Abstract
An apparatus for generating falling snow and having an upright inner cylinder, a cloud vapor machine and a snow seed feeder connected to the cylinder near the lower end thereof, an air velocity adjustment pipe connected between the upper and lower ends thereof and a blower in the pipe for adjusting the flow velocity of air inside the pipe to adjust the flow of air in the inner cylinder, and a cooling tower surrounding the inner cylinder and a cooler for cooling the air in the cooling tower for cooling the inner cylinder. A deposited snow removing apparatus is provided which has a plurality of vibrators on the inner cylinder for vibrating the wall of the inner cylinder for removing snow deposited on the inner surface of the wall of the inner cylinder, a projector directing light into the upper part of the inner cylinder against the inner surface of the wall of the inner cylinder, a light receiver for receiving light reflected from the inner surface of the wall of the inner cylinder, and an operating device connected between the light receiver and the vibrators for operating the vibrators in response to the amount of light received in the light receiver.
