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.

Image communication apparatus

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. When the identification information of the calling party is received, the control unit checks if the-received identification information is registered in the memory, and selectively executes a speech communication process and a data communication process in accordance with the checking result and the detection result of the second detecting unit.

Communication apparatus for receiving identification information of partner station, and executing communication operation in accordance with received identification information

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.

Communication system having the capability of selecting an optimum communication mode from a plurality of modes, depending on the type of equipment at a party to be communicated with

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. An ANSam signal to disable a function of an echo suppressor is sent when a call is detected and a calling station thereafter sends a protocol signal and an image signal in a manner not to cause signal interruption of 50 ms or longer, and at transmission/reception replacement at the end of the image signal from the calling station, a called station sends an ANSam signal and sends a protocol signal.

Data communication apparatus and facsimile apparatus

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.

Data communication apparatus for setting the baud rate and bit rate of a

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.
