Data transfer system
First Claim
1. A data transfer system comprising:
- a master receiver;
at least one slave receiver, said master receiver and said at least one slave receiver respectively having built-in memories storing data therein and being identical in configuration to each other, wherein after said at least one slave receiver in which a data transfer is performed, is disposed in the neighborhood of said master receiver, said master receiver reads the data stored in the built-in memory upon the data transfer, FSK-modulates an oscillation signal of a local oscillator and a standard frequency signal of a standard signal generator using the read data respectively, and radiates the oscillation signal generated from the local oscillator at that time into the air as a leakage radio wave; and
wherein when said at least one slave receiver receives the leakage radio wave radiated into the air, said slave receiver extracts data contained in the received signal and writes the extracted data into the corresponding built-in memory, whereby a data transfer is performed between said master receiver and said slave receiver.

Abstract
The present invention provides a data transfer system that performs a data transfer between a master receiver and at least one slave receiver each of which has a built-in memory storing data therein and is identical in configuration. Upon the data transfer, such at least one slave receiver in which the data transfer is performed, is disposed in the neighborhood of the master receiver. The master receiver FSK-modulates a local oscillation signal of a first local oscillator and a standard frequency signal of a standard signal generator using the data read from the corresponding built-in memory, and radiates the first local oscillation signal generated from the first local oscillator into the air as a leakage radio wave, whereas such at least one slave receiver receives the leakage radio wave therein and writes data acquired from the received signal into the corresponding built-in memory, whereby a data transfer is performed between the master receiver and the slave receiver.
