Abstract
A paper clearing device for a shredder includes a frame, a motor, a gear set, a first rotary shaft, and a second rotary shaft. The first rotary shaft and the second rotary shaft are mounted with several cutting blades and paper guides. The paper guides on at least one rotary shaft are half paper guides. When paper jams in the shredder, the user only needs to issue a paper back command, which causes the rotary shafts to rotate in a reverse direction, causing paper to back away from the cutting region between the cutting blades and instead pass over the respective shaft with the half paper guides, optionally with the assistance of a paper clearing driver, and through an opening at the back, non-cutting side of the respective shaft to fall into a trash bin from which the jammed paper can be readily removed.

A paper clearing device for a shredder, comprising:
- a frame, a motor, a gear set, and a first rotary shaft and second rotary shaft disposed in parallel and driven by the gear set;
- the motor, the gear set, the first rotary shaft, and the second rotary shaft being installed on the frame;
- the first rotary shaft and the second rotary shaft each having mounted thereon a plurality of cutting blades and paper guides;
- a paper inlet being formed above the cutting region between the oppositely rotating cutting blades;
- and a shredded paper outgoing passage being formed below the cutting region;
- wherein all of the paper guides of at least one rotary shaft are half paper guides arranged without paper backing guides that prevent paper from passing over the cutting blades;
- wherein when a paper backing command is issued due to a paper jam, the cutting blades rotate reversely to bring paper back up to escape from the cutting point of the cutting blades;
- the reversely rotating cutting blades then causing the paper to pass over the cutting blades toward an outer side of the half paper guides away from the cutting region.
