Currency Cassette
Guides and Latch
1
The currency cassette rests on rails in the side frames of the pick
module. Upper guides on the side frames and a spring loaded catch
hold the cassette firmly in position.
Cassette Identity
Sensors
1
A PCB on the side of the pick module carries four (or eight on the
double pick module) encapsulated reed switches. These switches
are influenced by small permanent magnets housed on the side of
the cassette. The magnets can be moved within the cassette housing,
or left out, so that a given combination of switches is activated. This
creates a binary code (see Chapter 4) which is used to identify the
cassette to the firmware on the control board and thus to the
terminal’s application software which is then able to dispense bills
of a specific denomination.
Pick Module
Keyplate
1
When the cassette is inserted into the dispenser the prongs of the
pick module keyplate enter the holes in its base. The cassette door is
pushed into the cassette base, leaving the front open to permit
access to the currency. On removal of the cassette, the keyplate
draws the cassette door closed and secures the currency within the
cassette.
Pick Action
1
Each pick module carries one pick solenoid, a vacuum system
connected to the vacuum pump in the presenter, and a pick
mechanism. The pick solenoid is energized to cause the vacuum to
be applied to the suction cups. The pick solenoid stays energized
when multiple bills are picked from the same cassette. For each pick
cycle one bill is picked and fed into the transport mechanism.
