Coin Chute Assembly
6.2 MC-62 Coin Comparator

6.2.1 Basic Operation

The operation of the coin chute assembly is shown in Figure 6-1.
Once in the comparator, the coin is assessed for its diameter, mass, and magnetic
signature.
Rejected Coins
If the comparator rejects the inserted coin, it is sent to the chip tray via the reject
chute.
Alarm
If the comparator detects a slow moving coin, or a coin travelling in the wrong
direction:
the machine displays a fault message
•
an alarm is sounded
•
the machine is locks up.
•
Accepted Coins
If the comparator accepts the inserted coin, it is directed to the coin accept chute.
If the coin passes normally, a credit signal is sent to the Main Board and the
electronic and electromechanical credit meters are incremented. The coin diverter
solenoid directs the accepted coins to the hopper. If the hopper is full, the coin
diverter solenoid redirects the accepted coins to the cash box via the cash box feed
chute. A photo-optic sensor is used to monitor the position of the coin diverter.
