Abstract: To guide other products related to a product which is taken out in hand by a customer. The present product display rack system carries out a first step for detecting an RFID number of a product taken by a customer from desired display racks 11 to 14 based upon the detection result of the RFID reader; a second step for acquiring RFID numbers of related products having related product types and functional types relative to the product type of the RFID number from the product related information data base 260 by using the detected RFID number as a key; a third step for acquiring the product display coordinates of the product type from the product coordinate data base 250 by using the acquired RFID number of the related product as a key; and a fourth step for lighting or flickering the lamp of the lamp guiding units 30 to 33 at a position close to the acquired product display coordinates.

Abstract: To provide a classification device in which product fine powder little in mixture ratio of coarse particles can be obtained. A classification device characterized in that a setting pitch P between stationary fins 13 and a width L of each stationary fin 13 are combined so that a value of P/L is in a range between 0.042×(??50)+0.64 and 0.019×(??50)+0.22 in 50°???70° when ? is an inclination angle of each stationary fin 13, P is the setting pitch, and L is the width in a direction of circulation of particles.

Abstract: A system with an intelligent shelf (100) has product display shelves (110 to 130) displaying products having RFID tags R. The system includes antennas (112a to 112c) each having unique antenna numbers and detecting a tag serial number from an RFID tag on a product, human body sensors S disposed on each end of the product display shelf 120, a tag-product ID registration table storing the tag serial numbers of the RFID tags and the product IDs of the products and a control computer (200) detecting that a particular product is picked up from and/or returned to a particular product display shelf by combining the input tag serial number and the antenna number of the antenna detecting the tag serial number and analyzing which direction the detected human body has moved based on the difference of the detection times of the human body sensors.
