Abstract
A device for erasing a used ink ribbon comprises a heater. The heater is provided on a dye layer side of the ink ribbon at the downstream of a printing apparatus and contacts with the dye layer of the ink ribbon. The information remaining on the used ink ribbon can be erased through directly melting and eliminating the dye on the ink ribbon by the heater. The present invention makes the recycle of the used ink ribbon be safer and more reliable, and effectively prevent confidential or private information from being divulged by the discarded used ink ribbon.
