These terminals are provided as terminals for connecting a telephone line and a telephone line. Ordinary facsimile device 201
Then, the signal is transmitted and received via the line terminal. In order to start transmission / reception, since the start key (the key for starting the communication) becomes effective while the telephone connected to the TEL terminal is in the off-hook state, the pseudo off-hook device 45 is used to pseudo off-hook. Create and input a signal. This embodiment is almost the same as the wireless interface 103 on the mobile phone side shown in FIG. 2, but since the facsimile apparatus 201 performs 2-wire 4-wire conversion by the internal NCU, it has a 2-wire line terminal. Sending and receiving is possible just by connecting. This is because it connects directly to the telephone line. Therefore, the 2-wire to 4-wire converter 31 is provided between the impedance matching device 32 and the facsimile device 201.
