Abstract: A refrigerated showcase of which the slide doors can be automatically opened and closed without producing much noise which is annoying to both cooks and diners. The showcase includes a showcase body having a work side through which a cook can access the interior of the showcase by opening slide doors, and a transparent display side. The slide doors are opened and closed by two electric motors arranged one over the other through cables which are supported by a pair of independent sheaves rotatably mounted on a common shaft. Each cable is coupled to one of the slide doors through a coupling arrangement including a cushioning member such as a pair of springs.
