Abstract
An apparatus and method for cleaning an informational tape carried in a tape cassette. The cassette is positioned within a cradle defining a rear wall. Mounted to the wall for rotary movement thereon is a bobbin wrapped with cleaning fabric. Coaxially secured to the bobbin is a ratchet wheel and positioned for actuation of the ratchet wheel is a drive pawl. The drive pawl is carried by a pawl arm mounted for substantially linear movement in response to the placement of a tape cassette within the cradle. Positioning of the cassette within the cradle imparts linear motion to the pawl arm causing the bobbin to incrementally rotate exposing a clean segment of the cleaning fabric to the informational tape.
