Bill Acceptor
Two drive rollers in the front and two timing belts in the rear of the lower sensor unit
of the Acceptor assure transport of the inserted bill while several red, infrared, and
magnetic sensors scan both faces.
Cash Box
The Cash Box includes drive belts and rollers to assure transport of the bill into the
stacking position. The second motor in the Transport drives them through a gear
train that meshes with another gear train in the Cash Box.
When the bill has moved into position, the pusher is activated via another gear train
and the bill is stacked. The Cash Box has a capacity of approximately 500 bills.
Two plastic levers mounted to the Frame contact the Cash Box and the pusher plate.
These levers mesh with two opto-interrupters at the rear of the Transport, allowing
the microprocessor to detect Cash Box presence and monitor bill-pusher activity.
Bill Entry
Operation commences when a bill of a suitable denomination is inserted into the bill
acceptor. The bill may be inserted face up, either end first. The unit grips the
inserted bill and moves it over the magnetic head and through the optical system.
Analog readings are taken every sixteenth of an inch for the entire length of the bill,
converted to their digital equivalents, and stored in RAM as a profile of the bill. The
stored data are then matched against the profiles stored in program memory.
The bill is evaluated and either accepted or rejected. If the bill is rejected, it is
returned to the player immediately. If the bill is accepted, the machine is notified of
the value of the bill.
If the value of the bill is acceptable, a
