The keyboard (12) is detachably disposed on the body (11). The infrared module (121) and the wireless Bluetooth (RTM) module (122) are disposed on the keyboard (12) and transfer a signal between the body (11) and the keyboard (12). The control circuit (123) detects a distance between the body (11) and the detached keyboard (12). When the distance is less than a predetermined distance, the infrared module (121) is used. When the distance is greater than the predetermined distance, the wireless bluetooth (RTM) module is used (122). The keyboard (12) may also have a rechargeable battery (124) and a connector plug (125). When the keyboard (12) is disposed on the body (11), the connector plug (125) connects with groove (112) and charges the rechargeable battery (124). The body (11) may also include an eject button (111) to detach the keyboard (12) from the body (11). |
