PURPOSE: To prevent a pressure gradient, etc. from being produced in air blown out by supplying high pressure air from a nozzle of a high pressure pipe to the inside of a transfer passage.
CONSTITUTION: A transfer passage 2 of an air conveyer 1 is provided on its top surface with a number of air blow outlets 3 tilting toward a transfer direction, with one end of the transfer passage 2 provided with an air passage 4 forming a space for taking atmosphere in. The air passage 4 is also provided either on its side or bottom face with an opening 5 and also either to the front or rear of the opening 5 inside the air passage 4 is arranged a nozzle 7 of a high pressure pipe 6. When high pressure air is supplied from the nozzle 7 of the high pressure pipe 6 to the inside of the transfer passage 2, atmosphere is taken from the opening 5 of the air passage 4 into the transfer passage 2. As a result, the high pressure air mixes with the atmosphere to reduce the pressure of air being sent in as well as to increase the flow rate of the air sent into the transfer passage 2.
