ABSTRACT:
In a tape drive having a supply reel and a take-up reel, a drive mechanism for advancing and rewinding the tape includes a platform generally disposed between the reels. The platform is pivotally mounted for free pivotal movement in a plane between first and second positions. The rim of the take-up reel is spaced above the rim of the supply reel. A drive disc, rotatably mounted on the platform, is frictionally engaged with a shaft of a reversible motor. The drive disc includes concentric smaller and larger diameter discs spaced from each other along their axes and fixed to one another for simultaneous rotation. The larger diameter disc is disposed at the level of and is engageable only with the rim of the supply reel and the smaller diameter disc is disposed at the level of and is engageable only with the rim of the take-up reel. The position of the drive disc is determined by the direction of rotation of the motor shaft. The smaller diameter disc moves to the first position to engage the take-up reel and turn the latter when the motor shaft turns in one direction. The large diameter moves to the second position to engage the supply reel and turn the latter when the motor shaft turns in the other direction. In this manner, rewinding of the tape, by turning the supply reel, is at a higher speed than advancing the tape by turning the take-up reel.
