PROBLEM TO BE SOLVED: To provide a button type performance operation device for a game machine, wherein ingenuity is exercised to largely project a button part in two stages and a player is made to strongly recognize the projection of the button part.SOLUTION: When an operation body 40 is at an original position, a driven member 51 is maintained in the state of being engaged with a roller 55, and a coil spring 52 is maintained in a compressed state. When a disk 54 starts to rotate in one rotating direction by a cam driving motor 53 while the operation body 40 is at the original position, the slidable contact state of the roller 55 with the driven member 51 is released, the coil spring 52 is released from the compressed state, the operation body 40 is moved upwards to an upward movement initial position by the elastic biasing force, and then the roller 55 drives the driven member 51 to move it upwards so that the operation body 40 is moved upward to an upward movement end position. |
