Therefore, when the shutter 5 is in the closed state, the limit switch 36 is actuated and can stop rotational driving of the stepping motor 6. At this time, because the shutter 5 in the closed state maintains the closed state by utilizing pressure of the air flow, there is no danger of air leakage around the periphery of the shutter 5.

Therefore, in a state in which the space in front of the bottom intake port 11b and the space in front of the bottom discharge port 25 are divided by the front edge 53, the air flow B1 whose direction is changed by the projected portion 52 is blown out forwardly downward from the bottom discharge port 25. Thereby it is possible to reliably prevent short circuit between the bottom intake port 11b and the bottom discharge port 25.
