Abstract

A dual function paper shredder includes a housing having first and second paper inlets, and an interior chamber. A strip forming cutter and a shredding cutter are received inside the chamber and are adapted for cutting paper sheets. The strip forming cutter and the shredding cutter are driven by a driving unit which includes a motor and a gear mechanism. A safety cover is pivotally mounted on the housing for turning between a first position for covering one of the first and second paper inlets, and a second position for covering the other one of the first and second paper inlets.

Claims

1. A dual function paper shredder, comprising:

a housing having a top, two opposite first and second paper inlets disposed on said top, and an interior chamber;

a strip forming cutter adapted for cutting paper sheets into narrow strips, said strip forming cutter being disposed inside said chamber below said first paper inlet and being adapted to cut a piece of paper fed through said first paper inlet;

a shredding cutter adapted for cutting paper sheets into shreds, said shredding cutter being disposed below said second paper inlet and being adapted to cut a piece of paper fed through said second paper inlet;

a motor mounted inside said chamber and connected to said strip forming cutter and said shredding cutter; and

a safety cover pivotally mounted on said top for turning about an axis between a first position for covering one of said first and second paper inlets, and a second position for covering the other one of said first and second paper inlets.

2. The dual function paper shredder as claimed in claim 1, wherein said safety cover includes a curved plate having two opposite axial ends extending axially of said axis of the turning of said cover, two circumferential ends extending circumferentially of said axis and interconnecting said axial ends, and a pair of opposite arms extending downward from said circumferential ends and pivotally connected to said housing.

3. The dual function paper shredder as claimed in claim 2, wherein said housing further includes a plurality of locking protrusions projecting upward from said top of said housing between said first and second paper inlets, said safety cover further including a plurality of first and second locking recesses formed in said plate of said safety cover, said first locking recesses engaging said locking protrusions when said safety cover is in said first position, said second locking recesses engaging said locking protrusions when said safety cover is in said second position.

4. The dual function paper shredder as claimed in claim 2, further comprising a gear mechanism mounted inside said chamber and connected to said motor, said strip forming cutter, and said shredding cutter.
