触式識別装置。 A unit that generates alternating current in an LC parallel resonant circuit using a changing magnetic field, obtains a constant voltage direct current power source with a rectifier and regulator, reads out a predetermined code number set in a ROM chip, and transmits it on FM radio waves. , a magnetic field is formed in a resonant state by an LC series resonant circuit in response to supply of an alternating current having a frequency that forms a resonant state, and an FM receiving means receives and decodes FM radio waves transmitted from the unit. and a control means that inputs the information of the decoded signal from the sensor, collates it with the information in the master file, and outputs the collation result. A contactless identification device featuring:
