Lottery or game of change machine - has wheel with stopping cycle determined by insertion of spring arm in pseudo-random cycle

摘要

A lottery or game of chance system has a large wheel or disc (1) that has a series of symbols or numbers formed in radial segments. Each segment has a projecting stud (3) that is engaged by spring arm (5) as a means of stopping the wheel after being set in motion. The spring arm is coupled to an actuator for movement between the retracted and engaged position. A manual switch (8) can be triggered to initiate a pseudo random cycle for inserting the spring to stop the unit. ADVANTAGE - Improves protection against manipulation of cycle.
