3, the connector 14, and magnets 20d on both sides,
20c. The fixed housing 120 includes a microphone 122, a dial switch 121, a display (LCD) 111, and magnets 20a and 20b, a connector 14, and a secondary battery (not shown) on both sides.

The magnet 20d corresponds to the magnet 20a, and the magnet 20c corresponds to the magnet 20b. In such a configuration, when performing wireless data communication, wireless data communication can be started by inserting only the first housing 12b into the card slot of the personal computer.

When the portable telephone is housed, the magnet 20d is attached to the magnet 20a, and the magnet 20c is attached to the magnet 20b. That is,
The first housing 12b is placed on the second housing 11b.

[0088]

According to the present invention, there is provided a housing having an interface part conforming to a predetermined standard, having a physical shape conforming to the standard, and capable of being inserted into an insertion port provided in an external terminal device. With the provision, the interface unit can be easily connected to the terminal device by inserting the housing into the insertion port of the terminal device without using accessories such as a cable. In addition, since one device has a wireless data function by a storage unit and a modem unit and a wireless communication function by a voice input unit and a voice output unit and a modem unit, accessories such as a cable to a microphone and a speaker are provided. And the portability can be improved without using any of them. If the standard is the Japan Electronic Industry Development Association (JEIDA) or the Personal Computer Memory Card International Association (PCMCIA) standard, compatibility with the conventional data communication interface can be maintained.

Further, in a state where the joint housing is opened at a predetermined angle with respect to the housing, a call can be made using a voice input unit and a voice output unit, and the housing is inserted into an insertion port provided in a terminal device. Can perform data communication by the terminal device. Since the joining housing having a substantially same plane as the casing and having an arbitrary thickness is provided and the joining casing is electrically separated from the casing, portability can be improved. Since the groove provided in one of the joining housings and the housing is slid by the other housing and locked at a predetermined position, the joining housing and the housing can be integrated.

The joining housing and the housing can be integrated by mutual attraction between the magnet on the surface of the joining housing and the magnet on the surface of the housing. Since the invalidation circuit invalidates the dial information sent when the sheet switch is pressed by mistake when the sheet switch is inserted into the insertion slot of the terminal device, erroneous operation can be prevented.

Since the secondary battery is charged by the power from the power supply provided in the terminal device when the interface unit is inserted into the connector provided in the terminal device, the consumption of the secondary battery can be suppressed. Since the state of charge of the secondary battery unit is displayed on the display, the usage amount of the secondary battery can be grasped.

When making a call, another secondary battery unit is connected to the housing via the interface unit to receive power supply from another secondary battery unit. When performing data communication, another secondary battery unit is detached from the housing, and the housing is connected to the insertion port provided in the terminal device to charge the secondary battery unit, so that consumption of the secondary battery unit can be reduced. .

When the housing is inserted into the insertion slot provided in the terminal device, the control unit exchanges information stored in the memory between the memory and the terminal device, thereby increasing the utility value of the present device. Since the control unit writes the personal identification password from the switch to the memory and checks the password between the memory and the terminal device, it is possible to limit the exchange of personal information with the terminal device.
