Abstract
The device records images in the form of dots on electrical discharge-sensitive paper. A plurality of styli are mounted on a rotor. The paper is in strip form and is fed continuously through a curved guide in a direction perpendicular to the plane of rotation of the rotor, so that the paper is wrapped part-way around the rotor as it moves past. Characters are formed from a 5 dot by 7 dot matrix. This divisional patent is directed to the feature whereby the paper is pushed towards the rotor by means of a drive roller located closely adjacent the platen, at a location in which the paper is curved to form an arc. The drive roller is much narrower than the width of the paper, and the stiffness of the paper column which the roller pushes is relatively great. The curved exterior of the housing is used both as a housing and as a curved paper guide. A hinged guide co-acts with the housing in guiding the paper and forming it into an arc.
