ABSTRACT:
A wiping device for a magnetic tape cassette is provided with an elastic main body having a securing element cooperable with a cassette housing so that the main body can be mounted to and removed from the housing from the outside of the cassette without dismantling the secured upper and lower cases. A wiping or cleaning/erasing element is supported by the main body and has a curved operation surface. When the main body is mounted to the housing, and the magnetic tape is loaded to an operation position by a magnetic recording and reproducing apparatus, the magnetizable surface of the magnetic tape contacts an effective area of the curved operation surface. When the magnetic tape is loaded and moved by the apparatus, the magnetic tape exerts an urging force to the wiping element, and the elastic main body urges the wiping element to exert a predetermined urging pressure to the magnetic tape against the urging force, so that the effective area of the curved operation surface can snugly contact the magnetizable surface to perform tape cleaning and/or erasing processes.
