ABSTRACT:
A portable radio telephone set comprises a telephone number generating apparatus and a telephone number transmitting apparatus which are preferably contained in a pencil shaped body. The telephone number generating means generates a telephone number signal, for instance, by sensing the motion of a ball provided on a lower end of the body. The ball is moved to draw a telephone number on a surface of an article. The telephone number signal is modulated in the telephone number transmitting apparatus to be transmitted to air by an antenna which is provided on an upper end of the body.
