Abstract
A shredder includes a housing having a throat for receiving articles be shredded and a shredder mechanism. The shredder mechanism includes a motor and cutter elements, and enables the articles to be shredded to be fed into the cutter elements. The motor drives the cutter elements to shred the articles. A cam mechanism is provided in the throat and is movable from a disengaged position to an engaged position responsive to insertion into the throat of articles above a predetermined maximum thickness threshold. In the engaged position, the cam mechanism engages the articles to prevent further insertion thereof into the throat, and in the disengaged position the cam mechanism is disengaged from the articles to permit further insertion thereof into the throat. The cam mechanism may be movable between a closed position and an open position. In the closed position, the cam mechanism is configured to block the throat.
