Abstract
A sensitivity disc dispenser including a dispensing structure for housing a plurality of discs containing cartridges and including structure for simultaneously dispensing a disc from each cartridge through each one of a selected number of discharge ports containing a cartridge in a predetermined pattern. The discs are positioned from each cartridge into alignment with the respective discharge port and a tamping mechanism expels the disc through the respective discharge ports into a receiving dish. This tamping mechanism is used to eliminate the time-consuming manual tamping operation required in free fall disc dispensers. It also produces a very consistent spacing between discs. An adjustment device is provided to facilitate vertical positioning of a dispenser with respect to a receiving dish.
