摘要： A showcase includes: a casing having a front opening through which a product is picked up; a product storage located in the casing and including a shelf on which the product is displayed; a first airflow generator that sends air for a first air curtain to flow outside along the product storage; a second airflow generator that sends air for a second air curtain to flow outside along the first air curtain; and a controller that causes the first airflow generator to operate and causes the second airflow generator to reduce an output of the second airflow generator from an output at a first timing, upon arrival of a second timing when a break of the second air curtain due to disturbance is greater than a break of the second air curtain at the first timing.
