PURPOSE:To facilitate maintenance, etc., of a wet air generaor and the supply of a humidifying liquid by making up a humidifier from an air supply pump to an air jet nozzle and a wet air generator provided on the suction side of the air supply pump. CONSTITUTION:In the case of dried open air, a shutter 17 is moved upwards, and the open air is sucked into an air suction port 16 and given moisture from a humidifier 19 provided to an wet air generator 18. The wet air is sucked from a wet air supply pipe 20 into an air supply pump 6 and supplied to an ink jet head 1. When the open air is of a high humidity, the shutter 17 moves downwards, the open air is directly supplied from the hole 17a of the shutter 17 into the air supply pipe 8, and the path from the wet air generator 18 to the air supply pipe 20 is closed. The humidifier 19 is made up of a moisture absorbable material, e.g., sponge, etc., and absorbs a humidifying liquid 21, keeping a humidified state all the time. |
