TW239246B - Faxing machine - Google Patents

Abstract

A receiving device of faxing machine includes: 1. one control circuit connected electrically to the voice synthesizer, voice frequency detecting circuit, voice detecting circuit, and sending out properly responding signal; 2. one microprocessor connected electrically to each components in the faxing machine to control the function and operation of each component; 3. one coupler connected electrically to the telephone line and the blower, which can do auto-switch and is connected with microprocessor, modem, voice synthesizer, voice frequency detecting circuit and voice detecting circuit; 4. one faxing modem connected electrically to the coupler and microprocessor to modulate or demodulate the signal of faxing information, and sending out ringing signal to the blower; 5. the first time storage connected electrically to the microprocessor to set the cycle time of signal detection; 6. the second, third, and fourth time storage connected electrically to the microprocessor to set the stop length between the ringing tone, the length of each ringing and the total time of ringing; It features that the voice synthesizer connected electrically to the coupler to send out preset at least one voice signal to the calling side, the coupler can poll many types of signal and control to the correct component or calling side, and the control circuit can detect not only fax calling tone but also faxing protocol signal to operate polling fax sequentially, and by the voice frequency detecting circuit and voice detecting circuit to detect the human voice on the calling side and the signal of hang-off communication, then switching into the telephone mode and cut-off mode without entering the faxing mode with at least 35 seconds of standard processing time.
