Abstract: A recording head protective overlay arrangement with an alarm capability is provided. The protective overlay is continuously replenishable between the recording surface of the recording head and the recording medium and is movable in a direction opposite to that of the recording medium so as to provide a cleaning function as well as a wear-preventive function. A dispenser cartridge housing the protective overlay is provided which is specially designed to closely conform to the recording head. A pivotable cartridge holder is included for enabling the cartridge to be inserted in a position remote from the recording head and pivotable into an operative position with the recording head. The tape medium itself and various components operatively associated therewith are pivotably mounted, to provide movement of the medium into intimate operative contact with the overlay and the recording head.

Abstract: Magnetographic printing apparatus includes relatively movable component supports which provide for ready access to a magnetizable recording medium when in an access position and desirably limited length travel path, when in an operative position, for a visual image recording medium adapted to receive a toner-developed image from the recording medium. One such component support is a substrate supporting selective image-producing components for collective movement between access and operative positions and defining a portion of the visual image recording medium travel path. The remaining portion of such path is defined by components fixedly supported for registry with such movable component support in such operative position.

Abstract: A processor for developing the encoded output medium of a business machine, wherein the processing rate is greater than the encoding production rate but must proceed uninterrupted once started. The medium, usually a web of paper or other film, is projected into the processor along a guided path to a set of drive rollers. When the web is firmly grasped by the drive rollers, the drive motion is caused to cease. The web continues to be delivered, however. The guided path is established by movable walls which will allow the incoming web to fan-fold by pushing the walls aside. The drive rollers are reactivated and the web separated from the source in a closely spaced time interval, so that the portion captured in the processor may then proceed through to a finished condition uninterrupted.
