ABSTRACT:
An improved thermal transfer printer which is so arranged that a winding motor for driving a transfer ribbon winding device in synchronization with a carriage motor is mounted on the carriage separately from the carriage motor so as to reduce the load applied onto the carriage motor, with simultaneous elimination of an engaging mechanism between a carriage scanning mechanism and the ribbon winding device.
