Abstract: A coin dispenser is disclosed to use a dialing rod of a dialing device of a coin dispensing unit to push one side of the peripheral edge of one metal coin so that the other side of the peripheral edge of the metal coin will push two coin-stopping columns of one spring plate of the coin dispensing unit, causing the two coin-stopping columns to slide along the peripheral edge of the metal coin, and thus, when the metal coin crosses two coin-stopping columns, the metal coin is sent out of the coin outlet, achieving the effect of dispensing one metal coin at one time.

Abstract: A coin hopper includes a coin-dispensing unit including a hopper defining a coin outlet, a rotating disk, a power drive, a sensor module and a circuit module for dispensing coins having different thicknesses, and a coin-delivering presser mounted in the hopper and including an elastic member and a float rotatably supported on the elastic member for pressing on one thick coin or thin coin in the rotating disk, enabling the coins to be individually and smoothly delivered to the coin outlet for dispensing and avoiding a coin stuck problem.

Abstract: The invention discloses a coin changing system. The present invention is capable of sensing the coin storing condition of each of the plurality of the accommodating modules arranged in the matrix form of more than 2 rows and 2 columns simultaneously, without limiting the arrangement thereof. Furthermore, the unique design of the guiding component of the present invention is capable of avoiding the coins from getting jammed during the accommodating process thereof. Nevertheless, the present invention requires only one single motor to deal the coins of each of the plurality of the accommodating modules so as to minimize the size of the coin changing system of the present invention. Accordingly, the present invention overcomes the problems presented in the prior art by a relatively simple design.

Abstract: A coin detector having the characteristics of simple structure, low cost and high recognition speed is disclosed to include a housing defining therein a coin passage, and a circuit module, which uses an optical pickup device consisting of an optical module and an analog-to-digital converter to detect the number and pitch of the parallel lines and grooves of the reeded edge of each inserted coin and a microprocessor to determine the authenticity and value of each inserted coin by means of comparing the data of the sensed number of pitch of parallel lines and grooves with a predetermined reference data.

Abstract: A face panel assembly is disclosed having a mounting flange for detachably fastening to a bill/coin acceptor in an automatic vending machine, a slot for the insertion of a bill/coin into the bill/coin acceptor, and a RFID module, which has a sensor for sensing a RFID stored-value card for enabling the RFID module to fetch stored data from the RFID stored-value card and to transmit the fetched data to the automatic vending machine, and a transmission interface (wired or wireless type) for communication between the RFID module and the automatic vending machine.
