Classification: CPC H | IPC H

Claim 4:
5. A non-contact communication system comprising:
the non-contact transmission module according to claim 1; and
a non-contact reception module configured to perform non-contact digital communication with the non-contact transmission module, wherein
the transmitter includes a first port and a second port,
the transmission antenna includes a first portion and a second portion,
the at least one resistor comprises a plurality of the resistors including at least one first resistor and at least one second resistor,
the at least one first resistor is connected in series between the first port of the transmitter and the first portion of the transmission antenna,
the at least one second resistor is connected in series between the second port of the transmitter and the second portion of the transmission antenna,
the digital signal comprises differential signals,
the transmitter is configured to output a positive signal of the differential signals from the first port and output a negative signal of the differential signals from the second port,
the at least one first resistor has such the resistance value that the at least one first resistor entirely blunts the waveform of the positive signal so as to reduce or suppress ringing occurring in the positive signal outputted from the first port, and
the at least one second resistor has such the resistance value that the at least one second resistor entirely blunts the waveform of the negative signal so as to reduce or suppress ringing occurring in the negative signal outputted from the second port,

and wherein the non-contact reception module includes
a reception antenna configured to be electromagnetically or magnetically coupled to the transmission antenna of the non-contact transmission module to induce a reception signal corresponding to at least part of the blunted digital signal, and
a restorer configured to restore the induced reception signal to the digital signal.
