Facsimile apparatus adapted to communicate via an acoustic coupler

An information communication apparatus for communicating information by facsimile, comprising:

• information sending means for sending information;
• acoustic coupler means for acoustically transmitting the information to a communication line through sound according to a predetermined communication characteristic including a plurality of items;
• non-acoustic coupler means for non-acoustically transmitting the information to the communication line according to a predetermined communication characteristic including a plurality of items;
• connection switching means for selectively connecting said information sending means to one of said acoustic coupler means and said non-acoustic coupler means;
• communication characteristic item setting means for selectively setting a plurality of items of the communication characteristic of said acoustic coupler means and a plurality of items of the communication characteristic of said non-acoustic coupler means;
• communication characteristic memorizing means for memorizing a plurality of communication characteristics each having a plurality of items the values of which are preset by said communication characteristic item setting means;
• acoustic coupler connection detecting means for detecting a connection of said acoustic coupler means to the communication line;
• and
• information sending control means for:
• (a) connecting said information sending means to said acoustic coupler means by said connection switching means in response to the detection of the connection of said acoustic coupler means to the communication line by said acoustic coupler connection detecting means, for reading out the communication characteristic of said acoustic coupler means from said communication characteristic memorizing means, and for controlling the sending of the information from said information sending means according to the read out communication characteristic of said acoustic coupler means, and for
• (b) connecting said information sending means to said non-acoustic coupler means by said connection switching means in response to a non-detection of the connection of said acoustic coupler means to the communication line by said acoustic coupler connection detecting means, for reading out the communication characteristic of said non-acoustic coupler means from said communication characteristic memorizing means, and for controlling the sending of the information from said information sending means according to the read out communication characteristic of said non-acoustic coupler means.
