PCT No. PCT/JP95/01742 Sec. 371 Date Jun. 3, 1996 Sec. 102(e) Date Jun. 3, 1996 PCT Filed Aug. 31, 1995 PCT Pub. No. WO96/07262 PCT Pub. Date Mar. 7, 1996A communication terminal apparatus has a microphone module movable between an on-hook position adjacent to a main shell and a call position distanced from the main shell. The communication terminal apparatus also includes a transmitter/receiver circuit for modulating and transmitting an output signal from the microphone module, and demodulating and reproducing an input signal, a speaker unit for receiving the demodulated input signal and emitting it as an audible sound, a detector mechanism for detecting the position of the microphone module, and a controller device responsive to a detection signal from the detector mechanism for controlling the input and output of the voice signals. The controller device mutes the output signal of the microphone module upon the detector mechanism detecting that the microphone module is located at the on-hook position. Hence, the muting action is activated and deactivated by the movement of the microphone module. When the muting action of the muting means is activated, the transmitter/receiver circuit generates and transmits a hold signal to a calling party at the other end of the line for indicating that the line remains connected.
