ABSTRACT:
A sheet separating device is particularly usable in an intermediate tray of a copier. A drive belt separates the outside sheet from a stack and feeds the sheet through a nip with a retard roller. The retard roller is braked by a motor. The motor is adjustable between a braking condition in which it prevents rotation of the retard roller when two sheets are in the nip and a free-wheeling condition in which it permits rotation when one sheet is in the nip. When applied to an intermediate tray of a copier, the logic and control of the copier knows when one sheet is left in the tray and switches the motor to its free-wheeling condition.
