Abstract
A device for identifying an ink ribbon cartridge used in a printing apparatus includes a spool rotatably disposed in the ink ribbon cartridge and having an ink ribbon wound thereabout. A ring is mounted on the spool so as to be rotatable relative to the spool and has information marks recorded thereon. A photo-sensor is disposed in the printing apparatus in opposite relation to the ring and detects the information marks recorded on the ring.
