Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
121 words
A slot machine device comprising changeable display means, a pseudo random number generator, a microprocessor connected between the number generator and display means for accessing former and controlling the latter to present an apparently randomly selected character, said display means comprising a matrix of activatable display elements arranged in rows and columns, character generator means connected between said microprocessor and display means and controlling activation of said display elements to present a character and to change the activated display elements to present the appearance of a moving character, and a variable speed timer connected to said microprocessor to modify the transfer rate of randomly selected character input signals from the microprocessor to said display element to simulate a decelerating mechanical wheel.
Claim 2
Dependent Claim
121 words
A slot machine device comprising changeable display means, a pseudo random number generator, a microprocessor connected between the number generator and display means for accessing former and controlling the latter to present an apparently randomly selected character, said display means comprising a matrix of activatable display elements arranged in rows and columns, character generator means connected between said microprocessor and display means and controlling activation of said display elements to present a character and to change the activated display elements to present the appearance of a moving character, and a variable speed timer connected to said microprocessor to modify the transfer rate of randomly selected character input signals from the microprocessor to said display element to simulate a decelerating mechanical wheel.
Claim 3
Dependent Claim
89 words
A slot machine device according to claim 1, said microprocessor comprising a central processor unit connected to said display means, a read only memory connected to said central processor unit for imparting permanently stored information to the central processor unit, and a random access member connected to said central processor unit for imparting temporarily stored information to the central processor unit, for operating said coin dispenser control means responsive to the interaction of signals from said number generator on information stored in said read only and random access memories.
Claim 4
Dependent Claim
52 words
A slot machine device according to claim 2, in combination with timer means connected to said central processor unit for controlling concurrent and sequential operation of said memories and central processor unit, and resettable counters and delay control registers connected to said central processor unit for counting and delaying the various operations.
Claim 5
Dependent Claim
19 words
A slot machine device according to claim 3, in combination with indicator means for indicating various slot machine operations.
