Apparatus for wrapping paper via a tape cutter around a cylindrical drum

摘要

Disclosed is an apparatus for wrapping paper on a cylindrical drum for use in a recording or reading system. The apparatus includes a roller for pressing the paper wrapped on the cylindrical drum. The roller is disposed in the vicinity of the cylindrical drum and in parallel to the axis of the cylindrical drum and is supported by a pair of roller-supporting plates disposed facing each other. Also included is a connecting rod disposed in parallel to the roller. The connecting rod penetrates a through-hole made in a substantial center portion of each of the roller-supporting plates and is supported by a pair of rod-supporting plates disposed outwardly with respect to the pair of roller-supporting plates. A lever is mounted on an end of at least one of the roller-supporting plates, which end is opposite to the other end where the roller is supported, so that the roller is rotatable about the axis of the connecting rod with the operation of the lever. The pair of roller-supporting plates are biased by a pair of springs so that the roller is pressed toward the cylindrical drum.
