In this case, it is possible to implement a multi-functional part of a recent fixed telephone.

  According to the present invention, a mobile phone can be used indoors in the same manner as a fixed telephone, and does not use a fixed telephone line or a fixed Internet line.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIGS. 1 and 2 are a schematic diagram and a block schematic diagram showing an embodiment of the present invention. A mobile phone 1 to be used is connected to an external communication network, which is a conventionally known function, and is used for calls, the Internet, mails, etc. A transmission / reception communication device 101 capable of various communication, a CPU 102 for controlling various devices and devices, a memory 103, a storage device 104 for storing various software and data, and key buttons and voice input devices (not shown). Etc.), an external input interface 106, an internal output device 107 such as a display screen or a speaker, and an external output interface 108, and use a telephone call, mail, the Internet, etc. like a normal mobile phone. can do.

  On the other hand, the terminal 2 arranged indoors is exposed to the base end which is the insertion part of the mobile phone 1, for example, in the insertion groove 22 of the mobile phone formed in the box-shaped terminal body 21. A terminal input interface 23 and a terminal output interface 24 are connected to the external input interface 106 and the external output interface 108, respectively. For example, the mobile phone 1 is inserted into the terminal 2 like a known charging device. The external input interface 106 of the mobile phone 1 and the terminal output interface 24 of the terminal 2 are connected to the external input interface 108 of the mobile phone 1 and the terminal input interface 23 of the terminal 2 only by being inserted into the groove 22. .

  For example, one terminal side transmission / reception device 31 forming a radio wave type transmission / reception device 3 is disposed on the terminal output interface 24 and the terminal input interface 23 of the terminal 2.

  Further, the terminal 2 is provided with a receiver 4 which is conventionally used in a fixed telephone and incorporates another receiver-side transmitter / receiver 32 forming the transmitter / receiver 3.

  This handset 4 has built-in microphones and push buttons which are external input devices 41a and 41b and a speaker which is an external output device 42 in the same manner as the handset used in conventional fixed-type telephones. 41 and an external input incorporated in the receiver 4 in a so-called cordless state by being transmitted and received between the receiver-side transceiver 32 incorporated in the external output device 42 and the terminal-side transceiver 31 incorporated in the terminal body 21. The terminal output interface 24 and the terminal input interface 23 installed in the terminal body 2 are connected to the devices 41a and 41b and the external output device 42a, respectively.

  The terminal main body 21 includes, for example, a power source (battery) 43 that is built in the transmission / reception device 3 or the receiver 4 and drives the external input devices 41a and 41b and the external output device 42a, and a cellular phone 1 that is inserted. A charger / fixed power supply device 6 for charging the battery 5 for the mobile phone 1 incorporated in the mobile phone 1 is disposed.

  Further, the terminal output interface 24 and the terminal input interface 23 of the terminal main body 21 include a printer having a scanner function arranged in parallel with the terminal main body 21 constituting the external output device 41c and the external input device 42b. The input / output interface 43 is connected.

  Furthermore, connected devices such as a television receiver (monitor) 7, a speaker 8, and a personal computer 9 are connected to the input / output interface 43 of the terminal main body 21.

  In the present embodiment, since the terminal output interface or terminal input interface 23 installed in the terminal body 21 is connected to the external output device 41 and the external input device 42 by the transmitting / receiving device 3, the receiver 4 is a so-called cordless type. The terminal output interface or the terminal input interface 23 installed in the terminal body 21 by the direct code without using the transmission / reception device 3 is connected to the external output device 41 and the external input device 42. The terminal output interface 2 and the terminal output interface 24 installed in the mobile phone 1 and the external output interface 108 and the terminal input interface 23 of the mobile phone 1 are set to be wireless, respectively. The terminal input interface 23 may be built in the receiver 4 and directly connected to the mobile phone 1 and the receiver 4 in a wireless manner. In this case, a fixed telephone type without using the terminal body 21 may be used. By operating the receiver 4, communication by the mobile phone 1 can be performed.

  In order to use the terminal 2 of the mobile phone 1 according to the present embodiment, the mobile phone 1 has the same function as that of a normal mobile phone when the user goes out normally. Use it as a mobile phone.

  Of course, when the user is indoors such as at home or at work, it can be used as a mobile phone as it is, but basically the mobile phone 1 is inserted into the insertion groove 22 of the terminal body 21 in the terminal 2. Let's go in. At this time, like the cradle type charger, current is sent from the charging device 6 provided in the terminal body 21 to the battery 5 provided in the mobile phone 1 via a connection terminal (not shown) for charging. A state is formed.

  At the same time, as described above, the external input interface 106 and the external output interface 108 installed in the mobile phone 1 and the terminal input interface 23 and the terminal output interface 24 installed in the terminal 2 are respectively connected.

  Therefore, for example, the CPU 102 converts a signal received by the transmission / reception communication device 101 of the mobile phone 1 into, for example, an audio signal and transmits it to not only the internal output device 107 but also a speaker which is the external output device 42 arranged in the receiver 4. Audio is output.

  Also, input signals from microphones and push buttons, which are external input devices 41 a and 41 b installed in the receiver 4, are sent to the mobile phone 1, processed by the CPU 102, and transmitted by the transmission / reception communication device 101.

  Therefore, by using the function of the mobile phone 1 via the handset of the fixed telephone specification, communication can be performed with the same operation feeling as that of the fixed telephone even if there is no fixed telephone line as in the conventional terminal.

  In the above-described usage method, the case where audio information is mainly transmitted and received has been described. For example, an image signal transmitted to the internal output device from the Internet information obtained in the mobile phone 1 is input / output disposed in the terminal 2. Printed by transmitting to a connected device such as a printer having a scanner function as an external output device 42c connected to the interface 43, a television receiver (monitor) 7, a speaker 8 and a personal computer 9 connected to the input / output interface 43 Can be displayed.

  In addition, input information from a connected device such as a television receiver (monitor) 7, a speaker 8, and a personal computer 9 connected to an external output device 23 such as a printer having the scanner function is input to an external device via the mobile phone 1. It can also be transmitted via a communication network.
