ABSTRACT:
A powered gear driven paper insert and line feed mechanism capable of rotating a platen through one half line spacing increments and which is both power operated and disconnectable for manual operation is disclosed. The platen of the typewriter or printer may be manually rotated using platen or may be electronically rotated by energizing the control magnet, thus engaging the clutch assembly to connect the drive motor to the platen. The clutching assembly is such that two separate clutches are operable to disconnect the platen and gear train from the overall clutch apparatus and also to disconnect the drive motor belt and other related hardware which is driven by the drive motor and belt.
