In the distribution system 50 described above, it is necessary to bring the contactless data carrier device 30 and the reader / writer 58 closer to each other within the range of the communication distance. Since the communication distance of the non-contact data carrier device 30 is larger than the communication distance of the non-contact data carrier 12 without the auxiliary antenna 34, the communication distance of the cardboard box in which only the non-contact data carrier 12 is attached to the side surface is considered. In comparison, the distance between the belt conveyor 55 and the pillar 59 can be increased, and the cardboard box 51
The degree of freedom of the mounting position can be expanded.

FIG. 14 is an explanatory view illustrating a bag accommodating the non-contact type data carrier device. This bag 6
1 stores a non-contact data carrier device 20. The non-contact data carrier 12 in the non-contact data carrier device 20 is used as a commuter pass.

FIG. 15 is an explanatory diagram illustrating an automatic ticket gate system using a non-contact data carrier device. The automatic ticket gate system 60 has an automatic ticket gate 69 and a non-contact data carrier device 20. The non-contact data carrier device 20 is housed in a bag 61. A reader / writer 68 is provided on a side surface 66 of the automatic ticket gate 69.

The user of the automatic ticket gate system 60 brings the bag 61 closer to the reader / writer 68 of the automatic ticket gate 69 when passing through the ticket gate. The non-contact type data carrier device 20 moves from outside the range of the communication distance with the reader / writer 68 to within the range, and performs wireless communication with the reader / writer 68.
The reader / writer 68 is a non-contact type data carrier device 20.
The automatic ticket gate 69 opens and closes a gate (not shown) based on the information, such as information on the term of validity of the commuter pass, from the non-contact data carrier 12. When the non-contact data carrier device 20 holds a plurality of non-contact data carriers 12, the reader / writer identifies the required non-contact data carrier by the identification code of the data carrier 12 and is valid only from the data carrier. The purpose information such as the term is acquired.

In the above automatic ticket gate system 60, it is necessary to bring the non-contact data carrier device 20 and the reader / writer 68 closer to each other within the range of the communication distance. Since the communication distance of the non-contact data carrier device 20 is larger than the communication distance of the non-contact data carrier 12 without the auxiliary antenna 24, the distance between the non-contact data carrier device 20 and the reader / writer 68 should be increased. Thus, the user can save the trouble of removing the non-contact data carrier 12 from the bag 61.
