Patent ID: 8795081

Claim:
A game machine comprising: an entertainment button configured to be able to move up and down from a normal operation position to a protruding position in which the entertainment button protrudes upward from the normal operation position; a display part configured to display 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 configured to hold the entertainment button in the protruding position; a protruding position detecting part configured to detect the entertainment button being held in the protruding position by the stopper plate; and a push operation detector which uses hardware to detect that the button is pushed down from the normal position, and uses said hardware to also detect that the entertainment button is pushed down from the protruding position, wherein: 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; and when the character determining part determines the character, the display part displays the determined character.
