Abstract
A ribbon and correction tape are separately mounted on a typewriter for movement in closely spaced parallel planes from a position below a line of impact along a line of print to an elevated position opposite said line of print. To minimize interference and malfunctions during relative movement of the ribbon and tape during elevating movement of one, the ribbon and tape are supported at an acute angle to one another, thereby to move in scissor fashion relative to the other.
