Abstract: An object of the present invention is to provide an image communication apparatus capable of preventing the useless use of not-cheaped BJ ink owing to the innocent behavior of an infant or the like, and capable of preventing the disturbance of the rhythm of a home life by a cat or the like. An image communication apparatus includes operation instructing means for instructing reading operation, image processing operation, image recording operation, calling operation and communication operation; and operation instruction disabling means for disabling an instruction of each operation by the operation instructing means.

Abstract: A communication apparatus receives the identification information of a partner station, and performs a communication operation in accordance with the received identification information. A first detecting unit detects a calling signal. An identification information receiving unit detects the identification information of a calling party upon detection of the calling signal, and a second detecting unit detects whether or not the terminal of the calling party is a data communication terminal. A registration unit registers the identification information of the partner station in a memory, so that whether the partner station is a speech or data communication terminal can be discriminated later. A control unit checks if the identification information receiving unit receives the identification information of the calling party.

Abstract: A communication system in which when an incoming call has arrived, a communication line having the capability of a high sampling rate is automatically selected without assistance of an exchange operator by transmitting an ultra high speed modem indication signal indicating the capability of data communication at an ultra high speed modem rate among the capabilities of a called terminal, and receiving an ultra high speed modem capability signal indicating the capability of an ultra high speed modem of a calling terminal.

Abstract: A facsimile communication system and a communication apparatus reduce a loss time due to the synchronization of transmission/reception and shorten a communication time. They also shorten a communication time in a full duplex communication mode and allow proper switching of the full duplex communication at the transmission/reception replacement. DIS-CFR signals, EOP-DCN signals, NSS-TSI signals and TSI-DCS signals of a facsimile communication protocol are connected by synchronization signals so that the synchronization signals are sent even after the sending of the protocol signal. Thus, the sending of the synchronization signal for one second when the next protocol signal is sent is not necessary and a time required for the protocol signal is shortened.

Abstract: In a data communication apparatus, the baud rate and the bit rate of a modem thereof are set independently of each other according to the condition of data communication. Thus, optimum data communication suited to the line condition can be performed.

Abstract: A data communication apparatus comprises an input unit to input transmission data; a memory to store additional information to be transmitted together with the transmission data by which was input from the input unit; a prohibiting unit to prohibit the transmission of the transmission data in accordance with whether the additional information including the ID information to identify the transmission person or the like has already been stored in the memory or not; notifying units to notify that the transmission of the transmission data was prohibited by the prohibiting unit; a register to register the additional information into the memory; and a requiring unit to require to input the additional information when the transmission of the transmission data is prohibited by the prohibiting unit.
