The operation part 701 is so disposed that a part of the button member 720 is projected from the upper bulge part 31, and the operation part 701 is adapted to lower when an operation surface part 722 of the button member 720 is depressed by a player. A part of the operation part 701 stored in the upper bulge part 31 is masked so as to be invisible from the outside. When a specific state is produced, the operation part 701 is configured to lift to increase a projection amount from the upper bulge part 31, and to make the inside of the operation part 701 visible through the part projecting from the upper bulge part 31 by the lift. The upper bulge part 31 includes a performance device 760 that executes a display performance in an inside area IE of the operation part 701 that becomes visible in increase in the control input.SELECTED DRAWING: Figure 28 |
