Claims

[Scope of utility model registration request]

A calling signal identifying means comprising a voltage detecting section for detecting the voltage level of the calling signal, a frequency detecting section for detecting the frequency thereof, and a repetition period detecting section for detecting the repetition period thereof; a memory section that stores in advance each data of the voltage level, frequency, and repetition period of a calling signal determined in A facsimile transmitting/receiving device comprising a signal discrimination processing unit that compares each stored data and receives an incoming signal when a match is determined.
