Abstract

1490062 Tape cassettes L HOYLES 11 Oct 1974 [11 July 1973 15 July 1974] 33068/73 and 31272/74 Heading B8M A tape cassette is provided with an indicator 6 visible through a window 5 in at least one side thereof to indicate the changing diameter of at least one of the tape spools 2 or 3. The indicator may be in the form of T-shaped member having a depending arm 7 and a cross-piece slidable in a groove 9 in the cassette casing. Initially, an increase in tape diameter tape on spool 2 to engage the arm 7 to slide the indicator to the right, one extremity of the cross-piece 8 being subsequently engaged by the tape on spool 2 to continue sliding movement of the indicator. The indicator may co-operate with a time scale 10. In a modification, Fig. 5 one or other extremity 15 or 16 or arms 13 and 14 co-operate, at the beginning of a winding operation from one spool to the other with the tape on one reel, while tape on the other reel contacts a portion 20 of an indicator 12 visible through the cassette window.
