Abstract
A shredder holds a cutting blade assembly including a motor and a gear box inside its case and has a trash bin for collecting paper chips underneath the cutting blade assembly. A swinging board is provided in the vicinity of the paper outlet of the case. The swinging board is connected to a transmission axis via a shaft. One end of the transmission axis has a passive gear for receiving the rotating power from the cutting blade assembly via gears. As the transmission axis turns, the swinging board is driven by the shaft to perform a reciprocal motion so that the paper chips falling from the blades are evenly distributed over the trash bin. Paper chips accumulate in an even way to maximize the space in the trash bin. This prevents the formation of chip mountain and thus the problem of paper jams.
