The present invention is intended to simplify operation of a folding type portable communication device 1 in making a switch or selection between a call reception vibration mode and a call reception sound mode. The device 1 has two communication units 2 and 3. A two-level switch 4 can detect an unfolded position or a folded position of the communication units 2 and 3, causing a mode selector 5 to select a call reception vibration mode or a call reception sound mode. The mode selector 5 has a first circuit 14 for driving a vibrator 6 and a second circuit 15 for driving a sounder 7. The mode selector 5 has a controller 16. The controller 16 energizes one of the first and second circuits 14 and 15 in response to the selected mode upon reception of a call.
