Solid-State Coin Switches
As a coin passes through a slot in the coin switch assembly with any mechanical coin acceptor, it momentarily
interrupts an infrared light beam, causing a solid-state optical detector to send an electric pulse to the CCC. The
duration of this pulse is then checked by the computer to determine its validity. Valid coins will initiate the dispense
cycle. A separate infrared LED and optical sensor and photo-transistor pair is provided for each of the two possible
coin denominations accepted.
Dispenser
The dispenser (see Figure 1-5 ) contains the necessary components to handle the coins. The upper coin chute from
the coin detectors to the bucket, the escrow buckets, solenoid assemblies, and the dispenser chute to the coin cup
are located on this assembly.
The coin detectors, each consisting of an LED and a photo-transistor, detect the coins as they exit from their
respective hoppers and fall into the upper coin chute.
The upper coin chute directs the change to the escrow buckets.
The drive for the hoppers consists of two AC motors, which are also on the dispenser. These motors, as well as
the solenoids which open the bottom door of the escrow buckets, are controlled by signals from the CCC.
You can access the rear of the dispenser assembly by removing the two screws in the upper corners, grasping the
dispenser at the arrow, and tilting the entire assembly forward on its lower pivots.
When you replace the dispenser, be sure that you tighten down the two top screws securely. If these screws are
not tightened down, the entire dispenser assembly may tilt forward when the hoppers are unloaded or removed.
