CLOCKING SENSOR DEVICE, CLOCKING MEASURING INSTRUMENT, AND CLOCKING MEASURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a clocking sensor device capable of measuring time without any problem even if quite a large number of competitors, or the like, are participating to a game.;SOLUTION: The clocking sensor device 100 detects that a plurality of moving items pass through a goal 201. The clocking sensor device 100 is held by each of the plurality of moving items. The clocking sensor device 100 includes an ID (identification) tag 40 capable of responding to a predetermined trigger signal and outputting specific different identification numbers; trigger signal transmitting antennas 12, 22 for transmitting the predetermined trigger signal; and an ID receiving antenna 13 responding to the trigger signal and receiving the identification number outputted from the ID tag 40. The ID tag 40 outputs the specific number through a plurality of different frequencies. The ID receiving antenna 13 receives signals of the plurality of frequencies.;COPYRIGHT: (C)2004,JPO
