ABSTRACT:
A device for holding a stack of forms in a manner such that the first form in the stack is in contact with a first surface of one side of the holding device as each form is removed therefrom. In particular, the device comprises a front portion, side portions, a rear portion, a bottom portion and a top open portion to allow insertion of the forms. The front portion is fixed and is made of transparent material. The stack of forms is positioned in the enclosure between a moveable plate and the front portion of the device, the rear portion extending inwardly from the top toward the bottom portion of the device. After the forms are positioned between the front member and the moveable plate member, force exerting means are positioned between the rear portion of the device and the moveable plate member. Sufficient force is applied to the moveable plate member to maintain the forms in a compact, substantially rigid stack with the first form in the stack being forced into substantially planar contact with the front portion of the device even as the stack is depleted. As the number of forms in the stack decreases, the force exerting means moves downward in the channel area formed between the rear portion of the device and the moveable plate member maintaining substantially constant force on the stack as it is being depleted.
