By Key Actuated Independently Of Carriage Feed Patents (Class 400/302)
  • Patent number: 4309118
    Abstract: A correction device for a typewriter is disclosed. The correction device includes a correction key which is linked to the escapement device which normally advances the carriage each time a key is depressed. The correction key disengages the escapement device so that the carriage is not advanced during correction of a misprinted character. Therefore, it is not necessary to backspace following the correction of the character. The correction key also causes the correction ribbon to be raised to the printing position so that it can be easily seen whether that portion of the ribbon has been used.
