Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a facsimile machine with the functions of a cordless telephone.

2. Description of the Related Art Currently, facsimile devices that use telephone lines to communicate image information and cordless telephones that combine a base unit connected to a telephone line and a cordless handset are in widespread use. It is conceivable that the device may be used by connecting it to a cordless telephone.

Therefore, a device in such a state will be described as a conventional example with reference to FIG. First of all, here PSTN (Public
ic 5w1tched Te1ephone Net
A cordless telephone 4 is connected via a connector 3 to a facsimile device 2 connected to a telephone line 1 such as a telephone line 1 such as a telephone line 1, such as a telephone line 1, and each cordless telephone 4 has a pair of base units 7 each equipped with a handset 5 and a wireless communication device 6. and the slave device 8.

In such a configuration, by doing as described above, the facsimile device 2 can be used to send and receive image information, and the cordless telephone 4 can be used to make calls by wireless communication.

Incidentally, when the facsimile device 2 and the cordless telephone 4 are combined as described above, commercially available products that are not related to each other can also be used.

Problems to be Solved by the Invention As mentioned above, the facsimile machine 2 and the cordless telephone 4
By combining these, it is possible to send and receive image information and make wireless calls.

Here, the facsimile device 2 described above is generally configured to be equipped with a handset (not shown) and capable of making calls, and in such a device, the input signal from the telephone line 1 is transmitted to the facsimile device. Many devices are equipped with automatic switching means that selectively connects either the facsimile unit or the handset to the telephone line 1 by identifying whether the facsimile unit is a signal or not.

However, such automatic switching means is undesirable because it takes time to identify the communication destination, which may cause discomfort when the communication destination requests a telephone conversation. Therefore, if the facsimile device 2 is used less frequently and the cordless telephone 4 is used more frequently depending on the usage situation, the connection with the telephone line 1 is fixed to the cordless telephone 4 side by, for example, turning off the automatic switching means. However, in this case, in order to use the facsimile machine 2, the user would have to move from the position of the handset 8 to the position of the facsimile machine 2 and operate the equipment, making the work complicated.

Means for Solving the Problem The base unit has a built-in facsimile unit and a wireless communication device, and the slave unit is equipped with a cordless handset that wirelessly communicates with the wireless communication device of the base unit, so that the input signal from the telephone line is transmitted to the facsimile unit. An automatic switching means is provided for selectively connecting one of the facsimile section of the base unit and the wireless communication device to the telephone line by identifying whether the signal is a signal, and the operation of the automatic switching means is controlled according to the operation of the handset of the slave unit. A switching control means is provided.

The automatic switching means identifies whether the input signal from the telephone line is a facsimile signal and selectively connects one of the facsimile section of the base unit and the wireless communication device to the telephone line, and the switching control means determines whether the input signal from the telephone line is a facsimile signal or not. By controlling the operation according to the operation of the handset of the handset, the cordless structure allows you to set the standby mode such as switching and fixing the connection to the telephone line to either the wireless communication device or the facsimile unit or activating the automatic switching means. This can be done with the handset of the handset, and while the automatic switching means is in operation, the wireless communication device of the base unit is activated only after the automatic switching means identifies that the input signal from the telephone line is a voice signal. This prevents the transmission of unnecessary radio waves.

Embodiment An embodiment of the present invention will be explained based on FIGS. 1 and 2. First, the facsimile 9 with a cordless telephone according to this embodiment is formed of a base unit 10 connected to a telephone line 1 and a cordless handset 11. First, the base unit 10
In this structure, a telephone line 1 is connected to a voice synthesis circuit 14, a modem 15, a handset 16, an I10 boat 17, etc. via an incoming call detection circuit 12, various relays 13, etc., and this I10 port 17 is connected to an automatic switching means. It is connected to the bus 19 of the CPU 18 which is also a switching control means. Here, this bus 19 includes various types of memory 2.
A facsimile unit 25 consisting of a keyboard 22, a printer unit 23, a scanner 24, etc. is connected together with the 0.21, and a wireless communication device 27 is further connected via a serial I10 port 26.

