Abstract: A game machine includes: an entertainment button that can move up and down from a normal operation position to a protruding position; an assigned object determining part that determines an assigned object; a prize determining part that determines a prize to be given to a player, when the assigned object determining part determines an assigned object; a prize display part that displays a prize symbol corresponding to the prize determined by the prize determining part; a movement determining part that determines whether or not to move the entertainment button from the normal operation position to the protruding position; a drive control part to move the entertainment button from the normal operation position to the protruding position, when the movement determining part determines to move the entertainment button from the normal operation position to the protruding position; and a push operation detecting part that detects the entertainment button being pushed down.

Abstract: A game machine includes: an entertainment button that can move up and down from a normal operation position to a protruding position; a display part that displays characters related to a content of a game; a character determining part configured to determine a character to be displayed on the display; a stopper plate that holds the entertainment button in the protruding position; and a protruding position detecting part that detects the entertainment button being held in the protruding position by the stopper plate. When the protruding position detecting part detects the entertainment button not being held in the protruding position after having detected the entertainment button being held in the protruding position, the character detecting part recognizes that the entertainment button held in the protruding position is pushed down, and therefore determines a predetermined character. When the character determining part determines the character, the display part displays the determined character.

Abstract: An entertainment button device includes an entertainment button and a button-up-and-down mechanism configured to move the entertainment button up and down from a normal operation position to a protruding position in which the entertainment button protrudes upward from the normal operation position, and including: a shaft member extending in a moving direction of the entertainment button; a rotating mechanism that rotates the shaft member; an engagement part that moves up and down together with the entertainment button; and a spiral guide part formed in a spiral manner on an outer periphery of the shaft member, the engagement part engaging with the spiral guide part. When the rotating mechanism rotates the shaft member in a specific direction, the entertainment button moves to the protruding position, and when the rotating mechanism rotates the shaft member in an opposite direction from the specific direction, the entertainment button moves to the normal operation position.
