  • Patent number: 4382705
    Abstract: A typewriter with a character erasing apparatus capable of consecutively erasing a series of characters as well as a single character once printed on a sheet of printing paper. The typewriter is provided with a retaining crank movable to first, second and third positions. In the first position the retaining crank retains a ribbon vibrator supporting an erase ribbon in non-operative status. In the second position the retaining crank permits the ribbon vibrator to operate while interrupting transmission of power for moving a platen. The retaining crank is automatically restored to the first position in response to return movement of the ribbon vibrator after the single character erasing. The retaining crank is moved to and held at the third position by a manual member for permitting the ribbon vibrator to operate consecutively. The retaining member does not interrupt the transmission of the power for moving the platen.
