ABSTRACT:
An ink ribbon cassette repeatedly usable for an extended period of time by replenishment of ink to an ink ribbon after each printing operation. The cassette includes a cassette casing, an ink-storing member disposed within the cassette casing and storing ink liquid as absorbed therein, an ink-absorbing member disposed within the cassette casing for absorbing the ink liquid from the ink-storing member through contact thereof with the ink-storing member. A wall member is disposed within the cassette casing and encasing the ink-storing member and the ink-absorbing member, the wall member defining an opening for allowing a portion of the ink-absorbing member to be exposed therethrough to the outside. A replenishing roll is provided to be rotatable while elastically contacting the ink-absorbing member through the opening so as to replenish the ink liquid to an ink ribbon being moved. The ink-storing member and the ink-absorbing member together form a gap at mutually contacting portions thereof registered with the opening so as to allow flection of the portion of the ink-absorbing member toward the ink-storing member in association with the contact therebetween.
