Apparatus for reading RFID tag information and RFID tag information reading system

An RFID tag information reading system comprising:

• an apparatus for reading RFID tag information having a transmitting portion configured to generate a reading command to acquire information stored in an IC circuit part of a plurality of RFID tag circuit elements including the IC circuit part storing the information and a tag antenna connected to the IC circuit part and transmitting the reading command to said RFID tag circuit elements;
• a feeding device configured to feed said apparatus for reading RFID tag information;
• a movement detecting portion configured to detect a moving state of said apparatus for reading RFID tag information by said feeding device;
• and
• a reading control portion configured to control the number of reading trial times per unit time using said reading command by said transmitting portion according to a detection result of said movement detecting portion,
• said movement detecting portion including a moving amount detecting portion configured to detect a moving amount of said apparatus for reading RFID tag information or a moving direction detecting portion configured to detect a moving direction of said apparatus for reading RFID tag information, wherein
• the RFID tag information reading system further comprises a correlation storage device configured to store and maintain a correlation between said moving amount or said moving direction and said number of reading trial times per unit time corresponding to the moving amount or the moving direction, and wherein
• said reading control portion executes control on the basis of the correlation of said correlation storage device so that said number of reading trial times per unit time is realized corresponding to the moving amount detected by said moving amount detecting portion or the moving direction detected by said moving direction detecting portion.
