Fruit Machine Chat

Ive been pulling my fecking hair out for ages trying to work out how the machine removes lost coins.It has a big revolving disc and you flip coins in,if you lose the coin just disappears,no noise or anything.And no wear to playfield,which indicates no sweepers etc.Ive wandered round arcades hoping to see one in bits but never happened.So how are the coins taken away??????????????????????????????????????????????

A metal trap catches the coins. The spinning of the large disc propels the coins to a chute opening, leading to the relevant hopper.

what metal trap.So would it godown a win hole but under that cover it drops down a lose chute.so its divided under the playfeild.Then what it misses the hole,you would get a build up of used coins,can you be more specific
