The smart card solenoid retracts the smart card rocker downward so
the contacts touch the card. When relaxed, a return spring lifts the
rocker and contacts away from the card.
The duplex clutch controls whether the duplex motor operates the
drive rollers or rotates the whole flipper assembly. The clutch contains
two concentric axes that are free to rotate independently when the
clutch is relaxed. When the clutch is active, a magnetic field pulls the
two axes together and friction forces the two to rotate in unison.
Because the clutch is engaged magnetically, the rotation of either axis
is independent of the body of the clutch.
Operation: The duplex motor rotates the outer axis (large gear), which
is coupled to the two duplex drive rollers. The flipper assembly is
coupled to the inner axis. When the clutch is relaxed, the outer axis
(gear) rotates independently from the flipper assembly, and this
causes the drive rollers to rotate. When the clutch is engaged, the
whole flipper assembly rotates in unison with the large gear, which
keeps the drive rollers from rotating.
The RFID antenna circuit board is a simple loop antenna that
communicates with the supplies ID chip in the ribbon supply spool. The
bi-directional communication method is similar to
Cards (see page 2-33) using load-modulation, although the specific
details may vary.
The duplex interface board contains a step motor driver for the duplex
motor and a 24-volt driver circuit for the clutch. The sensor signals are
passed through directly from the main control board.
There are two types of magnetic stripe daughter boards: 3-track and
single track. The circuit board controls the magnetic stripe head and
provides an interface for the optical encoder. The optical encoder
data is passed back to the main control board without modification.
The smart card daughter board provides a communication interface
between the application computer and the smart card. Most of the
communication aspects and the data transfer are controlled by an
external software application that is transparent to the printer. The
daughter board also provides a connection to control the smart card
solenoid.
