Olfactory display and fragrance source cartridge used therein

摘要

An olfactory display 10 includes a display main body 12 and a fragrance source cartridge 14, and presents a fragrance to a range bounded in terms of time and space. A cartridge accommodation room (24) of the display main body 12 and a container main body (80) of the fragrance source cartridge 14 are formed with inclined surfaces 46 and 84 inclined with respect to an insertion direction of the fragrance source cartridge 14, and a force that pushes in the fragrance source cartridge 14 acts in a direction that an open air inlet 82 is pressed to an air supply port 54 side. Accordingly, adhesiveness of a coupling portion of the air supply port 54 and the open air inlet 82 increases, and therefore, capability of an airflow source 26 is used to the utmost, and a high static pressure is generated in the fragrance source cartridge 14 for a short time.
