ABSTRACT:
A paper shredding device for separating and shredding a carbon paper sheet from a credit card invoice slip having a first original copy separated by a carbon paper sheet from a second copy has a rectangular housing which encloses a rotationally driven cutter roller and a pair of adjacent idling anvil rollers. An insertion slot is formed in an end wall of the housing and communicates with an internal channel. A pair of vertically spaced perforated vacuum plates form ceiling and floor portions of the channel adjacent the insertion slot. Upper and lower receptacles are provided and each communicate via a slot with the internal channel. In use, the original copy and the second copy are directed respectively to the upper and lower receptacles and the carbon paper sheet is directed through the internal channel to the cutter roller for shredding. A microswitch is provided for actuating the vacuum plates and cutter roller upon insertion of a credit card invoice into the insertion slot. The cutter roller is driven by a worm gear drive shaft operatively connected to a drive motor. p
