PROBLEM TO BE SOLVED: To dispose a plurality of movable bodies and to reduce a possibility of the plurality of movable bodies coming into contact with each other.SOLUTION: The game machine includes: a projector for projecting images; a first screen fixed at a prescribed position in a display unit; a second and a third screens capable of performing rotation operations around rotation shafts different from each other between a first position where the screens are outside of a projection range of the projector and a second position where the screens each are a projection object of the projector instead of the first screen; and a driving mechanism for driving each of the second and the third screens individually. Operation ranges of the second and the third screens are partly overlapping with each other, the rotation shaft of the second screen being above the rotation shaft of the third screen, the second screen, when at the first position, being disposed at a position above the first screen, the third screen, when at the first position, being disposed at a position behind the first screen.SELECTED DRAWING: Figure 53 |
