Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a communication device such as a facsimile communication device, and more particularly to a communication device having a function of storing image data to be transmitted in advance and transmitting the image data at a predetermined timing.

[0002]

2. Description of the Related Art As a communication device, for example, a facsimile communication device used by connecting to a telephone line can be mentioned. Some facsimile communication apparatuses have a so-called reserved transmission function of storing read image data in a memory once and transmitting it at a predetermined timing, in addition to a normal transmission function of immediately transmitting the read image data. is there.

Further, the main terminal unit inquires of a plurality of sub-terminal units sequentially as to whether or not there is a transmission request, and if there is a transmission request, the sub-terminal unit is instructed to start data transmission, and the transmission is started. There is a communication device having a so-called polling function that makes an inquiry to the next sub-terminal device when there is no request. The sub-terminal device is designated by the address signal included in the signal for inquiry, and the sub-terminal device side transmits data when there is a transmission request, and transmits the EOT signal (transmission end signal) when there is no transmission request. .

[0004]

In the facsimile communication apparatus as described above, when executing the reservation transmission function,
Destination information is stored in advance together with the image data. For example, when the image data is being transmitted to a certain destination terminal device and the destination of the other image data stored in advance is the same as the destination of the image data being transmitted, the other image data is transmitted. Can be subsequently transmitted after the transmission of the image data is completed. That is, it is determined whether or not the transmission destination information stored in advance matches the image data being transmitted, and if they match, the image data is continuously transmitted. Such prior art is disclosed in, for example, Japanese Patent Laid-Open No. 61-224568.

However, in the above prior art, when the image data is received, when the data reception is completed, the line with the partner terminal device is cut off, and communication with the same partner terminal device is performed again. Then, a call operation is performed, and a predetermined facsimile communication control procedure is further performed to transmit the image data. In this way, even though the same device is used for communication, the connection line is cut off, which requires a troublesome operation and time for reconnection. Further, when the other terminal device connects a line with another communication device at the time of reconnection, there arises an inconvenience of having to wait until the line is cut off. Such an inconvenience occurs not only during normal data reception, but also during data reception using the polling function.

An object of the present invention is to receive data when
It is an object of the present invention to provide a communication device capable of continuously transmitting data after the end of data reception without disconnecting the line when the other terminal device in communication has data to be transmitted.
