Abstract
The present invention provides a shredder, which has a housing, an entry slot on the housing for inserting a desired medium, a shredding device installed inside the housing for shredding the medium, and a central trigger for sensing the medium and therefore triggering the shredding device. The shredding device has a shredding gap between two shredding knives. The central trigger is installed above the central portion of the shredding gap. The shredder further has a side trigger installed between the central portion and an end of the shredding gap. When a large medium is inserted into the entry slot, the medium will trigger the central trigger device and therefore trigger the shredding device. However, when a sufficiently short medium is inserted into the entry slot, the medium is capable of triggering only the side trigger, and therefore triggers the shredding device.
