Abstract
The present invention relates to a shredder that includes a housing having a movable part that forms at least a part of an opening for the insertion of articles to be fed into the shredder. A detector detects motion of the movable part, and in response, a controller performs a predetermined operation, including, for example, stopping cutting elements of the shredder mechanism.
