ABSTRACT:
Apparatus is provided for operating a dictation unit as a telephone-answering device. The dictation unit has a movable record medium upon which an announce message is recorded at a predetermined portion. Switching circuitry is selectively operable to condition the dictation unit to operate as a telephone-answering device, and a line coupler connects the dictation unit to a telephone line. An activate arrangement is operable when the dictation unit is conditioned to operate as a telephone-answering device to respond to an incoming ringing signal on the telephone line for activating the movable record medium to advance at a playback speed so as to transmit the announce message over the telephone line and, at the conclusion of the announce message, to advance to the next available recording portion thereon to record an incoming message. In a preferred embodiment, the dictation unit is operable either as a telephone-answering device or as a remote dictation machine wherein the record medium is advanced at a recording speed to record an incoming message thereon in response to an incoming telephone call. In the telephone-answering mode, the record medium is rewound to the beginning of the announce message thereon at the conclusion of each incoming telephone call, thus being in condition to transmit that same announce message in response to the next incoming telephone call. After the announce message is transmitted, the record medium is advanced rapidly past all previously recorded incoming messages until the next available recording portion is reached.
