Part Of Dispenser.

We know dispenser is one device on ATM who have function dispense money to the customer on one transaction. Dispenser have some parts module on itself, and how many module or part on dispenser depend or type of cash dispenser. Now we talk for dispenser on generally.
Dispenser consist 3 main module, Feeding Module, Stacking Module and Deliver/presenting module, each module have main function to do work of ATM, beside that! On dispenser have Money Cassette and Reject cassette. For illustration, picture below show module of dispenser old IBM ATM (diebold).




Feeding Module or on picture IBM call it with picker Module. The function of this module is to picking money from cassette and deliver to stacking area. The picking system on this dispenser is friction system which inside of feed module have one big roller for picking money before deliver to stacker unit. And about the cassette, the cassette insert to feed module. Usually on a Atm have 2 or 4 feeding module. Bellow the picture of money cassette inserted to feed module.



If cassette nor inserted to the Feed Module, there no chance to see the money inside if we don’t have a key to open it, but when tha cassette inserted to feed module, there a mechanicly system inside the feed module to open cassette so the money can picking by feed roller. Picture bellow is the Picking Roller inside the feed module.



A mandatory on each dispenser have a double detect sensor, to cheking the money is double or not, other that double detect have function to recognize size of money. If the money size not correct with the setting dispenser. The double detect will be reject the money to reject cassette. On some dispenser like IBM or wincor Nixdorf commonly double detect sensor located on feeding module, so if Dipsenser have 4 feeding module the double detect have 4 module too. But some model of dispenser only have 1 double detect module on stacking area. The cheking money will be do it before money go the stacking area.
Stacking module the function is to collect the money in one bundle before deliver to presenter area. In this area ussualy have one gate to the reject cassette, so if the money double detected by double detect the reject gate will be open and the money not to go to the bundle of money but go the reject cassette.
If in a transaction for example withdrawl 10 notes of money, after stacking module completed with 20 notes, the stacking area will be moving bundle the money to Transport or presenter area to deliver the bundle of money to the customer. On presenter area have sensor on the front, which the function is to detect the customer take money or not, if on 2 or three minutes not take by customer. The dispenser will be moving the bundle money to inside and to the reject cassette.
