Abstract

PURPOSE:To improve the operating workability by starting rewinding of a magnetic tape immediately by the hook-off of a destination and reproducing a message in response to the input of a key code from the destination. CONSTITUTION:When the destination hooks off, a polarity inversion detection circuit 9 is operated and the hook-off of the destination is detected by a polarity inversion detection section 17, a recording/reproduction mechanism 24 is controlled by a mechanism control section 22 in response to the detection of the hook-off by the polarity inversion detection section 17 and the magnetic tape is rewound by a length of a message recorded before. When the destination hooks off and inputs a key code, the key code is sent to a DTMF receiver circuit 13. Then a microcomputer 14 checks the pass word, and when the coincidence is detected, the recording/reproduction mechanism 24 starts the reproduction of the magnetic tape and a message voice signal is outputted to a telephone line 1. Thus, the wait time for rewinding the tape is eliminated and the input of a reproduction command is not required.

Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to an answering machine that is capable of automatically transferring business matters recorded on a magnetic tape to a preset transfer destination.

<Conventional technology> In conventional answering machines equipped with automatic call forwarding function,
When the other party's message is recorded and the recording is completed and the other party goes on-hook, the device automatically enters transfer mode and dials the preset transfer destination. Thereafter, the transfer destination goes off-hook, and in response to the transmission of the password and the input of the playback command, playback of the magnetic tape is started. The magnetic tape can be manipulated by sending various commands from the transfer destination.

<Problems to be Solved by the Invention> In the transfer operation in conventional answering machines, the transfer destination goes off-hook and then sends a PIN number, and then sends a playback command, the magnetic tape is rewound, and the playback starts. It will be done. In this way, since the magnetic tape is rewound only after the reproduction command is transmitted from the transfer destination, there is an inconvenience in that the transfer destination is forced to wait for the tape to be rewound. In addition, there is the operational complexity of inputting a playback command from the transfer destination.

The present invention has been made in view of the above circumstances, and its object is to provide an answering machine that eliminates the waiting time for rewinding a tape and eliminates the need for inputting playback commands.

sent to. When the transmission of the response message is completed, the mechanical control section 22 controls the recording/reproducing mechanism 24 to enter the recording state.
Messages from the other party are recorded on magnetic tape. When the recording of the message is completed, the hook switch 3 is opened under the control of the hook switch control section 15 in response to the on-hook call from the other party, and the telephone call circuit 4 and the telephone line 1 are disconnected.

A few seconds after the recording of the message is completed, the other party goes on-hook, and the hook switch 3 opens, the footer switch controller 1
5 closes the hook switch 3, and the dialer circuit 23 outputs the dial pulse and DTMF signal of the transfer destination under the control of the transfer control unit 21. Then, when the transfer destination goes off-hook, the polarity reversal detection circuit 9 operates, and the polarity reversal detection section 17 detects the off-hook of the transfer destination. The recording/reproducing mechanism 24 is controlled and the magnetic tape is rewound by the amount of previously recorded data.

When the transfer destination enters a password after going off-hook, this password is sent as a DTMF signal from the telephone line NIA+ to the DTMF receiver circuit 13 via the communication circuit 4.

The DTMF receiver circuit 13 analyzes the input DTMF signal and inputs the analyzed password data to the microcomputer 14. In the microcomputer 14, this password is checked, and when a match is detected, the recording/reproducing mechanism 24 starts playing the magnetic tape under the control of the mechanical control section 22, and the recording/reproducing mechanism 24 starts playing back the magnetic tape under the control of the message recording/reproducing control section 20. The voice signal of the message reproduced from the message recording and reproducing circuit 5 is outputted to the telephone line 1 via the telephone communication circuit 4.

<Effects of the Invention> As explained above, in the present invention, rewinding of the magnetic tape is immediately started when the transfer destination goes off-hook, and the message is played back in response to input of a password from the transfer destination. Therefore, at the transfer destination, there is no need to wait while the tape is rewound as in the conventional case, and the trouble of inputting playback commands is also saved, which improves usability.
