发明名称 ELECTRICALLY OPERATED RANDOM NUMBER SELECTOR
摘要 An electrically operated random number selector has a main housing with top and bottom walls. A number selection turntable assembly is mounted at the top wall of the housing which contains a power source for rotating the turntable assembly and a power control member at the bottom wall of the housing. When the selector is resting on a support surface, the power control member is held in a power-off position at the bottom wall of the housing, and when the selector is lifted off the support surface, the power control member is automatically movable to a power-on position extending downwardly from the bottom wall of the selector.
