<P>PROBLEM TO BE SOLVED: To provide a non-contact transmission apparatus in which a passive module is capable of transmitting a data signal captured from the outside to the outside via an active module. <P>SOLUTION: An active module (fixed-side device) includes an electromagnetic transmitting head 4 and an electromagnetic receiving head 5, a power transmitting section is equipped with a transmission means and a control means for controlling an output signal, and a signal receiving section has a reception/control means for receiving a data signal and an information signal, and a sending means for sending the received data signal to an external circuit. A passive module B (mobile-side device) includes a power receiving section and a signal transmitting section, the power receiving section has a receiving means for receiving an electromagnetic wave and a power feeding means for rectifying/smoothing a part of output signals received by the receiving means, forming a power for a power source and feeding the power to the passive module and its optional circuits. Further, the signal transmitting section is equipped with an input means for inputting data signals from the optional circuits and transmitting information signals including the data signals to the signal receiving section. <P>COPYRIGHT: (C)2004,JPO |
