    • PURPOSE:To enable printing to cover the almost entire area of ink ribbon for higher durability by moving a guide roller vertically with the rotatin of a lead cam provided on the guide roller of the ink ribbon. CONSTITUTION:Guide rollers 6r and 6l of an ink ribbon 3 provided near the both ends of a print head 7 and a printing medium 8 are inserted rotatably into a guide roller shaft 12 fixed on a substate 2 and charged in the direction of the arrow D with a spring member 13. The guide roller 6 has cam sections 6a-6c provided at the other end thereof and is engaged with a pad pin 14 provided on the shaft 12.
