  • Slot machine arm switch controller
    Patent number: 5472197
    Abstract: In a reel-type slot machine, indicia (reel spin time, reel spin speed, sound, lights, etc.) are varied based on the manner in which the handle is operated. Microswitches are provided to start and stop a timer circuit such that the time required for the handle's rotation can be measured. The game microprocessor looks up the set of values in a ROM table which correspond to the measured timing interval and then implements those values.
