ABSTRACT:
Fingerprint image entry device having no ground electrode provided in a position with which a finger is in a direct contact, wherein accurate fingerprint image can be entered independently of the initial electrostatically charged condition of the finger. The device comprises an electrode which is in the form of mesh or comb for radiating a high frequency wave toward a finger, a plurality of signal sensing electrodes for forming electrostatic capacitance between the electrodes and the finger and a signal switching means for consecutively connecting each of these signal sensing electrodes to a signal sensing circuit.
