Abstract
A voting machine employs a scroll-type multi-layer ballot structure including removable strips carried by the upper layer and a pressure responsive means in the lower layer to reproduce markings made on the removable strips. Each removable strip carries a voter number so that an audit of each ballot can be made by the voter without revealing his identity. The multi-layer scroll-type structure is carried behind a panel having a slot therein extending in the direction of the removable strips and a door covering the slot which is prevented from opening to provide access to the strips in response to operation of the mechanism which senses whether or not a strip has been removed.
