PROBLEM TO BE SOLVED: To reduce the manufacture cost by simplifying the constitution of a smoke separation system. SOLUTION: The size of an air curtain formed with the smoke separating apparatus is set so that the horizontal width dimension of the air current of 0.3-0.6 m/s is about 15-20 cm and a front-back width dimension is 35 cm or larger on a horizontal plane roughly equal to the height of the mouth of a player and they are equivalent or larger on a horizontal plane roughly equal to the height of a motor-driven handle as well. Further, the horizontal width dimension of the air current of the wind speed 0.6 m/s or higher is set to be about 15-20 cm. COPYRIGHT: (C)2008,JPO&INPIT
