Abstract

A communication terminal apparatus having a speech input module arranged movable from a position adjacent to a main shell to a position distanced from the main shell for calling. The communication terminal apparatus includes a transmitter/receiver circuit for modulating and transmitting an output signal from the speech input module, and demodulating and reproducing an input signal, an input control mechanism composed of a plurality of operating keys, a detector mechanism for detecting the position of the speech input module; and a controller device responsive to a detection signal from the detector mechanism for controlling the action of the input control module as well as conducting the transmission and receiving actions of the transmitter/receiver circuit. The controller device is arranged to enable the action of the input control mechanism when a particular one of the operating keys of the input control mechanism is actuated. When the position of the movable speech input module relative to the main shell in a call mode has been detected, its signal is used to control the action of the input control mechanism thus carrying out each control operation correctly without unnecessary …
