<p>A reusable sheet medium is provided. It includes a repeatedly erasable information recording layer (15a), which comprises a waterproof layer (15a1) and a paper core layer (15a2). An erasing device for the reusable sheet medium and an information recording processing system including the erasing device are also provided. The erasing device includes an erasing liquid container (c1) and an erasing actuating mechanism (c2), the erasing actuating mechanism (c2) comprising an erasing element (c21) which is communicated with the erasing liquid container (c1) by a guiding pipe (c3). By cooperation of the erasing liquid container (c1) and the erasing actuating mechanism (c2), erasing processing on the reusable sheet medium can be automatically realized in low cost. The operation is convenient and effective, thus reducing the resources and being of benefit to environmental protection.</p> |
