ABSTRACT:
The present invention relates to a printing apparatus, and more particularly to an arranging structure in which an ink ribbon extended from a ribbon cassette is arranged between a platen and a print head. The printing apparatus comprises a platen rotatably supported on a frame, a print head capable of moving reciprocally along the platen, a ribbon cassette replaceably loaded at one end side of the movable range of the print head and housing an ink ribbon with some portion extending outwardly as a loop, and a ribbon guide body located inside the loop of the ink ribbon and for pulling out the same. The ribbon guide body is movably provided along the platen and enters inside the loop of the ink ribbon when the ribbon cassette is mounted on the frame with the ribbon guide body located at one end side of the movable range of the print head. Further, when the ribbon guide body is moved to the other end side of the movable range of the print head as it is placed inside the loop, the loop of the ink ribbon is pulled out in a long strip with the loop guided on the ribbon guide body. Subsequently, the ribbon guide body is locked at its predetermined position.
