发明名称 Apparatus for selecting random numbers
摘要 An improved apparatus for the selection of a predetermined quantity of a plurality of random numbers for use in the playing of a lottery game comprising a plurality of numbered balls and a container for the balls. The container is formed of a base, a hollow cover secured to the upper surface of the base and an intermediate member secured between the base and cover at an intermediate location. The intermediate member is formed with a slide extending downwardly from its read portion to its forward portion which includes a trough for supporting the predetermined quantity of balls whereby when inverted, the balls will move to the upper extent of the cover and when reverted the balls will roll down the slide to the lower extent of the cover onto the base with the preselected quantity of balls being randomly received and supported in the trough for reading by the participant of the lottery game. The trough may extend horizontally or generally vertically. The trough may be supported by the cover or the base.
