Abstract:
1. A communication device, comprising: a facsimile receiving portion that detects a facsimile activation signal that is transmitted from a remote device via an external communication line while a telephone conversation is being executed with the remote device, and that switches from telephone function into facsimile function to execute facsimile receiving operation; and an error preventing portion that prevents the facsimile receiving portion from erroneously executing the facsimile receiving operation based on noise; wherein the facsimile receiving portion includes: a facsimile activation signal detecting portion that detects the facsimile activation signal; a communicating portion that communicates with the remote device; and a receipt-controlling portion that enables the communicating portion into a state, in which the communicating portion is capable of receiving facsimile when the facsimile activation signal detecting portion detects the facsimile activation signal, and wherein the error preventing portion includes: an instruction input portion that receives a near end user's instruction, while telephone communication is being executed with the remote device, the near end user's instruction being for bringing the facsimile activation signal detecting portion into a state, in which the facsimile activation signal detecting portion is capable of detecting the facsimile activation signal without being influenced by noise while telephone communication is being executed with the remote device; and a noise-input preventing portion that prevents the near end user's voice from being inputted in response to input of the near end user's instruction, thereby enabling the facsimile activation signal detection portion to detect the facsimile activation signal without being influenced by the near end user's voice while telephone communication is being executed with the remote device.
