  However, the above-described conventional call recording adapter device (FIG. 3) receives transmission / reception voices as analog data from a button telephone connected thereto, and only digital data of the PCM interface from a telephone that digitally outputs call voice. Since transmission / reception voices are output, recording is impossible when connected to a telephone that digitally outputs call voice, and it is possible to meet the demand for recording call voices on digital lines such as ISDN lines that have become widespread in recent years. There is a problem that it is not possible.

  Further, the digital open voice device described in Patent Document 1 can record digital voice data on a digital line, but has a problem that it cannot be applied to an existing analog voice output telephone.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a call recording adapter device that enables call recording by connecting a cassette coder to telephones of both analog and digital types.

  The adapter for call recording according to the present invention transmits / receives speech by control data from a CODEC (7 in FIG. 1) for converting between analog voice data and digital voice data and a digital voice output telephone (11 in FIG. 1). A digital I / F unit (6 in FIGS. 1 and 2) that sets the input / output timing of digital audio data to CODEC, and a first switch that sets the type of telephone to which the call recording adapter device is connected to the CPU (9 in FIGS. 1 and 2) and when the call recording adapter device is connected to the digital voice output telephone under the control of the CPU, the analog voice data is inputted via the CODEC, while the analog voice output telephone is used. When connected to (21 in FIG. 2), a second switch (8a in FIGS. 1 and 2) for switching to directly input analog audio data and a CPU And a third switch (FIGS. 1 and 2) for outputting analog voice data from the recording medium (10 in FIGS. 1 and 2) to the digital voice output telephone or directly to the analog voice output telephone via the CODEC. 8b), and the CPU switches the second switch and the third switch to the CODEC side according to the control data from the telephone connected to the call recording adapter device and the setting of the first switch. And

  As described above, according to the present invention, when a digital audio output telephone is connected, the CODEC and the digital I / F unit function to convert the digital audio data into analog audio data and record it on the recording medium. When the analog audio output telephone is connected, recording to the recording medium and reproduction from the recording medium are performed without using the CODEC and the digital I / F unit. Since the voice data path is switched, it is possible to record a call regardless of whether a digital voice output telephone or an analog voice output telephone is connected.

On the other hand, the analog voice data from the recording medium is controlled under the control of the second switch for switching to input the analog voice data directly when it is connected to the key telephone. A third switch that outputs to a digital voice output telephone or an analog voice output telephone directly through CODEC is provided.

The CPU switches the second switch and the third switch to the CODEC side according to the setting of the first switch. The call recording adapter device of the present invention includes fourth, fifth and sixth switches. The fourth switch performs setting for controlling the sixth switch to the CPU. The fifth switch is ON / OFF for outputting analog voice data from the digital telephone set via the first switch or the direct key telephone set to the cassette coder via the two-wire four-wire converter under the control of the CPU. Turn off.

  The sixth switch functions when there is a setting by the fourth switch, and outputs the analog audio data from the two-wire / four-wire converter to the third switch. The third switch outputs the analog voice data from the sixth switch to either the CODEC or the key telephone by the control from the CPU based on the setting by the first switch.

  Next, embodiments of the present invention will be described in detail with reference to the drawings.

Handset 24, headset 25, microphone 26 for collecting sound, and speaker 27 for outputting sound.

  The CPU 2 performs ON / OFF control of the switch 4a on the path for sending the analog voice data of the transmission / reception to the cassette coder 10 based on the control data from the CPU / communication / voice IC 12 of the digital telephone 11 or the CPU 22a. With this setting, ON / OFF control of the switch 4b on the path for sending the reproduced sound from the cassette coder 8 to the other party is performed. Further, the CPU 2 switches the switches 8a and 8b to the CODEC 7 side according to the setting of the switch 9.

  The switch 9 sets the type of telephone (digital telephone 11 or button telephone 21) to which the call recording adapter device 1 is connected in the CPU 2. The switch 5 performs setting for controlling the switch 4b to the CPU 2. The CPU 2 performs predetermined control on the switches 8a, 8b, 4a and 4b based on these settings.

  The switch 8a inputs analog voice data through the CODEC 7 when the call recording adapter device 1 is connected to the digital telephone 11 under the control of the CPU 2 (FIG. 1), while the call recording adapter device 1 is a key telephone. When connected to the terminal 21 (FIG. 2), switching is performed so that analog voice data is input directly from the key telephone 21.

  As shown in FIG. 1, when the call recording adapter device 1 is connected to a digital telephone 11 and makes a call through the handset 13, the digital audio data of the transmission / reception is sent from the CPU / communication / voice IC 12 for call recording. The data is sent to the adapter device 1 and received at the timing generated by the digital I / F unit 6 by the CODEC 7 in the call recording adapter device 1. The digital audio data of the transmission / reception received by the CODEC 7 is converted into analog audio data, and is sent to the cassette coder 10 via the switch 8a, the switch 4a and the 2-wire 4-wire conversion unit 3. The cassette coder 10 records the analog voice data of the received transmission / reception. Similarly, when a call is made using the headset 14 or the microphone 15 and the speaker 16, the sound is recorded in the cassette coder 10.

  Analog audio data of the reproduced sound from the cassette coder 10 is input to the CODEC 7 via the two-wire / four-wire converter 3, the switch 4b and the switch 8b. The input analog audio data is converted into digital audio data by the CODEC 7 and sent to the CPU / communication / audio IC 10 with the timing generated by the digital I / F unit 6. The CPU / communication / voice IC 12 sends analog voice data to the handset 13, the headset 14, the speaker 16, or the other party of the digital telephone 11.

  On the other hand, as shown in FIG. 2, when the call recording adapter device 1 is connected to the digital telephone 11 and makes a call through the handset 23, the analog voice data of the transmission / reception is sent from the communication / voice IC 22b for call recording. The data is sent to the adapter device 1 and directly received by the switch 8a in the call recording adapter device 1.

  The received analog audio data of the transmission / reception is sent to the cassette coder 10 via the switch 4a and the 2-wire 4-wire conversion unit 3. The cassette coder 10 records the analog voice data of the received transmission / reception. Similarly, when a call is made using the headset 24 or the microphone 25 and the speaker 26, recording is performed in the cassette coder 10.

  Analog audio data of the reproduced sound from the cassette coder 10 is directly sent to the communication / audio IC 22b via the 2-wire 4-wire converter 3, the switch 4b, and the switch 8b. The communication / voice IC 22 b sends analog voice data to the call partner of the handset 23, headset 24, speaker 26, or key telephone 21.
