Abstract
A typewriter driven by an electric motor and provided with a ribbon vibrator for moving an erase ribbon in place of an ordinary printing ribbon as an occasional substitution from original position to printing position according to operation of a printing device for common use to both to erase a mistyped character. The ribbon vibrator is normally retained in non-operative status by a retaining member, which is moved in response to depression of a correction key to a predetermined evacuation position to allow the ribbon vibrator to operate and locked there by a lock member. The lock member is associated with not only a release key but also a manual switch member for controlling power supply to the electric motor. The engagement between the lock member and the retaining member is released in response to a turning operation of the manual switch member to OFF position for automatically restoring the ribbon vibrator to the non-operative status.
