PROBLEM TO BE SOLVED: To prevent information received by a reader-writer from being erroneously judged at the time of transmitting information to the reader-writer in non-contact state by providing a time lag between the mark of a high-order signal level and the mark of a low-order signal level arranged adjacently to each other in a slot. SOLUTION: The mark of the high-order signal level (a mark in the state of a value '1') and the mark of the low-order signal level (a mark in the state of a value '0') are included the slot and the time lag is provided between the mark of the high-order signal level and the mark of the low-order signal level arranged adjacently to each other. Therefore, even in the case when distortion is caused in the waveform of the mark of the high-order signal level in the slot transmitted from a mobile information communication object, the influence of the distortion to the position of the mark of the adjacent low-order level is reduced. Thereby, it is ensured to obtain correct information based on a received signal. |
