PURPOSE:To facilitate one-hand operation by using an adaptor for inverting a receiver microphone face to place a 2nd receiver and microphone onto a rear side of a handset and allowing the operator to use only his one hand for talking by means of the 2nd receiver or the like. CONSTITUTION:When a handset 1 is pressed onto a part of almost channel shape of an adaptor 11, claws 14, 15 are fitted to recessed parts 12, 13, and the adaptor 11 holds the handset 1. When the adaptor 11 is put on a cradle 2, set claws 23, 24 invade recessed parts 21, 22 of the adaptor 11 to set the cradle 2. In the case of making dialing, the operator uses his one hand to operate a key operation section 4. When the dialing is finished, the operator uses the same one hand to grip a side A of the handset 1 and to remove the handset 1 and the adaptor 11 from the cradle 2, and the talking is attained by allowing the operator to bring the 2nd receiver 19 and the microphone 20 placed at the lower side of the adaptor 11 in this state, that is, the side opposite to the said side to his ear and his mouse respectively. |
