話機の着信検出装置。[Claims for Utility Model Registration] An incoming call detection circuit consisting of a light emitting part and a light receiving part is connected to a telephone line via a ringing sound generating circuit which receives a ringing signal and outputs a ringing sound signal, The output is given to a line capturing means for capturing a telephone line, while the output of the light emitting section is guided to a transformer-coupled speaker, and the speaker receives a reproduced sound signal from a recording medium or a synthesized sound signal from a speech analysis and synthesis circuit. The telephone is configured to provide a telephone with an incoming call malfunction prevention circuit that receives the calling signal and electrically connects the output side of the light emitting part and the input side of the transformer. Telephone incoming call detection device.
