The hopper includes a cavity(7) and supplies coating medium through two or more supplying lines(12) with a volume flux adjusting unit. The flow channel discharges the coating medium in a curtain shape through an exiting slot. The flow channel is divided by a plurality of expanding guide channels of a diffuser block.
