PURPOSE:To attain stably the transmission/reception of data with high accuracy alternately between modules with comparatively a simple circuit constitution by sending a signal with the electromagnetic induction system and receiving signal by the photoelectric conversion system and transmitting power required for the operation of the reception module contactlessly. CONSTITUTION:After an input parallel data SD1 is converted into a serial signal by a P/S conversion circuit 1 in an active module A, the data is an F/S modulation wave by an F/S modulation circuit 3, the frequency is increased by a frequency multiplier circuit 4, power amplication is applied by an RF power amplifier 5 and irradiated into space as an electromagnetic wave form an electromagnetic wave sending head 6. On the other hand, the light flux irradiated from the reception module 8 is received by an optical reception head 7 and converted into an electric signal. Further, the electromagnetic wave for power transmission irradiated from an electromagnetic wave sending head 6 of the active module A is received by an electromagnetic wave reception head 13, a part of the power is rectified into DC by a rectifier and smoothing circuit 14 and fed to each circuit of the reception module 8 as a power supply E1. |