Further, the handset 11 is formed as a handset, and includes a CPU, a memory 28, 29, a keyboard 30, etc.
A speaker 35 and a microphone 36 for telephone calls are connected to a wireless communication device 34 that is connected to a bus 32 of 31 via a serial I10 port 33 or the like.

With such a configuration, the cordless telephone facsimile 9 can wirelessly control various operations of the base unit 10 by operating the keyboard 30 of the slave unit 11. For example, when changing the standby mode of the main unit 10 to the automatic switching mode, the CP
A signal is transmitted from U31 to the wireless communication device 34 via the serial I10 port 33, and the signal is wirelessly transmitted from the wireless communication device 34 of the child device 11 to the wireless communication device 27 of the base device 10. Therefore, the wireless communication device 27 of this base unit 10
The signal received by the CPU 18 is transmitted to the CPU 18.
Under the control of U18, the standby mode of the device becomes an automatic switching mode.

Therefore, the operation of the cordless telephone facsimile 9 in the automatic switching mode will be explained based on the flowchart shown in FIG. First, when a signal input from the telephone line 1 is detected, the speech synthesis circuit 14 is activated and, for example, ``This telephone is a facsimile.'' If you wish to send a facsimile, please press the start button. If you are making a call, please wait for a while. ” is output to telephone line l. At this time, at the same time as this voice guidance is output, the modem 15 detects whether or not a facsimile signal such as CNG is input. If this signal is detected, the telephone line 1 is connected to the facsimile section 25. . If a facsimile signal is not detected from the telephone line l, a response signal such as NSF is output to reconfirm whether the communication destination is a facsimile device, and when this operation reaches a predetermined number of times, the communication destination requests a call. It is determined that the telephone line 1 is connected to the wireless communication device 27. Then, a calling signal is transmitted from the wireless communication device 27 of the base device 10 to the wireless communication device 34 of the handset 11, a ringing sound is output, and the user makes a call using the handset 11.

In other words, in this facsimile 9 with a cordless telephone, during the automatic switching mode, the wireless communication device 27 of the base unit 10 is activated after identifying that the input signal from the telephone line 1 is a voice signal, thereby eliminating unnecessary radio waves. Since transmission is prevented, the power consumption of the device is reduced.

Here, since automatic switching of the telephone line l as described above takes time to operate, it is not preferable when the other party requests a telephone conversation as described above. Therefore, if the cordless telephone facsimile 9 is used less frequently as a facsimile device and more often as a telephone depending on the usage situation, the wireless communication device 27 can connect to the telephone line 1 by operating the keyboard 30 of the handset 11. It can be fixed by switching to In this case, since this operation can be performed using the cordless handset 11, the user does not need to move to the base unit 10 to operate the device, and similarly, the user can cancel the above-mentioned connection state and switch automatically. When setting the mode, the handset 11
There is no need for the user to move to the location of the base unit 10 just by operating the .

In this embodiment, the facsimile 9 with a cordless telephone is illustrated in which the facsimile section 25 is built into the base unit 1o, but the present invention is not limited to the above embodiment. For example, the facsimile section and the cordless telephone are separate. A system configured as a body (not shown) or the like may also be implemented. In this case, for example, the device can be manufactured as a cordless telephone, and a base unit can be inserted between a commercially available facsimile machine and a telephone line, and the connection to the telephone line can be controlled by the slave unit. Become.

Effects of the Invention As described above, the present invention has a base unit with a built-in facsimile unit and a wireless communication device, and a handset with a cordless structure that wirelessly communicates with the wireless communication device of the base unit. An automatic switching means is provided to identify whether an input signal is a facsimile signal and selectively connect one of the facsimile section of the base unit and the wireless communication device to the telephone line, and the operation of this automatic switching means is controlled by the handset of the slave unit. By providing a switching control means that controls according to the operation, the cordless structure can switch and fix the connection with the telephone line to either the wireless communication device or the facsimile unit, or set the standby mode to activate the automatic switching means. The work is easy as it can be done using the handset of the handset and the user does not have to move to the base unit to operate the equipment.Also, while the automatic switching means is operating, the input signal from the telephone line is converted into an audio signal. By activating the base unit's wireless communication device after the automatic switching means identifies that the device is the one that It is something.
