Magnetic-tape cassette with improved anti-erase arrangement |
摘要 |
A magnetic tape cassette having two parallel rectangular major walls, and an anti-erase device adjacent a corner of the housing. A slotted recess in the edge between a first major wall and the rear housing wall receives a serrated slide whose outer surface is disposed within tangent planes to the first major wall and the rear wall. The slide is integral with an anti-erase member formed of a material having a color contrasting with that of the cassette housing, slidable parallel to the cassette rear wall. In a first position an opening in the member is aligned with an opening in the rear wall, and in a second position a portion of the member is exposed to view through the rear wall opening. In one of the two positions a sensing aperture in the major wall is closed by a control element on the anti-erase member.
