Abstract
A copy sheet-feeding apparatus comprises a switch and control mechanism. The switch detects an open state of a sheet cover capable of exposing a stack of copy sheet and a closed state of the cover sheet capable of enclosing the stack, and generates signals denoting the open and closed states of the sheet cover. The control mechanism controls a drive mechanism for moving a sheet rest supporting the stack of copy sheets between a first position capable of receiving the copy sheets and a second position capable of supplying the sheet to a copying press. Receiving the signal denoting the open state of the sheet cover from the switch, the control mechanism causes the sheet rest to be moved to the first position, and, receiving the signal denoting the closed state thereof, causes the sheet rest to be moved to the second position.
