Abstract
Motor-driven cutting apparatus for cutting sheet media are disclosed, particularly for use with plotter and printer apparatus. The cutting apparatus of one embodiment comprises two cutting members in which at least one of the cutting members is moved both angularly and linearly, e.g., pivoted and reciprocated, relative to the other to cut media placed between the two cutting members. In another embodiment, the cutting members are both simultaneously pivoted relative to each other. Rotary motion of a driving member, e.g. a motor shaft or a shaft coupled to a motor shaft, is converted to combined angular and straight line motion or only angular motion at one or both cutting members by a simplified coupling arrangement which may comprise simple sleeves with eccentric structure and pivot-type joints. Cutting apparatus according to the invention may be used for X-axis and/or Y-axis cutting.
