<p>A method and device for directly positioning and holding media against an output platen while a cutter traverses across a media path. A cutter assembly is mounted on an arm which periodically passes over the media, and includes a cutter blade (108) and at least one media restraint wheel (118) which presses the media against the output platen. The media restraint wheel (118) is located in close proximity to the cutter blade (108), such that the media restraint wheel (118) is upstream from the cutter blade (108) and also is laterally displaced from the cutter blade (108) to achieve direct engagement of the media by the media restraint wheel (118) prior to cutting the media. The media restraint wheel (118) includes a soft rubber-like tyre which rolls along a top surface of the media while rotating freely on an vertically adjustable axle (126), in order to accommodate both thick and thin media, without the need for a separate media hold-down device. A biasing spring (120) presses downwardly against the axle (126) to assure secure holding of the media against the output platen. Preferably, at least one opposing wheel (114) upstream from the cutter blade (108) is provided on the cutter assembly for rolling engagement with the output platen to assure proper positioning of the cutter blade (108). <IMAGE></p> |
