Abstract: Disclosed is an indicator device for visually denoting the amount of filled dust in a dust container of a vacuum cleaner. The indicator device operates based on a vacuum pressure difference created between an air suction port and an outlet of the vacuum cleaner. When a vacuum pressure difference is created between the air suction port and the outlet of the vacuum cleaner, a disc-shaped colored film and a circular rotating member positioned in an upper cap of the indicator device receive an atmosphere air from the exterior of the indicator device and denotes the amount of dust filled in the dust container. For this purpose, a colored film is separated by 3.times.N (N is an integer) times and colored in three primary colors of light of red, green and blue or in three primary colors of red, yellow and blue.

The cool air in the fresh food compartment is directed toward the door by the blowing fan, so the cool air is uniformly distributed in the fresh food compartment. Furthermore, the cool air drawn into the door duct is supplied into pockets formed inner side surface of the door through the cool air discharge port, so the inner space of the pockets are effectively cooled.

Abstract: An image forming apparatus that includes an image reading section, a transportation path, a photoreceptor, transferring area, a fixing area, and a feeding speed controller. The feeding speed controller selects the speed at which an original document passes through the image reading section between two speeds. A first speed is used when the transfer sheet is normal sized and for a period of time prior to a large sized sheet entering the fixing area. Once a large sized sheet enters the fixing area, the feeding speed controller changes the speed of the original document from the first speed to the second speed to provide proper scaling of the reproduced image on the transferred sheet. The second speed may be adjusted depending on the type of transfer sheet being used to take into account the amount of stretching of the material used to make the transfer sheet.
