Abstract:
In a configuration for detection of a movement state of a radio tag using a phase difference of a response wave from the radio tag, a phase φ[i] and a measurement time t[i] of a response wave from a radio tag measured are sequentially stored in a memory. A difference from a previous phase and a difference from a previous measurement time with respect to each phase φ[i] stored in the memory are calculated as a phase difference Δφ[i] and a time difference Δt[i]. A phase addition value φsum[i] obtained by cumulatively adding a plurality of the phase differences Δφ[i] is calculated so as to correct a phase difference in which the corresponding time difference Δt[i] among the calculated plurality of the phase differences Δφ[i] exceeds a time threshold tsa [i], whereby the movement state of the radio tag is detected based upon the calculated phase addition value φsum[i].

Claim (Index 7):
The radio tag movement detection device according to  claim 2 , wherein\n the second calculation part can calculate the speed based upon the time difference corresponding to the phase difference in which the time difference becomes equal to or less than the predetermined threshold; and even though the corresponding time difference among the plurality of the phase differences calculated by the first calculation part exceeds the predetermined threshold, a phase difference, in which a sign of the speed calculated from the phase difference which is previously measured and of which the time becomes the closest and a sign of the speed calculated from the phase difference which is measured afterwards and of which the time becomes the closest become different from each other, is defined as the non-correction object.
