ABSTRACT:
An automatic telephone answering apparatus includes an outgoing message tape drive mechanism; an outgoing message tape switching mechanism; an incoming message tape drive mechanism; an incoming message tape switching mechanism; and an escape mechanism. The escape mechanism includes a pivotal plate coupled to an outgoing message tape slide plate. A cam is formed at a front end of the pivoted plate. A pivotal support plate engages with the cam and supports an idler interposed between a driving roller and a rewinding roller. The escape mechanism operates mechanically in cooperation with operation of the outgoing message tape switching mechanism to prevent transmission of rotational force from a motor to the rewinding roller so the incoming message tape may not be rewound during operation of the outgoing message tape switching mechanism.
