Abstract
Abstract A facsimile apparatus incorporating a cordless telephone set includes a base unit transmitting and receiving a signal to and from a remote unit with a radio signal, and a facsimile communication device. During voice communication with the remote unit via a telephone line, an alarm is issued to the user when the voice communication continues for more than a predetermined time period. An alarm is also given to the user of internal line voice communication when there is a telephone call from an external line during voice communication between the base unit and the remote unit. Therefore, the reception of a reception signal to the facsimile apparatus is not inhibited because an alarm is issued when voice communication continues for more than a predetermined time period and when there is a telephone call from an external line during internal line voice communication.

Dependent Claim
187 words
A facsimile apparatus comprising: first communication means for transmitting and receiving an aural signal via telephone line, said first communication means further including an internal line voice communication device for voice communication via electromagnetic, the internal line voice communication device being selectively connectable to the telephone line yet operable without being connected to said telephone line; second communication means for transmitting and receiving an image signal via said telephone line; calling signal detecting means for detecting a calling signal to at least one of said first and second communication means from said telephone line; determining means for determining whether or not said internal line voice communication device is being used by a user when said calling signal detecting means detects said calling signal; alarm means for generating an alarm at the internal line voice communication device, when said determining means determines that said internal line voice communication device is being used by the user; and connecting means for automatically connecting said telephone line to said second communication means when said determining means determines that said internal line voice communication device is not being used by the user.
Claim 4
Dependent Claim
187 words
A facsimile apparatus comprising: first communication means for transmitting and receiving an aural signal via telephone line, said first communication means further including an internal line voice communication device for voice communication via electromagnetic, the internal line voice communication device being selectively connectable to the telephone line yet operable without being connected to said telephone line; second communication means for transmitting and receiving an image signal via said telephone line; calling signal detecting means for detecting a calling signal to at least one of said first and second communication means from said telephone line; determining means for determining whether or not said internal line voice communication device is being used by a user when said calling signal detecting means detects said calling signal; alarm means for generating an alarm at the internal line voice communication device, when said determining means determines that said internal line voice communication device is being used by the user; and connecting means for automatically connecting said telephone line to said second communication means when said determining means determines that said internal line voice communication device is not being used by the user.
Claim 5
Dependent Claim
186 words
A facsimile apparatus comprising: first communication means for transmitting and receiving an aural signal via telephone line, said first communication means further including an internal line voice communication device for voice communication via electromagnetic waves, the internal voice communication being selectively connectable to the telephone line yet operable without being connected to said telephone line; second communication means for transmitting and receiving an image signal via said telephone line; calling signal detecting means for detecting a calling signal to at least one of said first and second communication means from said telephone line; determining means for determining whether or not said internal line voice communication device is being used by a user when said calling signal detecting means detects said calling signal; alarm means for generating an alarm at the internal line voice communication device, when said determining means determines that said internal line voice communication device is being used by the user; and connecting means for automatically connecting said telephone line to said first communication means when said determining means determines that said internal line voice communication device is not being used by the user.
