2. Description of the Related Art Open showcases in which goods are displayed in a case and sold are self-service devices that require the customer to select and display the goods displayed in the case while taking them out and purchase them from themselves. It is. So,
An open opening is formed in the case so as to be open to one side of the outer peripheral surface so that a customer can easily take out products displayed in the case. Air outside the case, including dust, can easily enter the case through this opening, and in an open showcase where products displayed in the case are refrigerated or frozen and stored in the case, the case opening should be inside and outside the case. It is typically covered with a thermally insulating air curtain. This air curtain keeps the inside of the case cool by preventing cold air, which is cold air inside the case, from leaking out of the case and warm air, which is warm air outside the case, from entering the case. However, there is a limit to the heat insulation properties of the air curtain, which thermally shields the inside and outside of the case, and some amount of cool air inside the case leaks out of the case through the opening of the case, and warm air outside the case enters the case. Therefore, invasion of heat outside the case through the air curtain is inevitable. In addition to the case where the opening is not covered with the air curtain, even in the case where the opening is covered with the air curtain, air containing dust outside the case enters the case. On the other hand, the open showcase is closed,
Particularly, at night, since products are not taken in and out of the case through the opening of the case, the opening of the case may be covered with something other than the air curtain. Therefore, in an open showcase where the opening of the case is covered with an air curtain, as a measure to prevent an increase in power consumption due to a decrease in cooling efficiency and a measure to prevent the intrusion of dust, an open showcase in which the opening is not covered with an air curtain In order to prevent the intrusion of dust, there is an open showcase provided with a night cover for closing the opening of the case when the store is closed, particularly at night. In the night cover of such an open showcase, the opening of the case is provided at one of both edges facing each other, and the opening surface is formed in a storage portion having a hole facing the other side. A winding shaft that is rotatably supported by a spiral spring and is rotatably supported. The night cover, one end of which is fixed to the winding shaft, is automatically wound through the hole and stored in the storage unit. There is a roll-up night cover. Such automatic winding type night cover,
During opening of the store, if the night cover in the storage unit can be seen through the hole, or if the storage unit is provided at the upper edge of the opening of the front opening case, the vortex that urges the winding shaft in one direction of rotation. The restoring force of the coil spring or the like is attenuated during use, and the end of the night cover, which is no longer completely caught in the storage portion, hangs down from the hole and impairs the appearance of the open showcase. In order to prevent this, an open showcase with a lid that can open and close the hole of the storage unit is known,
