Abstract
A gaming machine starts a unit game, extracts one set of oscillation pattern data from memory at random when the unit game is started, and performs control to oscillate a playing unit based on the one set of the oscillation pattern data thus extracted.
Claims16
A gaming machine comprising:
- a table on which a die is placed on an upper surface;
- a shaft installed to be upright at a lower surface of the table;
- and
- a control device that controls driving of the shaft in a vertical direction so as to move the table up and down to cause the die to roll on the table, and then cease vertical movement of the table.

A gaming machine comprising:
- a playing unit in which a plurality of dice rolls and comes to rest;
- an oscillation device that oscillates the playing unit;
- memory that stores a plurality of sets of oscillation pattern data corresponding to each of a plurality of oscillation patterns based on which the playing unit is oscillated by the oscillation device;
- and
- a controller that executes processing for:
- (a) starting a unit game;

A gaming machine comprising:
- a table on which a die is placed on an upper surface;
- a shaft installed to be upright at a lower surface of the table;
- a linear actuator that drives the shaft in a vertical direction;
- a base, provided below the table, for supporting the linear actuator;
- and

A gaming machine comprising:
- a table on which a die is placed;
- a shaft installed to be upright to the table in a vertical direction;
- a cylindrical linear actuator that is fixed below the table, has an opening into which the shaft is inserted, and applies a thrust force to drive the shaft in a vertical direction;
- and
- a control device that controls the linear actuator so as to move the table up and down, rolls the dice on the table, and ceases the vertical movement of the table,
- wherein a groove in a vertical direction is formed in any one of the linear actuator and the shaft, a convex portion is formed in the other, and the convex portion is positioned inside the groove when the shaft is inserted into the opening.

A gaming machine comprising:
- a table on which a die is placed;
- a shaft installed upright to the table in a vertical direction;
- a cylindrical linear actuator that is fixed below the table, has an opening into which the shaft is inserted, and applies a thrust force to drive the shaft in a vertical direction;
- and
- a control device that controls the linear actuator so as to move the table up and down, roll the dice on the table, and cease the vertical movement of the table, wherein:
- the shaft includes magnetizing regions that are formed to be aligned in a vertical direction on a surface thereof and are magnetized so that adjacent magnetic poles are different from each other,
- the linear actuator includes coils that are arranged side by side in an vertical direction,
- when the shaft is inserted into the opening, the coils and the magnetizing regions are facing, and a thrust force is generated on the shaft according to attraction and repulsion by magnetic force of the coil and magnetic force of the magnetizing regions, which is generated by applying electrical current to the coils to excite the coils, and
- the control device controls a vertical position of the table.
6 more elements
A gaming machine comprising:
- a playing unit that is substantially horizontal and on which a plurality of dice rolls and comes to rest;
- an oscillation device that causes the playing unit to oscillate substantially in a vertical direction with respect to the playing unit;
- and
- a controller that executes processing of:
- (a) starting a unit game;
- (b) when the unit game is started, performing control that causes the playing unit to oscillate for a predetermined time with a combination of oscillations larger than a predetermined oscillation and oscillations smaller than the predetermined oscillation;
- (c) after elapse of the predetermined time, performing control that causes the playing unit to oscillate with oscillations smaller than the predetermined oscillation;
- and
