A cordless telephone 4 is connected to a facsimile apparatus 2 connected to a telephone line 1 such as a telephone network 1 by a connector 3 or the like. The cordless telephone 4 has a pair of parents each having a handset 5 and a wireless communication device 6. It is formed by the machine 7 and the slave 8.

In such a configuration, the image information can be transmitted and received using the facsimile apparatus 2 as described above, and the cordless telephone 4 can make a wireless communication. When the facsimile apparatus 2 and the cordless telephone 4 are combined as described above, commercially available products that are not related to each other can be used.

Problems to be Solved by the Invention By combining the facsimile apparatus 2 and the cordless telephone 4 as described above, transmission and reception of image information and wireless communication can be performed.

Here, when the transmission of the image information to the facsimile apparatus 2 is started, the telephone line 1 may be disconnected because the destination facsimile apparatus is in operation. In such a case, for example, the dialing to the transmission destination is repeated by the slave unit 8 of the cordless telephone 4 in a state where the original is set in the facsimile apparatus 2, so that the worker can be away from the facsimile apparatus 2. It is possible to open the telephone line 1 while performing other operations.

However, even if the telephone line 1 is opened to the transmission destination in this way, the operator needs to return to the position of the facsimile machine 2 and perform the transmission operation again to start transmitting the image information. It is complicated and not preferable.

Means for Solving the Problems A facsimile unit and a wireless communication device are provided in a base unit, and a cordless handset for performing wireless communication with the wireless communication device is provided in a slave unit. One of the facsimile unit of the base unit and one of the wireless communication device is provided. A switching means for connecting the telephone line to the telephone line, and a signal detection means for detecting a response signal of a destination facsimile apparatus for controlling the start of transmission of image information of the facsimile section, connected between the switching means and the wireless communication apparatus, Switching control means is provided for switching the connection of the telephone line by the switching means from the wireless communication device to the facsimile unit in accordance with the detection of the response signal by the detection means.

Operation When the connection between the telephone line and the facsimile unit of the master unit to which the image information transmission work is set is interrupted and the connection to the telephone line is switched to the wireless communication device by the switching unit, the operation of the slave unit When the telephone line with the destination is opened and the signal detection means detects the response signal of the destination facsimile apparatus, the connection with the telephone line is disconnected from the wireless communication apparatus to the facsimile part by the switching means operated by the switching control means. Instead, the transmission of the image information is started so that the cordless structure of the handset can be used for dialing on the disconnected telephone line, so the user waits for the transmission of the image information. You can move from the location of the master unit to another location while you are in the office, and when the telephone line is opened to the destination, the telephone line is automatically connected to the facsimile unit and the transmission of image information starts. Therefore, it is not necessary for the user to return to the position of the parent device and repeat the transmission operation.

Note that the same parts as those in the above-described conventional example are denoted by the same names and reference numerals, and description thereof is omitted. First, a facsimile 9 with a cordless telephone according to the present embodiment has a structure in which a base unit 10 connects a radio communication device 6 and a facsimile unit 12 to a control circuit 11 connected to the telephone line 1 as illustrated in FIG. The handset 13 has the same structure as the handset 8 of the cordless telephone described above.

The structure of the master unit 10 will be described below in detail with reference to FIG. First, the control circuit 11 is a switching means connected to the telephone line 1 and is a CML (Current Mode Logic).
A mixer 15 is inserted into one of the parallel wires between the relay 14 and the facsimile unit 12, and a part of signal detection means is provided between the mixer 15 and the wire from the CML relay 14 to the wireless communication device 6. The detection transformer 16 for the CED signal (called station identification signal) is continued. In the facsimile unit 12, a facsimile processing circuit 17 is directly connected to the CML relay 14, and the mixer 15 is a signal detection unit.
A facsimile control circuit 19, which is a switching control means connected via a CED signal detection circuit 18, is connected to the facsimile processing circuit 17 and the CML relay 14.

In such a configuration, the facsimile 9 with a cordless telephone normally connects one of the facsimile unit 12 and the radio communication device 6 to the telephone line 1 by a CML relay 14,
It selectively performs image information communication work and cordless telephone calls.

Here, when image information is transmitted by the facsimile 9 with a cordless telephone, the facsimile unit 12 is connected to the telephone line 1 by the CML relay 14 and dialing is performed. At this time, for example, a destination facsimile machine (not shown)
If the telephone line 1 is interrupted because the telephone is working, the facsimile 9 with a cordless telephone will
By operating the device 4, the connection with the telephone line 1 is switched to the wireless communication device 6, and the dialing can be repeated by operating the slave device 13. At this time, since the child device 13 has a cordless structure and wirelessly communicates with the parent device 10, the user can freely move from the position of the parent device 10. When a CED signal, which is a response signal output by the destination facsimile apparatus, is input through the dialing performed by the slave unit 13 and the telephone line 1 is opened to the transmission destination, the CED signal is transmitted to the CED signal detection transformer 16. Mixer 15
The connection of the CML relay 14 to the telephone line 1 is transmitted from the radio communication device 6 to the facsimile unit 12 by the facsimile control circuit 19 which operates according to the detection result of the CED signal detection circuit 18. Side and the facsimile processing circuit 17 starts transmission of image information.

As described above, the facsimile 9 with a cordless telephone can perform dialing with the cordless handset 13 even when the telephone line 1 is disconnected when transmitting image information. When the telephone line 1 is opened at the transmission destination, the connection to the telephone line 1 is automatically switched from the wireless communication device 6 to the facsimile unit 12 while the image is being transmitted. Since the information transmission operation is started, the user does not need to return to the position of the base unit 10 or repeat the transmission operation, and can confirm the start of the transmission operation while performing the operation in another place.
