<P>PROBLEM TO BE SOLVED: To improve performance properties of light using a half mirror to expand the range of a performance. <P>SOLUTION: This half mirror performance device 1 includes: a rotor 3 having performance ports 2a-2c; a drive part 4 driving the rotor 3; a guide path 5 for guiding a game ball to the performance ports 2a-2c; the half mirror 6 covering the rotor 3; and an illumination part 7 illuminating the inside of the half mirror 6. A ball can enter one performance port 2a of the performance ports 2a-2c of the rotor 3. A game ball cannot enter the other performance holes 2b, 2c by covering the surfaces of holes of the other performance ports 2b, 2c with transparent sheets 8. <P>COPYRIGHT: (C)2013,JPO&INPIT |
