ABSTRACT:
An improved tape drive system for an apparatus (a telephone answering device in the exemplary, preferred embodiment of this invention) which employs one or more dual reel tape cassettes or cartridges. The tape drive system of the present invention requires only a single motor and a single solenoid for providing all operating functions of the apparatus. One lever (a broadcast lever) is pivotably mounted on a base or chassis and carries a broadcast pinch roller mechanism and a broadcast record/playback head. A second lever (an incoming call recording or "ICR" lever) is pivotably mounted on the first lever and carries an ICR pinch roller and an ICR record/playback head. The broadcast, ICR and rewind operating modes of the apparatus are provided by a single motor and a single solenoid.
A novel one-way clutch mechanism employs an eccentric disc or cam for camming the broadcast pinch roller out of engagement with the broadcast tape drive capstan during the rewind mode of operation of the apparatus, without the need of a separate solenoid.
A novel automatic ICR tape reversing mechanism is employed for driving the take-up reel of the ICR cassette during the ICR mode of the apparatus and for driving the supply reel of the ICR tape cassette during the rewind mode of the apparatus, without the need of separate solenoids.
