Abstract
Tape partially curves around a one-way tape brake for a cassette. The brake has a cylindrical roller with a side extension. When the tape advances, a smooth cylindrical side of the roller allows tape forward movement. When the tape tends to reverse the tape pulls a friction surface rearward, turning the roller and frictionally engaging the tape and pinching it against a tape guide. Rearward tape motion is prevented.
Claims20
A single play tape cassette apparatus comprising a tape, a source of tape within the cassette, and spaced guides guiding the tape and around which the tape moves for presenting the tape to an information pickup head, and having a takeup roll connected to the tape for winding the tape and advancing the tape in a forward movement from the tape source and around the tape guides, a pivoting one-way tape friction brake positioned on a side of the tape opposite from one of the guides, the pivoting brake having a smooth lubricating surface and structured for presenting said smooth surface for contact with the tape during forward tape movement, and having a high friction surface on an extension structured for engaging and braking the tape against said one guide upon attempted rearward tape motion to prevent the tape from moving in the rewind direction.
