ABSTRACT:
An ink film tension device for applying a tension to an ink film used in a color video printer comprising a fixed shaft fixedly mounted to a reel bracket, a resilience member rotatably mounted to the fixed shaft, a reel body rotatably mounted to the fixed shaft and operatively connected to the ink film, and a felt interposed between the reel hub and the reel body and adapted to operatively connect the reel body to the reel hub. The resilience member has one end fixedly mounted to the reel bracket and the other end having a protruded bent portion. The reel hub has a support hole for receiving the other end of the resilience member. To the reel bracket is mounted a stopper which is adapted to selectively engage with the protruded bent portion of the other end of the resilience member, for limiting the torsion of the resilience member and thus maintaining a tension of a predetermined level at the resilience member.
