Abstract

A driver inserts a key into a key box and it senses the inserted key. By the switch-in signal of a car key sensor(40), the magnetic force of a relay is generated and a 1st switch(SW1) and a 2nd switch(SW2) are turned on. Since the designated electric power is fed by a hand-free(2), a cellular phone(1) is charged and the car is ready for operation. If the driver presses the phone number of the counterpart, the button signal is amplified to the specific level and is fed to a antenna(36) to be transmitted to the telephone exchange office. So, after the counterpart is called up, the communication wave of the counterpart is received by the car antenna through the telephone exchange office.
