Filed: 1984-02-07
Abstract: PURPOSE:To prevent a poor quality of printing and skewing completely by providing a sub-auxiliary guide plate in a clearance between a platen and an auxiliary guide plate to support the auxiliary guide plate with the sub auxiliary guide plate. CONSTITUTION:A sub-auxiliary guide plate 10 is made of material lower in the rigidity and friction resistance, for example, polyester film and the base end thereof is fastened on the auxiliary guide plate 6 being supported in a natural condition.
