摘要：An improved paper feeding device, for example, for a copying machine isprovided and is capable of warning a user of the status of available copy paper sheets. Amovable support tray can be monitored to provide a measurement of the total initialheight of the paper stack and subsequent movements of this paper stack to introduceindividual copy paper sheets into a paper transport system can be correlated with theactual number of sheets that are transported. From these monitored values, it is possibleto calculate the number of sheets remaining on the stack and to provide an audible, vocalor visual display of the actual number or relative condition to warn a user.
