Folding type portable communication device

1. A folding type portable communication device, comprising:

two communication units connected to each other in a foldable manner and having a folded position and an unfolded position;

a two-level switch for detecting which one of the folded and unfolded position the two communication units have, the two-level switch providing a first level when the two communication units have the folded position and a second level when the two communication units have the unfolded position;

a main controller;

a vibrator;

a sounder;

a mode selector operatively coupled with the two-level switch, the vibrator and the sounder for selectively providing setting for one of a call reception vibration mode and a call reception sound mode in response to the level provided by the two-level switch,

the mode selector including a first circuit for driving the vibrator when energized and a second circuit for driving the sounder when energized;

the mode selector including a controller for energizing the first circuit upon reception of a call, as signaled by said main controller, when the setting for the call reception vibration mode is provided and the second circuit upon reception of a call when the setting for the call reception sound mode is provided.

2. A folding type portable communication device as claimed in claim 1 , wherein the controller energizes the first circuit upon reception of a call when the two-level switch provides the first level indicating that the two communication units have the folded position, and where the controller energizes the second circuit upon reception of a call when the two-level switch provides the second level indicating that the two communication units have the unfolded position.

3. A folding type portable communication device as claimed in claim 1 , wherein the controller energizes the first circuit upon reception of a call when the two-level switch provides the second level indicating that the two communication units have the unfolded position, and where the controller energizes the second circuit upon reception of a call when the two-level switch provides the first level indicating that the two communication units have the folded position.

4. A folding type portable communication device as claimed in claim 1 , wherein the mode selector includes a memory coupled with the controller, and wherein the memory stores the settings for the call reception vibration mode and call reception sound mode.

5. A folding type portable communication device as claimed in claim 1 , wherein the two-level switch includes a magnet mounted within one of the two communication units and a detector mounted within the other communication unit for detecting a magnetic field provided by the magnet.

6. A folding type portable communication device as claimed in claim 5 , wherein the magnet is brought into registry with the detector when the two communication units have the folded position.

7. A method of controlling a selection between a call reception vibration mode and a call reception sound mode of a folding type portable communication device that has two communication units connected to each other in a foldable manner and having a folded position and an unfolded position, said folding type communication device having a main controller and a mode selector including a controller, the method comprising;

detecting which one of the folded and unfolded position the two communication units have;

providing setting for the call reception vibration mode upon detecting the folded position; and

providing setting for the call reception sound mode upon detecting the unfolded position, and

wherein the position of folded or unfolded is determined by a two-level switch connected directly to a controller; and

wherein a main controller, connected to said controller, receives the call reception signal.
