According to a first aspect of this invention, it is assumed that the recording is carried out on the recording medium by a non-catalyst-containing recording agent and a liquid-state catalyst is coated on the recording medium at the time of erasing processing and subsequently the heating and irradiation of near infrared rays are carried out as the erasing processing. Also, according to a second aspect of this invention, it is assumed that the recording is carried out on the recording medium by a catalyst-containing recording agent and, at the erasing processing time, the heating and irradiation of the recording agent are simultaneously carried out using a thermal emission and near IR irradiation source such as a halogen lamp.

Erasing method

Erasing method and erasing apparatus for performing that erasing method

One of a ribbon feed roller (32) and a pressure roller (34) for making an endless ink ribbon (30) run is displaceable relative to the other roller thereof for facilitation of replacement of the ink ribbon, and can be locked at a withdrawn position thereof. In a state where one roller is locked at the withdrawn position, mounting of the ink ribbon cassette on a printer is obstructed. Also, a running direction and an orientation of the endless ink ribbon are defined so that damage to the bonded portion of the endless ink ribbon is delayed as much as possible.

Ink ribbon cassette

An ink ribbon for a printer, particularly an impact type printer such as a wire dot printer or daisy wheel printer, as well as a black ink to be used for an ink ribbon for a printer.
