PROBLEM TO BE SOLVED: To use a power source other than an external power source or a battery as the power generation source of a light emitting unit in a pinball game machine with a movable object provided with the light emitting unit. SOLUTION: The pachinko game machine PM has a performance device 60 provided with a storage box 61 and provided on a game board 10 for driving the storage box 61 and executing a prescribed performance operation, the storage box 61 stores the plurality of light emitting units 51 inside, the storage box 61 is driven and the light emitting units 51 are rolled and moved inside the storage box 61. Then, the light emitting unit 51 is constituted of a piezoelectric bimorph element 53 provided on an outer surface forming the light emitting unit 51 and deformable by a collision with the storage box 61 or the collision of the light emitting units 51 with each other by rolling movement, and a light emitting diode 55 disposed inside and capable of emitting light by receiving the supply of electromotive force generated in the piezoelectric bimorph element 53 by the deformation of the piezoelectric bimorph element 53.
