Abstract:
A tag reader includes: a phase calculation section that sequentially calculates a phase of a reception wave; a phase difference calculation section that calculates a phase difference as a difference of phases calculated at two time points; and a tag angle calculation section that calculates a tag angle between a straight line connecting an antenna and the wireless tag and a line on which the wireless tag is moving. The phase difference calculation section calculates two values of the phase difference. The tag angle calculation section calculates a first tag angle and a second tag angle. The tag reader comprises a tag distance calculation section that calculates an antenna-tag minimum distance as a minimum distance from the line to the antenna.

Claim (Index 2):
The tag reader according to  claim 1 , further comprising:\n a storage portion that stores moving speed of the line beforehand, wherein: the tag angle calculation section calculates the tag travel distance in accordance with a time difference between the two time points and the moving speed of the line stored in the storage portion; and the tag distance calculation section calculates the distance between the position at the tag angle having the first tag angle and the position at the tag angle having the second tag angle, in accordance with the time difference between the time point at the tag angle having the first tag angle and the time point at the tag angle having the second tag angle, and the moving speed of the line stored in the storage portion.
