Abstract (en)
A device is provided for automatically discriminating a spot number of an upward face of a die (1) with six faces. The device includes a signal transmitter (2) embedded in the dice (1) and a receiver device (3). The receiver device (3) includes a set of receiver and an operation computer. The signal transmitter (2) includes a substrate (21) embedded in the die (1) with respect to one of the six faces of the die (1). A sensor chip (26) is mounted on the substrate (21). The substrate (21) further includes four corner areas each having a conductive element (211,212,213,214) mounted thereon. Each mercury switch (22,23,24,25) extends upward and outward from and electrically connects to each conductive element in a manner that each mercury switch is at an angle of 15 DEG SIMILAR 75 DEG with the substrate (21). Each mercury switch (22,23,24,25) contains conductive mercury therein. The mercury in each mercury switch flows under gravity so as to be in one of a conductive status and a non-conductive status with respect to an associated conductive element, thereby generating a signal representing the status of the mercury switch. The operation computer discriminates the spot number of the upward face of the die (1) according to the signals representing the status of the mercury switches (22,23,24,25). <IMAGE>
