Abstract: A cash receiver installed in an amusement machine for controlling the operation of the machine, including a face panel that has a coin slot, a coin-return slot and a vertical bill slot, a coin receiver unit that is affixed to the rear side of the face panel and has a coin entrance passage connected to the coin slot and a coin-return passage connected to the coin-return slot, and a bill receiver unit that is affixed to the rear side of the face panel and abutted against one side of the coin receiver unit and has a bill passage connected to the vertical bill slot. The client can insert a coin or a bill into the cash receiver to play the amusement machine.

Abstract: The invention discloses a card discriminating system used for identifying whether a card is authentic or not. The card has a surface, and N sensing marks are formed on the surface of the card. The card discriminating system includes a position-based pulse generation module, at least one sensor, and a micro-controller unit. The micro-controller unit is respectively coupled with the position-based pulse generating module and each of the sensors. When the card actuates and passes through the position-based pulse generating module, the position-based pulse generating module will generate a reference position-based pulse. When one of the N sensing marks of the card passes through one of the sensors, the sensor will generate a corresponding sensing position-based pulse. The micro-controller unit is used for comparing the sensing position-based pulse with the reference position-based pulse, so as to identify whether the card is authentic or not.

Abstract: A multiple card reading modules apparatus includes a first card reading module and a second card reading module. The first card reading module includes a card receiving structure. The first card reading module reads a first card signal based on a control signal through the card receiving structure. The second card reading module is combined with the first card reading module through a combination device for sharing the card receiving structure to read a second card signal and generate the control signal based on the content of the second card signal.

Abstract: A roller activation apparatus includes a switch, a roller, a light generator and a light receiver. The roller contacts the switch. A wheel of the roller has at least an opening. A wheel surface of the roller is touched to activate the switch by inputting a card. The roller rotates based on a movement of the card. The light generator is disposed at a side of the roller and is for generating a light beam. The light receiver is disposed at another side of the roller and is for receiving the light beam through the opening of the wheel so as to generate a pulse signal. The pulse signal corresponds to the movement of the card.

Abstract: A casing structure for a card reader is disclosed. The casing structure is composed of at least an upper casing structure and a lower casing structure. In addition, an elastic hook and a hook notch are disposed on at least a side of the upper casing structure. A protruding cylinder and a support cylinder are disposed on a side of the lower casing structure. After the hook notch covering the support cylinder, the elastic hook can be displaced flexibly for hooking the protruding cylinder. Hence the upper casing structure then covers the lower casing structure tightly.
