Ribbon rewinding mechanism for providing stable ribbon tension in a printer
A ribbon rewinding mechanism for providing stable ribbon tension in a printer includes a base body, a supply shaft assembly, a take-up shaft assembly and a transmission system. Each of the supply shaft assembly and the take-up shaft assembly has an axis rod, an outer cover and an elastic member. The outer cover and the axis rod drive each other through the elastic member. The outer covers of the supply shaft assembly and the take-up shaft assembly are connectable to the two ends of a ribbon, respectively. The axis rods of the supply shaft assembly and the take-up shaft assembly are connected to the base body and the transmission system through unidirectional transmission elements, respectively, so that the ribbon can be stably and continuously rewound for a distance needed.
