ABSTRACT:
A tape cleaning apparatus for a tape recording and/or reproducing apparatus prevents possible dropping of recording or a possible dropout during recording and/or reproducing operation of a tape while the tape is fed at a low speed and can protect the tape when the tape is fed at a high speed to effect fast feeding or rewinding thereof. The tape cleaning apparatus comprises a blade made of an abrasion resistant material and located on the upstream side of a recording and/or reproducing section of the tape recording and/or reproducing apparatus in a direction in which the tape is fed at the low speed. The tape cleaning apparatus also includes a controller for controlling the blade to assume a first position at which the blade contacts with the tape to remove foreign substance sticking to the tape when the tape is fed at the low speed but to assume a second position at which the blade is spaced apart from the tape when the tape is driven at a high speed.
