Abstract
The mechanism is for use with a tape recorder of the cassette type in which the direction of rotation of tape reels within a cassette is automatically reversed at the end of taking up the tape. A drive gear is movably supported between a pair of driven gears engageable with the respective reels, so as to be able to engage with either one of the driven gears, and the drive gear is spring biased toward a line connecting the rotating axes of the driven gears. The rotation of the drive gear in one direction causes its engagement with the corresponding driven gear and, at the end of taking up the tape, a substantial displacement of the drive gear against, the spring bias occurs through an increase in load, thereby changing over the direction of rotation of a motor for driving the drive gear. A mechanism is provided for resetting or maintaining the drive mechanism in a given condition which enables the reels to start to rotate in a given direction whenever a tape cassette is removed from the recorder.
