Heat transfer recording with automatic ribbon take-up positioning/driving means

摘要

An apparatus for use with a cassette having accommodated therein an ink material, a feed roller and a take-up roller for the material. A pair of driving heads in the cassette loading portion of the apparatus are automatically connectable to or disconnectable from the opposite ends of the take-up roll by spring levers which are movable in response to the loading or unloading of the cassette. When connected to the take-up roll, the heads center the take-up roll and position the roll in place axially thereof. The feed roll is positioned in place by V-shaped bearings in the loading portion. Thus, the two rolls can be positioned accurately automatically without necessitating any special procedure.
