    摘要： A blackboard eraser including a cube having two semi-cylindrical grooves symmetrically arranged in a longitudinal direction therein, and a central brush atop an elevated surface formed between the two grooves. A longitudinal groove is defined underneath each of the send-cylindrical grooves, and equal-length side brushes, which are affixed to an inner surface of a lid, are respectively positioned in the longitudinal grooves. Two grooves are arranged adjacent to each end of the semi-cylindrical grooves, which provide for a shaft affixed to each end of a roller to dispose therein. The brushes and the rollers form the eraser, which are enclosed within a closed chamber between the lid and the two semi-cylindrical grooves. When erasing chalk dust from a blackboard, the chalk dust sticks to the rollers and is carried to the side brushes. The side brushes then wipes the dust, which falls into the closed chamber.

    摘要： A novel structure for a blackboard eraser is provided wherein the eraser comprises a plurality of raised rows of two or more different erasing mediums such as brushes, fiber or cloths laterally spaced and extending parallel on a base support to form an eraser body. The body is connected at its two ends to a resilient dust-collecting frame flush with the raised erasing mediums so that when erasing the blackboard with the eraser the latter completely encloses the corresponding part of the blackboard, guiding the dust along the spaces between adjacent raised rows of erasing mediums and then collecting them in the frame, thereby preventing the dust from flying about and polluting the air. A chalk container may further be formed at the lower part of the eraser for holding the chalks.
