Our dispenser mechanisms and functions:
1. Uses only 2 levers:
I -Selection of potato flavored crisps
II-Rotating coin slotting device which also dispenses the
crisps container.1. Rotating mechanism coin slotting device (concept of a candy
dispenser)
2. The potato container are stacked vertically into the partition
box and uses gravity to position itself into the plunger zone.
3. The plunger pushes the potato crisps container out of the
partition box and the container falls sliding down the ramp.
4. Only two 50 cent coins are used.
