发明名称 Electronic dice game
摘要 An electronic dice game apparatus includes an internally powered electronic playing piece containing a random number generator which drives a visual display within the playing piece for displaying one or more numbers or dot patterns corresponding to the dots displayed by one or two dice which have been rolled. A magnetic field sensor within the playing piece is responsive to a magnetic field-producing element within a base forming part of the apparatus in causing a high-frequency oscillator within the playing piece to stop, causing a counter connected to the output of the oscillator to transfer random numbers based upon the accumulated count to the display input drive lines, and causing the display, which is dark in the absence of a magnetic field energizing the playing piece sensor, to display the numbers.
