Abstract
A reading apparatus includes a mechanism to move an antenna between first and second positions, and a controller configured to: (a) control the antenna to transmit radio waves to wireless tags each attached to an object when the antenna is between the first and second positions; acquire, from response waves, information registered in each tag and indicating attributes of the object and the tag, and signal values of the response waves; and calculate an estimated position of each tag and a reliability level thereof based on the values. When the level of the position of a tag is less than a threshold or when the information of a tag indicates an attribute that can affect radio communications, the controller performs step (a) again, acquires signal values of response waves received from the tag, and calculates an estimated position of the tag and a reliability level thereof based on the values.
