Coin Comparitor/Optics Theory of operation
« on: June 30, 2021, 03:24:42 PM »
I thought I would check and see if there was a basic explanation of the Coin Comparitor and Optics Unit on the forum. Did not see anything. I searched the web and found a PDF with CC16 Theory of Operation information - a bit much I thought. It was from a universal slot manual.

So I thought I would give it go and see if it might be helpful for new slot machine owners, maybe even some of the others.  :applause:

Comparitor appears to be the correct spelling for Coin Mechanisms Inc. units. Comparator will get you the same and more information. Just FYI.

Coin Comparitor unit - the part that needs the sample coin installed.
With a sample coin installed the unit will allow an object to be inserted/dropped in that is approximately the same diameter of the sample coin. Makes sense, anything larger in diameter should not go in or through and anything smaller in diameter will pass through and be rejected to the coin tray. Because -
the unit has a magnet and electronics to 'see' the object and determine if it matches the sample coin. If it does it will allow the object to go to the Optics Unit below the comparitor unit. If the object does not match the sample coin, it will be rejected by the 'armature' (rake) controlled by the solenoid. The object will be rejected to the coin tray.

If the object is passed OK through the comparitor it will pass through the Optics Unit. This unit checks the object for correct weight by passing through multiple sensors ( 3 usually - A, B, C ). As the sensors are blocked by the passing object, the timing is calculated and a signal is sent to the slot machine telling it a coin has been accepted and to put a credit on the machine. If the timing is incorrect the object would be rejected to the coin tray.

In a nutshell - the coin comparitor checks if the object is close to the diameter of the sample coin and close to the same material (magnet circuit) and the Optics unit checks the object to be sure it is an actual coin, not a slug or other item.

Some helpful information I have learned here on the forum about coin comparitors.

The sensitivity potentiometer can be adjusted to allow the coin comparitor to accept more coins or objects. Good for home use, not so good for casino use. Remember the hopper must dispense the object later so you want the proper coins inserted and accepted. In a slant machine the hopper has the coin tower and will jam easily if a foreign object is allowed to get to the tower - IE a nickel hopper that tries to dispense a penny or a dime or quarter?
The optics unit has a small test switch that is used to send a signal to the machine in test mode (door open) to the machine to verify the wiring, electronics and game are working.

One of the output signals from the Optic unit can be used to put credits on a machine for free play with a modification. I will edit this when I understand what is needed.

No I did not find any information on being able to add credits by modification of the coin comparitor or coin optics. I did try again on an S plus to be sure no signals could be tricked.

This is my understanding of the coin units and anyone can comment or add information.

You can fix almost any electronic device by replacing the aluminum electrolytic capacitors.
