Abstract
The device records images in the form of dots on electrical discharge-sensitive paper. Multiple styli are mounted on a rotor. This divisional patent is directed to the paper feed means in which the paper is fed past the styli through a concave guide. The housing of the device is cylindrical with a curvature to match that of the concave guide, and is used both as a housing and as a convex paper guide. A drive roller extends through an opening in the cylinder wall to make contact with the paper. An idler roller on the other guide member mates with the drive roller to grip the paper. The concave guide member is hinged to the housing so as to be movable out of the way to facilitate threading the paper through the machine at the start. The rotor rotates within a cylindrical platen of a diameter larger than that of the housing. The paper moves from the outside of the housing to the inside of the platen, where images are formed on the paper by the styli.
