Abstract
A tension adjustment device includes a swing arm having a central portion defining a pivot point; a tape guide rod sleeved rotatably on a left portion of the swing arm; a stop block disposed on the swing arm; a biasing member having one end fixed to a fixing element and a second end biasing the swing arm; a carrier disk disposed adjacent to and biased by the stop block; and a reel of carbon tape mounted on the carrier disk, and having a carbon tape with a predetermined tape section trained around the tape guide rod in such a manner to be dispensed outward along a dispensing path. During the dispensing operation, a total tension force is generated on the tape guide rod due to two tension forces caused by trained on of the predetermined tape section, wherein, the stop block disengages from the carrier disk.
