<P>PROBLEM TO BE SOLVED: To test a mobile station device at a high place without climbing a stand or a ladder. <P>SOLUTION: The installation/housing attitudes in a case body 141A of a communication result display part 145A and an antenna 142A are turned to different angles. The direction of viewing the screen of the communication result display part 145A straight and the directing direction of the antenna 142A are different, and at the time of viewing the screen straight from a horizontal direction, the antenna 142A is directed to an oblique lower front part. An operator just changes the angle of the arm or the neck corresponding to the installation height of the mobile station device and is not required to climb the stand or the ladder. Information is supplied to an external connection device through an external interface 149 and protocol monitoring and communication history management, etc., are made possible. An RF antenna attachment is provided so as to radio connect a VICS beacon transmitter-receiver on a mobile object side in an electromagnetic shielded state to the outside. <P>COPYRIGHT: (C)2003,JPO |
