Abstract
It is an object of the present invention to provide an ink ribbon take-up mechanism whereby a core and a pinch roller both disposed in an ink ribbon cassette are prevented from being tilted or wobbled under the tension of an ink ribbon housed within the ink ribbon cassette while a carriage is driven (during printing), thereby permitting the core and the pinch roller to be rotated in a more stable manner. The ink ribbon take-up mechanism comprises a support shaft projected from a ribbon cassette loading surface of a carriage to a ribbon cassette loading side and adapted to be inserted into an engaging portion formed on the ribbon cassette side to support the ribbon cassette, and a drive transfer member disposed rotatably on an outer periphery side of the support shaft and adapted to be engaged with the engaging portion formed on the ribbon cassette side to transmit a rotative driving force of a motor to the engaging portion.
