1.3.6.1. Tube box
The tube box consists of 5 housings for the tubes, the seat for the elastic forks, the push-button
and the handle for the box opening which are used in case the manual loading of the coins
occurs (see para. 2.1.7.1. “Loading from the tube box”). The information concerning the
configuration of the tube box are reported on chapter 2 at para. “2.1.4. Configuration of the
tube box”.
1.3.6.2. Accumulation tubes
The 5 tubes present in the Coin Mechanism have a particular capacity,
which varies from 97 coins for the 0.05 Euro tube up to 72 coins for the
2.00 Euro tube. The tube configuration in the Coin Mechanism can be
customized according to the operator’s needs (see para.
“Configuration of the tube box”).
The tongues, placed in the lower part of the tube, have the aim to avoid
the spontaneous emission of the coin at the base of the stack, which can
be caused by vibrations or inclinations of the tube box.
When the hook of the cam extracts the coin, the latter is forced to over-
come the resistance of the tongues in order to exit. At the same time the
following coin cannot be extracted because the presence of the elastic
fork, which creates the thickness, prevents that this occurs.

1.3.6.3. Elastic forks
The elastic fork, which is placed in the lower side of the tube box,
guarantees the coin distribution. The thickness of the fork is calibrated
so that the extracting hook of the cam is correctly placed respect to the
coin to be extracted (see para. 1.3.7. “Ejection Group”).

The
Ejection group
consists of 3 motors and 5 cams of different shape, each of them acting on the
single tubes. When the ejection of a coin is requested, the corresponding cam shifts, the hook
passes inside the elastic fork and pushes the coin towards the return channel.
In the ejection group there is the board for controlling the lower photocells which are used for
