<P>PROBLEM TO BE SOLVED: To provide a game machine for switching between a state, in which a button body supported with respect to a button base so that it freely moves forward/backward is normally press-operated, and a state, in which it is not normally press-operated, by moving the button base forward/backward, and for performing stable press-operation of the button body and reliably detecting the press-operation when the button base is at a base forward movement position. <P>SOLUTION: The game machine includes a forward/backward driving mechanism 44 which has an electric motor 60 for moving the button base 40 forward and backward across a base forward movement position which allows normal press-operation of the button body 41 and a base backward movement position for disabling the normal press-operation. Even when the button base 40 is at the base forward movement position and force directed to the base backward movement position is input from the button body 41 to the button base 40 by the press-operation of the button body 41, the button base 40 is held at the base forward movement position. <P>COPYRIGHT: (C)2013,JPO&INPIT |
