Control system for thermal printing typewriters or like machines |
摘要 |
A typewriter having a thermal print head defining an array of print elements and a thermal print ribbon, both of which are supported on a carriage movable relative to a platen, is provided with a control system which responds to a character print command to move the print head into controlled pressure contact with the platen and to engage a substantially play free clutch for coupling carriage movement initiated by a print command to advance ribbon opposite the direction of carriage movement whereby relative movement between said ribbon and platen is avoided during printing.
