Claim:
An improved compartment of shredder for receiving piled-up sheets, including: a pair of longitudinal movable paper press rollers applying pressure to the piled-up sheets continuously; a compartment for receiving piled-up sheets; a pair of rollers capable of feeding paper continuously and paper shredding blades located beneath the paper feed rollers; wherein, the compartment bottom is provide with a narrower platform next to the paper feed rollers, the platform being formed with a paper entry and Y-shaped guide grooves at a center thereof, and the platform being provided at two opposing outer edges with compartment bottom surfaces inclining downwards, the bottom surfaces then extending vertically upwards to form compartment sidewalls, whereby when the piled-up sheets are placed in the compartment, the paper would form opposing upward curvatures along with the inclination of the compartment bottom surfaces in accompaniment with a force applied to the paper at specific locations by the longitudinal movable paper press rollers, thereby facilitating the paper feed rollers in dragging the paper downwardly into the paper shredding blades in a smooth manner.
