To prevent wasteful power consumption by a heater and a decline in cooling efficiency by reducing the labor involved after closing a store and preventing the failure in turning off a fluorescent lamp.

A refrigeration-cold storage show case is equipped with a fluorescent lamp 1 which lights an article storage space or the like and a night cover 3 which is stored in a storage space when a store is open, and is drawn out to practically cover the front face after closing the store. The refrigeration-cold storage show case is provided with cover detection switches 15-1 to 3 which are interlocked by drawing out the night cover 3 to switch the point of contact, and the power of the fluorescent lamp 1 is turned off based on the switching of the contact point of the cover detection switches 15-1 to 3. Moreover, based on the switching of the contact point of the cover detection switches 15-1 to 3, the power of a condensation prevention heater 5 which is provided at a reflector 4 for the fluorescent lamp 1 provided closely to a cold air discharge opening 11 is turned off.
