如今,复印机、传真机等已成为必需的办公用品。然而它们却耗费了大量的纸张,既不那么经济,又不甚符合环保要求。针对这种现状,日本理光公司新近推出了一种奇妙的“反复印机”,其大小与一台激光印表机差不多。已经复印过的纸张通过它,上面的图文即会消失,还原成能够再次复印的白纸,如此,一张复印纸可以重复使用10次左右。这种“反复印机”的出现,适逢世界各国日益重视保护林木资源,大力提倡节 Today, photocopiers, fax machines, etc. have become necessary office supplies. However, they have consumed a lot of paper, are not so economical, and are not very environmentally friendly. In response to this situation, Ricoh Corporation of Japan recently introduced a wonderful “anti-copying machine,” which is about the size of a laser printer. The paper that has been copied passes through it, and the above image will disappear and be restored to a white paper that can be copied again. Thus, one copy paper can be reused about 10 times. The appearance of this kind of “anti-copy machine” coincides with the increasing importance attached by countries in the world to the protection of forest resources and the promotion of festivals.
