The second rotation arrow 182 indicates that the keyboard tray 130 may rotate in a clockwise direction relative to the main body 110.
Turning now to FIG. 5, a top view of the mobile communications device 100 in the open position with the keyboard tray 130 in the fully rotated position is shown, in accordance with an embodiment of the present invention. The components of the main body 110 and the keyboard tray 130 have been described previously with reference to FIG. 1. Upon rotating the keyboard tray 130 approximately 180° relative to the position of the keyboard tray 130 shown in FIG. 4, a QWERTY keypad 139 is revealed. The standard keypad 138 is now underneath the main body 110 and is not visible. In one embodiment, the keyboard tray 130 may be rotated more than 360 degrees relative to the main body 110.
Turning now to FIG. 6, a top view of the keyboard tray 130 having two keypads is shown, in accordance with an embodiment of the present invention. The keyboard tray 130 is shown apart from the main body 110. As can be seen, the keyboard tray 130 includes a standard keypad 138 and a QWERTY keypad 139. The standard keypad 138 is not a QWERTY type keyboard. The QWERTY keypad 139 is oriented in the opposite direction of the standard keypad 138. Both the standard keypad 138 and the QWERTY keypad 139 are centered on a line running through the center of keyboard tray 130. The keyboard tray 130 rotates around pin 155. The pin 155 is located at the center of the keyboard tray 130. In other embodiments, the pin 155 may be off center. It may be desirable to move the pin 155 off center and closer to an oblong keypad to make room for a longer keypad. Wherein “long” is measured along the radius of the keyboard tray 130. The keyboard tray 130 may include a sensor 167. The sensor 167 may detect the orientation of the keyboard tray 130 and activate the exposed keypad. In addition to activating a keypad to receive or utilize input, other features, such as backlighting keys, may be activated or deactivated based on the position of the keyboard tray 130.
Turning now to FIG. 7, a top view of an alternative keyboard tray 150 having three keypads is shown, in accordance with an embodiment of the present invention. The alternative keyboard tray 150 includes three keypads. The three keypads shown include a QWERTY keypad 151, a standard keypad 152, and a modified QWERTY keypad 154. The three keypads may be activated in turn as the alternative keyboard tray 150 is rotated around pin 155. Again, pin 155 is shown in the center of the alternative keyboard tray 150, but in embodiments of the present invention, the pin 155 may be offset from the center. The alternative keyboard tray 150 includes three sensors: 168, 169, and 170. The three sensors 168, 169, and 170, may activate or deactivate the various keypads as they detect the position of the alternative keyboard tray 150. The sensors 168, 169, and 170 may interact with an indicator on the lower surface of the main body 110 to determine the orientation of the alternative keyboard tray 150. The use of sensors to determine the position of the alternative keyboard tray 150 may become more important when portions of unused keypads are exposed even when they are not in use, which is more likely when more than two keyboards are included in the alternative keyboard tray 150. Using the sensors, the unused keypads may be deactivated so that input accidentally received through the keypads is ignored by the mobile communications device 100.
Turning now to FIG. 8 a partial exploded section view of the main body 110 and the keyboard tray 130 is shown, in accordance with an embodiment of the present invention. The main body 110 defines an elongated channel 162 for receiving the pin 155. The elongated channel 162 is located in the center of the main body 110.
