Abstract
An information communication apparatus includes acoustic and non-acoustic couplers, a switch for selectively connecting an information sending source of the apparatus to the acoustic or non-acoustic couplers, a setting unit for selectively setting items of a communication characteristic of each of the acoustic and non-acoustic couplers, a memorizing circuit for memorizing communication characteristics each having items the values of which are preset by the setting unit, a connection detector for detecting the connection of the acoustic coupler to a communication line, and an information sending controller. The controller connects the sending source to the acoustic or non-acoustic coupler by the switch in response to the acoustic coupler connection or not connection and controls the information sending according to the acoustic coupler or non-acoustic coupler communication characteristic from the memorizing circuit.
