| 20090128497 | Portable Electronic Device and its Key structure - A key structure of a portable electronic device is provided. The portable electronic device has a first operation mode and a second operation mode. The key structure comprises a key, a first light source, and a second light source. The first light source emits a first colored light in the first operation mode so that the key can display a first input symbol. The second light source emits a second colored light in the first operation mode so that the key can display a second input symbol. As a result, users who operate portable electronic devices with the aforementioned key structure can easily recognize the different kinds of input symbols corresponding to different input methods in different operation modes. | 05-21-2009 |

| 20100149733 | PORTABLE ELECTRONIC DEVICE AND OPERATION METHOD THEREFOR - A portable electronic device and an operation method therefor are provided. The portable electronic device comprises a first body portion, a second body portion, a sliding module and a rotating module. After the second body portion is slid along the surface of the first portion by the sliding module, the rotating module is promptly triggered to automatically rotate the second body portion to a first angle with respect to the first body portion. The second body portion can be further rotated to a second angle when the second body portion bears a thrust force at the first angle. The portable electronic device can operate in corresponding operation modes according to the angles that the second body portion presents with respect to the first body portion. | 06-17-2010 |
