PROBLEM TO BE SOLVED: To provide a device which meets the requirement of supplying at least 100 types of humanly sensible fragrance substances out of those now available in about more than hundred thousands of types, into spaces by overcoming the problem of a larger size or complication of the device unavoidably in the specialized designing of preservation containers, suction means and piping therefor to match the types of fragrance substances. SOLUTION: Areas for housing fragrance substances are formed on a flat or curved stage detachably mounted on the device. Based on coordinates of the areas where common suction heads are predetermined even for varied fragrance substances, the intended areas are moved to positions that enables suction and fragrance substances are sucked from the areas to be diffused into spaces. An increase in the types of fragrance substances can be done simply by upgrading the integration level of the shape of the stage and the areas and so, larger outline of the device is not required.
