ABSTRACT:
A sheet feed device for feeding sheets from a stack to a machine, such as a copier, is provided with rollers for feeding the top sheet of the stack to the entrance of the machine. When a sheet is being fed through the machine, the presence of the sheet is sensed and used to generate a signal to disengage the rollers from the stack to thereby ensure precise feeding of the sheets.
