Disclosed is an antenna unit for a bookshelf. The antenna unit for a bookshelf according to an embodiment of the present invention comprises: an antenna body which is located between a plurality of wireless connection targets to which wireless connection identifiers are attached, detects a radio wave generated from the wireless connection target, and receives information on the wireless connection target placed on a shelf of a current storage closet; a guide rail which is provided on the storage closet such that the antenna body is moved along a length direction of an upper surface of the shelf; a sliding unit which is provided at a bottom of the antenna body and partially inserted into the guide rail to be moved along the length direction of the antenna body; and a position fixing unit which is provided on the antenna body to selectively perform a position fixing process with respect to the antenna body which is moved to a specific position along the sliding unit. The position fixing unit includes: press portions which are inserted into an inner portion of the antenna body to face each other and partially protrude toward an outer portion of the antenna body such that the press portions are pushed by a user; an elastic portion whose both ends are elastically supported between the press portions to elastically support the press portions toward the outer portion of the antenna body all the time; and a holding slice which is extended from the press portion such that an end of the holding slice is extended toward a position fixing groove, and moved toward the position fixing groove according to a push state of the press portions to maintain a locking state or an unlocking state. According to the present invention, the wireless connection target, to which a radio frequency identification (RFID) tag is attached, is easily detected such that accurate data on plural wireless connection targets can be obtained using a small number of persons. |
