Ink ribbon cartridge

Abstract

Abstract PURPOSE: To stabilize the travelling of a ribbon of an ink ribbon cartridge and to prevent the fouling of hands, fingers and a blank form due to the ribbon, by a mechanism wherein the rear and the front of the ribbon is covered with a rear guide plate and a front guide plate consisting of a metallic sheet with elasticity. CONSTITUTION: A front guide plate 5 composed of a metallic sheet with elasticity is mounted in such a manner that both connecting portions 20 are inward bent and the connecting portions 20 are inserted into slits 21 and guide arms 8, 10. The front guide plate 5 is positioned between both guide arms to ensure that the concave portions of the connecting portions 20 are elastically contacted with the inwalls of the both guide arms 8, 10 by its own elastic force. An end portion of a rear guide plate 12 is elastically contacted with the front guide plate through an ink ribbon in the c direction, and holds the ribbon with moderate frictional force. Since the ribbon is shifted and conducted under a condition that the whole surface except the notches 23, 22 of the both guide plates 5, 12 is covered, the ribbon does not stain a blank form, etc. COPYRIGHT: (C)1980,JPO&Japio
