Abstract
A tape cassette includes one or more manually settable slider elements that are detected to prevent erroneously erasing information recorded on the cassette. The element slides in a through hole in the cassette case and includes stop surfaces that limit the travel of the slider element by cooperating with protrusions or shoulders that are formed by the respective half cases making up the cassette case. The slider element also includes a click-stop protrusion that cooperates with a protrusion in the through hole that is formed in only one of the two half-cases. The slider element further includes a through slot that permits deformation of the slider element as the click-stop protrusion goes over the protrusion in the through-hole, thereby requiring less force to move the element. The stop surfaces can be formed by two spaced apart protrusions that also permit deformation of the slide element as the click-stop protrusion travels past the protrusion in the through-hole.
