Abstract
An apparatus positions a rotary drum having an axis of rotation in an image scanner having a frame to position an image source mounted on the rotary drum. A way is mounted to the frame. A headstock and a tailstock are disposed and arranged to receive and support the rotary drum and are independently mounted on the way for lineal movement along the axis of the drum. A drum drive device rotates the drum about the axis and a headstock drive device linearly moves the headstock along the axis in first and second opposite directions. A stop block is supported by the frame and impedes a linear movement of the tailstock in the second direction at a selected stop position. A connector connects the headstock to the tailstock to cause the tailstock to move linearly along the axis in response to the movement of the headstock and includes a disengaging mechanism to disengage the tailstock from the headstock when the tailstock is at the selected stop position to permit the headstock to continue to move in the second direction.
