Abstract:

An apparatus for handling media sheets in a photo-plotter includes a plurality of aligning mechanisms for precisely positioning the media sheet relative to a drum of the photo-plotter. Each aligning mechanism has engaged and disengaged positions and include a registration pin having corresponding extended and retracted positions. In the engaged position, the extended registration pins of the aligning mechanisms pass through mounting features formed within the media sheet and are engagable with a plurality of drum openings formed within the drum of the photo-plotter. The present invention ensures that the media sheet is properly placed on the drum and also precisely positions the generated image relative to the mounting features.
