The scheduled departure data and time is automatically operated by a control part. When the set alarm time comes, a power source circuit is turned on by a timer signal (YES in step S7) by operation of a timer part, and a portable phone carried by a driver, etc., is called by a communicating part and connected to a telephone line (step S8). A message for alarming the driver to depart is output via the communicating part and the portable phone (step S9).
