  • Patent number: 8517808
    Abstract: A coin hopper includes a coin pusher consisting of a container, a rotating disc and a power drive for dispensing coins, and a rack that defines therein a coin passage that extends upwardly from the coin pusher and consists of a bottom sloping segment, an intermediate arched segment and a top vertical segment for guiding out coins one by one and has floating rods transversely arranged therein to prohibit dispensed coins from backward displacement and to avoid coin stacking, track parts damage or motor overload.
