It is an object of the present invention to provide a communication terminal capable of preventing the circuit to be released when a hook key is operated in the case the circuit is being closed forcibly. It is further object of the present invention to provide a communication terminal capable of informing the functions capable of being used in the case the circuit is being closed due to the malfunction of the recording unit. In the case the recording unit 50 fails to operate and the image memory 80 is exhausted, and when it is set to close the telephone line L based on the operation of the circuit closing key 69, the facsimile receiving is prevented from being carried out by closing the telephone line L. Then, the operation of the hook key 66 is invalidated under this condition. Therefore, the telephone line L is not released even if the hook key 66 is operated. Thus, when the telephone line L is being closed forcibly, it can be prevented from the telephone line L being released even if the hook key 66 is operated. In the case the recording unit 50 fails to operate and the image memory 80 is exhausted, and when it is set to close the telephone line L based on the operation of the circuit closing key 69, the facsimile receiving is prevented from being carried out by maintaining the state of closing the telephone line L. Therefore, even in the case the recording unit 50 fails to operate and the image memory 80 is exhausted, and the telephone line L is being closed since it is set to have the telephone line L closed based on the operation of the circuit closing key 69, the functions capable of being used can be informed.
