Full detection.
Full detection, as with the empty detection, is carried out by a photocell
(photodiode and phototransistor) that is located in the holes at the top of the coin
bay.
The photodiode emits a beam of light that is detected by the phototransistor when
the coin level is lower than the photocells. When the coin level is higher lower than
the height established for the photocells, the control board detects this and advises
the machine.
The application of this system is possible in all the hopper models.

BLADE.
The function of this element is to slice between the coin and the disk making the
coin leave the hopper. The
hoppers
can have two types of blade:
Long blade
: for disks of 7
and 8 ridges.
Short blade
: for disks of 12
ridges.
Figure 9. Types of blade
Both models have a metallic reinforcement which is held on the blade with a screw.
