotated to a second position, which is next to the second flexible metallic plate 544. When the notch 3201 is rotated to the second position, the second flexible metallic plate 544 is received in the notch 3201 but separated from the rotating surface 5302 of the rotating shaft 530. Under this circumstance, the connecting member 53 is not electrically interconnected between the first conducting contact 541 and the second conducting contact 542, so that the judging circuit 54 will activate the function as a remote controller. Since the power supplied to the optical sensor for detecting of the cursor control signal is interrupted, the function of controlling cursor movement is disabled and the power consumption of the battery is saved.

In the above embodiments, when the cursor control device 5 is adjusted to have the cambered configuration and the first conducting contact 541 is electrically connected to the second conducting contact 542, the cursor control device 5 is operated in a first mode to control cursor movement. Whereas, when the cursor control device 5 is adjusted to have the flat configuration and the connection between the first conducting contact 541 and the second conducting contact 542 is interrupted to save power, the cursor control device 5 is operated in a second mode and acted as a remote controller. It is noted that, however, those skilled in the art will readily observe that numerous modifications and alterations may be made while retaining the teachings of the invention. For example, when the cursor control device 5 is adjusted to have cambered configuration and the connection between the first conducting contact 541 and the second conducting contact 542 is interrupted, the cursor control device 5 can be operated in a first mode to control cursor movement; and when the cursor control device 5 is adjusted to have the flat configuration and the connection between the first conducting contact 541 and the first conducting contact 541 is electrically connected to the second conducting contact 542, the cursor control device 5 is operated in a second mode to be acted as a remote controller and the power supplied to the optical sensor is interrupted for reducing power consumption. Accordingly, the above disclosure should be limited only by the bounds of the following claims.

From the above description, the cursor control device of the present invention can be operated in different function modes by switching the configurations thereof. By rotating the second housing relative to the first housing, the cursor control device of the present invention can be switched between a cambered configuration like a mouse and a flat configuration like a remote controller. Moreover, the judging circuit of the cursor control device will activate either the function of controlling cursor movement or the function as a remote controller according to the configuration of the cursor control device. When the cursor control device is used the remote controller, the power supplied to the optical sensor is interrupted, so that the power consumption is reduced. More especially, by adjusting the notch of the rotating surface between a first position and a second position with rotation of the rotating shaft, the first conducting contact is electrically connected to or separated from the second conducting contact. Therefore, the drawbacks occurred in the prior art are overcome.

While the invention has been described in terms of what is presently considered to be the most practical and preferred embodiments, it is to be understood that the invention needs not be limited to the disclosed embodiment. On the contrary, it is intended to cover various modifications and similar arrangements included within the spirit and scope of the appended claims which are to be accorded with the broadest interpretation so as to encompass all such modifications and similar structures.
