Abstract
Abstract A gaming machine has a variable display device for variably displaying symbols for each of a plurality of symbol columns by moving each of the plurality of symbol columns separately in a predetermined direction. The plurality of symbol columns are each formed by a plurality of symbols arranged in the predetermined direction. A drive signal for operating the variable display device is generated when predetermined gaming conditions are satisfied. In response to the drive signal, there is determined a combination of stop symbols to be displayed when the symbol columns are stopped. Positions of the stop symbols are detected separately for the symbol columns, respectively, and position signals indicative of the positions of the stop symbols are generated, respectively. Correction amounts for correcting the positions of the stop symbols are determined based on the position signals. In response to the drive signal, control of the movement and stop of the symbol columns displayed by the display means is carried out, such that the movement of the symbol columns is controlled at the start of movement thereof by the use of the correction amounts until the speed of movement of each of the symbols columns reaches a predetermined uniform speed.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
220 words
A gaming machine comprising: a variable display device for variably displaying symbols for each of a plurality of symbol columns by moving said each of said plurality of symbol columns separately in a predetermined direction, said each of said plurality of symbol columns being formed by a plurality of symbols arranged in said predetermined direction; drive signal-generating means for generating drive signal for operating said variable display device, when predetermined gaming conditions are satisfied; stop symbol-determining means responsive to said drive signal for determining a combination of stop symbols to be displayed when said symbol columns are stopped; position-detecting means for detecting positions of said stop symbols separately for said symbol columns, respectively, and for generating position signals indicative of said positions of said stop symbols, respectively; correction amount-determining means for determining correction amounts for correcting said positions of said stop symbols based on said position signals generated by said position-detecting means; and control means responsive to said drive signal for controlling the movement and stop of said symbol columns displayed by said display means, such that the movement of said symbol columns is controlled at the start of movement thereof by the use of said correction amounts determined by said correction amount-determining means until the speed of movement of each of said symbols columns reaches a predetermined uniform speed.
Claim 2
Dependent Claim
220 words
A gaming machine comprising: a variable display device for variably displaying symbols for each of a plurality of symbol columns by moving said each of said plurality of symbol columns separately in a predetermined direction, said each of said plurality of symbol columns being formed by a plurality of symbols arranged in said predetermined direction; drive signal-generating means for generating drive signal for operating said variable display device, when predetermined gaming conditions are satisfied; stop symbol-determining means responsive to said drive signal for determining a combination of stop symbols to be displayed when said symbol columns are stopped; position-detecting means for detecting positions of said stop symbols separately for said symbol columns, respectively, and for generating position signals indicative of said positions of said stop symbols, respectively; correction amount-determining means for determining correction amounts for correcting said positions of said stop symbols based on said position signals generated by said position-detecting means; and control means responsive to said drive signal for controlling the movement and stop of said symbol columns displayed by said display means, such that the movement of said symbol columns is controlled at the start of movement thereof by the use of said correction amounts determined by said correction amount-determining means until the speed of movement of each of said symbols columns reaches a predetermined uniform speed.
Claim 3
Dependent Claim
73 words
A gaming machine according to claim 1, wherein said control means controls the movement and stop of said symbol columns, such that said stop symbols are lined up when said symbols columns are stopped, by using said correction amounts determined by said correction amount-determining means for correcting said positions of said stop symbols detected by said position-detecting means to thereby cause said symbols to be lined up when said symbols columns are stopped.
Claim 4
Dependent Claim
27 words
A gaming machine according to claim 1, wherein said correction amounts are defined as differences in time points of start of the movement of said symbol columns.
Claim 5
Dependent Claim
27 words
A gaming machine according to claim 2, wherein said correction amounts are defined as differences in time points of start of the movement of said symbol columns.
Claim 6
Dependent Claim
41 words
A gaming machine according to claim 3, wherein said control means starts the movement of said plurality of symbol columns in such an order that said differences in time points for starting the movement of said symbol columns become the minimum.
Claim 7
Dependent Claim
41 words
A gaming machine according to claim 4, wherein said control means starts the movement of said plurality of symbol columns in such an order that said differences in time points for starting the movement of said symbol columns become the minimum.
Claim 8
Dependent Claim
42 words
A gaming machine according to claim 1, wherein said correction amounts are defined as differences in accelerating time periods over which said symbol columns are accelerated until the speed of movement of each of said symbol columns reaches said predetermined uniform speed.
Claim 9
Dependent Claim
42 words
A gaming machine according to claim 2, wherein said correction amounts are defined as differences in accelerating time periods over which said symbol columns are accelerated until the speed of movement of each of said symbol columns reaches said predetermined uniform speed.
Claim 10
Dependent Claim
57 words
A gaming machine according to claim 7, wherein said control means starts the movement of said plurality of symbol columns with reference to an accelerating time period of a first one of said plurality of symbols columns to be started for movement, in such an order that said differences in said accelerating time periods become the minimum.
Claim 11
Dependent Claim
57 words
A gaming machine according to claim 8, wherein said control means starts the movement of said plurality of symbol columns with reference to an accelerating time period of a first one of said plurality of symbols columns to be started for movement, in such an order that said differences in said accelerating time periods become the minimum.
Claim 12
Dependent Claim
15 words
