reusable writing skill / lock scoreboard for videobandkassette.

摘要

A write enable tab (12) is repeatedly movable from a first position, enabling writing on a signal storage unit, to a second position, disabling writing thereon. The write enable tab preferably includes a central body (42) and a flexible member (46) which exert force against first and second walls of a tape cassette shell. The flexible member is attached at a first end to the central body. A second end (52) of the flexible member projects into first and second depressions in the first wall when the central body is in the first and second positions, respectively.
