Title:
COIN IDENTIFICATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2008/010434
Kind Code:
A1
Abstract:
A coin identification device has a detection section, a first switchover section, a
storage section, and a control section. The detection section has a first sensor including
a pair of coils and an oscillation circuit, receives electric power supply from
the power source, and outputs a detection signal that varies when a coin passes
between the coils. The first switchover section changes magnetic connection
of the coils multiple times between an in-phase connection and a reverse phase
connection while the coin passes the coils. The control section determines the
authenticity of the coin by comparing the detection signal from the detection section
and a reference signal stored in the storage section.
