PROBLEM TO BE SOLVED: To easily receive/transmit data without respect to the direction of the side face of a conveying case by arranging a spirally swirling antennas, which are arranged in series in the diagonal two corners in a box-shaped conveying case main body via a connecting line, and a data carrier connected to the antenna magnetically. ;SOLUTION: A conveying case 20 is constructed of a conveying case main body 21, spirally swirling antennas 27a, 27b arranged in series in the corner parts of diagonal side faces 23a, 23c via a connection line 29, and a data carrier 13, which is applied above or near one of the antennas 27a, 27b and magnetically connected to the antennas 27a, 27b. When the conveying case 20 is conveyed by means of a conveyor 1 to a transmitting-receiving means 7, the data carrier 13 is brought face to face with the transmitting-receiving means 7, and a signal transmitted from the transmitting-receiving means 7 is transmitted to the data carrier 13 via the antenna 27a. If the direction of the conveying case 20 is reversed and the other antenna 27b faces the transmittingreceiving means 7, data is transmitted and received between the transmitting-receiving means 7 and the data carrier 13 via the connection line 29.;COPYRIGHT: (C)1997,JPO
