Abstract: An improvement in a machine, typically a photocopy machine which utilizes individual sheets of paper which are stored in the machine as a stack of sheets and having feeding means for feeding the uppermost sheet from the stack. A removable tray having a movable support member therein is normally disposed in the machine, and an elevating mechanism automatically raises the support member in the tray in order to bring the topmost sheet of the stack into engagement with the feeding means. Camming members in the tray and the elevating mechanism cooperate with each other to depress the elevating mechanism to an inoperative position when the tray is being inserted into and removed from the machine. The above improvement is equally adaptable to use as an independent sheet feeding mechanism.

Abstract: Two sheet trays are provided, one of which is fixed in position and carries copy sheets and the other of which is movable and carries original documents for transmission. The movable sheet tray is slidable over the fixed sheet tray between a retracted position and a sheet feed position. The trays are rockable in such a manner that a feed roller engages with the fixed sheet tray when the movable sheet tray is in the retracted position and with the movable sheet tray when the movable sheet tray is in the sheet feed position to feed copy sheets or original documents respectively. Movement of the movable sheet tray by the apparatus operator to the selected one of the retracted position and the sheet feed position automatically sets a facsimile transmission system in which the apparatus is incorporated to a receive mode or a transit mode respectively. A sensor is provided to the movable sheet tray to sense for the presence of original documents therein and automatically terminate multiple document transmission.
