2. Description of the Related Art In recent years, in order to improve the convenience of users (passengers), a commuter pass is a non-contact ticket composed of an IC card having a wireless communication function, and the non-contact ticket is held over an antenna of an automatic ticket gate. There has been proposed a non-contact automatic ticket gate capable of performing entry processing or entry processing (entrance / exit processing). When the commuter pass is such a non-contact pass, the user can enter and exit from the commuter pass without having to put in and take out the commuter pass, like a commuter pass made up of conventional magnetic tickets.

[0003] Further, since the contactless ticket is made of an IC card, it has a much larger storage capacity than a conventional magnetic ticket. It has been considered to provide a so-called electronic wallet function. Then, it is considered that it becomes possible to pay for a product purchased at a store at a station using the electronic wallet using a non-contact payment machine provided at the store or the like.

When entering or exiting or making a payment using a contactless ticket, a command signal is transmitted from the contactless ticket processing device (reader / writer) such as a contactless automatic ticket gate to the contactless ticket, and the command signal is transmitted. , Predetermined card data such as commuter pass data and amount data stored in the contactless ticket is sent to the contactless ticket processing device.
Therefore, the contactless ticket processing device can perform predetermined arithmetic processing such as entrance / exit processing and settlement processing based on predetermined card data received from the contactless ticket.

However, in the conventional contactless ticket processing apparatus, the signal state received from the contactless ticket is reversed, and the signal from the contactless ticket cannot be correctly received. There has been an inconvenience that predetermined processing such as participation cannot be performed.

For example, as shown in FIG. 4, when a non-contact ticket A is stored in a card holder (commuter pass holder) C, coins M are stored together in the card holder C, or When another contactless ticket (not shown) is stored in a stacked state, the surrounding radio wave environment changes, and in the state of the change, a high level (High Field) of a signal reaching the contactless ticket processing device is stored. And a low level (Low Field) may be reversed. In particular, when the communication method is the NRZ method or the Manchester method, the data "1" and "0" are reversed to "0" and "1", and the response in the contactless ticket processing device (reader / writer) is returned. Processing becomes impossible.
