Abstract:

There is provided a miniaturized document shredding device having engaging dual frictional conveyor rollers rotatably mounted within an enclosure. Fixed cutting blades are spaced across the width of the rollers and protrude through slits within the rollers to present cutting edges at the point of engagement of the rollers. In one embodiment these blades are mounted to the enclosure and protrude through the rollers, and in a second embodiment are mounted to the roller shafts between roller segments. With this arrangement, documents dropped through the top opening in the enclosure are picked up by the frictional rollers and conveyed by the rollers past the cutting blades to produce a shredded product.
