To confirm a measuring state in real time, while measuring surely a moving body moving at high speed.

In the first mode, a CPU 14 supplies all measured data inputted through an A/D converter 11 and CPLD 12 to a Bluetooth radio communication module 15. The Bluetooth radio communication module 15 transmits all the measured data to a communication terminal device 30 in real time. In the second mode, the Bluetooth radio communication module 15 transmits intermittent data acquired by thinning out the measured data to a host computer 40 through the communication terminal device 30. The CPLD 12 writes all the measured data inputted from the A/D converter 11 in a memory 13. After finish of measurement, the data in the memory 13 are read out and transmitted to the host computer 40.
