| abstract |
Apparatus for indicating a predetermind position on a filament such as a magnetic tape transported between supply and take-up reels. Such a predetermined position is representative of the amount of usable recording medium remaining on the supply reel from which the tape is spooled. The apparatus is characterized by the provision of a normally operating signal source and means for blocking the signal. The blocking means is removed upon achievment of a predetermined change in velocity of one of the reels occasioned when almost all of the tape has been removed from the supply reel to provide a warning alerting an operator that the predetermined quantity of tape remains on the supply reel. |
