Abstract
A tape mechanism which, by means of a simple mechanism, enables fast-forwarding or rewinding of the tape from its normal play/record condition, the mechanism consisting of a main chassis to which a sub-chassis is hingedly attached. The sub-chassis has mounted thereon, a capstan, a tape take-up spindle with clutch drive gear, a tape rewind spindle with gear, a rotatably mounted gear plate, an intermediate drive gear engaged with a drive gear both rotatably mounted on this plate. A selector plate, rotatably supported by the chassis which actuates a lever, in turn moves the head plate outwardly from the cassette causing the tape-head and pinch-roller to be disengaged from the tape and capstan and thereby enables the tape to be fast-forwardly wound, or enables the tape to be rewound by means of a connecting bar and connecting rod arranged to move the aforesaid selector plate, to pull and rotate the spring loaded gear plate so that the driven gear and gear driving take-up spindle become disengaged to free the take-up spindle, and engage the intermediate drive gear with the gear of the tape rewind spindle.
