Abstract

Abstract A recording medium package for use on a heat transfer printer. The recording medium package comprises: a plurality of recording sheets, an ink ribbon having a sufficient length to print all the plurality of recording sheets and formed by coating one side of a base strip with a fusible or hot-sublimable ink or with a plurality of fusible or hot-sublimable inks of different colors in color sections arranged lengthwise in a fixed sequence; a feed spool wound with the ink ribbon; a take-up spool for winding the used portion of the ink ribbon and a cassette containing the plurality of recording sheets in a pile, rotatably supporting the feed spool and the take-up spool so that the ink ribbon is extended in front of and along the surface of the top recording sheet among the plurality of recording sheets, having an opening for exposing the top recording sheet through the ink ribbon to the thermal print head of the heat transfer printer, an ejecting opening for ejecting the recording sheets one by one therethrough, and a recess for exposing a portion of the top recording sheet to ejecting means of the heat transfer printer. The cassette comprises a recording sheet case for containing the plurality of recording sheets, and an ink ribbon case for rotatably supporting the feed spool and the take-up spool and pivotally joined at one end thereof to the recording sheet case so that the recording sheet case and the ink ribbon case can be turned relative to each other.
