Both ends of the shaft 162 are connected to the sprocket gear 164. The buckle 丨: The key gear 164 is then coupled to a hinged sprocket gear 166, and these hinged sprocket i gear trains engage the hinges of the lower cover element 142 (not shown in the figure). The action of the spring 160 typically causes the lower cover element 142 to spring to the open position p quickly. However, this fast movement is not welcome and may cause user i to lose control 'and drop the device. The sprocket gear 16 and the relatively sprocket sprocket 16 are used to control the movement of the spring 160, thereby providing a smooth opening operation to shift the lower cover member 142 to the open position. Other offset elements such as a twist bar or even a conductive motor can be used to push the lower cover element 142 to the open position = j

I When a mechanical offset element such as a spring 160 and a torsion bar does not require an external power source, the conductive motor needs a child force from a battery 3 (refer to figure 丨). For this reason, since a conductive motor reduces the operating capacity of the system by discharging power from the battery, a conductive motor is not needed. The system 100 may also use control elements other than the sprocket 164 and the hinge sprocket 166. For example, a counter spring or other braking i · element can also be used to smoothly move the lower cover element 4 2. The system 100 includes elements similar to the automatic shift of the cover element 14 to the open position. The cover element 1 40 can be coupled to the offset system 5 8 or includes an offset system (not shown in the figure). Its function is similar to pushing the upper element to the open position. ^ Other Known techniques can be used to provide smooth operation of the upper cover element 140 and the lower cover element 142. These known offset technique pairs are within the scope of the present invention. Therefore, the present invention is not limited to use 丨.

The chain sprocket wheel 164 and the hinge chain sprocket wheel 166 are contained in the casing 106. When the user presses the actuation button 152, the spring half will cause the sprocket gear 164 to rotate. The sprocket teeth 168 on the sprocket gear 164 are connected to the hinge sprocket teeth 170 on the hinge sprocket teeth 166. When the sprocket gear 64 rotates, the sprocket gear teeth 168 will act on the hinge sprocket gear teeth 708 and rotate the hinge sprocket gear 16 as shown in FIG. 4B. The system 100 can supply the advantages of the latest technology to provide light weight

Type wireless communication device. These upper and lower cover elements 14 and 142 protect the wearer and prevent accidental operation by pressing the keyboard 11 8. The upper and lower cover elements i 4 丨 and 142 can be quickly moved from the flushed position to the open position by pressing a separate button (ie, the actuation button 152). The upper and lower cover elements 14 and u2 — Press, operation can provide user system 100 simple one-handed M. The offset system 158 can automatically open the upper and lower frames 142 and 142 by using a smooth opening motion. In a specific embodiment, the upper and lower cover members 140 and 142 can be closed and bolted, respectively, so that the user can operate with one hand ^ Letong 100 users can slide the upper cover member 14 from the open position Interrogation operation (not shown in the figure) will ... keep the upper unit in the closed position. Then, the user can rotate the lower cover element section U2 from the open position to the closed position. This flash control operation keeps the lower cover element 142 in the closed position. Note that the upper and lower cover elements 14o and

463487 V. Description of invention (11) The order of 1 4 2 is irrelevant. That is, the lower cover member 14 can be closed before the upper cover member 140 is closed, and vice versa. A further improvement of the system 100 is the transparent part 148, which allows the user to view the telephone number of the calling party without having to open the upper cover element 140. This helps to allow the user to decide whether to answer the call without having to press the actuation button 1 5 2. When the lid is opened, some conventional wireless communication devices can automatically answer an incoming call. Since the user does not know who is calling, this operation is not desired until the lid element is opened and the call is answered. However, when the cover element is still closed, the transparent part 1 48 of the system 100 allows the user to view the calling telephone number. The user can view the phone number and decide whether to press the actuation button 152. Therefore, when the upper and lower covers: the components 140 and 142 are moved to the open position without the disadvantages of the traditional wireless communication device, the system 100 can automatically answer the call. As an optional feature, when the system 100 does not receive a call, the display section 12 A (refer to Figure 2B) can display the time and date. Therefore, the system 100 can provide features and advantages not currently used in wireless communication devices. It should be understood that even though various specific embodiments and advantages of the present invention have been published in the previous description, the above disclosure is only illustrative and may be further changed without departing from the scope of the present invention. For example, the system 1 0 0 does not need to include an automatic opening offset system 1 5 8. However, the offset system 158 can include and accept many different forms using well-known techniques. Therefore, the present invention is limited to the patent application scope of the appendix. The scope of its patent application is as follows:
