The invention provides a coin-type bulk media conveying mechanism which rapidly and stably conveys a great amount of coins by damaging the dynamic balance of a coin-type bulk media in a conveying process. The coin-type bulk media conveying mechanism is used for containing and conveying the coin-type bulk media to an appointed outlet and comprises a synchronous belt, a pair of synchronous belt pulleys and at least two oppositely arranged supporting walls, wherein the synchronous belt is sleeved on the pair of synchronous belt pulleys to form a conveying surface, and at least one balance damaging element is arranged above the conveying surface, used for ensuring that the coin-type bulk media falling on the conveying surface is conveyed in a mode of the lowest center of gravity and comprisesone or more combinations of soft thin plates, or deadweight movable baffles or bridge-type stop blocks. The invention realizes the miniaturization of a coin-type bulk media allocation device and a self-service terminal with the coin-type bulk media allocation function.
