    摘要: A desensitizing gum for a lithographic printing plate and a gumming up process thereof are disclosed. The gum is comprised of water having dispersed therein 5 to 35 wt %, based on the total weight of the gum, of a film-forming, water-soluble compound selected from the group consisting of enzyme-decomposed dextrine and enzyme-decomposed etherified dextrine. The desensitizing gum exerts a desensitizing action on non-image areas of a lithographic printing plate and does not cause image blinding of image areas even when the plate is stored for a long period of time.

    摘要: A structure having a shaft and a paper retaining roller mounted on the shaft for use in a printer. The structure further includes a retaining element mounted on the shaft so as to be opposed to the roller for retaining the roller in a given axial position on the shaft. The roller is rotatable about the shaft and has a flange at its one end. The retaining element has a plurality of resilient retaining arms and its one end to hold the flange rotatably. At the opposite end, the retaining element is also provided with a plurality of resilient arms which are in frictional engagement with the outer periphery of the shaft. The roller can be slid axially along the shaft when a force greater than a given magnitude is applied thereto.
