ABSTRACT:
An apparatus for guiding a carbon ribbon from a supply reel to a take-up reel includes an adjusting member which is used for securing a guide rod around which the carbon ribbon passes to a fixed plate. A bolt passes through an off-center hole in the adjusting member and upon tightening of the bolt, one end of the rod is secured to the fixed plate. The other end of the rod is pivotably secured in a base plate. Therefore, by turning the adjustment member, the location of the off-center hole is changed and the inclination of the rod is adjusted. By suitable setting of the adjustment member, the orientation of the rod is adjusted so that a uniform tension is applied across the ribbon tape to thereby prevent wrinkling or misalignment thereof.
