Abstract: A shuffling machine having an auxiliary card press structure is disclosed. The shuffling machine includes at least one card delivering roller assembly. An outer side of the card delivering roller assembly is pivotally connected with a press arm having a return spring. Another end of the press arm is provided with a card press roller assembly. The card press roller assembly includes at least one magnetic roller. The card delivering roller assembly is provided with at least one magnetic member corresponding to the magnetic roller. When a left accommodating compartment or a right accommodating compartment of the shuffling machine has few playing cards, the magnetic member can attract the magnetic roller to increase the force of the card press roller assembly against the playing cards to increase friction to ensure smooth delivery without idling.

Abstract: A shuffling machine has a central accommodating compartment, a left accommodating compartment, a right accommodating compartment, and a card dispensing space. A translation plate is disposed in the card dispensing space. A driving mechanism is connected to the translation plate. The translation plate is coupled with a card dispensing device for dispensing playing cards. The card dispensing device includes a fixed seat plate and a dispensing block. The fixed seat limits a vertical displacement of the dispensing block within a predetermined distance. Left and right sides of an underside of the dispensing to block have beveled edges. An underside of the fixed seat has an upper magnetic member. A top of the dispensing block has a lower magnetic member. The upper magnetic member and the lower magnetic member are arranged with their like poles to repel each other so that the fixed seat can repel the dispensing block downward.

Abstract: A shuffling machine having a card dispensing structure is provided. The shuffling machine has a central accommodating compartment, a left accommodating compartment, a right accommodating compartment, and a card dispensing space. A translation plate is disposed in the card dispensing space. A driving mechanism is connected to the translation plate. The translation plate is coupled with a card dispensing device configured to dispense the playing cards in the card dispensing space. The card dispensing device includes a fixed seat and a dispensing block. The fixed seat limits a vertical displacement of the dispensing block within a predetermined distance. Left and right sides of an underside of the dispensing block have beveled edges. Thereby, the dispensing block and its beveled edges can prevent the playing card that is mistakenly riffled from being bent and damaged.

Abstract: A lottery ball machine includes a box body, having tubes at a top thereof; a ball guide seat, having upper through holes and ball return holes at a top thereof and ball passages therein, upper ends of the ball passages being connected to the upper through holes, lower ends of the ball passages being communicated with the tubes; a ball control seat disposed above the ball guide seat, including an upper seat plate assembly having ball outlets, a lower seat plate having limit holes, receiving tubes connected to the limit holes, and displacement plates disposed at the bottom of the lower seat plate; ball tracks, upper ends of the ball tracks being disposed under the ball return holes, lower ends of the ball tracks corresponding to the box body, a gate assembly being provided between each ball track and the box body; and blowers, located under the box body.

Abstract: A duplicate playing card output and recycling device is provided for an electronic game system to print, output, and recycle playing cards. The device is connected to the game system to print a duplicate playing card having the same suit and numeral as that dealt by the electronic game system. The device includes a printing device and a recycling device. The printing device is able to print the duplicate playing card to the player. The recycling device is able to recycle the duplicate playing card. The device enhances the fun and excitement of the game, and the duplicate playing card won't be arbitrarily disposed.

Abstract: A robotic arm suction cup capable of eliminating negative pressure is provided. A robotic arm is provided with a first suction cup and a second suction cup of unequal length. Each of the first and second suction cups is connected with a Y-shaped tube. An end of the Y-shaped tube is connected with a communication tube. The communication tube is connected with a vacuum pump. Another end of the Y-shaped tube is connected with a pressure detection tube. A distal end of the pressure detection tube is connected with a pressure detector. The first and second suction cups are not coplanar, and can effectively eliminate the negative pressure between the first and second suction cups and a playing card rapidly, so that the playing card can be separated from the first and second suction cups easily for the game to go on smoothly.

Abstract: An earthquake warning disaster prevention and safety report-back system comprises a servo host group constituted by servo hosts and a mobile communication device. When an earthquake is formed, the servo hosts that are distributed by location in Taiwan are utilized for simultaneously receiving earthquake real-time data information transmitted from the Central Weather Bureau, using the servo hosts to evaluate a physical location of a client, and using one servo host that is located at an optimum (nearest) site to distributively transmit earthquake real-time data information to the mobile communication device of the client. When the mobile communication device receives the earthquake information, the mobile communication device transmits a warning message to the client and provides earthquake magnitude and an earthquake wave arrival time of the physical location as instructions to perform prevention and escape measures, thereby seizing the recuse golden hour.
