The rf leader unit which features

摘要

(57) Abstract The compact rf leader device (10) it is unified to single compact package structure. With one example, the head which revolution possibly it can adjust (18), the read/write electronic circuit (60) with the joint controller (68) the compact leader itself part which is stored (12) it is mounted on. The antenna (54) it stores the head which revolution possibly it can adjust, in order this antenna to direct to the direction where large number differs the compact leader itself part of the rf leader (12) without moving, it is adaptation. Furthermore, with one example, rf leader unit (10) the reader one computer part (12) the change power source which is laid out inside (62) it has. Change power source (62) the read/write electronic circuit (60) with the joint controller (62) we are jointed electrically, at the same time transmission frequency of the antenna synchronization do and prevent interference.
