    • A communication device provided between a data terminal equipment and a telephone line converts an analog signal which is transmitted from a communicating terminal via a telephone line into a digital signal to enable the data terminal equipment to receive A/D converted data in accordance with a command signal from the data terminal equipment. The communication device has a line connector for connecting the phone line with the data terminal equipment upon receiving a ring back signal from the communicating terminal, a judgement unit for judging whether the communicating terminal is a facsimile machine based on a certain signal transmitted from the communicating terminal via the phone line immediately after the line connection, and a signal transmitter for transmitting the data terminal equipment a certain arrival signal representative of arrival of data from the communicating terminal when the judgement unit judges that the communicating terminal is the facsimile machine. The communication device transmits the arrival signal to the data terminal equipment exclusively when it is judged that the communicating terminal is the facsimile machine, thereby facilitating data reception from the facsimile machine and improving a data reception efficiency.
    • 在数据终端设备和电话线之间提供的通信设备将通过电话线从通信终端发送的模拟信号转换为数字信号,以使数据终端设备能够根据命令接收A / D转换的数据 来自数据终端设备的信号。 通信设备具有线路连接器,用于在接收到来自通信终端的回铃信号时将电话线与数据终端设备连接;判断单元,用于基于从通信发送的特定信号判断通信终端是否是传真机 以及信号发送器,用于当判断单元判断出通信终端是传真机时,向数据终端设备发送表示来自通信终端的数据到达的特定到达信号。 通信设备在判断通信终端是传真机时专门将到达信号发送到数据终端设备,由此便于来自传真机的数据接收并提高数据接收效率。

    • An object of the present invention is to provide a facsimile machine having a telephone conversation function, which can securely shift the facsimile communication mode to the telephone conversation mode after facsimile communication even if an error occurs during facsimile communication, without using a telephone conversation reservation function. After facsimile communication is started, when facsimile communication is stopped through the transmission of predetermined signals between the calling party side facsimile machine and the receiving party side facsimile machine in case image data to be transmitted is completely transmitted or when a communication error occurs because of paper jamming, the main controller (12) keeps occupying the communication line (1) occupied by the line controller (2), and the signal sound on the occupied communication line (1) is externally emitted by the speaker (11). When the calling party recognizes that the receiving party requests a call depending on the signal sound transmitted from the communication line (1) and externally emitted by the speaker (11) and lifts the handset (3), the lifting of the handset (3) is detected by the hook switch (4). The main controller (12) then controls the line controller (2) to enable conversation with the receiving party side facsimile machine via the handset (3).
