ABSTRACT:
A cutter assembly which traverses across a media path to make a linear cut on the media includes a pair of cooperative rotary cutting blades. An upper rotary blade is mounted for passive rotation while a lower rotary blade is directly coupled to a lower drive wheel which engages the undersurface of a media guide member. The blades are slightly overlapping at their peripheral edges, with the lower blade in a fixed position, and the upper blade spring biased in an axial direction against the lower blade. An additional media-contacting wheel is mounted on the cutter assembly to be substantially vertically aligned with the lower drive wheel, and is spring biased downwardly toward the uppersurface of the media guide member in order to assure constant rotational engagement of the lower drive wheel with the media guide member during cutting. The lower drive wheel and lower rotary blade are coaxially mounted at a slight angular declination facing upstream as compared to the direction of traverse of the cutter assembly. The media-contacting wheel is also mounted on the cutter assembly at a similar slight angular declination. Such angles of declination create a pull on the media as it moves toward the two rotary cutting blades, thereby preventing undesirable media slack.
